I purchased fgis car from a used car dealership, for over $6,000.00 , which is not a ton of money, but plenty enough to not have instant issues. Since my purchase in june 30, 2026, i have already had all of these issues occur. There is white smoke coming from the left tail pipe, it is sluggish when you push on the gas, there is black soot constantly on my rims that is extreamly hard to remove, the high pressure fuel pump jas failed, I can tell because the oil is higher then it was when o had the oil freshly changed, and it smells of gasoline.inside the oil. The exhaust has stron smell of gasoline. My steering wheel has a loud clinking noise everytime I go over a speed bump on pull into my driveway. Just so many items consistently needing repair or replacement, even though I just had the fuel system cleaned, the oil changed, and filters, and.oil filter too. I checked to see if any of my issues are covered by a recall warranty, because they all are recalled items for my car year, make, and model, but apparently Hyunfai is only covering these dangerous recall items for ul to 10 years. These items shkuld be covered longer, because my carfax states that at least one of these recalled items had already been changed in 2018, and is already broken again!! Hyundai should have covered these extreamly high wear out car parts for a longer period of time, or for the life of the vehicle, if every 5 years your replacing a $1000.00 part, not including labor, like the (HPFP) I was quoted by auto zone for over that price point!! "Ridiculous"! Another item is the air bag cover on the driver side windows area, of the body frame it is loose and keeps un-clipping, i am afraid that it is going to possibly just go off and kill me or something!! Very disappointed right now, that i cannot get any of these recalled items replaced by the manufacturer!!

I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the ABS and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop—despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the ABS and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the ABS module.

Once again I am having to replace a bulb for my vehicle. This will be the second time in 3 months I have had to replace my rear blinker bulb. Not including the 4-5 times per year I have to replace headlight bulbs. This time the wiring has melted and the bulb has nearly melted the lens cover. I only buy the exact OEM recommended bulb every time. Nothing fancy. Just the basic old school bulbs. Every year model around mine has been recalled for this exact issue.

Randomly all controls on my steering wheel (I.e. cruise control, volume for sound, Bluetooth phone controls etc) just stopped working. Now I cannot control the radio, phone or even toggle to see mpg, mileage driven, use cruise control etc. I read there was an extended warranty regarding this issue and my vehicle was or is affected. However it has since expired and upon contacting local dealership they did not even have the parts for that recall.

My 2011 Hyundai Sonata (VIN [XXX] ) was brought to Gateway Hyundai in [XXX] for the mandatory P1326/KSDS engine recall inspection. I had a confirmed appointment on XXX at 7:30 AM. The dealership acknowledged the P1326 code and that the KSDS test was required.Instead of performing the recall, the dealership refused to inspect the vehicle. They contacted a third party who was not in possession of the vehicle and released the vehicle to that person without my authorization. The plates were removed and the vehicle was later sold without my consent. The recall was never performed and the engine defect was never inspected.This is a failure to perform a required safety recall and a violation of chain-of-custody procedures. A vehicle with a known engine failure risk was put back into public circulation without inspection. This creates a safety hazard for the public.I also suffered financial harm including $1,500 in towing, parts, labor, and storage fees. I have a signed tow invoice showing the VIN and the total amount paid.I am requesting that NHTSA investigate Gateway Hyundai’s handling of recall vehicles, review their authorization and release procedures, and take enforcement action if violations are found.

On my 2011 Hyundai Sonata GLS, both rear tail lights have melted to the point that the lightbulbs cannot be extracted and the brake and tail lights no longer work. When I looked into this, I found out this is a common issue on 2011 Hyundai Sonatas. It is almost always caused by excessive heat from the standard incandescent bulbs, which damages the wiring harness and deforms the plastic housing. When I called the closest Hyundai dealer (in Chico, California), they told me the warranty had expired last year and that I should have received a notice about it after I obtained ownership of the car in March 2025 (a little over a year ago). However, I did not receive a notice about this. Since the tail lights do not work properly as a result of this problem, it is a safety issue as it could cause an accident. It should be a recall repair instead of a warranty that expires. My car is still well under the 200,000 mile limit that was set on the extended warranty, but they're refusing to honor that because of the warranty being expired.

The vehicle’s airbag warning light is illuminated. The steering wheel also makes a clicking noise, which appears related to an internal clock spring/coil connector failure. This defect may prevent the driver airbag from deploying properly in a crash, creating a serious safety risk. I contacted O’Brien Hyundai of Normal on 4/23/2026 and was denied repair assistance solely due to vehicle mileage. The vehicle has been well maintained, and this issue involves a critical safety component that should not fail under normal use. I am submitting this complaint due to concerns about airbag system failure and occupant safety.

Your dealership’s own diagnostic report showed no knock sensor code, no engine issues, and no active warning lights. My car was fully drivable when I dropped it off. Within 30 minutes of picking my vehicle up, the check engine light began blinking and the car became completely undrivable. It has not moved since March 20, 2026 at the dealership. The dealership did an additional diagnostic and found a knock sensor that was not there during the first diagnostics and have stated that my engine has too many miles to be covered uder warranty.

The vehicle suddenly stopped and died while driving. The mechanic confirms that the engine is gone, contact Hyundai. Ourisman of Rockville and Hyundai Motor America (HMA) refuses to replace the engine for free. The vehicle has now developed a severe engine knock consistent with the well-documented defect affecting Hyundai’s Theta II engines. Hyundai has publicly acknowledged this issue and issued a major recall covering approximately 470,000 vehicles with the following specifications: • Model Years: 2011–2012 • Engines: 2.0L and 2.4L • Manufacturing Period: December 11, 2009 – April 12, 2012 Hyundai and federal regulators identified the safety concern as manufacturing debris that could restrict oil flow to rod bearings. This defect can lead to engine knocking and eventual engine failure. Critically, Hyundai has acknowledged that engine failure may stall the vehicle while driving, significantly increasing the risk of a crash. Hyundai’s official remedy for this defect required dealerships to: • Inspect engines for bearing noise • Replace the engine if necessary • Honor Hyundai’s extended engine warranty of 10 years / 120,000 miles for affected vehicles. This issue has also been the subject of significant litigation, including the class action lawsuit Case No. [XXX], filed January 23, 2018, against Hyundai Motor America (HMA), Kia Motors America, Inc. (KMA), Hyundai Motor Company (HMC), and Kia Motors Corporation (KMC). Despite these well-known issues, Ourisman of Rockville failed to disclose any of the following when selling my daughter's this vehicle: 1. The widespread engine defects associated with the 2011 Hyundai Sonata. 2. The recall and safety concerns related to debris restricting oil flow to rod bearings. 3. The extended Hyundai engine warranty covering affected vehicles up to 120,000 miles. This omission is particularly concerning because this defect presents a serious safety hazard and a clear and present danger.

While driving at an undisclosed speed, the vehicle lost power, an alarm sounded for the braking system, and the vehicle went into LIMP Mode and the vehicle failed to exceed 15 MPH. After originally paying out-of-pocket for an ABS module at the dealer and was informed that the engine needed to be repaired and the brakes needed to be replaced. The vehicle was towed to the residence where an independent mechanic repaired the vehicle. There was a recall for the ABS module and the contact returned to the dealer, and the dealer confirmed that the independent mechanic had correctly installed the part. The dealer performed the official recall repair and refused to reimburse the contact for the previous expenses. Three months later, the braking system failed again. The contact stated that the vehicle temporarily returned to normal after a restart, but the failure worsened and required a return trip to the dealer for another repair. In January 2026, the failure recurred for a third time with a loud squealing sound. The dealer was not notified of the third failure. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

My 2011 Hyundai Sonata experienced sudden engine failure and the engine is now locked up. The vehicle became inoperable and had to be taken to a Hyundai dealership. The dealership confirmed the engine is locked and not drivable. Hyundai denied the engine replacement claim stating the vehicle has A04/A08 branding indicating the engine originates from a scrapped or rebuilt vehicle. However, Hyundai refused to provide any documentation supporting this claim. They also refused to verify the engine serial number against the VIN to confirm whether the engine is original to the vehicle. A NMVTIS vehicle history report shows the title status as ACTIVE with no salvage, junk, or rebuilt branding. Despite this, Hyundai continues to deny the claim without documentation. This vehicle contains the Hyundai Theta II engine that has been the subject of recalls and settlement actions related to premature engine failure. The failure pattern in this case matches the known defect where engines seize or lock up unexpectedly.

My Hyundai Sonata has encounter two failing cylinders (compression loss) due to scoring. When driving in the highway I got engine shudder and loss of power (speed) that could have put me in dangerous driving condition, accident or other. These GDI engines are notorious for poor oil circulation due to faulty designed piston rings. Hyundai has long history with these poorly manufactured engines and class action lawsuits. I notified Hyundai but they are not willing to remedy the situation. I have worked with local dealership Miller Hyundai, as well as corporate. All I get are excuses and that I’m not covered. These engines are completely problematic with oil consumption and oil blow by, causing seizing, rod bearing failure, carbon buildup, cylinder damage, etc. The info on the internet over customers and these GDI engines is overwhelming. Oil related Fires are another issue as well. Hyundai needs more accountability than the class action for rod baring failures. Because of the damage to my pistons, I could have gotten in accident with loss of power on highway…full due to poor piston rings, damage from improper oil flow and near complete engine failure.

I am reporting a safety-related engine failure involving my 2011 Hyundai Sonata 2.0T. In November 2025, at approximately 90,000 miles, the vehicle experienced a sudden engine failure while driving, including loss of power and abnormal engine noise. This created an unsafe driving condition and required the vehicle to be removed from service. Component/System Involved: The engine (Theta II 2.0T) suffered a catastrophic internal failure. The engine and internal components remain available for inspection upon request. Safety Risk: The sudden loss of engine power reduced my ability to maintain speed and maneuver in traffic, posing a safety risk to myself and other motorists. Confirmation and Inspection: The failure was confirmed by an authorized Hyundai dealership, which inspected the vehicle and documented the internal valve train condition through photographs. Hyundai Motor America reviewed the claim and issued a written denial. No independent third-party technical inspection was performed. Prior Symptoms: Before the failure, the vehicle had a history of excessive oil consumption requiring frequent monitoring and oil addition despite regular maintenance. Abnormal engine noise was present for approximately one minute before failure. No warning lights adequately predicted the sudden failure. Additional Context: This vehicle is equipped with a Theta II engine, which has been the subject of prior recalls and settlements related to internal engine defects. Hyundai denied warranty coverage alleging “exceptional maintenance neglect”; however, inspection photos show a well maintained valve train with no sludge or oil flow obstruction, only light surface varnish consistent with normal engine aging. I am concerned this failure represents a continuation of a known Theta II engine defect (confirmed by Hyundai technician who performed inspection with OBD code P1326 followed by engine failure) and poses a serious safety risk due to sudden loss of engine power while driving.

The vehicle experiences a recurring defect where the brake light turns on suddenly and the engine shuts off while driving. The failure appears related to the braking system (brake switch circuit), electrical system (CAN-bus/ECU communication), and engine control (shutdown/stall). The system remains installed and is available for inspection upon request. The shutdown poses a serious safety risk, including possible rear-end collision or loss of power in traffic. The problem has occurred multiple times. The dealership inspected the vehicle briefly but failed to diagnose or document the defect and returned the vehicle within hours, stating “it shouldn’t be a problem,” even though the issue continues. Hyundai has refused to provide recall documentation or authorize a re-inspection. The only warnings prior to shutoff are the sudden activation of the brake warning light just before the engine cuts off.

While driving home from work after 7 PM on the 215 NB freeway, the oil warning light suddenly illuminated, and the vehicle immediately lost engine power. Within seconds, the engine shut off completely, leaving me unable to accelerate or safely maneuver. I was forced to coast across lanes with no power, creating a significant risk of collision and nearly resulting in a rear-end accident. After the incident, I performed a crankshaft rotation test, which the engine failed, confirming that the crankshaft would not turn. I also verified that the timing chain remained intact. The vehicle has since been inspected by Hyundai technicians, who confirmed the engine failure under Service Campaign 953. Hyundai further communicated via email that my vehicle is eligible under the TXXI Theta Engine Settlement Agreement and expressed a willingness to discuss my recent engine concerns and the details of the settlement.

I am filing this complaint regarding a catastrophic engine failure in my 2011 Hyundai Sonata. According to Hyundai’s own documentation, Service Campaign 953, issued in 2018, was never performed on this vehicle. This campaign addresses the risk of connecting rod bearing failure caused by residual metal debris in the crankshaft oil passages.

Good day, please note that most of my communication with Hyundai has been over the phone. I sent one an email shortly after the event, and after following up on the phone, I received this following string separately. I can forward you more along the way, but Hyundai is in possession of the call recordings. I was hoping they would cover my repairs, my engine had a lifetime warranty, but during this process I learned that there was a recall for this car that I was never aware of as the new owner. I needed a software update to get any repairs covered. Please reach out to me for more info!

In summer of 2023 my car 2011 Sonata Hybrid quit running and would not start. My granddaughter had used the car to go to Oklahoma City for a tennis tournament. Her life was at risk because she was coming back in the evening and was alone. The next day I had the car towed to Ada Oklahoma and then called dealership and had it towed to Ardmore, Oklahoma where I had purchased the car new in 2011. The car was at the dealership for 6 months. The vehicle was inspected at the dealership. There were no warning lights or symptoms of the failure prior to the breakdown. I am an 80 year old female that knows nothing about a car engine and they talked to me like I was a mechanic. I still do not know why my claim was denied but was told that I did not have a claim. I had to rent a car to get to work for several months and was out the money to have my car towed 2 times. Not to mention the strain of being without my car for 6-7 months. I finally just gave up until I read about all these other people having trouble with Hyundai also.

I bought this car from someone in April of 2024 and the person who i bought it from said everything was perfectly fine, they brought it to the Hyundai dealership and according to the mechanic there the engine was fine….i have taken care of the engine since i bought the car, kept up with oil changes and everything….until a few days ago when the whole thing ceased up on me while driving down the road to my sons school. I wasnt going fast either, the speed limit is 40mph where i was when it happened, but I’m glad i have quick reflexes because otherwise we would have wrecked the car. Everything shut off on me and now its knocking. There is alot of metal shavings in my oil and my mechanic tried to drain it a few times to get the debris out of the oil but it does no good.

My daughter was driving her 2011 Hyundai Sonata on the freeway at 65mph when the engine light came on and car simultaneously slowed to a stop on 8/21/25 creating significant danger to my daughter and other drivers on the road. There were no prior warnings or indications, and car just had an engine check performed in June 2025. Had it towed to Hyundai on 8/22/25 and Hyundai completed an engine check and it failed. Hyundai told us they'd cover it under the extended warranty if only we could provide complete maintenance records. We were unable to satisfy their record request threshold, as we are not the only owners of this 14-year-old vehicle, so they've requested $10,000 to replace the engine instead. The 2011 Hyundai Sonata is part of the Theta II engine family that has been subject to multiple recalls, class-action lawsuits, and federal investigations due to catastrophic engine failures.

There was a 2011 Hyundai Sonata Hybrid transmission-related shift cable recall, Campaign 123, which covered certain 2011-2014 Sonatas (including some 2011-2015 Hybrids). The recall addressed the potential for the transmission shift cable to detach from the shift lever pin, which could prevent the car from being fully in park and potentially lead to rollaway

The affected component is the engine/rod bearing (Theta II 2.4L). My 2011 Hyundai Sonata stalled and the engine locked up twice in live traffic (March 2025 and July 2025). The vehicle is available for inspection if needed. This created a serious safety risk to me and others on the road, as the stall occurred on [XXX] at highway speeds. This failure could have been catastrophic had it happened on the DC/Baltimore Beltway or another high-traffic roadway. Hyundai’s system shows Recall 132 was marked complete at very low mileage (around 32,000 miles), but my vehicle later developed oil consumption and stalling consistent with rod bearing failure. Capitol Heights Hyundai noted a warranty pre-authorization (PA) in March 2025 and told me Hyundai needed my mailing address “for the claim,” but later said it was a typo and that no record exists. The dealership charged me for a diagnostic but did not inspect the vehicle for rod bearing failure, despite symptoms consistent with Recall 132. Annapolis Hyundai, where the car was purchased as a CPO, has admitted they have no documentation that Recall 132 was ever performed (no repair order, mileage, or technician notes). Yet Hyundai’s system shows Recall 132 marked “complete.” Without proof that the KSDS software or bearing inspection was done, I belive this recall should be considered open. Hyundai Consumer Affairs has stated that I must pay for towing and diagnosis before they will investigate, with possible reimbursement later. This conflicts with federal law (49 U.S.C. § 30120), which requires recall diagnosis and repair at no cost to the consumer. Prior to the failures, my vehicle had a history of oil consumption and “no oil on dipstick” findings, which are known precursors to rod bearing failure. No warning lamps appeared before the stalls. I am requesting NHTSA’s assistance in requiring Hyundai to provide documentation or reopen Recall 132 and perform a no-cost inspection/repair to ensure this vehicle is safe to operate INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am the proud owner of a 2011 Hyundai Sonata this is my 3rd sonata; we love it due to the worry free long last and warranty. Never had any issues through the years until last night ([XXX]). When getting off from work 6:15PM heading home for about 30 mins. I was driving my car approximately 35 mph when I went to turn a corner suddenly, my car started sputtering, knocking sound and failed to accelerate having traffic behind me not to cause an accident I put my hazard flashers on, and I lean over to the right on grass. Puzzled and scared saying to myself “ What the Hecks” what’s going on. The car parked on the side was having hard time staying on and shut down. I then went and opened the hood to check to make sure nothing was in my engine causing it, everything looked normal except, the smell of oil has a burnt smell to it which means in technical terms it has thrown a rod and bent valves and smell of burned electric. Finally, we called AAA, they advised their busy and it will be about 2 hrs. So, I sat there to wait for AAA. As I sat in my car waiting, I started researching online. I currently do not have any recalls or ever got any notice. I came across there is an active class action lawsuit going on for the rod bearing going out in these models and years. After some time, I called AAA back to get an ETA, they told us they were extremely busy, it would be about another 45 mins. At that time another tow company pulled up and asked if we needed a tow, we didn’t want to wait longer for AAA to get home so decided to have it towed home … totally cost $175. Today I am trying to contact Hyundai to see what we going to do regarding my car and praying it can get fixed on this recall that I had no idea and thanks God, I turned it off my car could start a fire & burned up. I never got notice about recalls for my engine and It’s sad Hyundai does contact owners ahead to let them know about this problem, think about it we are talking about lives.

1. The car began to randomly stall and stop running. This happened while driving and it was extremely dangerous. Typically, the engine would restart after at least waiting 15 minutes. Any attempt to start the car before that time would fail. 2. When the stalls happened, the car acted as if it had run out of gas. The engine would simply stop running WITHOUT WARNING, at intersections, on city streets, and on the freeway at high speed. It did not matter how full the gas tank was. 3. My brother and I diagnosed the problem as intermittent loss of fuel pressure. 4. My brother and I replaced the FACTORY fuel pump, and to hour horror, when we unplugged the electrical connection/plug, one of the pins from the fuel pump came out with the plug/connector. 5. We inspected the fuel pump and discovered that parts of the electrical plug INSIDE THE FUEL TANK had become burned and melted. See Image SANY0135.JPG === This is a SAFETY DEFECT - either the internal fuel pump electrical connections were faulty from the factory or the problem developed over time. There have been other recalls for this model of car for random engine stalls but this is a NEW and DIFFERENT cause. A dealer with a relatively inexpensive Infrared camera could likely spot this problem with minimal vehicle disassembly. There was clearly a LOT of heat concentrated in the area of the electrical connection to the fuel pump. We hope this report triggers a recall and prevents extremely dangerous random loss of engine power events, fires, or worse. Please recall all the vehicles that used that fuel pump for inspection before there is a disaster.

Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Risk: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.

Hyundai Motor Company (Hyundai) is recalling certain model year 2011 Sonata vehicles manufactured from December 11, 2009, through September 1, 2010. The affected vehicles may experience a brake fluid leak from the two brake lines that connect the brake system's master cylinder to the Hydraulic Electronic Control Unit (HECU) due to insufficient seal between the inner brake hose and metal brake line fitting.
Risk: If the brake lines leak brake sufficient fluid, the brake warning lamp in the instrument cluster will illuminate and longer stopping distance will be required, increasing the risk of a vehicle crash.
Remedy: Hyundai will notify owners, and dealers will replace the brake hoses with a revised service part, free of charge. The recall began in September 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 122.

Hyundai Motor Company (Hyundai) is recalling certain model year 2011-2014 Sonata vehicles manufactured December 11, 2009, through May 29, 2014. In the affected vehicles, the transmission shift cable may detach from from the shift lever pin.
Risk: If the transmission shift cable detaches, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver parks the vehicle, despite selecting the 'PARK' position, the transmission may not be in 'PARK.' If the vehicle is not in the 'PARK' position and the parking brake is not applied, there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Remedy: Hyundai will notify owners, and dealers will inspect and, as necessary, repair the connection between the shift cable and shift lever, free of charge. The recall began in September 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 123.

Hyundai Motor America (Hyundai) is recalling certain model 2011-2012 Sonata vehicles. The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released.
Risk: If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to rearward following vehicles that the vehicle is slowing or stopping. Additionally, if the brake switch plunger is not retracted, then the transmission can be shifted out of PARK without depressing the brake pedal. Either condition increases the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the brake pedal stopper pad with an improved part, free of charge. The recall began on January 6, 2016. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 136.

Investigations
8 NHTSA investigations on record
Investigations are agency reviews, not findings that a vehicle is defective.
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
On March 29, 2019, the Office of Defects Investigation (ODI) opened two Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) to broadly investigate incidents of non-crash fires (regardless of origin or operational status of the vehicle) on various model year Hyundai and Kia vehicles. During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types. The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine replacement. Additionally, both manufacturers have been installing an engine control software modification known as Knock Sensor Detection Software (KSDS) which is intended to detect impending engine failure, alert the driver, and limit engine power (to lessen likelihood of engine failure).KSDS is being installed under recalls and non-safety field actions, and both companies have extended limited engine warranties (see recall files). On December 22, 2021, ODI upgraded PE19-003 and PE19-004 to this Engineering Analysis (EA21-003, covering both Hyundai and Kia) to evaluate the scope of the prior recalls related to engine failures/fires and the efficacy of the recall remedies for the recalls, as well as the long-term viability of related programs and non-safety field actions being conducted by Hyundai and Kia. The former issue involved approximately 550,000 MY 2013 Hyundai Elantra, MY 2011 Kia Sorento, and MY 2012-2015 Kia Rio. The latter issue involved approximately 2.5 million recalled vehicles, which have been identified as displaying potential remedy concerns: Hyundai recalls 15V-568, 17V-226, 20V-746, and 21V-727; and Kia recalls 17V-224, 19V-120, 20V-750, and 21V-844. Regarding the recall scope issue, among all of the scope vehicles identified at EA opening, ODI found only the MY 2011 Kia Sorento vehicles equipped with both the Theta II 2.4L 4-cylinder Multi-Point Injection (MPI) and the Lambda II 3.5L 6-cylinder MPI engines experienced relatively high rates of reported fires. In December 2023, Kia issued recall 23V-877 that will cover about 80,000 MY 2011 Kia Sorento vehicles equipped with the Theta II 2.4L MPI engines. The remedy will involve an inspection, and if necessary, a replacement of the engine, as well as the installation of KSDS. It should be noted that in 2021 these vehicles were included in a KSDS product improvement campaign with warranty extension. For the MY 2011 Sorento vehicles equipped with the Lambda II 3.5L engines, ODI believes that future engine failures/fires involving these vehicles will likely be due to a lax in adhering to the proper or scheduled engine maintenance (regular engine oil changes), rather than a design or manufacturing engine issue. Regarding the issue of the efficacy of the recall remedies, ODI found the majority of the recalled Hyundai and Kia vehicles, by model, experienced lower reported fire rates after the remedies were applied. Furthermore, ODI found that for most vehicles that did not receive the recall remedies, by model, experienced relatively high fire rates. To address this problem, Hyundai informed ODI in December 2023, that it will renotify all of its owners covered by the Hyundai recalls of engine failures/fires every 8 months for the next 3 years. In December 2023, Kia stated that it will renotify the majority of its owners every 8 months for the next 3 years.Several previously recalled Kia models are excluded from the renotification due to their lower reported rates of engine fires. Overall, the renotification actions will help to increase the recall completion rates, thus reduce the frequency of engine fires in the future. In view of the recall action being taken by Kia and renotification actions being taken by both Kia and Hyundai, ODI is closing this Engineering Analysis. Also, both companies have been released from the 2020-iniated Consent Orders (Kia since November 2022 and Hyundai since November 2023). The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.
During this Preliminary Evaluation (PE), the Office of Defects Investigation (ODI) assessed the scope, frequency and potential safety-related consequences of non-crash vehicle fires caused by both engine failures and failures of other vehicle systems/components in model year (MY) 2011-2014 Hyundai Sonata and Santa Fe vehicles equipped with Theta II and Lambda II engines (approximately 1.3 million vehicles). ODI also reviewed field data of other Hyundai vehicles equipped with Theta II, Gamma, Nu and Lambda engines (approximately 4.8 million). As a result of this PE, Hyundai has issued NHTSA Recalls 20V-746 and 21V-727 to address potential engine failures and fires in certain Hyundai vehicles equipped with various engine types. Additional information on these and other related recall actions is available in the downloadable version of this resume available at NHTSA.gov. In addition, ODI has upgraded this PE to an Engineering Analysis (EA) 21-003 which will focus on potential recall scope concerns and recall remedy concerns related to the engine failure rewlated recalls mentioned above and conducted previously. See the EA21-003 Opening Resume available at NHTSA.gov for more information. Also available in the downloadable version of this resume is a list of the reference numbers for the 302 ODI reports, or Vehicle Owner Questionnaires (VOQs), cited above which ODI received through mid-November 2021. Note that the Manufacturer reports cited above are customer complaints received through March 2019.
In a letter dated June 11, 2018, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a safety defect investigation into non-collision related fires on model year (MY) 2011-2014 Kia Optima and Sorento, and Hyundai Sonata and Santa Fe vehicles. In a letter dated July 24, 2018, CAS requested that MY 2010-2015 Kia Soul vehicles be added to the petition. CAS stated that there is a higher number of complaints to NHTSA regarding non-crash fires on these vehicles compared to other similar vehicles. The Office of Defects Investigation (ODI) had already opened Recall Queries (RQ17-003 and RQ17-004) on all Kia and Hyundai vehicles equipped with Theta II engines for engine failures that may cause stalling and fires.The queries cover most of the petition subject Optima, Sorento, Sonata, and Santa Fe vehicles but not any of the subject Soul vehicles.On August 21, 2018, ODI opened a Defect Petition (DP18-003) to evaluate whether to grant or deny the CAS petition. ODI sent Information Request letters to Kia and Hyundai (September and October 2018) requesting information on all engine and non-engine related fires in the petition vehicles.ODI performed extensive analysis on the information obtained from Kia and Hyundai. During the DP18-003 analysis, Kia and Hyundai each initiated three additional safety recalls related to engine compartment fires on certain petitioned and non-petitioned vehicles (nearly 740,000 total vehicles: Recalls 18V-907, 18V-934, 19V-101, 19V-063, 19V-120, and 19V-204). Based on ODI?s review of the applicable materials, including responses to Information Requests sent to multiple manufacturers, Vehicle Owner Questionnaires (VOQ), and Early Warning Data, NHTSA decided to grant the petition.The CAS petition was granted on March 29, 2019. Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) have been opened to assess the scope, frequency, and potential safety-related consequences of alleged defects relating to non-collision vehicle fires in the 2011-2014 Kia Optima and Sorento, 2011-2014 Hyundai Sonata and Santa Fe, and 2010-2015 Kia Soul.Attached is a list of the reference numbers for the 404 VOQs cited above.
The Office of Defects Investigation (ODI) opened PE18-003 on 3/16/18 to investigate incidents involving crashes, resulting in significant collision related damage, where the frontal airbags failed to deploy. ODI reviewed complaint data, available design, test, and field data on the model year (MY) 2011 Hyundai Sonata, MY 2012-2013 Kia Forte and Forte Koup vehicles. ODI also evaluated data from the automotive air bag system supplier, ZF-TRW (ZF), to review vehicles that may contain the same air bag control unit (ACU) used in the subject vehicles. Hyundai Motor America (HMA) issued recall No. 18V-137 for MY 2011-2013 Sonata and MY 2012 Sonata Hybrid vehicles. Kia Motors America (KMA) issued recall No. 18V-363 for MY 2010-2013 Kia Forte and Forte Koup, MY 2011-2013 Optima, MY 2011-2012 Optima Hybrid, and MY2011-2012 Sedona vehicles. The two recalls address vehicles containing ACUs manufactured without adequate circuit protection by installing a wire harness filter kit to prevent internal damage to the ACU. In the event of a crash, ACU damage may result in the disablement of the vehicle's airbags. Each respective manufacturer has mailed letters to affected vehicle owners informing them of the remedy and its availability. ODI plans to evaluate the susceptibility of the subject ACU to electrical signals, as well as other vehicle factors that can either lead to, or reduce the likelihood of, an electrical overstress event in other vehicles manufactured with the subject ZF ACU.Accordingly, this Preliminary Evaluation has been upgraded to an Engineering Analysis (EA19-001), to expand the scope of the investigation to include the Tier-one supplier and any manufacturers who installed the subject ACU in production vehicles. Additional information is available with the closing resume available at NHTSA.gov (see Associated Documents).The ODI complaints cited above can be viewed at www.NHTSA.gov under the following ODI identification numbers: 10781050, 10849839, 11099038, 11080341.
NHTSA opened Recall Query (RQ) 17-004 to investigate the timeliness and scope of Hyundai?s Theta II GDI engine recalls (Recall Nos. 15V-568 and 17V-226), and Hyundai?s compliance with reporting requirements. On November 23, 2020, the Agency entered into a Consent Order with Hyundai to administratively resolve NHTSA?s assertions of violations of law in connection with RQ17-004. NHTSA?s assertions included that Hyundai may be liable for civil penalties on multiple grounds, including the untimeliness of Recall Nos. 15V-568 and 17V-226, inaccuracies in Hyundai?s recall reports, and that a required report describing potential safety-related issues contained certain inaccuracies or omissions.Under the Consent Order, Hyundai agreed to a total civil penalty of $140,000,000. The total civil penalty included payment of $54,000,000 as a Non-Deferred Amount. Hyundai also agreed to a sum of $46,000,000 as an Abeyance Amount to be deferred and held in abeyance pending its satisfactory completion, as reasonably determined by NHTSA, of the requirements of the Consent Order.Additionally, Hyundai agreed to a $40,000,000 Performance Obligation Amount to be expended by Hyundai to fulfill specified Safety Data Analytics Infrastructure obligations and Test and Inspection Laboratory obligations. The Consent Order also includes other terms designed to enhance Hyundai?s safety practices, and requires Hyundai to retain a Third-Party Auditor who directly reports to NHTSA.Other than RQ17-004, the Consent Order is not intended to affect any other current or future investigation which may involve vehicles equipped with Theta II GDI engines. In particular, Engineering Analysis (EA) 21-003 (which is upgraded from Preliminary Evaluation (PE) 19-003) continues NHTSA?s evaluation of certain performance and design issues relating to the Theta II and other engines.Nothing in the Consent Order discharges Hyundai from any obligation to comply with the Safety Act or regulations thereunder, including the obligation to carry out recalls in accordance with law, and to initiate a recall upon any future determination by Hyundai, or upon any finally adjudicated order from NHTSA, that vehicles equipped with Theta II GDI engines contain a defect related to motor vehicle safety or do not comply with an applicable FMVSS.This RQ is closed. Closure of this RQ has no bearing on the terms of the Consent Order, including Hyundai's ongoing performance obligations, and does not represent a determination by the agency as to Hyundai?s performance under the Consent Order to date.
The Office of Defects Investigation (ODI) is aware of 7 complaints and field reports and 10 warranty claims on the subject vehicles that allege the intermediate steering shaft became loose or in some cases separated from the upper steering column and/or the steering gearbox, causing (or potentially causing) the hand wheel to become mechanically de-coupled from the road wheels resulting in a complete loss of steering capability.The reported causes include excessive free play or separation of the intermediate steering shaft upper and/or lower universal joint cross shaft/yoke; missing, loose or damaged universal joint pinch bolts; improperly assembled intermediate steering shafts with misaligned splines or insufficient spline engagement preventing the universal joint pinch bolt from being secured in the retaining groove when fastened.On September 20, 2010, the manufacturer notified the agency that it would conduct a safety recall (NHTSA Recall No. 10V-426) to address the alleged defect in approximately 139,500 subject vehicles produced from December 11, 2009 through September 10, 2010.In addition to inspecting the steering shaft, the manufacturer will also update the electric power-assist steering control software to address complaints that the steering wheel vibrates or shakes as a result of a a motor driven power steering malfunction.The manufacturer began notifying affected owners by written letter on October 14, 2010.To date, 119,383 subject vehicles have been serviced under the recall campaign and 58 subject vehicles have received replacement parts as a result.Accordingly, this investigation is closed.
