Vehicle is a 2013 Hyundai Santa Fe Sport with the 2.4L Theta II GDI engine. A Hyundai dealer documented excessive oil consumption in December 2025 (3 quarts consumed over 1,703 miles during a dealer-administered oil consumption test; repair orders on file and available for inspection). On April 19, 2026, at 160,913 miles, following a highway drive, the engine developed a pronounced knock and vibration at low RPM and began stalling within seconds of idling in Park, with check engine and charging warning lamps illuminated. An engine that stalls at idle presents a safety hazard in traffic due to loss of power braking and steering assist. The vehicle was removed from service the same day, has not been driven since, and remains available for inspection. Knock Sensor Detection System software (Campaign 953) was installed and did not prevent the failure. Manufacturer has been notified in writing and consumer affairs cases are on file.

Issue was first identified in September 2024 when a rattling noise prompted inspection, and the engine was found to be significantly low on oil. Excessive engine oil consumption was confirmed with failure during manufacturer testing. Vehicle emits occasional burning oil smell when idling after 10 miles+ driving. Vehicle failed a 1,000-mile oil consumption test following a “Dynamic Engine Clean” performed by a certified independent mechanic, with documented oil loss of approximately 2 quarts. Vehicle subsequently failed a dealer-administered oil consumption test, with documented oil loss of approximately 2.3 quarts within 1,000 miles. Engine oil levels have dropped to critically low levels between checks despite active monitoring and maintenance. This condition presents a risk of engine seizure, sudden loss of power while driving, and potential engine compartment fire due to oil consumption or leakage. The issue has been reproduced and documented by both an independent mechanic and a Hyundai dealership. Despite confirmed excessive oil consumption, the manufacturer has delayed corrective action and has required repeated oil consumption testing and engine cleaning procedures rather than proceeding with repair. This condition appears consistent with known defects associated with Hyundai Theta II engines.

I have great concern that certain vehicles of Hyundai are getting a little bit of extended warranty occupant classification system forward slash occupant detection system known issues. OCS/ODS I will try to attach a picture of the letter. As a nurse manager I find this once again appalling on Hyundai behalf, after these years pass we won't know if our air big warning lights or trouble codes or even a a passenger is detected when driving. They offered to pay if you had issues with this problem or in my case in the next four and a half years they would cover it but after that do I feel that this is my problem because they're having defect sensors and warning lights or maybe lack thereof altogether after speaking to them when I called and made a case number XXX with Hyundai Motor America. I strongly believe this should be a recall. I would never trust anybody sitting in my passenger seat, and I don't think you would either. They always try and find some way to get around doing the right thing and obviously they have problems with intermittent airbags warning lights trouble codes and this needs to be looked into if there are any risk/issues detecting or possibly never detecting a grandchild sitting in that front seat! After 5 years I will worry if anybody sits in the front seat now. I have started the process and will wait for your reply, of communicating with [XXX] our Minnesota State Attorney General's office on this matter.

I noticed a Check Engine Light flashing on my dashboard while driving on May 27, 2026. The vehicle suddenly losing power is extremely unsafe for me and my family, and also others on the road. This is a repeated P1326 code which happened before in 2021 and 2024. Based on the receipts I have from the previous inspections from the dealer, the Bearing Clearance Test (BCT) was not done in 2024, but was performed in 2021. The knock sensor was replaced in 2024 and I was denied engine replacement. This is a repeat failure of the same condition under Hyundai Motors TSB T3G Theta II. Once again, my safety was at extreme risk as the engine lost its power suddenly. It could have easily lead to a crash. In 2024, Hyundai and the dealer declined an engine replacement despite me showing the safety concerns and my possible eligibility for an engine replacement for the underlying condition.

The contact owns a 2013 Hyundai Santa Fe Sport. The contact stated that occasionally, while driving at various speeds, an abnormal knocking sound was heard coming from under the hood while the accelerator pedal was depressed, and the steering wheel would shudder. The Check engine oil warning light illuminated. Upon further investigation, the contact related the failure to NHSTA Campaign: 17V226000 (Engine and Engine Cooling). The vehicle was taken to a local dealer, where it remains for further investigation; however, the vehicle was not diagnosed or repaired due to a lack of maintenance records, and the recall repairs were rejected. The manufacturer was made aware of the failure and determined that the recall repairs were performed under previous ownership; however, the recall repairs were not completed. The failure mileage was approximately 147,000.

I am reporting a serious safety defect involving my 2013 Hyundai Santa Fe Sport equipped with a Theta II engine While driving and exiting the freeway with my wife as a passenger, the engine suddenly failed after knocking symptoms and completely seized/locked while the vehicle was still in motion. The vehicle immediately lost motive power and came to a stop, creating an immediate and dangerous traffic safety hazard. Had this engine seizure occurred moments earlier while traveling at freeway speed, it could have caused a catastrophic accident involving serious injury or death. The Hyundai dealership diagnosed the vehicle with rod bearing failure, which is the known defect associated with Hyundai Theta II engine failures. My VIN falls under the Theta II extended engine warranty program, and the dealership confirmed eligibility and accepted the vehicle for inspection under that coverage. Despite this, Hyundai denied the repair claim, first alleging maintenance-related issues and later stating the vehicle was out of warranty. I maintain that the vehicle was properly maintained with oil changes performed approximately every 6,000/8,000 miles. Some calendar-time gaps occurred because the vehicle was stored and driven very little during my recovery from a personal injury surgery and recovery, but the vehicle was maintained on mileage intervals. This engine defect resulted in sudden engine seizure and total loss of motive power while driving, creating a serious safety risk to vehicle occupants and surrounding motorists. I am reporting this defect so it can be documented and investigated.

On [XXX] while entering the parking lot of my office, I noticed a blinking check engine light on the car's dashboard. I've never experienced this before so I called my husband. He asked me to use a diagnositic tool he kept in the car. I did and there was a code "P1326" when I pressed the key for more information it said something about the manufacturer. My husband told me to call the nearest dealer. I called Castle Hyundai in Downers Grove. I was instructed not to drive the care and have it towed to the dealership as soon as possible which I did. Castle Hyundai verified the P1326 code and fixed the knock sensor, changed the oil. I picked the car up on March 13. On [XXX], the flashing check engine light returned while driving home from work. Again, we used the diagnostic tool and again the code P1326 appeared. The car was towed back to Castle Hyundai. On Monday, I spoke with Christain Jones the service director because I hadn't heard anything about the car. He called later in the day and said that the car needed a new engine. He asked for records of my oil changes since purchasing the car in 2021. I emailed him three from 2022, 2023 and 2024, the four change was done by Castle on March 12 2026. I was told that he would send the the information to Hyundai regarding a new engine. However, he stated that he was not confident the company would approve the claim. This after, I received an email from Eric Marcum with Castle. The email stated that Hyundai denied the engine replacement due to "lack of maintenance". He wanted to know if we wanted an estimate on replacement of the engine. I responsed that I needed Hyundai's rejection in writing and I also wanted an estimate of the replacement. I attempted to contact Hyundai's Customer Care, however, their offices were closed until Monday. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While my vehicle was at an authorized Hyundai dealership for engine warranty repair, I reported a suspension grinding noise and requested that it be inspected. This concern was raised while the vehicle was in the dealership’s possession and was communicated as a safety concern. The engine repair was completed and the vehicle was returned to me. No inspection findings, documentation, or technician notes were provided addressing the suspension concern. The repair documentation I later received does not include any reference to the suspension issue or any inspection findings related to that concern. The dealership has also confirmed that no additional documentation exists beyond the repair order. After the vehicle was returned, warning lights appeared that were not present prior to the repair. A suspension grinding noise may indicate issues affecting steering, suspension, or vehicle stability. I am concerned that the vehicle was released without inspection or documentation of a reported safety related condition.

There has been a loss of oil meaning i have been adding oil in between oil changes at least once a week, there has been smoke coming from under the hood and if you run the heat or air you have to have circulate cabin air button pushed or it pulls the smell inside the car and it is overwhelming. The smoking has been going on for about at least a month now.

I was driving on March 20, 2026 at about 12:00 PM when I suddenly noticed smoke, a strong gasoline smell, an oil smell, and a burning odor coming from the vehicle. I pulled over immediately because I believed the vehicle was unsafe and at risk of fire. The vehicle had to be towed. An independent repair shop later found a fuel leak at the high-pressure fuel line / fuel pump area, a loose ground wire on the right-hand side of the engine, a valve cover gasket leak, and engine timing chain noise. I was informed that gasoline had sprayed throughout the engine bay. This created an immediate fire hazard even though no actual fire occurred. This problem was especially concerning because the vehicle had been inspected and serviced by an authorized Hyundai dealer in December 2025, less than about 3,000 miles earlier. The loose engine ground wire and fuel leak raise serious concerns about vehicle safety and the adequacy of the prior inspection. I contacted Hyundai the same day and reported this as a fire-risk safety issue, but I did not receive timely assistance. Because immediate dealer service was not available, I had to authorize emergency repairs at a local shop for safety reasons. No warning lights were noted before the incident. The failure was confirmed by the repair shop.

While traveling at approximately 80 mph on the highway, my vehicle suddenly lost all response to the accelerator pedal. Despite continued pressure on the gas, the vehicle rapidly decelerated to approximately 40 mph on its own. There were no warning lights, unusual noises, or physical indicators of a problem before, during, or after the event. I was able to safely navigate the vehicle off the highway. The vehicle appeared to operate normally afterward. The following day, I brought the vehicle to a mechanic who was unable to replicate the issue and found no stored fault codes. No repairs were made. Given the known concerns surrounding the Theta II engine in this model year, I am submitting this incident for documentation purposes and to contribute to any ongoing or future investigation into sudden acceleration loss in 2013 Hyundai Santa Fe vehicles.

Day 1 – Feb 11 at 4pm incident occurred my daughter was driving the vehicle on [XXX] , she was in the far right hand lane preparing to take an upcoming exit. Suddenly and unexpectedly the hood opened obstructing her view of the roadway and smashed the front windshield. Because she was in the right hand lane she was able to pull the vehicle to to the shoulder of the road immediately. No other vehicles were involved because of both her location (right hand lane) and ability to access the shoulder immediately. She could have been killed! The problem has not been confirmed Hyundai has informed me it will take 5/6 weeks to determine if an inspection is warranted. -Thursday February 19 We got the vehicle to the closest Hyundai dealer Metro West in Framingham Massachusetts on Thursday February 19 - I explained to the service representative the history (recall and repair in 2017) and a request to investigate recurrence of the recall defect as well as to prepare an estimate for repair. I never received a phone back so I called them on Wednesday February 27 and was informed that the vehicle estimate and inspection was in progress. At that point I contacted Hyundai corporate offices and was given a case number. On March 3, I called again and completed the preliminary investigation report - i was informed they would get back to me in approximately 48 hours. - On 3/9/26 after a phone conversation I was emailed a request to inspect my vehicle authorization form and another form (11 questions that had been answer numerous time by phone already) both were completed and submitted the following day 3/10/26. Dealership now threatening storage fees - Because the vehicle experienced failure of a component that was previously repaired under a federal safety recall, I am formally requesting that Hyundai preserve all evidence relating to the hood latch assembly and related components for purposes of regulatory review and potential insurance subrogation.

I requested Engine oil consumption tests on November 12, 2020 and March 27,2021 at Vandergriff Huyndai, Arlington, Tx. Nothing was resolved,. I have been adding oil myself and getting oil changes regularly since. At 146,000 miles it's been worse. After just 2,000 miles after an oil change it was below low, my mechanic topped it off 3 weeks ago and I've had to add oil since. Took my car to Jerry's Huyndai, Weatherford, Texas on December 29,2025. Due to oil consumption, smoke, smell, and I'm wondering if the vibrating is from the engine or if I need new spark plugs. I was told that my valve cover gasket needs to be replaced. I feel like I'm still getting the run around and the car can't keep oil above low level. I've never seen oil under the car and when i took the car to Vandergriff in 2020 and 2021 they didn't see a leak they said. I also took my car in 8/21 and had the ABS repaired and as of recent its out again. I took my car into an independent mechanic shop today 1/2/2026 and he said he felt that the valve cover gasket is not the main problem he feels it would be a waste of money until the engine is replaced. I also heard a new noise today not knocking but tapping noise while driving. My car has hesitated recently, but Jerrys huyndai didnt have that happen while driving it. My car would be available for inspection any time requested. I am just concerned about the smoking if it will get worse, is there a risk of fire and I'm disabled, so I'm concerned if I will have a problem getting out of the car in time if that were to happen or if the car would stop in the middle of the street. This is my only car and I care for 2 sons that are disabled. I need a safe car. Also, the car manager Rachel at Jerry's Huyndai seemed focused that I would be charged 225.00 if it was not the rod bearings. It just seemed like she more focused on that instead of finding the problem. The only lights on is the ABS.

On Aug 2, 2025, while traveling back from vacation with our family of 4, our engine failed and completely seized up on a very busy highway. The vehicle completely shut off in a lane of travel near an exit ramp, and we were unable to even pull off on a shoulder for safety. We were unable to restart the vehicle or reproduce the issue because the vehicle will not turn on. There were no warning lamps or other messages. However, the car has historically consumed an extraordinary amount of oil, even with routine oil changes and service. Two quarts of oil were added to the vehicle the day before this happened. The vehicle was towed to a Hyundai dealership and the incident was reported to Hyundai USA. We've been told the dealership can not run tests or inspect the vehicle until Aug. 21, nearly three weeks after it happened. We were told this is because they have numerous other vehicles with similar problems. This was an incredibly terrifying experience that put the safety of our family of 4, including two young children, at risk. A bystander called 911 and a state trooper arrived to set up flares and expedite a tow truck. We were told the spot we broke down is an incredibly busy part of an interstate where fatal accidents happen every other day.

While driving, my 2013 Hyundai Santa Fe suddenly began losing acceleration without warning. No check engine lights were on at the time. The RPMs surged to 5,000–6,000, but the vehicle failed to gain speed. Moments later, the car lost all power completely. The red engine warning light and battery light illuminated on the dashboard, and the vehicle became unresponsive and would not restart. I had the vehicle towed to a certified Hyundai dealership, where a diagnostic inspection confirmed a rod bearing failure — a well-documented issue associated with the Theta II engine. The dealership initially stated this type of failure should fall under Hyundai’s extended warranty related to the class action lawsuit regarding defective Theta II engines. I purchased the vehicle used in 2020 and have kept detailed maintenance records for every year of ownership, all of which I submitted to Hyundai in support of my engine replacement claim. Despite this, Hyundai denied coverage and declined to replace the engine. This type of sudden engine failure, without any prior warning indicators, is extremely dangerous and appears consistent with the known defects in Theta II engines previously investigated by NHTSA. I’m filing this complaint in the interest of safety, transparency, and accountability, especially as other drivers may be exposed to similar risks. I respectfully urge NHTSA to review this incident as part of its ongoing oversight of Hyundai’s Theta II engine defects and consider re-opening or expanding its investigation into these failures. I also request that NHTSA encourage Hyundai to reconsider its decision to deny my engine replacement claim, especially given the safety-critical nature of the failure and my full compliance with maintenance expectations.

While I acknowledge that my vehicle is no longer under warranty, I remain extremely concerned about the excessive oil consumption issue. My vehicle is equipped with the Theta II engine, which has been the subject of multiple class action lawsuits and recalls due to serious engine defects, including excessive oil consumption and internal engine failure. To be clear, I have already had the vehicle inspected by a non-Hyundai dealership, which confirmed there are no external oil leaks. This indicates the issue is likely internal and consistent with the known defects associated with the Theta II engine. Given Hyundai’s awareness of these problems — as reflected in class action settlements and technical service bulletins — I believe it is reasonable to expect Hyundai to cover the cost of diagnostic inspection and consider goodwill assistance if a defect is confirmed. Hyundai got back to me but and said We have reviewed your vehicle information and have determined your vehicle is affected by Campaign TXX8. However it’s over the 150000 miles

While driving at highway speeds (approximately 70 mph), my 2013 Hyundai Santa Fe Sport suddenly lost power and began shaking violently. I was forced to quickly maneuver across multiple lanes of traffic to exit the freeway and avoid a potential collision. The vehicle became barely drivable and extremely unsafe, especially at high speed. Hyundai later diagnosed the issue as a complete engine failure due to zero compression in cylinder 2. This catastrophic failure happened without warning lights, abnormal noises, or prior symptoms, making it a severe and unexpected safety hazard. Had this occurred while merging, on a curve, or in heavy traffic, it could have easily led to an accident, injuries, or worse. This type of failure — sudden loss of propulsion at freeway speed — puts both the driver and others on the road at serious risk. I am submitting this report because I believe this engine failure reflects a critical mechanical defect that warrants investigation.

The engine completely failed while I was driving. This is the second engine failure I’ve experienced with this vehicle. My first engine blew at 100,000 miles, and despite having a warranty, Hyundai refused to cover it. In a panic, I had to deplete my savings to buy a replacement engine, which only lasted six months before failing again. Hyundai still refuses to cover the second failure. The failed engine may still be available for inspection if needed. I was driving on the highway with both of my children when the engine completely shut off in the middle of the road. This left us stranded in a dangerous situation with speeding cars all around us. A sudden engine failure at high speeds could have caused a major accident, risking my life, my children’s lives, and other drivers' safety. The failure was confirmed by a service center, but Hyundai refuses to take responsibility for the defect or provide coverage under my warranty. The vehicle has been inspected by a service center, but Hyundai has refused to inspect or assist in any way. There were no warning lamps or messages before the engine shut down. The failure was sudden and unexpected, leaving me in a life-threatening situation on the highway.
