2014 Hyundai Sonata

I am submitting this complaint because I believe this issue presents a serious safety concern. My 2014 Hyundai Sonata experienced a failure related to the steering angle sensor, causing the ESC, ABS, and traction control warning lights to illuminate while driving. As a result, these important safety systems lost functionality and were no longer available to assist in maintaining vehicle stability and traction during normal driving conditions. This failure occurred without warning and required replacement of the steering angle sensor, followed by a required calibration. A critical steering-related component should not fail under normal driving conditions, especially when its failure can disable multiple electronic safety systems. Drivers may not immediately realize that these systems are no longer functioning, increasing the potential risk during emergency maneuvers, wet road conditions, or sudden avoidance situations. While researching this issue, I found that many other Hyundai owners have reported similar steering and electronic stability control problems. I respectfully request that NHTSA investigate whether steering angle sensor failures, related steering system components, or the associated calibration requirements represent a widespread defect affecting 2011–2014 Hyundai Sonata vehicles. If this issue is determined to be common, I ask that Hyundai be required to address the defect through an appropriate recall or extended warranty program so owners are not responsible for repairs involving a critical vehicle safety system.

Updated NHTSA Complaint DraftVehicle Information: 2014 Hyundai SonataVIN: [XXX] Incident Date: XXX Description of Safety Defect:While driving on XXX, the vehicle's engine experienced a catastrophic mechanical failure and completely shut off without warning, causing an immediate loss of motive power. This sudden engine stall created an extreme, hazardous traffic safety risk.A subsequent professional inspection revealed that the vehicle's odometer had been illegally rolled back and tampered with by the selling dealership (Johny's Auto Center in 120 bleu hill ave Roxbury, MA) 02119 prior to purchase. The true, undocumented mileage of the engine is significantly higher than indicated, directly causing this sudden component failure. I am reporting this incident both as a critical vehicle safety defect and as a case of illegal odometer fraud.

I am submitting this complaint regarding a serious safety issue involving my Hyundai Sonata. While driving under normal conditions, my vehicle suddenly entered a low-power ("limp") mode without warning. The vehicle would not accelerate beyond approximately 30–35 mph, creating a potentially hazardous situation in traffic. At the same time, the check engine light began blinking. The sudden loss of power significantly reduced my ability to maintain traffic speed and safely maneuver the vehicle. This condition could have increased the risk of a rear-end collision or other accident. I brought the vehicle to an authorized Hyundai dealership (Fred Beans Honda Of Abington PH# 215-392-9020) for diagnosis. The dealership confirmed that the vehicle stored Diagnostic Trouble Code (DTC) P1326, related to the Knock Sensor Detection System (KSDS). According to the dealership, the vehicle entered limp mode as a result of this fault. The abrupt reduction in vehicle power and speed occurred without sufficient warning and created a safety concern. I am reporting this incident so that NHTSA can investigate whether this condition represents a broader safety defect affecting Hyundai Sonata vehicles equipped with the KSDS system. Vehicle Information: Make: Hyundai Model: Sonata Model Year: 2014 I request that NHTSA review this issue and evaluate whether additional action is warranted regarding vehicles experiencing DTC P1326 and associated limp-mode operation.

Vehicle Information: Year/Make/Model: 2014 Hyundai Sonata Mileage: less than 120,000 miles Ownership: Second owner Complaint: I am filing a complaint regarding a serious engine failure in my 2014 Hyundai Sonata. My vehicle experienced issues beginning with a faulty knock sensor, which escalated into complete engine failure. This issue appears to be identical to problems that have already been identified in recalls involving similar Hyundai Sonata models. Despite experiencing the same symptoms and failure pattern, my specific VIN is not included in the recall. My vehicle has been well maintained, has under 120,000 miles, and should not have experienced a total engine failure under normal conditions. Based on the known recall issues related to engine defects and knock sensor failures, I believe my vehicle is affected by the same underlying defect. I am concerned that vehicles like mine are being excluded from the recall despite having identical safety-related issues. Engine failure while driving presents a serious safety risk, including potential loss of power, stalling, or inability to accelerate in traffic. I have had the car looked by a professional and advised of the engine failure and this is a common issue with this make and model.

ABS module/brakes system goes into limp mode randomly, which causes brake malfunction, throwing codes c1233, c1234 and c1236. There was a recall repair performed by Hyundai about two years ago, however there was two options on NHTSA recall 23V651000/campaign 251. One was to replace a safety plug fuse issue, TSB 23-01-054H . That is the recall they performed. The other recall repair which they did not perform is to replace the ABS module. The Hyundai dealer says I must pay a $225 diagnostic fee for them established they need to do this recall repair . Does that sound correct to you?

While driving with my family on a busy freeway at approximately 70 mph, our vehicle suddenly displayed a loud, urgent warning: “Hybrid System Warning – Safely Stop and Do Not Drive!” At the same moment, the car lost the ability to accelerate without any prior signs of trouble. We were extremely fortunate to have enough momentum to coast to the shoulder and shut the vehicle off, unsure of how serious the issue might be. Being stranded without warning on a high‑speed highway put my entire family in a dangerous situation. After a few minutes, we restarted the car to see if we could at least get it off the freeway. The warning had disappeared, and the vehicle drove normally, allowing us to take back roads home. The lack of any prior symptoms makes this even more concerning. Losing acceleration at highway speeds with no warning is a major safety hazard. We took the vehicle to a dealership immediately, but because the warning light was no longer active, they were unable to diagnose the problem. A few days later, the same warning appeared again—this time only a couple minutes from home. I turned around immediately for safety, parked the car, and once again the warning disappeared as soon as the vehicle was shut off. At this point, we have a car sitting in our driveway that we do not feel safe driving. The dealership cannot identify or repair the issue unless the warning is active, & even then, they cannot guarantee that a diagnostic code will appear. After researching this problem online, it’s clear that many other Hyundai owners are experiencing the same issue, often spending thousands of dollars without a definitive fix. Despite how common & dangerous this problem appears to be, there are no recalls & no consistent guidance from dealerships. This situation is unacceptable from a safety standpoint. A vehicle that can suddenly lose power at highway speeds—with no warning and no reliable way to diagnose the cause—poses a serious risk to EVERYONE and needs to be investigated

The engine failed in my 2014 Hyundai Sonata for the 2nd time while driving in evening traffic on a major interstate with my elderly father in the car with me. The engine completely shut down while in mid drive on the interstate with no power. The engine and oil lamp indicators immediately came on right before the engine lost power on the interstate. This caused my safety and the safety of my father to be put at risk by not being able to have any power while in the lane of evening traffic. My vehicle was towed to the nearby Hyundai dealership, Modern Hyundai of Concord, where their service department conducted inspection of the engine issue and where it was kept for 4 months with no repairs made per the orders of Hyundai Motor America. Hyundai Motor America refused to honor their own warranty to replace the engine (engine in need of replacement for the 2nd time).

My vehicle, a 2014 Hyundai Sonata Turbo, is having brake lock-up issues. It seems to be related to the AVS (Automatic Brake System). This happens mostly when the vehicle is parked on a hill and the brakes lock up when I start moving. This has been happening for several months, but my mechanic hasn't been able to find the problem. I made an appointment with Hyundai to find out what the issue is, but they told me there's no recall related to it.

I was driving my 2014 Hyundai Sonata in a rural area when smoke suddenly entered the cabin from the engine compartment. Two bystanders waved me down, alerting me that they could see fire underneath the engine compartment. I immediately stopped the vehicle, turned it off, and exited safely. I attempted to contact 911, but reception was poor. The fire spread from the engine compartment and engulfed the vehicle, producing thick smoke that created a serious safety risk. Emergency services arrived approximately 15 minutes after being notified and extinguished the fire. The vehicle burned for approximately 30 minutes in total resulting in total loss. There were no warning lights or messages prior to the fire. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives beyond the fire report. It was towed and is being stored on private property awaiting investigation.

The vehicle experienced a sudden engine failure and loss of power while traveling at freeway speed. Two days earlier, the vehicle had been taken to an authorized dealership for factory recall service. During that visit, concerns were raised about known engine issues associated with this model, but the vehicle was returned to service. While driving on the freeway, the engine abruptly stalled without warning, causing immediate loss of propulsion and power. This created a dangerous situation in moving traffic, requiring rapid maneuvering to avoid a collision and safely exit traffic lanes. The vehicle became inoperable and could not be restarted. The failed component appears to be the engine or related internal engine system. The vehicle was towed back to the dealership following the incident and has remained inoperable since that time. The vehicle is currently available for inspection. The failure placed the driver at significant risk due to the sudden loss of power at highway speed. No collision occurred, but the risk of serious injury or death was present. The problem has not been reproduced because the vehicle has remained disabled since the incident. The dealership and manufacturer have inspected the vehicle after the failure. The manufacturer is reviewing the incident under an internal process. There were no prior warning lights, messages, or symptoms indicating imminent engine failure before the stall. The failure occurred suddenly and without advance notice.

My 2014 Hyundai Sonata experienced a P1326 engine fault code, which activates the knock sensor system due to engine bearing wear. This condition is directly related to Hyundai’s safety recall 17V226 (Theta II engine). The Hyundai dealership submitted my case to Hyundai corporate, and Hyundai denied the repair solely because my vehicle has over 150,000 miles. A manufacturer cannot refuse a federal recall repair due to mileage, and Hyundai’s engine recall has no mileage or time limit. The denial places me in an unsafe situation, as the recall defect can cause engine seizure or stalling while driving. I am requesting NHTSA intervention.

The High-Voltage (HV) Hybrid Battery Pack Assembly failed, resulting in a system shutdown and the required replacement. The primary code is DTC P0A80 ("Replace Hybrid Battery Pack"), which indicates an internal manufacturing or design flaw, specifically a weak battery module or compromised internal connection, not normal wear. The defective component (the high-voltage battery) is currently at and is available for inspection. The entire vehicle is also compromised by the Anti-Lock Brake System (ABS) Module defect (NHTSA Recall 23V-651000). My safety was put at risk in two primary ways: 1. Immediate Loss of Power: The hybrid system failure resulted in a loss of drivetrain power, rendering the vehicle nearly immobile. This occurred on at approximately mph, placing me at high risk of a collision. 2. Latent Fire Risk: My vehicle is covered under the NHTSA ID 23V-651000 fire risk recall due to the ABS module. Hyundai specifically advised owners of these vehicles to "park their vehicles outside and away from structures" until the remedy is complete, confirming the severity of the latent fire hazard. The failure of the secondary HV battery system occurred within this already dangerous, electrically unstable environment. Yes, the vehicle was inspected by the Hyundai dealership / independent shop at the time of failure.. The manufacturer's corporate division has been contacted and is aware of the defect and the resulting $10,000 replacement estimate, as they offered a 50% "goodwill" subsidy which I am rejecting, asserting 100% coverage is required for a defect. Yes. The primary preceding warning was the intermittent appearance of the "Check Hybrid System, Turn off engine" warning.

Hello, I brought my 2014 Hyundai Sonata (approx. 73,000 miles) to an authorized Hyundai dealership (MotorWorld Hyundai, Wilkes-Barre, PA) on August 4, 2025, for Recall 162 (NHTSA 17V-226) due to audible engine knocking. I reported the noise when dropping off the vehicle. The dealer claimed the engine passed the inspection but did not provide any documentation confirming that the required bearing test was performed. They said the issue might be from the top of the engine (possibly the timing chain) and wanted to charge $800 to disassemble the engine, with a repair estimate of $2,900. The reason they wanted to disassemble the engine is because after an initial diagnosis for $160 they discovered the noise is not from the timing chain. Besides, it would be extremely unusual for the issue to be a timing chain at 73k. I later learned from Hyundai Customer Care that the recall still shows as “Incomplete” in their system, meaning the inspection was never properly submitted. I'm conerned that the recall was not properly performed or submitted (why does it still show "incomplete" if they insepcted it and it passed?) and that the symptoms may still indicate the exact defect covered under Recall 162 (rod bearing knock), I believe I was denied proper remedy (in a less polite way - I think they flat out lied to me about the real issue) and I was pressured toward expensive non-recall repairs without conclusive diagnosis. My understanding is that getting a diagnosis for a timing chain shouldn't cost anywhere near $800. I am requesting NHTSA review this situation to ensure Hyundai fulfills its federally mandated recall obligation.

The vehicle experienced engine stalling and rough running. We discovered it had an open engine recall related to known defects in the Theta II engine. We dropped the vehicle off at a Hyundai dealership (Hyundai Napleton) on July 1st, 2025 for recall repair, following instructions from ACV Auctions. After holding the vehicle for over three weeks, Hyundai Napleton informed us they could not perform the recall due to their internal policy against working on dealer-owned vehicles. This directly contradicts the purpose of a federally mandated safety recall, which is supposed to apply regardless of ownership. On July 23, 2025, we received a call from Hyundai Motor America, stating they would not approve the recall repair because the vehicle had been declared a total loss. This is entirely false—the vehicle has never been declared a total loss by any insurance company or official source. It appears Hyundai Motor America and the dealership are passing responsibility back and forth, providing conflicting and inaccurate information, while the vehicle sits unrepaired and inoperable. This behavior delays a federally mandated repair, puts consumers at risk, and reflects serious breakdowns in how Hyundai handles recall compliance. We need NHTSA’s help to investigate and enforce the proper handling of this safety recall.

If the airbag system is not functioning properly, the airbags may not deploy in the event of a collision, putting my life and the safety of passengers at serious risk. This is particularly concerning as this vehicle is used for daily commuting and family travel. Has the problem been reproduced or confirmed by a dealer or independent service center? I have not yet had it diagnosed by a dealer or repair shop, but I plan to schedule a diagnostic check soon. The airbag light remains consistently on during vehicle operation, indicating a persistent fault. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle has not yet been inspected by the manufacturer or any third-party representative. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, the airbag warning light illuminated on the dashboard without any prior physical impact or incident. It first appeared approximately [two days ago], and it has remained on continuously since then. Additional Information: I am aware that certain Hyundai Sonatas have been subject to airbag-related recalls, including issues with the clock spring and airbag deployment failures. Given the similarity of symptoms, I would like to know whether my vehicle may be affected by one of these recalls, or if Hyundai will provide inspection and repair support based on this known issue.

After having work done to repair the head gasket and spark plug. I was on mile ~300 after repairs and was nearing to fill up at a gas station, I started losing power and notice the check engine light was on and Gas smell filled the cabin. When I stopped the hood started smoking and there was a fire under the engine cover. My Vin is not listed on the fuel line recalls and I believe this is an oversite as it lists, faulty High Pressure hose can rupture and cause engine fires and that is exactly what happen in my case. I believe this Vin was Overlooked and I need the repairs complete. I have not completed any repairs because I believe this should have been recalled.

My engine seized and I lost power. This is the second engine this has happened to. I was given a extended warranty, but Hyundai is refusing to pay for a new engine. The mechanic advised me they are replacing engines three times a week. Mine was denied even though my engine only has 76,000 miles and my warranty is still good. This engine problem should be a new recall since the same problem is still occurring. The engine light did come on blinking. When I took it to the dealer. They knew the problem before looking at my engine since so many others need to have thiers replaced. The dealership confirmed i need a new engine. They made me send in my oil changes. They were upset I didn't have any oil receipts for my previous engine even thought it was replaced at a Hyundai dealership the first time. Consumers should not have to replace two engines. This is a safety concern with it losing power so quickly.

Dear Sir/Madam, I am writing to file a formal safety complaint regarding a dangerous incident involving my Hyundai Sonata Hybrid (VIN: [XXX] ) and Hyundai Motor America’s failure to fully correct the issue. Incident Summary: While driving on the freeway, the vehicle suddenly displayed the following alarming warnings: “Hybrid System Warning! Safely Stop and Do Not Drive” “Check Charging System” Immediately after these messages appeared, the car lost all power and shut down in the middle of the road. I had my two young children (ages XXX and XXX) in the car, making the situation extremely unsafe and traumatic. The vehicle lost all mobility and provided no opportunity to safely pull over. After contacting Hyundai Corporate multiple times, a case manager was eventually assigned to my case. At Hyundai’s request, I towed the vehicle to AutoNation Hyundai Valencia for diagnostic evaluation. The dealership diagnosed the issue as error code P0A78, indicating a transmission failure. Hyundai Corporate offered to cover 60% of the repair cost, leaving me responsible for the remaining 40%—an amount that exceeds the current value of the vehicle. This proposed resolution is not reasonable considering the severity of the safety risk and the vehicle’s low mileage. My primary concern is that this is an extremely dangerous defect, as the vehicle loses all power without warning, leaving the driver unable to move the car to a safe location. Requested Actions: A formal investigation into the safety and reliability of Hyundai’s hybrid systems, specifically in 2014 Sonata Hybrid vehicles. A determination of whether this defect qualifies under Hyundai’s warranty or federal safety defect regulations. Full compensation from Hyundai Corporate to cover 100% of the repair costs to correct this serious safety issue. Thank you for your time and attention to this critical matter. I look forward to your prompt response and appropriate action. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Formal Complaint – Hybrid System Failure, Safety Risk (VIN: [XXX] | Hyundai Case #[XXX]) Dear Sir/Madam, I am writing to file a formal safety complaint regarding a dangerous incident involving my Hyundai hybrid vehicle (VIN: [XXX] ) and Hyundai Motor America's failure to respond meaningfully to repeated requests for assistance. Incident Summary: On [XXX], while driving with my two young children (ages [XXX] and [XXX] ), my vehicle suddenly displayed the following critical warnings: “Hybrid System Warning! Safely Stop and Do Not Drive” “Check Charging System” Immediately after these messages appeared, the car lost all power and came to a complete stop in the middle of the road. This created an extremely hazardous and distressing situation for me and my family. Although the vehicle is a few years old, it has very low mileage (38,345 miles), and I did not expect such a catastrophic failure. I submitted a report to Hyundai Customer Support on May 30, 2025 (Case #[XXX]) and followed up on June 9, 2025, but have only received an automated acknowledgment—no response, investigation, or support to date. Attachments: A video clip showing the warning messages at the time of the incident (I cannot upload the video clip since the option is not there, but I do have it if required) Requested Actions: A formal investigation into the safety and reliability of Hyundai's hybrid systems. A determination as to whether this incident qualifies under Hyundai’s warranty or federal safety defect regulations. Immediate contact from Hyundai with the next steps regarding inspection, resolution, or compensation. I am cc’ing Hyundai Motor America to ensure this matter is escalated appropriately and receives the attention it warrants. Thank you for your time and consideration. I look forward to your timely response. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

the car has abruptly applied braking while driving. I took the car to get checked after that and i was told that there was nothing wrong except that the pads will need to be change sooner than later. I mechanic did tell me that it could be a safety issue because it was an uncontrollable. I than took the car to the Hyundai dealer for them to diagnose the car. They proposed that i change everything, including the brake pedal, which to me, sounded very fishy. One week ago, while driving, the car suddenly jammed on the brakes again. This particular time, it was also emitting smoke, either from the front or the bottom.

While driving my 2014 Hyundai Sonata on [XXX], the engine suddenly stalled without warning. I was in motion on a public road when the vehicle lost power, forcing me to safely pull over. There were no warning lights, check engine lights, or prior signs of engine trouble before the failure occurred. I had the vehicle towed to a certified Hyundai dealership (Norm Reeves Hyundai Superstore in Cerritos), where I was told the engine failed due to rod bearing failure caused by oil starvation. The dealership stated that the engine needed to be replaced. However, I have maintained the vehicle regularly, with consistent oil changes and maintenance, and I have documentation to prove this. Despite this, Hyundai has refused assistance and claims "exceptional maintenance neglect" without showing inspection photos or detailed evidence. This engine failure fits the exact pattern of a known engine defect already under recall for similar Hyundai models and engines, including issues with oil passages and rod bearings that lead to sudden engine failure. These vehicles have been involved in class-action lawsuits and recall campaigns for this reason. This sudden failure put my safety and that of others at risk, as the engine lost power in traffic without any prior warning. I am requesting NHTSA investigate whether this issue is part of the broader defect already under recall, and whether Hyundai is avoiding responsibility by misclassifying valid cases.

While driving on the highway, the engine of my 2014 Hyundai Sonata suddenly seized without any prior warning. There were no preceding symptoms such as warning lights, unusual noises, or performance issues that might have indicated an impending failure. At the time of the engine seizure, I also lost power steering and power brakes, which severely compromised my ability to control the vehicle and led to a dangerous situation in fast-moving traffic. I later discovered that vehicles equipped with the Theta II engine have experienced similar issues, suggesting a potential safety-related defect. I am reporting this incident as a serious safety concern and request that NHTSA investigate this matter further.
