The contact owns a 2014 Hyundai Sonata. The contact stated that after parking the vehicle and leaving it unoccupied, the contact's daughter, who was seated on a porch, called the contact informing her there was grey/blue smoke emitting from the vehicle. The smoke increased, and fire droppings were coming from underneath the vehicle. The contact arrived back at the vehicle and saw the fire coming from underneath the vehicle. The fire started in the engine bay. There was property damage to the driveway, and the fire was eventually extinguished by the fire department. Prior to the fire department, the contact's daughter and neighbors attempted to extinguish the fire with water. The front passenger side tire blew out as a result of the fire. The contact's insurance company informed her that her vehicle was included in NHTSA Campaign Number: 22V312000 (FUEL SYSTEM, GASOLINE), the recall repair was never completed due to the owner being unaware of it. The vehicle was left on the driveway. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 200,000.

Odometer Fraud. The contact owns a 2014 Hyundai Sonata. The contact purchased the vehicle on April 28, 2025, with 28,974 miles from a dealer. On January 20, 2026, while attempting to start the vehicle after being parked for a while, the vehicle lost power and failed to start. The contact walked to an AutoZone nearby, where a mechanic diagnosed that the battery and starter needed to be replaced. The vehicle was repaired while with the mechanic, and the contact was informed that the actual mileage on the vehicle was 170,123. The contact reported the issue to the dealer and was informed that it would be investigated; however, the contact had not received any additional information. The dealer had taken possession of the vehicle and informed the contact that payments were still expected despite the odometer discrepancy. The manufacturer was informed of the failure and the odometer discrepancy. The failure mileage was not provided.

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.

This motor had a recall. Campaign t3g- sonata yfa 2.4L Theta II. 1 month after an oil change at the mechanic the car started making noises. Took it right to the mechanic who said there was no oil and that there was a recall on this motor for this reason. Immediately took it to the Hyundai dealership located in centereach NY. The employee who helped us was not a help. Took days and days to even get the paperwork In for the recall. Did not communicate with us unless we called him. Then eventually just said it was denied. Took weeks to get the proof from them. Completely frustrating. We submitted all proof of oil changes and maintenance and it was denied saying engine neglect! We are struggling to keep up with bills and now cannot get to work because of this. We have 2 toddlers and he is a volunteer firefighter and EMT in Centereach. He works full time at Stony Brook Hospital and is in school full time with rotations in the hospital for paramedic class. This is insane to be treated this way

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. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
