Our 2012 Hyundai Sonata's engine failed with no warning lights our any sounds indicating possible problems. It failed while driving and immediately stalled which could have easily caused an accident. We are the original owners of the vehicle and all recalls had been completed with the engine having been looked at as part of a recall several years ago. The mileage was around 121,000 and Hyundai has taken care of replacing the engine. We are still waiting on them to reimburse us for towing related to the incident four months after our car broke down.

Driving in traffic in town and accelerator pedal quit working. Deceleration happened until I went from 40 mph to 2mph. Then able to accelerate back up to 30mph and happened again until I coasted to a stop. Traction control light came on after second incident. Car was in park and still on. Turned car off, took key outside vehicle and exited vehicle. Car locked itself and brake lights came on and stayed on. This is a danger!!! Can cause an accident, driver has no control over vehicle at random times. Traumatic and scared to drive vehicle now.

Brake lights stay illuminated when car is off. Loses speed while in motion. ESC lights come on.

This safety issue affects Hyundai Sonatas with a turbo. The vehicle loses acceleration. The engine will rev with the tachometer functioning properly, but the vehicle speed does not increase accordingly. This is a safety issue because drivers could cause accidents when merging into traffic, changing lanes, or clearing an intersection. This issue may be related to my engine being replaced by Hyundai as part of a recall since it happened within a week of receiving the new engine. What component or system failed or malfunctioned, and is it available for inspection upon request? -- The problem is related to the wastegate actuator and/or sensor. The ECU/ECM seems to disable the turbo in the vehicle. Stopping and restarting the vehicle (rebooting) eliminates the problem until the vehicle is parked/off for at least nine (9) hours. How was your safety or the safety of others put at risk? - See introduction above. When accelerating from a stop, the vehicle's acceleration stalls at about 20-23 MPH, even with the tachometer reaching 7,000 RPMs. While driving above 30 MPH, the vehicle is very slow to accelerate so merging onto any highways or changing lanes is a high-risk maneuver. Has the problem been reproduced or confirmed by a dealer or independent service center? -- Yes. They first tried to replace the turbo boost sensor but that did not eliminate the problem. Hyundai Sonata owners have reported this problem since 2012. "Wastegate actuator sensor". Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -- Yes, the vehicle has been inspected by a manufacturer dealer service center. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -- No. The warning lamp does not activate on a regular basis with this issue. The warning lamp does appear approximately 10% of the time but again, rebooting the vehicle removes the warning lamp.

Seat belt doesn’t latch properly. It’s been happening for a while now. I have to fidget with the metal clip into the slot several times, and sometimes I just can’t wear it at all because it doesn’t latch.

Dear To Whom It May Concern, My cars VIN: [XXX] There is a recall (NHTSA Recall Number20V746000) that I found on this website for my car that the dealership below is claiming is not correct and will not work on. Springfield Hyundai Address: 754 Baltimore Pike, Springfield, PA 19064 My car has been having engine issue even after it getting services at another Hyundai Dealership Service Center. Engine overheats and smoke came out several times. Not it is jerking while I drive - loosing power. I barely was able to get the car to the service, that is how bad the state of the engine is at the moment. Initially when I took the car to the service center they said there is no recall at all on my car, even though the Hyundai customer service agent acknowledged the recall I mentioned above. After some push back from me, the service agent at the center said there was a recall but not the one I mention above a different one. I would really appreciate some help getting the recall above sorted out. Thank you in advance. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

While driving on 285 @ 60 mph the car begins alarming with a hazard light indicating emergency braking system failure then the car looses complete braking capabilities and power to drive, all while I am in front of an 18 wheeler. I have practically no control over the stirring wheel as the car has completely lost all power all I could do is throw on my hazard lights and pray that the truck sees me then I begin to coast off to the side of the highway. In 2019 the engine seized up and did the exact same thing lost total power on the highway, the engine was replaced in 2019. In 2020 the transmission was causing problems and was replaced as well, this vehicle is a death trap and I truly fear for mines and my child’s life when driving it. I have never ever really feel safe in this car after my engine failure it left with in total paranoia with it loosing total power and leaving me without control to get out the way of on coming traffic thank goodness the trucker behind me noticed I was in distress and I was able to coast off to the side. I have googled and seen that there has been many others who have had this exact same problem with the braking system. Hyundai needs to recall these vehicles for this braking problems so no has to loose there lives behind it. Please please, please help me and the others that have these issues to get this matter resolved. Every since I have gotten this car it has had nothing but major issues in my eyes it should be deemed a lemon. Please advise

I was driving on the freeway and I put my foot on the gas to accelerate and my car would not go. It had no power. It is intermittent. I can be driving and it is fine then all of a sudden it won’t go more then 30 mph. My brake lights are always going out. Now my break lights won’t turn off.
