I started financing my 2012 Hyundai in 2019. Feb of 2021 the vehicle stopped without any warning. I paid to get the vehicle towed to Brandon Hyundai in which the did replace the engine and the starter free of charge. I was able to continue to drive my vehicle everything seemingly fine. Fast forward to late 2023 the engine light is back on, I’ve taken my vehicle to Hyundai dealership several times relating to the engine light being on each time having nothing resolved in regards to this matter with Hyundai stating theres no one there who’re able to inspect the engine. My oil light has remained on for a number of months in 2023 I’ve had to get an oil change several times this year and Hyundai isn’t able to explain as to why the vehicle isn’t retaining oil.12/15/23 around 11 pm the vehicle began to make an unfamiliar noise, stall, jerk and not accelerate. I am now unable to drive my vehicle and have to loss hope in my vehicles reliability and most importantly my safety.

The vehicle have shift control problem, it jerks hard when put into drive or reverse, also when going up a small hill it feels like the vehicle hangs in between changing from electric to gas. Also there is always a warning that comes on saying " Hybrid System Warning Safety Stop and Do not Drive". The car stops when driving, which makes it dangerous. Took it to two dealership in MCkinney and Irving and they could not fix the problem but rather charge me for diagnosis. All they say is buy new transmission. I called Hyundai for help and all they tell me is that there is no recall on 2012 hybrid model. Its frustrating because thats the only vehicle that i used for work. Need help. Thanks

Daughter was driving her car on interstate, doing 75, in the middle of traffic when the car would jerk and then loose power. The gas petal stopped working and the check engine light would come on. She had to make her way over to the shoulder, without causing an accident. Once car gets shut off and you wait a few minutes, you can start it and drive it home. This has happened about 4 times now. We are lucky that this hasn't caused an accident! This last time (yesterday), the check engine light stayed on and we were able to hook up the dianostic reader and it read the code for the crankshaft positioning sensor A circut. It says online that this is a common problem with that car and is very dangerous. How is this not up for a recall? My daughter is scared to drive her car.

I was on the expressway and car hesitated and jerked while speed began to increase followed by hybrid warning system alert. (Pull over and stop the vehicle) with a flashing ready light. Could have caused a major accident with loss of life as there was no place to safely pull over. Warning lights came in immediately after the cat jerked.

The cars engine burn oil very quickly and runs improperly. The car jerks when attempting to accelerate normally and deaccelerates when driving at normal speeds which can cause an accident with ongoing traffic.

Dear To Whom It May Concern, My cars VIN: [XXX] There is a recall (the federal safety agency 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).

I was driving on the Highway and my vehicle started blinking with all of the check lights going off and it stated “hybrid system warning stop and pull over immediately”. The car seemed to continue to jerk with the gas than the brakes went off. My steering wheel would not allow my to turn and I was very close to getting into an accident. My 6 month old baby was in the car and I feared for both of our lives. Every time I turn the car on it states the same thing... please help me

Stopped at a stoplight with the engine running, gear in drive and the brake depressed, but the engine started to rev and lurch forward--with my foot still on the brake. Moved forward a couple of feet with my foot still on the foot brake but finally came to a stop on its own.
