I leased my brand new Sonata at the end of August in 2022. in November 2022 I was driving on the highway and my vehicle started to decelerate. I stepped on the gas pedal and it just went slow and slower. I was able to make it home but after shutting the car off it would not start again. I had it towed to my dealer and they fixed something with fuel injection. in February 2023 the same thing happened with only 4500 miles on the car except this time my car decelerated so badly I pulled to the side of the road and it immediately died. I had the car towed again and they fixed it again. The car was good for a while but on [XXX] of 2024 the deceleration issue happened again. it did not stall out on me and I was lucky enough to be able to get the car to my dealer to have them do a diagnostic check. They did not find anything. This is baffling to me. I guess I need to break down again for, something to be fixed with this car. my complaint is that while driving my car and if I break down it is unsafe for me and other cars on the road if my vehicle just dies. I do have a job and also like to travel out of town sometimes. I do not feel safe with this car. It broke down twice in the first year so it did not qualify for the lemon law in my state of Pennsylvania. Please provide some information on what I need to do to keep myself and other drivers safe. Thank you very much. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loss of power while accelerating. Engine overheat notification. High oil temperature.

- Carmel, NY, USA

While I was driving the vehicle late last year (2022) I pulled out of the parking lot of my office and my vehicle did not accelerate even though I was pressing the gas pedal. I pulled over, turned off the car, restarted the car, and everything was normal again. This morning (8/15/23) as my wife was driving my son to school, the car did the same thing and the vehicle did not accelerate even though the gas pedal was pressed and the RPM's were registering but there was no drive power. She had to pull over and restart the car as well.

My 2022 hyundai sonata sel completely shuts down while driving, most recently it happened twice in the middle of an intersection when I was trying to make a left turn it is very very scary and dangerous. I purchased the vehicle in July 2022 and since then it has had consistent idling issues meaning if it's parked too long it will just turn off but now it is turning into while I'm actually driving at the engine dies and again recently it's been in the middle of intersections which is very scary. My check engine light came on it only 4000 miles on new car - very concerning. I encourage anyone having intermittent engine stalling in any way to make sure we are reporting this.

Our 2022 Hyundai Sonata completely shuts down while driving. We purchased the vehicle in May 2022 and since then it has died over 10 times and has almost caused multiple accidents. We have 3 video footage that we have shown Hyundai corporate and the dealership service technicians. They drive the vehicle a few miles and give it back unable to duplicate it. Hyundai refuses to buyback the vehicle due to safety concerns. We do not know what more we can do and have been working on this since August. We no longer drive this vehicle as it is too dangerous and will eventually cause an accident.

On multiple occasions, the car has intermittent acceleration issues and hesitates when the automatic transmission is shifting to the next gear. Without warning, the car completely turned off - engine failed - while driving and in the middle of making a turn, and luckily oncoming traffic stopped in time before we were in an accident. The local dealer has been unable to replicate the problem; however, there is an open recall on the same make and model but my VIN is not currently included in this recall. This is not a coincidence and this vehicle is not safe to drive. I also already contacted Hyundai directly but the case manager has yet to resolve the issue, just says the VIN is not part of the recall.
