Owner Complaints (9)
After nearly 3 months of normal operation, your car's engine suddenly started running rough on the way home from church. The engine barely ran, smelled like gasoline, and produced white smoke. The dealer has had the car for 3 weeks investigating injector issues and expects it will take over another week for Hyundai to provide guidance on the repair.

Your car's engine suddenly jerked violently and shut off while driving on the highway at 75 mph, and it wouldn't restart—Hyundai replaced all four fuel injectors under warranty to fix it. Now at 56,400 miles, your car is jerking again at low speeds and getting poor gas mileage, suggesting the fuel injectors may be failing again. The repair will likely involve replacing the fuel injectors once more, as they appear to be the root cause of the issue.

Transmission issues: Knocking when it shifts. Also, it tries to "leap" forward sometimes when I come to a stop.
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)
