2022 HYUNDAI SONATA Complaints

GDI fuel injectors are faulty and causing engine misfires in multiple cylinders.

Car frequently stalls out when coming to a stop. Car has to be shut down and restarted in traffic. No warning lights and no OBDII codes. Dealership states they cannot find an issue and cannot reproduce symptoms.

Loss of drive power increases the risk of a crash. A fuel leak increases the risk of a fire. What

The vehicle is still under warranty but it has 25k miles and having transmission problems. Shifting from first to second gear I feel hard shifting , also when you prepare to stop it’s hard downshift again, downshift is more hard than up shifting.

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)

2022 Sonata ; engine stops while driving without warning. After my Sonata stops; error message appears: auto stop is off; to restart engine shift to P or N

Since a few weeks after buying the car new, the battery dies and self resets every few weeks on average. No error codes occur, but the car had clearly lost power while parked, indicating an issue with power management. For the last could months, car now has 26-27K miles and is 21-23 months old, it had mostly stopped resetting. It now is dead when I go out to it, even after only a couple hours of it being parked at night or during the day. I have to manually access the car and use the battery reset button. They observe no error codes. I have read other people have the failure while driving and fear and electrical issue could be a fire hazard. At the very least, it is a personal safety issue in making me take time to access my car, which could increase my risk of being attacked while trying to get into my car safely. It has occurred 5 or 6 times since August 21, most recently on October 8th and 9th.

As I was driving my dashboard lit up with warning lights and audible alarms indicating that I should inspect my regen brake. Safety features such as lane departure, lane assist, blind spot indicator stopped functioning and my speedometer did not work. I stopped the car and looked behind the front wheels and nothing looked “unusual”. I restarted the car and all of the alarms went off again, leaving me without a speedometer or the safety features mentioned above. I scheduled an appointment with my dealership explaining what had happened. They did a diagnostic test and determined that it was a faulty E Brake Module that needed to be replaced but is on back order with no parts available in the US to order. Furthermore they do not know when a replacement is available. They reset the sensors so that my safety features were restored. This is the second time within a 14 months of purchasing the brand new vehicle that electrical systems have needed to be replaced. The first time was a faulty wiring harness located in the trunk area that the dealership had said “must have been damaged during installation at the factory”. Again-when I driving at highway speeds suddenly the alarms and warning lights were triggered-leaving me without the same safety features, speedometer and power steering/brakes. The dealership was able to replace the wiring harness and the problem seemed to be resolved until this latest incident.

I was driving on the freeway when the vehicle's hybrid battery continued to drop below a quarter of the meter. The vehicle's HUD started flashing red and the vehicle shut off. I had to pull over and wait for approximately 30 minutes before starting the vehicle back up and continuing home. The dealership stated it was a Hybrid battery issue, still under warranty, and is replacing the hybrid battery.
