The vehicle, which is under warranty, has shut itself off three times with an error message regarding the hybrid system. After having the vehicle towed to the dealership, they found no codes, errors, or messages to address. As a result, they won’t proceed further with troubleshooting and told me to address Hyundai directly. This is a significant safety hazard.
2022 Hyundai Elantra Hybrid electrical complaints
Page 2 of 2: complaints 11 to 13 of 13, newest first, as owners wrote them.
Horn has failed twice. The first time it was taken to the dealership and “fixed” - now it has failed again. The second issue is that the car accelerates on its own, both at a high and low rate of speed. While traveling at approximately 60 mph on multiple occasions, when the engine transitions from the electric motor to the gas engine, it will suddenly rapidly accelerate without any additional pressure on the gas pedal. While braking at a low rate of speed, the car seems to fight the brakes and will accelerate instead, propelling the car forward. This has almost caused multiple accidents. At the first occasion (Mar 2023), the dealer did a “transmission relearn” which mostly fixed the issue, but it has aggressively returned only 3 months later (one week ago) and is extremely dangerous. While trying to move to the side of the road and stop the car, the car continues the stop-go jerking/propelling forward and is nearly uncontrollable. The vehicle is currently at the dealership again and has not been diagnosed. On the first occasion they claimed they could not reproduce the issue. There is an open case with Hyundai regarding this. There were no warning lights or signals on the vehicle.
In responding to a districted driver that almost backed into my car, I hit the horn. The horn sounded for a second and then stopped working. In researching online and speaking with a local dealer, there are numerous reports of the horns failing. The dealer even said that the items to repair them are back ordered.
