I went to start my car up 10 days ago and it began to alarm with a message to check the brake system. My car was stuck and wouldn't drive. This also happened in July 2022 while I was on the highway. I could no longer accelerate and the gas pedal no longer gave power. I had to put on my hazard lights and coast to the far right lane. I took it to the Hyundai dealership near by and they said it wasn't safe to drive. I left it there and was told that Hyundai would replace the part in good faith at no charge but charged me $700 for labor. This is becoming a problem. I was told the car could catch fire while driving or while parked and that I could continue to drive it. I decided not to drive it because I do not feel safe.

I have a 2012 Hyundai Sonata Hybrid that has a problem with its ABS Module. It is overheating and causes my car to stop its brake and motor functions while driving. I contacted the dealership to get a rental or replacement in the meantime and they told me there is nothing they can do and to drive with caution. I called the manufacturer to get a rental for the meantime and they told me the same thing. I have looked on the recall documents and it says they should give me a vehicle in the meantime if it is unsafe to drive. Please, I don't even want the car at this point because of all the problems with it and with my dissatisfaction with customer service from any Hyundai business. But if I could just get a car that is safe to drive while I wait for the recall to have a remedy , I would take that.

while traveling at interstate speeds vehicle engine failed along with some associated electronics. Vehicle was a risk of being impacted by other vehicles traveling at greater speed until moved to the shoulder. Vehicle was towed and inspected by service center that stated the engine was seized up due to possible bearing issues. No warning lamps illuminated until time of engine failure. Vehicle has not yet been inspected by Hyundai or insurance.

While driving on the freeway, the Hybrid system warning, safely stop and do not drive will alternately flash with check brake and continuously the alarm sound with the park brake red light. The car would loose acceleration, and the brake pedal goes to the floor when applied. Once stopped, I restarted the car and the same things happen. The car can accelerate on and off for about 5mph. Brake pedal still goes to the floor. After restarting the car for 30-minutes- 1 hour, there are no warning lights or alarm. The car can be driven again. I brought to independent mechanic and found the code C1604 and there’s a recall 251 on ABS brake system- recommended to bring to dealer. Brought to dealer, they say that recall 251 had no fix yet. They diagnosed that the safety plug relay needs to be replaced. Dealer replaced it and said that the car is fixed. Pick up the car from the dealer. After 20 miles of driving the same problem occurred- Hybrid system warning, safely stop and do not drive will alternately flash with check brake and continuously the alarm sound with the park brake red light. Had the car towed back to the dealer. After 2 days, the dealer says it’s possibly a transmission issue. I asked how come it wasn’t diagnosed the first time around? No clear response.issue occurred 4 times already.
