Engine

5 reports
“I was stopped at a red light and when the light turned green to go, the car stalled. Steering wheel locked and I had to turn the car off and back on in the middle of traffic. This happened twice in one day to me. I brought it to the dealership and they cannot find a fix for this. The car also stalled on the service manager on the expressway.”
