“While driving in a parking lot at a low speed my car turned off by itself I kept pushing on the accelerator but I realized the car is not moving, it had shot off by itself. I turned the car on manually and then worked. It was a terrifying situation. I kept thinking what if I was on the freeway and my car had turned off while the moving traffic was about 70 miles. I contacted mercedez bez and I was told it might have been a glich and that they could not duplicate it. I feel that is a very dangerous glich.”

“I was driving and came to a stop sign. When I was getting ready to pull off my entire vehicle automatically went into park and shut off. I was almost rear ended by the vehicle behind me. People were blowing at me. I just restarted the vehicle after a few attempts it started and I drove off. Also my entire dash went black while I was driving. I also felt water on my feet why on the passenger side ( like a light mist).”

“My 2020 GLE 350 first displayed a problem with left indicator on front left hand head lamp. I took an appointment with my Mercedes dealer for repair. Then it started showing all kinds of safety problems on the screen -like blind spot monitoring, collision warning etc not working. I parked it in my garage, shut off the engine, locked it and in a couple minutes, it started a blower like sound. I called Mercedes service center and described the problem. They sent a tow truck. …”
