I just bought a new 2021 GLE 350 1 week ago. I have noticed that when I am at a stop, the car initially idles and the green A start stop turns on. Then 15 seconds later the car jerks forward and the yellow start stop sign turns. This also happens when I am in park and the engine is running. The jerking motion is unsettling and I don’t think this is supposed to happen every time I am at a stop or in park. Also, I when I am at a stop I do not take my foot off the brake which I know restarts the car. I have brought it into service and they are telling me this is normal. I find this hard to believe that a Mercedes would lurch like this at EVERY stop and while in park. Has this happened to anyone else?
