Owner report 11421207 · 2021-06-16 (June 16, 2021)

While pulling away from a red light, the vehicle jolted a small amount, then it shut down, only providing power to the dashboard, which produced an array of safety warnings. Power steering and throttle were completely dead leaving me powerless in traffic. I pulled to the shoulder of the road, placed the vehicle in park (as it seems that the failure put the car into neutral). I was able to restart the vehicle and continue driving home with no warning lights or issues. (Several other owners are having this same issue-I found them by googling …

Shortly after purchasing a new Mercedes Benz 2021 G550 on [XXX], the SUV started having electrical problems. During early 2022 the vehicle shut off while at a red light and would not restart until a few minutes later.
