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. No warning light or error message was seen and when taken to the dealership they could not find anything wrong. Several months later the vehicle stopped/stalled almost causing an accident on the highway. This time the dealership did find something wrong and repaired or replaced it. Not sure exactly what it was but they mentioned something electrical Several months after this error messages began to appear on the dashboard and the car would not start. A tow truck had to take it back to the dealership. The vehicle has now been at the dealership for 4 months since February 8, 2024. They tell us they are awaiting parts or some type of...
Driving 2021 Mercedes-Benz G-550 for approximately 8min. Preceding East on a 3 lane South Florida Highway no more than 40 mph. Gas tank 75% full with V-Power From Shell. (filled-3 days prior).

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 the problem). My vehicle has under 5k miles on it and is always stored indoors in a climate controlled environment.
