Two weeks ago, I returned back from work and later on in the evening was driving to go to grocery store when the car seemed to get pulled to one side and started shaking when driving around 40MPH. Not knowing what was going on, I turned back and slowly drove it back home. Next morning, I thought may be there is low tire pressure ( even though it was in range), I slowly drove to get air filled. After that coming home the car started pulling on the left side and shaking around 40MPH speed. So I slowly drove it back home with flashers on and then …

This afternoon, while I was driving on freeway at a normal speed (75 miles/hour) with an ample distance (30 feet) from the car in front of me , I suddenly felt a huge impact. It was so violent that I immediately thought my car was hit by the car behind me. I stopped the car on freeway and called 911. But from the back mirror, I did not see any damage on the car behind me. I got out to inspect my car but did not see any collision damage. According to my online search, this model - Mercedes-Benz EQS - has a frequently reported issue of "P…

The vehicle throws a “charging fault” error when I try to charge my vehicle with a high speed charger. I tried two different chargers and two different locations with the same result. The safety risk is a faulty high voltage battery system. I have not taken it to the dealer yet. This just happened today. My understanding is that this is a fairly widespread issue and MB is denying all warranty claims and blaming the charging station. The only warning is the “charging fault” message on the dash display.

At the time of these incidents, my three children were in the vehicle, whi…
