There is a recall for this significant safety risk. I contacted my local Mercedes Benz about recall remedy on 6 January 2023 and they confirmed the recall and said MB would issue steps to get this taken care of in the beginning of February. It is now 18 February 2023 and this has not happened and I have received no communication from MB and yet the safety risk still exists and could be life threatening.

Going to work in the morning and pulling out of the garage my foot was on the brake not the accelerator in reverse suddenly the car surged by itself while I had my foot on the brake. The car went in reverse very fast hitting our side concrete side wall. (the distance is about (28ft) the impact was so hard that the passenger window was completely broken and the passenger side of the back frame of the mercedes was smashed. It happened so fast that I lost control of the vehicle I could not stop the car the brakes did not work. After I hit the wall I was jolted forward and I smashed the front end of the car with the garage. The car finally stopped in the middle of the driveway. Again, I did not put the car in drive when I was jolted forward the car went forward from the impact of the hit from the wall and I did not put my foot on the accelerator.
