On 2/17/24 the vehicle was parked in front of my house. There is a slight grade. The vehicle had been parked for approximately 1 hour when my neighbor called me to tell me that the vehicle had rolled down the hill and into his storage building. The vehicle rolled on its own. I have video evidence that no one was in or around the car at the time of this occurrence. I also, have 2 eyewitnesses who can corroborate this story. Due to safety concerns, I immediately returned the vehicle to Mercedes. I have .MOV files and pictures JPEG that will not upload for some reason.

First week, the car would take off fast as soon as the brakes were released. Then first time I used the heat there was a crackling sound coming form the side of the center display and it got extremely hot, I was on the FWY driving in the rain. Brakes: Intermittently, when braking, the car speeds up as if shifting to N, problematic in the FWY traffic behind another car, sometimes the brake pedal can be heard rattling really lose underfoot, brakes also used to groan when backing up. Electrical: intermittently, the door/trunk lock, side mirror, garage door opener do not work, and the dash displays change by themselves, the worst is the unreasonably hot center display that burns fingers, and becomes untouchable on hot days. Transmission: seems not to work in unison with the accelerator as sometimes the RPM needle hits 3-4 but the car will not speed up or is sluggish. Other: the car intermittently kicks, like being rear ended, it happens at different speeds and stopped or driving, continuing a few times intermittently for a day or two. Twice have taken the car to MBZ dealership, one for 2 days, another for 10 days, they said they reset everything and all was fine. The issues are intermittent and hard to duplicate for some one who does not drive the car regularly. The dealership has been great but I do not feel they are able to reveal the problems with the vehicle. The car is like a computer with a virus and sometime gives erratic response.
