What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I could move my hands, feet without numbness or tingling neck didn't hurt, chest had sharp pinpoint pain, there was smoke, engine was damaged I was worried about fire. Reached for seatbelt a guy wanted me to stay. Then firefighter said to leave to spray. Ems on scene.
The mechanic noted that the control arm was hollow and seemed to be rusting. He was able to detect that the driver side control arm had a similar problem in the making and that the stabilizer bar had stress crack. All were replaced over the next few weeks while I was on vacation.
Pulling car into driveway and it just surged or took off, running into the garage door and crashing. I had foot on brake leaving black marks on driveway. Had 2 witnesses to the incident. Exact day not listed as I do not have that with me. Since that time I have noticed in the newspapers and t.v.
I was hit in the driver side door and my air bag did not deploy. Mercedes sent out a technical team who found that the airbag operated properly. They said I got hit too low but I was hit by a ford work van whose bumper is 27" up. There is not an inch of that door that is not caved in.
My airbag did not deploy causing injury to my shoulder from the door buckling into me and moving my seat and console over. All professionals that see this car are very surprised I am not critically injured or dead. Mercedes-benz sent a technical team to inspect the vehicle and found the airbag operated properly.
Numerous blow out and shredding of firestone low profile tires. The tires lose air pressure very quickly within weeks of filling & this often leads to the tire heating up and catastrophic side wall failure. Most of the time the shredding occurs on the inside of the rim and is not visible from the outside.
While driving down the street both the right and left led instrument clusters that indicate what gear you are in and the outside temperature both failed and are unable to read. I consider this a safety issue only because I cannot tell which gear I am in and often times I must guess at what gear it is in.
The gps adapter does not fit tightly in the cigarette lighter socket. I use a paper piece to make it tight, however it gets loose and gets gps disconnected while driving. Many times when I realize this either I have gone too far or I have to make sudden decision, which makes it dangerous.
