Example complaints

Electrical system: “Backing out of the driveway and into traffic the car completely shut down in the middle of traffic. Both lanes came to a screeching halt. The car would not restart or allow me to put it in neutral to push it to the side. This happened on several other occasions where the car completely dies as you are driving and you have to try and get the car over to the side of the road. It has also happened as I am pulling out into traffic which is a very scary situation. The mercedes dealer is unable to duplicate the failure in their shop and there are no fault codes associated with the problem. …”

NHTSA complaint #10093119, filed 2004-09, 35,000 miles

Air bags: “I was injured in an automobile crash, due to my airbags not deploying. The impact was certainly great enough for them to deploy, however the manufacturer denies that they operated incorrectly. I would expect an impact at 35-40 MPH would be enough to deploy an airbag and prevent certain injuries.”

NHTSA complaint #10018305, filed 2003-05, 27,000 miles

Vehicle speed control: “Driving mercedes benz clk 320 on route 7 when vehicle suddenly surged forward. Unable to control vehicle crossed 3 lanes of traffic, side another car and ended up in the median strip.”

NHTSA complaint #10043613, filed 2003-10, 13,000 miles

Other or unknown: “P-7oo- I'm having same code from last year. I replace what need be replace. I brought receipts that came up to be $1100. It will not pass emission. I have gotten a extension that expire 05/16/18. I'm tired!!!”
