Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We had trouble towing our travel trailer, we looked under our car and the weld was broken on our hitch. We took it to the dealership and their inspection confirmed it was a bad weld .they want us to pay $900 to fix. This is the exact same problem and hitch that was recalled in 2007 and 2008, so mercedes continued to use the same hitch and weld in year 2009 and now it has failed after 4 times towing. The rust on our picture indicates the weld had failed much prior to us realizing it.”
NHTSA complaint #10983420, filed 2017-05, 39,000 miles“I was driving on my way home from work today 2/3/2017 and I was merging onto highway when I heard a loud explosion. I then saw that my sunroof had shattered and was bowed out. There is a large hole in the center of the sunroof and the rest of the glass is spiderwebbed. Nothing had hit my car or my sunroof. I was only going about 15 MPH as I was still on a on ramp. It was very scary and dangerous. I called mercedes who is no help. They need to recall this or be held responsible. This could have caused me to crash or if my sunroof cover was opened I would have been showered in glass.”
NHTSA complaint #10949492, filed 2017-02, 104,000 miles“I was driving 70 down an interstate a Saturday around 4:30 pm and heard a noise as if my sunroof opened a bit, then I heard a loud pop and a rush of air and looked in my rearview mirror and didn't see anything, I looked up seen the sunroof was gone. All I could think about is that could have really caused a serious accident. Glad no one was around me at the time. I doubled back twice and could not find the sunroof glass. I got home and put a couple pieces of cardboard and plastic down and duct taped it before the snow storm hits. …”
