“While I was travelling on highway, I got an alert about collision system being inoperable, I took my car to the dealership, it was investigated and was told to me that I had an accident? I did not. I am thinking it was some kind of an electrical/radar sensor issue? It did not affect my speed or ability to accelerate”

“I have a 2015 mercedes benz C300. I have not even owned the car for one year and I have already had a whole list of problems that are not being resolved. The stereo quit working, the back up camera doesn't work, the AC works on and off, and my hands free does not work at all. This all happened one day when I turned on my car to leave work. The stereo was frozen and it has stuck like that. Mercedes has not sent out a recall or any notification at all. I took the car to the dealership and they sent it back with no idea of when it will be fixed.”
