2 Air Conditioner problem of the 2008 Mercedes Benz C300

Failure Date: 07/27/2016

I was driving on a straight highway at approximately 70mph when, all of a sudden, I heard a loud explosion. A few seconds later, I felt the car pulling slightly to the right. A few glass fragments then started to come through the sunroof cover and this is when I surmised that the sunroof had shattered unexpectedly. This happened around 6pm towards the end of July in texas during a hot day (~+100deg f). I had the air condition on the coolest (60 deg f) setting and a low to moderate blower fan speed. When I got home, I noticed that the sunroof had exploded outwardly. I can easily imagine someone swerving due to the shocked of the loud explosion and causing an accident.

3 Air Conditioner problem of the 2011 Mercedes Benz C300

Failure Date: 11/02/2013

Car has a strong sulfur/rotten egg smell at acceleration. Had to complain to local mercedes-benz dealer several times over 3 years before someone looked into the issue. The dealership blamed an accident in Jan 2014 for problem, but sulfur smell during acceleration was present before the accident. Instructed to tighten the seal on the bumper in October 2016. Still having sulfur smell enter car when accelerating especially with the air conditioner on, though not as strong as before the bumper seal was retightened. The smell still persists so the problem is still there.
