One problem related to wiper has been reported for the 2005 Mercedes Benz C320. The most recently reported issues are listed below.
I was driving on a highway and suddenly I heard this loud explosion. My ears were ringing and I felt as if it was raining but only glass. Luckily it did not get into my eyes and I stopped the vehicle safely at the side of the road only to find out that everything is intact and I did not hit any other object; however, my sunroof had exploded. I called the manufacturer, Mercedes Benz, and they refused to do anything about it. They said that it is out of warranty. My concern is related to safety and I really think that Mercedes Benz should do something about it.
