One problem related to wiper has been reported for the 1999 Mercedes Benz C230. The most recently reported issues are listed below.
While driving on 11/21/2020 at about 930am on northbound I-75 doing about 70mph as the rest of traffic in georgia when my sunroof (not opened) suddenly detached and blew off the vehicle. I initially heard a loud noise and wasn't at first what happened. I looked up and sunroof panel with the glass was gone. Fortunately there were no vehicles around me so as far as I know no one was hit or injured. I eventually pulled over and looked at the top of the vehicle and the sunroof panel was gone. I finished by business that morning and retuned home safely to our home in ocala, FL.
