SUNROOF PANEL DETACH AND LET GLASS PANEL LOOSE ON ROADWAY. I FELL THAT MY MODEL SHOULD ALSO BE PART OF THIS CLASSIFIED AS 22V-954. HOWEVER, SINCE IT WAS NOT ON THE LIST SO THERE FORE THEY REFUSED TO RECOGNIZE IT AS BEING ONE OF THERE PROBLEM. I BELIEVE THIS IS AN OVER SIGHT WITH THEM. I REPORTED IT TO THEM AROUND JULY 31 2025 TO THE MERCEDES CARE PEOPLE. THEY TOLD ME THAT SINCE MY CAR DID NOT HAVE A WARRANTY OR AN EXTENDED WARRANTY AND THAT THE CAR WAS OVER NINE YEARS OLD PLUS WITH THE MILEAGE ON THE CAR THAT THIS WAS NOT THERE PROBLEM. MY INSURANCE AGENT TOLD ME THAT THIS WAS A MECHAICAL FAILURE AND THATA THEY WOULD NOT BE COVER UNDER MY POLICY. HOWEVER AFTER READING THIS ARTICLE THEY KNEW THAT THIS COULD HAPPEN TO ANY OF THERE MODEL. I'M ASKING FOR YOUR ASSISTANT TO RESOLVE THIS ISSUE.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
