The bonding agent on my roof ( between the glass panel and frame of car) is breaking down- The other week, when I had the sun roof open in direct sun ( my car is usually parked in covered parking) the bonding was sticky to the touch, and got all over my hand when I inspected the rail. I took it to Mercedes, because I thought that it was under recall # 202004011 for this very issue, but they said it was not a covered model. They wanted to charge $300 for an inspection and diagnosis. MBUSA customer service also not interested in investigating whether this issue is affecting my model car. In the recalled models, there is a danger of the glass roof separating from the vehicle.

MY DAUGHTER IS 18. THIS WAS MY MERCEDES THAT I HANDED DOWN TO HER THAT I THOUGHT WOULD BE SAFE. HOWEVER, THE DRIVER AND PASSENGER SIDE SEAT BELT BUCKLES ARE NOT LOCKING THE SEAT BELTS PROPERLY. THIS IS PART OF A RECALL DONE BY MERCEDES. HOWEVER, WHEN I CALLED THE MERCEDES DEALERSHIP AND ASKED THEM IF MY CAR WAS RECALLED, THEY SAID THAT MY VIN NUMBER WASN'T ONE OF THE CARS. I DON'T UNDERSTAND IF MY CAR IS DOING SAME THING THAT THE RECALL SAYS. THERE WILL BE A HECK OF A LAWSUIT IF MY DAUGHTER WAS TO GET IN A WRECK AND HER SEAT BELT MALFUNCTIONED. THIS IS WHAT THE RECALL SAYS AND MY DAUGHTER'S VEHICLE IS DOING THE SAME THING. ......SOME SEAT BELT BUCKLES MAY HAVE A BURR ON A METAL COMPONENT OF THE LOCKING MECHANISM. THIS COULD PREVENT THE SEAT BELT FROM LOCKING UNDER CERTAIN CONDITIONS. IN THE EVENT OF A CRASH, THE SEAT OCCUPANT MAY NOT BE PROPERLY RESTRAINED, INCREASING THE RISK OF INJURY. DEALERS WILL REPLACE THE AFFECTED SEAT BELTS. THIS RECALL IS EXPECTED TO BEGIN ON DECEMBER 22, 2003. THE MERCEDES-BENZ RECALL NUMBER IS 2003 120006. YOU WOULD THINK MERCEDES WOULD TAKE CAUTION AND FIX THIS IF THE OWNER IS TELLING THEM THE SEAT BELT IS DOING THE SAME THING ON THE CAR THAT THE RECALL SAYS. I WOULD LIKE FOR MERCEDES TO TAKE FULL RESPONSIBLE AND FIX MY VEHICLE AT NO CHARGE. IF NOT AND SOMETHING HAPPENS TO MY DAUGHTER, I WILL FILE A LAWSUIT. PERIOD. THANKS

I WAS ABLE TO PUT OUT THE FIRE AND PULLED THE FUSE BOX COVER OFF AND FOUND THE FUSE BOX WAS WHERE THE FIRE HAD STARTED. THERE WAS A PAPER WITH FUSE SIZES AND LOCATIONS PUT (BY MERCEDES) IN BETWEEN THE FUSES WHICH HAD BEEN SINGED, AND PART OF THE FUSE BOX AND SOME OF THE FUSES HAD MELTED. I DID AN INTERNET SEARCH AND FOUND A COMPLAINT ON A MERCEDES FORUM WHERE THIS HAD HAPPENED TO ANOTHER 2004 MERCEDES C230.
