My right rear tire wares from the inside to the middle only the rest of the tire is good. I’ve had two blowouts because I can’t see that part of my tire without getting down on the ground to look at it. The part I see looks good. My tire seems to be kicked out a bit at the bottom. This is the only tire I have problems with.

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 SMELT FUEL INSIDE MY CAR WHENEVER MY CAR WOULD BE FILLED TO A FULL TANK OF GAS AND FOR A PERIOD OF TIME UNTIL THE FUEL LEVEL DROPPED. MY CAR STARTED TO DRIVE FUNNY AND NOT ACCELERATE NORMALLY THEN STOPPED ALL TOGETHER. MERCEDES DIAGNOSED IT AS A FUEL SYSTEM ISSUE. I BOUGHT THE PARTS AT MERCEDES AND HAD IT REPAIRED AND THEN THEN RECEIVED A WEEK LATER A RECALL FOR THE FUEL SYSTEM AS A SAFETY ISSUE. . THE DEALER DID NOT FIX MY CAR AND HAS AVOIDED THE ASSISTANCE TO RESOLVE THE ISSUE AND I CAN NOT REACH ANYONE AT MERCEDES CORPORATE THAT CAN HELP.
