TL*THE CONTACT OWNS A 2002 MERCEDES C320. WHEN DRIVING OVER A POT HOLE OR BUMP IN THE ROAD AT SPEEDS OF 20 MPH AND HIGHER, THE CONTACT STATED THAT HE HEARD A LOUD "METAL TO METAL" NOISE COMING FROM THE FRONT OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE BUSHINGS WERE REPLACED UNDER THE FACTORY WARRANTY. FOUR YEARS LATER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT TECHNICIAN WHO REPLACED THE BUSHINGS FOR THE SECOND TIME AS WELL AS THE FRONT CONTROL ARMS. THE FRONT DRIVER'S SIDE POWER SEAT FAILED AND WHEN TAKEN TO THE DEALER, HE WAS ADVISED THAT THE DRIVER'S SIDE FRONT SEAT ELECTRONIC CONTROL UNIT WOULD NEED TO BE REPLACED. THE REPAIRS TO THE SEAT WERE MADE AT THE OWNER'S EXPENSE. THERE WERE NO RECALLS FOR THE FAILURE FOR HIS PARTICULAR YEAR, MAKE AND MODEL VEHICLE. THE RIGHT FRONT TURN SIGNAL ALSO FAILED. HE ATTEMPTED TO REPLACE THE BULB BUT TO NO AVAIL. WHEN THE VEHICLE WAS DIAGNOSED BY AN INDEPENDENT TECHNICIAN, IT WAS CONFIRMED THAT THE WIRING HARNESS WAS DEFECTIVE. THE MANUFACTURER WAS CONTACTED AND PROVIDED NO ASSISTANCE. THE FAILURE MILEAGE WAS 80,000 AND THE CURRENT MILEAGE WAS 87,000.

I PURCHASE MY 2003 MERCEDES FROM CARMAX IN 2 YEARS AGO. IT HAD 45,000 MILES WHEN I PURCHASED IT. FROM THE TIME I PURCHASE THIS CAR I HAD TO REPLACE THE SUNROOF MOTOR, REPLACE THE SHOCKS, REPLACE THE TRUCK LOCK, REPLACE THE FUEL TANK, AND I HAD SOME TRANSMISSION WORK DONE. MY BIGGEST PROBLEM IS HAVING TO REPLACE THE LOW BEAM LIGHTS EVERY 6 MONTHS. I SUSPECT THERE IS AN ELECTRICAL PROBLEM, BUT CANNOT COMPLETELY PROVE IT WITH THE MANUFACTURER. WITH 1 YEAR, I HAD TO REPLACE THE BULBS 3 TIMES. I HAD TO REPLACE THE FRONT LOW BEAM BULBS AND THE BRAKE LIGHTS. THIS IS SURPRISING SINCE THIS CAR (UNDER MY OWNERSHIP) HAS NEVER BEEN IN AN ACCIDENT. I AM SO DISAPPOINTED I PURCHASED THIS CAR! *TR
