Electrical system, Jul 8, 2006
THE LIGHT BULBS IN MY 2002 MERCEDES C320 ARE REPEATEDLY GOING OUT. IN THE LAST YEAR I HAVE REPLACED (OR HAD THE DEALER REPLACE) THE TRUNK LIGHT TWICE, THE LICENSE PLATE LIGHT TWICE, BOTH BRAKE LIGHTS IN THE BACK AT LEAST ONCE. IN THE LAST 3 MONTHS, WE'VE REPLACED THE FRONT LEFT TURN SIGNAL LIGHT 3 TIMES. THE DEALER CLEANED THE CONNECTORS LAST WEEK - SAYS THAT MERCEDES KNOWS OF A FAULTY ELECTRICAL CONNECTOR PROBLEM AND AN EXEC AT MERCEDES WAS FIRED OVER THE BAD CONTRACTOR THEY USED. CURRENTLY THE FRONT LEFT TURN SIGNAL WORKS SPORADICALLY. WE'LL BRING IT IN TO GET REPLACED AND IT WILL WORK, SO I DRIVE IT HOME AND IT STOPS WORKING AGAIN. NOW THE DEALER SAYS I MAY NEED TO REPLACE THE WARNING SOFTWARE (BIG $). HE SUGGESTED I WRITE TO YOU. *JB

THE TRANSMISSION HAS REPEATEDLY LOCKED IN 2ND GEAR. THE ELECTRICAL SYSTEM SHOWS CONSTANT LIGHT, COOLANT AND AIR BAG FAILURES. THE MEMORY FOR SEATS, MIRRORS AND THE STEERING WHEEL DEFAULTS ABOUT 30% OF THE TIME. I BOUGHT THIS CAR THROUGH M-B DIPLOMATIC SALES PROGRAM WHILE SERVING IN CANADA AND BROUGHT IT TO THE USA ON RETIREMENT. M-B CANADA WON'T HELP BECAUSE THE CAR IS IN THE US. M-B USA WON'T HELP BECAUSE I BOUGHT THE CAR IN CANADA. M-B CORPORATE IN GERMANY SIMPLY REFERRED MY CASE BACK TO M-B USA. I AM NOW OUT OF WARRANTY. I WANT M-B TO EXTEND THE WARRANTY ANOTHER 4 YEARS OR 50K MILES. THE CAR IS A DISASTER. *JB

Electrical system, Sep 11, 2003, fire
WHILE DRIVING AT UNDETERMINED SPEED BRAKE LINE LOW LIGHT ILLUMINATED ON THE DIGITAL DASHBOARD. CONSUMER PULLED OVER, AND EXITED THE VEHICLE. FRONT END OF THE VEHICLE CAUGHT ON FIRE 5 MINUTES LATER. AFTER INSPECTION OF THE VEHICLE BY THE MANUFACTURER/DEALERSHIP, THEY WERE UNABLE TO LOCATE WHERE THE FIRE ORIGINATED FROM.*AK
Electrical system, Equipment, Apr 22, 2003
THE VEHICLE WAS EQUIPPED WITH A SAFETY FEATURE WHICH AUTOMATICALLY REDUCES THE SPEED OF THE VEHICLE TO 20-30 MPH WHEN VARIOUS SENSORS DETECT SOME SORT OF MECHANICAL DIFFICULTY. WHILE THE CONSUMER WAS DRIVING ABOUT 60 MPH THE SAFETY FEATURE ACTIVATED AND THE VEHICLE SPEED WAS REDUCED. THE DRIVER WAS FORCED TO PULL OVER AND THE VEHICLE WAS TOWED TOT HE DEALER. I WAS LATER DETERMINED THAT A FAULTY ESP CONTROL MODULE SENT A FALSE WARNING TO THE SYSTEM THAT MADE THE VEHICLE REDUCE SPEED. THE CONSUMER FEELS THIS FEATURE WAS DESIGNED POORLY AND THAT IT SHOULD BE DESIGNED SO IT COULD BE MANUALLY OVERRIDDEN (MERCEDES BENZ S430 2002). *MR *SCC *NLM
Electrical system, Jan 28, 2003

ON BOTH OCCASIONS, THE MESSAGES WERE GONE THE NEXT DAY. ON 1-27-03 I CALLED RALLYE MOTORS TO TELL THEM & I HAVE AN APPT FOR MARCH 10, 2003.

THE C230 COUPE SHUT OFF WHILE ON HIGHWAY
Electrical system, Aug 30, 2002
I HAVE TAKEN MY VEHICLE IN FOR REPEATED REPAIR: 1-7-02 TO 1-14-02, 2-14-01 TO 2-19-02, 3-4-02 TO 3-7-02, 5-2-02 TO 5-3-02, 5-21-02 TO 5-28-02, AND THE DEALER HAS NOT FIXED THE PROBLEM WITH THE CAR SHUTTING OFF ON ME. THERE IS AN ELECTRICAL PROBLEM, BECAUSE THE CAR WUILL SHUT OFF ON THE HIGHWAY, IN TRAFFIC, GOING UP A HILL, THEN THE DASHBOARD WILL LIGHT UP, MENTIONING SYSTEM FAILURE. I HAVE USED THE SOS BUTTON IN MY CARE REPEATEDLY TO GET HELP, BUT THAT IS STILL NOT GOOD ENOUGH. I HAVE ALSO CONTACTED MERCEDES BENZ USA, AND MERCEDES IN STUTTGART GERMANY. I HAVE PUT THEM ON NOTICE TO PURCHASE THE CAR BACK FROM ME, AND THEY HAVE A WEEK AND A HALF LEFT TO RESPOND. I TRY TO NOT TO DRIVR THE CAR A LOT, WHICH DEFEATS THE PURPOSE OF PURCHASING A NEW VEHICLE, BUT FRANKLY, I AM SCARED THAT SOMETHING MIGHT HAPPEN, BECAUSE IT HAS SHUT OFF ON ME ON I75 GOING 60 PLUS MILES AN HOUR. IT IS CERTAINLY A SAFETY HAZARD.*AK
