MY 1995 C280 MERCEDES QUIT RUNNING IN THE MIDDLE OF TOWN AND THE CHECK ENGINE LIGHT CAME ON. I WAS TOLD MY THE REPAIR SHOP THAT THE WIRING HARNESS NEEDED TO BE REPLACED AND THIS WAS A VERY COMMON PROBLEM ON THIS YEAR CAR. THIS CAR WAS ALWAYS SERVICED AT A MERCEDES DEALER SHIP. WHY COULD THIS HAVE NOT BEEN POINTED OUT BEFORE I GOT STRANDED? I AM ALSO TOLD THIS IS A VERY EXTREME FIRE HAZARD. *NM

MY CAR ACTS HAZARDOUS. FROM TIME TO TIME INTERMITTENT ELECTRICAL PROBLEMS OCCUR LIKE ENGINE STALLS,ENGINE ERRATICALLY INCREASE RPM, CHECK ENGINE LIGHT FOR NO REASON, GAUGES NOT WORKING FROM TIME TO TIME, WHILE DRIVING THE ENGINES SEEMS TO STALL BUT RUNS ON 3 CYLINDERS I HAVE TO PULL OVER AND SHUT IT OFF TO RESTART.

(1) WHILE DRIVING MY 95 MERCEDES C280 ON I-44 HIGHWAY CONSTRUCTION I HIT A SMALL BUMP. IMMEDIATELY THE "CHECK ENGINE" LIGHT CAME ON, BUT THE ENGINE SEEMED TO OPERATE NORMALLY. I WAS ON MY WAY TO THE DEALER FOR ANOTHER PROBLEM, SO THEY CHECKED THE WARNING LIGHT AND FOUND THE WIRING HARNESS TO BE DETERIORATED, WHICH THE SERVICE REPRESENTATIVE SAID WAS A COMMON PROBLEM WITH THE ORIGINAL HARNESS. AT $1745 TO REPLACE AND WITH IT OPERATING NORMALLY AND WITH THEIR ASSURANCE IT SHOULD NOT CAUSE A FIRE OR ANY OTHER PARTS TO FAIL, I HAVE NOT HAD IT REPAIRED. WHEN I TALKED WITH CAROL, A CUSTOMER SERVICE REPRESENTATIVE AT THE NATIONAL MERCEDES OFFICE, SHE REFERRED ME TO KENNETH HOLLAND AT ELITE, THE DEALERSHIP IN SPRINGFIELD, MO FOR A REDUCED COST BUT HE REFUSED BECAUSE MERCEDES DID NOT AUTHORIZE IT. I AM CONCERNED AFTER READING OF OTHERS WHO HAVE HAD ACCIDENT...

MY SON'S CAR QUIT RUNNING. THE MECHANIC AT THE GARAGE DISCOVERED THAT THE UNDERHOOD WIRING HARNESS HAD COMPLETELY DETERIORATED. HE SPOKE WITH A MERCEDES MECHANIC WHO TOLD HIM THIS WAS A WELL KNOWN PROBLEM WITH THIS ERA CAR WITH THIS ENGINE. I SPOKE WITH A MERCEDES CUSTOMER SERVICE REP WHO SAID THAT THEY WERE UNAWARE OF AN ISSUE. I POINTED OUT THAT I WAS SEEING COMPLAINTS ON THE NHSTA SITE. HE DENIED THEIR EXISTENCE. HERE ARE THE ODI ID NUMBERS I FOUND IN A QUICK SEARCH. THEY ALL DESCRIBE THE SAME TYPE OF PROBLEM: 769109 10059002 10005610 8014541 742685 737212 836664 733503 720365 720365 10016993 898986 714914 767707 NOW, I AM IN INFECTION CONTROL AND EPIDEMIOLOGY. IF I WERE TO SEE THESE 14 RECORDS ALL ABOUT 1994 AND 1995 MODELS, IT WOULD SUGGEST A CLUSTER AND REQUIRE SOME ACTION ON MY PART. I DON'T KNOW IF THE NHTSA WORKS THAT...
