1998 MERCEDES BENZ ML320 Engine And Engine Cooling Problems

TL* THE CONTACT OWNS A 1998 MERCEDES BENZ ML320. THE CONTACT STATED THAT THE VEHICLE WAS BEING REPAIRED BY AN INDEPENDENT MECHANIC FOR UNRELATED ISSUES WHEN SHE WAS INFORMED THAT THE IGNITION KEY NEEDED TO BE REPLACED BECAUSE IT NO LONGER FUNCTIONED PROPERLY. THE CONTACT WAS NOT INFORMED AS TO WHY THE FAILURE OCCURRED. THE KEY WAS NOT REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND THE CONTACT WAS INFORMED THAT IN ORDER TO REMEDY THE FAILURE, THE VEHICLE WOULD NEED AN ENTIRE NEW IGNITION SYSTEM. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 180,000. THE CONSUMER DISCOVERED DURING RESEARCH THAT MERCEDS BENZ INSTALLED AN INADEQUATE COMPUTER SYSTEM IN HER VEHICLE. THE SYSTEM WOULD ONLY ALLOW EIGHT KEYS TO BE MADE FOR THE LIFETIME OF THE VEHICLE. THE CONSUMER FELT IT WAS A SCAM BY MB TO FORCE THEIR CUSTOMERS TO PURCHASE A NEW COMPUTER, IGNITION, ETC, FOR THE VEHICLE AFTER THE 8TH KEY HAD BEEN MADE. THEY CLAIMED IT WAS MADE THAT WAY FOR SECURITY REASON. THE CONSUMER CALLED TWO DEALERSHIPS AND WAS GIVEN A PRICE OF $4,000 TO $5,000. THE CONSUMER FINALLY HAD THE KEY, COMPUTER AND OTHER PARTS REPLACED BY A LOCKSMITH FOR $1,400. THE RADIATOR, AIR CONDITION AND TWO MIRROR ALSO HAD TO BE REPLACED. UPDATED 07/11/12

1998, MERCEDES ML320, 70,000 MILES, BOTH CATALYTIC CONVERTERS NEED TO BE REPLACED. THERE IS A MAJOR CAMPAIGN FOR RECALL ON THIS PART FOR MERCEDES TO REPLACE AT NO COST TO THE OWNER, HOWEVER, THE YEAR OF THE CAR IS IN QUESTION. THIS INCIDENT HAPPENED 4 MONTHS AFTER THE 8 YEAR WARRANTY RAN OUT.

WHILE DRIVING IN TRAFFIC, THE VEHICLE SEEMS TO BE LEAKING EXHAUST DIRECTLY INTO THE PASSENGER COMPARTMENT CAUSING ME TO HAVE SEVERE HEADACHES AND FEEL VERY TIRED. IT HELPS SOMEWHAT WITH THE ODOR WHEN THE HVAC IS SWITCHED TO RECIRCULATE, BUT I FEEL THAT CO IS STILL SEEPING IN THE VEHICLE. *NM

CATALYTIC CONVERTER NEEDS REPLACING. ENGINE IS SOUNDING VERY LOUD. THE CHECK ENGINE LIGHT IS ON. PART WAS ORDERED IN SEPTEMBER 2005. AS OF TODAY, 12/30/05, THE PART IS STILL NOT AVAILABLE. THE MERCEDES ACCOUNT MANAGER SAID OVER 1200 CATALYTIC CONVERTERS ARE ON BACK ORDER FOR THE US AND THERE ARE 2 PEOPLE WHO HAVE BEEN WAITING LONGER THAN US IN AUSTIN FOR THE PART. HE SAID IT MAY BECOME A RECALL. WHY ARE SO MANY OF THESE PARTS ALL FAILING AT THE SAME TIME THAT SUPPLY CANNOT KEEP UP WITH DEMAND? I FEEL MY VEHICLE MAY BE UNSAFE TO DRIVE AND HAVE NO ACCESS TO A PART TO CORRECT THE DEFECT. *NM

OUR 1998 MERCEDES M320 HAS BEEN SUBJECT TO UNEXPECTED STALLING FOR SOME TIME. MORE RECENTLY THIS HAS INCREASED IN FREQUENCY AND WE HAVE PERIODS OF LOSS (REDUCTION) OF POWER WHILE DRIVING. THE DEALER ADVISES THAT WE HAVE DETERIORATION OF THE CATALYTIC CONVERTERS AND THAT THERE HAS BEEN A RECALL FOR THIS PROBLEM ON NEWER MODELS OF THE M CLASS - BUT NOT OUR YEAR. WE HAVE THE CAR AT THE DEALER WAITING FOR REPLACEMENT PARTS. WE ARE TOLD IT WILL BE A NUMBER OF WEEKS SINCE THE PARTS ARE IN GREAT DEMAND. REPAIRS WILL COST OVER $2,000 - BUT THE CAR IS CLEARLY UNSAFE. MOST FREQUENT STALLS ARE STARTING AT A LIGHT OR STOP SIGN. ONE CONCERN IS KNOWING THIS PROBLEM WITH MODEL YEARS JUST NEWER THAN OURS ARE SUBJECT TO RECALL WHILE OUR YEAR ISN'T. THE OTHER ISSUE IS HOW DIFFICULT IT WAS FOR THE DEALER TO IDENTIFY THE PROBLEM UNTIL IT BECAME VERY SEVERE (OR THEY LEARNED OF THE SOLUTION DUE TO THE RECALL OF OTHER YEARS. *JB

THE RIGHT SIDE CATALYTIC CONVERTER SPLIT AT THE NECK. WHILE THE LOCAL MERCEDES BENZ DEALER FREELY ADMITS THAT THIS IS A COMMON PROBLEM ON THIS CLASS OF CAR AND THAT THERE IS A RECALL ON THIS VERY PROBLEM, THEY TELL ME THAT MY VIN NUMBER IS NOT COVERED AND IF I WANT TO AVOID THE PROBLEMS ASSOCIATED WITH A LEAKING EXHAUST SYSTEM, I MUST REPLACE IT MYSELF. THIS IS OBVIOUSLY A MUCH WIDER PROBLEM THAN MERCEDES BENZ IS WILLING TO ADMIT TO. *JB

HARMONIC BALANCE PULLEY WAS FAILED AND WAS RECALLED 1998 MERCEDES ML320 -[XXX]. MERCEDES REFUSED TO PAY TOTAL LABOR FOR PROCESS. VEHICLE HAS NO EQUIPMENT OTHER THAN MERCEDES MADE AND INSTALLED EQUIPMENT. VEHICLE HAS MERCEDES FOG LIGHT BAR ON FRONT (STANDARD MERCEDES MADE AND INSTALLED ITEMS). IF THE PART HAD NOT BEEN DEFECTIVE, THIS CHARGE WOULD NOT HAVE OCCURRED. REGARDLESS OF THE FACT THAT IS WAS INSTALLED BY MERCEDES BEFORE I GOT THE CAR--I DO NOT FEEL THAT I SHOULD BE BURGEONED WITH MERCEDES COSTS DUE TO POOR QUALITY OF DEFECTIVE PARTS. *NM UPDATED 07/19/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

MY 1998 MLK 320 IS GOING INTO THE SHOP FOR THE TENTH TIME IN 31 MONTHS, AND THE ONLY REASON IT HASN'T BEEN IN MORE OFTEN IS I LIVE 30 MILES FROM THE DEALER. THE CAR HAS BEEN A NIGHTMARE. THE PROBLEMS ARE NUMEROUS; MANY HAVE NEVER BEEN SUCCESSFULLY REPAIRED. THE MAIN PROBLEM THAT STARTED NOT LONG AFTER I PURCHASED THE CAR (NEW) IS, WHEN I START IT THE CAR DIES. I HAVE TO REPEAT THE PROCESS AND EVENTUALLY THE CAR WILL START. THERE ARE ALSO A MYRIAD OF SMALL, CONTINUOUS PROBLEMS; WINDOWS THAT WON'T GO UP, LOCKS THAT LOCK AND UNLOCK ON THEIR OWN, PLASTIC PARTS THAT HAVE FALLEN OFF. IT HAS IS AWFUL.
