What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1998 Mercedes-Benz M Class, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

ON DECEMBER 29TH WHILE TRAVELING WITH MY FAMILY ON I-77 NORTH IN VIRGINIA THE METAL SUNROOF WIND DEFLECTOR ON MY 1998 MERCEDES ML320 COMPLETELY AND WITHOUT WARNING BROKE OFF AND FLEW INTO THE PATH OF SEVERAL AUTOMOBILES. A MAJOR TRAFFIC ACCIDENT WAS NARROWLY AVOIDED. MY ML320 IS WELL MAINTAINED AND ONLY SERVICED BY THE DEALER WHOM SOLD ME THE CAR.
REAR DOOR LOCK FAILED. YH

NO POWER STEERING WHILE DRIVING WHICH IS HARD TO STEER THAT MIGHT CAUSE INTO AN ACCIDENT. THE HARMONIC BALANCER FAILED. *AK
THE CRANKSHAFT HARMONIC BALANCER PULLEY OF MY MERCEDES ML 320 GAVE OUT ON ME WHILE I WAS DRIVING. THE BELT STARTED TO BURN. I CALLED THE MERCEDES BENZ DEALER IN HONOLULU, HI AND THE SERVICE MANAGER, DAN TOLD ME THAT THERE WAS NO RECALL ON THE PULLEY TO DATE AND THAT I SHOULD BRING MY ML 320 IN TO GET REPAIRED. DAN STATED THAT THE PULLEY MAY NOT BE THE ONLY PART THAT IS DAMAGED AND THAT THE COST COULD PROBABLY GO UP IN PRICE. I STATED THAT I HAD A MECHANIC LOOKED AT IT AND SAID THAT NOTHING ELSE WAS DAMAGED. DAN INSISTED THAT THERE WERE PROBABLY INTERNAL DAMAGES. AT THAT POINT, I DECIDED TO JUST PURCHASE THE PART AND HAVE MY MECHANIC FIX MY CAR BECAUSE MY MECHANIC LOOKED AT MY CAR THOROUGHY AND I FELT THAT THE MANAGER JUST WANTED TO HAVE ME BRING IN MY CAR IN FOR THE REPAIR(S) WHICH WOULD HAVE PROBABLY COST ME A LOT OF MONEY. *AK

WHILE PULLING INTO A PARKING SPOT IN A SHOPPING CENTER AND GOING ABOUT 5 MILES PER HOUR, SUDDENLY THE ACCELERATOR WENT TO THE FLOOR AND I CRASHED INTO 2 CARS. LUCKILY, I WAS NOT HURT AND THE DAMAGE TO THE 3 CARS WAS SLIGHT BUMPER DAMAGE. I CALLED THE POLICE AND MADE A REPORT. I BROUGHT IT TO THE GARAGE THE NEXT DAY TO HAVE THE CHECKED AND NO PROBLEMS WERE FOUND. THE NEXT DAY I WENT ON THE INTERNET THE CHECK FOR SIMILAR OCCURRENCES AND FOUND SEVERAL. MY CAR WAS A MERCEDES BENZ ML320 SUV. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
