What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2006 Mercedes-Benz ML320, 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.

2006 ML350 WITH ONLY 112,000 MILES ON IT THE VEHICLE, WENT INTO LIMP MODE WHILE ENTERING A MAJOR INTERSTATE HIGHWAY NEARLY CAUSING A TERRIFYING ACCIDENT. MB USA RESTRICTS THE REPAIR OF THIS "MFG DEFECT" AND IT MUST BE REPAIRED AT AN MB DEALERSHIP ONLY, TYPICALLY AT A COST OVER $2,000. THE PROBLEM WILL NOT GO AWAY UNLESS REPAIRED. I MADE MB USA AWARE OF THE ISSUE AND THEY DENIED THAT ANY ISSUE EXISTS. I AM AWARE THOUGH, OF A CLASS-ACTION LAWSUIT OVER THE DEFECT IN THE 722-9-7GTRONIC-AUTOMATIC TRANSMISSION. THE LIMP MODE PREVENTS THE TRANSMISSION FROM UPSHIFTING OR DOWNSHIFTING. WHILE AT A STOP SIGN, IF THE TRANSMISSION GOES INTO LIMP MODE, THE ENGINE WILL RACE BUT THE CAR WILL NOT MOVE. I HAVE TO TURN THE CAR OFF, TAKE THE KEY OUT OF IGNITION, PUT BACK IN, AND START CAR. THIS HAS HAPPENED TO ME MANY TIMES IN THE MIDDLE OF AN INTERSECTION WITH OTHER CARS BLOWING THEIR HORN AT ME. THERE IS NOTHING I CAN DO OTHER THAN SHUT THE CAR OFF AND RESTART, THEN PUTTING IN GEAR. THIS IS HAPPENING TYPICALLY ABOUT 2-4 TIMES A DAY. THE PROBLEM TYPICALLY HAPPENS WHILE THE CAR IS DRIVING, BUT NOT NOTICED UNTIL I SLOW DOWN AND ULTIMATELY COME TO A STOP (WITH EXPERIENCE I NOW AM AWARE THAT THE TRANSMISSION IS NOT DOWNSHIFTING AND I KNOW THAT IT IS IN LIMP MODE, AND IF I HAVE TO STOP, I WILL NOT BE ABLE TO GET THE CAR TO MOVE FORWARD WITHOUT HAVING TO TURN THE ENGINE OFF AND RESTARTING THE CAR). AS I MENTIONED BEFORE, THIS STARTED HAPPENING ONLY OCCASIONALLY, BUT IS NOW HAPPENING 3-4 TIMES A DAY WHILE DRIVING AROUND TOWN.
Too few reports in this category for a page of its own — they appear in the full complaint list.
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.
