Air Bags
Filed Sep 6, 2022MN

When reviewing the vehicle for purchase I noticed the SRS light on. I brought it to the dealerships attention. They instructed me to bring it back in the morning after signing paperwork so they could fix it. After I brought it back they let me know that they didn't see any SRS lights and would not be servicing the vehicle. There has been multiple mechanical issues with the vehicle including but not limited to the transmission going out, break recalls, engine leaks and now I'm being informed that my passenger air bag is deactivated. I just want a safe vehicle.

Car is extremely hard to turn/loss of power steering. Noticed that there was a recall on these vehicles but my vin was not included. Mechanic said Power steering rack is bad. This has been an ongoing issue with this car since purchased with only 70,000 miles - not sure why this VIN was not included in the recall?

OUR 2006 MERCEDES ML500 HAS HAD BOTH INTERNAL MECHANICAL LATCHES TO DOORS BREAK APART INSIDE THE FRONT DOORS AT DIFFERENT TIMES. WHAT HAPPENS IS THAT WHEN USE USE THE ELECTRONIC SWITCH TO OPEN THE VEHICLE DOORS, THEY UNLOCK OK BUT THE DOOR WILL NOT CLOSE OR LOCK AFTER INITIAL OPENING. WHEN THIS HAPPENS, YOU CANNOT CLOSE THE DOOR (THE LATCH IS BROKEN). THIS IS A LIFE THREATENING PROBLEM IF YOU HAVE TO DRIVE ANY DISTANCE TO GET TO A MERCEDES DEALER. OF COURSE THEY NEVER HAVE THE PARTS IN STOCK. ON ONE OCCASION, I HAD TO TRY TO PHYSICALLY HOLD THE PASSENGERS SIDE FRONT DOOR CLOSED UNTIL WE COULD GET SOME ROPE TO TIE FROM ONE DOOR TO ANOTHER. FORTUNATELY WE NOW HAVE A ROPE IN THE CAR AT ALL TIMES. MY WIFE WAS ALONE IN THE VEHICLE YESTERDAY AND HAD TO TIE THE DIVERS DOOR TO THE FRONT PASSENGER DOOR. FORTUNATELY SHE WORKS 1 1/2 MILE FROM THE LOCAL MERCEDES DEALER. IT WAS STILL VERY SCARY FOR HER BECAUSE WHENEVER SHE TURNED A CORNER, THE DRIVER'S DOOR WOULD SWING OPEN SLIGHTLY. AGAIN THIS IS A DANGEROUS PROBLEM AND IS A $1,000.00 REPAIR. THE LAST TIME THIS HAPPENED WAS ABOUT A YEAR AGO.

Exterior Lighting

THE REAR BRAKE LIGHTS SOCKETS ARE GETTING BURNT CAUSING THE BRAKES LIGHT TO FAIL. CORROSION ON A CONNECTOR CAN CAUSE THE TAIL, BRAKE OR REAR TURN SIGNAL LIGHTS TO DIM OR FAIL. THIS IS A SAFETY ISSUE BECAUSE IT CAN MAKE CARS LESS VISIBLE TO OTHER DRIVERS, WHICH CAN INCREASE THE RISK OF A CRASH. THIS IS THE EXACT SAME ISSUE WITH THE 2008 - 2011 MERCEDES C CLASS WHICH RECENTLY HAD A RECALL ISSUED.

Power Train
Filed Sep 3, 201378,400 milesCA

SPORADICALLY, WHILE DRIVING ALONG ON LOCAL ROADS OR THE HIGHWAY, THE CAR'S TRANSMISSION DOES NOT SWITCH HIGHER THAN THIRD GEAR. THE PROBLEM OCCURS ABOUT ONCE A MONTH. UPON ENGINE RESTART, VEHICLE DRIVES PROPERLY. MY PEDAL SHIFTERS DO NOT WORK WHEN THIS PROBLEM OCCURS; I CAN TRY TO SHIFT GEARS WITH THE PEDAL SHIFTERS, AND THE SOFTWARE INDICATES A CHANGE FROM 3RD TO 4TH GEAR, BUT THE ACTUAL TRANSMISSION DOES NOT CHANGE GEARS. IT REMAINS STUCK IN THIRD GEAR WHETHER I SPEED UP OR SLOW DOWN. IF I PLACE THE VEHICLE IN PARK AND TRY TO REVERSE, THERE IS NO POWER TO THE VEHICLE UNTIL I RESTART THE CAR. THIS SEEMS TO BE OCCURRING WITH MORE AND MORE FREQUENCY. I HAVE A SAFETY CONCERN THAT I HAVE TO PULL OFF THE ROAD AND RESTART MY CAR WHENEVER THIS OCCURS. THIS SEEMS TO BE PROBLEMATIC FOR SEVERAL OWNERS ON THE NHTSA SITE AND ONLINE. *JB

Reading this record

NHTSA has issued a do-not-drive warning for a recall on this vehicle.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
