2012 MERCEDES-BENZ ML350

The contact owns a 2012 Mercedes-Benz ML350. The contact stated that after starting the vehicle, the check engine warning light illuminated. The contact stated that the vehicle was towed to a dealer who diagnosed a failure with the camshaft. The contact researched online and found a Technical Service Bulletin regarding the camshaft failure. The dealer advised the contact that the warranty had expired for the camshaft repair. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 96,000.

The following has been happening over the last 2 - 3 yrs. Also confirmed with other customers on MB world blog site. After traveling in the car for 5-15 minutes, and sooner if connected to cell phone via bluetooth, the indicators stop working. This leads to deactivation of the blind spot assist as well. The problem is temporarily resolved after switching the vehicle off and then on again, only to recur after driving it again for 10-15minutes, and earlier if attached to iPhone via Bluetooth. The blind spot assist is then permanently inactivated. 2 Mercedes dealerships in 2 separate states where I took the vehicle could not even identify a problem, let alone resolve it. When I called MBUSA, they claimed ignorance to the issue and told me to repair or change the vehicle myself. Since this is an issue with multiple vehicles, a recall needs to be issued for this model. It’s unknown how many collisions can be attributed to this since the problem has not been acknowledged by Mercedes’. The problem has occurred almost everyday over the last 3 years. I have narrowly missed being involved in collisions because of the inactivation of blind spot assist and changing lanes. I have almost been rear ended a bunch of times because of the indicators getting inactivated. All this has happened with my family traveling me with. Please lets not wait for loss of life before a recall is initiated. thank you.

THE TURN SIGNALS STOP WORKING AFTER DRIVING THE CAR FOR A FEW MINUTES. TO GET THEM TO WORK AGAIN REQUIRES STOPPING THE CAR, SHUTTING OFF THE ENGINE AND RESTARTING IT WHICH IN TURN RESETS THE COMPUTER. THIS EFFORT DOES NOT PERMANENTLY FIX THE ISSUE AND THEY USUALLY QUIT WORKING AGAIN WITHIN TWO TO TEN MILES. THIS IS THE FIFTH COMPLAINT TO THE NHTSA WITH THIS ISSUE AND THIS PARTICULAR MODEL. THIS IS A SAFETY HAZARD WHICH NEEDS TO BE ADDRESSED BY THE MANUFACTURER AND FIXED FREE OF CHARGE. THIS HAS BEEN AN ONGOING ISSUE FOR THE PAST TWO TO THREE YEARS WITH THIS CAR. TODAY WE WERE ALMOST REAR ENDED WHEN MAKING A LEFT HAND TURN OFF OF A TWO LANE ROAD WITHOUT A DESIGNATED TURN LANE.

THE CONROL TO ACTIVATE THE WINDSHIELD WASHER IS A STALK MOUNTED BUTTON ON THE LEFT SIDE OF THE STEERING WHEEL. PRESSING THIS BUTTON WILL CORRECTLY CAUSE THE WINDSHIELD WASHER TO COME ON BRIEFLY, SPRAY THE WINDSHIELD WITH WATER AND FOLLOW UP WITH A FEW STROKES OF THE WIPER TO CLEAR THE WINDSHIELD. THE PROBLEM WITH THIS ARRANGEMENT IS THAT THE SIMILARITY OF THE BUTTON ON THE END OF THE STALK ON THE RIGHT SIDE, WHICH PLACES THE TRANSMISSION IN PARK. THUS IF YOU ARE TRAVELING ON THE INTERSTATE, FOR EXAMPLE, YOU COULD EASILY CONFUSE GOING INTO PARK WITH WASHING THE WINDSHIELD. MY EXPERIENCE IF YOU MAKE THIS MISTAKE IS THAT THE CAR WILL NOT GO INTO PARK WHILE THE CAR IS IN MOTION, BUT WILL GO INTO INTO NEUTRAL UNTIL THE CAR FULLY STOPS. THIS COULD BE A DANGEROUS MANEUVER, ESPECIALLY IN THE RAIN ON A BUSY INTERSTATE. THIS BUTTON AND ITS PLACEMENT SHOULD BE IMPROVED TO CORRECT THIS CONFUSION.

THE TURN SIGNALS RANDOMLY STOP WORKING. VEHICLE MUST BE TURNED OFF AND RESTARTED TO GET SIGNALS TO WORK AGAIN WHICH ONLY LASTS FOR AN UNKNOWN NUMBER OF TIMES. MAJOR SAFETY ISSUE. WAS ALMOST REAR ENDED WITH GRANDCHILD IN CAR WHEN TURN SIGNAL THAT WORKED MOMENTS EARLIER FAILED AND CAR BEHIND ME CONSEQUENTLY ALMOST HIT ME. MERCEDES USA WAS CONTACTED AND WAS UNWILLING TO REMEDY THE PROBLEM. THEY DIAGNOSED THE ISSUE AS A DEFECTIVE STEERING COLUMN MODULE THAT NEEDE TO BE REPLACED. THE ESTIMATE WAS ALMOST $1300. THE CAR HAS ONLY 39,000 MILES ON IT AND BASED ON RESEARCH OTHERS HAVE HAD THIS ISSUE. MERCEDES BASICALLY INDICATED THAT I WAS NOT A LOYAL ENOUGH CUSTOMER TO WARRANT COMPENSATION. I AM FORCED TO VIOLATE TRAFFIC LAWS AT TIMES BECAUSE I TRY TO NOT USE SIGNALS WHEN ABSOLUTELY NEEDED AS I DON'T KNOW WHEN THEY WON'T WORK. IN ADDITION I CANNOT LET ANYONE ELSE USE THE VEHICLE FOR OBVIOUS REASONS, SAFETY, LIABILITY, ETC. MERCEDES SHOULD HAVE DONE A RECALL AND I THINK THEY SHOULD BE LIABLE IF ANYTHING HAPPENS TO ANYONE DUE TO THIS PROBLEM.
