What 76 owners told NHTSA about the 2012 Mercedes-benz Gl-class

I would like to file an official complaint with Mercedes Service center prior to escalating. Due to neglection the part of your authorized dealership, I am confronted with poor and conniving customer service, strong safety concerns, and financial loss. Also, Euro Motors did not report any issues with the vehicle wire harness during the pre inspection. During the pre inspection the only thing Mechanic pointed out was the rear left air suspension bag losing air (see attached videos of pre and post inspection).I brought in my GL350 for the manufacturing recall on September 20th, with sufficient time to file for the $878.75 cash back rebate for Class Action Settlement. Euro Motors of Germantown, deliberately or carelessly kept my vehicle past the due date of the rebate. When I received the vehicle almost a month later, it stalled in the middle of the highway, risking my life as it gave no prior indication of stalling. When I opened the hood to inspect the vehicle, I noticed the harness wires were tampered with. I have actual evidence of the engine prior and post Euro Motors maintenance, which I will make available if necessary. I have lost my trust with this dealership performing and further work, and I would like Mercedes to take further action to ensure my trust in their brand. I can be available for direct discussion with contact information below. On 20th October 2022, I received my car back from the dealer. I was told their mechanic performed all safety inspection and the car is roadworthy. After I inspected my vehicle I found Euro Motorcars Mercedes-Benz Germantown location left a leaking fuel line and return the car back to me. I would like NHTSA to investigate this safety issue.

THERE IS A STRONG ODOR OF GAS COMING FROM THE BACK DRIVERS SIDE WHEEL WHEN PARKED AND WHEN DRIVING. WE HAVEN'T FOUND ANY GAS ON THE FLOOR OF OUR GARAGE BUT DEFINITELY A STRONG GAS SMELL AND FUMES. WE HAVE TRIED TO FILL THE TANK 1/2 WAY BUT IT DOESN'T SEEM TO HELP THE SMELL/FUMES ARE THROUGHOUT OUR ENTIRE HOUSE INCLUDING THE 3RD FLOOR WHEN THE CAR IS PARKED IN THE GARAGE. I AM WORRIED ABOUT IT EXPLODING OR CATCHING ON FIRE. I HAVE READ ONLINE OF OTHER MERCEDES LEAKING GAS AND WONDER IF THIS IS HAPPENING TO ANYONE ELSE WHO OWNS A GL 450?

WHILE DRIVING AT HIGHWAY SPEED IN THE LEFT LANE OF A DIVIDED HIGHWAY, THE VEHICLE SUDDENLY AND WITHOUT NOTICE LOST ENGINE POWER AND POWER STEERING. THE WEATHER CONDITION WAS LIGHT RAIN AND THE ROAD WAS WET. I WAS ABLE TO MOVE OVER TO THE SHOULDER OF THE HIGHWAY AND RESTART THE ENGINE BUT IT DIED WITHIN TWO TO THREE SECONDS. I THEN RESTARTED THE ENGINE SEVERAL MORE TIMES AND WAS ABLE TO MAINTAIN A RUNNING ENGINE AFTER ABOUT 5 RESTART CYCLES. THE ENGINE LOSS OF POWER HAS BEEN TRACED BACK BY A MERCEDES REPAIR CENTER TO A MALFUNCTION OF THE ELECTRICAL WIRING HARNESS CONNECTED TO THE FUEL PUMP IN THE GAS TANK. THIS INCIDENT DEMONSTRATES THAT THE ELECTRICAL SYSTEM MALFUNCTION REPORTED UNDER ITEM #10745399 OCCURS IN WET ROAD CONDITIONS AND NOT JUST WHEN TRAVELING OVER A PUDDLE. MERCEDES REFUSES TO REPAIR THIS SAFETY RELATED DEFECT UNDER WARRANTY.
