TAMARA RECALL. I JUST WENT TO TRADE IN MY 75K CAR FOR A NEW MERCEDES.THE SALESPERSON TOLD ME MY CAR WAS NOT WORTH BUT 16K BECAUSE THEY COULD NOT EVEN SELL MY CAR WITH THE FAULTY AIRBAGS AND THE EPA ISSUE. I WANT TO KNOW WHY MERCEDES LET ME DRIVE MY UNSAFE AND NOW VALUELESS CAR FOR 4 YEARS WITHOUT TELLING ME. THE SALESMAN ALSO TOLD ME WHEN IT GETS 100K MILES IT WILL BE WORTH NOTHING! WHAT DO SUGGEST I DO AT THIS POINT?

I HAVE BEEN NOTICING AN INCREASING SMALL LEAK IN ENGINE OIL ON MY GARAGE FLOOR. RECENTLY I SAW A VERY LARGE PUDDLE WHILE PARKED AT A LOT AND HAD THE CAR TAKEN TO NEAREST DEALER. DEALERSHIP ADVISED REPLACING OIL COOLER AND ASSOCIATED SYSTEM PARTS. I BELIEVE IF I HAD NOT NOTICED LEAK/PUDDLE, ENGINE MAY HAVE SEIZED WHILE DRIVING. ALSO, ON MANY MB FORUMS, THE OIL COOLER IS IMPLICATED AS THE CULPRIT FOR A LARGE OIL LEAK. *TR

Took to South Bay Mercedes dealer in Torrance because of engine light on. Cause: "Obsolete CDI Control Unit Software" Repair: "Updated to latest software version" Charge: $224.99 because "not covered by Emissions Warranty Extension" Do not understand how Mercedes Benz does not provide a critical software upgrade for free or under a recall? Modifications to the diesel engine and its software done less than a year ago.

Malfunction with the air suspension. The vehicle is currently lowered and will not rise which is causing the tires to sit in a bent position and a horrible ride. The tires appear that they will detach from vehicle which is a safety risk for myself and others. After repairs from someone who presented themselves as a certified Mercedes’ mechanic, the issues still exist. The problems first existed about a year and a half ago, about 6 months after purchasing. I am making payments on a vehicle I am unable to safely drive or use for travel with m…

THE LANE-KEEPING ASSIST ONLY INTERMITTENTLY WORKS. ON OCCASION IT WILL ALERT AND TAKE CORRECTIVE ACTION, BUT EVEN ON SUNNY DAYS WITH CLEARLY DEMARCATED LANES, IT OFTEN DOES NOTHING. IN RESEARCHING THIS ISSUE, THERE ARE SEVERAL OTHER OWNERS WHO HAVE EXPERIENCED THIS AND HAVE SAID THE MERCEDES SERVICE HAS UNOFFICIALLY ACKNOWLEDGED THERE IS A BATCH OF VIN NUMBERS WHICH HAVE FAULTY SENSORS. WE PURCHASED THIS CAR BECAUSE OF THE SAFETY FEATURES AND MERCEDES NEEDS TO DO SOMETHING TO RECTIFY THIS IN ORDER TO KEEP ITS CUSTOMERS SAFE.

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 manufac…

AFTER A LONG TRIP WITH THE 2010 MERCEDES GL350 BLUETEC, I NOTICED FRESH OIL ON THE GARAGE FLOOR. I TOOK THE GL350 TO A LOCAL MECHANIC FOR AN OIL CHANGE THE DAY AFTER, AND THE MECHANIC NOTED THAT THERE IS SIGNIFICANT OIL UNDER THE ENGINE. FEW DAYS AFTER, CHECK ENGINE LIGHT CAME ON, AND I TOOK THE GL350 IN FOR A CHECK, AND ANOTHER MECHANIC CONFIRMED THAT THE ENGINE OIL COOLER SEAL IS BROKEN CAUSING THE OIL LEAK. IT SEEMS THAT THIS IS A VERY COMMON FAULT WITH MERCEDES OM642 ENGINE IN MY GL350.

THE LEFT REAR PASSENGER SEAT BELT IS BROKEN. THE MECHANISM WILL NOT RETRACT. WHEN I SPOKE WITH THE MERCEDES DEALERSHIP THEY SAID THEY HAVE BEEN SEEING THIS PROBLEM, BUT THERE IS NOTHING THAT THEY CAN DO. THEY ONLY RESPOND TO RECALLS THAT NHTSA INITIATES.
