    The contact owns a 2017 Mercedes-Benz E400 Coupe. The contact stated that the silver metal coating on the seat release lever was rough and jagged on both driver and passenger sides of the two door vehicle. The contact's son had grabbed the front seat release lever to access the rear passenger’s side seat and cut his hand. The cut was approximately 2-3 inches long. No medical attention was needed. The vehicle was taken to the dealer, and the contact was informed that the failure was common with the vehicle and that the coating was known to peel due to heat. The contact was concerned that the failure occurred as his vehicle was stored in the garage and sustained less heat exposure due to its maintenance/care. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 42,000.

    Safety Issue. The Chrome on the lever to make the seat move forward to access the back seat has sharp razor blade ridges. It has cut my hand open multiple times as well as my wife and a friend. A lot of blood, this is a serious issue. When I brought my car to the Mercedes Service center the agent told me this is a known problem and he too has cut his hand open on customers cars. This is not from wear and tear, this lever is used in frequently, I see a lot of complaints on the blogs too. Mercedes will not fix it. The Part is only $270 but they want $650 to install it.

    I was driving down the interstate when the panoramic sunroof suddenly shattered. Luckily my shade was closed but it is leaving me with a costly repair bill. I was not driving near any other vehicles, had not gone under an overpass, nor did a rock hit my roof. How could this happen and how can this be resolved? Who do I contact?

    THIS IS A COMPLAINT ABOUT THE LACK OF RESPONSE BY MERCEDES BENZ IN REPLACING THE DEFECTIVE TAKATA PASSENGER AIRBAG. MY UNDERSTANDING IS THAT MERCEDES BENZ HAS ADDRESSED ONLY 35% OF RECALLED MODELS AS OPPOSED TO HONDA WHO HAS ALREADY RESPONDED TO 85% OF THE RECALLED MODELS, REPLACING THE DEFECTIVE AIRBAGS IN QUESTION. I CALLED THE DAYTONA MERCEDES BENZ DEALER WHEN I RECEIVED THE RECALL NOTICE IN JANUARY 2019 REQUESTING THAT THE DEFECTIVE PASSENGER AIRBAG BE REPLACED. THEY REPLIED THAT THE PART WAS NOT AVAILABLE AND WOULD NOTIFY ME WHEN IT WOULD BE AVAILABLE. AS OF TWO DAYS AGO, OCTOBER 14, 2020 I HAD NOT HEARD FROM THE DEALER OR FROM MERCEDES BENZ. SINCE THEN I HAVE FOUND DOCUMENTATION AS TO THE DANGER OF THIS AIRBAG AND HOW IT HAS KILLED OR INJURED HUNDREDS OF PEOPLE. ARE WE EXPECTED TO DRIVE THIS CAR UNDER THESE CONDITIONS? DOES MERCEDES BENZ GIVE A HOOT ABOUT ITS CUSTOMERS? I AM NOT DRIVING MY CAR BECAUSE IT DOESN'T TAKE MUCH FOR THESE AIRBAGS TO DEPLOY. THE CAR HAS BEEN SITTING IN MY GARAGE EVEN THOUGH I AM PAYING TAXES AND INSURANCE ON IT. I AM 79 YEARS OLD LIVING ON A SMALL PENSION AND DO NOT THINK I WILL BE ABLE TO SELL THIS CAR WITH THIS RECALL PENDING. YESTERDAY I CALLED MERCEDES BENZ CUSTOMER SERVICE AND THEY REPLIED THAT THE PART WILL BE AVAILABLE IN NOVEMBER 2020. I AM FILING THIS CLAIM WITH NHTSA TO NOTIFY YOU THAT I AM ONE OF THE AFFECTED CUSTOMERS AND WILL BE NOTIFYING YOU AGAIN WHETHER OR NOT THE PART IS REPLACED IN NOVEMBER. FOLLOW THROUGH.
