What 295 owners told NHTSA about the 2011 Mercedes-benz E-class

Brake lines rust and corrode at the plastic support clips. Brake lines are not made from quality materials. Suffrage also corroded. Suffrage was changed by dealer though when vehicle was returned the Brake lines were broken. Car entered Suffrage service with brake lines intact, rusted i wouldn't doubt but intact. When returned after changing Suffrage, brake line was broken and leaking brake fluid. Extremely dangerous to return vehicle with broken brake lines and expected Owner to drive away with no brakes. Changing brake lines was offered at a cost of $4000 but the lines were not broken upon dropping off for service. Brake lines should be warrantied and changed to a less corrosive material. Engine mounts fail and cause vibration.

I noticed about to 6 months or less that my car would shut off or stall after starting ignition and also hearing water sloshing behind the dashboard and the radio does not work and the rear camera goes on/off which is safety hazard, and the Engine symbol remain lighted up even after checking all components. Also, on a few occasion my floorboard in the passenger back seat would be soak and wet. I took the car to my mechanic, and he inform that the drain valve was not working properly. after doing some research on the internet I found that this particular incident was happening in several of Mercedes years 2009-2011 E50, that it was a recall on the water drain system. Also, on 01/17/23 my sunroof was working without any problems, I attempted to close it and it stop midday and i hear the motor working, but the sunroof did not move, I did more research and found a recall on the bonding glue for sunroof and the glass was detached without warning. Even though my vehicle is not on the recall list, my car is having the same exacts problems and issues and reported by NHTSA. I would appreciate as response or advice to solve these problems, right now my car is a safety hazard to myself and other drivers. thank you for cooperation in this matter in advance. My Case from Corporate Mercedes Customer Care#[XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

BEGINNING SOMETIME IN MAY 2013, THE CAR BEGAN LEAKING FUMES INTO THE PASSENGER CABIN WHICH MADE ME VERY ILL. AFTER TAKING IT TO BOTH PARK PLACE MERCEDES HERE IN DALLAS, AND THEN MERCEDES BENZ OF PLANO, NEITHER SERVICE DEPARTMENT COULD DETERMINE WHAT WAS WRONG WITH THE VEHICLE. AFTER REPEATED ATTEMPTS TO GET TO THE BOTTOM OF THE MATTER WITH PARK PLACE, I TOOK IT TO MERCEDES BENZ OF PLANO IN NOVEMBER 2013. THEY EVALUATED THE CAR, CHANGED THE BATTERY, AND GAVE THE CAR BACK TO ME IN DECEMBER OF 2013 FOR A WEEKEND, CLAIMING IT WAS FIXED. THE CAR, HOWEVER, WAS CONTINUING TO LEAK FUMES INTO THE PASSENGER CABIN, SICKENING ME AGAIN. I RETURNED THE CAR TO THEM FOR FURTHER EVALUATION. THEY CLAIMED TO HAVE REPAIRED IT, BUT INSTEAD OF GETTING IN THE CAR, I SENT AN INDUSTRIAL HYGIENIST TO TEST THE INSIDE AIR OF THE CAR, AFTER STARTING IT UP AND LETTING IT RUN FOR ABOUT 15 MINUTES. THAT TEST FOUND UNUSUALLY LARGE CONCENTRATIONS OF ETHANOL, PROPENE, ISOPROPANOL, ACETONE, TOLUENE, HEXANE, AND CYCLOHEXANE -- CHEMICALS WHICH ALL APPEAR TO BE COMPONENTS OF GASOLINE. I AM STILL, AS OF THIS WRITING, IN OCTOBER 2014, WRANGLING WITH MERCEDES BENZ AND MERCEDES BENZ OF PLANO OVER REPAIR TO MY CAR. I WOULD BE HAPPY TO PROVIDE YOU WITH A COPY OF THE REPORT OF THE AIR TEST FROM THE INTERIOR OF MY 2011 MERCEDES BENZ E550 COUPE. *TR
