2011 Mercedes-Benz E350 Engine Problems

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).

MB, WITH DIESEL EXPERIENCE OF OVER 80 YRS, SHOULD KNOW BY NOW WHAT MATERIAL THEY USE IN THEIR DIESEL ENGINE. THIS DEFECT WILL DEVELOP IN EVERY CAR THEY MADE IN THE SAME WAY AND THEY SHOULD RECALL THE CARS AND CORRECT THE ISSUE 2. THE DRIVER SEAT IS TORN ALONG THE TUFT IN THE SEAT.THIS IS HAPPENING ACROSS THE BOARD ION ALL MB CARS USING THE SAME MATERIALS. AGAIN, IT IS A MATERIAL ISSUE AND SHOULD BE CORRECTED. OLD MB SEATS LASTED FOR DECADES!
