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).

I RECENTLY PURCHASED A MERCEDES 2011 E550. I FOUND THE SPEEDOMETER VERY DIFFICULT TO READ DURING DAYLIGHT CONDITIONS IT IS NOT LIGHTED. MY EYESIGHT IS 20/20). THIS IS A SAFETY PROBLEM BECAUSE IT TAKES YOUR EYES OFF THE ROAD TOO LONG TO READ THE VERY DIM SPEEDOMETER. IT ALSO CAUSES ONE TO GO AT SPEEDS NOT EASILY CONTROLLED BY A NORMAL "GLANCE"AT THE SPEEDOMETER. *TR

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2011 Mercedes-benz E-class Wagon verdict →
