There are 7 owner-reported electrical system complaints for the 2011 Mercedes-Benz E-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.

MERCEDES 2011 E550 HAS A SPEEDOMETER THAT IS VERY DIFFICULT TO READ AND REQUIRES EYE DIVERSION FROM THE ROAD TO AN UNSAFE EXTENT TO VIEW YOUR DRIVING SPEED. *TR
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
