Mercedes-Benz E550 Problems
RepairPal has identified the most common problems with the Mercedes-Benz E550 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.
The cup holder in the center console may break.
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.
Many software updates are available for the different computer systems, but if the vehicle is out of warranty, it may cost money to receive the updates (unless it is a recall). Some updates may be dealer-only, but a well-equipped independent shop can usually provide updates as well.
