Mercedes-Benz E550 4MATIC Problems

Airmatic Pump Motors May Fail Due to Sticking Relays

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.

Replace Brake Rotors When Pads are Worn and Squeaking

Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

Leaks Develop at Differential Seals/Cover on High Mileage/Older Vehicles

High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.

Mercedes-Benz E550 4MATIC Reviews

Endured the E550W Class Brake Pad and Rotor issue. Found a blog posting that noted an improved/corrective break pad. Passed the information on to my service representative. One good note, the dealer in Virginia Beach installed the new pads at no cost to me. The brake problem never repeated since. Sadly, MB was not the source of the correction, even after several attempts to resolve the iss...
Since purchasing new in July 2011, I have had replaced under warranty the air shocks, front struts and, as soon as the parts arrive from Germany, the interior wood trim. In addition, I have had to replace the brakes/rotors at ~29,000 miles. Shame, really, because other than the suspension and brake issues, I really like the car. The engine is terrific - exactly what a normally aspirated V8 s...
Great daily driver.
