Mercedes-Benz E550 4MATIC Problems

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).

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.

Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.

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.
