Mercedes-Benz 300E 4MATIC Problems
Interior Wood Trim Cracks Due to Age and Sun Exposure
Miscellaneous --
Verified
Due to age and sun exposure, the interior wood trim cracks and the finish gets a cloudy haze. Replacement if the trim would be the most common solution to the problem.
Electrical Issues Due to Degraded Engine Wiring Harness
Electrical & Lights --
Verified
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
Brakes --
Verified
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).
ABS Modulator Failure Due to Dirty Brake Fluid
Brakes --
Verified
It is not uncommon to encounter premature failure of the anti-lock brake system (ABS) modulator assembly due to dirty brake fluid. Our technicians recommend flushing the brake fluid every two years in order to help prevent this problem.
