Bad spark plug wires can cause misfires; the Check Engine Light may illuminate.

The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.

As a way to increase braking performance, the brake pads and rotors are make of a softer material and may be in need of replacement after approximately 20,000 miles; owners should be vigilant about getting their brakes checked.

The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

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.

An engine oil leak may develop from the oil level sensor. Replacement of the leaking sensor will commonly correct this concern.

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Oil may leak from an inspection cover on the front of the engine. Updated parts are available.
Due to uneven camshaft and rocker arm wear, lifters and rocker arms can be noisy, sounding like tapping coming from under the hood. The cam and all the rocker arms should be replaced.
