2005 Mercedes-Benz S430 4MATIC Problems

Drive Train -- Verified

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.

Suspension & Steering -- Verified

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.

Engine -- Verified

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Suspension & Steering -- Verified

Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.

Heating & Air Conditioning -- Verified

Due to wear of mechanical parts in the control head, the buttons on
temperature control assemblies work erratically or not at all. These
control heads need to be replaced for this concern or when the display
screen starts to fade out.

This is my second benz and it is an all around driving machine. On long or short trips it is super to drive.
Only thing is the dealerships really charge a lot for maintenance.
