Mercedes-Benz S430 4MATIC Problems

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.

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

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.

This is the worst car ever I am actually on my way to the shop. Where can i dump it. Since i bought this junk it has been one problem after another. Please do not buy this car

This car looks great yet has been a nightmare from day 1! wish I never bought it air suspension broke, radiator broke, cup holders are broken passenger vanity mirror broke, passenger mirror broke. This is luxury at its worst!

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.
