Mercedes-Benz S430 4MATIC Problems

Airmatic Pump Motor May Fail Due to Sticking Relay

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.

The Differential May Develop Leaks From the Seals or Cover

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.

Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor

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

Mercedes-Benz S430 4MATIC Reviews

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.
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
