Mercedes-Benz S550 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz S550

The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.

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

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.

During production, on fifty-four Mercedes S-Class models, the front and rear door locks may have been mistakenly interchanged. This means that a rear passenger could open the rear door with a simple pull of the interior door handle, and the front passenger could not open by pulling on the interior handle. This situation could affect the safe exiting of the vehicle in a crash or protection against the accidental opening of the rear door by a child. Dealers will inspect the part numbers on all door locks and replace any that are incorrect. The recall began on March 27, 2009. The Mercedes-Benz recall number is 2009030001.
