2009 Mercedes-Benz S550 Problems

Heating & Air Conditioning -- Verified

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.

Engine -- Verified

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

Engine -- Verified

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Drive Train -- Verified

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.

Brakes -- Verified

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.

Body, Interior & Misc., March 27, 2009

RepairPal Expert Overview:

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.
