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 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.

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

When I purchased my 2008 S550, I understood that repairs and parts were most expensive than Japanese or American vehicles. What surprised me was the number of parts that failed. At 45K my front tie rod bushings failed (upper and lower). Although it wasn't a ton of money it was cause for concern. Rear tires require replacing every 10K miles (this was expected) but the cost of the tires hurt. HV/...

My 2007 S550 has been nothing but a money pit! I just had to pay $7,000 for a new transmission and it still feels like it's going to stop when it's idling. I have put in well over $25,000 in repairs.
