2007 Mercedes-Benz S550 Problems

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.

I found the information RepairPal provided in the common problems section to be helpful and very timely. The common problems around the drivetrain is what I was experiencing and I've been given an estimate of approximately 9k to replace transmission and many other items. Please know an independent certified MB technician found this problem NOT the MB dealership!!! I ask how can a transmissio...

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.
