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.

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.
