What 2014 Mercedes-Benz S550 owners say
Windows, wipers & sunroof
This vehicle was purchased new in 2014. The vehicle has a reverse tilt function feature on the right passenger mirror. When functioning properly, the right passenger mirror tilts downward and to the right when the vehicle is placed in reverse so that the driver can see all objects to the right rear of the vehicle (in the vehicle's blind spot). Once the vehicle is shifted into drive, the right mirror is supposed to return to the driver's (memory) setting position for the mirror so that the driver is able to see out of the right mirror when driving on the highway. The mirror on this vehicle fails to return to the driver's (memory) setting after shifting the vehicle into drive after being in reverse. The mirror remains in the downward and to the right position thus leaving the driver completely unable to see out of the mirror when driving on the highway. …

Steering
What component or system failed or malfunctioned, and is it available for inspection upon request? -Steering :Electrical Power Assist , Drive Shaft
According to the recall NHTSA campaign id number: 16V899000 and the vehicle inspection report from the local Mercedes dealership show as an identical issue. However, my vehicle is not identified as apart of the recall. The recall states the issue is due to the steering control unit not being soldered properly. Difficult to think this falls under normal wear and tear. I will get the repair done begrudgingly, though it would be nice if Mercedes would have stood behind its recall.
