CD changers, command units, voice control units, PSE units, and Tele Aid units are prone to failure, especially in early models.
The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.
The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.
The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

2006 Mercedes-Benz S430 Reviews
Its a great car!
I love my S430. I think the body styling as well as the sleek interior cannot be duplicated. It looks, both inside and out, more elegant than the new, more aggressive S series. It ages well, and with proper service and maintenance, it can be a dream to drive.
