The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.

I have not had this problem fixed. I was wondering if anyone out there had the same problem. I can't get the trunk to open using the key or the remote.

Mercedes-Benz S430 Reviews
This model, like all MBs, are pieces of garbage. Also owned a C-Class. Continuous failures which include repeated failures: Airmatic, front end rebuilding issues, numerous electrical failures.
These cars are poorly engineered, designed to be cost prohibitive.
DO NOT BUY ONE OF THESE OR ANY MB PRODUCT. YOU WILL REGRET IT.
worst car ever,lots of problem all the time, been to repair shop often
I have had my 2001 S40 with AMG accents for 2 years now. Drives very smoothly and lots of compliments on it's looks no problems with the engine or AC the only chalenges are the LED lighting turn signal in mirror which causes an error message on the dash board apparantley the whole mirror housing must be changed to fix plus the lighting on the dashboard malfunctioned and turned off. Had a good Mercedes serviceman and he took it to a diagnostics center who fixd for about $400 other than that very happy with my purchase and regular maintenane costs are about the same as epected for any high end vehicle...
I have major suspension problems and the trunk looks open all the time.I have had to repair the suspention/ air shocks 3 times at $4,500 a whoop! There should have been a recall on the suspension system it is dangerous and costly. I have broken down 3 times with my car sitting on the street like a lower rider, SHAME ON MERCEDES
BENZ
Crap crap crap. this is the worst car I have ever owned. Every 3-4 months its another trip to repair shop. I think I have funded his new boat. Cranks sensor, SRS error, random noises in front suspension, a/c not working, sun roof error won't auto open/close. The list goes on and on. Never a MB again.
