One problem related to interior rearview mirror has been reported for the 2003 Mercedes Benz 170. The most recently reported issues are listed below.
I have a auto dimming rearview mirror on my 2003 slk 230 that has become burry to look into due to a leakage of a chemical agent inside the mirror. The technology in the mirrors seem to be defective as there are many documented cases on this problem online by other mercedes owners.
