The auto dimming rear view mirror turned black and I cannot see out of it dealer wants like $800 to replace it. There are many people on the forums with the same problem, also the auto dimming drivers side mirror has a similar problem and can't see out of that either, again many people on the forums complain about this too. At one time the manufacturer of the mirror was sending free replacements since there were some quality control problems, but no more.

Visual impairment due to "lava lamp/ distorted bubble" effect in auto-dimming rearview and side mirror. I never realized so many other people were having this problem and didn't realize that this website existed. I would have filed my complaint a long time ago. I've never heard of replace a rearview mirror before. One day I was driving and I noticed there was a bubble in the middle of my tiny mirror. It kept getting larger and didn't go away on its own. Naively, I thought it was just the outside humidity but I should have known better. This mirror costs way too much for the terrible performance.

The inside rear view mirror in my 2002 mercedes-benz slk32 is a self-dimming mirror that has malfunctioned. The mirror contains some kind of fluid that leaked out onto my center console and then the dimming effect no longer worked, leading to an unsafe condition at night. There is no manual backup with this mirror, it is electric and once it fails, it stops working. I feel mercedes-benz should issue a recall on cars containing these mirrors and replace them.

2002 mercedes slk320 fails to accelerate randomly and at critical moments. Gas pedal can be pushed all the way to the floor but the car remains at idol so the car doesn't have enough power to get out of the way of oncoming traffic. No warning or check engine diagnostics are generated. Power is slow to recover but leaves the car limping along at idol until it responds again. Several owners have said that they had to replace the pedal position sensor or the entire gas pedal assembly to correct the problem. This can cost $100 to $400 each time the problem happens. The unplanned operational flaw can cause an accident when the car randomly will not accelerate. I personally have had several near misses when merging or turning in to traffic only to find myself limping in front of a large SUV bearing down on me. There is a 5 second or more lag until the car starts to respond again. Response doesn't come on right away but slowly ramps up to the needed speed.

I bought a slk 320 2002 model and while driving the right side brakes so violently the tires squeal, I am afraid to get on an interstate, and reading a lot of reviews I see I am not the only one. This is a tremendous safety concern.

The inside rear view mirror in my 2002 mercedes-benz slk 230 (r170 model) is an electro chromic self-dimming mirror that has no manual backup. The mirror contained a fluid which leaked out causing the self-dimming mirror to fail to provide dimming against rear approaching headlights resulting in the driver to either be blinded or to have to turn the mirror away which greatly eliminates rear view capability in the interior. There are many documented cases of these mirrors failing in various makes and models as a result of usually from the internal fluid leaking.
