Vehicle type is 2001 mercedes benz slk230 (r170 model). The inside rear view mirror is an electrochromic self dimming mirror that has no manual backup. The mirrors fail losing their ability to provide dimming against rear approaching headlights causing the driver to either be blinded or to have to turn the mirror up and have no rear view capability. I know of many documented cases of these mirrors failing including my own. Some fail by just quitting working while others leak the internal fluid.

The interior rear view mirror in my 2001 mercedes slk230 (r170 model) is an self-dimming mirror that has no manual backup. The mirror contained a fluid which leaked out, causing the self-dimming feature to fail. So basically, I'm blinded by approaching headlights whenever I drive at night. The only fix is to turn the mirror away and lose my rear view (which after all is the entire purpose of the rear view mirror!) I researched online and there are hundreds of documented cases of these mirrors failing in various makes and models. I contacted the oem mirror maker and their only suggestion was to have my dealer install a new mirror at a cost of $300-400. That is unacceptable.

My inside rear view mirror has failed. There is no manual backup. The fluid in the mirror, which causes the automatic self-dimming, has leaked out. The mirror now fails to provide dimming for rear approaching headlights resulting in a blinded driver or non-use; both eliminating rear view capability. The electrochromic self-dimming mirrors are standard equipment in my 1999 mercedes-benz slk 230, model r170. I have researched and found many documented cases of the exact mirrors failing in the same way. The mirror manufacture, magna donnelly, was replacing these mirrors for free under some kind of warranty program in the past, but stopped for unknown reasons. The problem has gotten so bad that their warranty department direct number (616‑786‑7495) now has a recorded message directing people to another web site that sells discounted replacement mirrors.

The mirror contains a fluid which is leaking out causing the self-dimming mirror to fail to dim against rear approaching headlights, resulting in the driver to either be blinded or to have to turn the mirror away. There are many documented cases of these mirrors failing in various makes and models as a result of the internal fluid leaking. The oem mirror maker has been contacted, and steve chenlo, from magna donnelly (his direct line is 616‑786‑7495), refused to take ownership of the problem. His advice was to purchase another mirror at approximately $200, and pay for installation, which was approximately $100 from the dealership. About a year ago, magna donnelly was replacing these mirrors for free but stopped for unknown reasons.
