Mercedes Benz 1999 slk 230 -rear view mirror failed, the inside rear view mirror is an electrochromic self dimming mirror that has no manual backup. The mirrors are completely useless. 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. Both inside and driver side mirrors have failed. There is no way one can see - this is a real safety issue - Mercedes dealer and Mercedes usa say they have never heard of such a problem - dealer says it is normal wear. Theses are mirrors - not tires. Company that made the mirror has been aware of the problem for years since they offered replacements previous years.

This is a report about unusual fogging up of all vehicle windows if the A/C is switched off while driving. This makes the car undriveable without A/C being on all the time or having to open windows due to lack of visibility through the windshield. If, for some reason, the A/C malfunctions while driving, this could pose a dangerous situation if people don't realize what happened quickly. This is very similar to what happens if one drives with the climate control on recycle instead of allowing fresh air in cold climate. But in this case, it is fogging up regardless of the temperature/humidity outside and even when the climate control is not on recycle mode. The car has a fresh/recirc flap inside the dashboard automatically controlled by a flap actuator. If this part fails, as I suspect it has happened, then the flap can get stuck in recirc mode which no fresh air will ever enter the car when windows are closed. Even if A/C is on to prevent fogging, driving with no fresh air coming in can be dangerous as carbon dioxide builds up inside from breathing leading to sleepiness in the driver (which is why driving for long with recirc air is not recommended). The problem is that this is a silent malfunction, and other than the fogging problem, there is no other indication. I have taken this to the dealer and they say they cannot reproduce the problem. But I can reliably reproduce this within 3 minutes of driving with A/C off. There is no recourse left for me to get this problem fixed and driving this way if there is no fresh air coming is dangerous to me and to others on the road.

The inside rear view mirror in my 1999 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. The leak discolor the mirror which make visibility poor.

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.

Rear view mirror failure on 1999 Mercedes Benz S320. Mirror is an auto dim rear view mirror and view is obstructed because liquid crystal material is "leaking" out of mirror. This is a design and quality issue that would not occur with a standard rear view mirror. There is no manual failover on mirror so the vehicle can be driven safely in the event of a failure. Magna donnelly corporation willfully and knowingly produces a defective product sold to thousands of oems and now refuses to repair their defective products. Previously this company replaced the defective mirrors and now they refuse.

In the resent month I noticed my rearview mirror on the inside to appear to be leaking. It also has stopped dimming. Everything I see from my mirror appears very foggy and hard to see. It difficult to back up looking through it. The mirror never works properly since this "leaking" has happened. I have not done anything to fix this problem yet. The oem mirror is $180 at the Mercedes dealer.
