To who may this concerned, I have a 2003 mercedes Sl500 and recently found my battery control module caught on fire and burnt a section of my car. I have tried reaching out to mercedes directly first and they said the car is 20 years ago and it could have not be a manufactured defect. Please I need help this problem could’ve burn down my house or while I was driving. Mercedes requested I send them a letter in writing if I have to get the car inspected. Please setup and date so I can write them this is 100% liability on their brand as there is no schedule maintenance for a battery control module.
Sometimes when I start the car the lights on the dash will not come on and none of the gauges work ! then I turn it off and back on again and it works! also when I'm driving and hit a little bump on the freeway and road the dash lights turn red and says drive carefully then 2 seconds later goes back to normal!.

Started car and got message: "abc malfunction, car too low". In actuality, car elevated. The ride of the car has changed. It has a soft and floaty feeling compared to its normal stiffer ride. I have seen the above complaint on the internet multiple times. It seems this is a wide problem. I haven't heard any recalls from mercedes.
While driving to work, I was going about 35 mph when the dash lights up red saying "service brakes, stop vehicle, etc". My mechanic looked over everything to do with brakes and could not fix it. He called mercedes of tallahassee and was told it was an electrical issue that was a common problem with this vehicle. It did have a recall on it, but it expired in July last year, just my luck. So I googled it and have now found tons of people with the same experience! how can the vehicle safety administration legally allow Mercedes Benz to continue letting this happen to people? how many accidents must take place, or god forbid deaths before something is done? I have no option but to pay out of pocket to have this piece of $100k junk fixed and pray it never happens again! Mercedes Benz and the vehicle safety administration better pray this doesn't cause an accident or I will sue the [xxx] out of both! information redacted pursuant to the freedom of information act (foia), 5 u.
