While driving at approximately 45 MPH my instrument panel went black. I could not determine my speed, time of day fuel usage, miles traveled, or signal lights. I did not buy the vehicle from a Mercedes dealer. I called a dealer about a recall. He stated that there was a recall but it had expired. I understand a recall expiring, but it seems that Mercedes benz would support their product no matter when the defect occurred. It is a safety issue that could have caused running out of fuel without being able to detect it and no way of being aware of the speed of the vehicle. The signal lights don't function on the cluster. I believe it was a defect that Mercedes benz was aware of and that they should replace the instrument cluster at no cost to me. The cost to replace the instrument cluster is

Polycarbonate headlight lenses, recently substituted for glass by manufacturer, become blackened and occluded over time, rendering headlamps increasingly ineffectual and making night time driving dangerous. This material is unsuited for the purpose of shielding the headlamps and should be replaced in all instances by materials that do not degrade during their intended use. *tr

Mercedes benz s 500 had total brake failure. Vehicle has about 12,000 to 14,000 miles on it. Dealer is trying to blame brake failure on rust on rotors due to lack of use of vehicle. I don't think the manual warns about this. Sounds like a make up story to me. I have had Mercedes vehicles for about 30 years and never had a problem like this before. Brake failure caused an accident but since at very low speed no injuries. If it had happened at a high speed it could have LED to serious injuries or death. *nm
