Failure Date: 08/31/2005

2000 s500 instrument cluster began to fail after 58,000 miles, total failure of illumination occurred at 63,000 miles. In addition to all gauge failure, most importantly the speedometer, in door trunk release failed as well as the keyless remote for the trunk failed. Took vehicle to dealership, I was told by service that "good thing this didn't go bad on a sl500, it would cost you $7,500. 00. Yours is only $2,000. 00 dollars. " diagnosed as an electronic failure to the instrument cluster. The consequences were a speeding ticket on 11/17/05, I ran out of gas on the side of a very busy highway, and was nearly hit by another motorist on October 1, 2005.

6 Dash Wiring problem of the 2001 Mercedes Benz S Class

Failure Date: 08/01/2005

Vehicle is a 2001 s-500. Almost word for word the same issue(s) as odi id number : 10100807. Same car, same problems, same sentiment. Replacing fuses only results in flickering instrument cluster lighting, and even then the backlight is still non-functional. Gauge needles flicker as well, until they too go out completely. Fuses last only for a couple of days, whereupon the entire instrument cluster remains entirely black. Problem could be remedied simply by replacing faulty transistors, or redesigning an improperly laid-out instrument cluster, ie cooling the transistors much more adequately. This creates a tremendous safety risk by essentially creating an information black hole: the operator does not know his/her own speed, fuel level, if the parking brake is still on, if the directional signals are operational, if the check engine light is on, and other important information that mercedes is so keen on relaying only to the instrument cluster. The faulty instrument cluster has not yet created an accident, but it is only a matter of time until one of the other thousands of s-class owners runs out of gas on the highway, and gets into a collision all because he/she didn't know how much fuel they had.

7 Dash Wiring problem of the 2000 Mercedes Benz S Class

Failure Date: 09/17/2004

2000 mercedes s-430 blower motor fuse failure with gauge cluster problem(all gauages got stuck with blower motor fuse explosion at same time, I had fixed the blower motor fuse that was covered by mb's recall, but not the gauge) mb dealer said that was just the gauge problem but that happened at same time when the fuse went out(I was driving at 60mph and suddenly, all gauge stopped and some light does not turn on anymore). I heard that gauge cluster problem is a really common issue on S Class from the dealer and the gauge clusters are in back-order nationwide. Untill Dec. 2004 I guess there should be further investigation about this issue. . . This incident has great potential to an accident in certain situations.
