2 Vehicle Speed Control problem of the 2000 Mercedes Benz S500

Failure Date: 11/09/2020

Last night we had tropical storm eta in florida. We had about 10 inches of rain. The temperature was between 70f and 80f. The car was parked on high ground but in the rain. The inside of the car flooded with water under the carpet. I have not determined the source of the leak or the source of the short yet but the car is in my shop. I drilled holes in the floor to drain the water for now. The entire electrical system went crazy. The abs was malfunctioning, the wipers were turning on and off, the brake lights and other lights were turning on and off on there own, the car stayed running with the key out of the ignition, the lights would turn on and off with the key out of ignition, the sos light was turning on and off, the airbag light was turning on and off, the speakers were popping, the throttle controls were acting odd and not corresponding with the throttle control, they would not respond or stay on longer than normal, the transmission was getting stuck in gears, the air suspension was acting weird, I pressed the trunk release and the tail lights started flashing, the gas gauge read empty and I had a full tank, the speed and rpm were working normal, outside temp was going on and off as well as the clock, the ac blower speed was changing and turning off, the windows would work then not work, the interior lights were turning on and off, basically the car would start and run but almost every system in the vehicle was malfunctioning. This is the second mercedes I have owned that did this. I took videos but they were too big to share.

When driving my car makes noises like I'm pulling a trailer and I'm not. . In July my right shock went out so I repaired it. . Then prior to that the alternator was detected so I repaired that and just last week my instrument cluster went out. My suspension is really messed up and I can't shift at all.

4 Vehicle Speed Control problem of the 2001 Mercedes Benz S500

Failure Date: 03/15/2015

While driving on the freeway, the back lights in the instrument cluster that illuminate the speed markings started to flicker for a few seconds and then turned off and went dark. Then after a few minuets, the whole instrument cluster went dark and the speedometer stopped working completely. It was impossible to know what speed you are going at.

5 Vehicle Speed Control problem of the 2001 Mercedes Benz S500

Failure Date: 08/10/2014

While driving on a 400 mile trip home in the dark, the entire cluster lighting turned off and speedometer began to fluctuate. The situation was extremely hazardous and I was forced to pull over on a major highway to find out what is wrong. As no fuses or relays were blown out, I had to use a small flashlight to illuminate the cluster to get home.

6 Vehicle Speed Control problem of the 2006 Mercedes Benz S500

Failure Date: 12/24/2013

My transmission would not shift out of second gear. I turned it off and back on and it did not clear. I got a "pre-safe unavailable" message. I did some research and learned this is a "transmission control module" failure. It is very unsafe in that the car cannot keep up with traffic and is a danger to myself and others.

7 Vehicle Speed Control problem of the 2001 Mercedes Benz S500

Failure Date: 10/01/2012

I was driving the vehicle on the highway when all of a sudden the entire dash gauge cluster flickered and went totally dark and stopped working. I was so distracted that I almost ran into the car that was in front of me. The interior lighting went out as well. Now, there is no way of knowing the speed of the vehicle or of seeing any of the other important gauges including gear selection. It is impossible to drive the car safely. The mercedes dealer in manhattan and north America mercedes center in NJ says the car is not covered and that the extended warranty for this issue has expired. They have basically said" too bad" for me in a very arrogant and cold manner. Almost like I should be ashamed for asking them to fix it. This is a low miles well cared for vehicle that has always been pampered and garaged. It belonged to my father. The estimated repair price from the dealer for the instrument cluster is over $4,000. 00. The car is currently sitting in my garage unable to be driven. Frankly, I am surprised at mercedes' refusal to fix the car considering that there was a national recall concerning this very issue and that also there was a need for a mb extended warranty to fix this very same lighting/cluster issue. Not to mention the exorbitant price for the S500 both retail and when it was new. I expected when I purchased the car that it would provide the type of reliability and engineering that mercedes claims to have built it's reputation on.
