The contact stated that his daughter was able to drive the vehicle since the exterior lights were working properly. The vehicle was taken to the dealer who diagnosed that the instrument cluster had failed and needed to be replaced. The contact stated that the failure had been reoccurring while driving. The contact referenced NHTSA Campaign Number: 06V028000 (Interior Lighting). The manufacturer was notified of the failure and informed the contact that an extended warranty had been issued for the failure but had already expired. The vehicle was not repaired.

WE PURCHASED OUR 2001 MERCEDES S-500 USED. EVERYTHING RAN FINE. AFTER RUNNING IT THROUGH AN AUTO CARWASH WITH A UNDER BODY SPRAY, THE ELECTRICAL SYSTEM WENT HAYWIRE. I NOTICED THAT THE FRONT PASSENGER FLOOR WAS SOAKED. ELECTRICAL MALFUNCTIONS INCLUDED NON FUNCTIONING LOCKS, WINDOWS, AIR, ALL LIGHTS FLICKERING, SEAT CONTROLS, HORN, HAZARD LIGHTS, SUNROOF, DASH CONTROL, VIRTUALLY EVERYTHING ELECTRICAL. THESE MALFUNCTIONS OCCURRED WHILE THE CAR WAS IN MOTION AND WHILE PARKED. WHEN WE TURNED THE KEY OFF AND REMOVED THEM, THE CAR CONTINUED TO RUN. WE DISCONNECTED THE BATTERY AND THE CAR CONTINUED TO RUN STILL FOR AN ADDITIONAL 5 MINUTES. AFTER DOING SOME RESEARCH ONLINE, WE HAVE DISCOVERED SIMILAR COMPLAINTS WITH THE SAME SITUATIONS INCLUDING PASSENGER FLOOR BEING SOAKED RESULTING IN ELECTRICAL FAULTING. (SEE ATTACHED PICTURE) COMPLAINT BELOW MENTIONS A STUPID REPAIR KIT AT OWNERS COST MEANING MERCEDES IS AWARE OF THIS DANGEROUS POSSIBLY DEADLY FAULT IN THEIR VEHICLES.

VEHICLE STALLED TO DEAD THREE TIME, ONE ON AN INTERSECTION. SYMPTONS STARTED WITH ROUGH IDLE, MISFIRING AND STALL. AFTER INSPECTION OF UPPER WIRING HARNESS (RECOMMENDED BY A FRIEND) THE CONCLUSION WAS BARE AND DESINTEGRATED WIRES CAUSING SHORT CIRCUITS EVERYWHERE IN THE CAR, PUTTING ME AND MY FAMILY AT RISK. IT IS AN EXPENSIVE REPAIR AND I CAN'T DRIVE THE CAR UNTIL MBUSA GIVES A SOLUTION WHICH I'VE HEARD THEY LOOK LIKE UNAWARE. I OWNED OTHER MERCEDES MODELS AND WE ALWAYS HEAR THAT THIS W140 SERIESWERE THE BEST CAR IN THE WORLD. BUT THIS ISSUE COULD HAVE COST MY LIFE.

ELECTRONIC DASH INSTRUMENT CLUSTER WENT BLACK AND THE SPEEDOMETER COULD NOT BE SEEN AND ALL OTHER DRIVER INFORMATION ON THE REMAINING GAUGES WERE ALSO NOT VISIBLE.

TAKATA RECALL. I WAS RIDING MY VEHICLE WHEN ALL OF A SUDDEN THE INSTRUMENT CLUSTER WENT HAYWIRE. I THOUGHT IT WAS BATTERY BUT IT WASN'T THE CAUSE IT DRAINED 4 BATTERIES I HAD ON WARRANTY AND 1 I HAD TO PURCHASE. I FOUND OUT THE INSTRUMENT CLUSTER DRAINS THE BATTERY AND LOSS OF POWER. I REACHED TO A MECHANIC AND HE LET ME KNOW THAT THE INSTRUMENT CLUSTER IS CAUSING THE POWER LOSS AND NEEDED TO BE REPLACED. I DID SOME RESEARCH AND REALIZE THEIR WAS A RECALL FOR THE INSTRUMENT CLUSTER FOR THIS DEFECT. THIS DEFECT COULD HAVE A SERIOUS INCIDENT IF WASN'T PROPERLY AWARE. I WOULD TO HAVE A RECALL IF POSSIBLE.

I JUST BOUGHT MY MERCEDES S500 TWO WEEKS AGO. IT ONLY HAD ONE OWNER, 98,000 MILES AND GOOD CAR FAX. I WAS PULLING OUT OF MY DRIVEWAY AND NOTICED THE DASHBOARD LIGHTS WERE COMPLETELY DARK AND ALL OF THE GAUGES WERE NOT WORKING!! I CANT TELL HOW MUCH GAS I HAVE NOR HOW FAST I AM DRIVING! I RESEARCH TODAY AND FIND THAT THERE WAS A RECALL ON THIS ISSUE THAT IS NOW EXPIRED. HOW AND WHY DOES A RECALL EXPIRE??!! THIS IS A MAJOR SAFETY ISSUE. I WONT BE ABLE TO DRIVE AT NIGHT, I HAVE CHILDREN TO TRANSPORT AND I DON'T WANT TO GET INTO A ACCIDENT OR RECEIVE A TICKET FOR DRIVING TOO FAST! ITS SO UNFAIR THAT I JUST PURCHASED THIS CAR AND WAS NOT AWARE OF A RECALL. HOW IS THIS FAIR TO A BUYER WHO WOULD HAVE NO KNOWLEDGE OF THIS!!! SO I GUESS IF ME AND MY CHILDREN GOT INTO AN ACCIDENT AND DIED, MERCEDES WOULD SAY "OH WELL, THE RECALL EXPIRED". BULLSHIT!!! I AM SO ANGRY. AND THEY DON'T CARE!!!!

ONE NIGHT WHILE I WAS DRIVING, SUDDENLY THE DASHBOARD LIGHT SLOWLY DIM, FLICKED, AND 95% LIGHTS WERE SHUT OFF INCLUDED SPEEDOMETER, THE REST WERE VERY DIM HARDLY SEE ANYTHING. INSIDE MY CAR WAS TOTALLY DARK AT THAT POINT, I ALMOST GOT INTO AN ACCIDENT. IMMEDIATELY, I HAD TO STOP ON THE SIDE OF THE ROAD. THAT WAS VERY SCARY!! DUE TO THIS KIND OF DEFECTIVE, THE CAR IS NO LONGER IN DRIVING CONDITION AT NIGHT. THIS CAR IS ONLY 90K MILE. AFTER THIS INCIDENT, I SEARCHED ON THE INTERNET AND I HAD FOUND FEW FORUMS DISCUSSED ABOUT THE SIMILAR PROBLEM WITH S500. BUT I COULD NOT FIND ANY RECALL FOR MY CAR WHICH RELATED TO THIS SAFETY ISSUE IN NHTSA. THIS IS A SAFETY CONCERN. THIS WAS ALMOST CAUSED MYSELF GETTING INTO AN ACCIDENT. WOULD YOU PLEASE REVIEW THIS SAFETY MATTER. GREATLY APPRECIATED.

NHTSA complaint #10954983 — an unverified report by a vehicle owner.
ELECTRICAL SYSTEM
I WAS AT A STOP LIGHT ON 225 AND CHAMBERS AND WHEN THE LIGHT TURNED GREEN AS SOON AS A HIT THE GAS MY ENTIRE DASHBOARD WENT BLANK. I NO LONGER HAD LIGHT AND MY GAUGES WERE NOT RESPONDING EITHER. AFTER DOING SOME RESEARCH I SEEN SOME FORUMS ABOUT THE RECALL SO I CALL THE MANUFACTURER AND WAS TOLD THAT EVEN THOUGH ACKNOWLEDGED AS A SAFETY CONCERN THE RECALL WAS CLOSED JUNE 2011. I PURCHASED THE CAR JUNE 2010 AND NO ONE REACHED OUT. I HAVE ONLY ONE CAR AND I CAN NOT DRIVE IT BECAUSE I CANT SEE THE SPEED OR IF I EVEN HAVE GAS. I HAVE KIDS AND LIKE EVERYONE ELSE I WORK BUT I CAN NOT AFFORD TO PAY $1800.00 TO FIX THIS AND I SHOULDNT HAVE TO. I CANT UNDERSTAND HOW A SAFETY RECALL CAN EXPIRE. SEEMS AS IF THERE IS NO TRUE REGARD TO SAFETY.
