2003 Mercedes-Benz S-Class Electrical System Problems

ELECTRICAL/FUSE/CLUSTER PANEL LIGHTS ARE OUT IN DASH VEHICLE WAS STATIONARY

I HAVE A 2003 MERCEDES S430. THE OTHER DAY MY WIFE WAS GOING DOWN THE HIGHWAY AT 65 MPH WHEN IT JUST SHUT OFF IN THE MIDDLE OF THE ROAD. THIS IS VERY DANGEROUS. HOW DO WE ALLOW A VEHICLE TO OPERATE ON THE HIGHWAY THAT WOULD JUST CUT OFF IN THE MIDDLE OF THE ROAD WITHOUT AT LEAST GIVING YOU A CHANCE TO GET OUT OF THE ROAD. THANKS

WHILE DRIVING GETTING READY TO ENTER THE HIGHWAY MY 2003 MERCEDES S430 INSTRUMENT PANEL WENT OUT. THE GAUGES GOT STUCK ON WHAT THEY WERE WHILE DRIVING. I WASN'T ABLE TO SEE ANYTHING ON THE PANEL. I TOOK IT TO THE NEAREST SHOP AND THEY CHANGED THE FUSE, HOWEVER THE FUSE BLEW RIGHT BACK OUT EACH TIME THEY CHANGED IT. THE CAR WAS STILL DRIVABLE. I HAVEN'T HAD THIS CAR FOR 1 YEAR YET AND I AM LOST AT WHAT TO DO. THE SHOP SAID THE INSTRUMENT CHAISE WILL WORK BUT SOMETHING IS BLEWING THE FUSE. I WAS ALSO TOLD THAT THE ALUMINATOR IN THE INSTRUMENT PANEL IS FAULTY AND NEEDS TO BE REPLACED. ANY HELP WITH THIS ISSUE IS HELPFUL.. PLEASE HELP AS THIS CAR HAS BECOME A NIGHTMARE (INSTRUMENT PANEL, DOORS DON'T LOCK, PASSENDER SEAT MOVES AT WIERD TIMES, AND THE AIR STRUT BUSTED) INSTEAD OF A GOOD DREAM. I HAVE READ A NUMBER OF ISSUES WITH THE INSTRUMENT PANEL FAILURE IN THESE CARS. I WISH I WOULD OF SEEN THIS BEFORE I PURCHASED IT. MERCEDES NEEDS TO COVER THE COST IN FIXING THIS ISSUE.

SPECIAL ACQUISITION MODULE (SAM) MY CAR WOULD NOT START THE MERCEDES ROADSIDE CAME OUT AND STARTED THE CAR AND I TOOK IT TO THE DEALERSHIP FOR DIAGNOSTIC. UPON REVIEW THE DEALER STATED THE SAM MODULE PLASTIC COVER HAD WATER DROPS ON IT. THEY ALSO STATED THE MALE AND FEMALE CONNECTORS TO THE MODULE WAS CORRODED, AND I WOULD NEED A NEW SPECIAL ACQUISITION MODULE (SAM) AT THE COST OF $1590.00. THEY ASK IF I HAD LEFT THE WINDOWS DOWN, BUT I HAD NOT THE INSIDE OF THE CAR HAS NEVER BEEN WET, BUT I DID NOTICE EVERYTIME I WENT TO THE CAR WASH THE INFORMATION SYSTEM WAS SHOWING ALERTS I DIDN'T RECOGNIZE. MY CONCERN IS EVEN WITH A NEW MODULE IF THE OLD ONE GOT WET AND IT IS CLEAR THE WATER IS COMING FROM UNDERNEATH THE CAR WHAT WILL KEEP THE NEW MODULE (SAM) FROM GETTING WET. SOMETHING IS ALLOWING THE (SAM) MODULE TO GET WET FROM UNDER THE CAR. *TR

TL* THE CONTACT OWNS A 2003 MERCEDES BENZ S430. THE CONTACT STATED THAT THE VEHICLE WAS EMITTING SMOKE OUT OF THE TRUNK AND HE COULD SMELL BURNING PLASTIC. THE CONTACT ALSO STATED THAT THE A PSE PUMP CONTINUED TO RUN AFTER THE VEHICLE WAS SHUT OFF, CAUSING IT TO OVER HEAT AND MELT THE WIRING HARNESS. IN ADDITION, THE CONTACT STATED THAT HE HAD TO DISCONNECT THE PUMP FROM THE WIRING HARNESS IN ORDER TO STOP THE SMOKING.

A FEW DAYS BEFORE THE MAIN INCIDENT, MY 2003 MERCEDES S430 WOULD STALL FOR NO APPARENT REASON. I CALLED MERCEDES ROADSIDE ASSISTANCE, AND THEY TOLD ME THAT I SHOULD LET THE CAR RESET, AND THIS WOULD FIX THE PROBLEM. THIS HAPPENED TWO TIMES AND BOTH TIMES THERE WAS A TEMPORARY FIX AFTER THE CAR RESET. A DAY AFTER THE SECOND RESET, MY CAR COMPLETELY STALLED AND ENGINE SHUT OFF COMPLETELY WHILE I WAS DRIVING ON THE FREEWAY CAUSING ME TO ALMOST GET INTO A FEW CRASHES. MERCEDES ROADSIDE ASSISTANCE CALLED THE TOW COMPANY, AND THEY TOOK OVER AN HOUR AND A HALF TO GET THERE. IT WAS A VERY HOT DAY, AND I FELT VERY SICK FROM THE HEAT. THE CAR WAS TOWED, AND IT TURNS OUT THAT THE CRANK SENSOR WAS FAULTY AND NEEDED TO BE REPLACED. ROADSIDE ASSISTANCE DID NOT TELL ME IT NEEDED TO BE REPLACED, BUT JUST TO LET THE CAR RESET. THERE WAS NO WARNING THAT THE SENSOR WAS FAULTY. THERE WERE NO LIGHTS THAT CAME ON THE DASHBOARD THAT THE SENSOR WAS FAULTY. THIS IS AN INHERENTLY DANGEROUS DEFECT, THAT A SENSOR GOES BAD WITH NO WARNING, AND THE ENGINE SHUTS OFF. THE SENSOR WAS REPLACED BY MERCEDES FOR $433.16. I AM TRAUMATIZED BY THE INCIDENT, AND I AM SCARED TO DRIVE A DANGEROUS CAR THAT CAN SHUT OFF WITH NO WARNING WHILE DRIVING FOR SOMETHING AS SMALL AS A BAD SENSOR. FURTHER, I WAS MISLED BY MERCEDES ROADSIDE ASSISTANCE THAT THE PART NEEDED TO RESET, RATHER THAN BE REPLACED. *TR

TL* THE CONTACT OWNS A 2003 S430 MERCEDES BENZ. THE PLASTIC COVER FOR THE HEAD LIGHT BULB MELTED . THE DEALER CONTACTED THE MANUFACTURER REQUESTING ASSISTANCE WITH THE REPAIR COST OF $500.00.

SHE TOOK THE VEHICLE BACK TO THE DEALER, BUT THE TECHNICIAN WAS UNABLE TO DETERMINE THE CAUSE OF THE FAILURE. ADDITIONALLY SHE CANNOT READ ANY OF THE GAUGES OR DISPLAY ON THE INSTRUMENT CONTROL PANEL. THE FAILURE AND CURRENT MILEAGES WERE 1,700. UPDATED 1/25/10 *CN THE CONSUMER WAS INFORMED THAT THE PLASTIC MELTING ON BOTH HEAD LIGHTS WAS A FACTORY DEFECT. AFTER THE INSTRUMENT PANEL WAS INSTALLED, THE BATTERY CONTINUED TO DIE. UPDATED 01/26/10

MY CAR IS HAVING ELECTRICAL MALFUNCTIONS. THE INTERIOR LIGHTS INSIDE MY CAR ARE MALFUNCTIONING. THE LIGHTS ON MY DASHBOARD ARE MALFUNCTIONING. I CAN'T SEE HOW FAST I'M DRIVING BECAUSE I CAN'T SEE THE SPEEDOMETER. THIS IS VERY UNSAFE FOR ME. WHEN THE ELECTRICAL MALFUNCTIONS OCCUR, NOTHING ELECTRICAL, LIGHTS, SEATS WORK IN THE CAR. *TR

MY 2003 MERCEDES S500 HAS TWICE ELECTRONICALLY SELF-CLOSED IT'S TRUNK ON TWO SEPARATE USERS, ON TWO SEPARATE OCCASIONS. THIS VEHICLE HAS BEEN TAKEN TO TWO SEPARATE MERCEDES DEALERS FOR THE PROBLEM. ONE OF THOSE DEALERS REPLACED A NUMBER OF PARTS. DESPITE DOING SO, THE SECOND OCCURRENCE (LAST NIGHT), LEFT MY OTHER HALF IN TEARS, PAIN, WITH A RECESS IN HER HEAD AND A HEADACHE. THE ELECTRONIC TRUNK LID HAS HAD INSTANCES WHERE IT DOES NOT OPEN ALL THE WAY, DOES NOT CLOSE ALL THE WAY, OR A COMBINATION OF THE TWO. THEN THERE IS THE MORE SERIOUS AND I BELIEVE POTENTIALLY LIFE TREATING, UNPROVOKED, UNEXPLAINED AND AS YET UN FIXED ELECTRONIC CLOSING THAT HAS TWICE OCCURRED WHEN PUTTING IN OR REMOVING GOODS FROM THE TRUNK. I WOULD FIND IT HARD TO BELIEVE THAT I AM THE ONLY OWNER WHO HAS HAD SUCH A PROBLEM. THE METAL TRUNK LID COMES DOWN WITH FORCE STRIKING DIRECTLY ON THE TOP OF AN ADULTS HEAD. IT IS UNKNOWN WHAT IT WOULD DO TO A NON-ADULT. I HAVE SPOKEN TO A REPRESENTATIVE FOR MERCEDES WHO STATES TO HER KNOWLEDGE THERE IS NO PROBLEM AND THAT THEY WOULD BE HAPPY TO GET THE CAR IN AND ATTEMPT TO FIX IT, BUT CAN NOT GUARANTEE THEY CAN. THE FIRST TIME IT OCCURRED, IT HIT ME AND NEARLY KNOCKED ME OUT. AFTER BRINGING THE CAR IN I ASSUMED IT WAS FIXED, HOWEVER, AFTER LAST NIGHT, IT CLEARLY IS NOT. THOUGH I CAN NOT MAKE IT PERFORM UPON COMMAND, I HAVE NO REASON TO BELIEVE IT WILL NOT OCCUR AGAIN. *JB

I WAS DRIVING ON A HIGHWAY WHEN CAR JUST STOPPED. I HAD TO GET OUT OF THE CAR AND PUSH IT FOR IT TO START AGAIN. AFTER 500 IT STOPPED AGAIN AND HAD TO BE TOWED AWAY. *JB

THIS AUTO'S COMMAND (COMMUNICATIONS) SYSTEM (RADIO/CASS/CELL PHONE/NAVIGATION SYSTEM) HAS FAILED, INTERMITTANTLY ELEVEN TIMES OVER THE PAST 2 YEARS. SINCE I PURCHASED THIS AUTO FOR MONTHLY TRIPS BETWEEN MAINE AND GEORGIA, I REALLY NEED SAFE AND CONSISTENT COMMUNICATIONS AND NAVIGATION SYSTEMS TO OPERATE PROPERLY. I'VE NOW LOST FAITH IN THE SAFE OPERATION OF THIS VEHICLE; PURCHASED EXPRESSLY FOR SAFE, LONG DISTANCE, ALL-WEATHER, & DEPENDABLE TRIPS OF 2,600 MILES EACH MONTH. WHILE THE FACTORY HAS ATTEMPTED TO REPAIR/REPLACE THE COMMAND SYSTEM TEN TIMES, IT HAS NOW FAILED FOR THE ELEVENTH TIME! THIS PROBLEM HAS BEEN ADDITIONALLY DOCUMENTED IN THE PAST THREE ISSUES OF THE STAR: MERCEDES BENZ OWNERS CLUB MAGAZINE. *AK
