2003 Mercedes-Benz SL500 Electrical Problems

To who may this concerned, I have a 2003 Mercedes SL500 and recently found my battery control module caught on fire and burnt a section of my car. I have tried reaching out to Mercedes directly first and they said the car is 20 years ago and it could have not be a manufactured defect. Please I need help this problem could’ve burn down my house or while I was driving. Mercedes requested I send them a letter in writing if I have to get the car inspected. Please setup and date so I can write them this is 100% liability on their brand as there is no schedule maintenance for a battery control module.

2003 MERCEDES BENZ SL 500. CONSUMER WRITES IN REGARDS TO POSSIBLE FATAL FLAW IN VEHICLE. *SMD THE CONSUMER STATED, AS HE WAS BACKING OUT OF HIS DRIVEWAY, HE APPLIED THE BRAKE AND THEY FAILED. A RED LIGHT AND A SIGN INSTRUCTED HIM TO OBTAIN IMMEDIATE SERVICE. THE MECHANIC, KEPT THE VEHICLE FOR A WEEK, BUT WAS UNABLE TO ANYTHING WRONG WITH THE BRAKES. AT THE MECHANIC'S SUGGESTED, THE VEHICLE WAS TOWED TO THE DEALER. AFTER THE VEHICLE WAS THERE FOR A FEW DAYS, THE DEALERSHIP CALLED AND SAID THE PROBLEM WAS THE BATTERY HAD DIED. IT WAS A SECONDARY BATTERY WHICH SUPPLIED POWER TO EVERYTHING THAT CONSUMED ELECTRICITY, INCLUDING THE BRAKES IN HIS MODEL AND YEAR VEHICLE. SO, IF IT FAILED, SO WOULD THE BRAKES. *JB

WHILE DRIVING TO WORK, I WAS GOING ABOUT 35 MPH WHEN THE DASH LIGHTS UP RED SAYING "SERVICE BRAKES, STOP VEHICLE, ETC". MY MECHANIC LOOKED OVER EVERYTHING TO DO WITH BRAKES AND COULD NOT FIX IT. HE CALLED MERCEDES OF TALLAHASSEE AND WAS TOLD IT WAS AN ELECTRICAL ISSUE THAT WAS A COMMON PROBLEM WITH THIS VEHICLE. IT DID HAVE A RECALL ON IT, BUT IT EXPIRED IN JULY LAST YEAR, JUST MY LUCK. SO I GOOGLED IT AND HAVE NOW FOUND TONS OF PEOPLE WITH THE SAME EXPERIENCE! HOW CAN THE VEHICLE SAFETY ADMINISTRATION LEGALLY ALLOW MERCEDES BENZ TO CONTINUE LETTING THIS HAPPEN TO PEOPLE? HOW MANY ACCIDENTS MUST TAKE PLACE, OR GOD FORBID DEATHS BEFORE SOMETHING IS DONE? I HAVE NO OPTION BUT TO PAY OUT OF POCKET TO HAVE THIS PIECE OF $100K JUNK FIXED AND PRAY IT NEVER HAPPENS AGAIN! MERCEDES BENZ AND THE VEHICLE SAFETY ADMINISTRATION BETTER PRAY THIS DOESN'T CAUSE AN ACCIDENT OR I WILL SUE THE [XXX] OUT OF BOTH! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
