2010 Mercedes-Benz S-Class Electrical System

THE COMPUTER CONTROL UNIT FOR THE HYBRID MOTOR HAS FAILED ON MY AND MANY S400S. THIS CAUSES CAR TO STALL OUT AT STOPLIGHTS OR WHILE DRIVING. THIS IS A SAFETY ISSUE.

FIRST THERE WAS NO POWER TO THE CAR SO WE REPLACED THE BATTERY. THEN THE CAR WAS RUNNING AND SHUT OFF ONE DAY AND WOULD NOT RESTART. THE VEHICLE WAS STATIONARY WHEN IT WOULD NOT RESTART. WE HAD IT TOWED TO MERCEDES DEALER. THEY ARE STATING IT THE POWER ELECTRONICS MODULE. THERE ARE TWO RECALLS RELATED TO THIS PART BUT WHEN CHECKING THE VIN OURS IS NOT PART OF THEM. THAT IS IMPOSSIBLE. THE MERCEDES DEALER EVEN STATED THERE WERE ISSUES WITH THIS PART THAT'S WHY MERCEDES ONLY MADE THESE CARS FOR TWO YEARS. PLEASE SEE CAMPAIGN NO. 2012080004. *TR

THE CAR FIRST STARTED TO STOP INTERMITTENTLY WITHOUT ANY WARNING AT ALL AT THE TRAFFIC INTERSECTION, THEN I WAS ABLE TO START IT AGAIN AFTER SHUTTING EVERY THING DOWN. THEN A MONTH LATER, THE SAME THING HAPPENED AGAIN BUT THIS TIME I WAS NOT ABLE TO START THE CAR AGAIN. THIS COULD BE A VERY DANGEROUS SAFETY SITUATION IF THE ENGINE SHUTS DOWN WHILE I WAS DRIVING ON THE FREEWAY. MERCEDES ONLY PROVIDED TEMPORARY SOLUTION BY REPLACING THE CAR HYBRID INVERTER POWER ELECTRONIC CONTROL UNIT THROUGH A CAMPAIGN BULLETIN 2012080004. THIS BULLETIN APPLIES TO MERCEDES S400, 2010-2012 YEAR MODEL. HOWEVER, THE MAIN PROBLEM STILL REMAINS AND POSES A VERY SERIOUS SAFETY ISSUE FOR ALL THE DRIVER AND PASSENGERS. THIS IS NOT AN ISOLATE PROBLEM. ITS A VERY KNOWN PROBLEM FOR LOTS OF OWNERS FOR THOSE MODEL YEARS. MY CONTACT EMAIL ADDRESS IS "[XXX]" SHOULD YOU NEED TO CONTACT ME. PLEASE SEE THE ATTACHMENT FOR THE INVERTER. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *CC *TR

I HAVE A 2010 MERCEDES S400 THAT WAS PURCHASED NEW IN NYC AND I WAS PROMISED A 10YR/150K MILE WARRANTY BECAUSE OF A CARB ADOPTION NY AND 10 OTHER STATES WERE INVOLVED IN. MY VEHICLE HAS ONLY 37K MILES AND IS NEVER BEEN CRASHED OR PAINTED. I WENT TO MERCEDES OF MANHATTAN LOCATED ON 770 11TH AVE NYC, NY 10019. MY VEHICLE WAS DENIED THIS WARRANTY COVERAGE THE SERVICE MANAGER STATED BECAUSE IT'S AT HIS DISCRETION TO GRANT THIS OR NOT. I THEN PLEADED WITH HIM AND HE BEGAN TO INSULT ME SAYING MY VEHICLE IS FAR FROM PERFECT AND HE CAN'T GRANT AN ASSISTANCE. I MADE HIM AWARE OF MY WARRANTY INFORMATION I HAD AND HE SAID THERE IS NO NEED BECAUSE HE SEES EVERYTHING I HAVE ON HIS COMPUTER AND MERCEDES'BENZ DOESN'T MAKE MISTAKES. I THEN ASKED FOR A SPECIFIC REASON WHY I'M BEING DENIED AND HE THEN TOLD ME MY VEHICLE WASN'T UP TO DATE ON MAINTENANCE. I SHOWED HIM THE SERVICE RECORDS THAT SHOWED THE VEHICLE WAS UP TO DATE WITH MAINTENANCE AND HIS DEALER EVEN REPORTED IT ON CARFAX. HE THEN SAID HE WILL CALL ME BACK AND THEN REACHED THE CONCLUSION THAT THE 3 SCRATCHES ON MY REAR BUMPER WAS REASON ENOUGH TO DENY ME WARRANTY COVERAGE AND SENT ME A STATEMENT SHOWING IF ANY PART WAS DAMAGED DUE TO MISUSE OR DAMAGE THEN WARRANTY IS VOIDED. I THEN EXPLAINED TO HIM MY SCRATCHES ON THE BUMPER WOULDN'T HAVE ANY AFFECT OR INFLUENCE ON MY VEHICLES HYBRID BATTERY. HE SAID HE HAS THE TECHNICAL KNOWLEDGE AND HE CAN DENY ME FOR THAT. I NEED HELP PLZ. I HAVE BEEN TOLD BY THE MERCEDES PARTS DEPARTMENT THAT THE HYBRID BATTERY AND INSTALL COULD RANGE IN PRICE OF $32,000.00. MY QUESTION IS WHY DID MERCEDES GIVE CUSTOMERS A 10YR/150K MILE WARRANTY ON A VEHICLE THAT THEY ARE GOING TO NOT ACCEPT. MY VEHICLE IS 8 YEARS OLD BUT WAS ORIGINALLY PURCHASED FOR $100,000.00. I FEEL THIS IS UNFAIR AND THINK I NEED THE ASSISTANCE OF YOUR DEPARTMENT PLEASE.

VEHICLE BEGAN TO CUT COMPLETELY OFF WHEN STOPPED AT A RED LIGHT OR STOP SIGN. IT BEGAN TO TAKE LONGER AND LONGER TO RESTART WHEN TURNED OFF AND ON. EVENTUALLY THE VEHICLE WOULD NOT START AT ALL. WHEN TAKEN TO THE DEALER, I WAS INFORMED THAT THE POWER CONTROL MODULE WAS BAD AND THE COST TO REPLACE WAS UPWARD OF $11,000. AFTER SPEAKING TO MANY MANAGERS AND MY CAR SITTING AT THE DEALERSHIP FOR NEARLY 30 DAYS, I WAS CALLED AND INFORMED THAT THERE WAS A MANUFACTURER'S DEFECT FOUND IN THE POWER CONTROL MODULES WHICH WAS JUST EXTENDED TO COVER THE 2010 MODEL AND THAT THE MANUFACTURER WAS COVERING THE REPLACEMENT COSTS.
