2006 MERCEDES BENZ CLS500 Fuel/propulsion System Problems

VERY STRONG GAS SMELL INSIDE THE CAR AND OUTSIDE THE CAR. GAS LEAKING ON THE FLOOR FROM GAS TANK AREA.

BOUGHT THE 2006 CLS 500 2 YEARS AGO, SINCE THAT SECOND DAY I HAVE ISSUES WITH SBC MODULE, I CALL MB DEALER THEY TOLD ME MY CAR WAS OUT OF WARRANTY, SINCE THE PRODUCTION DATE WAS 2004, OKAY AFTER THAT I TRY SEVERAL OTHER MECHANICS AND NOBODY HAVE THE STAR TOOL TO FIX UP, THE CAR IS NOT SAFE TO DRIVE AND I CONTINUE TAKE THE RISK COUPLE MONTHS UNTIL THE FUEL LINE STARTS LEAK ON THE PUMP, THIS COULD GENERATE A SPARK AND BURN MY CAR, I CALL AGAIN MB DEALER AND THEY TOLD ME IS PROBABLY UNSAFE TO START THE CAR. AFTER ALL THIS YEARS I PARKED THE CAR AND ALL MY SUSPENSION WAS BROKE AS WELL, CALL AGAIN THE MB DEALER THEY ESTIMATED $ 1800 TO REPLACE THE AIR SHOCKS, SO I BUY FROM ARNOTT THE SAME MB SELL AND I REPLACE ALL 4, SO THE CAR IS UP AGAIN, NEXT WEEK I DECIDE TO SELL THE VEHICLE AFTER DRIVING IN 3 YEARS 9,000 MILES ONLY, TRY TO MOVE THE CAR FROM THE GARAGE, GUESS WHAT, MY TRANSMISSION GO TO LIMP MODE BECAUSE THE BREAKS ARE NOT WORKING, SO FAR I DECIDE TO WRITE IN HERE TO COMPLAIN WHY A SUCH BEAUTIFUL CAR HAVE SO MANY ISSUES AND MB DOES NOT CARE FOR THE OLD MB. I ALMOST GET ON ACCIDENT WHEN MY BREAKS COMPLETE FROZEN TO THE END !!!

IN SEPTEMBER, 2015 TOOK MY VEHICLE TO HOUSTON GREENWAY (3900 SOUTHWEST FREEWAY; HOUSTON, TEXAS 77027) FOR AN INSPECTION OF THE FUEL TANK (STRONG FUEL ODORS WERE DETECTED). THE INSPECTION REVEALED THAT THE FUEL TANK REQUIRED REPLACEMENT. THE REPLACEMENT WORK WAS DONE AND I PAID FOR IT OUT OF POCKET. I RECENTLY RECEIVED A LETTER FROM MBUSA STATING THAT THE MBUSA HAD ELECTED TO EXTEND THE WARRANTY ON MY VEHICLE

I BEGAN SMELLING FUEL IN THE CABIN OF MY CAR AND CONTACTED THE MERCEDES BENZ DEALERSHIP IN MY AREA, WESTMINSTER, CO. THE WOMAN I SPOKE WITH TOLD ME THAT SHE WAS UNAWARE OF ANY ISSUES, BUT THAT SHE WOULD LOOK INTO IT AND GET BACK TO ME. I NEVER HEARD BACK. THE SMELL WAS GETTING WORSE AND AFTER 3 WEEKS, I COULD NOT DRIVE WITH MY WINDOWS CLOSED, GAGGED WHEN I GOT INTO THE CAR AND SMELLED LIKE FUEL UPON EXITING THE CAR. I CALLED MERCEDES BENZ AGAIN AND ASKED IF I COULD BRING THE CAR IN. I WAS TOLD I COULD AND THAT THERE WAS A WARRANTY EXTENSION FOR FAULTY FUEL TANKS. THE FUEL TANK WAS ALLEGEDLY REPAIRED, BUT UPON RETURNING THE CAR TO ME, THE CAR STILL SMELLED LIKE FUEL. I THOUGHT THE SMELL MIGHT DISSIPATE OVER A FEW DAYS, BUT IT DID NOT, SEEMED TO GET WORSE AGAIN, SO I TOOK THE CAR BACK IN. I WAS TOLD BY THE SERVICE REP THAT THE FUEL HAD LEAKED INTO THE UNDERLAYMENT OF THE CAR AND WAS DETERIORATING THE FLOOR BOARDS. I WAS ALSO TOLD TO "NOT SMOKE IN THE CAR" BY THE SERVICE REP. MERCEDES BENZ IS NOW REFUSING TO REPAIR THIS DAMAGE CAUSED BY THE FAULTY PART. THEY FEEL THAT THE CAR IS "SAFE" EVEN THOUGH I WAS TOLD NOT TO SMOKE IN IT. I DON'T SMOKE, BUT IF THERE IS AN ELECTRICAL SPARK OR I GET IN AN ACCIDENT, I DON'T WANT THE CAR TO BLOW UP.

STRONG SMELL OF GASOLINE IN INTERIOR OF CAR ALONG WITH SMELL IN GARAGE AFTER OVERNIGHT PARKING. CHECKED ENGINE FOR LEAKS AS WELL AS GENERAL TANK AREA. NEGATIVE. I THINK THAT THE FUEL SENDING UNIT (UNDER REAR SEAT MAY BE LOOSE OR DEFECTIVE. CAN'T OVER EMPHASIZE THE STRONG GAS SMELL, WHILE STATIONARY--SEEMS TO DISSIPATE ON MOVEMENT.

FUEL PUMP LEAKS AND VAPOR SMELL IS VERY PREVALENT. FUEL TANK ASSEMBLY HAS BEEN ORDERED, BUT APPARENTLY MERCEDES IS VERY SLOW ON SHIPPING THE PARTS BECAUSE THERE ARE SO MANY CARS WITH THIS SAME PROBLEM. BESIDES THE SMELL, I THINK THIS COULD BE DANGEROUS. I HAVE ALWAYS BEEN TOLD THAT WHERE THERE ARE FUMES AN EXPLOSION IS POSSIBLE.I HAVE BEEN TOLD THAT PARTS HAVE TO COME FROM GERMANY SINCE NO ONE IN THE STATES HAS THEM. MERCEDES SHOULD BE ASHAMED AND HELD TO A HIGHER STANDARD. *TR

WHEN FUEL TANK IS FILLED COMPLETELY THERE IS AN EXTREMELY STRONG ODOR OF GASOLINE INSIDE AND OUTSIDE CAR. FUEL PUMP HAS BEEN REPLACED AND THE FUEL TANK SEALS HAVE BEEN REPLACED MULTIPLE TIMES WITH NO IMPROVEMENT. GAS CAP WARNING LIGHT NOW COMES ON INTERMITTENTLY AND CHECK ENGINE LIGHT REMAINS ON. HAVE BEEN ADVISED TO REPLACE FUEL TANK NOW. *TR

JUST LIKE THE OTHER MERCEDES VEHICLES, THE FUEL PUMPS ARE UNDER THE BACK SEAT. MY DAUGHTER RIDES IN THE BACK. ONE MORNING I WAKE UP AND MY CAR SMELLED AS IF SOMEONE POURED GASOLINE ALL THROUGHOUT THE AUTOMOBILE. I LET THE WINDOWS DOWN AND TOOK MY CAR TO AMERICAN AUTO TECH WHERE I SPENT OVER 700.00. IT TOOK OVER 2MONTHS TO GET THE SMELL OUT OF THE CAR AND I HAD TO REPLACE THE COVER AND LINING THAT SEPARATES THE BACK SEAT CUSHION PORTION FROM THE ENTRANCE OF THE FUEL PUMPS THAT SIT UNDER BOTH BACK SEATS OF THIS CAR. THIS IS NOT ONLY AN ISSUE WITH THE E CLASS BUT MOST MERCEDES MADE THROUGH OUT THAT YEAR. I HAVE A RECEIPT IN WHICH I HAVE PAID AND FEEL THAT MERCEDES NEED TO COMPENSATE ME AND OTHERS FOR THIS DEFECTIVE PART OR FUEL LEAKAGE. IT EVEN LEAKS FROM UNDER THE CAR. THIS IS VERY DANGEROUS TO MY FAMILY AND OTHERS AROUND. *TR

THROUGH SOME CHECKING, GASOLINE SEEMS TO BE RUNNING OUT OF THE TOP OF THE GAS TANK WHEN IT IS FULL. IT IS NOT COMING FROM THE FUEL PUMP MODULE SEAL. THIS IS BOTH DANGEROUS AND A POLLUTION AND HEALTH RISK. I JUST BOUGHT THE CAR, SO I DON'T KNOW HOW LONG THE PROBLEM HAS EXISTED. HE TOLD ME THAT IS THE PROBLEM WITH THE FUEL SENDING UNIT IS LEAKING UNDERNEATH OF THE SEATS. HE ALSO TOLD ME THAT HE JUST FIXED TWO CARS WITH THE SAME PROBLEM. THERE IS ALSO A RECALL CAMPAIGN NUMBER (2008-020001) OUT HERE STATING THE SAME ISSUE, BUT MB AT ARLINGTON TOLD ME THAT IT WILL COST ME TO GET IT FIX BETWEEN $400 TO $730 AND MY CAR IS NOT COVER UNDER THIS RECALL. HE PULLED UP THE VIN OF MY CAR AND TOLD ME SORRY THAT YOUR CAR DOESN'T HAVE ANY RECORDS FOR RECALL. SO, I TOOK MY CAR BACK AND ASKED HIM TO PROVIDED ME THE COST ESTIMATE, I CALLED THE EXTENDED WARRANTY AND IT IS NOT COVER UNDER MY BASIC PLANS. SO, I DROVE THE CAR HOME, SMELLING LIKE THE I HAVE BEING SHOWERED BY THE SMELL OF LEAKING FUEL. I ALSO, GAVE A CALL TO MBUSA AND FILE MY COMPLAIN, AND SOMEONE CHECKED MY VIN AND TOLD ME THAT MY CAR DOESN'T COVER UNDER THE RECALL, BUT SHE WILL PUT THE FILE TOGETHER AND WILL BRING IT UP TO THE UPPER MANAGER TO REVIEW THE CASE AND TOLD ME THAT SOMEONE WILL GIVE ME A CALL BACK ON MONDAY SINCE THEY ARE CLOSING ON THE WEEKEND. THE WARRANTY DOESN'T COVER THE SENDING UNITS. BY NOW I HAVE ALL MY RESEARCH HANDY (AND HAVE ALREADY PRICED OUT THE REPLACEMENT OF BOTH UNITS - $2,000) AND SAID "WELL THERE'S BEEN A RECALL FOR THIS EXACT ISSUE ON THIS EXACT CAR, IT'S A MAJOR SAFETY CONCERN THAT'S WHY I WANT TO SHARE MY PROBLEM WITH OTHER PEOPLE ON THE MATTER." I PROVIDED THE RECALL CAMPAIGN NUMBER (2008-020001) AND ADVISE HER PLEASE LET THEM KNOW OF THE PLEDGED TO LOOK INTO IT. WISH ME LUCK :(. *TR

I FILLED MY GAS TANK AND DROVE HOME, PARKED IN THE GARAGE OVERNIGHT. THE NEXT MORNING I ENTERED THE GARAGE AND WAS OVERWHELMED BY THE SMELL OF RAW GAS. THE GARAGE WAS CLOSED AND IT CONTAINS A HOT WATER HEATER WHICH COULD HAVE EASILY LIT THE GAS FUMES AND STARTED A FIRE OR EXPLOSION. MY 2 KIDS' BEDROOMS ARE ABOVE THE GARAGE. THROUGH SOME CHECKING, GASOLINE SEEMS TO BE RUNNING OUT OF THE TOP OF THE GAS TANK WHEN IT IS FULL. IT IS NOT COMING FROM THE FUEL PUMP MODULE SEAL. THIS IS BOTH DANGEROUS AND A POLLUTION AND HEALTH RISK. I JUST BOUGHT THE CAR, SO I DON'T KNOW HOW LONG THE PROBLEM HAS EXISTED. *TR
