FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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.
NHTSA complaint #10839029 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
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.

FUEL SYSTEM, GASOLINE
AFTER I FILL THE CLS500 MB TANK WITH GAS, AND DRIVE INTO THE RESIDENTIAL GARAGE, AN HOUR LATER THE GARAGE IS FILLED WITH RAW GAS FUMES. IF I DON'T FILL THE TANK COMPLETELY, IT SEEMS TO BE OKAY. SOMETIMES THE FUMES ENTER THE HOME, AND MY GUESTS CAN SMELL THEM. IT'S QUITE EMBARRASSING WHEN YOU OWN A MB. THE GUESTS LEAVE RIGHT AWAY.

FUEL SYSTEM, GASOLINE
SEVERAL TIMES I HAVE NOTICED A STRONG ODOR OF GASOLINE INSIDE THE CAR AFTER FILLING UP AT THE GAS STATION. I HAVE NOTICED SEVERAL OTHER COMPLAINTS OF THE SAME NATURE. I NOTICED A RECALL # 2008-02001 SEEMS TO ADDRESS THIS MERCEDES-BENZ ISSUE BUT AM NOT SURE IT APPLIES TO THE CLS500. I THINK IT APPLIES TO THE CLS550 AND THE E-TYPE BUT IT SHOULD APPLY TO THE CLS500 SINCE THE UNDERPINNINGS OF THIS CAR IS THE E-TYPE. PLEASE ASSIST AS I WOULD LIKE TO HAVE THIS SAFETY ISSUE ADDRESSED BY MERCEDES-BENZ AND JUDGING FROM THE NUMBER OF COMPLAINTS FEEL THAT MERCEDES-BENZ SHOULD CORRECT THIS APPARENT DEFECT AT NO CHARGE.

NHTSA complaint #10557812 — an unverified report by a vehicle owner.
FUEL SYSTEM, GASOLINE
AFTER FILLING MY CAR, I STARTED SMELLING A GAS ODOR COMING FROM THE DRIVER SIDE BACK SEAT AREA WHEN I REACH HOME ABOUT 2 MILES AWAY FROM THE SERVICE STATION WHERE I FILLED UP. I FIGURE THE SMELL WOULD HAVE GO AWAY BUT EVERYTIME I DRIVE MY CAR I CAN BE ASSURED TO SMELL THAT GAS ODOR IN THE REAR DRIVER SIDE PASSENGER AREA WHICH NOW IS VERY ANNOYING FOR A CAR I PAID SO MUCH MONEY FOR. ....
NHTSA complaint #10556905 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
FROM A STOPPED POSITION THERE IS DELAY WHEN THE ACCELERATOR PEDAL IS PRESSED BEFORE THE ENGINE ACTUALLY BEGINS TO ACCELERATE. THE DELAY IS APPROXIMATELY 2 SECONDS AND PRESENTS SERIOUS DANGER WHEN ATTEMPTING TO PULL INTO APPROACHING TRAFFIC. I HAVE HAD A FEW CLOSE CALLS WHERE I WAS ALMOST HIT BY ANOTHER VEHICLE BECAUSE OF THE SIGNIFICANT HESITATION WITH THE ACCELERATION. I HAVE TAKEN THE VEHICLE TO THE DEALER A FEW TIMES, BUT THEY SAID THEY COULD NOT FIND ANY PROBLEM AND NO ERROR FAULTS HAD BEEN LOGGED IN THE VEHICLES COMPUTER. THE PROBLEM WAS INTERMITTENT INITIALLY BUT IS NOT CONSISTENTLY OCCURRING. I BELIEVE THIS IS A SERIOUS SAFETY ISSUE AND SUSPECT MY CASE IS NOT UNIQUE.

FUEL SENDING UNIT LEAKS AFTER FILLING UP GAS TANK. HOLDS THE RAW GAS IN TOP OF SENDING UNIT. CAUSES INSIDE OF CAR TO FILL UP WITH RAW GAS SMELL, GETS REALLY BAD ON HOT DAYS. SMELLS LIKE RAW GAS IN GARAGE. FUEL SENDING UNIT IS UNDER BACK SEAT BEHIND DRIVER, WHICH COULD BE VERY DANGEROUS.
