2008 MERCEDES-BENZ CLS550 Complaints

PARKING BRAKE INOPERATIVE AND A YELLOW PARK TRIANGLE WARNING AT LEFT CORNER OF THE DASHBOARD DISPLAY.

I WAS DRIVING G THROUGH A PARKING LOT WHEN THE SERPENTINE BELT BROKE. NATURALLY, THE CAR BECAME DIFFICULT TO STEER BUT MANAGEABLE. AS I ATTEMPTED TO TURN INTO A PARKING SPOT I HEARD A 'POP' UNDER THE HOOD. WHEN THIS OCCURRED, THE WHEEL WENT INTO A FREE SPIN. THERE WAS NO INPUT FROM THE STEERING WHEELS TO THE RACK AND PINION. UPON INVESTIGATION I FOUND THE LOWER STEERING SHAFT BROKEN ABOUT 2 INCHES ABOVE THE RACK SPLINE. THE STEERING SHAFT WAS BROKEN IN TWO. THE INCREASED FORCE REQUIRED TO TURN THE WHEEL WAS TOO MUCH FOR THE SHAFT TO HANDLE. *TR

LEAKING FUEL AROUND THE FUEL SENDING UNIT UNDER REAR SEAT BEHIND DRIVER, FILLING THE PASSENGER COMPARTMENT WITH GASOLINE FUMES, AFTER FILLING THE CAR UP WITH GASOLINE.

I PULLED INTO A SERVICE STATION TO FILL MY TANK. AFTER ADDING FUEL TO CAPACITY I BEGAN TO SMELL FUEL IN THE PASSENGER COMPARTMENT. I ATTRIBUTED THE SMELL TO POSSIBLY SPILLING FUEL ON MYSELF. I DROVE THE VEHICLE TO WORK AND THEN HOME. THE NEXT MORNING I CONTINUED TO SMELL FUEL IN THE PASSENGER COMPARTMENT. I TOOK THE VEHICLE TO THE DEALER FOR DIAGNOSIS AND WAS TOLD THAT THERE WAS A LEAK IN THE TANK THAT WAS SPLASHING / VENTING INTO THE PASSENGER COMPARTMENT. THE SERVICE TECHNICIAN SHARED THAT THIS WAS A COMMON PROBLEM WITH THE CLS. *TR

WHILE APPROACHING INTERSTATE ON RAMP BEGAN TO HEAR A LOUD WHISTLING SOUND COMING FROM THE FRONT LEFT WHEEL WELL. I PULLED OVER AND FOUND THE LEFT FRONT SUSPENSION BEGINNING TO SINK. THE STRUT LOWER TO A POINT WHERE THE BODY OF THE CAR WAS ONLY 2-3 INCHES ABOVE THE TIRE. WHEN I CHECKED THE DASHBOARD INDICATORS I HAD AN ERROR LIGHT INDICATING THAT THE VEHICLE WAS TOO LOW TO DRIVE. *TR

ON MARCH 10, 2012 MY WIFE STARTED THE AFOREMENTIONED VEHICLE AND IMMEDIATELY BEGAN TO SMELL GASOLINE FUMES IN THE PASSENGER COMPARTMENT. AS SHE EXITED THE PARKING GARAGE, THE TOXIC FUEL SMELL BECAME UNBEARABLE AND SHE IMMEDIATELY TURNED- AROUND, RE-ENTERED THE GARAGE, QUICKLY SHUT OFF THE CAR AND EXITED THE VEHICLE FOR FEAR OF FAINTING AND / OR AN EXPLOSION. THE MB REP EXPLAINED TO US THAT THERE WAS A FAILURE IN THE FUEL DELIVERY SYSTEM; WHICH IS ACCESSIBLE UNDER THE BACKSEAT OF THE PASSENGER COMPARTMENT; AND THE LEAKAGE CAUSED FUEL TO BE PUMPED INTO THE PASSENGER CABIN AND ACCUMULATE UNDER THE REAR SEAT; THEREBY SATURATING THE INSULATION, CARPET AND REAR SEAT CUSHIONS. THE MECHANICS REPLACED THE FUEL SYSTEM; AND REITERATED THAT THE GASOLINE LEAKED UP INTO THE PASSENGER COMPARTMENT (FROM THE FAULTY FUEL DELIVERY SYSTEM LOCATED UNDER THE BACK SEAT OF THE VEHICLE), SATURATED THE CARPET, THE FLOOR INSULATION AS WELL AS THE ACTUAL SEAT CUSHIONS. IN OUR OPINION, A CRITICAL VEHICLE DESIGN SAFETY FEATURE (IN THE EVENT OF A COLLISION) IS NOT TO PERMIT FUEL TO BE PUMPED INTO THE PASSENGER COMPARTMENT; WHICH WOULD INCREASE THE LIKELIHOOD OF AN INTERIOR EXPLOSION, AND AT A MINIMUM IMPAIR THE ABILITY OF THE OCCUPANTS TO SAFELY EXIT THE VEHICLE, BEFORE SUCCUMBING TO TOXIC FUMES. THE DEALER SERVICE REP?S RESPONSE WAS: ?MB HAS DETERMINED THAT THE SAFEST PLACE TO LOCATE THE FUEL DELIVERY SYSTEM IS UNDER THE BACK SEAT OF THE VEHICLE?. I IMPLIED THAT HIS RESPONSE WAS NOT ACCEPTABLE. INTERESTINGLY, THE MB DEALER SERVICE REP CALLED US AND SAID MB INC. WOULD COVER THE COST OF THE REPAIR. HOWEVER, REPAIRING THE PASSENGER COMPARTMENT DAMAGE AND DEFECTIVE FUEL SYSTEM DOES NOT ALLEVIATE THE CAUSE OF THIS DANGEROUS SITUATION. *TR

TL* THE CONTACT OWNS A 2008 MERCEDES-BENZ 550 CLS. THE CONTACT STATED THAT FUEL COULD BE SMELLED INSIDE THE VEHICLE WHILE DRIVING AND WHILE THE VEHICLE WAS SITTING IN PARK. THE CONTACT TOOK THE VEHICLE TO A DEALER FOR A DIAGNOSTIC TEST. THE TEST RESULTS SHOWED THAT A VENT INSIDE THE FUEL TANK WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE CONTACT DID NOT HAVE THE VENT REPLACED. THE CONTACT CALLED THE MANUFACTURER. THE MANUFACTURER ADVISED THAT THE FAILURE HAD BECOME A COMMON PROBLEM FOR THE PARTICULAR YEAR, MAKE AND MODEL BUT A RECALL HAD NOT BEEN ISSUED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 30,000.
