ON THURSDAY, AUG. 12, 2010, I STOPPED BY AT A GAS STATION TO FILL UP MY GAS TANK ON MY 2004 CHEVROLET CORVETTE COUPE. AFTER TRAVELING APPROXIMATELY 4 MILES FROM THE GAS STATION, I NOTICED A GAS LEAK UNDERNEATH COMING FROM THE LEFT DRIVER'S SIDE NEAR THE GAS TANK AREA. AFTER DISCOVERING THE PROBLEM, I IMMEDIATELY DROVE THE CAR TO A CHEVROLET SERVICE DEALERSHIP. AFTER HAVING A CERTIFIED GM MECHANIC LOOKING AT THE PROBLEM, THEY DISCOVERED IS WAS A DEFECTIVE TANK CONNECTOR (CROSSOVER PIPE) THAT CRACKS UNDER STRESS. WHAT NEEDED TO BE REPLACED WAS THE O-RING SEALS AND CONNECTOR PIPE ($250). THE LABOR CHARGE FOR REPLACING THESE PARTS ON A 2004 CORVETTE WAS $845. IT IS ALSO MY UNDERSTANDING THAT IN 2003 TO 2004, GM HAD THESE CROSSOVER PIPES CHANGED FROM A RUBBER TO A STEEL MATERIAL BECAUSE OF GAS AND HIGHWAY EMISSIONS. I WOULD LIKE TO MAKE STATEMENT TO EVERY OWNER OF 2004 CORVETTE, THAT THERE IS IN FACT A DEFECTIVE CROSSOVER PIPE THAT WILL LEAK GASOLINE AND WILL EVENTUALLY CAUSE A FIRE HAZARD IF IT IS NOT REPLACED. *TR

I OWN A 2004 CORVETTE AND AM VERY CONCERNED ABOUT THE MANY REPORTS OF A MFG. DEFECT IN THE FUEL TANK CROSSOVER QUICK CONNECT, CAUSING A FUEL LEAK AND POTENTIAL FIRE, LOSS OF LIFE. "THE CROSSOVER QUICK CONNECT IS AN INJECTION MOLDED COMPONENT MOLDED AT VIKING PLASTICS USING A MATERIAL PROVIDED BY POLYONE CORP. DURING THE COMPOUNDING PROCESS AT POLYONE CORP. ON SEPTEMBER 30, 2003, POLYONE CORP. MIS-PROCESSED A 3,000 POUND BATCH OF THE CROSSOVER QUICK CONNECT MATERIAL WHICH SIGNIFICANTLY DEGRADED THE MOLECULAR WEIGHT OF THE GLASS FILLED OLEFIN MATERIAL AND ULTIMATELY THE FRACTURE TOUGHNESS OF THE QUICK CONNECT." "POLYONE ALSO KNOWINGLY REPORTED INCORRECT PELLET SIZE ON THE MATERIAL CERTS." SUSPECT THAT COMPONENTS THAT SHOULD HAVE BEEN SCRAPPED, WERE RE-INTRODUCED INTO PRODUCTION ON AT LEAST TWO OTHER OCCASIONS." THIS IS FROM A GM LETTER FROM TERRY M. STONE TO DAVE REEK ON 10/08//2004 SUBJECT: FUEL LEAKS-ROOT CAUSE. ALSO IN ANOTHER LETTER PE 10-015 N100150 RESPONSE DATED JUNE 30, 2010 ON PAGE 13: "FUEL TANKS WITH SUSPECT QUICK CONNECTORS USING MATERIAL COMPOUNDED ON SEPTEMBER 30, 2003 AND JANUARY 7, 2004 WERE INSTALLED IN VEHICLES PRODUCED FROM APPROXIMATELY OCTOBER 22, 2003 THROUGH MARCH 19, 2004." "GM DOES NOT BELIEVE THAT THE ALLEGED DEFECT REPRESENTS AN UNREASONABLE RISK TO VEHICLE SAFETY." I STRONGLY DISAGREE WITH GM'S STATEMENT. ANY FUEL LEAK CAUSED BY A MFG. DEFECT POSES A MAJOR RISK TO VEHICLE SAFETY DUE TO THE POTENTIAL OF FIRE FROM LEAKING GAS. ONCE AGAIN, THERE HAVE BEEN MANY REPORTS OF THIS DEFECT AND I AM VERY CONCERNED THAT MY CAR COULD HAVE A DEFECTIVE GAS TANK WHICH SHOULD BE REPLACED BY GM IF A LEAK OCCURS. I ENCOURAGE THE NHTSA TO ISSUE AN IMMEDIATE RECALL OF THESE DEFECTIVE TANKS ON 2003/2004 CORVETTES/CADILLAC XLR VEHICLES BEFORE THERE IS A FIRE OR LOSS OF LIFE. UPDATED IVOQ 11/02/10 *TR

I BOUGHT THE 2004 VETTE COUPE ON 5-29-10 FROM A LOCAL DEALER. THE CAR SEEMED CLEAN. I HAVE PUT A LITTLE OVER 1,000 EASY MILES ON THE CAR IN 9 WEEKS. I STARTED TO NOTICE A SMELL COMING FROM THE CAR WHEN I WOULD GET HOME AND BEGAN TO RUN FANS TO GET IT OUT OF THE GARAGE. I FINALLY TOOK IT TO A LOCAL CADILLAC DEALER SINCE I WAS NOT SURE I COULD TRUST THE DEALER THAT SOLD ME THIS CAR WITH A PROBLEM AND THEY FOUND A GAS LEAK AT THE JOINT WHERE THE TUBE THAT CONNECTS THE TWO TANKS COMES OUT OF THE RIGHT TANK. IT ONLY DRIPS WHEN IT HAS BEEN DRIVEN BUT IS NOW QUITE BAD. I HAVE NOT DARED DRIVE IT FOR THE LAST WEEK. IT HAS NOT BEEN WORKED ON BECAUSE I WAS ADVISED TO CALL GM TO SEE IF THEY COULD HELP OUT ON THIS COSTLY REPAIR. I HAVE NOT HEARD BACK FROM THEM AS YET. THE GM REP DID ASK ME TO TAKE IT BACK TO THE ORIGINAL SELLER FOR ANOTHER INSPECTION EVEN THOUGH ANOTHER DIVISION OF THEIR COMPANY HAS ALREADY IDENTIFIED THE PROBLEM AND EVEN SHOWED ME THE LEAKING LOCATION. THIS IS A VERY DANGEROUS SITUATION AS GAS NOW DRIPS ON THE GROUND IN FRONT OF THE RIGHT REAR TIRE. ANY THING YOU CAN DO TO SEE TO IT THAT THIS SITUATION IS CORRECTED QUICKLY MAY SAVE SOMEONE'S LIFE. I CONSIDER MYSELF FORTUNATE TO HAVE FOUND OUT WHAT WAS WRONG WITHOUT BEING HURT OR KILLED. *TR

TL* THE CONTACT OWNS A 2004 CHEVROLET CORVETTE. THE CONTACT STATED THE VEHICLE WAS PARKED IN A RESIDENTIAL GARAGE WHEN THE CONTACT NOTICED THERE WAS A STRONG, OVERPOWERING GASOLINE ODOR FROM THE VEHICLE. THE CONTACT HAD RECENTLY REFUELED THE VEHICLE AND FOUND A LARGE, ABNORMAL PUDDLE OF GASOLINE UNDER THE VEHICLE. THE DEALER ADVISED THAT THE DRIVE SIDE FUEL TANK HAD FRACTURED AND WAS LEAKING. THE DEALER REPLACED THE FUEL TANK. THE FAILURE DID NOT RECUR. THE FAILURE MILEAGE WAS 43,617 AND THE CURRENT MILEAGE WAS 43,968.
EACH TIME I FILL THE GAS TANK THERE IS A STRONG GAS ODOR UNTIL THE FUEL LEVEL IS BELOW HALF A TANK AND THEN THE ODOR OF GAS IS NONEXISTENT. THE DRIVERS SIDE OF THE CAR HAS A STRONGER ODOR OF GAS WHEN PRESENT. *TR

Jun 9, 2004
ON CERTAIN PASSENGER VEHICLES INVOLVED IN THIS CAMPAIGN, THE LOWER CONTROL ARM BALL STUD NUT/WASHER ASSEMBLIES WITH WASHERS WERE MADE OF THE WRONG MATERIAL. THE WASHERS MAY FRACTURE AND BECOME LOOSE OR FALL AWAY FROM THE VEHICLE, REDUCING CLAMP LOAD. SEPARATION OF THE CONTROL ARM BALL STUD AND STEERING KNUCKLE, DUE TO DISENGAGEMENT OF THE TAPERED ATTACHMENT AND RETAINING NUT, IS POSSIBLE.
Consequence & remedy
Consequence: IF THE CONTROL ARM SEPARATES FROM THE KNUCKLE, THE AFFECTED CORNER OF THE VEHICLE WILL DROP AND THE CONTROL ARM WOULD BE FORCED DOWNWARD, CONTACTING THE WHEEL. THE AFFECTED WHEEL COULD TILT OUTWARD AND CREATE A DRAGGING ACTION THAT WOULD TEND TO SLOW THE VEHICLE AND CREATE A TENDENCY FOR THE VEHICLE TO TURN IN THE DIRECTION OF THE AFFECTED WHEEL. IN EXTREME SITUATIONS, THE AFFECTED WHEEL ASSEMBLY COULD SEPARATE FROM THE VEHICLE. SEPARATION OF THE WHEEL ASSEMBLY WOULD ALSO SEVER THAT WHEEL;S HYDRAULIC BRAKE HOSE AND RESULT IN DIMINISHED BRAKING PERFORMANCE OF THE VEHICLE, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSPECT THE BALL STUD JOINTS AND MEASURE THE TORQUE OF THE NUT FOR ALL FRONT LOWER CONTROL ARMS IN ALL MODELS AFFECTED AS WELL AS THE REAR LOWER CONTROL ARMS ON THE XLR AND CORVETTE. IF THE TORQUE IS NOT AT SPECIFICATION, THE DEALERS WILL REPLACE THE BALL STUD, THE KNUCKLE, AND THE NUT. IF THE TORQUE IS AT SPECIFICATION, THE DEALERS WILL REPLACE THE NUT/WASHER ASSEMBLY ONLY. THE RECALL WILL BEGIN ON AUGUST 25, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339 OR CHEVROLET AT 1-800-630-2438.
04V060000 · Steering:column LOCKING:ANTI-THEFT Device
Feb 9, 2004
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH ELECTRONIC COLUMN LOCK SYSTEMS (ECL), WHEN THE IGNITION SWITCH IS TURNED TO "LOCK," THE ECL SYSTEM PREVENTS TURNING OF THE STEERING SYSTEM. WHEN THE VEHICLE IS STARTED, THE ECL UNLOCKS THE STEERING SYSTEM. THE VEHICLE IS DESIGNED SO THAT IF THE COLUMN FAILS TO UNLOCK WHEN THE VEHICLE IS STARTED AND THE CUSTOMER TRIES TO DRIVE, THE FUEL SUPPLY WILL BE SHUT OFF SO THAT THE VEHICLE CANNOT MOVE WHEN THE VEHICLE CANNOT BE STEERED. IF VOLTAGE AT THE POWERTRAIN CONTROL MODULE IS LOW OR INTERRUPTED, HOWEVER, THE FUEL SHUT OFF MAY NOT OCCUR AND THE VEHICLE CAN BE ACCELERATED WHILE THE STEERING SYSTEM IS LOCKED. ALSO WHEN THE CONTROL SYSTEM SHOWS THAT THE ECL IS UNLOCKED AND THE VEHICLE IS BEING DRIVEN, THE LOCK PIN LOCATION CAN VARY. DEPENDING ON THE LOCATION OF THE LOCK PLATE RELATIVE TO THE SWITCH TRANSITION POINT, THERE COULD THEN BE CONTACT BETWEEN THE LOCK PLATE AND PIN CAUSING THE STEERING TO LOCK WHILE DRIVING .
Consequence & remedy
Consequence: IF THIS OCCURS, A CRASH COULD OCCUR WITHOUT WARNING.
Remedy: ON VEHICLES EQUIPPED WITH AN AUTOMATIC TRANSMISSION, THE DEALER WILL DISABLE THE STEERING COLUMN LOCK BY REMOVING THE COLUMN LOCK PLATE. WHEN THE IGNITION KEY IS REMOVED, THE TRANSMISSION SHIFTER WILL LOCK BUT THE STEERING COLUMN WILL NOT LOCK. ON VEHICLES EQUIPPED WITH A MANUAL TRANSMISSION, THE DEALER WILL REPROGRAM THE POWERTRAIN CONTROL MODULE, PERFORM A DIMENSIONAL CHECK OF THE COLUMN LOCK AND, IF NECESSARY, REPLACE THE LOCK PLATE. THE STEERING COLUMN ON THESE VEHICLES WILL CONTINUE TO LOCK WHEN THE KEY IS REMOVED. OWNER NOTIFICATION TO OWNERS OF 1997 VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS BEGAN ON APRIL 26, 2004. OWNERS OF 1998 THROUGH 2004 VEHICLES (EXCEPT 1997-1998 MANUAL TRANSMISSION VEHICLES) WILL BE NOTIFIED BEGINNING ON AUGUST 2, 2004. THE REMAINING OWNERS (1997-1998 MANUAL TRANSMISSION VEHICLES) WILL BE NOTIFIED LATER IN 2004, WHEN PARTS ARE AVAILABLE. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438.

In its June 30, 2010 response to ODI's Information Request letter, General Motors (GM) identified the leak source as cracks in either the fuel tank cross-over tube quick connector (connector) and/or the hot-plate weld joint of the connector to the tank.The root causes are attributed to errors in connector material processing, variations in the welding process, and high stresses placed on the driver's side connector during vehicle use.GM also identified the scope of the subject vehicles involved to be those produced from approximately October 22, 2003 through March 19, 2004.GM does not believe the cracks represent an unreasonable risk to motor vehicle safety based on factors that include; low rate of fuel leaking to the ground, detectable fuel odor, the cracks are at the top of the tank, leaks are detectable during refueling, small quantities of fuel that leaks out, and no associated property damage or personal injury claims.On August 13, 2010, GM issued a Special Coverage Adjustment to remedy fuel tank quick connector leaks and extend the warranty for this issue to 10 years or 100,000 miles in certain 2004 Chevrolet Corvette and Cadillac XLR vehicles.Vehicle owners will be notified by mail of the adjustment and will also be entitled to reimbursement for previously paid repairs covered under the adjustment.(See file for, SERVICE BULLETIN 10150: SPECIAL COVERAGE ADJUSTMENT-FUEL TANK QUICK CONNECTOR LEAK).The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency reserves the right to take further action if warranted by the circumstances.
