ON JUNE 25, 2009 I POSTED THE FOLLOWING THREAD ON THE CORVETTE FORUM WEBSITE: I BEGAN PUMPING FUEL SLOWLY AND WHEN THE FUEL STARTED TO SPILL UNDER THE CAR I STOPPED AND I COULD NOT DETECT THE LEAK POINT. THE FUEL GAUGE READ OF A TANK. AFTER A SHORT TIME PERIOD THE FUEL QUITS LEAKING. I AM GUESSING THAT I HAVE A CRACK IN THE FILL TUBE. COULD SOMETHING ELSE BE GOING ON THAT I AM NOT AWARE OF BESIDES A FILL TUBE CRACK? WOW, OF ALL THE THINGS THAT COULD GO WRONG WITH A CAR, THIS IS A FIRST FOR ME. THE SECOND TANK CONNECTOR JOINT ON MY CAR IS SPLIT ALSO. I WENT TO THE DEALERSHIP TO CHECK IT OUT FOR MYSELF. THEY PRESSURED UP THE TANK WITH NITROGEN/SMOKE AND SMOKE WAS POURING OUT OF THE CONNECTION JOINT. BAD NEWS...........$2400 TO REPAIR WITH NEW PARTS AND 9 HRS. OF LABOR..........THE GREAT NEWS.. THANK GOD FOR MY GMPP, IT'S COVERED. MY ONLY COMPLAINT IS WHY GMPP WOULD NOT COVER TO HAVE THE PARTS OVERNIGHTED FOR $100?? THEY WILL PAY THE EXTRA THREE DAYS OF CAR RENTAL INSTEAD, FOR A TOTAL OF 5 DAYS. JUST DOESN'T SEEM TO MAKE GOOD BUSINESS SENSE, OH THAT'S RIGHT IT'S GM!! FURTHER MORE THE CAR ONLY HAS 34K MILES ON IT, NEVER HAD THIS ISSUE WITH ANY OTHER VEHICLE. *TR

IF YOU GO THE CORVETTE FORUM ONLINE YOU WILL SEE AN ONGOING DISCUSSION ON 2004 CORVETTES WITH FUEL TANK/CROSSOVER PIPES VENTING FUMES AND OR LEAKING. IT SEEMS LIMITED TO THE 2004 MODEL AND THE PROBLEM IS CRACKING FUEL TANKS OR BAD CROSSOVER PIPE SEALS THAT REQUIRE TANK REPLACEMENT TO REPAIR. THEY ARE CHARGING UPWARDS OF $2,400.00 TO REPAIR THIS! SINCE IT VENTS RAW FUEL AND OR FUMES INTO THE AIR I FEEL THIS SHOULD BE A RECALL FOR SAFETY REASONS BESIDES THE EMISSION VIOLATION! THIS IS A VERY COMMON PROBLEM ON THIS MODEL AND SHOULD BE LOOKED INTO BEFORE SOME ONES CAR EXPLODES! *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.
