OUR 2004 CORVETTE WITH 27,630 MILES SUDDENLY BEGAN LEAKING GAS FUMES SO SEVERELY IN OUR GARAGE THAT WE WERE CONCERNED WE COULD HAVE AN EXPLOSION. WE ALSO COULD NOT SLEEP IN OUR BEDROOM AT THE OPPOSITE END OF OUR HOUSE DUE TO THE GAS FUMES. WE HAD NOT HIT ANYTHING OR HAD ANYTHING UNUSUAL HAPPEN TO OUR VEHICLE AND WE HAD A GM DEALER IN CHANDLER, AZ DETERMINE THERE WAS NO DAMAGE TO THE UNDERCARRIAGE OF THE CAR. THE DEALER DETERMINED THAT THE DRIVER'S SIDE GAS TANK HAD CRACKED NEAR THE TOP OF THE TANK. WE CONTACTED GM CUSTOMER SUPPORT AND AFTER WE WAITED A WEEK, WITH THE CAR AT THE DEALER'S LOT, GM DETERMINED THEY WOULD DO NOTHING! THEY REFUSED TO EITHER RECALL THE CORVETTE, ADMIT THERE IS A DEFECT IN THEIR GAS TANKS OR ASSIST FINANCIALLY IN REPLACING THE GAS TANK. WE THEN HAD THE GM DEALER REPLACE THE TANK AT A COST OF $1,991. THIS PRICE IS AFTER THE DEALER REDUCED THE COST BY GIVING US A 10% GOODWILL PRICE REDUCTION. DUE TO THE SERIOUS SAFETY DEFECT IN GM'S GAS TANK AND CROSSOVER SYSTEM, WE BELIEVE GM SHOULD IMMEDIATELY RECALL THE 2004 CORVETTES AS VARIOUS OTHER OWNERS HAVE REPORTED THAT THEIR DRIVER SIDE GAS TANK HAS CRACKED AND LEAKED FUEL AND GAS FUMES. THIS IS A SAFETY RECALL AND DEFINITE EPA ISSUE. THE VEHICLE AND OUR GARAGE CERTAINLY COULD HAVE EXPLODED AND THE VEHICLE WAS UNDRIVEABLE WHILE LEAKING FUMES. IT CERTAINLY COULD NOT HAVE PASSED AN EMISSIONS TEST. IS GM WAITING FOR AN EXPLOSION BEFORE THEY ACT? *TR

2004 CHEVROLET CORVETTE COUPE LEAKING DRIVER'S SIDE FUEL TANK. STARTED LEAKING ABOUT JULY 2009 AFTER DRIVING APPROXIMATELY 8300 ORIGINAL MILES BY ORIGINAL OWNER. LEAK BECAME WORSE OVER TIME AND RESULTING IN STRONG GASOLINE SMELL. HAD DEALER INSPECT THE CAR, HE DETERMINE THAT THE FUEL TANK LEAKS AT THE CROSSOVER CONNECTION OF THE LEFT TANK. I WAS CONCERNED ABOUT THE FIRE HAZARD HAVING THE CAR IN THE GARAGE WHERE A GAS FIRED WATERHEATER IS LOCATED. I HAD THE CAR REPAIRED BY THE CHEVY DEALER ON JANUARY 12, 2010, AT A COST OF $2083.-. THE REPAIR CONSISTED OF REPLACING THE LEFT FUEL TANK. I ALSO NOTICED THE CAR'S MILEAGE DROPPED FROM ABOUT 16MPG TO LESS THAN 12MPG IN CITY DRIVING. *TR
Official recalls
204V273000 · Steering:linkages
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.
