THIS CAR HAS 23,000 MILES ON IT AND I AM THE ORIGINAL OWNER. IT HAS DEVELOPED SOME SORT OF FUEL LEAK ONE OF THE TWO FUEL TANKS OR THE CONNECTING TUBE WHILE SITTING PARKED THE GARAGE. GM HAS KNOW ABOUT THIS ISSUE FOR YEARS. THEY DID NOT WARN OWNERS OF THESE CARS OF THIS PROBLEM. NOW THAT I HAVE THIS ISSUE I HAVE DISCOVERED THE GM WOULD FIX THIS IF YOU DISCOVERED THIS PROBLEM IN TEN YEARS OR 100,000 MILES. THIS IS A MAJOR SAFETY ISSUE, THE CAR COULD EXPLODE IF A PERSON WALKS BY IT IN A PARKING LOT, IN AN ACCIDENT OR PARKED IN A PARKING STRUCTURE. THIS CAR IS NOW A TICKING BOMB DUE TO THE FAILURE OF GM TO NOTIFY OWNERS OR THIS POTENTIAL PROBLEM. ALL CORVETTES ARE NOT DAILY DRIVERS THAT IS WHY THE MILEAGE IS LOW. THERE ARE MANY CARS OUT THERE WITH THIS PROBLEM. IT IS IMPORTANT THAT GM SHOULD HAVE TO NOTIFY ALL OWNERS OF THIS VINTAGE OF CAR OF THIS ISSUE AND FIX THEM BEFORE PEOPLE GET HURT OR KILLED. NOT ONLY THE OWNERS OF THESE VEHICLES ARE AT RISK, SO IS THE GENERAL PUBLIC.

THE VEHICLE'S ELECTRONIC COLUMN LOCKING SYSTEM WAS HAVING INTERMITTENT SEVERE FAILURE. WHEN TRYING TO STEER THE CAR AFTER IGNITION AND MOVING DOWN THE ROAD THE WHEEL WOULD LOCK IN CERTAIN POSITIONS AND TO PREVENT A CRASH I WOULD HAVE TO STOP THE CAR AND HOPE THE LOCKING SYSTEM RELEASED. I FOUND THAT THIS ISSUE WAS COVERED BY #04006C PRODUCT SAFETY RECALL. WHEN I CONTACTED THE SERVICE DEPARTMENT AT NUCAR CHEVROLET; THEY INDICATED THAT THE RECALL WAS NOT STILL OPEN. THUS I WAS FORCED TO HAVE MY MECHANIC REPAIR THIS BEFORE A SERIOUS CRASH OCCURRED. I ALSO CALLED THE CHEVROLET PRODUCT RECALL LINE AND WAS TOLD THAT MY VEHICLE WAS NOT ONE OF THE AFFECTED VIN'S. THAT IS NOT THE CASE IF YOU REVIEW DOCUMENT ID#1761087 OR THE ATTACHED DOCUMENTATION I HAVE FOUND. ON 8/24/16 I PAID $215.46 PLUS MY TIME AND TALENT TO RESEARCH AND BRING THIS FORWARD. I BELIEVE GM NEEDS TO REIMBURSE ME FOR THIS ISSUE. PLEASE ADVISE HOW BEST TO PROCEED. THANK YOU *JS *JS

I TOOK IT TO A MECHANIC AND HE FOUND THAT THE TANK WAS LEAKING AS DESCRIBED IN GM SERVICE BULLETIN 10150 IN THE CONNECTION OF THE CROSSOVER BETWEEN THE TANKS. THE CAR HAS 56000 MILES ON IT. THIS IS A KNOWN DEFECT CAUSED BY THE USE OF IMPROPERLY MIXED ADHESIVE IN THE CONNECTOR. I CALLED THE NUMBER ON THE SERVICE BULLETIN AND GM SAID THEY WOULD NOT COVER THE FIX ON THIS KNOWN DEFECT BECAUSE THE ARBITRARY TIME THEY CREATED FOR REPAIR ON THIS HAD LAPSED.

THIS REQUEST INVOLVES A SAFETY BULLETIN [#0400C6], DATED 2/8/2006 RELATING TO THE ELECTRONIC COLUMN LOCK (ECL) FOR APPROXIMATELY 96% OF ALL 220,000+ C-5 GENERATION CORVETTES. 2004 WAS THE LAST YEAR OF PRODUCTION FOR THE C-5 GENERATION. TOTAL PRODUCTION IN 2004 IS ESTIMATED TO HAVE BEEN ABOUT 35,000: OUT OF THIS, 20,861 VEHICLES WERE COVERED BY THE ABOVE SERVICE BULLETIN, BUT AS MINE WAS ASSEMBLED AFTER VIN #45120862 UNTIL ASSEMBLY BEGAN FOR THE 2005 MODEL YEAR (C-6 GENERATION), MY VIN NUMBER WAS NOT INCLUDED ON PAGE 2 OF THE BULLETIN. PRIOR TO THE STEERING COLUMN ON MY CAR LOCKING ON 6/28/2016 I HAD NOT BEEN MADE AWARE THAT THIS PERILOUS CONDITION EXISTED. GM HAS INDICATED THAT IT WILL NOT PROVIDE ANY FUNDS TO OFFSET THE COST OF REPAIRING THIS FAULT BECAUSE IT WAS NOT INCLUDED ON ANY SERVICE BULLETIN. I BELIEVE THAT SERVICE BULLETIN #04006C WAS INTENDED FOR (OR SHOULD APPLY TO) THE ENTIRE C-5 PRODUCTION -- UNLESS THERE IS SOME REASONABLE EXPLANATION AS TO WHY MY VEHICLE HAS BEEN EXCLUDED (SUCH AS A DIFFERENT ECL CONFIGURATION WAS USED, ETC.) IN EITHER EVENT, I FEEL THE COMPANY SHOULD HONOR MY REQUEST FOR A FULL REIMBURSEMENT FOR FUNDS EXPENDED TO REPLACE THE FAULTY ECL. I HAVE WRITTEN A LETTER TO GM EXPLAINING THE FACTS SURROUNDING THIS REQUEST AND HAVE ATTACHED A COPY OF THAT LETTER FOR YOUR REVIEW.

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.
