STARTED WITH GASOLINE SMELL COMING FROM 03 CORVETTE. TOOK TO DEALER AND FOUND OUT THAT THE PROBLEM WAS ONE OF THE 2 GAS TANKS. UNABLE TO KNOW FOR SURE WITHOUT DROPPING THE WHOLE DRIVE TRAIN. THIS WAS DONE AND THE PLASTIC GAS TANK HAD DEVELOPED A LEAK. WAS INFORMED THAT THIS WAS A FLAW WITH SOME PRODUCTION CORVETTES. A VERY EXPENSIVE REPAIR BUT ONE THAT MUST BE DONE. CANNOT HAVE GAS VAPORS ESCAPING INTO THE AIR OR CONFINED IN A GARAGE. I HAVE ALREADY HAD 1 HOUSE FIRE, DON'T NEED ANOTHER ONE. IF GM KNEW ABOUT THIS PROBLEM, THEY SHOULD HAVE FIXED IT. BUYERS SHOULD NOT BE PUT IN HARMS WAY. *TR

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.
