DT*: THE CONTACT STATED WHILE MAKING A LEFT HAND TURN OUT OF A PARKING LOT AT 10 MPH, THE CONTACT LOST CONTROL OF THE VEHICLE. ALTHOUGH, THE STEERING WHEEL WAS MANUALLY ADJUSTED TO A STRAIGHT POSITION, IT CONTINUED TO MOVE TO THE RIGHT. THE VEHICLE THEN MADE A 270 DEGREE TURN TO THE LEFT AND HIT ANOTHER VEHICLE. THERE WAS NO DAMAGE OR POLICE REPORT TAKEN. THE VEHICLE WAS TOWED TO THE DEALERSHIP AND IT WAS DETERMINED THE STEERING LINKAGE FAILED AT THE KNUCKLE. A REPRESENTATIVE FROM THE MANUFACTURER READ THE BLACK BOX AND DETERMINED THE FAILURE WAS CAUSED BY THE IMPACT WITH THE OTHER VEHICLE. THERE IS A NHTSA RECALL, # 04V273000, REGARDING THE STEERING LINKAGES. THE VEHICLE HAS THE SAME PROBLEMS AS INDICATED IN THE RECALL; HOWEVER, IT IS NOT INCLUDED IN THE RECALL DUE TO THE VIN.

THIS IS STATED ON MY WORK ORDER AS "GENERIC RECALL".ON DATE BELOW I TOOK MY 04 CORVETTE TO THE DEALER FOR THIS WORK TO BE DONE. THE C-5 GENERATION HAS HAD CHRONIC PROBLEMS WITH THE STEERING WHEEL CONTINUING TO BE LOCKED AFTER INSERTING THE KEY. MANY MOTORISTS HAVE BEEN STRANDED IN BAD SITUATIONS WITH THIS FEATURE. THERE WAS A RECALL FOR THE AUTO. TRANS. THAT REMOVED THE PLATE FROM THE STEERING COLUMN SO THE STEERING WHEEL WOULD NO LONGER LOCK. THE WISDOM BEING THE VEHICLE WOULD BE IN PARK ANYWAY AND NOT EASY TO STEAL. WHAT THEY DID FOR US WITH STRAIGHT SHIFTS WAS REPROGRAM IT SO IF THE COLUMN LOCKED UP THE FUEL WOULD BE SHUT OFF. I WANT TO STATE AT THIS POINT MY CAR HAS NOT LOCKED UP 13,00 MILES BUT I DON'T LIKE THE ODDS BEING AGAINST ME. WE ARE DEALING WITH A RELAY AND A SLIDING PIN THAT HAS A HISTORY OVER TIME BEING PROBLEMATIC. THERE ARE PRODUCTS ON THE AFTER MARKET THAT SOME PEOPLE HAVE PURCHASED BUT I AM RELUCTANT TO BUY ONE MY SELF BECAUSE I'VE HEARD 1 THEY WON'T WORK IF YOU HAVE LET THE DEALER DO THE REPROGRAMMING 2 THEY COULD SCREW UP THE COMPUTER AT BIG$$$$ OR 3 IF THIS [XXX] THING EVER LOCKS UP WITH ME AT SPEED I WANT G M TOTALLY ON THE HOOK .GM WANTS TO SAY THIS IS NOT A SAFETY ISSUE BUT IF THERE IS SOMETHING WITH A CAR THAT OVER TIME HAS PROVED TO STRAND PEOPLE IN AREAS THAT ARE NOT SAFE TO BE STRANDED IN THE TIMES WE LIVE IN YOUR SAFETY IS INVOLVED. LET ME GIVE YOU AN EXAMPLE OF HOW I LOOK AT THIS. LETS SAY I KNOWINGLY HAVE A TIRE THAT HAS A SLOW LEAK AND I DON'T REPAIR IT THEN ONE DAY IT SUDDENLY LEAKS FAST AND I AM IN A DANGEROUS SITUATION THEN I'M REAL STUPID. WE ARE CAUGHT IN A BAD SITUATION THE FACTS ARE OUT THERE. MOST OWNERS WOULD PROBABLY BE GLAD TO SIGN A RELEASE NOT TO HOLD GM RESPONSIBLE IF OUR CAR IS STOLEN IF THEY REMOVE OUR LOCKING PLATES I KNOW I WOULD. REMEMBER THEY DID FOR THE AUTOMATICS ,THEY NEVER WOULD IF THIS WAS NOT A PROBLEM . MY BIGGEST CONCERN CONTINUES TO BE CAN THIS [XXX] THING LOCK UP AT SPEED. REMEMBER MURPHY'S LAW.

1) I RECEIVED A RECALL NOTICE FROM CHEVROLET RECALL INFORMATION PROCESSING CENTER ON MAY 13, 2004. THE RECALL IS # 04006 - ELECTRONIC COLUMN LOCK SYSTEM. THIS RECALL WAS STARTED ON FEB. 9, 2004 ACCORDING TO YOUR SITE. 2) I PURCHASE THE 2004 CHEVROLET CORVETTE COUP ON SEPTEMBER 9, 2004. I QUESTION CHEVROLET'S COMMITMENT TO SAFETY. ISSUEING A RECALL IN FEB. OF 2004 AND NOT BOTHERING TO REPAIR THE DEFECT WELL THE CAR WAS IN THEIR TOTAL CONTROL FOR 8 MONTHS, THEN SELLING ME THE CAR KNOWING FULL WELL THE DEFECT HAD NOT BE FIX, THEN WAITING ANOTHER 9 MONTHS TO NOTIFY ME. I CONTACED THE DEALER ON MAY 16, 2005, TO SEE IF THE CAR HAD THE RECALL DEFECT REPAIRED. IT HAD NOT. SO CHEVROLET HAS WAITED A TOTAL OF 17 MONTHS. NOT EXACTLY A CONSUMER ADVOCATE FOR SAFETY TO THE DRIVING PUBLIC. 3)ACCORDING TO THE DEALER, THIS WORK CAN ONLY BE DONE DURING THE WEEK, NOT A WEEKEND. SO NOW, I HAVE TO MISS A DAY OF WORK FOR A PROBLEM THAT SHOULD HAVE BEEN TAKEN CARE OF BEFORE I EVEN PURCHASED THE CAR. NOW I KNOW WHY CHEVROLET ALWAYS SENDS OUT A SATIFSFACTION QUESTIONAIRE 30 DAYS AFTER PURCHASE, BECAUSE THEY KNOW MOST OF THEIR VEHICLES SHOULD LAST THAT LONG. I'M SURE I WILL NOT GET ONE AFTER A YEAR HAS PASTED.

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.
