Steering

Jun 9, 2004 · NHTSA campaign 04V273000 · 41,928 vehicles

Problem: 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.

Original NHTSA wording

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.

Risk: 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.

Original NHTSA wording

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 & notes

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.

Gm recall no. 04043. Customers can also contact the national highway traffic safety administration's auto safety hotline at 1-888-DASH-2-DOT (1-888-327-4236).

Steering

Feb 9, 2004 · NHTSA campaign 04V060000 · 126,624 vehicles

Problem: 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 .

Original NHTSA wording

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 .

Risk: If this occurs, a crash could occur without warning.

Original NHTSA wording

IF THIS OCCURS, A CRASH COULD OCCUR WITHOUT WARNING.

Remedy & notes

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.

Gm recall no. 04006.customers can also contact the national highway traffic safety administration's auto safety hotline at 1-888-DASH-2-DOT (1-888-327-4236).

Fuel Tank Leak

PE10015 · opened May 12, 2010 · closed Sep 10, 2010

Summary

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 t…
