In temperatures between -22 and -40 degrees F, and if one of the accelerator pedal return springs breaks, the engine may not return to idle within three seconds as required. If this were to happen, more braking effort may be needed to stop the vehicle. Dealers will replace the accelerator pedal assembly. The recall began March 8, 2005. The GM recall number is 05018.
Under certain conditions, the shift lever position indicator located in the instrument cluster may not illuminate. If the indicator does not illuminate, the driver may not know which gear the vehicle is in. This could result in the vehicle moving in an unintended direction, increasing the risk of a crash. Dealers will reprogram the instrument panel cluster to correct this concern. This recall is expected to begin on February 14, 2005. The General Motors recall number is 05023.
On certain vehicles, the rear brake lines may be close, or come into contact with the exhaust manifold. This could heat the lines and boil the brake fluid; the lines could also wear from contact. If the brake fluid boils, or leaks, effectiveness of the rear brakes would be reduced and a crash could occur.
Dealers will inspect the left engine exhaust manifold clip for alignment and placement on the body mounted stud. If it's correct, they will reposition the clip on the brake lines and reinstall the clip on the stud. Dealers will ensure that both rear brake lines have the proper clearance to the left exhaust pipe and the machining tab on the rear differential housing will be removed. The brake lines in the affected areas will be inspected for damage and will be replaced if there are signs of wear-through on the nylon overcoating. The recall began January 18, 2005. The GM recall number is 04086.
The washer for the control arm ball stud may have been made of the wrong material, and may fracture and fall out, or become loose. The control arm may separate from the steering knuckle due to disengagement of the tapered stud, causing the vehicle to drop at that corner. In extreme situations, the wheel may separate completely from the vehicle. Either condition would impair handling and increase the chances of a crash. Dealers will inspect the torque on the ball stud joints on all front and rear lower control arms. If the torque is not to specification, the ball stud, knuckle, and nut will be replaced. If the torque is to specification, the dealers will replace only the ball stud nut and washer. The recall began August 24, 2004. The GM recall number is 04043.
The hydro-boost housing relief valve bore may be out of specification. The seal may fracture as a result, which may reduce braking assist and slightly increase the steering effort while braking. Under certain conditions, more braking effort will be required to stop the vehicle. Dealers will replace the hydro-boost relief valve. The recall began June 18, 2004. The GM recall number is 04004.
GM has recalled 1995-1997 Cadillac Deville, Eldorado, Seville, and Oldsmobile Aurora vehicles because the fuel rail and fuel system return line may crack and leak fuel. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will replace the fuel rail and return line.
GM recalls certain 2002-2003 Cadillac Devillle, Seville, Oldsmobile Aurora, and Pontiac Bonneville vehicles because the fuel tank pressure sensor may fail and cause a fuel leak. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will replace the fuel tank pressure sensor.
The front anchor tabs for the front bucket seats may not be engaged in the floor pan reinforcement slots and could potentially pivot rearward in a crash. This could increase the risk of injury to the seat occupant and a rear seat occupant. Dealers will ensure that both front anchor tabs are fully seated in the floor pan reinforcement slots. The recall began September 19, 2003. The GM recall number is 03050.
The owner's manual does not explain the child restraint anchor location symbols for the lower universal anchorage system. This does not meet the Federal Motor Vehicle Safety Standard. Owners were sent supplements to the owner's manual explaining the location symbols in the vehicle. The recall began August 18, 2003. The GM recall number is 03039.
