2004 Cadillac XLR: Recall Notice: Lower Control Arm Ball Stud Washer
Recall Bulletin 04043 – Lower Control Arm Ball Stud Washer
Date: August 2004
Subject: 04043 – Lower Control Arm Ball Stud Washer
Models: 2004 Cadillac CTS, SRX and XLR
2004 Chevrolet Corvette
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2004 model year Cadillac CTS, SRX, and XLR, and Chevrolet Corvette vehicles. Washers that are used along with nuts to attach the lower control arms were made of the wrong steel material. These washers may fracture and become loose or fall away from the vehicle, making it possible for the control arm to separate. If this were to occur on the front of the vehicle, the affected corner of the vehicle will drop and the affected wheel could tilt outward, creating a dragging action that would tend to slow the vehicle and turn it in the direction of the affected corner. The driver could maintain some steering control with the unaffected wheel, but vehicle control would be diminished. If the separation occurs at the rear of the vehicle (XLR and Corvette only), it could cause unexpected right or left lateral forces at the rear of the vehicle. Although steering of the front wheels would be unaffected, control of vehicle direction would be impaired.
Front or rear control arm separation may also reduce brake system performance and increase stopping distance.
If these events occur and the driver is unable to react in time, a crash could occur.
Dealers are to install a new nut and washer, and if required, replace the ball stud and/or steering knuckle.
