THIS BULLETIN IS BEING REVISED TO ADVISE DEALERS TO ORDER LOWER CONTROL ARMS AND KNUCKLES, IF NECESSARY,
FROM GMSPO RATHER THAN THE PQC.
THIS BULLETIN CANCELS AND REPLACES BULLETIN 04043A ISSUED SEPTEMBER 2004. PLEASE DISCARD ALL COPIES OF
BULLETIN 04043A.
Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2004 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 the 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.
Correction
Dealers are to install a new nut and washer, and if required, replace the ball stud and/or steering knuckle.
