Defect
Failure of two cast alloy rear suspension uprights have been reported. These failures resulted in detaching of the main wishbone mounting, and/or toe adjuster mounting from the main body of the rear upright. Fatigue related cracks have also been found in the body of the uprights. Both of these failures reported resulted in loss of vehicle control due to sudden loss of rear wheel location.
