2000 Ford Mustang

On certain Mustang SVT vehicles, when operated in severe driving cycles such as frequent drag race type standing start acceleration, the ball joint in the rear suspension knuckle where the lower control arm attaches may be displaced longitudinally out of its installed position.  If this occurs, the stress levels in the knuckle casting will increase and the casting may fracture. The corner of the vehicle will then drop and the lower control arm may contact the inside of the wheel, possibly affecting directional control.  Correction:  Dealers will install a revised rear suspension knuckle assembly with positive retention of the ball joint.

On certain vehicles equipped with manual transmissions, if parked with the parking brake not fully applied and not in first gear, as directed in the Owner Guide, and the self adjustment pawl subsequently skips one or two teeth, the vehicle could move on some grades. This could result in unintended vehicle movement and a vehicle crash without prior warning.  Correction:  Dealers will modify the parking brake control and install a plate or over-bracket to the control to lock the self adjust mechanism in position following adjustment.

Certain Mustang GT vehicles may not comply with C.M.V.S.S. 103 - Windshield Defrosting and Defogging.  Coolant flow blockage at the intake manifold heater core nipple results in no coolant flow to the heater and, therefore, no warm air flow from the heater or windshield defroster.  Correction:  Dealers will repair the heater core nipple blockage and restore coolant flow.
