2001 Ford Mustang

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.
