THE IGNITION LOCK CYLINDER MAY HANG UP AND NOT FULLY RETURN TO THE "ON" POSITION FROM THE "START" POSITION AFTER STARTING THE ENGINE. IF THIS OCCURS, THE ENGINE WILL REMAIN RUNNING, BUT THE BATTERY CURRENT TO THE BRAKE SYSTEM SUPPLY MOTOR WILL BE INTERRUPTED. CONSEQUENCE OF DEFECT: WITH POWER TO MOST ACCESSORIES AND THE BRAKE SYSTEM SUPPLY MOTOR INTERRUPTED, THE POWER ASSIST TO THE FRONT BRAKE WILL BE LOST AND AFTER ABOUT 10 TO 15 NORMAL BRAKE STOPS, LOSS OF REAR BRAKE FUNCTION WILL RESULT, CAUSING INCREASED STOPPING DISTANCE. HOWEVER, THE INSTRUMENT BRAKE WARNING LIGHT WILL ILLUMINATE PRIOR TO REDUCED BRAKING CAPABILITY AND IF WARNING IS NOT HEEDED, AN ACCIDENT MAY OCCUR.
REPLACE IGNITION LOCK CYLINDERS WITH REVISED DESIGN CYLINDERS.
