Defect description
VEHICLE DESCRIPTION: CERTAIN 4-WHEEL DRIVE PICKUP TRUCKS AND SPORT UTILITY VEHICLES EQUIPPED WITH ABS (ANTILOCK BRAKING SYSTEM) MANUFACTURED FROM SEPTEMBER 1989 THROUGH AUGUST 1996. UNDER CERTAIN DRIVING CONDITIONS THE SWITCH WHICH SIGNALS THE ABS SYSTEM WHETHER THE VEHICLE IS IN 2-WHEEL OR 4-WHEEL DRIVE CAN MALFUNCTION CAUSING INCREASED STOPPING DISTANCES DURING ABS STOPS WHILE IN THE TWO-WHEEL DRIVE MODE.
Safety risk
IF THIS OCCURRED AT A TIME WHEN MINIMUM STOPPING DISTANCE WAS REQUIRED, A VEHICLE CRASH COULD OCCUR WITHOUT PRIOR WARNING.
Manufacturer remedy
DEALERS WILL REPLACE OR REPAIR THE 4-WHEEL/2-WHEEL DRIVE SWITCH.
SIGNIFICANT WEAR CAN DEVELOP ON THE LOW AND REVERSE CLUTCH PREVENTING THE PARK PAWL FROM ENGAGING. THIS CAN PREVENT A "NO PARK" CONDITION TO OCCUR WHILE THE ENGINE IS RUNNING, CAUSING UNINTENTIONAL MOVEMENT OF THE VEHICLE WITHOUT OPERATOR ACTION. (THE "NO PARK" CONDITION WILL NOT OCCUR WHILE THE ENGINE IS OFF.)
Safety risk
UNINTENTIONAL VEHICLE MOVEMENT COULD RESULT IN A VEHICLE ACCIDENT AND INJURY TO PERSONS IN THE PATH OF THE VEHICLE.
Manufacturer remedy
DEALERS WILL CHECK THE TRANSMISSION FLUID FOR CONTAMINATION WHICH WILL INDICATE IF THE LOW OR REVERSE CLUTCH IS WORN. IF THE TRANSMISSION FLUID SHOWS CONTAMINATION, THE TRANSMISSION WILL BE REPLACED.
Owner complaints
A complaint is one person's report to a federal agency. It is not a finding.
