Defect description
VEHICLE DESCRIPTION: 4.4I SPORT UTILITY VEHICLES. OVER AN EXTENDED PERIOD OF TIME, ABRASION PARTICLES COULD DEPOSIT ON THE ELECTRICAL CONTACTS WITHIN THE SWITCH, CAUSING A DISRUPTION OF THE ELECTRIC CURRENT THROUGH THE CONTACTS. IF THE DISRUPTION OCCURS WHEN THE VEHICLE IS STATIONARY WITH THE TRANSMISSION IN THE NEUTRAL OR PARK POSITIONS, THE TRANSMISSION WILL SWITCH AUTOMATICALLY INTO THE EMERGENCY PROGRAM, WHICH IS DISPLAYED IN THE INSTRUMENT CLUSTER VIA A WARNING LAMP AND A MESSAGE, "TRANS. FAIL-SAFE PROG." IN THIS CASE, THE VEHICLE CAN BE DRIVEN IN LOWER GEARS ONLY WITH LIMITED ENGINE OUTPUT.
Safety risk
IF THIS PROBLEM OCCURS, THE ABILITY TO MAINTAIN SPEED IN TRAFFIC AND/OR ACCELERATE COULD BE GREATLY DIMINISHED, POSSIBLY LEADING TO A CRASH.
