NHTSA Complaint #10058793 — 1996 FORD EXPLORER

MY 1996 EXPLORER IS A 5.0 LITRE AWD EDDIE BAUR PURCHSED USED. AFTER DRIVING USING THE CRUISE CONTROL WITHOUT INCIDENT, I PULLED INTO A PARKING LOT. COASTING SLOWLY INTO A PARKING SLOT APPLYING THE BRAKES, THE ENGINE APPEARED TO INCREASE POWER MAKING IT DIFFICULT TO STOP. THE MORE I PRESSED THE BRAKE PEDAL THE MORE THE ENGINE POWER INCREASED PREVENTING THE VEHICLE FROM STOPPING UNTIL COLLIDING WITH A VEHICLE IN FRONT. WITH THE BRAKE STILL APPLIED, THE ENGINE RACED WHEN PUT IN NUETRAL UNTIL SWITCHING THE IGNITION OFF. THE BRAKE AND ACCELERATOR OPERATED NORMALLY AFTER RESTARTING. DAMAGE RESULTED TO THE EXPLORER BUMPER. I DID NOT OBSERVE THE GAS PEDAL POSITION DURING THE INCIDENT BUT ASSUMED IT COULD HAVE BEEN DRIVEN BY THE CRUISE CONTROL CABLE UNDER UNCOMMANDED OPERATION AND SEVERED THE CRUISE CABLE BEFORE PROCEDING. A SIMILAR PROBLEM HAD OCCURED DURING A PRIOR STOP THE SAME TRIP BUT ABRUPTLY RETURNED TO NORMAL OPERATION POSSIBLY AFTER HAVING PUMPED THE BRAKES TO CHECK THEM. THE SAME TYPE PROBLEM WITH ENGINE POWER SURGE DURING BRAKING TO A STOP OCCURED ON PRIOR DAYS WHEN THE CRUISE CONTROL HAD NOT BEEN USED AND MAY HAVE CORRECTED AFTER PUMPING THE BRAKE. REVIEWING NHSTA COMPLAINT ODI ID 736277 AND SUBSEQUENT EXPERIMENT ON MY VEHICLE, IT APPEARS THE PROBLEM COULD POTENTIALLY RESULT FROM INADVERTANT PRESSING THE GAS PEDAL DURING BRAKING DUE TO PROXIMITY OF THE PEDALS BUT I CAN'T RULE OUT UNCOMMANDED CRUISE CONTROL OPERATION ACTIVATED BY A BRAKE SIGNAL. PLEASE ADVISE IF INVESTIGATION AND DISCOVERY HAVE RESULTED IN ANY PROBABLE CAUSES AND RECOMMENDATIONS FOR CORRECTIVE MAINTENANCE FOR THIS SAFETY HAZARD. DOES NOT DISPLAY SYMPTOMS CORRECTED BY RECALLS FOR THROTTLE BODY STICKING AND JAMMED CRUISE CONTROL CABLE.*AK
