NHTSA Complaint #10152067 — 1996 FORD WINDSTAR

ENGINE DIES AFTER EITHER VERY SHORT (1 SECOND OR LESS) OR NO MISFIRE. ALWAYS ON HOT AFTERNOON AFTER LONG PERIOD HIGHWAY DRIVING, TYPICALLY INTERSTATE WITH SPEED IN THE 70'S. ONLY ONCE ON A SECONDARY ROAD SPEEDS OF 45 - 50. ALL TIMES IN THE ROLLING HILLS OF UTAH, WYOMING, AND WESTERN NORTH DAKOTA. ALL SIX INCIDENTS OCCURRED DURING A CROSS COUNTRY TRIP IN JULY, 2005 WITH ODOMETER READINGS IN THE 70,000'S. TYPICALLY, WHEN IT HAPPENS, THE ENGINE SPEED AND THROTTLE ARE CONTINUALLY ADJUSTING TO MAINTAIN SPEED ACROSS THE HILLS. FIRST INDICATION OFTEN IS SIMPLY THE CAR SLOWING DOWN RATHER THAT CRUISING ALONG. ALL OTHER ELECTRICAL (AIR, RADIO, WINDOWS, ETC) NOT AFFECTED. THIS IS VERY DANGEROUS. OTHER THAN SOMETIMES A ONE SECOND MISFIRE, THERE IS NO WARNING. THE CAR MAY BE PASSING A TRUCK, IN A MIDDLE FREEWAY LANE, ON ON A ROAD WITH NO SHOULDER WHEN IT HAPPENS. WHEREVER AND WHENEVER IT HAPPENS, THE CAR SIMPLY COASTS AS THE DRIVER PULLS OFF THE ROAD TO EXTENT POSSIBLE. THE ENGINE WILL NOT RESTART FOR 15 MINUTES OR SO. THEN IT STARTS AS IF NOTHING EVER HAPPENED, AND CAR IS GOOD UNTIL THE NEXT INCIDENT. I MADE DETAILED NOTES OF EACH INCIDENT, AND CAN PROVIDE ADDITIONAL INFO ON SPECIFICS OF WHAT WAS GOING ON WITH CAR AT THE TIME. I TOOK CAR TO A FORD DEALER. THE DEALER DID DIAGNOSTICS AND COULD NOT IDENTIFY PROBLEM. I HAVE REFRAINED FROM DRIVING UNDER SIMILAR HIGHWAY CONDITIONS SINCE THEN. THE VAN WAS PURCHASED NEW IN CONNECTICUT IN FEB, 1997. *NM
