WHILE TAKING MY KIDS TO DAYCARE THE ENGINE FAIL SAFE LIGHT CAME ON AND THE ENGINE SHUT DOWN. I WAS SITTING AT A LIGHT WAITING TO GO STRAIGHT UNDER A BRIDGE AND AT THIS PARTICULAR LIGHT ONLY ONE LANE CAN GO STRAIGHT SINCE THE ENGINE SHUT DOWN AND I COULD NOT MOVE THIS CAUSED MAJOR BACKUP. LUCKILY THERE WAS AN EMERGENCY VEHICLE A FEW CARS BEHIND AND HE WAS ABLE TO PUSH ME THROUGH THE LIGHT AND INTO A PARKING LOT. AFTER A FEW MINUTES OF SITTING THERE THE TRUCK STARTED AND I WAS ABLE TO GET THEM TO DAYCARE AND CONTINUE ON TO WORK. VERY DANGEROUS SITUATION AND SOMETHING SHOULD BE DONE.

MY VEHICLE HAS COMPLETELY SHUT DOWN IN THE MIDDLE OF DRIVING ON SEVERAL OCCASIONS. I HAVE HAD DIAGNOSTIC REPORTS RUN AND THEY DO NOT FIND ANY PROBLEMS. THE FIRST TIME I WAS GOING 45 MPH AND WAS ABLE TO COAST INTO A SONIC. I WAITED ABOUT 15 MINUTES AND THE CAR STARTED BACK UP. THE SECOND TIME WAS AT A GAS STATION AND MY CAR WOULD NOT START. I HAD A DIAGNOSTIC RUN AND WAS TOLD IT WAS MY BATTERY. I REPLACED THE BATTERY AND MY VEHICLE DIED AGAIN THE NEXT DAY, BUT STARTED BACK UP ONE I LET IT SIT FOR A FEW MINUTES. THIS MORNING I WAS PULLING INTO A PARKING LOT AT WORK AND IT DIED. AFTER ABOUT 10 MINUTES IT STARTED BACK UP AND I WAS ABLE TO PULL INTO A PARKING SPOT. I WENT TO LEAVE FOR LUNCH AND NOW MY VEHICLE WILL NOT START AT ALL. THIS COULD HAVE BEEN MUCH WORSE IF I WERE DRIVING DOWN THE INTERSTATE AND THE CAR SHUT OFF ON ME LIKE IT HAS DONE OTHER TIMES. I HAVE TWO CHILDREN AND THE THOUGHT OF THEM IN THIS CAR DOES NOT MAKE ME FEEL SAFE!!

THE ENGINE SHUT OFF, BUT LUCKILY I STILL HAD FULL MOVEMENT OF MY STEERING WHEEL SO I WAS ABLE TO CHANGE LANES AND GET OFF TO THE SHOULDER. I PANICKED FOR A MOMENT, BUT STARTED THE CAR AND IT STARTED RIGHT BACK UP. I ATTEMPTED MY DRIVE TO WORK AND MADE IT THERE. NOT SURE WHAT TO DO ABOUT THE PROBLEM, BUT I'M SCARED TO DRIVE IT ANYMORE. ESPECIALLY WITH MY CHILDREN IN THE VEHICLE AND MY HUSBAND IS OUT OF TOWN FOR WORK. THIS IS A MAJOR SAFETY ISSUE AND NEEDS TO BE RECALLED.

Structure
THE PAINT ON THE LIFT GATE IS BUBBLING AND PEELING, CAUSED BY A PROBLEM WITH THE ALUMINUM. A PROBLEM THAT FORD WAS AWARE OF BEFORE MY CAR WAS SOLD.
ON CERTAIN TRUCKS, PASSENGER CARS AND SPORT UTILITY VEHICLES, THE WINDSHIELD WIPER MOTOR MAY HAVE BEEN PRODUCED WITHOUT GREASE BEING APPLIED TO THE OUTPUT SHAFT GEAR.
Consequence & remedy
Consequence: AFTER A PERIOD OF CONTINUOUS USE ON THE HIGH SPEED SETTING, LACK OF GREASE ON THE OUTPUT SHAFT GEAR MAY CAUSE THE GEAR TO DISTORT OR FRACTURE DURING OPERATION RESULTING IN A LOSS OF WIPER FUNCTION. INOPERATIVE WIPERS UNDER INCLEMENT WEATHER CONDITIONS COULD CAUSE A CRASH DUE TO IMPAIRED VISIBILITY.
Remedy: DEALERS WILL INSPECT THE WIPER MOTOR FOR THE PRESENCE OF GREASE AND GREASE THE WIPER MOTOR GEARS IF NECESSARY. THE RECALL BEGAN ON NOVEMBER 22, 2005. OWNERS MAY CONTACT FORD AT 1-800-392-3673 OR LINCOLN/MERCURY AT 1-800-521-4140.
ON CERTAIN SPORT UTILITY VEHICLES, THE FRONT AND REAR TIRES ON THE DRIVER'S SIDE OF AFFECTED VEHICLES MAY HAVE BEEN DAMAGED AT THE CENTER TREAD DURING PRODUCTION.
Consequence & remedy
Consequence: OVER TIME, THE DAMAGE MAY BE SUFFICIENT TO ALLOW BELT CORROSION ULTIMATELY LEADING TO A TREAD SEPARATION, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSPECT ALL FOUR TIRES (TO ENSURE INSPECTION OF THE LEFT HAND SIDE TIRES THAT MAY HAVE BEEN ROTATED TO THE OTHER SIDE OF THE VEHICLE) FOR TIRE TREAD DAMAGE AND, IF NECESSARY, REPLACE THE DAMAGED TIRE. THE RECALL BEGAN ON JULY 13, 2005. OWNERS MAY CONTACT FORD AT 1-800-392-3673.
