FOR A SIGNIFICANT AMOUNT OF THE VEHICLE'S LIFE, THE AIRBAG LIGHT HAS ILLUMINATED A MAJORITY OF THE TIME. I DID NOT BELIEVE THIS WAS AN ISSUE AS I WAS INSTRUCTED THAT A LIGHT WOULD COME ON IF THE VEHICLE THOUGHT SOMETHING/SOMEONE WAS IN THE PASSENGER SEAT, BUT DID NOT MEET MINIMUM WEIGHT REQUIREMENTS. IT HAS COME TO MY ATTENTION WHEN MY VEHICLE WAS IN FOR A NON-RELATED REPAIR, THAT THIS IS NOT THE CASE AND THAT THE LIGHT ACTUALLY INDICATES A FAULT WITH THE AIRBAG SYSTEM. SO I HAVE BEEN DRIVING AROUND FOR PROBABLY 40,000 MILES WITH FAULTY AIRBAGS IN THE CAR IN WHICH I AM THE ORIGINAL OWNER. I CALLED FORD WHO EXPRESSED LITTLE TO ZERO CONCERN UNTIL I LET THEM KNOW I WOULD BE FILING A COMPLAINT. ACCORDING TO THE DEALER, THE ISSUE IS THAT THE CONNECTORS ARE CORRODED (THE INDICATION WAS MULTIPLE CONNECTORS ARE CORRODED). THIS SEEMS LIKE A REALLY BIG ISSUE - I LIVE IN OREGON, SO NOT QUITE A DRY CLIMATE, BUT IT'S NOT ABNORMAL. THE PERSON I SPOKE TO AT FORD WAS NAMED "ANN"

I FOUND CRACKS IN THE DOOR JAM OF THE REAR LIFTGATE ON THE DRIVER'S SIDE OF THE VEHICLE. FOLLOWING THIS DISCOVERY I FOUND FLOOR BOARDS SOAKED IN WATER, WATER DRIPPING DOWN MY 3RD ROW SEAT BELT ONTO THE FLOOR BOARDS AND INTO THE SPARE TIRE WELL. FOLLOWING THIS MY MOONROOF QUIT WORKING. THEN I RECEIVED A LETTER REGARDING EMISSIONS ENTERING THE BACK OF THE VEHICLE AND CAUSING PEOPLE TO PASS OUT AND WRECK THEIR VEHICLES. TOOK THE CAR TO FORD AND THE FORD DEALERSHIP WON'T COVER THE CRACKS IN THE NON WRECKED VEHICLE UNDER THE EMISSIONS WARRANTY BECAUSE THEY STATE THEY ARE UNRELATED. IF WATER IS GETTING INTO THE BACK OF THE CAR THROUGH A CRACK THEN EMISSIONS PROBABLY ARE TOO.

AFTER STARTING THE CAR WHILE PARKED THE 'SERVICE ADVANCE TRAC" WARNING CAME ON. AFTER DRIVING APPROX. 100 FEET THE WARNING WENT AWAY. THERE WAS A SLIGHT HARDNESS IN THE STEERING AT THIS TIME. THAT WENT AWAY WHEN THE WARNING WENT AWAY. THIS OCCURRED ON NOV. 10, 2017. THE SECOND PROBLEM OCCURRED ON NOV. 23, 2017. WHILE PARKED OVERNIGHT AND ALL DAY IN OUR GARAGE I STARTED THE CAR AND THE "POWER STEERING ASSIST FAULT'' WARNING CAME ON. I COULD NOT TURN THE STEERING WHEEL AT ALL. I TURNED OFF THE ENGINE AND WITHIN 10 TO 15 SECONDS I STARTED THE CAR AGAIN. NO WARNING CAME ON AND THE POWER STEERING WORKED O.K. I STARTED THE CAR AGAIN THIS MORNING AND NO WARNING OR PROBLEM.
