2014 Lincoln Navigator

the vehicle's antitheft system automatically triggers. There are two different events here: 1. Anti theft system triggers when the engine is off. When I attempt to start the car, the engine will not activate. By going through a series of locking and unlocking attempts (via key fob, via door locks, via keyless entry) I can eventually get the engine started. This event happens every other day. 2. Anti theft system triggers when the engine is on, while driving on the road. This results in the engine shutting off, and both the steering wheel and brake pedal locking up. I took the vehicle to a Lincoln dealer (Dave Sinclair Lincoln St. Louis) and after running diagnostics they suspect the root cause is due to an Apple Air tag that is attached to the key ring of the key I'm using, and the PATS sensor module mounted to the bottom of the lock cylinder could be triggering/sensing a security event as a result. I do not think a reasonable resolution to prevent future issues is to not have an air tag (or similar device) in the vehicle. The anti theft system triggering when the engine off is an inconvenience. However, the anti theft system triggering while the car is in motion is a major safety hazard.

DRIVING AT ABOUT 25-30 MPH ON SIDE STREET AND MY CAR SURGED OUT OF CONTROL.. I ATTEMPTED TO CONTROL THE SPEED WITH THE BRAKE. I WAS ABOUT 100-150 FEET FROM A BUSY INTERSECTION (40 HIGHWAY -THE CAR SURGING REALLY FAST. I NEEDED TO MAKE SOME QUICK DECISIONS TO PROTECT A LOT OF PEOPLE FROM BEING BADLY INJURED OR KILLED. I HAD TO LEAVE THE KEY ON SO THAT I COULD CONTROL THE CAR AWAY FROM 40 HIGHWAY- SO I TURNED INTO A LITTLE PATH TO MY RIGHT WHICH LED ME INTO BIG TREES OR A THICKET. I CHOSE THE THICKET NOT KNOWING THERE WAS A TERRAIN IN THE MIDDLE. ACTUALLY , THE CAR WAS GOING SO FAST - I HAD VERY LITTLE CONTROL AT THIS TIME. MY CAR ATTEMPTED TO GO UP ON ONE SIDE FLEW ABOUT 20 FEET THROUGH THE AIR WHEN IT LANDED A SMALL TREE KEPT IT FROM ROLLING OVER AND CAME OUT ON A HILL AGAIN HEADING FOR THE BUSY 40 HIGHWAY. AS LUCK WOULD HAVE IT ,THE HILL WAS WET AND MUDDY FROM RAIN AND I PULLED THE STEERING WHEEL AS HARD AS I COULD TO MY RIGHT TURNING THE CAR UP THE HILL - AWAY FROM THE TRAFFIC. THE SOFT GROUND HELPED TO PUT THE CAR IN A SKID AND FLIPPED THE BACK END AROUND. AS IT WAS HEADING UP THE HILL I QUICKLY TURNED OFF THE KEY AND GOT THE CAR STOPPED. WHEN THE TOWING COMPANY CAME TO PICK UP THE CAR -UNSAFE STILL SURGING. TOOK CAR TO BOB SIGHTS FORD . ( PREVIOUSLY,THEY REPAIRED THE POPPING NOICE DESCRIBED IN ANOTHER 'NATHSA' COMPLAINT. ) CAR WAS TOTALED. I TRIED TO GET THEM TO HOOK THE CAR UP TO THE MECHICANICAL MODULE SCANNER FOR THE SAFETY OF OTHERS. INSTEAD THEY PUT IT ON THE BODY SCANNER THEY USE TO LOCATE ALL COMPONENTS WHEN REPAIRING A WRECKED CAR (WHICH I PAID FOR) WOULD NOT PUT THE CAR ON THE MECHNICAL SCANNER EVEN THOUGH IT WAS STILL SURGING WHEN I FINALLY RELEASED IT TO THE INSURANCE COMPANY. MY BIGGEST CONCERN IS THE SAFETY OF OTHERS. I EVEN TALKED TO ONE OF THE OWNERS OF THE DEALERSHIP.
