2014 Lincoln Navigator problems

“The contact owns a 2014 Lincoln Navigator. The contact stated while driving 60 MPH, the transmission unexpectedly downshifted to a lower gear, and the vehicle decelerated to 25 MPH within 4-5 seconds. The power train warning light was illuminated. The contact pulled over to the side of the road and turned off the vehicle. The contact stated that upon restarting the vehicle, the warning light was no longer illuminated, and the vehicle responded as needed while driving. The vehicle was taken to Firestone, where DTC: P0722 was retrieved, and the vehicle was diagnosed with output shaft speed sensor failure. The vehicle was taken to the dealer, where the contact was informed that the VIN was not included in a related recall. The vehicle was being repaired. The manufacturer was notified of the failure and informed the contact that the failure was not related to a recall. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 60,000.”

“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…”

“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…”

“THE SPEEDOMETER WOULD INTERMEDIATELY STOP WORKING. WHEN THIS IS HAPPENING IT WOULD HAVE A LOSS IN POWER OR BEGIN TO MISFIRE. WE HAVE NOW STOPPED DRIVING THE VEHICLE BECAUSE IT DOWN SHIFTED EXTREMELY HARD AT ROAD SPEED WHILE ALONG SIDE ANOTHER VEHICLE. THE WIFE WAS EXTREMELY SCARED AND I AM AFRAID IT WILL HAPPEN AGAIN AND CAUSE DAMAGE TO THE TRANSMISSION.”

“The contact owns a 2014 Lincoln Navigator. The contact stated while driving at an undisclosed speed, after activating the HVAC system, she heard an abnormal rumbling sound coming from behind the dashboard. As a result, the contact stated that she was unable to fully use the HVAC system, including the defroster, potentially reducing front windshield visibility. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the blower motor. The vehicle was not repaired. After investigating the failure, the contact related the failure to Customer Satisfaction Program: 22S56 (HVAC), but the VIN was not included. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 122,000.”
