2014 Lincoln Navigator problems

Filed Sep 4, 2025 · Electrical, Engine · MO

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.

My vehicle exhibits an illuminated malfunction indicator light (MIL) and sometimes a wrench light in the instrument cluster. I had a diagnostic done on my truck to troubleshoot issue and the code was P0720. Ford issued a recall on Lincoln Navigator built between April 11, 2011 through August 19, 2013. My truck was built October 2013 and Tom Wood Ford of Indianapolis Indiana states my vehicle does not qualify for the recall and they want $1400.00 to repair the same issue as the recall notice. I was under the assumption that If an affected vehicle exhibits an illuminated malfunction indicator light (MIL) and/or wrench light in the instrument cluster with diagnostic trouble codes (DTCs) P0720, P0722, P0731 and/or P1500 stored in the PCM, dealers are to replace the molded leadframe and this service must be performed at no charge to the vehicle owner. I believe Ford/Lincoln still installed the faulty recalled parts on all Lincoln Navigators that were built the whole year in 2013. I would like for this expensive repair to be covered under the Ford Customer Satisfaction Program 19N01.

This vehicle was mis-built without its towing suspension system installed. The VIN and other manufacturer (mfg) -produced documents state that this vehicle has a self-levelling system which inflates suspension air bags upon connecting a trailer. However, this particular vehicle (per the dealership) is missing any type of self-levelling suspension system. This mis-build means that - when a trailer is connected - the headlights point upwards instead of front and/or slightly down to show the road conditions, which makes that alone a safety hazard. Upward lights may also impact oncoming traffic by blinding other drivers. My husband informs me there are other safety concerns that go along with this, but I do not understand all the physics of how towed vehicles operate so I cannot explain further how my safety, and possibly others, are risked when towing a load with this vehicle or others mis-built like it. The dealership purchased my vehicle back from me and it remains on their lot today instead of being sold at auction as stated. I found that another vehicle (2 years newer, but same mfg) was mis-built without its towing suspension system. I reported both issues to the dealerships. In the case of the potential replacement vehicle, I simply did not buy it. I reported both instances directly to the mfg and was told that was an issue for which the dealerships were responsible. I am concerned that this mfg has a known issue with a particular build of vehicle and is ignoring potential safety issues. I am concerned that their dealerships are also ignoring the problem instead of fixing it. I would like someone with more knowledge than me to investigate this matter and, if necessary, get the problems resolved to include further remuneration to me as applicable. I have documents, but am not sure what's relevant to upload. Thank you.
