Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how

What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some 2012-2020 Ford and Lincoln vehicles equipped with a TCU may exhibit an inoperative remote start with a 'Vehicle Failed To Start' message when using MyFord Mobile/Ford Pass/Lincoln Way mobile applications. The cellular cloud systems will only allow two remote start requests from the MyFord Mobile/Ford Pass/Lincoln Way apps without a vehicle drive event occurring. If a third remote start request is received, a Vehicle Failed To Start message will be displayed quickly in the mobile app. Once the vehicle is driven, the remote start counter is reset and will allow remote start commands to be sent from the mobile app. If the remote start system is not functioning using the key fob, refer to W
full bulletin at NHTSA ↗For Ford and Lincoln vehicles that require positive or negative battery terminal replacement, it is not necessary to replace the complete battery cable harness (14300 and 14301) for this concern. Positive battery cable clamp BT4Z-14450-AA and negative battery cable clamp BT4Z-14450-BA are available for this type of repair. Do not cut or shorten the battery cable, instead carefully remove the affected battery cable clamp and clean the cable end as necessary to preserve wire length. Some rework may be necessary for some vehicle environments. Bend the new positive battery cable clamp as needed and crimp it to the existing battery cable. Make sure to use heat shrink tubing over the battery cable

The failure pattern owners describe
The primary complaint across 14 narratives centers on a door-ajar warning system that malfunctions dangerously. The latch sensor mechanism falsely tells drivers doors are closed when the latch has engaged but the door itself isn't secured to the body. Owners describe the dashboard warning light flagging a door as ajar when it's firmly shut, or failing to warn when doors are genuinely unsecured. This causes interior lights to stay on continuously, drains batteries, prevents door locks from engaging even while driving, and triggers the alarm horn to blast unexpectedly at 2 a.m. or mid-sermon. One owner discovered—only because his wife noticed—that a rear passenger door appeared closed according to the latch sensor but was unlatched to the vehicle while his eight-year-old daughter sat in the seat. Owners point directly to Ford's design choice to place the closure sensor on the latch itself rather than on the vehicle body.
Secondary electrical issues include infotainment touchscreen blackouts lasting days or weeks, a backup camera that displays inverted or shuts down in motion, and nonfunctional collision-avoidance sensor warnings. One dealer replaced a defective APIM module and charged $965.64. Independent diagnostics have come back clean while failures persist, leaving owners frustrated and out of pocket for repairs Ford reportedly charges $500 per incident to fix.

Failure modes owners describe
Door ajar sensor / latch switch false reporting
The door ajar warning system falsely indicates a door is open when it is actually closed, or fails to detect when a door is truly open. The root cause cited by owners is that Ford placed the door-closure sensor on the latch mechanism itself rather than on the vehicle body. This design flaw allows the latch to close while the door remains unlatched to the body, creating a dangerous disconnect between what the system reports and actual door security.
When: Occurs intermittently and continuously; happens while driving and parked; one owner reports issue ongoing since vehicle purchase
Symptoms owners cite: Dashboard warning light falsely indicates door is ajar when door is firmly closed; Dashboard warning light fails to indicate door is ajar when door is actually open; Interior and puddle lights remain on due to false ajar signal; Doors fail to lock even while driving; Vehicle alarm (horn) activates unexpectedly while parked, sometimes multiple times daily (2-4 times); Latch closes mechanically but door remains unlatched to vehicle body
Repairs/costs cited: Owners report repair costs up to $500 for switch/sensor replacement; one owner disconnected battery at night to prevent battery drain; diagnostics at independent shop found nothing wrong via computer scan
Recalls/TSBs owners mention: No recalls or TSBs mentioned by any owner; issue reported as ongoing for years on Lincoln MKX and Ford Edge
Touchscreen APIM (Infotainment) failure / blackout
The touchscreen/infotainment system goes black and becomes unresponsive for extended periods. One owner had the APIM (Accessory Protocol Interface Module) diagnosed as defective and replaced by a dealer; another owner suspects a faulty chip on the computer board. The failure persists even after fuse changes.
When: Began in 2017; worsening pattern through 2019; one case at 60,759 miles; recurring every other week to weeks-long outages
Symptoms owners cite: Touchscreen goes black and does not respond; Sync system fails to update properly; Rear camera does not work; Blind spot warning system does not function; Rear cross-traffic warning does not function
Repairs/costs cited: One owner paid $965.64 for APIM replacement and PMI update at dealer (October 2019); fuse replacement did not resolve issue
Recalls/TSBs owners mention: Dealer-replaced APIM unit with software update (PMI)
Rear camera / backup camera malfunction
Backup camera either does not function at all or displays the image inverted (upside down). One owner reports the camera changed orientation and then shut down while in motion.
When: Occurs while driving and parked; one report of shutdown occurring during motion
Symptoms owners cite: Backup camera does not display image; Backup camera displays image upside down; Camera switches from vertical to horizontal orientation unexpectedly; Camera shuts down while vehicle is in motion
Collision avoidance sensor blockage warnings
The vehicle displays a sensor blockage warning for collision-avoidance systems while driving, indicating the sensors are blocked or malfunctioning. The cause and whether the sensors are actually obstructed is unclear from the narrative.
When: Occurs while driving on the highway
Symptoms owners cite: Dashboard warning: collision avoidance sensors reported as blocked while in motion
Power trunk / rear hatch control failure
The power buttons for opening and closing the rear hatch do not function properly or at all.
Symptoms owners cite: Rear hatch buttons do not open or close the rear door properly
Sunroof malfunction
The sunroof fails to fully open whether the vehicle is parked or in motion.
Symptoms owners cite: Sunroof does not fully open when parked; Sunroof does not fully open while driving
Infotainment system power loss
The entertainment system and touchscreen turn off and will not power back on while the vehicle is running and parked.
Symptoms owners cite: Entertainment system shuts off and fails to power on

While driving on the highway, brake pedal goes to the floor board. Replaced rotors brake pads and calipers. A couple of weeks later, pedal goes to floorboard again. Replaced master cylinder, but was told it was probably the ABS booster. Needs to be a recall. This is the 60 th complaint. Also back up camera is upside down.
The rear passenger door latch mechanism closed without the door actually being closed. This caused a false positive condition for the "door ajar" warning system. I thought that the door was secure, however the door was in fact not latched to the vehicle. My eight year old daughter was sitting in the seat. Were it not for the perception of my wife who suspected that the door was insecure I would…
