Some 2021-2023 Nautilus vehicles may exhibit inoperative phone as a key and no communication with the remote function actuator (RFA) module. There may also be diagnostic trouble code (DTC) U0214 stored in various modules for loss of communication with the RFA module. To correct the condition, remove the RFA fuse (F19) located in the body control module (BCM). After one minute, reinstall the fuse to re-establish communication with the RFA module. Reprogram the RFA module using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14G617 and labor operations 12651D and 12651D4.

What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 10 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 2020-2022-Corsair, 2021-2023 Nautilus, 2020-2024 Navigator/Aviator, and 2021-2024 Mustang Mach-E vehicles equipped with phone-as-a-key may exhibit various phone-as-a-key concerns with diagnostic trouble codes (DTC) U200D:15, U200E:15, U200F:15, B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 stored in the remote function actuator (RFA) module. If any of these DTCs are detected during diagnostics, clear the DTCs, reprogram the RFA to the latest software level and start a new Ford Diagnosis and Repair System (FDRS) session. Verify that DTCs are no longer present. If only the B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 DTCs return i

full bulletin at NHTSA ↗Some 2021-2025 Ford and Lincoln vehicles equipped with SYNC4/Digital Experience may exhibit an unsuccessful telematics control unit module (TCU) software update or software activation during a universal serial bus (USB) update. This may be due to the vehicle connectivity setting being disabled.
full bulletin at NHTSA ↗Some 2021-2025 Ford/ Lincoln vehicles equipped with SYNC4 may not be able to perform an update to the accessory protocol interface module (APIM). This may be due to the software in the APIM. Ford Engineering has de-activated the ability to update these SYNC4 APIM modules as applicable, and the Ford Diagnosis and Repair System (FDRS) will not present an update for the APIM module. Some existing directed repairs may be impacted, check Professional Technician System (PTS) before attempting any specific technical service bulletin (TSB)/special service message (SSM) and check field service action (FSA) landing pages before attempting any FSA repairs.

The failure pattern owners describe
The 2007 Lincoln MKX electrical system shows a pattern of critical failures that owners link directly to engine management and power distribution. Most common is the ignition coil-to-PCM communication breakdown: multiple owners report coils burning out or failing to register with the computer module, triggering misfires, check-engine lights, and severe power loss on the highway. One owner couldn't exceed 45 mph; another lost power entirely at 65 mph. Dealer estimates for coil and computer repair run $2,400. A Ford service bulletin (TSB 14-0059) covers this for pre-March 2008 builds but no recall has been issued, despite owner complaints spanning the 2007–2009 model years.
Throttle sensor failure also appears, leaving the gas pedal unresponsive and stranding owners with $400+ repairs after the factory warranty expires. Stalling incidents without warning occur during normal driving, with one instance requiring dealer replacement of the computer module and battery—repairs that initially failed to hold.
Outside the engine bay, headlight harness connectors melt from internal heat, disabling the lights even though the bulbs work fine; one owner has already replaced both low-beam plugs twice. License plate lamp assemblies corrode in salt-exposure climates, creating short-circuit risk, yet Ford's recall for this defect excludes this 2007 model year. A single report documents power accessories (seat, windows, sunroof) operating independently when the vehicle is unlocked.
Failure modes owners describe
Ignition coil failures with PCM communication loss
Coil packs fail to be recognized by the engine control module, resulting in misfire and limp-mode operation. Multiple owners report replacing coils without resolving the issue because the computer does not register the new coils.
When: 66,000–106,000 miles; one case specifically noted after March (one year into ownership)
Symptoms owners cite: Engine hesitation and vibration; Check engine light illumination; Loss of power; unable to accelerate above 45 mph; Misfire condition; Sudden loss of power while driving at highway speeds
Codes mentioned: P0351, P0352, P0353, P0354, P0355, P0356
Repairs/costs cited: Dealer estimated $2,400 for coil and computer repairs; owners report coil replacement alone did not resolve the PCM communication fault
Recalls/TSBs owners mention: TSB 14-0059 issued March 20, 2014 (for vehicles built on or before 3/1/2008). No recall issued despite owner complaints identifying this as a pattern in 2007–2009 models.
Throttle position sensor malfunction
Throttle sensor fails to register pedal input, leaving the vehicle unresponsive to acceleration commands and triggering an emergency wrench warning light.
When: Post-warranty (approximately 5 years into ownership)
Symptoms owners cite: Gas pedal unresponsive; no vehicle acceleration regardless of pedal pressure; Emergency wrench warning light; Odometer displays zero mileage
Repairs/costs cited: Sensor replacement cost quoted at $400+
Recalls/TSBs owners mention: Owner references Ford claim website established to address this specific problem; no formal recall found in narratives
Stalling without warning
Engine stalls during normal driving with no prior indication. Diagnostic points to computer module fault; replacement of computer module and battery did not resolve the issue on first attempt.
When: 83,296 miles
Symptoms owners cite: Sudden stalling while turning; Complete stalling at 55 mph
Repairs/costs cited: Dealer replaced computer module and battery initially; issue recurred and required additional repair
Headlight harness and connector melting
Low-beam headlamp harness plugs experience thermal damage and melt, causing lights to lose electrical connection. Running light connectors also show heat damage. The bulbs themselves are functional; the receptacle connection fails.
When: Unspecified mileage; requires replacement multiple times
Symptoms owners cite: Melted headlight harness plugs; Heat damage to running light plugs; Lights fail despite functional bulbs
Repairs/costs cited: Owner has already replaced both low-beam headlight plugs and reports needing to replace them again
License plate lamp assembly corrosion
License plate light assemblies corrode and fail due to water intrusion, leading to electrical short-circuit risk. Recall 14V285000 addresses this on a narrow list of vehicles; this 2007 MKX exhibits the same defect but falls outside the recall scope.
When: Unspecified, but noted as occurring in salt-use climates
Symptoms owners cite: License plate light corrosion; Light assembly rusts and physically deteriorates when touched; One or both lights fail
Repairs/costs cited: Owner replaced failed assembly; corrosion risk on second light
Recalls/TSBs owners mention: Recall 14V285000 (NHTSA Campaign) issued for exterior lighting corrosion, but does not cover this 2007 MKX
Unintended electrical actuation of power accessories
Power-operated components (driver seat, windows, sunroof) move independently when the vehicle is unlocked with the engine off, suggesting a control module or wiring fault.
When: 62,225 miles
Symptoms owners cite: Front driver seat moves forward and backward without input; All windows and sunroof open and close independently during unlock; Passenger airbag off warning light illuminates while driving
Repairs/costs cited: Vehicle was not diagnosed or repaired
