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 11 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.
Certain 2011 - 2013 Model Year F-150 and 2012- 2013 Model Year Expedition/Navigator Vehicles Equipped with A 6R80 Transmission Transmission Molded Leadframe Extended Coverage In some of the affected vehicles, an output shaft speed (OSS) sensor failure may result in 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 powertrain control module (PCM).
full bulletin at NHTSA ↗Some 2003-2020 Expedition/Navigator and 2006-2020 F-150 vehicles equipped with TOD transfer cases may exhibit grinding/clicking/ratcheting noise from the front wheel area. This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure steps to remove and cap the vacuum supply line.
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
full bulletin at NHTSA ↗Some 2009-2017 Expedition/Navigator, 2009-2014 F-150/Mustang, 2008-2009 Sable, 2008-2019 Taurus/Flex/MKT, 2013-2019 Police Interceptor Sedan/Utility, and 2011-2019 Explorer vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings. This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness (14S411) to the blower motor speed control is also recommended to avoid repeat repairs. Use pigtail harness service part numbers 3U2Z-14S411-ZEA or CU2Z-14S411-FA, as both parts are interchangeable. Refer to Wi

The failure pattern owners describe
The 2012 Expedition's electrical system has serious reliability issues. Multiple owners report sudden downshifts into first gear while driving at highway speeds, accompanied by speedometer failure, gauge cluster flashing or going blank, and temporary loss of throttle response. These events happened repeatedly for some owners—one saw eight incidents in 2,000 miles. Ford issued a recall for this transmission lead frame defect, but some affected VINs were excluded from that recall despite identical symptoms. Owners report turning the vehicle off and restarting sometimes restores function temporarily.
A critical fuel system hazard emerged in at least one case: the internal power wire to the fuel pump rubbed through on the pressure regulator spade inside the fuel tank, creating a short that blew fuses, caused stalling, and melted safety wires. That vehicle caught fire and became a total loss. Another owner reported an engine fire from the undercarriage.
Instrument cluster failures are common, with speedometers dropping to zero and entire gauge panels going blank during highway driving. One owner reported a third brake light housing melting from heat. Dealers quoted $900 for lead frame replacement, but many vehicles were never repaired; some owners were told there was no recall coverage.

Failure modes owners describe
Transmission lead frame / output speed sensor failure causing sudden downshift
The transmission output speed sensor mounted in the lead frame fails, triggering an unintended downshift into first gear at highway speeds. This causes sudden deceleration, RPM spike, and loss of vehicle control.
When: Occurs during highway driving; reported at various speeds (50-65 mph). One owner experienced it 8 times in 2,000 miles.
Symptoms owners cite: Sudden downshift into first gear; Engine RPM spike; Loss of throttle response temporarily; Abrupt deceleration and bucking; Speedometer stops working or reads zero; Gauge cluster flashing or blank; Wrench light illuminated; Fuel level low light and tire pressure sensor fault light illuminate; Traction issues or rear wheel slide potential at speed
Codes mentioned: Transmission output speed sensor fault, Service Advance Trac code, Tire Pressure Monitor Fault code
Repairs/costs cited: Sheehy Ford quoted $900 for new lead frame. Some owners reset issue temporarily by turning vehicle off and restarting; one owner had to cycle through manual gears and 4WD toggle to restore normal operation.
Recalls/TSBs owners mention: Ford issued a recall (2011–2012 F-150, 2012 Expedition with 6R80 transmission built Aug. 19, 2011–Dec. 19, 2011 at Kentucky Truck Plant). However, some affected VINs were not included in the recall despite having identical symptoms.
Fuel pump internal wiring short circuit and fire hazard
The internal power wire to the fuel pump rubs through on the pressure regulator ground spade, creating a short circuit inside the fuel tank. This blows fuses, causes stalling, melts safety ground wires, and presents high risk of fire.
When: Occurred during regular driving; customer stalling complaint triggered diagnosis.
Symptoms owners cite: Vehicle stalling without warning; Electrical burning smell; Smoke from undercarriage; Entire vehicle fire (one catastrophic case)
Codes mentioned: Fuse 44 blown in underhood fuse box
Repairs/costs cited: Factory OE Motorcraft fuel pump assembly affected. Removal and inspection revealed melted safety ground wire between fuel pump and pressure regulator. One owner's vehicle became a total loss due to fire.
Instrument cluster / lead frame electrical failure
The instrument cluster lead frame fails electrically, causing the speedometer and gauges to stop functioning. In some cases the entire cluster goes blank.
When: Occurred at highway speeds (50 mph reported). One vehicle had failure at 95,000 miles, another at 98,000 miles.
Symptoms owners cite: Speedometer stops working or drops to zero; Gauge cluster goes blank without warning; Miles to empty display shows zero with no numbers
Codes mentioned: Molar lead frame failure
Repairs/costs cited: Dealers diagnosed need for lead frame replacement but vehicles were not repaired. No cost estimates provided by owners.
Recalls/TSBs owners mention: One owner reported Ford opened case 13199951 and was referred to NHTSA. Another was told by dealership there was no recall.
Third brake light housing overheating and melting
Stock Ford third brake light housing overheats due to the lighting assembly, melting the housing in the frame.
When: Discovered during routine vehicle use; timing not specified.
Symptoms owners cite: Burning plastic smell from rear of vehicle; Third brake light housing melted and discolored from heat
Repairs/costs cited: Stock Ford housing with Ford-installed lights. No repair details provided.
