Various 2020-2026 Ford and Lincoln vehicles equipped with blind spot information system (BLIS) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster (IPC). This may also be accompanied by diagnostic trouble codes (DTCs) B118C:11 and/or B118C:15 stored in the driver door module (DDM), and/or B118D:11 and/or B118D:15 stored in the passenger door module (PDM). This may be due to the wiring connector from the mirror to the BLIS module.

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 ↗Various 2019-2024 Ford and Lincoln vehicles equipped with SYNC 3 may experience a partially or fully black center display screen at start-up using Apple CarPlay or Android Auto. This does not affect rear camera operation. This may be due to interference from the phone being connected into the media hub using a universal serial bus (USB) cable during SYNC system boot up. To correct his condition, advise the customer to disconnect the USB cable from the phone. If the center display screen displays normally, reconnect the phone. If the concern persists, disconnect the phone from the USB cable, cycle the ignition off and open the driver's door so the interior lights come on. Close the door, star

The failure pattern owners describe
The 2020 Lincoln Corsair has serious electrical issues across multiple systems. The most common complaint is deep-sleep battery drain that occurs after the car sits unused for two weeks or more. The vehicle enters a low-power mode that continues draining the battery, requiring jump starts to restart. This triggers secondary faults in ABS, pre-collision assist, and hill-start systems due to low battery voltage.
Several owners report complete electrical system shutdown while driving with no warning. The battery tests fine but the system goes dead; you need a jump start or to disconnect the battery to restore power. One owner notes the emergency key won't unlock doors during these failures, creating a trapped-occupant hazard.
Infotainment and SYNC system problems are widespread: screens freeze and crash, software updates hang or fail, rearview cameras glitch, and the computer won't interface with dealer diagnostic equipment, preventing some recalls from being completed. Overhead interior lights turn on randomly at night, and moonroofs fail. One owner reports rat damage to soy-based wire insulation causing intermittent starting failures and engine shutdown while driving.
False safety system warnings also occur—pre-collision alarms trigger with no vehicles present, and navigation activates on its own. Finally, owners report active recalls with no available parts, with some dealers quoting 14+ month wait times.
Failure modes owners describe
