Service bulletins for the 2020 Lincoln Aviator

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

26N092026-07-01. Other. VISIBILITY/WIPER. Customer Satisfaction Program 26N09 Certain 2020 Model Year Escape, 2020-2021 Corsair, 2020-2021 Aviator, and 2020- 2021 and 2023 Explorer Vehicles Front Windshield Wiper Motor Replacement, if Required After Dealer Evaluation
SSM 523732024-04-04. Service bulletin. EQUIPMENT; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some 2020-2024 Aviator vehicles equipped with auto air refresh option (minor feature code G1DAG) may exhibit a buzzing/clicking/humming/ticking sound from the OHC and/or diagnostic trouble code (DTC) P24AE in the heating ventilation and air conditioning (HVAC) module. To confirm if a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). If diagnostics lead to the in-vehicle temperature and humidity sensor as the causal part, a new lower level part is available. It is not necessary to replace the OHC assembly if only the sensor is suspect. Use part number L1MZ-19F666-A to resolve the concern.
SSM 512652023-01-06. Service bulletin. VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR; EQUIPMENT. Some vehicles equipped with power folding mirrors may exhibit power folding mirrors that are inoperative or exhibit a clicking sound. This may be due to the mirrors being manually folded in, during transportation, going through a car wash, bumped in a parking lot, or found during pre-delivery inspection (PDI). Prior to the replacement of any components, attempt to synchronize the mirrors by following the Power Mirrors Synchronization procedure. Refer to Workshop Manual (WSM) Section 501-09 Rear View Mirrors - General Procedures - Power Mirrors Synchronization.
SSM 508112022-06-01. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some 2020-2022 Explorer/Aviator vehicles may exhibit the A/C blowing warm air with DTCs P0645, P2CFC, and/or P2CFD present in the heating ventilation and air conditioning (HVAC) module. This may be due to spread terminal/terminal pushout in wire harness 14290 and on the corresponding pins to the body control module C (BCMC). Before replacement of the BCMC, disconnect all connectors from the BCMC and check the BCMC pins and wire terminals for damage. Refer to Workshop Manual (WSM), Section 419-10. If spread terminals or terminal pushout is present, repair as necessary. Refer to Wiring Diagram, Cell 005 for repair procedures. Reconnect all connections to the BCMC as indicated by the procedure in the WSM. Test the function of the A/C to verify that it is blowing cold air.
SSM 503792022-02-04. Service bulletin. VISIBILITY:SUN/MOON ROOF ASSEMBLY. Some 2011-2022 Explorer and 2020-2022 Aviator vehicles may experience an inoperative roof opening panel motor. If diagnostics lead to a motor replacement, visually inspect the original motor for signs of water intrusion. If found, determine source of water leak prior to replacing the motor. Refer to Workshop Manual (WSM), Section 501-17, Pinpoint Test A for 2011-2016 and Pinpoint Test B for 2017-2022 for identifying the source of the water leak.
SSM 500152021-09-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; VISIBILITY; EQUIPMENT. Some 2020-2021 Ford and Lincoln vehicles are equipped with an anti-fogging feature known as enhanced windshield anti fogging strategy (EWAFS). This feature automatically adjusts airflow in the cabin to prevent the windshield from fogging up and may be perceived by customers as irregular climate control functionality. To reduce fogging, the EWAFS functions include: the air condition (A/C) button may turn on and off automatically, recirculated air may turn off automatically in all air modes except MAX A/C, recirculated air may also turn on and off automatically in various airflow modes in order to improve heating or cooling efficiency, and in auto climate control, high humidity conditions may automatically engage A/C compressor, increase blower motor speed and/or direct more air to windshield. Continue to monitor the Workshop Manual (WSM) for EWAFS updates.
SSM 492702020-11-04. Service bulletin. VISIBILITY; EQUIPMENT. Some 2020 Aviator/Police Interceptor Utility vehicles built on 26-May-2020 and through 28-May-2020 may have been built with windshield washer fluid contaminated with brake fluid. If a vehicle exhibits a-pillar and/or rear liftgate trim or tail lamp appearance concerns, collect a sample of the washer fluid using a suction device and place in a white paper or Styrofoam cup. Washer fluid that appears green in color would indicate the washer fluid has been contaminated. Flush the washer fluid system and repair the affected windshield a-pillar area and liftgate area as necessary.
