Official manufacturer communication context for 2007, 2018, 2019, 2020, 2021 Ford Aviator, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Some 2018-2021 vehicles supported by FDRS may not list a software update for a module under the SW Updates tab although an SSM or TSB is published for a software update. This may be due to the module already being at the latest software level. A later software level may have been programmed at the assembly plant, during a previous dealer visit or by an over the air (OTA) update for vehicles that have automatic updates enabled in the SYNC system settings. To review a vehicle's OTA update history, visit the Connected Vehicle > OTA Dashboard tab in OASIS. Information about the OTA Dashboard can be found on FMCDealer.com when performing a search on OTA History Job Aid.

Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
