NHTSA Service Bulletin 10181929: 2020 Lincoln Aviator
Official manufacturer communication context for 2020 Lincoln 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 2020 Aviator vehicles equipped with adaptive steering may intermittently display an Adaptive Steering Fault message in the IPC and/or exhibit a steering wheel offset from the straight ahead position without any related diagnostic trouble codes (DTCs) stored. This may be caused by the software in the steering effort control module (SECM) and the steering angle sensor module (SASM). To correct the condition, reprogram the SECM and SASM using the latest level of the appropriate Ford diagnostic scan tool. For claiming, use causal part 3600 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
