Every figure in this 2020 Toyota Avalon factory service and repair manual is keyed to this exact model year, engine and trim, so the specifications and torque sequences you work to are the ones Toyota published for the 2.5L hybrid four (A25A-FXS) or the 3.5L V6 (2GR-FKS) in your car rather than a value carried over from an adjacent model year.

Known issues on the 2020 Avalon. Two recalls are on federal record for this model year. The first concerns the occupant classification sensor in the air bag system: an air bag that does not deploy during a crash increases the risk of injury. The second concerns the gasoline fuel pump, and if the fuel pump fails the engine can stall while driving, increasing the risk of a crash. Owners have filed 13 complaints for the year and Toyota has issued 172 technical service bulletins.
Whether you are tracing a stall back to the fuel delivery side, reading occupant classification sensor data, or working through a service interval on the hybrid drivetrain, the manual holds you to Toyota's own procedure and the right value for your specific 2020 Avalon.
