2023 Toyota Highlander Service and Repair Manual
Fitment is the whole point on a 2023 Highlander, where the hybrid 2.5L four (A25A-FXS) and the turbocharged 2.4L (T24A-FTS) share a badge and little else: this factory service and repair manual is tied to this exact year, engine and trim, so the specifications and procedures it gives are the ones Toyota released for the vehicle in your driveway rather than a value carried over from an adjacent model year.

Known issues on the 2023 Highlander. Five recalls are on federal record for this vehicle. Two of them came from Toyota distributors and concern tires. Southeast Toyota Distributors, LLC recalled certain 2021-2024 Highlander vehicles whose 20-inch accessory tires have an insufficient load rating for the vehicle's Gross Axle Weight Rating; tires with an insufficient load rating can be overloaded and fail, increasing the risk of a crash. Gulf States Toyota, Inc. recalled certain 2022-2024 model year Highlander L and Highlander LE vehicles equipped with the Blackout Package that includes 20-inch black alloy wheels and tires, where tires with an insufficient load rating may be overloaded and fail, increasing the risk of a crash. A third recall covers the steering column, where a deactivated driver's air bag that does not deploy as intended increases the risk of injury. A fourth covers the back-over prevention display function on vehicles equipped with a Panoramic View Monitor system, where a rearview camera that fails to display an image can reduce the driver's view behind the vehicle. The fifth covers the instrument cluster and panel, where an instrument panel display that does not show critical information can increase the risk of a crash. Owners have registered 210 complaints against this model year, and 129 technical service bulletins have been issued for it.
Whether the job is a camera feed or cluster display that goes dark, a load-rating question on the 20-inch wheels, or routine service on the hybrid 2.5L, the figures you work to are the ones Toyota specified for this 2023 Highlander.
