The 2021 Toyota RAV4 Prime runs a 2.5L four-cylinder hybrid (A25A-FXS) in a plug-in driveline, and every specification and tightening sequence here is Toyota's own for that exact year, engine and trim combination rather than a value carried over from an adjacent model year or a different RAV4 variant.

Known issues on the 2021 RAV4 Prime. Four recalls are on federal record for this model year. The first covers the electronic stability control module software, where driving with a deactivated stability control system increases the risk of a crash. The second covers the exterior headlights, where the headlight aiming caps may have been improperly closed; adjusting the horizontal headlight beam can increase glare. The third covers the DC/DC converter in the propulsion system, where a short circuit can cause the DC-DC converter to overheat, increasing the risk of a vehicle fire. The fourth covers the hybrid power control unit on vehicles driven in EV Mode during certain cold weather driving conditions, where an engine stall increases the risk of a crash. NHTSA lists 134 owner complaints for the year, and Toyota has issued 191 technical service bulletins for the vehicle. The factory diagnostic and repair procedure behind each of those systems is here.
Whether you are chasing a stability control fault, a cold-weather stall in EV Mode, or a headlight aim complaint on a service visit, the numbers you work to are the ones Toyota published for this 2021 RAV4 Prime.
