Summary
Toyota is issuing a safety recall for 30,978 units of the 2026 Toyota RAV4 Plug-In Hybrid due to an electronic control unit (ECU) software error that could cause the powertrain to lose power or shut down entirely at higher speeds. The safety recall, filed under NHTSA designation 26TA22, centers on a communication malfunction within the motor generator ECU. According to recall documentation, the software error occurs during the initialization sequence of the motor generator ECU under specific startup conditions.
When the RAV4 Plug-In Hybrid reaches higher highway speeds, the system requests a higher-speed control mode for the electric motor generators. If the ECU initialization fails at startup, that higher-speed control mode becomes unavailable.
For the rear motor generator, the failure forces the vehicle into a fail-safe limp-home mode, disabling rear-wheel drive and operating strictly in front-wheel drive at reduced speeds. However, because the front motor generator uses the same control program, a failure on the front motor at higher speeds can cause the entire plug-in hybrid system to shut down completely while in motion, increasing the risk of a crash.
Toyota launched an investigation after receiving a field technical report from Japan involving a vehicle that lost all-wheel drive and entered a reduced-speed fail-safe mode. Laboratory and vehicle drive testing conducted through August and September 2026 confirmed that software failure could trigger a total loss of motive power.
As of September 30, 2026, Toyota has identified 38 field technical reports and 58 warranty claims in the U.S. market related to the condition.
Toyota dealers will update the motor generator ECU software free of charge for all affected owners. Owner notification letters are scheduled to be mailed starting November 22, 2026.
