Toyota Recalls 21,000 EVs Over Sudden Loss of Drive Power Risk
Software defects in 2026 Toyota, Lexus, and Subaru models could cause electric drive systems to shut down.
Toyota is recalling approximately 21,000 battery electric vehicles across its Toyota, Lexus, and Subaru brands due to a software defect that can cause a sudden loss of propulsion. The recall affects 2026 models, posing a significant safety risk if the drive system shuts down while the vehicle is in motion.
According to data from the National Highway Traffic Safety Administration (NHTSA), the recall involves 20,991 vehicles in total. The breakdown includes 11,495 Toyota bZ units, 4,757 Subaru Solterra vehicles, and 4,739 Lexus RZ models. The defect resides in the battery electronic control unit (ECU), which can trigger a shutdown of the electric drive system. While steering and braking functions remain operational during such an event, the NHTSA warned that "an unexpected loss of drive power increases the risk of a crash."
Technical Scope and Context
The recall is specific to the refreshed 2026 model year vehicles featuring the e-TNGA platform and North American Charging Standard (NACS) ports. This particular software issue does not extend to earlier versions of the bZ4X or Solterra that utilized the previous 71.4-kWh battery packs. The problem is isolated to the supplier software used in the battery ECUs of these newer configurations.
Industry Implications
For the EV market, a sudden loss of propulsion at highway speeds represents a critical safety hazard, as it can leave a driver stranded in active traffic. Although the vehicles are designed to provide warnings—such as an "EV System Malfunction" message—the potential for a high-speed stall makes the resolution of this software bug a priority for manufacturer reliability and consumer trust in the e-TNGA platform. This incident highlights the ongoing challenges of integrating new charging standards and software architectures across multi-brand platforms.
Next Steps for Owners
Toyota and its partners are offering a free software update to the battery ECU, which must be performed by authorized dealers. Owners can track the recall through NHTSA Campaign ID 26V393000. For those tracking specific manufacturer filings, the recall is listed under Toyota numbers 26LA07 and 26TA11, and Subaru number WRG26. Owners are encouraged to contact their local dealership to schedule the update immediately to mitigate the risk of power loss. Prompt action is essential to ensure the vehicle's propulsion system remains stable during operation.
