Toyota, Lexus and Subaru are jointly recalling 20,991 electric SUVs built on their shared battery-electric platform after determining a faulty control unit can cause the vehicles to suddenly lose propulsion power with no warning, according to the recall filed with NHTSA under campaign number 26V393.

The three brands built the bZ, RZ and Solterra together on a co-developed platform, sharing everything from the battery pack to the electronic control unit that manages it, which is exactly why one software-adjacent defect could ground vehicles wearing three different badges at once. NHTSA’s filing describes the problem as a malfunctioning electronic control unit governing the high-voltage battery that can trigger a loss of drive power while the vehicle is in motion. Toyota told regulators it expects 100% of the recalled vehicles to actually have the defect, an unusually blunt admission that this isn’t a rare edge case.

What’s Affected

• 2026 Toyota bZ (11,495 units)
• 2026 Lexus RZ (4,739 units)
• 2026 Subaru Solterra (4,757 units)
• Total: 20,991 vehicles across all three brands in the U.S.

Losing motive power without warning is a different animal from a warning light failing to illuminate. A driver merging onto a freeway or crossing a busy intersection who suddenly has no forward thrust is at the mercy of whatever traffic is around them, which is why NHTSA treats sudden propulsion loss as one of its more urgent defect categories regardless of how few vehicles are involved.

Key Points

• The fix is a free battery ECU software update performed at any Toyota, Lexus, or Subaru dealership.
• Owner notification letters were mailed starting August 3, 2026.
• The defect affects all three platform-mates equally since they share the same underlying battery control hardware and software.
• Owners can also reach NHTSA’s own Vehicle Safety Hotline at 1-888-327-4236 to confirm a recall is on file for their specific VIN.

A joint recall spanning three separate brands is unusual outside of platform-sharing partnerships like this one, and it highlights a tradeoff automakers accept when they co-develop a vehicle architecture to cut costs: a defect discovered in one badge’s software almost always turns out to live in all three.

What Owners Should Do

• Check your VIN through NHTSA’s recall database regardless of which of the three brands you drive.
• Contact your dealer to schedule the free software update if you haven’t already received or acted on a notification letter.
• Toyota customer service can be reached at 1-800-331-4331; Subaru and Lexus owners should use their respective brand hotlines for scheduling.

The recall lands months before Toyota’s separate software fix for the C-HR electric crossover’s battery-overcharging defect, and together the two campaigns illustrate how much of an EV’s safety now rides on a single control unit’s code doing its job correctly every single time it’s asked to.
