What's wrong?
The battery ECU in these 2026 Rz, Bz, and Solterra electric vehicles is the computer that manages the high voltage battery. It watches battery conditions and tells the electric drive system when power is available. That control has to stay coordinated with the battery monitoring chip so the vehicle keeps propulsion power.
On affected vehicles, two chips in the battery ECU use overlapping memory address locations. During an operational check, the monitoring chip can overwrite data the battery control chip needs. When CPU load rises, such as during a low state of charge, that memory conflict can keep repeating until the electric drive system shuts down. Power steering and braking remain operational, but drive power is lost.
Before the shutdown, the vehicle displays an 'EV System Malfunction' warning message. Multiple malfunction indicator lamps for different systems also illuminate.
Who's affected?
Covers three 2026 electric crossovers, all tied to the same Battery ECU in the electric propulsion system.
| 2026 Lexus Rz | electric propulsion system |
|---|---|
| 2026 Toyota Bz | electric propulsion system |
| 2026 Subaru Solterra | electric propulsion system |
| Units affected | 20,991 |
| Field incidents | NHTSA has logged 1 field incident to date. |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific crossover is included.
What's the safety risk?
Unexpected loss of drive power increases the risk of a crash. If the "EV System Malfunction" warning appears or several system warning lamps come on, drive cautiously, avoid high-speed trips, and schedule the repair soon. Repair is free at any franchised Lexus dealer.
What should I do?
- Check your VIN to confirm your 2026 Rz, Bz, or Solterra is included in this recall.
- Contact a franchised Lexus dealer to schedule the free battery ECU software update that fixes the loss-of-drive-power fault.
- Bring the recall notice if one arrives. If not, reference recall number 26V393 when you call.
- Drive with extra caution until the software update is complete, since the vehicle can lose drive power unexpectedly.
What happens at the repair
At the dealer, a Lexus technician updates the battery ECU software that controls the high-voltage battery. The software update and labor are free under the recall. If you've already paid to have this condition repaired before the campaign, the owner letter instructs you to seek reimbursement under Toyota's General Reimbursement Plan. Keep your repair invoice and payment records so the service desk or Lexus customer service can route the claim.
