Toyota is recalling about 31,000 RAV4 plug-in hybrids that can lose power while driving

Toyota’s 2026 RAV4 Plug-in Hybrid has a computer that can switch the whole plug-in hybrid system off while the SUV is rolling. The company announced the recall on Oct. 7 from its Plano, Texas, headquarters, covering about 31,000 model-year 2026 RAV4 Plug-in Hybrids sold in the United States and no other model year.

The trouble sits in an electronic control unit, or ECU, that manages the plug-in hybrid system. A fault in that unit can shut the system down in motion, and the loss of drive power is most dangerous at higher speeds, where a driver has less room to react and traffic behind has less time to respond. Toyota names the added crash risk as the reason for the action, and the announcement reports that only the 2026 model year is involved.

ECU fault and software remedy

In its Oct. 7 announcement, Toyota describes the defect in a single sentence: a fault can occur in an ECU for the plug-in hybrid system. The company does not publish a root cause, a failure rate or the conditions that trigger the shutdown, and it describes no dashboard warning that precedes it. The only symptom it names is the plug-in hybrid system stopping while the vehicle is moving.

The remedy is a software update. Dealers will update the software in the affected ECU at no cost to owners, which points to a programming problem rather than a part that has to be replaced.

Owners will not hear about it right away. Toyota expects to notify them by early December 2026, which leaves roughly two months in which affected SUVs stay on the road with the fault unresolved. Toyota tells owners to enter a VIN or license plate at its recall lookup or on NHTSA’s recalls page to see whether a specific RAV4 is on the list, and notes that the list reflects the filing date and may change.

RAV4 Prime precedent from 2023

A drive-system shutdown is a failure mode Toyota has dealt with on this very nameplate. In February 2023, Toyota filed recall 23V-041 for 16,679 2021 RAV4 Primes, the earlier name for the plug-in. That defect lived in the hybrid vehicle control ECU, made by Denso: software miscalculated the hybrid battery’s output limits, so a rapid press of the accelerator after long stretches of cold-weather EV driving could drop battery voltage below a threshold and stop the hybrid system. The remedy then was also a software update, and owner letters went out between Feb. 27 and April 3, 2023. NHTSA’s report put the affected build window at Nov. 25, 2019 to June 24, 2021, and estimated that 100 percent of the vehicles in the population carried the defect.

The 2026 recall is a separate problem on a newer model year, and Toyota has not said the two share a cause. What they share is the consequence the company puts in writing: loss of motive power in traffic.

Battery-electric shutdowns earlier in 2026

Toyota’s electric vehicles have drawn similar action this year. A June 18 filing under recall 26V393 covered 20,991 vehicles: 11,495 Toyota bZ models, 4,757 Subaru Solterras and 4,739 Lexus RZ models. In that case a conflict in the battery ECU’s memory between two integrated circuits can trigger an “EV System Malfunction” warning and shut down the electric drive system, risking loss of motive power at speed. Toyota decided on that recall on June 12, six days before the filing.

In September, Toyota recalled 8,521 2026 C-HR battery-electric vehicles over a programming error in the battery ECU that can overcharge the battery during regenerative braking, again ending in a protective shutdown of the electric drive system while driving, AutoGuide reported. Letters for the C-HR recall are due to start on Oct. 18, which makes the RAV4 Plug-in Hybrid notice, by early December, the slowest of the three to reach owners.

The recall lands as Toyota is reporting steady volume. Toyota Motor North America’s third-quarter 2026 sales release, dated Oct. 1, put U.S. sales at 633,223 vehicles, up 0.6 percent, and quoted Andrew Gilleland, senior vice president of the Automotive Operations Group, saying the company is “well-positioned to finish the year strong.” A software recall of this size does not change that arithmetic by itself, but it adds a third drive-shutdown action to Toyota’s 2026 ledger within about four months.

Toyota’s release carries no NHTSA campaign number, so the federal report that normally lists the ECU part number, the production window and the date Toyota decided to act was not available in the materials the company published. The 31,000 figure is a U.S. count only, limited to the plug-in hybrid and not the regular RAV4 hybrid, and Toyota gives no figure for how many reports of shutdowns led to the recall.
