What 2026 Toyota RAV4 Plug-In Hybrid owners say
Transmission & drivetrain
The contact owns a 2026 Toyota RAV4 Plug-in Hybrid. The contact stated that while starting the vehicle, several unknown warning lights illuminated. The vehicle was towed to a dealer, where it was diagnosed with an EV inverter and transmission failure. The vehicle was pending repairs and remained at the dealer. The manufacturer was notified of the failure. The failure mileage was approximately 60.
On 7/7/2026, while driving on a local road at under 600 miles from purchase (590 on odometer), the dashboard displayed a warning that something was critically wrong and instructed the driver to pull over immediately. Once pulled over, the vehicle lost the ability to shift and became fully inoperable. Multiple alerts triggered simultaneously: Drive-Start Control System, AWD System, Check Engine, Integrated System Warning (TSS malfunction), and Hybrid System. The vehicle would not power on for 15-20 minutes, after which it powered on with some functionality restored (possibly an internal reboot), though alerts remained present. It came to rest partially obstructing a live traffic lane with no ability to move further off the road, creating a collision risk. Vehicle was flatbed towed to the dealership. Dealership held the vehicle one week (7/7-7/14). …

Driver assistance
When my wife left for work the car displayed an SRS/airbag warning on the dash. It was running so she decided to go to work, but turned around after a few miles when she realized all of the driver assist systems were also disabled. When she got home I checked the battery voltage and it read 11.8 volts (I also read the DTCs, and pulled B1AC0). After charging overnight the error was gone. This vehicle is driven almost daily, was delivered to us 3 months ago, and doesn't sit with the ignition on draining the battery (my short way of saying there no behavioral or maintenance related reasons for this to occur). I have been monitoring the battery charge after drives now and putting it on the charger every night. It appears the car is chronically undercharging the battery--a known issue going back several years on RAV4 hybrids (layperson analysis here: [redacted])
If I could select everything under the adaptive driver assistance details, I would. Upon startup, every warning light lit up on the car and messages popped that all of the safety systems were disabled on the car with a message to visit the dealer stating there was a "system malfunction." I turned the car off and turned it back on and all warnings remained and passenger airbags and other safety features remained disabled on the car.
