2026 Toyota RAV4 Plug-in Hybrid problems

“While driving in heavy traffic, the engine shuddered then dashboard warnings: "Hybrid System Malfunction Output Power Reduced, Drive-Start Control Malfunction, AWD System Malfunction." I pulled over, parked, then the transmission wouldn't shift to drive or reverse.”

“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.”

“On XXX, my wife, who is [XXX] pregnant, was driving our brand new 2026 Toyota RAV4 Plug-In Hybrid (approximately 20 miles on the odometer) at 45 mph on a highway when the vehicle experienced a sudden loss of propulsion. What failed: The hybrid powertrain system shut down while the vehicle was in motion. The instrument cluster displayed "Hybrid System Malfunction Do Not Tow This Vehicle" along with check engine light / a multitude of other warnings. The vehicle lost all propulsion and would not restart. The vehicle is available for inspection upon request and is currently at a Toyota dealership. Safety risk: The vehicle lost motive power in active traffic on a 45 mph roadway. My wife was forced to coast to the shoulder with traffic approaching from behind. Sudden loss of propulsion at highway speed created a substantial risk of a rear-end collision and serious injury to my pregnant wife and our unborn child. Reproduction/confirmation: The vehicle was flatbed towed by Toyota Roadside Assistance to an authorized Toyota dealership, where it is being diagnosed. Other inspections: A case has been opened with the Toyota Brand Engagement Center. Police and insurance…”

“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: [XXX])”

“A few weeks after purchasing a brand new Toyota Rav 4 we had three incidents of "ghost braking". The first was sometime between XXX and XXX. While traveling about about 35 MPH the car suddenly braked hard and the warning light came on.. No cars of objects were in the road on any side, Then on XXX, we were traveling onXXX in the far left lane heading south in [XXX]. We were traveling at 70 MPH with no cars in front of us and a semi slightly to the right and behind and a car in our lane behind us. The car suddenly braked hard and the warning light went on. Fortunately, my husband was able to steer into the shoulder to avoid a collision by the car behind us. We narrowly escaped. We called the dealership and, although they expressed concern, nothing was done. I called Toyota directly and was put in touch with an advocate. We took the car in twice and then the car was returned to us without resolution.Then on XXX, we were traveling east on [XXX] near [XXX] and the car again braked hard and the warning light came on. Again there was no car in front of us and the car behind us was far enough back to be able to brake. The car is now at the dealership awaiting a repair…”

“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). Technician confirmed alerts were genuine but could not reproduce the fault after ~38 miles of test driving. Only historical communication codes detected; no active diagnostic trouble codes (DTCs) present. Vehicle was returned with no repair and no identified cause. Unsure if dealer service center contacted Toyota…”
