“I have a faulty coolant bypass valve on my 2021 Toyota RAV4. Every time I turn on the air conditioning the service engine required comes up on my notifications a known recall problem for Toyota RAV4’s of this year”

“2021 Toyota RAV4 (gas model) has experienced a sudden, unexpected engine stall/shutdown on a public road. The incident occurred while shifting into Drive after backing up in reverse. The engine immediately died without any prior dashboard warning lights or mechanical symptoms. The information screen displayed a message stating "Put Car in Park" or "Shift into Park." The vehicle safely restarted immediately after shifting back into Park and pressing the ignition button. This intermittent stall has happened three times under the exact same directional shifting conditions over the last 1.5 years, creating a high-risk scenario for a rear-end collision in active traffic. After previous incident (one year ago) when the engine stopped when shifting from reverse to drive, I took it to Toyota service. Dealership diagnostics could not previously replicate the issue due to its intermittent nature and the absence of a permanent check engine code. checked battery and performed health check.”

“My 2021 Toyota RAV4 began experiencing intermittent shuddering and vibration at low speeds around May 2026. The condition occurred while accelerating from a stop or at slow speeds and became more frequent over time. Because the problem was intermittent, the dealership was initially unable to duplicate it. Independent inspection later found dark transmission fluid containing metal debris, indicating internal transmission failure. I was informed the transmission requires replacement or rebuild. My vehicle has approximately 94,000 miles, which is well below the expected service life of a modern transmission. The symptoms are consistent with numerous reported complaints involving Toyota’s UA80 automatic transmission and torque converter. An unexpected loss of smooth power delivery or hesitation during acceleration creates a potential safety risk, particularly when entering traffic or crossing intersections. I am submitting this complaint so NHTSA can investigate as this is a very dangerous and concearning issue.”

“The contact owns a 2021 Toyota Rav4. The contact stated that while driving at approximately 30 MPH, the vehicle aggressively accelerated while the accelerator pedal was depressed. No warning light was illuminated. The vehicle was taken to a local dealer and remained with the dealer for additional diagnostic tests. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.”

““Required Engine Maintenance- Visit Your Dealer” message came on the dash. After doing some research and troubleshooting; it appeared to be the coolant bypass valve that everyone has had issues with. The problem was then confirmed with a local provider who instructed us to contact the dealer to see if they’d cover the repair. Otherwise the repair by them would be $700. Toyota customer service told us that there is no TSB or Recall for this issue. We would need to have the issue diagnosed and then pay out of pocket for the repair. This is an issue that spreads throughout so many vehicles that it needs to be a recall.”
