2019 Toyota RAV4: transmission slipping

Filed May 9, 2026 · Transmission · NC

My 2019 Toyota RAV4 Adventure suffered a sudden catastrophic transmission failure while driving on the highway on April 28, 2026, resulting in loss of forward gears and a dangerous situation. On April 28, 2026, while traveling in [XXX] , my 2019 Toyota RAV4 Adventure (159,173 miles) experienced a sudden transmission failure with no prior warning symptoms. The vehicle began slipping, made a whining noise, would not properly upshift or hold speed (became stuck in 3rd gear), and eventually lost all forward propulsion, creating a safety hazard on the road. I had the vehicle towed to Zanesville Toyota in [XXX] . Their diagnosis (copy of repair order attached) revealed severe internal damage including: Torque converter clutch actuator stuck off Multiple pressure control solenoids stuck Transmission slipping and complete loss of all forward gears Fluid full but contaminated with metal debris and clutch material Whining noise The dealer quoted approximately $15,000 for a full transmission + torque converter replacement and denied goodwill assistance. This appears to be part of a known issue with the 8-speed automatic transmission (UB80) in 2019+ Toyota RAV4 models. I am concerned this is a safety defect that can cause sudden loss of power while driving, increasing the risk of a crash. I have attached the Zanesville Toyota repair order dated 04/30/2026 documenting the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Safety issue: The vehicle experiences intermittent loss of acceleration and transmission “slip/rev” events, especially when cold, from a stop, or at low speed. At times, the vehicle revs as if in neutral, then re-engages. The driver sometimes must press the accelerator fully to gain speed. In one instance, the vehicle was driven slowly for several miles, pulled over, shut off, restarted, and the function temporarily improved. When it started: Symptoms began immediately after a routine service visit at a Toyota dealership ([XXX]). First noted deceleration going uphill with recovery. Next day, multiple warning indicators/messages appeared and vehicle was towed to the same dealership. Dealer response: Dealership advised transmission replacement based on diagnostic codes and quoted approximately $10,000, stating fluid check was not necessary. Second opinion: Independent shop found transmission fluid level extremely low (reported approx. 1/4 full). They refilled fluid; initially vehicle drove normally, but intermittent slipping/revving continued after pickup (worse when cold/low speed). No external leaks observed by second shop at that time. Current status: Vehicle continues to show intermittent loss of acceleration/slipping behavior, creating a safety risk in traffic. No current check engine light, but symptoms persist. Codes/records available: Codes: P07457F, P28167F, P088A7F, P27137F, C137BA2, C1241, C1280, U1117, B2227. Location: New York.

The vehicle began displaying intermittent warning messages and slipping into "Mud & Sand" mode without cause. Later, multiple dash lights illuminated, including 4WD malfunction, check engine, and coolant system warnings. The vehicle became undrivable due to overheating. Dealership diagnostics indicated a failure in the coolant bypass valve actuator the electronic water pump was receiving a signal but not responding, resulting in loss of coolant circulation and overheating. There may also be a shorted control panel causing related system failures. This problem has been confirmed by a Toyota dealer, and the vehicle remains at the service center pending resolution. The issue appears related to a known Customer Support Program (CSP 24TE04), which covers the coolant bypass valve actuator. There was no prior accident or abuse of the vehicle, and the vehicle only has 52,000 miles. Safety was compromised due to unexpected power loss and overheating while in motion. The issue has not yet been resolved. The vehicle has also experienced prior water intrusion through the roof rails, which may have contributed to electrical damage.

I have a 2019 all-wheel-drive limited and for the last two months it has been slipping into mud and sand mode. It happens when I shift from driving to park or drive to park, and if I’m standing idle it will slip into mud and sand mode and switch off a few minutes later. Dealership says it’s the sensors but I had my sensors checked and there is no issue there.

Car doest not move right away at a stop even when stepping on the accelerator at 3-4 RPM. Very dangerous when your in the intersection when turning left or when crossing the street. Seems like the transmission slips
