Toyota RAV4 slipping problems

Filed Aug 18, 2026 · Transmission · PA

**VEHICLE:** 2020 Toyota RAV4 LE **VIN:** [XXX] **CURRENT MILEAGE:** 126,776 miles **PURCHASE DATE:** October 2020 **COMPONENT:** Automatic Transmission (Power Train) **PROBLEM DESCRIPTION:** On XXX, I took my 2020 Toyota RAV4 LE to a transmission specialty shop (TJ'S Transmission Service Inc., Bedford, PA) because the automatic transmission was slipping while driving. The professional diagnosis (Invoice #XXX) confirmed the following stored fault codes: P2681, P2816, P08BA, P2713 The technician also confirmed that the transmission fluid was black and contained metal debris, indicating significant internal wear of clutch/band components. While researching these codes, I found that Toyota previously issued Technical Service Bulletin (TSB) T-SB-0160-18, titled "Transaxle Whine Noise, Harsh Shift, MIL ON, or Reduced Power," which acknowledges these SAME fault codes (P2816, P08BA, P2713, among others) as a known problem in the 8-speed automatic transmission (UA80/UB80 family, manufactured by Aisin). This TSB was officially issued only for the 2017-2018 Highlander and Sienna models, but the 2019 and later RAV4 uses the same transmission family (UB80E/UB80F) for the 2.5L engine, suggesting this is the same design or manufacturing defect that has not been officially acknowledged for this model. This issue represents a safety risk, as unexpected loss of power or transmission slippage while driving (for example, when merging onto a highway or passing) can create a dangerous situation for the driver and other vehicles on the road. I am requesting that the federal safety agency investigate whether a similar failure pattern exists in other 2019-2021 RAV4 vehicles equipped with this transmission, and that consideration be given to whether Toyota should extend coverage of TSB T-SB-0160-18 (or issue a specific one) to include the RAV4. No repair was performed at this time due to the high estimated cost without warranty coverage. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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)

The 2023 Toyota RAV4 8-speed transmission is catastrophically defective and poses an immediate safety hazard. It exhibits severe hesitation, slipping, and lurching when accelerating from a stop or low speed, and when attempting to merge into high-speed traffic (I-15/Las Vegas), creating a high risk of rear-end collisions. During these events, the RPMs spike and fall rapidly but the vehicle fails to accelerate. Furthermore, the vehicle lunges forward while the brakes are applied. The engine actively fights the braking system, requiring extreme physical force to stop the car and prevent front-end collisions. This lunging has repeatedly triggered the Pre-Collision System, causing the seatbelts to lock and tension against the driver’s body. Additionally, the vehicle exhibits steering resistance and feedback during turns, making it difficult to maneuver safely. The local dealership (AutoNation Toyota Las Vegas) inspected the vehicle and claimed these life-threatening behaviors are "normal" for this model.

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.

The vehicle several occasions been unresponsive to accelerate. This has happened on two separate occasions (days) in which the vehicle would not accelerate. The first occurrence was right after I purchased the car and drove it the first full day I owned it in September 2023. The second time was on Saturday December 16, 2023. When the vehicle is driven under 40 mph such as slowing for a turn, braking for a traffic light, picking up speed to enter onto a highway this problem occurs. It is when the gas is pressed down to accelerate, the vehicle does not respond by increasing the speed. The RPM's would go really high and the vehicle would receive the gas but would not "shift" and felt stuck. And the transmission was very loud. It felt like the vehicle transmission was slipping or not engaging/shifting. Adding more gas was not beneficial. The gas pedal could be pressed down to the floor and the vehicle was not responsive by shifting "gears" or picking up speed. The vehicle would not accelerate above 20 mph and the RPMs would go up. No lights or warnings were produced. The only way to get the vehicle to act normally once again was to pull the car over into a safe location, shift the car into park, shut the car off, wait for a few seconds, restart the car and proceed. In one session (driving the same day) the car repeated the inability to accelerate each time the vehicle was slowed down below 40 mph to come to a stop at a stop sign, take a turn, stop at a traffic light etc. This was dangerous as I was not able to proceed in traffic and caused other drivers to honk their horns at me, and left me stuck in intersections. This was very disconcerting and left me feeling endangered by not being able to follow the flow of traffic. Toyota Service did a diagnostic test on it twice now. The first time had torque converter codes. This 2nd time they claim there were no codes on the diagnostic test. They dropped the transmission pan and found no metal shavings.

While in transit I observed my rav4 engine light 4wd light and traction control light all come on and truck kinda felt like gear slip weather was clear. I continued and went across a railroad track and all of sudden truck completely shuts down and started smoking. I i coasted to side of road had it towed to my designated location Thought was on fire. After inspection following day it showed top radiator hose coupling broke causing antifreeze to spew from radiator ... I replaced the hose thinking all would be repaired. Antifreeze and water was replaced And tried to crank it sputtered and wouldn't start . Now it still won't start. It has only 135k miles on it and I know it should be more

I left to go to work, and the transmission would not engage. I pulled out of the garage, the engine was revving but the car just slowly rolled. I thought it would warm up, but it did not. I was in the street, and I was able to slowly rev and roll the car back into the garage. It was very frightening and dangerous. My husband drove the car, the transmission worked, but sometimes it is still slipping. I'm afraid to drive it. It is only 8 years old and has 126k miles and we maintain it very well. I am so disappointed, we have been driving Toyotas for over 30 years, never had a big problem like this.
