While driving on the highway, the vehicle suffered a sudden loss of engine power and went into a low-power/vapor lock state due to severe fuel starvation. This created a major safety hazard by stranding the vehicle on the highway shoulder and exposing occupants to high-speed traffic. Prior to the power loss, there were no advance warning lights until the engine stalled. A diagnostic scan performed immediately following the incident confirmed code P0087 (Fuel Rail/System Pressure - Too Low), along with cylinder misfire codes P030027 and P030100. To allow the vehicle to safely limp home from a remote location, an independent technician cleared the diagnostic trouble codes. An independent scan tool report clearly documented and confirmed the low fuel pressure fault prior to code clearance. The dealership subsequently declined to perform a warranty or recall fuel pump replacement citing the absence of active codes upon arrival, despite receiving the timestamped diagnostic report of the failure. The component has not been inspected by the manufacturer beyond the dealership's initial turn-away, but the vehicle and diagnostic documentation remain available for inspection upon request.

While driving in the mountains on a hot day, the car suddenly reported numerous faults, including check engine, parking brake malfunction, pre-collision system malfunction, AWD system malfunction, and secondary collision brake system malfunction. The car lost power and forced us to pull over on the side of a dangerous mountain highway. We powered-off the car for a few minutes and started it again and were able to proceed to our nearby remote mountain destination without another loss of power, but the faults remained. The next day we were able to get the car to a nearby NAPA store to read the check engine codes, which there were only 2 of the "P0087" code. I had them clear the fault codes in order to be able to safely drive the car (~120 miles) back home. Some quick research shows a known issue and TSB for that in our exact high-altitude and high-temperature situation - Toyota T-SB-0058-22, related to a known design flaw with the ECM and fuel suction tube. Luckily, it did not throw the errors again during our drive home. I made an appointment at our local AutoNation Toyota Arapahoe for the following week. I detailed the issue and provided pictures of the errors - including the code reader display. The dealer claimed to not find any issues and refused to address/execute the TSB, stating that the code must be active and present in order for them to fix it and that my pictures were not sufficient proof. I explained that it was an unacceptable safety risk to have left the car in that state and that the issue is known to only occur in certain conditions (e.g. high-altitude, high-temperature mountain driving). Issue remains un-addressed, which is highly unacceptable and poses a serious on-going safety risk.

We were driving down the highway passing another vehicle when we lost steering and the dash said "Steering Power Loss". We pulled to the side of the road where the vehicle stalled and would not restart. Probably 10-15 minutes later the vehicle started and we eventually made it to our destination. It was quite scary trying to get to the side of the road, in heavy traffic, and pulling over where there really was no shoulder, and not knowing whether the car would eventually restart or what. Although 2019 Toyota Rav4's have been recalled for this very issue, for some reason our VIN is not listed.

**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)

On July 31, 2026, while traveling approximately 55 mph on a Maryland highway, my 2025 Toyota RAV4 unexpectedly lost power and shut off while in motion. There was no check-engine warning before the failure. The vehicle became disabled in a travel lane. Police responded, and the lane had to be closed because the vehicle could not be safely moved. There was no crash, fire, or injury. The vehicle was taken to an authorized Toyota dealership. The dealer documented that it had “shut off mid drive,” reported finding no codes in the engine ECU, and performed service campaign 26TC03 concerning an incorrect mass airflow sensor reading. The dealer replaced a radiator air guide and stated that the vehicle should return for further diagnosis if it stalled again. On August 2, only approximately 36 miles after that service, the vehicle failed to restart at approximately 40,529 miles and required a jump. LTA and pre-collision system malfunction warnings appeared. The pre-collision warning returned while the vehicle was moving, and the Toyota connected app also recorded the malfunction. The vehicle was then towed back to the dealership and is available for inspection. The cause remains unknown. The concern involves an intermittent engine shutdown/no-start condition, a possible 12-volt electrical or charging-system failure, and the loss of forward-collision and lane-assistance functions. The dealer’s prior multipoint inspection marked the battery as acceptable, but no actual CCA battery-test result was documented.

While driving the 2019 Toyota RAV4, I found that the steering wheel was getting hard to turn and the car kept making grinding sound when turning. Due to I was short on time, I asked an old mechanic friend to check the RAV4 out before my road trip. He was unable to get the vehicle back; therefore, I used my other vehicle. While I was out of town the Mechanic contacted me, and ask if the car had been in water and I replied no. He suggested that I might want to see if there’s a recall. I googled recall for RAV4 vehicles and found that a recall had been issued for certain groups of power, steering boxes. This may allow water to enter the box that could corrode and cause loss of power steering that could cause an accidents. I’ve reached out to several Toyota representatives with this issue, but have been unsuccessful and getting them to see that this car may have been overlooked.

Rav4 2019 - We lost engine power while driving on the highway at 75 mph. We were in the #2 lane and were fortunate to be able to coast to the side of the road. Quite scary as there were semi trucks behind us.We had been driving for approximately 3.5 hours on the highway at 70-75 MPH. The outside temperature registering on our vehicle began at 110 and continued to increase on up to 118 degrees at the time of the incident. When we lost engine power, the following errors began flashing on the dashboard: PKSB Malfunction, Pre Collision System Malfunction, Secondary Collision Brake System Malfunction. We cleaned the sensors, turned the car off for 5 minutes and then turned it back on. Same warnings appeared. Got towed to the Toyota dealership. Next day all malfunction warnings gone. Car was behaving normally. Toyota service team was unable to reproduce the problem. They inspected the electrical, battery, sensors, etc. but could not find anything. Ultimately the service lead stated that the intense heat could have caused sensor malfunction. Scary!! We fortunate!
