2019 Toyota RAV4: sudden loss of power

Filed Aug 23, 2026 · Driver assistance, Fuel system · CO

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.

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!

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)

My 2019 Toyota RAV4 experienced a dangerous electrical and transmission failure that ultimately caused the vehicle to stall while driving and made me lose control. For several weeks before the incident, the vehicle showed subtle hesitation when accelerating but no warning lights. After the car stalled and spun out coming off the Ben Franklin Bridge onto I-76 near downtown Camden, police responded, confirmed the vehicle had unexpectedly shut off, and verified there was no crash damage. I later brought the car to the Toyota dealership, where they discovered corrosion on the battery cable, failed ABS sensors, and a weak battery. I paid $668 for a new battery, new cable, and ABS sensor repairs. At that time, the dealership did not inform me of any transmission issues and released the vehicle back to me. I made it only a short distance up the road before realizing the vehicle could not accelerate past 40 mph and was still malfunctioning, so I immediately returned it. The next day, the dealership initially claimed there was nothing wrong with the vehicle, but after I insisted they re-evaluate the car, they then informed me that the transmission was failing and needed replacement. This sequence of electrical instability, combined with the transmission malfunction, ultimately led to the earlier stall where I lost all power steering and braking assist and spun out into the median. The vehicle, diagnostic records, and replaced components are available for inspection. The sudden loss of power and control created a major safety risk to me and other drivers in a high-traffic area.

My 2019 Toyota RAV4 Hybrid (VIN: [XXX] ) suffered sudden engine failure due to coolant intrusion. On Nov 20, 2025, Johnstons Toyota in Harriman, NY (RO#XXX) diagnosed the issue and recorded DTCs P26CA31 and P26CB, which indicate failure of the coolant flow control/bypass valve. The dealer confirmed heavy white smoke from the exhaust with a strong coolant smell and advised the engine had failed, recommending a replacement. This vehicle is part of the early 2019 Japan-built batch widely known for premature electric water pump and coolant-flow system failures. Internal impeller swelling, seal leakage, and bearing seizure can cause coolant pressure spikes and ultimately head-gasket failure with coolant entering the cylinders. This defect has been reported by thousands of RAV4 Hybrid owners (2019–2021). Toyota has addressed it quietly through internal TSBs such as XXX and XXX but no public recall has been issued. The safety risk is severe: the engine began emitting thick white smoke and ran roughly, risking sudden power loss, overheating, or engine seizure while driving. A stall at highway speed could easily cause a collision. Toyota USA opened Case #XXX but declined assistance despite the defect being well documented. This failure was sudden, with no warning lights prior to the incident. Given the widespread nature of this defect and its clear safety implications, I request that the federal safety agency open a formal investigation into the electric water pump/coolant system failures in 2019–2021 Toyota RAV4 Hybrids and consider requiring a safety recall.

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 2019 Toyota RAV4 Alternator failed at 43,000 miles. The vehicle has been repaired by Toyota Authorized Dealer and is unavailable to be inspected for the same issue. This issue occurred suddenly. My car flashed a charging alert, which I couldn't read because I was driving. Shortly afterward, my power steering on my vehicle went out, making it hard to steer and the car stalled in the middle of the road. When I placed my blinkers on, I was informed by another driver that they couldn't see my blinkers. If this had occurred on the highway, this could have been a more significant safety concern. The authorized dealer confirmed that the alternator failed—no other explanation of why it failed. The authorized dealer only inspected it. The issue appeared on May 10. The only warning provided was a charging alert. This appeared minutes before I lost power steering and the car stalled.

Engine stalled on a highway going 65 mph in cruise control. I had 1/4 full fuel tank. just before the engine stopped working I read information on my dashboard I have to stop the car in .5 miles, than .3 miles and engine stalled within seconds. I was able to pull over with dead engine. I shut down the car using key (I have a mechanical key for ignition) and car started with a message 'hybrid system malfunction. output power reduced . visit your dealer." I visited local mechanic who read the codes and instructed its a faulty fuel pump. I filled the car with more gas and drove couple of miles with reduced power. I left the car for 36 hours and it started to run ok by itself. dealer replaced fuel pump and now it works fine. The day of incident I was able to smell gas around engine bay before incident. I was able to smell strong gas smell after incident after I filled more gas in the vehicle most likely from engine bay fresh air intake. My assumption is this is due to bad fuel/air ratio and the result was unburned fuel. The week before the incident engine felt it kicked in roughly on its start up (my car is a hybrid). I had a fuel pump recall performed 4 months before but the fuel pump failed based on codes p319300 p008700 p107a2a . dealer replaced fuel pump (2nd time) and car works well and much smoother than before.
