The heated steering wheel in my 2019 Toyota RAV4 Hybrid experienced a significant overheating incident that resulted in smoke, bubbling, and damage to the steering wheel's leather covering. Approximately 10 minutes after activating the heated steering wheel function, smoke began coming from the steering wheel. The material beneath the leather covering appeared to become excessively hot and began visibly bubbling and expanding. As the overheating continued, the leather covering ruptured, creating a hole in the steering wheel. Prior to this incident, the steering wheel was intact, with no punctures, holes, or visible damage. The hole developed during the overheating incident as the material beneath the leather bubbled and the covering ruptured. This occurred during normal use of the vehicle's factory-installed heated steering wheel feature. The sudden appearance of smoke and excessive heat created a serious safety concern, including the potential for burns, fire, driver distraction, and loss of vehicle control. The vehicle was subsequently taken to a Toyota dealership for inspection. The exact cause of the overheating has not been determined. I am reporting this incident because a heated steering wheel should not produce smoke, overheat to the point of damaging its exterior covering, or create a potential fire hazard during normal operation.

I am reporting a potentially recurring safety-related failure of the electric engine coolant/water pump on my 2019 Toyota RAV4 equipped with the 2.5L A25A-FKS engine. My vehicle recently developed DTC P26CB/P26CB71, indicating an electric engine coolant pump performance/speed problem. The failure caused loss of proper coolant circulation and resulted in my vehicle overheating while I was driving on the highway. An unexpected cooling-system failure at highway speed creates a safety hazard and can result in severe engine overheating, potentially catastrophic engine damage, and an unexpected need to stop near traffic. Approximately two months before this failure, my vehicle received a separate cooling-system repair from an authorized Toyota dealer under Customer Support Program 24TE04, which covers the flow shut-off valve/water-bypass assembly on certain 2019–2021 RAV4 vehicles. Approximately two months later, the vehicle developed the P26CB coolant-pump fault. Toyota previously documented electric water-pump problems involving P26CB71 on A25A-equipped vehicles. In Tech Tip T-TT-0614-20, dated May 28, 2020, Toyota identified P26CB71, P26CA14, and P26CA31 and/or coolant leakage from the electric water pump on A25A applications, including the RAV4. Toyota stated the issue was "currently under investigation." Toyota subsequently confirmed to me that the P26CB water-pump issue is separate from the 24TE04 repair and that there is currently no Customer Support Program or warranty extension covering the physical electric coolant pump on my 2019 RAV4. I request that the federal safety agency review complaint, warranty, repair, and manufacturer data to determine whether premature electric coolant-pump failures involving P26CB/P26CB71 represent a broader safety-related defect trend, particularly in 2019–2021 RAV4 vehicles equipped with the A25A engine, and whether further investigation or corrective action is warranted.

Component: Engine — Engine Cooling System — Coolant Pump Summary: The electric water pump on my 2019 Toyota RAV4 failed prematurely at 64273 miles. The check engine light illuminated with diagnostic trouble code P26CB (Engine Coolant Pump Performance/Stuck Off). The engine coolant temperature fluctuated rapidly / coolant level dropped. The vehicle required immediate repair to avoid engine damage. This is a recurring failure pattern on 2019–2021 Toyota RAV4 and Camry vehicles equipped with the 2.5L A25A-FKS engine, where the electric water pump seizes due to an apparent defect in its plastic housing and rotor assembly. Failures are routinely reported at 30,000–60,000 miles—far below the expected service life of the component. Loss of coolant circulation creates an overheating hazard and can lead to sudden loss of propulsion and engine damage while driving. Toyota has issued technical service bulletins related to coolant seepage at the pump but has not recalled the component or extended warranty coverage, leaving owners to bear repair costs of $600–$1,300 for a premature defect-driven failure. I request the federal safety agency to evaluate this defect for a safety recall.

The Coolant Bypass Valve on my vehicle failed, leading to a risk of sudden engine overheating and potential coolant leaks into the electrical harness. This is a documented defect (CSP 23TE03) that Toyota has failed to address for vehicles over 100,000 miles, creating a safety hazard for high-mileage owners. This is a major concern on a known issue and those that don't have funds to pay for this known failure. They need to do a recall for ALL!

A coolant leak from the flow shut‑off valve caused the engine maintenance warning light to remain on for an extended period. This issue is covered under Toyota Customer Support Program 24TE04. The warning light is a safety concern because it indicates an active engine‑related malfunction and can mask other warnings. The defect was first diagnosed by a Toyota dealership at approximately 97,000 miles, well within the CSP coverage window. The dealership stated the vehicle “did not meet criteria” and refused to perform the repair, even though the symptoms matched those described in the CSP. The issue continued until a second Toyota dealership later confirmed the same defect and replaced the coolant bypass valve. Because the vehicle had since exceeded 100,000 miles, Toyota refused to cover the repair under the CSP, despite the defect being documented earlier within the coverage period. Multiple attempts to resolve the issue with Toyota corporate have resulted in no returned calls or meaningful response. The defect caused prolonged operation with an illuminated engine warning light, which presents a safety risk and indicates a failure to properly address a known issue covered under Toyota’s Customer Support Program

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.

2019-2023 model year Toyota RAV4s and Toyota Corollas are equipped with defective coolant bypass valves prone to premature failure which can cause coolant to leak out of a vehicle’s closed-loop coolant system, harming its ability to properly regulate engine temperature. This can cause overheating, stalling, increased emissions, and total engine failure and also allows coolant to leak into and damage surrounding engine components, including a vehicle’s electrical system, the complaint relays. The warning message that common appears for this issue is "Engine maintenance required Visit your dealer "

The engine maintenance light came on and I took the car to my independent mechanic. The "soft code" indicates that the coolant system valve/hose (engine coolant bypass valve) is showing in the closed position when it should be open. My mechanic has tried to order a replacement part, but is having trouble finding one. After my personal research, I see that there is a Class Action Lawsuit regarding this part from 2024 indicating that it can cause the car to overheat, stall, and potentially severe engine damage. Toyota has no formal recalls on this, but it has been indicated that some owners have received support from Toyota on models built up to 2021.

I am submitting this complaint regarding a recurring issue in the coolant bypass valve of my 2019 Toyota RAV4 XLE Premium. Although there was no check engine light, the vehicle displayed a persistent warning: “Engine Maintenance Required – Visit Dealership.” This message repeatedly appears on the instrument cluster and blocks critical driving information, including the speedometer, fuel economy, and other key displays. Even when the driver manually cancels the message, it returns within minutes. This creates a constant distraction and obstructs visibility, which poses a safety risk during driving. I took the vehicle to the dealership, where they diagnosed the issue as an internal short circuit in the coolant bypass valve and retrieved diagnostic trouble code P268115. This code relates to a malfunction in the valve’s electrical control system, which affects the engine’s ability to regulate temperature effectively. Toyota currently offers a Customer Support Program (CSP) for the coolant bypass valve, but only if the valve is leaking coolant. However, my vehicle's failure was due to an electrical defect, and Toyota does not cover this under the same program. This creates an unfair burden on owners and fails to address the full scope of the issue, even though the results—loss of proper cooling function—are the same. Many RAV4 owners have reported similar problems online, but no recall or technical service bulletin has been issued for this kind of failure. I believe this defect raises genuine safety concerns, including: Driver distraction due to persistent warning messages Obstruction of critical dashboard information Potential for engine overheating or reduced performance I respectfully request that the federal safety agency investigate this issue as a potential safety-related defect and determine whether Toyota should be required to expand support or issue a recall for this component, regardless of whether the failure is due to coolant leakage or internal electrical malfunction.
