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.

"Engine Coolant Bypass Valve failed suddenly on highway (Code P2681-15), risking engine overheat and stall. Toyota acknowledged this defect under CSP 24TE04 but refused assistance due to vehicle having 103,660 miles (just past 100k miles). Failure causes immediate safety and overheating hazard."

Toyota made a defective coolant valve in their 2019-2021 cars that leaked spontaneously in these vehicles. Over 950,000 cars have been affected to date, including my 2020 Rav4. They are aware of the issue and made a customer support program for this issue which led to engines overheating/electrical code problems, which can cause a severe safety issue if left unrepaired. The program however has a limitation until November 2025 or 100,000 miles whichever comes first. When I was alerted of this, I brought my car to the dealer for service, but they wouldn't replace the part because it wasn't leaking too much at the time to need repair. However, just 4 months after the primary coverage expired, my engine code went off and when I brought my car, the coolant valve turned out to be defective and leaked into the electrical wire harness which then also had to be replaced in addition to the coolant valve. The repair cost was $1200 and both were required to keep the car driving safely and reliably on the road. Because my car had 120,000 miles and the known issue presented after Nov2025, Toyota refuses to cover the service, although it is a known manufacturing defect. Toyota is committing fraud to avoid covering this safety issue. The repair is expensive and if left unrepaired, the cars can spontaneously catch on fire on highways and in parks leading to wild fires and endanger others on the road. The toyota technician specifically informed me the issue was similar to other cars and known and the defect led to the destruction of the wire harness. To avoid a safety recall, Toyota reached a private settlement against class action lawsuit and created a limited CSP to avoid covering the defect in cars like mine to maintain their reliability status in consumer reports so cars like mine with little higher mileage won't be reported. It is fraud. I believe they are skipping on consumer repair bills that consumers on entitled to for their manufacturing defect.

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

The coolant bypass valve failed and the car is a 2021 Rav 4 LE. I called Toyota and according to the VIN it is not covered for this type of repair. I see quite a few cars have had this same issue, all Toyota's. It was inspected and repaired at a local Toyota Dealership but I had to pay out of pocket for the repair. There was a brief warning light that said "Engine Maintenance Required" See dealership or some such thing. Of course it's a safety issue if the coolant valve bypass failure causes the car to overheat.
