"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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The flow shut-off valve (coolant leak) failed. This exact component was later included in Toyota’s official recall. The defective part was diagnosed by a mobile mechanic and replaced at a licensed independent auto repair shop. The failed component itself is no longer available, but all receipts and repair documentation are available upon request. How was your safety or the safety of others put at risk? The failure of the flow shut-off valve caused a coolant leak that created a significant safety hazard, as it affected the vehicle’s performance and drivability. This posed a risk to both my safety and the safety of others on the road, which is why I had the repair completed immediately before the recall was issued. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was first diagnosed by a mobile mechanic and then confirmed by a reputable independent auto repair shop, who identified the flow shut-off valve coolant leak as the root cause. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No inspection was conducted by Toyota, police, or insurance representatives. However, Toyota later issued a recall for this same component, confirming it as a known safety defect. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The vehicle experienced noticeable performance issues prior to the failure, which prompted me to call a mechanic.

Engine maintenance message appeared on my dash. I took it to Big O's Tires and Service a car repair service provider. Upon connecting to the car and inspecting they told me it was a faulty possibly leaking engine coolant valve. The cost to repair is $916. This may cause the engine to overheat and possibly fail due to overheating. This can be very dangerous because it will happen if it does happen while driving which could cause an accident. I have not fixed the issue yet due to a lack of funds but will have to fix it as soon as a get paid because I drive my family in this car and cannot risk catastrophic engine failure. Please have Toyota recall this part as it is a very common failure amongst 2019-2023 Rav4s. A class action lawsuit is underway due to how often this issue arises. Thank you for your time.

We replaced the original battery on May 27, 2024. A few weeks later, on June 15, 2024, an "Engine Maintenance Required" message appeared on the display screen. A local mechanic diagnosed the code and stated that the oil level was low so we added one quarter of motor oil. We also called the dealership, which stated that this code generally indicates a coolant bypass valve malfunction. We topped off the coolant fluid but the "Engine Maintenance Required" message still appeared (we were not able to clear it). A few days later, we took the vehicle to another mechanic, who informed us that the coolant bypass valve was broken and needed to be replaced. Given the 95-degree temperatures, we felt that we had no choice but to replace the broken valve because we did not want the engine to overheat. So we paid $570.28 for the mechanic to replace the coolant bypass hose and valve. The mechanic stated that this issue should not occur in any vehicle with only 38,000 miles, which means the valve was likely defective to begin with. It is suspicious that this issue occurred about two weeks after we replaced the battery and about 2,000 miles after we surpassed the factory warranty. Please investigate!
