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.

Sudden and complete failure of the water pump causing an explosion of the part. While traveling down the interstate, put lives in danger due to sudden jolt and rapid deceleration. Recently brought the vehicle in to correct recall on the engine coolant bypass valve. Issue with the bypass valve hastened the deterioration of the water pump to the point of failure. Told by mechanic that this is a known issue that just happens with Toyota’s. If this is a known issue, then it seems to me there should be another recall on the water pump. Plastic parts with highly corrosive liquids at high temps do not mix. Toyota needs to fix this costly issue.
