Consumer Description
At around 36,500 miles, my Toyota Corolla began experiencing issues with the coolant bypass valve, leading to engine overheating. This malfunction has significantly impacted my ability to drive safely, as the vehicle displays a notification every five seconds, obstructing my view of the digital speedometer and making it difficult to accurately monitor my speed. The issue was not indicated by a check engine light but a persistent "Engine Maintenance Required" message. This defect poses a serious safety risk, and there's a potential class-action lawsuit in progress regarding this very issue, suggesting Toyota might have known about the defect but failed to disclose it. The faulty component is not available for inspection upon request. As more people began to experience similar circumstances, it could lead to fatalities. Other participants to the forums says the issues start when their covered warranty expires. Within these forums there's a inconstancy of service centers honoring fixes, with no cost, knowing that there is an issue. I took the car to both a third-party mechanic and an authorized dealership, and both confirmed the problem. I was quoted $732.85 for the parts and labor within my area. I also called Toyota Global which I was told "a low mileage car shouldn't be having this issue", however, there are countless of forums saying otherwise. **Toyota Models Affected** 2019 Toyota RAV4 2020 Toyota RAV4 2021 Toyota RAV4 2022 Toyota RAV4 2023 Toyota RAV4 2019 Toyota Corolla 2020 Toyota Corolla 2021 Toyota Corolla 2022 Toyota Corolla 2023 Toyota Corolla [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
