NHTSA complaint #11711793

Owner complaint summary

Hello, on October 14th 2024 I reached out to Toyota over a “engine maintenance required” message on my dash along with a check engine light. I took it to the local toyota dealership in Downey CA. After testing the Engine coolant bypass valve B Control circuit high failed. Toyota replaced the valve on October 21st 2024. Issuing me a 1year/12,000 mile warranty. On Thursday January 15th 2026 the drive start control malfunction warning light along with a P26AE error code displayed. Upon testing the engine coolant bypass valve B control circuit high failed again. Speaking with Toyota my vehicle VIN is not part of the CSP service campaign they have for 19-23 Corolla models. I spoke with Toyota Corporate and they couldn’t/wouldn’t help. This is a severe safety risk as the valve failed at a moments notice with no warning or symptoms. Additionally it can lead to engine stall and catastrophic damage, risking other drivers if engine loses power. This is an ongoing and recurring issue with RAV4/Corolla/Cross models and Toyota is facing a lawsuit here in California from other drivers with the same problem. I would like for my VIN to be added to the safety recall as Toyota Knowingly replaced the Valve with the same defective part per the technician who fixed my vehicle the first time who warned me this was going to happen again. Thank you for your time and assistance in this matter.
