NHTSA Complaint #11700834 — 2019 TOYOTA RAV4

My 2019 Toyota RAV4 Hybrid (VIN: [XXX] ) suffered sudden engine failure due to coolant intrusion. On Nov 20, 2025, Johnstons Toyota in Harriman, NY (RO#XXX) diagnosed the issue and recorded DTCs P26CA31 and P26CB, which indicate failure of the coolant flow control/bypass valve. The dealer confirmed heavy white smoke from the exhaust with a strong coolant smell and advised the engine had failed, recommending a replacement. This vehicle is part of the early 2019 Japan-built batch widely known for premature electric water pump and coolant-flow system failures. Internal impeller swelling, seal leakage, and bearing seizure can cause coolant pressure spikes and ultimately head-gasket failure with coolant entering the cylinders. This defect has been reported by thousands of RAV4 Hybrid owners (2019–2021). Toyota has addressed it quietly through internal TSBs such as XXX and XXX but no public recall has been issued. The safety risk is severe: the engine began emitting thick white smoke and ran roughly, risking sudden power loss, overheating, or engine seizure while driving. A stall at highway speed could easily cause a collision. Toyota USA opened Case #XXX but declined assistance despite the defect being well documented. This failure was sudden, with no warning lights prior to the incident. Given the widespread nature of this defect and its clear safety implications, I request that NHTSA open a formal investigation into the electric water pump/coolant system failures in 2019–2021 Toyota RAV4 Hybrids and consider requiring a safety recall.
