NHTSA complaint #11737879

Owner complaint summary

The check engine light illuminated on my 2020 Toyota Camry XSE 2.5L with approximately 132,798 miles. An OBD2 scan revealed fault code P26AE — Engine Coolant Bypass Valve 'B' Control Circuit High. This is a known widespread defect affecting 2018-2022 Toyota Camry, RAV4, and Corolla vehicles equipped with the 2.5L Dynamic Force engine. The plastic valve casing is prone to cracking, allowing coolant to seep into the electrical connector and corrode the pins, triggering the fault. Toyota has acknowledged this issue through a Customer Support Program offering free replacement on qualifying vehicles, however many owners are still being quoted $900-$1,300 at dealerships. The faulty valve affects the engine coolant flow control system and transmission cooling circuit. Warning light appeared suddenly after a routine fuel fill. Vehicle has not yet been inspected by dealer. Component is available for inspection upon request."
