Consumer Description

There was a maintenance required notice on my dashboard and I searched up that it was my coolant bypass valve having an issue. Apparently it’s a defective part in Toyota Corolla and rav4 models from 2019-2023 I believe. The notice would come on and off each time I would start the vehicle. The dealership has confirmed this issue is common and after having it inspected and diagnosed, it was indeed the coolant bypass valve. My safety and the safety of others were fine, my engine would’ve been the unfortunate casualty if I did not take care of this.
