Consumer Description

The coolant bypass valve in some Toyota models has been malfunctioning recently and has become a common issue. Dealer confirmed that this was the issue per attached diagnostic report/invoice copy. Costs were >$800 to repair the issue for a <$100 part and 30 minutes of labor. The "Engine Maintenance Required" warning was visible in the display. Unsure as to the short or long-term effects of this malfunctioning part, but as it's related to the cooling system of the vehicle, it may trigger other more serious issues.
