Consumer Description

In the past week at 30,700 miles, my 2020 Toyota Corolla "Engine Maintenance light; see dealer" service light appeared on the dash. Through talking with a Toyota dealer, they are aware of this issue with Corollas, Camrys, and Rav4's. It is an engine coolant bypass valve, and appears to be faulty in many vehicles according to youtube videos, google, and Toyota service. Perhaps this needs to be a recall? Also, the dealer wants almost $800 to repair even though many people do it on youtube in under an hour. Parts are less than $200, and 1.5 hours of labor do not add up to $800.
