Consumer Description

Had my car (Toyota Corolla 2020 SE) give a “engine maintenance required, take to a dealer” error message on my digital dashboard. No error codes from any maintenance device but apparently only the Toyota dealership can find this in the software using their computers to find it somewhere deep in there… The problem is the upper engine coolant bypass valve. This is costing me almost $1000 including the $80+ in diagnostics that ONLY the Toyota dealership can see and find out. Apparently this is a very common occurrence with the 4 cylinder corollas and RAV4s.
