Consumer Description

The Engine Coolant Bypass Valve Short in the vehicle has malfunctioned. This appears to be widespread issue not only in the Corolla, but in the Camry and RAV4, and appears to affect model years 2019-2024. This issue caused coolant leakage, has the potential to cause issues with the engine, and affects the A/C/Heating systems as well. There were no warning signs prior to the failure, and the car had just passed a multi point inspection 4 days prior to the failure. The problem has been reproduced by my local Toyota dealership.
