Consumer Description

Engine maintenance light came on after turning on air conditioner. Vehicle information: warning light came on at 56,800 miles on 2020 Toyota Corolla, no after market modifications to vehicle. I took vehicle to Toyota dealership for diagnostic testing. Conclusion: coolant bypass valve faulty causing leaks (this can cause overheating, stalling, increased emissions, and total engine failure and also allows coolant to leak into and damage surrounding engine components, including a vehicle's electrical system, the complaint relays). Fortunately, I PURCHASED AN EXTENDED WARRANTY when I bought the vehicle new, which covered the repairs. The faulty coolant bypass valve was replaced at the Toyota dealership. Had I not purchased the extended warranty, I would of been out of pocket for said repairs.
