The Coolant Bypass Valve on my Toyota Corolla 2020 is faulty. An "Engine Maintance Required" code appeared a couple months ago, when the vehicle was still under 60K miles. The vehicle is available for inspection upon request. A faulty coolant bypass valve can cause the engine to overheat or leak coolant, leading to potential breakdowns or accidents. It may also trigger warning lights and reduce cabin heating, creating further safety risks. Not confirmed by dealership/indepenent service center. Only confirmed by personal inspection. The vehicle/component has not been inspected by manufactuer/police/insurance representatives. "Engine Maintance Required" message appeared on digitial display of vehicle. Message does not appear when the vehcile is turned on while A/C system is left OFF, but upon turning on the A/C, the maintaince required message appears, indiciating a faulty bypass valve.
coolant bypass valve is defective and failed prematurely. coolant bypass valve cracks and leaks coolant. Once coolant beings leaking, it comes into contact with the electrical connector located near the valve. The coolant corrodes and damages the connector, which eventually causes connector to malfunction. This causes the coolant bypass valve to be stuck in the -??open-?? or -??closed-?? position (i.e. it no longer responds to the needs of the engine), restricting coolant flow and allowing the engine to overheat. I had to repair the vehicle at Harvey's Autotech 521 West Sixth Street Corona, CA 92882 (951) 737-9878 at the cost of $643.91and loss of a work day.

Unfortunately I take my vehicle to toyota for all oil changes etc and this was not mentioned.

"Engine Maintenance Required See Dealer" Message on Dash Display Engine Coolant Bypass Valve I see this incident repeated for the recent Corolla SE and RAV 4 multiple times with no recall/resolution other than Toyota customers should be prepared to spend close to $750 to fix and replace this part that only takes about 20 minutes to be replaced. This is not new to Toyota. This a rip off. A lot money was paid for the car. Went to dealer less than a year ago and purchased a 2020 SE with a $23,323 price tag. Including dealer fees, finance charges and extended warranties the total price comes to $39,000+. I feel cheated as a customer. A practically new car comes with a defective part and it is not covered by warranty"? Come on. I've trusted and recommended Toyota for years. Do you no longer stand by your company name" Need a better resolution. Please.
