Coolant Bypass Valve seems to have an issue at 60k miles which seems to happen to many people at mileage even lower than mine sometimes! My dad had this issue on his 2021 Corolla at 50k miles.

"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.

"Engine Maintenance Required" sign came on, I took it to the dealership and was told it was the coolant bypass valve and it would be $800. Upon doing some research is see that this is a very common issue for 2020 Toyota Corollas. My car is still under 60,0000 so I'm surprised I need work this experience done already

coolant bypass valve is malfunctioning in 2020 toyota corolla se. upon research this is a known problem in toyota corollas, camrys, rav 4 and prius, and was recommended to report this as a possible recall.

The car is at 58,125 miles and I-??ve had a -??engine maintenance required, please take to dealership-?? message for the past 3 months which will not go away and is just stuck on my dash. An OB2 port scanner shows nothing wrong, but after a diagnosis at toyota it appears I need a new engine coolant bypass valve. As it turns out, many other corolla, rav 4, and camry owners of the same generation (2020 and up) also receive the message and need to get the coolant bypass valves replaced around 30k-60k miles.

"Engine Maintenance Required - Visit Your Dealer" message popped up on my car's (Toyota Corolla 2020) dashboard all of a sudden and I didn't have any issues with engine before. I brought up my card to Toyota Service Center in Sunnyvale, CA and they told me that my car's coolant bypass valve has to be replaced and re-check if it's needed which is an uncertain thing and advised me not driving the car as it may damage the cooling system components or even the engine itself. All of these will cost me 911.58$ which is too much but it's not all yet. I was researching this issue on the Internet and figured out that many people who has the Corolla 2020 and 2021 had the exact same issue. I don't think it's a coincidence. People also complaining about the same issue for Toyota Rav4 and Toyota Camry. I don't want to pay so much money which is almost 1k. I never had any accidents and or crashes.

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.
