2020 Toyota Corolla Engine

I have been a victim of a known defect in Toyotas Coolant Bypass Valve as of recent when approaching my 40000 mile service maintenance.

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.

I was driving in traffic when a warning light comes on it says "engine maintenance required visit your dealer". I have looked everywhere in the manual on this message and unable to find anything no other lights are on or anything to determine the issue. Took it to get checked at autozone no codes came up all is clear. I've read online this is a known issue to replace the coolant bypass valve. Unfortunately I take my vehicle to toyota for all oil changes etc and this was not mentioned.

Engine coolant Bypass Valve issue

Faulty coolant bypass valve needing repair. Manufacturer has open class action lawsuit. My car is also impacted.

An engine maintenance required warning displayed on the car dashboard. Crown Toyota Ontario performed diagnostic inspection and detected that code P268115 - engine coolant bypass valve was defective. Based on research the P268115 - engine coolant bypass valve is a common failure to Toyota Corolla, RAV 4 and Camry by car owners for models manufactured in 2019 - 2023. Toyota Ontario advised that the defect is not covered by warranty. My corolla is a 2020 model with 77,379 mileage on it.

I had called Toyota colonial dealership in Milford CT. After briefly speaking with the service representative, he advised that it’s most likely the engine coolant bypass valve. He said that it is common with my car models. I did some extra research and found out that many others were having the same issue from only having the car for a few years.

The coolant bypass valve on my 2020 Corolla SE has started to go bad. The repairs are over $700. Apparently, this is a well known and documented issue with not just the Corolla but also the RAV-4 models. No recalls have been issues despite this being a known problem.

"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

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.

I discovered that my 2020 Toyota Corolla SE has a Coolant Valve Bypass malfunction coded "p2688115". I have also discovered this a prevalent issue after you hit 70,000 miles. There are forums all over the internet with complaints about the same issue as mine. I did some research and found no recalls. With this being such a common issue for no reason, faulty equipment. The car has been inspected by a Toyota dealer in Bradenton, FL because we had thought the service vehicle message was for a tire rotation. They scanned the vehicle and discovered the fault code "p2688115" after trying to reset it numerous times. The senior tech was the one who scanned it. He knew the exact reason why it was not clearing before scanning the vehicle. He only scanned it to solidify his hypothesis. I then spoke to the service team, they wanted me to bring it in for a diagnosis that would cost $85.00 if my warranty did not cover it. The cost of the part was estimated at around $150.00 plus labor and taxes. It was over a $400.00 repair. For a repair as such, this needs to be recalled. The warning message never went away, if you tried to clear it to view the screen you had about three seconds before it came back on. It is a major safety risk for those who wear glasses and drive at night. I use the screen to keep myself safe and maintain my driving speed. This warning message came on around 70,000. Some so many other individuals have experienced and complained about the same problem. This needs to be escalated. I am not allowed to utilize the safety features my car has to offer. Please take action and commence an investigation.

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.

The engine coolant bypass valve has been confirmed faulty at 47,000 due to failure to actuate. Known issues of engine coolant leaking failure have been reported.

The engine coolant bypass valve is coming up as a code. Around 44k miles. Others have had this problem.

Coolant bypass valve bad at 26000 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.
