My 2021 Toyota Corolla has 43k miles at this moment and the engine coolant bypass valve went out prematurely. There should be a recall on this part because a lot of people are having issues with this part on these cars at such low millage. Thanks

I recently purchased a 2021 Toyota Corolla SE. After a few days the "Engine Maintenance Required - See Dealer" notification appeared. See as it was purchased very recently, I assumed this was the oil maintenance light, and reset it. Later that day, it came back, and I reset it a different method under the assumption I did it wrong. The next day it was back, and that is when I realized it must be something else. So I started doing some research and found lots of other people have had this same issue: 2020-21 Corolla, greater than 30k miles, usually less than 60k, and while the Check Engine Light *DOES NOT TURN ON* the car is throwing an error code: P268115 - Engine Coolant Bypass Valve. Sure enough, I have the codes pulled and I have that code showing up. So I took it to the local Toyota Dealership. They stated that the issue was not a warrantable, so I would likely have to pay out of pocket. After a slight fuss, they agreed to fix it as a "one-time goodwill gesture, performed in the interest of customer satisfaction..." So in the end, they did fix it; I did still have to pay for a diagnostic of the issue which is frustrating, especially since I was dead on in my analysis of the issue. To answer the guideline questions: Engine Coolant Bypass Valve Leaking engine coolant could cause the engine to overheat, which can lead to fires, not exactly ideal. It can also cause electrical shorts, leading to more issues. Yes. Lancaster Toyota confirmed the issue. Yes, Lancaster Toyota confirmed that the part was faulty. They appeared shortly after buying the car. There were no error lights like I'd expect, but there was the constantly appearing "Engine Maintenance Required - See Dealer" message which the Owner's Manual states is simply the 5000 mile Oil Change warning. Hidden behind this message is the error code P268115.

Apparently my car's Engine Coolant Bypass Valve is broken and it's a common case with my car's model that's made after 2020. Seems like it there's a need a recall for such a thing since it's a defective part they knew about since my car was screaming at me for an engine maintenance. However, the check engine wasn't on. I went to Toyota at Elk Grove, CA and knew what the issue was pretty quick and charging me $700 to get it replaced. I feel like it's intentionally being handled poorly so they keep charging me 700 every few years to replace a $80 part. As well my story is very common with other customers of Toyota Cars made after 2020. I wanted to report this since that's potentially harmful to put out a car that could have engine problems easily. Especially it's a fairly newer car. Also, they have yet to replace the part for the known recall on this vehicle.

Engine Maintenance Required message came on. Took the vehicle to the dealership and was told that it was the Cooling Bypass Valve. The service advisor said he knew what the problem was before even looking at the vehicle but still wanted to run a diagnostic and charge $800-$900 for the repair. I was told my vehicle was no longer under warranty.

Engine coolant bypass valve malfunctioned at 34xxx miles, causing -??engine maintenance required-?? this could cause the engine to get too hot or not hot enough and affect the internal components of the engine. After speaking to others with the same model and even other models, it seems to be a ongoing issue for many people.

At 61,000 miles I got an engine maintenance required light. After doing research on the Internet, I see that many people with the corolla similar years have had this issue. It is an engine coolant bypass valve.

Engine code P2681(15) which after lookup is the coolant bypass valve which is a common faulty part that Toyota seems to not care about and charge upwards of 700$ at the dealer to fix. I took the part out and it indeed has a crack around the case

My car reached 52,254 miles and I got a engine maintenance required a scary message I have never seen before I thought it was the oil maintenance one but it-??s not I keep dismissing the message because I can-??t see my speed and it stays in the way I have realized that if I start the car with AC on the message pops up but if I don-??t have ac on and start the car it never appears unless I turn on the ac as the car is already on so it seems to be the coolant valve bypass I received the error message as I was parked for no longer than 40 seconds at most

After hitting 45k miles my engine light turned on and required a coolant bypass valve replacement. This issue has occurred for all Toyota Corolla drivers and rav4 drivers I have came in contact with. This issue should be resolved my car is only 3 years old and should not require pricey engine repairs.

Coolant bypass valve stuck shut at 65k miles. Seems like it-??s a common occurrence with newer Toyotas. Was told to report it as a safety issue.

The engine coolant bypass valve circuit short to battery or open and lower hose - Trouble Code - DTC: P268115. The error message "Engine Maintenance Required - Visit Your Dealer" was consistently popping up and I couldn't see my speed or dash or how many miles I had till empty even after acknowledging the message and pressing ok & back. It would stay on while my car was on no matter what. I couldn't use or see any of my information on my dash. The problem has come up multiple times by different people in the auto forum and I was warned that I would have to replace it again in 15 months. There was no light that came on on my dash just the message that would pop up and block my speed so I couldn't see how fast I was going or when I was going to be out of gas. I'm not sure if it's been inspected by the manufacturer. It first appeared after 3 years of owning my brand new car. I was very shocked that I already needed to replace a part in my engine after only having and driving my car for a short amount of time and 30,000 miles on it. It was an expensive part and caused me to have to guess how fast I was going while driving as I couldn't see or get the message to go away even after acknowledging it. I took it to Toyota and they told me the only way to get the notification to go away was to replace it but they did tell me that they have recently had multiple cars come in with the same issue. I had to drive my car in danger as I couldn't immediately afford to pay to get it fixed right away and was in college away from home and didn't have enough time to leave my car in the shop.

The contact owns a 2021 Toyota Corolla. The contact stated while his granddaughter was driving approximately 20 MPH, the check engine warning light illuminated. Additionally, the Parking Brake and Lane Tracing Assist malfunction indicators were illuminated before the vehicle stalled. The vehicle failed to restart and was later towed to the local dealer who diagnosed the vehicle and determined that the engine control unit software needed to be updated. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was 30,000.

I went in after my vehicle displayed a check engine code after my recent visit to the dealer which included a regular oil change plus multi point inspection. At 51k miles the check engine went on and said immediately to go to the dealer. After paying for the dealer inspection, which was extra money, the issue was the engine coolant bypass valve for my vehicle that failed and leaked. I asked if this was common and the dealer said yes since they've been replacing them. I checked online forums and hundreds of people have had this issue at random miles. This costed me over $900 dollars to repair and could of damaged my cars engine leaving me without a vehicle or cause a safety accident. I paid a hefty bill for a faulty item that should have been recalled since it's quite "common" according to the toyota dealership. I regularly maintain my vehicle with the recommended maintenance and this should have not occurred.

The problem seems to occur when activating the Full-Speed Range Dynamic Radar Cruise Control (DRCC) feature, as detailed next. During a recent trip, the car behaved in a potentially dangerous, life-threatening manner when the DRCC function was activated. Specifically, the car seems to increase the RPM of the engine to dangerous levels when going down a slope even if there is a speed limit set using the cruise control. In other words, the car does not change gear properly to keep the RPM in normal ranges. The engine-??s RPM getting close, entering the red zone indicated by the RPM tachometer, and staying there even for seconds may cause an engine explosion which at highway speeds can be extremely dangerous for the passengers and other nearby vehicles on the road.

Got in the car this morning and the check engine light came on. Needed to get to work so started driving. About 5 minutes later car started shuttering and reduced engine power displayed. Had to do 20 MPH all the way to work. Did not make for a good morning. The lane keep assist and other safety features were turned off as well. Not very safe when driving.
