There is a known issue with the coolant bypass valve failing. Dealerships are charging over $600 to fix and many people are having the same issue. The engine maintenance required message is persistent, and will not allow you to bypass it.

- Austin, TX, USA

The vehicle has a message engine maintenance required. The Toyota dealership diagnostic was that the coolant bypass valve needed to be replaced. The dealer told us they are getting at least 6 Rav4 a week coming in with the same issue. The part replacement isn't covered manufacturer under warranty. This needs to be a recalled part.

Coolant Bypass Valve failure/malfunction. Frequently reported issue for model/year.

- Oakley, KS, USA

The coolant bypass valve is defective on a 3 year old single owner, well maintained under 50,000 miles vehicle. This is a wide spread and known issue for Toyota which can result in engine overheating, causing potentially unsafe situations to occur for the driver. This can also severely damage the engine.

The Coolant flow control valve is malfunctioning. This was diagnosed by a Toyota dealer. My car is 3 years old and has 56k miles. Upon doing more research, a lot of people have complained that the same things are happening to their vehicles as well. To my understanding, this is not something typical for a car as young as mine.

- Bartlett, TN, USA

Coolant Bypass Value Replacement required on my 2020 Rav 4. I have 33,000 miles & purchased in 2019, so it is not covered under warranty. The dealer is charging me over $850 to replace. I have been told by the Dealer that this is a "KNOWN" problem with this and other Toyota models. Why is there not a recall or extended warranty on this repair if so many owners are paying hundreds of dollars on relatively newer cars with the same FAULTY PRODUCT? I would like Toyota to reimburse me. I am having the car repaired tomorrow because I have been told it is dangerous to use the vehicle in this condition. Please assist me with ways to get reimbursed from Toyota and for others to receive repairs at no cost, especially on vehicles under 5 or 6 yrs old. thank you.

Coolant valve replacement

At approximately 60K on my 2020 Toyota Rav4 XLE The Engine Maintenance Required Visit Your Dealer message came on my dash. It's been a known issue for many Rav4's not to mention other Toyota models for the engine coolant bypass switch to have gone bad. The vehicle is available for inspection upon request. My safety and whom I may be transporting can be put at risk if the engine refuses to start or operate as normal and can leave us stranded. The problem is known by Toyota and many of these valves have been replaced at the dealer for a very high cost.

2020 Toyota Rav4, just around 25K miles, took to dealership to get regular maintenance service, (oil change, tire rotation). After a couple days, "engine maintenance required" message pops up. Plugged in code reader and brings up code "P268115" for "Engine Coolant Bypass Valve Circuit Short to Battery or Open". This issue is popping up for many recent year Toyota models (Rav4, Camry, Corolla) and is not being repaired by Toyota for free. They are charging $600 - $1000 to repair faulty part that is not the owner's fault and issue needs to be recalled.

- Lemon Grove, CA, USA

Dash reported "Engine Maintenance Required / Visit Dealer" - dealer said it was a "coolant bypass hose", not covered by any warranty. $100 part but engine-out procedure costs $800. This vehicle has less than 40,000 miles.

- Arlington, TX, USA

Car has 26K miles on it (3 year 2 months old). A light appears saying Emergency Engine Maintenance is required. After research as this error is not in manual, found out it was a failed coolant bypass valve and this was a common failure/faulty equipment but we are being asked to pay full price to repair. A simple internet search shows 100's of consumers with same issue in same model and low miles.

- Westford, MA, USA

Coolant Bypass Valve breaks easily and in many RAV4s and Corollas. When this happens an "Engine Maintenance Required" see your dealer message comes up in the heads up display and won't go away. Makes seeing the important details of speed, miles to empty, etc on the screen impossible read. It is a known issue by Toyota and they refuse to do a recall.

Over a month ago, I had an engine maintenance required error light come up on my dashboard. I had done some research and found that this has been an ongoing issue with multiple RAV4s. I discussed this recently with the dealership as well as contacting Toyota-??s customer service and they did not address the issue as a concern and replied I would have to have the dealership run a diagnostic to see what the issue was. I already knew the answer from multiple threads I had read prior to my appointment. I ended up paying $190+ for the diagnostic of what I already knew was going to be the issue. And now I have an appointment to have the part changed next week for another $600+

The coolant bypass valve failed. If this was not repaired it could have resulted in leaking coolant which would eventually cause engine failure. The issue started with a message on the dash stating there was "engine maintenance required" on 6/28/2023. I took my vehicle to my service provider the next day, 06/29/2023. The dealer service tech knew exactly what the issue was before diagnostics because they had 4 RAV4's come in that week with this same issue. The bypass valve was replaced on this visit and I paid for the job. I have since seen many posts online with this same failure on 2019 and 2020 RAV4 models. It appears Toyota had a recall for this in 2020 for Hybrid RAV4's and some non hybrid RAV4's but apparently my vehicle and many others were not included in this recall. https://www.greencarreports.com/news/1127163_some-2019-2020-toyota-and-lexus-hybrids-recalled-for-coolant-leak-concern This recall needs to be extended for the other vehicles like mine that are currently being affected by this faulty part.

Code p268115 part failed at 60k miles outside of warranty. Plastic wasn't designed to withstand normal operation. Cracked and leaks coolant causing a short to battery.

My Toyota 2020 RAV 4 Hybrid accelerates in REVERSE when in drive mode and parked on an incline. My car ran over me on 2 occasions while outside the vehicle. Both times I pulled into my driveway, came to a complete stop, and believed I was parked and the car engine was off. Once I exited, I realized my car was still on, reached inside my car to push the off engine button, and the car IMMEDIATELY ACCELERATED in reverse (while in DRIVE MODE/not REVERSE or PARK MODE), knocked me down and pulled me under the front driver side tire and ran over my legs/body. The fire dept and police arrived to transport me to UCI Trauma Center. The car accelerated so fast that it knocked me down/pulled me under/rolled over my body, then rolled down the driveway, across the street, popped the curb and landed in the neighbor-??s lawn -?" all from the force of acceleration in reverse while in DRIVE mode. This happens whenever the car is in DRIVE mode and you push the OFF button, the car accelerates in reverse when parked on an incline. This happens in parking lots as well with an incline. Toyota Service REFUSES to let me show them this product design defect and how the car accelerates in reverse while in DRIVE MODE when the "on/off" engine button is pushed off and the car is on a slight incline. It is a major hazard to the driver, passengers and community, whoever is standing outside and behind the car. Toyota REFUSES to memorialize this design problem. Our other Toyota cars require the car to be in park before you can shut it off and DO NOT accelerate in reverse when in the drive mode, only when in reverse mode. Toyota maintenance staff told me they are not allowed to memorialize the problem in writing; they won't come to my house to see what happened or let me demonstrate at their service facilities. The police officer told me he has seen this happen before, and that we were lucky no kids in the street were run over, which he said has happened before. How many others were run over?

Engine maintenance required notification came on. Car is only 3 years old. Dealership stated that the coolant bypass valve needs to be replaced and it could potentially cause a fire. Service professional at the dealership stated that this is a common issue and most of the time Toyota warranty doesn't want to repair it, also said that it should be recalled. I have also seen hundreds of people complain about this on Rav4 forums.

I took my vehicle to the dealership (Doral Toyota) on 22-Apr-23 and spoke to Mr. Rafael Sanchez (title: Toyota Advisor) because the "Engime Maintenance Required" light went off. Mr. Sanchez verified the vehicle and confirmed that the "Enginge Coolant Bypass Valve" was defective but he stated that there are 597 other owners also waiting for the same part. They were not able to resolve the issue and no estimated time to get the part.
