The coolant bypass valve failed on my RAV4 at 67,757 miles. There are multiple similar complaints online and I would like to bring it to the attention to the NHTSA. The engine service light cut on and the dealership replaced the valve to make it go away.

Vehicle displayed Engine Maintenance Required light at 54,000 miles. As issue was described from dealer, "Engine code was P268115 for an engine coolant bypass valve circuit short to battery or open. Found Coolant valve intermittently sticking." Was told by technician that if the part was not replaced, the issue could lead to engine overheating and that after they made the fix, they were going to check to see if a gasket was possible blown from the issue resulting from overheating that may have gone overlooked.

2020 RAV4 with 47,589 miles. The engine maintenance light came on. It turns off once I shut off the vehicle and start it up again. It only comes back on when I put the air conditioner or heater on. I was told it's the heater control valve/coolant bypass valve and would cost around $900+ to repair. I did some research and see that this problem is occurring alot.

Coolant bypass valve failed vehicle warning lights came on for this 2020 Toyota Rav4 at 31,641 miles. This is absolutely available for inspection on request. Safety as this can potentially cause overheating, coolant leaking, a cracked cylinder. The manufacturer (Local Toyota dealership - "Ed Morse Delray Toyota" inspected and suggested replacement of the coolant bypass valve for this 2020 toyota rav4 for a price around 800$. the technician say they see a load of these newer model Rav4's needing new coolant bypass valves. I opted not to immediately replace the valve due to it being a vehicle model-wide issue that should likely be a recall. These appeared the day before I brought it in to the dealer so withing 5-10 miles of the 31,641 miles for this 2020 Toyota Rav4. Warning just says "error please take in to dealership for service".

My coolant bypass valve in the engine malfunctioned and shorted at a mere 27,300 miles on the vehicle and I had to bring it into the dealership to be replaced. A coolant bypass valve failing or malfunctioning can cause the engine to overheat, catch fire, or cause complete seizure. Can also cause the vehicle to stall and possibly cause a crash or wreck. Toyota has acknowledged the problem in the RAV4-??s but no recalls have been issued. Dealer knew exactly what the problem was when I mentioned that the -??engine maintenance required-?? light came up on my dashboard BEFORE mechanic diagnosed it and confirmed which tells me they are aware of the issue in these cars.

In September 12,2023 I took my 2020 Toyota Rava 4 vehicle in to Cobb Toyota for a coolant by pass valve to be replaced after my check engine light kept coming on. I only had 25 790 miles on my vehicle at the time. Anthony Sullivan was my service rep. at the time And he stated that this something has been common with this type of vehicle. But could not explain why. I just wanted to report this to Toyota. They need to know about this. And I need to be reimbursed for $99.30 for what I paid for this repair under warranty. Thank you,

At 68,000 miles my Toyota Rav4 needs to have coolant bypass valve replaced. My understanding is this is getting to be a common problem and would like to see it placed on a RECALL. Thank You.

My 2020 Toyota RAV4, "Engine Maintenance Required: See Dealer" message came on my dashboard and would not go away when I cleared it. I took it into the dealership, and they stated that they had 1000s of RAV4's come in with this same message. They said it was the engine's coolant bypass valve. After diagnosing the problem, the dealership confirmed it was the coolant bypass valve. This was very expensive to fix, $926.67, to be exact. For a car that is just over 3 years old, less than 40,000 miles, Toyota knew of these defective parts and still put them in to get the car out of their factory and onto a dealer-??s lot. They do not care if it kills anybody, just get the car sold. Toyota needs to have this bypass valve as a -??recall-?? and issue refunds to THEIR loyal customers, so they call us, loyal customers, not sure how much longer I will be a 'loyal' Toyota customer. I addressed this matter with Toyota Motor Sales U.S.A. Inc. and the dealership I purchased my 2020 RAV4, Milton Martin Toyota of Gainesville, GA. They just blew it off. So, I went to another Toyota dealership to have the repair done.

Coolant Bypass valve has stopped working, which can cause engine issues and forces a message on LED display saying Engine Maintenance Required. Local Toyota technician admitted that they've had 100's of these issues with the Rav4 recently and it costs over $500 to fix.

Engine maintenance light came on and dealership indicates it-??s the coolant bypass valve. This seems to be a common safety issue being ignored by both Toyota and the transportation safety board-??

- Jacksonville, AR, USA

Engine coolant bypass valve needs to be replaced. Seems to be a very common issue in 2019-2023 RAV4s but Toyota has not issued a recall and is making customers pay $600-900 to fix. I ask that Toyota take responsibility and issue the recall now so this can be fixed!

Coolant bypass valve shorts out and doesn't open or close to allow coolant through it. "Engine Maintenance Required" message pops up for this. Toyota dealer inspected it and it replacing the part. NOT covered under my warranty.

Part # 16260-f0010 - engine coolant bypass valve failed due to open or internal short and caused a Engine maintenance required warning which blocked other safety items on the display. This is a wide spread and known issue for Toyota which can result in engine overheating due to leaking coolant and result in engine failure (severely damage the engine) leading to engine stall and/or fire risk, causing potentially unsafe situations to occur for the driver and others in the vehicle. The error code is "P268115" for "Engine Coolant Bypass Valve Circuit Short to Battery or Open". Yes. the problem has been reported with NHTSA by others and from some dealers. When I took the vehicle into the dealership, and they stated that they had many RAV4's come in with this same message. They immediately said it is some engine component failure. There is a related NHTSA Campaign Number: 20V064000 (Engine and Engine Cooling) and also a recall related to it (but not for my vehicle's VIN): [XXX] Yes, the component has been inspected by the dealer. No, there was no warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear Engine maintenance required warning sign did not go off which is good to have warning but blocking other safety items on the display dash board is a safety hazard. This could only be removed if we spend $185 for diagnostics (which is charged knowingly that this has been a reported/unreported problem around the 2.5-4yr/30-60k miles for the vehicles with this part) and fixing the part at the dealer and resetting the code. The cost of the part is affordable but the labor charge of $700 is exorbitant. The part replacement isn't covered under manufacturer's warranty. This part warrants recall as this is accidental poor manufacturing issue that is outside the scope of normal wear and tear and especially when the owner is not at fault. I'm expecting more repairs in future. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

There was a warning message pop up all the time and I went to Toyota service. They said I need to pay for a coolant bypass valve replacement and it costs approx 600-800 dollars. Also, they did not fill up for the engine oil even it-??s in very low to dry position.
