RAV4 53,000 miles on and engine maintenance required prompt came on. No other warning lights on dash. Took it to dealership and it was a coolant bypass valve. Read up on it and it-??s been happening to many more people. Was originally charged $900 but got a discount ended up being $825

-Inspection found coolant bypass valve seized recommendation, was to replace coolant hose with bypass valve. YES, the car is available for inspection upon any request -Safety risk unknown if not fixed -Michaels Toyota of Bellevue Washington confirmed on September 23rd 2023. I brought the car in originally on September 9th 2023 for a 10,000 mileage service and oil change. when I called to ask why the engine maintenance notice wouldn't turn off. I was scheduled to bring the car back on September 23, 2023 the needed part was not in stock nor covered by the factory or powertrain warranty with 31,2002 miles on it. The warning light came on at the same time the service and oil change was due. I was stopped a month prior by a random mechanic who noticed the car was leaking abnormal amounts of what he said could be coolant on the passengers front undercarriage. This leaking has been happening for approximately a year and I was not notified the previous 3 times the car had been in for inspections.

Engine maintenance required -??Visit dealer-?? Light is on and won-??t turn off even when resetting the scheduled maintenance data. Needs a 3 point valve according to dealership. $650 cost for that part to make light go away. This is something that needs fixed and recalled as he says it-??s a common issue with the RAV4.

Got an engine maintenance required alert, took to Toyota and they advised the coolant bypass valve needs to be replaced at just 38,000 miles. Googled this and found out many 2020 RAV4 with the same issue at just under 40,000 miles. Also a common issue is the voltage being low and we already had to get the battery replaced once and still get alerts of it being low after replacement. Have to pay today $765 for the coolant bypass to be replaced, will have the receipt later in the day.

I have 2020 Toyota rav4 XLE and all of sudden I got "Engine Maintenance Required" When I turn off the AC, this message goes away but comes in when I turn on the AC. I believe, it is coolant bypass valve which needs to be replaced. I read my forums in [XXX] and [XXX] and many others have complaint about the same. Toyota has to have a recall on this poorly manufactured bypass value. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My RAV4 doesn-??t even have 40,000 miles on it. I found out that the coolant bypass system needs to be replaced. After investigating online, I realized that this is a very common problem for RAVs. I believe this should be a recall!

I have a 2020 RAV4 Toyota with 60,000 miles.. I have replaced the car battery 3 times now Toyota has no clue why. The 2nd battery only lasted 8 months and it was a name brand battery (Die Hard).. The engine problem started with a warning light that i could not turn off.. I took my car to Toyota and they told me right off (without checking) it was because of a Coolant Bypass Value, the Toyota service lady said it was her 5th Rav4 this week with the same problem. I checked on line and was surprised how many Rav4 customers were complaining about the same issue so i reported it to you.. Toyota is charging me $900 to replace.

In my 2020 Toyota RAV4, a "Engine Maintenance Required: See Dealer" message came onto my dashboard and would not go away when I cleared it. I took it into the dealership, and they stated that they had many RAV4's come in with this same message. They said it was most likely 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, and for a car that is just over 3 years old it seems unusual for this to occur so soon and to so many other card within the same year and time period. This part needs to be recalled and reimbursement should be provided to those who had to pay hundreds of dollars to get this fixed when it is very likely a faulty part.

This is a common issue for the 5th Generation Rav4. It doesnt read fault codes on the OBD2 scanner, but the ENGINE MAINTENANCE alert continuously comes up because of a faulty coolant bypass hose/valve. Toyota OEM Part # 16260-f0010. This should be a recall. Instead, we are paying out of pocket to get this fixed.

Coolant Bypass Valve on my 2020 RAV4. There needs to be a recall; even Toyota dealerships in the Dallas/Fort Worth metroplex say that there needs to be a recall. Service advisors say this is a big problem they see daily and with all cars and at all mileage. The cost to replace the Coolant Bypass Valve in my car = $855- RIDICULOUS!! In addition, due to the constant -??Engine Maintenance Required-?? message on the screen triggered by the Coolant Bypass Valve needing to be replaced, that can-??t be removed, all other car related information and/or service issues, is unable to be seen-??which is dangerous!! Toyota used to be one of the best car manufacturers for quality and reliability, but now, their quality has tanked-??

Coolant value had to be replaced apparently this happens more than we realize and if it-??s a repetitive issue for many I believe it should be looked into. Thanks

I was driving and out of nowhere this warning came on engine maintenance required, and this now a normal maintenance required that means an oil change. The problem with this warning is the coolant bypass valve, and I-??m not the only one with this issue, my car has only 32100 miles only, this a ridiculous for a new car. Plus it seem that this issue only comes on with tha A/C

The engine maintenance required light came on at 56,000 miles and would not reset even after a scheduled oil change. The Toyota dealership neglected to evaluate this light when I brought my car in for servicing. After getting a diagnostic, it was found that the coolant bypass valve needed to be replaced which was at least $600. I was advised that the vehicle was to not be driven long distances as it could result in more damage to the car. This is my 4th expensive repair on this 3 year old car in 1 year. This is my very first Toyota, & I am extremely disappointed. I bought a Toyota anticipating a low maintenance, high quality vehicle and have had nothing but issues.

The Engine Maintenance Required Visit your Dealer came on and wouldn-??t go away. I took it into Toyota and they charge $166 dollars to run a diagnostic. Plus what ever it cost to fix it. Turns out that 2020 Toyota RAV 4 Have an issue with the coolant by pass it-??s a pipe if left unfixed it can make the car over heat and it-??s part of the radiator can cost $700 to fix at the dealership. My car is only 3 years old it shouldn-??t have this issues and be costing my hundreds of dollars to fix.
