-??Engine maintenance required - Visit Dealer-?? warning came on. Vehicle was diagnosed with needing a new coolant bypass valve. Researching online, and in Toyota groups, this is a known and widespread issue. The dealer stated they have had many of these repairs come in, yet Toyota has not issued a recall or TSB. This is a repair costing between $500-$1000. That's a healthy sum of money to be spending on a fairly new car.

My Engine maintenance notification came on this week and I took my car for diagnosis. It was determined that it is my the coolant bypass valve was the issue and this seems to be an issue for RAV4s. I researched Recalls for this issue and found a recall code 20TA04 for 2019 - 2020 RAV4 Toyota.I currently drive a 2019 RAV4 but this recall doesn't show under my VIN # But I am having the same issue. Its frustrating when this is a known issue that the dealership is aware of but wants charge large sums of money to fix a problem that is not normal wear and tear. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://static.nhtsa.gov/odi/rcl/2020/RCMN-20V064-1370.pdf

Vehicle had been in for routine maintenance 6 weeks prior. Around 46k miles, the check engine light came on requiring me to bring it back to the Toyota dealer. I wasn't able to bring it to the dealer for about 6 days after it came on due to appointment availabilitly. Once I brought it in, they told me the coolant bypass valve had a circuit short and needed to be replaced. This part was replaced and is unable to be inspected. This is a safety issue especially during the summer as this short could cause the engine to overheat.

2019 Vehicle with less than 45K miles Got a message to take the car to the dealership. Dealership tells me that the coolant bypass valve needs to be replaced. Dealership representative tells me this is a common issue with cars like mine and the part is back ordered for an indeterminate amount of time. After doing some research, I see this is a major issue with quite a few Toyota models, not just Rav4.

Engine maintenance required visit your dealer alert on screen. Seems to happen when the A/C is in use. Took it to a Toyota dealership for a diagnostic test and they said it was the Engine coolant bypass valve. The diagnostic test was $180. They mentioned the part was on backorder and I have been waiting for the part for a month now. The alert will not go away at all if the A/C is in use. The dealership mentioned this has been happening frequently with RAV 4s. It will cost approximately $771 to repair and $189 for a coolant flush.

On May 13, 2023, -??Engine Maintenance Required-Visit Your Dealer-?? warning appeared on my console. I immediately brought the vehicle to the Toyota dealer. I was told the Coolant Bypass Valve went bad. This was at roughly 45,000 miles. I had previously purchased a -??No deductible extended warranty-?? from this same Toyota dealer. Now they tell me this -??Valve-?? is not covered under warranty. I was charged $887.99 for repair of this -??Valve-??. As this could cause the engine to overheat, causing additional damage, it most certainly is a safety issue.

2019 Toyota Rav4 Premium Engine Maintenance light visit dealer popped up on the vehicle. Researching online apparently the coolant bypass valve malfunctioning is a recurring issue with the 2019 Toyota Rav4, not sure why a recall has not been done yet for this vehicle. Went to the dealer to have the vehicle looked at, before having it diagnosed the service person stated it is probably the coolant bypass valve and that the part is on back order, vehicle was put on the machine to have it diagnosed and confirmed that the Coolant Bypass Valve will need to be replaced. The only warning light that it gave me was Engine Maintenance light came on. The service advisor said the vehicle is perfectly fine to drive till they get the part in, which still concerns me because of the engine. I am having to pay out of pocket to get it repaired but after talking to the service people and researching online from other people, there really should be a recall for the Coolant Bypass Valve.

We have a 2019 Toyota Rav4, win VIN JTMK1RFV8KD******, about a week ago this message appeared: "ENGINE MAINTENANCE REQUIRED. VISIT YOUR DEALER." The Mileage was still 74,104. After a week, I took it to a mechanic shop; I had the oil changed and discovered that the message cannot be removed. I had the vehicle system scanned and one of the items that came up is "Engine and engine cooling". My mechanic went on line to find out if there's a RECALL issue on my vehicle with its VIN. There are 8 Recall issues on the KELLY BLUE BOOK website but not on the Toyota website. We called the dealership and they confirmed that my VIN is not included in the list. Toyota is charging $180 or more just to Diagnose. WHY do we have to pay for the Manufacturer's defects?

The Coolant Bypass Valve went bad, and apparently it-??s been happening frequently to a lot of peoples Toyotas. Also unsafe because I have to wait for the part, which is on back order, because so many of them are faulty. This need to me recalled!
