my Toyota RAV4 2019, At around 44500 miles a messaged started to showing up, message was "Engine Maintenance Required" "Visit your Dealer", the message cannot be disregarded, it blocked important part of the dashboard. No other warning light or failure lights were on. Upon taking the vehicle to the Dealer, agent mentioned it could be a non reseted counter for the regular 5000 miles next service reminder, however such maintenance wasn't due, after check by additional person, technician and scan, it turned out to be the bypass valve sticking, code found P268115 and suggested repair for around $900, since vehicle is no longer under the limited warranty cost would have to be covered by the client. Agent told has to be done other wise cooling system for the engine could be at fault causing overheating, and ended up on a mayor engine failure by overheating. It doesn't seem to be a normal failure found on the users manual, hence could be a possible manufacturing fault which Toyota is not covering.

"Engine maintenance required" warning light came on and unable to bypass at all, leaving driver unable to read odometer or speedometer while driving. Had to go to the dealership 2 days in a row before they finally addressed the warning. Service staff informed this is indicating the coolant bypass valve is damaged or has failed. Also informed that this is a very common issue regardless of location, mileage, or usage of vehicle and will happen to all RAV4 owners of certain years eventually. A quick google search will show this is an extremely common issue and a result of using inferior quality parts in manufacturing. Toyota should recall this issue asap and reimburse drivers as many people have had the same problem. Had to pay over $600 at dealership to address issue that Toyota's manufacturing caused and to be able to have full usage of vehicle again. This is a dangerous issue if drivers without financial means to address this problem are driving without being able to use their vehicle display tools among other issues regarding the engine.

I bought this car last year on October 4th from carmax (mileage was 62k at the time of purchase). I started to have problems the next month on November 6th with the brakes which was rusted and had to replace the pads. That was very dangerous and could have hurt myself driving around the heavy rain at the time. I was scared for my safety and others wellbeing so I took the car to the dealership. Their mechanic checked the car and told me that this wasn't fixed or checked since April 2023 before I bought the car in october 2023. I had problems with the infotainment system. the map navigation for my android and iPhone doesnt work anymore. the mechanic at the dealership fixed the rear break pads and discs but couldnt fix the infotainment system even after updating the system. He issued me a 250 dollar refund and was charged 680 dollars for the rest of the job. Another issue happened on March 2024 for the front barring needed to be replaced from a carmax mechanic shop. Paid 380 to fix. This month I got a message saying " engine maintenance required, go to dealership". I took the car to the mechanic and explained that the computer code error message means the coolant valve is defective. I'm thinking of going to the dealer tomorrow up until I found out the car never got the recall repaired from this website. Could this be the reason why I'm having this may problems? The car hasn't been inspected by police or insurance, only the toyota manufacturer on November 6th who told me about the car not getting fixed since April 2023. I have the invoice of all these repairs done. The latest mechanic that told me about the coolant valve being defective thought I needed to change my oil. He did change the oil and charged me 189 dollars. I'm planning on taking the mechanic to fix that problem since the toyota dealership was gonna charge me to fix the transmission fluid which isn't the problem. I will upload the receipt for the oil change job.

#16260-F0010 B/0 PART COOLANT BY-PASS LOST Vehicle is a 2019 RAV4, odometer reads 37849. I've had a persistent "Engine Maintenance Required" notification on the MID screen for the last 1500 miles or so, literally the day after getting a scheduled service at the dealer. I initially thought it was just the service reminder, so I didn't think much of it, and just ignored it. But eventually it became so annoying that I tried to clear the notification, and couldn't-- and upon further research, it turns out the notification is probably the result of a leaking coolant bypass valve. I haven't noticed any loss in coolant, haven't experienced any abnormal engine temps, and haven't had any CELs. I've also noticed that the notification only comes on now when I have the A/C turned on.
