A week prior to this incident, the 2020 RAV4 was taken to Toyota for its maintenance check where everything was checked, replaced and changed. However, the last two days an incessant message keeps popping up on the dash stating “engine maintenance required… Visit your dealer” taking up the entirety of the middle screen inhibiting my ability from seeing my speed, mileage, distance to empty , time, lane assist and other car information that I normally rely on. I have pressed the “arrow back” or “back” button numerous times but three seconds later the message pops again inhibiting me from being able to use necessary car controls to stay safe. The engine on the 2020 RAV4 needs to be recalled as my car only has 55,000 miles on it. I have talked to numerous professionals within the motor industry in which they state these engines have lower stability and life expectancy than PREVIOUS engines used in older RAV4 models. Not only the engine, but the messaging system within the RAV4 needs to be fixed immediately as the communication of maintenance WHILE driving is a hazard. If I cannot look at texts to even just simply read it, why is there is message bright and in the middle of my dashboard popping every 3 seconds with a bright red triangle stating that I need “engine maintenance required,visit a dealer”. This is a safety issue and one in which almost nearly cost me my life.
I kept getting an engine maintenance message. The coolant bypass assembly failed.
Code P268115... Every time you start the vehicle a message will display a "Engine Maintenance Required" and it will never go away, I was driving off road and the message would get in the way of seeing how my AWD is performing.
I having the engine maintenance like tons of other people and it seems is a 800$ fix..... to many people having the same issue and it seems is the return valve hose for everyone
Check engine warning came on, dealer immediately knew it was coolant bypass valve since this is a very common incident with Rav4s recently. My valve was defective and leaking coolant so I had to get it replaced.
The engine coolant bypass valve has shorted and needs to be replaced. The dealer has confirmed the issue. First noticed when a message on the dash that said to see the dealer for an engine issue
p/a engine coolant bypass valve and coolant, and connector with pigtail, pins are full of corrosion inside connector. Items need to be replaced
Coolant bypass valve on all newer 2019 and up Rav4 models are known to cause issues or break at early mileage usually before 50k miles.

Coolant bypass valve on all newer 2019 and up Rav4 models are known to cause issues or break at early mileage usually before 50k miles. It’s a known problem with Rav4 owners and is backed by many claims on social media websites and internet forums. The cost for diagnostic of “engine maintenance required” message on cars dash can range up to $150 and up for diagnostic fees only at Toyota Dealerships. Other independent mechanics cannot diagnose the problem message. Repair and replacement of $800 for parts and labor is ridiculous.
