This message has been popping up for a few months on my mom’s RAV4. It’s driving me nuts. None of the warning lights are on. I already reset the maintenance reminder when I did the oil change, but the message still comes back every time. Any help would be great.
You probably need to replace the coolant bypass valve.

Yep, been through it myself. You don’t have to use the dealer unless it’s still under warranty. Mine tried to charge $900, but I bought the part and had a Toyota shop do it for under $300.
They didn’t believe me either. I told them it was the bypass valve, and they acted like I had no clue. When they finally checked and saw I was right, suddenly their attitude changed.
@Afton
I’ve had bad experiences with two Toyota dealers. They don’t take these issues seriously. It’s like they still think these cars are problem-free, but that’s not been my experience.

What should I watch out for if it’s the coolant bypass valve? I keep seeing the message too, but I figured it was just the reminder for tire rotation or oil change.

I’ve had a few small things pop up with my 2019 too. I got it for the reliability but now I’m starting to second guess that choice.
@Afton
Dealer told me it was just the oil change light lol.

Sounds about right. They always avoid calling it what it really is.

Same here. That’s exactly what I was told.

Mine did this at 52k. I’ve got an extended warranty, so I paid $100. The repair invoice was $1100 mostly for labor.
@Thorn
Whew… I’m at 48k right now and was stressing. Glad to hear you were covered.

Yeah it’s just a long hose with a bunch of fittings. It’s tucked behind the engine so a pain to get to.

How do you know for sure that’s the issue?

I’m a service manager at a Toyota shop. Every time we see this message without a check engine light, it’s always the bypass valve.
@fortuna
Which model years are affected?

Mostly 2019 and newer. Haven’t seen it on a 2023 or 2024 yet though.

Just picked up a 2024… will keep that in mind. Appreciate it.

It’s a known issue. Tons of us RAV4 owners have had it. I replaced mine a few months ago.

I had it done under my extended warranty and didn’t pay anything.
Coolant bypass valve. I had the same issue.
