Lexus GX Coolant Level Issue

I'm having a weird problem with my 2023 Lexus GX hybrid. The coolant level seems low all the time, and the check engine light is on with an error code. I checked the coolant reservoir and hoses, but I don't see any leaks. Any ideas?

That's interesting. I had a similar issue with my old 2018 Volvo XC60. The coolant would drop for no reason, and the warning light would come on. Did you check the radiator cap?

About the radiator cap, what did you notice? Was it broken, or was it not holding pressure?

It looked fine, but it wasn't sealing properly. Coolant was slowly evaporating. It might be worth getting yours checked out.

I had the cooling system checked. It turned out the coolant was low. A refill cost 52€.
