NHTSA Complaint #11603730 — 2020 TOYOTA RAV4

I got a message popup saying "Engine Maintenance Required" which is different from the oil change reminder. I cleared it thinking it was about an oil change (that isn't due yet), and it came right back. I took it to a mechanic who ran diagnostics and wasn't able to find the issue. After a few internet searches, I found that the coolant bypass valve is a known issue on certain years of this vehicle. I followed the suggested steps for resetting it (to turn on the vehicle with the heater on, then lower the AC temp without hitting the lowest temperature setting). It's currently working as a fix, but I'm concerned about any long-term situations that could arise.
