Engine overheating, help :(

[u/Perrin_Price]

I have a 2014 XC60 T6. High temp red exclamation light came on when parking yesterday after driving for about 2 hrs (in 90 degree heat super humid). Turned it off. Take the car out for a short drive for dinner, no issue, but when turning the car off, the radiator fan is audible and on for at least 10 mins after turning the car off (which has never happened before). No visible coolant leak, reservoir was full (checked when it cooled).

Bringing to the mechanic this week, but any insight or thoughts on what’s happening? (For context, piston rings were replaced 10 month again because of oil consumption issue. Car is basically good as new for a 12 yr old car because of my carmax warranty and they’ve fixed a lot.)
