In the past week I noticed that the leaves are browning (they do have heavy insect damage already though). Started dropping them yesterday. Since the heavy rains we got last month, I've only watered it once (deeply though) – thought maybe it's just thirsty but then I got worried.
Tree has been in the ground a year+, has no missing branches or anything although it has had this one lesion on the trunk since I got it (third pic), large red oaks all around it are completely healthy.

Not oak wilt. Probably heat stress
Pull mulch back 2-3″ from the trunk. Make sure root flare is exposed and it’s not planted too deep. Deep water once a week when it’s over 95F. Consider removing the stakes
