You appear to have a stressed tree due mostly to rapid temperature (freeze/thaw) changes and maybe some soil moisture challenges.
If you water your yard all summer many trees do not develop a strong root system. They don't have to as moisture is readily there in conjunction with regular lawn fertilizing, which also fertilizes the tree. Once irrigation is discontinued in the fall the tree can come to have problems, especially in a dry winter, to keep roots moist.
I don't see any insect or fungal issues, and the woodpecker holes are from a transient species ( Sphyrapicus varius ) usually gone by May and of little concern.
Was there bark litter under the tree? If so woodpeckers or climbing Opossums and Raccoons might incidentally be knocking off loose bark, but unlikely.
There is something going on. I'd let it go until another issue appears .ie. no flowers, falling/stunted/yellowish leaves, or dying branches. If those appear enjoy the delicious apple wood for BBQ.
