Preignition - engine ping

I have a 2017 delivered in January, currently about 9500 miles. Since the truck was delivered, I've had what I'll call "piston slap" at mid range RPMs in second and third gear.

I always use premium fuel, 92+ octane. More recently I've had many instances of engine ping at 4500-5200 RPMs. Mostly at wide open throttle but sometimes at about 75% throttle for short periods. Mostly in 3-5th gear.

Anyone else experiencing similar issues?

No, I have nothing like that. you should try to get a go-pro or cell phone video to illustrate to the dealer though. it’s worth mentioning if you suspect an issue.
