It seems (at least from this thread) that owners reporting these issues all have 2016 MYs. Is that correct? I'd be interested to learn when the P/N was superseded.
I can't figure out from the online parts catalog when the number changed. I think you'd have to call a dealer parts department and get a friendly parts guy to dig through the system to get that info.
The pistons and rings have not changed since 2016. Whatever is causing the low compression problem that has popped up a few times hasn't resulted in any changes there.
