Bose Sub only works when it wants to?

I had a 2020 Tboss with the bose upgraded stereo and I now have a 2021 Denali HD. Same radio (as far as I know) and it has the same damn issue. The sub has a mind of its own. It comes on when it wants and it's great when it does, however it's not consistent and seems to work less of the time than more of the time. This is across the Genres of Country, Classic Rock, some of that EDM stuff and old school Rap. Any idea how to make the sub work 100% of the time? I have the bass all the way up, volume doesn't matter. I feel like it has a selective crossover but at times that selection is to just not work. Anyone else noticing this? If so is there a fix? Thanks in advance!

I guess this is either a known issue or I'm the only one that notices this sub either pounds some decent bass or seems to shut off with a crossover.
