So today when I went to go drive in the morning as I was getting down the block my oil gauge slowly started going up and up till it hit 80 and stayed there for a while. Then about after 10 mins of driving it completely dropped to 0 . I have no idea what's wrong. it has oil and doesn't feel like its driving bad or different . If anyone can help I'd greatly appreciate it. Thank you in advance.

This thread being in the 2021+ section, why not see the dealer for warranty work? Or are you driving something else? (what? the 2012 Yukon in the thread title?)

Time for a new pressure sensor. Change the screen underneath it too.

Exactly what swathdiver said.... replace the oil pressure sending unit and the screen with it.
Not a horrible job, but you'll need some experience. Or just hire it out... Every mechanic has done at least 2 of these. really common
