Yes, I went into "settings" and made sure that park assist was enabled. It was. There is an issue with my system, that I am sure. I am trying to figure out what that issue is.

I have noticed this a few times. isnt permanent though.

My park assist will not activate. The message on the DIC just says "park assist off" every time that I toggle the switch (as well as when I start the truck). Anyone else have this issue? - David 2019 Sierra Denali, with ultimate package

this happens to mine... the advice given does not fix it. the guide lines have been missing on mine for a couple weeks now.

the only day it was below freezing my lane assist did not work... it has been fine ever since

this happens to mines multiple times every time that I drive. very annoying. at first I thought the blinkers dont work when it is out, but they do blink... they just dont show you blinking from the DIC. I hope this is not a safety concern.
