shut down time

[wizard4878]

2019 sierra slt 5.3 T1 57K.  After driving to whatever destination, time and distance do not seem to matter,  sometimes I push the button to shut the truck off and it takes up to 15 seconds before it actually does. It is a completely normal shutdown other than the amount of time it takes. This just started about a week ago, and its not every time.  Any one else experience this,  is it something I need to worry about?

I have never seen this happen before, I know that if i don't push the button far enough or for the .25seconds it will stay running, then I have to pushed it harder/longer to shut it down (thinking it was the truck that didn't see that input). If it all of sudden started doing this i would take it into the shop and have it check out.

This is not normal.  Take it to the dealer for troubleshooting.

Never happens with mine. It shuts right down.
