I'm sure there is and your local GMC Dealer will be happy to fix it for free under warranty. Be sure to get a free loaner car if they have to keep it overnight. With this being a GM product be sure to document this and don't let anyone but the Dealer try to fix it. So when this becomes a Lemon Law claim they won't have a leg to stand on! Hope that helps!

Same with my 2024 Denali. I noticed it not working at around 1000 miles

I just discovered that some trailer hitch stingers will interfere with park assist. If there isn't one installed then the dealer is your next stop as it is under warranty.
