Park assist not funtioning,is there a repair?
Park assist not functioning only 2300 miles, is there a fix for it?
Make sure it is turned on and if that’s not it then take it back to the dealership for warranty repair.
You have a warranty!
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! Jim
