This problem may be covered under warranty. Ask your GMC dealer.
The ACC will shut off and even cause the vehicle to brake for no reason. It happens a lot but the dealership and GMC say there is no problem. Once it shuts off it will not turn back on. This has almost caused my wife to wreck when it shut off and applied brakes with no other car on the road, and startled her. The video is taken when I was driving after the ACC had shut off and applied the brake. I got back up to speed and tried to reapply the ACC wouldn't engage. I had my wife hand me the phone and I videoed the ACC stating "Temporarily Unavailable". This instance there was no car in front of me or on either side, but there was one behind me who I am sure was not happy when the vehicle in front of him braked for no reason. I have found people online who have GMC vehicle which have done this, but there are too few of us for GMC to actually care.

This was my first documented car problem with having a drained battery. The cruise control was also not working. The dealership replaced the battery and sent my on my way. I should have taken this visit at 16681 miles as an omen for much deeper problems and gotten rid of the car while I still could have claimed lemon law. My car now has 46261 miles on it and has been in the shop for 3 weeks and counting now for continued problems related to having a dead battery. I have taken it in 11 times and counting. They do not know how to fix the problem and there are no recalls (yet). Shift to Park appears intermittently before my car locks me inside, locks me outside, or totally dies.
Over the course of the lifetime of my relatively new car the dealership has (in order of evolution): replaced 2 batteries, replaced 2 fobs, replaced batteries in my fobs, replaced jumper harness, replaced transmission control assembly, replaced body control module, replaced fuel injector, replaced immobilizer control module, replaced brake control module. My car may also need the instrument cluster module and the HVAC module replaced as there were also error messages for those as well. I guess I may not get my car back for weeks, maybe months until they decide how to band aid a problem that GMC does not have a solution for according to the Texas class action lawsuit about "shift to park"
