I posted this in the ZL-1 forum, too. The hill assist on my 2013 does not disengage upon throttle application. I've learned to wait a half second or so then ride the clutch a bit until I can feel the brakes have released. Not ideal. You can also wait until you start moving in the wrong direction, but that defeats the purpose. If you're too eager to get moving, you'll stall or peel out.
It's too bad; I like the idea behind the feature. I'm hopeful Chevy will release a software update to fix the problem. After all, the owner's manual states that the brakes will be released upon throttle activation.
