I have a 2015 Silverado with the G80. Can anyone shed some light on this? Situation: The rear wheels slip and eventually the G80 pawls spring out to engage the lock. You proceed through your "sticky situation" and at some point drive onto a grippable surface. Do you have to stop the vehicle, or even reverse a little, in order to release those pawls from the notch that they spring into? Just seems like it would stay engaged as long as your wheels keep rotating.
