4WD Lock is not the same as 4WD Auto, Because there is a physical lock in the transfer case and the truck is not moving sometimes, the wheels have different weight pushing on them or the incline of the hill, it cannot easily lock the 2 drive lines together, best way when standing still is to just put the truck in natural and let the truck move a tiny bit by slowly letting off the brake, this is usually all that is needed for it to transition to the 4WD Lock position. If by doing this in these particular times does not help then check in with your dealer, just see if it can be reproduced easily or they will just say its normal.
