start problems / passlock warning
U.S. H3 owners are reporting a common problem with passlock code and failure to start. problem is with the ignition switch/key. Quick fix is to leave key in run position for 12-15 minutes to see if truck relearns code. Problem should be covered by GM as it is in the U.S. posted with thanks to Hummernetwork, Tuscon Hummer and network members
