Why does my 2007 Buick Lucerne with the V6 engine fail to come out of 'PARK' intermittently? When this happens, it will usually come out of park if I keep trying long enough. Also, it could be temperature related as it almost always works properly when I first start it up in the morning. I am concerned that as our weather finally warms up here in Minnesota that the problem will get increasingly worse. I've been having the problem for a little over a week and it does seem to be getting more prevalent.
