this website totally rocks! i bought my '07 G6 in march and i was pretty pissed when i got the "changer parked" message and my car wouldnt start. i got a jump. it started. i havent had the problem since. i was gonna take it to a pontiac dealership but after reading this, i see it's not necessary. thanks for saving me the dianostic fees! god forbid it happens again but i see where the problem comes from so hopefully all the suggestions will help.
