I've had my 2006 G6 GTP for 4 years. It wouldn't restart after it's been drove and at temperature. For The last year, the doors lock and unlock by themselves, repeatedly.

I just seen this video describing my exact problems and many of you guys' problems.
Ground wires. Freaking ground wires! I have researched my problems so many times and spent so much money trying to fix it !
Hope this helps someone else. I'm trying it tomorrow morning!

Thanks for finding and sharing this! I ran into a similar situation on my dad's 05 Buick Lacrosse and made a new chassis ground from the battery to fix it's problem(lost ALL electrical power).
This should greatly help many others here!
