There have been a number of electrical gremlins with the G6, and the dealer experience has not been positive. Which is why I will probably get a Honda next.
Had I not joined this forum I may have never heard these troubles you and others are having. I owned 2 Pontiacs before the G6 and have had great expereinces with them both. Now, with the G6 I am still in favor of Pontiacs cars. Maybe I'm just getting lucky. (?) Sure, there are some small issues that pop up but nothing a little TLC won't cure.
With that being said you need to know I also own a Mazda and it has its share of "little issues" too.
Good Luck!
