Pontiac G6 Reliability?

I have sold well over 30 G6 sedans from my lot aside from the problems with the hard top convertible we have had very few problems with the G6. I believe it to be a vocal minority. As the woman who bought the G6 convertible said to me she was going to complain to every website she could find about the problems she had. What really made my day was when she talked to the original owner "she did not buy the car from my store" he told her the car had been hit in the back but the shop told him that everything was fixed. He was just worried about the problems that might come later.
