i have a 2006 G6 with just over 78,000 miles on it. I bought it with 73,000 miles on it (i know, thats a lot of miles for a 2006) but, the only thing that I have done to it so far was put new brakes on. There is a rattling noise in the front drivers side corner which i should get checked... and the only other thing i can think of that has happened is one time i left the windows opened and it rained (=[) annd i think it like shorted out the air bag on the passengers side because the service air bag thing came up. However, once it got dried out and such it went away, but thats not really the manufactures fault that happened.
