I have a 07 G6 V6 and i am having problems with my front end!! I keep taking my car to the local pontiac dealer only to have them turn or replace my rotars! I have had it up there 5 times for the same thing and now they say there is nothing wrong with it. I also have been experiencing some surging while driving especially about 50 anyone know what this may be from! Its driving me crazy and the people at the dealership prob think i am crazy!!
