I've had my 2007 Pontiac G6 in the shop several times for brake "issues". they changed pads, rotors and told me they couldn't stop the squeaking and that the strange "jumping" the brakes seemed to do was "normal" for ABS - which I know is not correct as I have owned many cars with ABS that didn't feel like this. Recently, the traction control light came on, the brakes failed, the emergency brake failed and we hit the back of another car. GM sent an engineer out to look at the event data recorder; however, would not provide me with a copy of the report (they said it was "proprietary"). they are refusing to fix my car and when I asked why the traction control light came on, their "professional" told me "I don't know - I wasn't there!". I've seen several complaints on edmunds.com about the rotors, over-heating problems and the need to have them replaced with non-GM parts to (hopefully) fix the problem. This is a major safety concern for me and I intend to dispose of the car as soon as possible.

Pontiac G6 developed violent vibration when braking at highway speeds. Brake repair shop reported that the rotors had warped due to excessive heat. Also stated this is a frequent problem they see happening every 14,000 to 19,000 miles on many G6's. further reviews of internet forums show many similar experiences. Brake rotors needed to be turned and will need replacement next time. Informed rotors should be a vented style to help with cooling.
