Im posting this for an issue related to the wheels on my mom G6. Her car has less than 30k miles on it, see very little winter driving at all, but the tires dont hold air. It has been back to the dealership many time to remount the tires and this last time the dealership told her that the aluminum is corroding away along the bead edge and will probably never hold air. My dad called GM and they basically told him that it was his problem to deal with. Anyway has anyone else have any issues with wheel corrosion?
