I drive a 2008 chevy cobalt lt, i have had to take it in twice to get the turn signals to turn themselves off after turning. the most recent incident is my parking brake, the rachet from what i was told broke off, i asked how they said they did not know. i asked how common this happens they said they have never seen it happen before, yet somehow i am responsible for it. i believe it was a manufacturing defect, parking brakes do not just break like that. i drive a manual and my parking brake is kind of imperative to prevent from rolling when it sparked. *tr
