I hope you find a solution in your quest because I have the exact same issue you have on my 08 aveo after it's been sitting for some time, it's actually a random occurrence but what remains constant is the duration it has been sitting. I haven't taken any steps to resolve the issue nor do I have a daughter that drives it but I understand your frustration resolving a potential safety hazard that's not always present. I make it a ritual to pump the brakes before I back out of the driveway so I dont just roll out into the street, I patiently await your resolution!
