The parking brake must have been pulled up to it's limit, I'd still try what I recomended, you should be able to try to release the button as the car moves slightly in gear.It is an automatic transmission and the temp last night was probably about 8 F.
I can't even get the button to push in! It has never done this before. My fiance is the one who parked the car last night and he engaged the parking brake further than I normally do.
That's really what I was trying to say, I'll blame it on a headache, damn barometric pressure swing:yell:Did you try lifting up on the brake handle as you push the button?
When I put the brake on, our daughter has the same complaint, so I showed her how to just lift up while pushing the button to release it.
09's are 4 wheel diskIf you have drums in the rear its frozen. Never put the E Brake on in cold weather especially if its a drum. Honestly I am not sure you can do anything til warm weather short of removing the wheel and banging on it. Try backing/going forward with it released (Finger on the button)
