I have the exact same issue. Just went to the Mississauga SC at 6:15PM and had a tech look at it to determine if it's safe for my trip tomorrow to Ottawa; it turned out it's not. They asked me to come in the morning to hook me up with a rental since Enterprise was already closed and obviously they don't have a loaner for me in a such short notice. They won't be able to work on it until maybe Friday or Saturday. I hate it when I can't use my car when I need it.
