There's that dealership in Rochester Hills, probably where you bought it. If you're strapped for time, call them ahead of time and tell them of your problem and have them make sure there is a loaner car ready right when you get there. Sometimes it takes a while and they make you fill out all kinds of paper work. Just tell them you need to be in and out quickly. Most of the time they'll be ok with that. if you had a good relationship with the salesman, you can call him and sometimes he will make sure everything goes smooth.

Get it looked at........it's really cold outside!!
