okay so yesterday after my class i got back to my car and immediately noticed what i thought was a scratch but upon further inspection it turned out to be a crack. its only about a foot long and its not deep but its still their. My parents told me to take it to the dealer and get it fixed, would that be under warantee. i dont know if someone hit me cuz theirs no other damage. the weather has been really cold around here so is it possible that that could have caused this. I just want some input on wut i should do. thanx.
