Hadn't realized what the sound was for awhile. Never crossed my mind that I had mice in my brand new car! Then I found them!! My husband put "TomCat" in the back and under the hood and they are still there eating my car before I even made second payment. Scared to death that one is going to cross my feet while I am driving or eat through something important and the sensors aren't going to catch it. Sales person wouldn't even return my email asking if it was covered under warranty, but I guess it isn't. Also wanted to know if they would spray something for free... no return call or email. Which in the process of buying got immediate responses of course. This is literally making me sick. After reading up on this I find that Ford and other manufacturers are doing nothing to help car owners.
