Last night, the temps here dropped into the 0 and -teens. With wind chill, it was -40 today. I expected to have SOME issue firing up the Commander this morning, and was surprised how quickly it fired up. BUT, the catch is that it made some strange noises that sounded awful - like a metal on metal screeching. It went away after about 20 seconds, but was disturbing while it was going on. Also, my tire pressure dropped about 8 pounds in each tire. Can anyone from the colder climates relate to this?
