My 2011 Compass Latitude 4x4 has a squeak in the rear of the vehicle over hard bumps, train tracks, etc but only in cold weather. Seems that when the temps reach 20 F or colder, I hear the noise. Last week I didn't hear it at all because it was above freezing when I was doing my driving. Cold weather moved in over the weekend and I noticed it all day long today (it sits outside while I'm at work). When it warms up again, the noise disappears. I was just wondering if anyone else has heard similar issues when the temps drop.
