I have the same whistle type noise as well. Only happens in more extreme cold temps(-20...-40F)and goes away after driving around for a while. Its not the motor being cold as I can let the jeep warm up all the way to normal operating temp and it's still starts when driving,it's in the drive end of things in my opinion. It's rather annoying and bothers me in the fact that I think something's wrong with my new vehicle. I live in northern Manitoba so it remains these temps all winter long so it's a daily occurrence for me. I've tried to tell my dealer here this is what they tell me "many strange things happen to vehicles in cold temps" "would you like to move at 50km hr in -20...-40F" "that's just the way it is"
So I am glad to see other dealers trying to help you guys.
If I'm reading things correctly after those parts were swapped, the noise is gone? wcjeep?
