-35C here today and I park outside - I have the horrible noise from the transmission (it goes away after a warmup). Sometimes mirrors get stuck if there is too much snow between them and the window (but this clears up fine). Also strange behaviour with the seat warmers - seems they do not turn on during remote starts (not sure if this is starting from FordPass or from the keyfob).

 

I live where it often goes below -20 Celsius and park outside as my wife's vehicle and tractor are in the garage. I notice so pretty strange noises when cold like you but so far no issues. It is nice coming from a diesel where the truck actually warms up pretty quickly. I do disable the auto fold on the mirrors once I head into winter as I have had them freeze in my other vehicles before.

Here is a 9 attempt finally successful attempt up my 800ft steep driveway this year. So far really happy with the winter performance of the truck.

 

I live in Texas and we have had 2 ice storms this winter and have a 2021 powerboost platinum. During both, when there was ice on the ground, I would get tons of proximity warnings like I was going to hit something even if I was in a open parking lot. At one point all my side sensors on the passenger, front and rear were going off simultaneously and it caused the dash screen to just go black and reboot. I had a loaner XLT during the last one and was getting all kind of sensor hijinx with it as well. If it lights up like a xmas tree every time there is snow or ice on the ground, I don't know how you guys up north put up with it. It went away for me once the ground was dry again.
