On an F250 I had, I went to start it at -40 and the pot metal key assembly just crumbled apart in my hand.

I went to open the hood on my Lexus GX470 last winter at -40 and the hood latch just crumpled apart.

Today I went to plug my car in at -18 and the extension cord jacket peeled apart.

Spend a couple months at -27 to -35, and -10 will feel like a heatwave. I experienced this in bearflanks Alaska. (I actually lived in NP).
