when the outdoor temps are in the single digits, what will happen if I leave the phone in the car overnight?

I would suggest you try it out and report back to us??

Pulled from Apple tech spec:

Environmental Requirements
Operating ambient temperature:
32° to 95° F (0° to 35° C)
Nonoperating temperature:
−4° to 113° F (−20° to 45° C)
Relative humidity:
5% to 95% noncondensing
Operating altitude:
tested up to 10,000 feet (3000 m)
 
There’s no reason to do that intentionally and it’s easy pickins if someone were to ever break into the car, but I can see it happening accidentally.

My experience with cold iPhones is the battery takes a huge hit and if it’s old will likely cause a crash of the OS - though it didn’t cause any permanent problem. When the phone warms up it’s fine.

I’d at least warm it up before turning it on or if it was left on but locked, I’d warm it up before attempting to unlock it or charge it.

my area almost never get that cold, so I guess I'll be alright in the winter...

however, the max nonoperating temp of 113° F does concern me... my town gets plenty of 100+ days in the summer... the inside of cars easily go way above 140.(highest I tested in my car was 158 a couple of summer ago... after the car had been sitting in the driveway the whole day) I assume the extreme heat will be very bad for the battery....
 
Max non operating temp is only a suggestion, not a death warrant. My older iPhones have gotten over 115° F in storage all the time during summer. They still seem to work fine.
