The temperature here has fluctuated a bit from ~0 degrees to ~45 and back lately (New England weather...), but my model 3 is in a heated garage. This morning each of my tires are at 36psi vs 42psi yesterday, and my TPMS indicator is orange. Haven't tested the tires individually yet but this seems to be too proportionate a drop to be an actual reading... Anyone else experience similar?

Tire pressure on all tires dropped proportionately

Get out your old trusty tire gauge. Colder weather does that. I am sure they are that low. Fill them up for winter.
Very common. Even if your garage is heated I bet the floor is actually pretty cold. Unless you also have a heated garage floor? In which case can I be your roommate?
Be careful about adding too much air pressure. Even in cold weather the tires will warm up while driving. Over pressure is more dangerous than under pressure.

I keep my M3 parked outside and the tire pressure does fluctuate in cold weather. It's normal. I've seen mine drop from 42psi to 38psi overnight when the temperature drops by 30 degrees. It's not just Teslas. This happens to all cars. It's physics.
Tire pressure changes with air temperature, around 1psi per 10 degrees F. See https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=73
Tires lose around 1psi per month, they are not perfectly sealed. See: https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=74

It's been my experience that it resets itself after you have filled the tires to the proper PSI and then driven the czar for awhile.

The hard part is finding a czar when you need one...lol

Disproportionate pressure changes are even worse, I mean, you get into your car and one tire is 55PSI and another is 5PSI, you know something is __definitely__ wrong ...
