It hadn't been driven in a couple days, and it was slightly below 0 C. So I guess it's possible something froze, but it wasn't excessively cold out. I am mostly a one-pedal/regen driver, but the brakes had to have been working a few days prior because the car doesn't fully stop without using the hydraulic brakes to go from low speed -> stopped. But after low speed testing in the parking lot I turned into I couldn't reproduce any failure so I barely had anything to report that would have been credible. I also learned that you can't slam on the parking break (what I would have called an emergency brake in other cars!) because it's software-disabled above very low speeds.

You may have water in your brake fluid then. Brake fluid is very hygroscopic you should totally exchange it very two years or so regardless of how full the container is. Once unstuck it would stay unstuck until the next freezing cycle. You can have a cheap water contents test done for your brake fluid at almost any garage.

If it happens again, remember, Teslas collect and send an enormous amount of telemetry. It's very possible just with a time period they'd be able to look into it.
