We'll, this is special

I had a low-tire light this morning, so went to the gas station. Brought all the tires up to pressure, got in to drive away, & it feels like my brake is set. It's not. Get out to look. My L front tire is now visibly flat. As is my R rear.

The mechanic - and boy am I glad I went to an old-school gas station for air this morning - just came in & told me my pressure sensors are broken.

"And that makes my tires lose pressure? How does that work?"

Turns out the pressure sensors are built into the valve stems. And by inflating them this icy morning, I caused two of them to freeze. Or so they tell me.
