We are staying in a hotel while our move is being done. 3 days ago I got a Check Tire Pressure warning when I started the car. Sure enough, flat RF. Used the compressor and inflated a few PSI over. In 3 days it has not lost a lab. I did not use the sealant.

Mystery is how it can go completely flat in 12 hours then not lose any in 3 days? Vandals? Cap was in place. From my teens I recall you unscrewed the stem and did not hang around to replace the cap.

Watching carefully until I have time for a trip to the shop..

Possibly the surface of the rim is not smooth anymore, inflation from flat to full might have caused it to sit a bit different on the rim.

Check the valve core to see if it is tight. A loose valve core can unscrew while driving, leak air when it cools off, then be tightened just enough to not leak when you refill the tire.

a screw or nail in the tire can create this behavior.

if the object is "just right" in the tire, the seal is maintained. Otherwise you lose air.
...happened to me...
