Rather odd tubeless issue!

Has anyone else experienced this issue? I've had a set of Bontrager tyres set up tubeless with Stans sealant for >1 year with no issues at all. This weekend I put the bike in the car on the Friday night to go for a weekend away. By the Sunday both tyres are as flat as a pancake. No obvious sealant leaks and still about 30ml sealant in both tyre.

It was very hot in the car, probably >50 degrees C in the full sun when parked up - could this be the issue? Now I'm home I've pumped them both up and they seem to be holding air again.

Very odd!

    Suspect that the heat expanded something and allowed the air to escape as you've already surmised.
    Too many bikes according to Mrs O.
