Brake pedal doesn't move = need to press really hard to start. Mine did this a few times for no apparent reason. It seems to have fixed itself. Fingers crossed.
Sometimes I wonder if there's something, either environmental-wise, debris or some other factor that causes these to lose vacuum. Mine is usually very simple - rest foot on brake pedal, press button. No effort. but there are times after it sits, or just a rare day where i need to push a bit further. But then, I'm used to driving old vehicles, tractors and so on so have a heavy foot anyway at times, I may just not be noticing it.

I have a 2021 Willys and if I don't drive it for a few days the brake pedal is hard and requires stronger push to start the jeep... once started vacuum is back and restarts are normal. You did mention usually happens after a few days of non use. I wouldn't waste time with dealer, just press harder on pedal.
And if that works it helps to confirm, or at least suggest that loss of vacuum may be the right direction with these times.

This morning I pressed the brake pedal down pretty hard and it started!

It is from letting the JT sit for a few days.

I have gone out after driving my beater van for a couple of weeks to start the JT and the pedal is rock hard, won't move. If you press it once as hard as you can, then push down on it again it will move and the JT will start.

There very well could be a designed bleed off to protect the vacuum system.

Yep, has nothing to do with the number of times it's pressed. Has everything to do with getting it depressed far enough to allow it to start. You can mash it or hit it multiple times to get it depressed further, up to you really, but that's all it is and all it needs.

I’ve had the same thing happen. I drive mine once a week or sometimes once every two weeks. When I press the pedal it is rock hard and it won’t start. I have to press it a couple more times to get it to start.
