Your low pressure warning was likely just about to be triggered. The low pressure alert triggers at 25% below the recommended tire pressure of 36PSI. A 25% drop would be 27PSI. Since we can't see the decimal place your tire was still above 27PSI. The reason the range is so large is to prevent false trips in cold weather, since pressure drops as temperature decreases.
Best practice would be to patch the tire from the inside instead of plugging it and hope the screw didn't damage the steel belt.

Recommend pressure for the limited 22 is 33 psi and on the dash no icon I can see anything with the tire pressure.
I turned on the accessory and I don’t see it

Mine is the Canadian Preferred model, the recommended is 36PSI with 15" wheels.
33PSI - 25% would mean the alert would come on at about 25PSI.
The USA manual shows this in Chapter 7:

Being a "car nut" versus a person that really doesn't understand many things like tire pressure, I wonder if I was to continue driving with the 50+psi, and especially in the summer as too how safe that would be, other than wear, so a warning for too much psi might be a good one as well, but I guess that's why the manuals are there, and like me getting a new vehicle that has more things that it has and does versus my previous vehicles, that the toughest thing to was to set up the radio buttons for my favorite stations, or even a person getting their vehicle serviced, and usually part of that was checking tire pressure, and if the mechanic put too much or too little air in the tires, the tire pressure screen, I think is one of the best gauges we've got.

For sure the center of the tire would wear quickly due to over-inflation and handling would be affected from less rubber on the road. Worse case scenario, the tire could blow due to over-heating and the stress of too much air pressure.

Ok thanks
I have two now that would be plug patched. I think I’m gonna buy one new tire lol construction in my area getting tired of all the mess on the roads.
