F Sport tire pressure
I keep mine at 35.5 PSI. The door jamb sticker states 33 PSI.
After driving a few miles it climbes to 38-39 PSI (it was almost 85 deg. today while driving)
Is this ok?

Mine are a mess. One tire says 40, one says 33, the other two 34. Then this morning my low air notice came on. 5th tire registering 27. This is the third notice since I got the car. Taking it in tomorrow.

I've taken the car each time to the dealership. They say nothing is wrong, fill it up and off I go. This time I'll get my oil changed and get them to seriously review each tire. We shall see.

If right after or during your daily drive you check the pressures again and find that a tire has lost or gained a significant amount of air, then it could be one of following issues: a tire's seal is leaking and might need to be replaced or one of your tpms sensors is malfunctioning. Good luck!

Chances are that they inflated your tires while they were warm. Check the pressures before your first drive of the day, after the car has been sitting overnight. Use your own air compressor like suggested to inflate as needed. Check the pressure on your air compressor and see if it matches your car's monitor. If they are way off, sure something might be up with your sensors. If they more or less match one another and any tire still is overinflated, release a little air to get it into the range of 33 psi range cold, including the spare. It will take a few tries to get it right where you want it. If you want a firmer ride, you may want to use 35psi as a cold baseline, which is ok too; it's just a personal preference.
