But they are all really at 32 according to my gauges I've been using forever.

Also, it says PSI in the bottom right corner, so this isn't a units problem.

How do I reset this?

You have your dealer "recalibrate" TPMS system on Star - takes about 45 minutes to download/recalibrate..

I'm having this same issue. Is there a way to re-calibrate the TPMS myself?

You can't re-calibrate them yourself. It's a software issue. I had a similar problem and I had to drop it off.

I thought I was having this problem. The TPMS was reading 50 PSI, so I assumed it was in error. I checked the pressure with an analogue gauge. In horror, I discovered the TPMS was correct! It's a miracle I didn't have a blowout on the way home from the dealer. I specifically asked the salesman to please make sure all of the fluid levels were topped off and the tire pressures were correct. Is that their idea of correct pressure?

i don't know what the deal is, but it seems all my dealers do that. and if it happens on a cold day, and then warms up, and you drive, the psi shoots up. i always check tires after service. and i'm talking mb, gmc, cadillac and subaru. you can really feel the ride difference too. maybe that's what they go after. ron

Yes, I've had other dealers do the same as well. If they're going for ride difference, then they're intentionally giving customers a "harder" ride, which makes no sense. I think it may be because they assume most customers "never" bother to check the pressure (which is true) and they're allowing for air loss.

I'd better check the spare too. That might be at 100 psi.
