TIRE PRESSURE QUESTION
I own a 2012 Malibu (1640miles) the other day (about a week ago) i received an email from onstar diagnostics telling me all 4 tires were reading 27psi, i had my mechanic bump them up to 31psi, all was well until I was looking over the systems info buttons on the steering wheel, the info center said my tires were now reading 28 psi i live in the east coast (Boston) and we've had some chilly mornings already, i was told this 28 psi reading is a cold reading and it is therefore "normal" is this the case or do i need to have it looked at, i do realize pressure can change and weather can have ALOT to do with it, anyway hopefully, Thank you in advance.

PS : The TPMS (tire pressure monitoring system) light is NOT and has NOT come on , not once, so my way of thinking is why is the pressure going down, should i take a ride to the gas station and bring the tires up the pressure or leave it alone and call the dealer in the morning, quite frankly i would rather take the ride but playing it safe and give a call to the dealer would be smarter i think, who knows, to think i just bought this car about weeks ago.

That's to easy, I'm not taking it to the dealer and waste my day sitting around doing nothing, that's why i came here looking for advice and/or help, thank you.

9one1,
When you changed the pressure in the tires, did you go through the TPMS Sensor Matching Process outlined on p. 10-55 in the manual? Or, alternatively, have you had this checked out by your dealership at this point?

No i didn't do anything with the dealer i did however while i was adding air view the TPMS each time i added air and when i reached the desired pressure i moved onto the next tire until i was finished. I'm getting the oil changed today so I'll have them checked, yet AGAIN.
