Tire Pressure Issue

Received the "Correct Tire Pressure" error message about 2 weeks ago. Checked all tires, everything was at correct PSI. Let a couple PSI out of the fronts...error message went away.

Came back on Thursday. Went and put air in the tires at a local gas station. 28 in the fronts, 33 in the rears. Cool. Get about 2 miles down the road and the car starts beeping and telling me that one of my tires is significantly low, correct pressure etc. etc.

Drive it home, get out and check pressure....everything is at 28/33 as it should be. No nails, no flats, nothing. Anyone experience something similar? Taking it to the dealer tomorrow for sure. Wonder if it's a faulty TPMS? Perhaps a tire bubble?

It happened to me a few months ago. I put air and ensured that I matched the specs on the placard by the door. After verifying my tire pressure is within specs, I reset/restarted TPMS and haven't had any problem since then.

Get the pressures as you want them on cold tires. Then go into the cluster and set the current pressures as the new values to retain.
