TPMS issue

Got my Volt a few months ago. Had to have rotors and brakes worked on as mentioned in another post, and all has been good since then. I did, though, have a recent alignment done and two new tires purchased. I had the old tires moved to the front and new tires installed in the back since I had put about 5000 miles on my car since it was purchased.

On my front driver side tire, my TPMS tells me, from time to time, there is a problem. It will last for a while (10-15 min of drive time). TPMS has been relearned by local chevy dealer (and when they looked at the tires, they could find no problems with TPMS), and pressure is ok..The sensor shows that this tire has a problem (I'm assuming with low tire pressure), but readings from gauge/digital pump shows everything is ok.

What are possible causes? I'm only familiar with cars that tell you a tire is low, but my Volt measures pressure for each tire. This has happened for about two weeks. Tire warning light goes on. I measure pressure. Tire pressure is ok. Warning light goes off after a few more minutes of driving.

Low pressure warning comes on at 28. That's way too low. Most of us are running 40 psi , some even as high as 45. Blow them all up to 40 and see if the display agrees.
