TPMS Issue 2013 2LT

Not sure if this is the correct place but here goes.....

About two weeks ago the TPMS freaked out on me while driving. The TPMS light started flashing and the DIC read 'service TPMS'. I checked the tire pressure on the DIC and had showed no pressure (-) for the left rear. After a while the light stopped flashing and just stayed on then the system corrects itself and the light goes off and the sensor is reading pressure again.

The second time (on the same trip) the DIC showed it was the left front and went through much the same chain of events.

Took it to the dealership and they replaced both front and rear sensors and all was well for about 2 days. Now it goes through it's routine about 20 minutes into my wife's commute and usually corrects itself by the time she gets to work. On the way home it seems to be a bout a 50/50 chance of it happening at all.

I'm scheduled to take it back to the dealer ship on the 23rd. The two weeks is due to my schedule not theirs.
