Mine has done that before as well, the battery was dying in the sensor. I just replaced them all and never happened again. It might be an antenna in the truck but likely a sensor is dying.
My 2014 does some odd stuff every now and then. Last week I was getting ready to get on the highway sitting at a light, and bam my rear tire reads 10psi?!?!?!?! So I pull out of the turn lane with my infant in the back seat, crawl to the gas station 1 block down and pull in. I jump out and look at the back tire to see if Im lucky enough for a pit stop, (295/65-20 so 35.5 inches tall) and it looks like the rest? I jump in to grab my pressure gauge and its 38 psi. I sit there a second and the truck goes to normal and it reads fine.
Needless to say I have a sensor on order.
I was a bit too enthusiastic to change a tire though. i have my jack and 18v inpact in the bed so I was about to Nascar that SOB
