TPMS - False Warning

[DanH]

After driving for about 5 minutes, the warning message to pull over popped up and stated that my front left tire had only 5 psi. I thought I had run over a nail or something and decided to pull over. Upon inspection, the tire looked normal. I even rebooted the system but the warning didn’t go away. Since there was nothing wrong with the tire physically, I continued with my driving and after a few minutes it changed to 44 psi while the other 3 tires were at 45 psi. However, the warning message didn’t go away. After another 5 minutes, that same problem tire climbed to 45 psi and eventually the warning went away. I’m just glad that I don’t have to deal with a flat tire on a brand new car. But the false reading by the TPMS is still puzzling me.
