Is it possible for an external source to trigger the system? While traveling on the interstate recently, all four tires show yellow, Still @ 39psi. Got to my destination, reset the system, all is well now. Car is 6 months old, 2500 miles. 1st & only issue, so far.

Doubt it.. when you initialize it on the idrive it "learns" with the frequency and location of each tire. God knows what kind of frequency wave you got hit with.. I'd be worried my boys would be swimming in circles now.. haha. Tires showing yellow would mean the idrive lost it's settings and thought it was low in tire pressure. 39psi certainly shouldn't be low unless yours is set waaay too high.

Thx 88,
Could have a been a rogue wave, in any case, the boys seem ok!
