My 2019 Sierra SLT came with a set of TPMS valves for my trailer, and I finally got them installed. Local garage used their tool to "learn" the positions and everything worked fine. Having TP and wheel temp from the trailer was nice!
Worked all the way home, but next time I turned on the truck and hooked up the trailer, the TPMS system was reset, and it needed to be configured again! I set it up using a manual method, and everything seemed set up correctly, however same problem. Turned the truck off and on again, and all the settings were erased.
I won't be able to get to my dealer for a while to make them fix this, so I was wondering if anyone has run into this, and knows what I might be doing wrong, or what the fix is?
Like everything else these days, its probably a software glitch... *sigh*
