f5stop salesman had four of the valvestem sensors in a bag and stuck them in the glove box and said the would be installed at pdi time . Im a diesel tech for enterprise and am pretty familliar with gm we buy 10's ofthousands of vehicles from them every year . There must have been a vender problem early and thats why so many complaints . Could of even been a soft ware glitch in system much less refined than the system in the vet it gives psi at each tire not just a warning that one is low
