2024 GMC AT4 Valve Body Replacement

GMC2024 · July 25

I have a new 6.2 L Sierra AT4 almost ready to pick up at the dealer. Its a 2024 and through the dealers PDI they noticed the truck would not go above 30 MPH. The tech diagnosed the truck with needing a new valve body. Could there be anything else causing the valve body to fail? The truck is new and oly has 19 miles on it.They are putting one in now but I do not have to take delivery if I dont want to. Could there be anything else wrong? Should I be concerned? Your thoughts and advice are appreciated.
