     My Ultra and VCMI are both up to date. Auto Auth is up to date.
    It cant decode a 2023 GMC 1500 Sierra Denali 3.0L diesel.
    Any ideas?

     Yes 
    VIN:  3GTUUGE89P151583
    P came up.
    I've checked for updates and none are available.
    Is there a way to force an update?
    I suspect this vehicle is too new?

    Hi, I have checked it for you GMC sierra denali is covered only as young as N(2022)
    your car is not yet covered, you could try Chevrolet Tahoe 2023 (P)this car is already in
    the device.
