On vacation and started making a banging and clunking that seemed to be based on speed and not rpm. Dropped family off at the beach and went straight to the dealer. 3 dealers in the area are all booked almost 1 to 2 weeks out. They seem to think lifters but I think something in the drive line. Revving in neutral was fine and when it occurs can definitely feel it in the steering wheel. Wife said it felt similar to when the transmission went out in our '15 Suburban.
Waiting on GM to authorize 2 rental vehicles as they don't have any loaners or rentals in the area that seats 7 (5 kids and 2 adults).
