Any updates? I'm having the same issue with my 2023 1500 Longhorn for a couple of weeks now. Buttons at left and back of wheel inoperative. Horn, Cruise, Gear Limiter OK.
It's a bummer as I cannot access my Tazer DT without an active Left button on the left side of the wheel.
Update:
Just picked up my truck from the dealer awaiting parts which are 4 weeks out. Diagnosis was "Found SCCM Fault Part Ordered". This would be the Steering Column Control Module, which I assume, for the RAM 1500, is the same thing as the clockspring.
They also diagnosed a non-functioning steering wheel heater as "Heating Element in Steering Wheel Fault Parts Ordered".
Not sure if they just read some codes through a shop scanner or they actually disassembled the steering wheel to check the wiring/ground integrity underneath the airbag. We'll see.
Oh, and they also performed an 08A factory recall: "Flashed PCM from 05149600AD to 05149600AE". Not sure what that's about.
