A new member thankful for the wisdom of this group. I have a '21 Yukon AT4 with ~11K miles. Initially, problems manifest as "service leveling system" and inability to adjust height of ride. First trip to dealer during minus zero weather - no resolution as it was "showing no codes" at time and suspension control started responding again with a software update. Week later (still around 0 degrees), same message came back with additional control (DSC?) related messages including something about engine combustion - dealer captured all codes sent me home (suspension still had air but would not adjust/inflate) with a new appointment for addition overnight diagnosis. Two days later (before the appointment and still seasonably frigid for January in North Dakota), total suspension failure on the front - front tires bowed in - virtually like riding on a steel wheeled steam tractor. Service advisor now says needs a total system rebuild - laundry list of parts. Been waiting for parts for almost two weeks - no ETA on parts - no loaner from the dealer to add insult. Most concerning - it is parked in a dealer storage lot a mile away from the dealership with roughly 8 or 9 other '21's in very similar (deflated) condition some lower than others and some without full front tire tread after driving to the dealer - I am concerned that the wait could be significant and that the fix is adequate. Anyone have any intel on an engineered fix and/or availability of these parts? Looks like these units weren't ready for the cold.![yukon trouble 22.jpg yukon trouble 22.jpg](https://www.tahoeyukonforum.com/data/attachments/355/355317-e7764d0176e8f1d58356c7ffcb30ebf6.jpg)
