I have a 2021 3500 Denali Dually. At 2,000 miles, the AC failed pulling my 5th wheel toy hauler from AZ to NY. Had to go half way across the country with no AC. Sucked in a new truck. Once in NY, they said a "module" was bad, replaced it in about an hour, and presto. But, on my way back from NY, it went out again in Texas. Both times, it went out, came back on, off and on until complete fail and blowing out hot, humid air. Once in AZ, took it in, and, they can't see a problem. It fixed itself. But now, it poops out, and recovers, off and on. The dealership said bring it in when it acts up . . . but, of course, the truck knows when it's in the shop and is gas-lighting me. Anyone else going thru this silliness in you new and very expensive truck?
