I'm not sure on my build date, but my 2021 is kind of 'Meh.' My 2012 Lonestar blew ice cubes, on 100+ degree days with the fan on '3' (75%)... even after the evaporator developed a leak, eventually failed, and was repaired/replaced by a local mechanic.
The 2021 I give about a 'B+,' because while it still blows very cool, it's not 'cold.' I haven't checked temps with a thermometer yet, but I'd wager they're a bit above spec. I'm going to check the cabin filter (since it IS used with just over 5K miles), observe, then measure. Living in West Texas definitely means we won't be short on hot days while I track this down.
