Car Complaints GM Sierra

Typical complaints are as follows,

2015, 50k miles, A/C starts blowing warm air. I'm an HVAC tech, checked refrigerant charge with gauges, it's low. Some quick research reveals a known issue with condenser failures, top right corner, look for the oily spot. Dealer wouldn't do anything, will repair myself with aftermarket. Auto parts store stated they sell 3 replacement condensers every 2 weeks. Gm is not going to step up to the plate on this one.
