Rear A/C / Climate Control with Remote Start

[nodistortion]

This is so lame. I'm in Phoenix AZ where it is over 100 degs for 100 days in the summer. Many of those over 110 degs. Black 04/2015 Yukon SLE, NO REAR AC with Remote Start. My wife just got a 2015 Ford Explorer, the AC in that works fantasic with remote start, front and rear.
Come on GM, this is a huge OOPS!
