I meant that the lowest nob temperature isn't necessarily the lowest air temperature at the vent. There's a distinction. My 2003 Yukon, 2009 Yukon, and former Volvo XC90 all said the lowest they would go is 60 on the nob (or LCD). Yet, they all cooled air to 40-45 at the vent.
 
I would say buy a $5 A/C thermometer at Autozone and take it on all of your test drives. Drive a QX56 on a day above 90 and see if it cools the cabin air, but more importantly see how you feel inside. To me, it felt hot even after 20 minutes, and the thermometer (60) backed me up. The rear air (after traveling about 4 feet through the roof of the vehicle) actually came out hot - 71 degrees.
 
FYI - I drove a Sequoia as well and it didn't cool below 55, which was OK but not ideal. I don't know what kind of A/C equipment GMC uses, but as I've said again and again, my new Yukon will get down to about 42 after 5 minutes on the hottest Texas days. I will never overlook the A/C again when buying a new vehicle. Luckily I bought the QX56 in June when I could catch the flaw quickly. Had I bought last winter or spring, I would be sweating like a pig while cruising in syle.

If you put a thermometer at the vent the thermometer will only give the temperature coming out of the vent which is not the temperature of the cabin. That's why weather reporters don't take the outside temperature in direct sunlight. The sun will cause the thermometer to rise and will give a false reading. If you put a thermometer in the cabin and not directly at the vents it will tell you the cabin temperature. Some vehicles will give you the outside temperature and the inside temperature as well. If I ever test drive a QX56 I will be sure to bring a themometer to see how cool it gets the cabin.

Here is a list of problems that I have had with a QX56. According to the internet most of these are common with the QX.
1. Brakes Fail with no explanation
2. Brake Rotors warp at 5,000 mile intervals
3. Automatic skid control actuates unexpectedly.
4. Transmission noise and shifting is irregular
5. Gas Mileage is horrible compared to its competitors
6. Dashboard button for rear hatch release repeatedly breaks.
7. Very harsh ride for a vehicle this price.
8. Dealership is clueless as to many of these problems.
 
Probably THE worst vehicle that I have ever owned.

Try changing the cabin filter ? Maybe the cabin air is not circulating properly ?

I have a 2004 QX with 26900 miles and am being told the AC lines that run to the rear have been corroded ! This is a $1000 repair that is not covered by my extended warranty ! I have called Corporate and will get back if they fix this ! You can't sell vehicles in the Mid Atlantic and blame road salt for doing this kind of damage ! This appears to be a design flaw .

I have the same vehicle and complained about the same noise. The dealer replaced two front sway bar bushings and there is a TSB for a clip that fits on the brake pad and calipers to stop the rattling of the pads with the calipers. The TSB is over a year old

I have this on my 2008, in fact I registered complaints with Nissan and the NHTSA regarding this as I feel it is an unsafe condition. You will see others describing this and the suspension bounce over bumps etc at highway speeds in other posts. As you will see in those other posts Nissan deems this as "normal".

Can you play an Ipod in the QX 56 ? I have tried to plug into the Aux without success.
