On my 2011 SRX, the A/C seems to come on even though the A/C pushbutton is not selected (not illuminated). I also have not selected the AUTO mode. Also, sometimes an "A" appears in a car icon and outside of the car icon when viewing the air delivery modes. There is no description in the owner's manual of what the "A" means.

Hmmm.... don't know about the "A" in a car icon, but the A/C complaint is common. Our SRX has a cool (no pun intended) feature called Anti-Fog. In the Config Menu (on dash stack) look for Air/Climate control and un-check Auto De-fog , or something like those words. It basically is a feature that senses humidity in the SRX and decides that our windows are likely to fog up, so, ON comes the A/C! No lite will illuminate on dash.

Some complain about being unable to regulate A/C to a warmer setting. Same thing.

You may want to check into the recall they had on 2011's which had to do with defog/defrost/ac systems. See the thread below:

Recall Notice for specific 2011 SRX vehicles - ECC Module reprogramming

I just received a recall notice on my 2011 SRX (Premium Package) regarding HVAC and the possible impact to defrost/defog.

I purchased the vehicle about 5 weeks ago and have not seen any issues with this, but will schedule an appointment anyway (try to get any other software updates while there as well).

Below is the text from my recall notice:

"This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has decided that certain 2011 model year Cadillac SRX vehicles fail to conform to Federal Motor Vehicle Safety Standard 103, Windshield Defrosting and Defogging Systems. As a result, GM is conducting a recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.
Details:
Recall = 11057
Why: Software in the Electronic Climate control (ECC) module may disable the ability to adjust the Heating, Ventilation, and Air Conditioning (HVAC) system settings. If this happens, you will not be able to control the heating, cooling, and ventilation for the vehicle. If this condition affects the defrost system when it is required, it may decrease the driver's visibility, and could possibly result in a crash.

What Cadillac will do: Your Cadillac dealer will reprogram the ECC module. this service will be performed for you at no charge. Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of approximately 25 minutes. If you vehicle is within the new Vehicle Limited Warranty, your dealer may provide you with shuttle service or some other for of courtesy transportation while your vehicle is at the dealership for this repair."
