seems my 2011 S just doesn’t get cool. It get s cool but not nearly cool enough. Any inherent risks using that do-it-yourself A/C fill up that’s all the rage right now? I assume the capped attachment at the front passenger side is where you add the stuff. Any thoughts?

 

First, don't touch the A/C with being such a new vehicle.
Bring it back to the dealer, have them pull the temperature spec at full max AC and run the car.
If the system DOES NOT put out enough cool, warranty kicks in.

DO NOT attempt to change the amount of refrigerant.
