When A/C or heat is on the 'auto' setting all of a sudden hot air comes out all vents to a point that it feel like a fire. The only thing to be done is turn the car system off and wait. Very difficult to drive when this happen that's how hot it gets.

300 S 3.6L V6

After doing a software update which was covered under the standard warranty, I began having issues with the heating and cooling not regulating properly. For example, I would have my heat set at 68 degrees and on the "auto" setting, however, after about ten minutes of driving, the heat would be on full blast coming out of all vents. The only way I was able to stop it was to turn on "Max A/C" for a few minutes, then go back to "Auto". After two attempts of fixing the issue at the dealership, they found that the actuator was not working and they replaced it. I have not had any issues with it since.
