On our first drive back home from the factory, and notice the temperature control is very finicky. Initially we had it set to 72 and it maintained that well. After about 1 hour, we all noticed it was getting cold. And we were having fogging issues on the front window. Selected front window defogger and it went full hot with high fan. Worked to,clear the window. Then after we were too hot went back to defog off. Then it started getting cold and 72 was not maintained. Everything was in auto. We eventually settled it on 83 after trying all different temps. So why such a high temp setting? 72 has always been an optimum temp for cars. Outside temp was about 50. I will reset screen when we are done with breakfast as car is sitting at supercharged now.
