Sorry if anything like this has been posted before. I searched and couldn't find anything relevant after several pages of search results.
We took my 2018 Model X 75D on a road trip from San Diego CA to Phoenix AZ a couple weeks ago. It's only about a 5-6 hour drive. The nav had us avoid Yuma so it took us a little bit of an odd way. About an hour outside of Buckeye, AZ (our last supercharging stop), we noticed the AC wasn't performing very well. It was about 108 degrees outside. By the time we got to Buckeye, we actually had no AC at all. It was hot air blowing, with a message saying AC reduced while the system was cooling.
We decided to grab a bite to eat. After about a 45 minute break, we still had no AC (and its fan was still going very loudly to cool itself). So we also took the time to upgrade the firmware (went from 2019.20.4.2 to 2019.32.2 at the time). By this time, about 2 hours had passed. We finally had AC to resume the trip into Phoenix.
The next morning we left around 10am. It was already about 90 degrees outside. Nav directed us to the Buckeye supercharge for 15 minutes. After we disconnected and left, we lost AC for a while. It returned partially and we made it to Gila Bend where it wanted us to charge to 100%. We had AC for a while after leaving Gila Bend. Dealing with a head wind, however, we realized we weren't going to make it to El Centro, so we decided to chance it and go to Yuma instead. Shortly before we got to Yuma, we lost AC completely and it did not return for the remaining 3-4 hour drive home. The AC was set to 68 but the interior temperature was showing 107 degrees according to the app. During this time a new message showed up saying that the supercharging rate was reduced (which stayed on for the entire trip home).
It's currently at the SC being checked out because I had never had this happen before. So far they've informed me that it is likely normal, and the log shows the compressor was turned off to prevent the compressor from overheating. Once I got home, the fans on the X continued to blow for over an hour after being parked in my apartment's underground garage.
Since returning, all has been normal with one exception. I've noticed I can't remotely turn on the AC if the interior temperature is over 105 degrees. It just says "failed to turn on climate". They are still looking at that one.
I'm curious... has anyone else experienced this before? How do Teslas (or is it more EV's in general) handle climates like Phoenix in the hottest parts of summer? I know I'm spoiled with San Diego's temperate climate, but that was the worst road trip I've ever taken.
