About a week ago, my 2015 P85D air condition went completely out in the heat of the day. No air blowing through the vents at all. At 7:00 PM that day, I checked it and the A/C still would not come on. I went to my Tesla app and scheduled an appointment for a few days later. By the next morning, I checked the A/C again, and this time it was operating normally. I let Tesla know that it was an off & on thing with the A/C. It was not a complete shut down of the system.
I was a bit alarmed because a friend of mine in Dallas who has an MS90 told me his A/C completely shut down to the point where the car would not operate. If there is no A/C system to cool the battery down, the car will shut down. And that amounts to a 6K repair bill.
Well, thank goodness, that didn't happen to me. The A/C has been working fine since the day it stopped. Just letting it rest overnight allowed it to fix itself. I took my MS into the Service Center anyway to have them check it out. They were not able to replicate what had happened. And the A/C system is fine according to their diagnosis. Service charge was $0.00 which I was most grateful for, and it included a loaner car.
I told the service rep about the experience my friend had in Dallas. And I asked him if sometimes during the heat of the day will the A/C system focus all of its cooling power onto the battery, and shut off the cool air to the cabin. And he affirmed that does happen.
Has this happened to anybody else? First time in 6 years for me.
