Just did a cross country road trip with our new MY...driving through Arizona, etc was brutal- especially when supercharging- cabin temp rarely cooled down (understandably the 100+F degree outside makes it more challenging....but we were sweating the entire trip through the warmer states. we had our dog, too, and he struggled in the back seat. Could it be the heat pump? Help! This is not cool (pun intended).
Submit a service ticket using your app, make sure to give them the dates and times your A/C failed as mine did, the Virtual Tech will want to pull your files.
They replaced the High Pressure Temp Sensor and the Super Manifold, also while it was there I requested the acoustic air compressor blanket. There is now a service bulletin on this issue. My service center had me up and running in less then 24 hours. We have 3 SC here in town and parts came from the other locations
Took my MY into 105 degree weather 2 or 3 days ago and the A/C held up 65 degrees for 7 hours. 3 hours to get to Yermo Ca from San Diego and 4 hours return and I mean Ice Cold.
In the mean time this is what you do to temporary fix this issue,
1. Reboot the car, 2 button steering wheel method
2. Turn the Auto button to off in the A/C screen so you run it manually.
3. Turn on Recirculate air so that you are not blowing hot air from outside.
4. Set the Air temp to 62 - 63 degrees and no lower and definitely not in the Lo setting.
We have found this to work well, also we have found that when setting the A/C to Lo, the cold air will shut down around 77 - 80 degrees and won’t blow cold air at all. You would have to do the reset and follow those steps above.
