When traveling back from Idaho, we stopped at the Boise service center to see if they could quickly fix it. They were the ones that said the coolant was low but he said it was very minor and not the cause. They flushed & filled but it still wasn't working and we were out of time so we continued back to Seattle. I had them pass their notes to the Bellevue service center which performed the work mentioned above. They advised me to leave the system in AUTO at 70F degrees for the rest of the drive and that worked. It wasn't as warm as I would have liked but it was tolerable and got us home safely. If your car is having issues, that might work for you while waiting to get fixed. I've also heard discussions online about louvers in the front grill getting frozen open with slush/ice which seems like a plausible cause to me and certainly inline with the conditions I had in Idaho so that could also be the cause. Might be worth getting down on your knees and looking through the front grill to see if your car is doing that.Makes sense. My build is July 2021 so I am likely a few revisions ahead of your original supermanifold. At this stage I think the software-based solutions have been exhausted for me. The low refrigerant matter is interesting.. any idea if your error code was trying to tell us this? I wonder if under extreme conditions such as deep cold the pressures are such that it becomes damaged or a leak occurs otherwise. The manifold is not visible from the frunk without disassembly so I have no idea which revision I am on now.
Fingers crossed they don't strand me in Halifax too long while they address this.
My take is there are probably a variety of contributors which is why it wasn't detected until the "perfect storm" of conditions appeared. Tesla seems to be giving this the highest priority and I'm very happy with them. I don't think people should be angry or try to pressure them via gov intervention. They are doing the best they can to fix cars as quickly as possible. I've certainly had much worse problems / experience with legacy brands such as BMW & Chevy so this is par for the course of vehicle ownership.
