Mine if going in tomorrow, so I will report back. I also have a family vacation kicking of next week, where we plan on taking the MX, and made the SvC aware of that.

Looking at the invoice from the trip to the SvC (don't have the car back yet), I also had the issue with the switched condenser lines:
What I love about Tesla Service: while they took it on the test drive, they noticed a rattle in one of the door panels (nothing I had noticed) and took it upon themselves to fix it.

Sorry to hear that your compressor has failed, but the way I would look at it is that you are getting a *new* part and hopefully with have much better longevity with this fix than say if they just topped off the refrigerant and let you go a few while longer before the A/C isn't cold anymore... so I'm going to drop off my X tomorrow and we'll see how it goes.
Thanks for your comments. The only reason I'm not in complete agreement with your view is that the car was exactly 2 weeks old when I started having problems. Perhaps if I was getting a new compressor for a car nearing the end of warranty coverage I'd be celebrating a bit more. And as for adding freon to a leaky compressor--that wouldn't even have been a competent response. That said, I'm hoping you're facing a less serious scenario.
Update (bad news): Parts still not in sight. Looks like this will be a 3-week+ service call. Model S P85 is nice, but X is sorely missed.
Now the good news: SC customer service has been fantastic. Intelligent, communicative, transparent. They're even going so far as to loan me a Model X from the marketing side to salvage a 4-day trip with kids to Orlando, even though I didn't ask. Impressive, IMO.
I'll note here for the Tesla detractors (and there seem to be plenty) that I've previously had similarly bad luck twice with compressors failing (within the first two months of ownership) on a previously owned new Acura MDX and BMW 535i. So maybe it's me. Also, the quality of the service experience has been far better than anything I've experienced in the past.

Nice. I thought about asking for that when our X went in. Our family simply cannot fit in an S, unless it has rear facing seats (only one of my SC's loaners has them, and it was already out; they rented me an Audi Q7 instead).

The diagnosis for my A/C problems has been confirmed to be crossed lines. The SC actually told me my VIN (34xx) is apparently "in the range" of vehicles that could have crossed lines. When I asked what exactly is that range... they could not tell me. Not sure if they even know since they were looking at only my vehicle. I don't think there is a public TSB about this issue, at least one doesn't exist on the NHTSA website. Neither is there one for my broken door latch and motor.
Though I am relieved to know that my lines were indeed crossed, it still worries me greatly that the A/C did work, albeit not well since delivery... I only have 1200 miles on it and in the past two months, and I was out of town for 3 of those week. Within that time, in particular the last 3 weeks, the A/C rapidly performed worse and worse despite the weather getting cooler and then just started blowing warm/hot air.
So I strongly believe (in my case) that at the very least, the crossed lines (maybe high/low side at condenser) caused failures down the line, perhaps to seals causing a refrigerant leak. That's the best case, and worse case the compressor has been damaged or is just gone.
I am glad to hear that you have been having such a great experience at your SC, sounds like they are really looking into your case and not just applying band-aid fixes. I have questioned my SC to look into possible damage to the A/C system elsewhere due to the crossed lines from the factory. I don't want to go back a few weeks from now for the same issue again!
One of the disappointing things about these refrigerant leaks is the HFCs being released into the atmosphere. At least for those of us who value the climate sustainability benefits of a Tesla.
Just realized something funny...we're staying at Disney Saratoga Springs, and you're from the real thing!

Lol. But is the Disney one named after my tiny town, or the much larger one by the same name in New York?
(I was curious; Wikipedia says the latter is indeed correct)
Very good question--from my vantage (having lived in many parts of this great country) it looks like neither Utah nor NY! But pastoral--at least as much as that is possible in an overpriced resort at a massive theme park. Kids are happy, though, which is what matters.
I just picked my car up Friday, and this weekend we had record hot temperatures here near Philadelphia (98+ with high humidity). When fully on, the AC when standing outside our MX is louder than our central AC unit for our house.
Based on this thread, it sounds like I need to be calling service. Ugh.
Not necessarily. Don't fret. As long as the A/C is cooling well inside, the outside fans can be pretty loud even after they did my repair when I started this thread.
The fans can sound like a jet.
I'm fairly certain they did not swap the lines except on early vins such as our 90D, Vin 1985

That is one relieving fact. However, it's 1,410x as potent as CO2 when rated as a GHG.

Well, we certainly should not just willy nilly dump it out as we please. Since it is several times heavier than air though, having it make it's way to places in the atmosphere where it can do harm is not that big an issue.

Well my VIN is 34xx, so still early but not that low either. It appears to be a range of dates, rather than VINs... likely whoever installed the lines backwards has been "re-trained." My build date is April 2016.

Happy to report that my A/C issues have been resolved (hopefully for the long run)! As previously stated, my lines were indeed crossed, the error was corrected and the only detrimental affect to the A/C system apparently was the need to replace the desiccant bag, which makes sense since the system had to be purged and exposed to atm before re-vacuuming and charging.
The difference is rather amazing... rather the A/C system just works and does not struggle and no more crazy loud A/C fan. I picked it up yesterday afternoon and temps were in the mid-80s with high humidity. I can't believe I just accepted it at first!
The SC was also very professional at handling the issue. There was the unavoidable wait to get into the shop, but at least I had an electric loaner. The staff were all very friendly, open, and engaging, though I did notice some apprehension at first... that is likely for a whole other reason that's not relevant to this thread. There are still a couple outstanding issues that are minor that I need to go back to the SC to address, but with this recent excellent experience, I myself no longer feel apprehensive about it.

Logs didn't show anything, but I finally convinced TM to do a courtesy check of my A/C after being told everything seemed normal. Sure enough, compressor lines were reversed. VIN #13XX. Only wish this had gotten resolved before the summer was nearly over...
