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.

Performed inspection and verified that pipes to A/C condenser are in fact switched. Discharged system of refrigerant. Switched A/C lines and verified that all O-rings are intact. Performed vacuum on system with a leak test. Vehicle passed the leak test. Charged system back to specifications, and verified that system is blowing cold.
No final update but my X was dropped off five days ago and I've been informed that the compressor has failed and was leaking Freon. Parts pending arrival at the SC. I'll update this thread when I have the car back and have the full story.
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.
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).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.
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.

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.

Lol. But is the Disney one named after my tiny town, or the much larger one by the same name in New York?Just realized something funny...we're staying at Disney Saratoga Springs, and you're from the real thing!

(I was curious; Wikipedia says the latter is indeed correct)
There are a number of X's including mine that had two lines crossed going into the compressor. My biggest compliant was that the car sounded like a jet engine with the fan at the front going crazy. My AC did work... so I thought. The car was so loud that it's embarrassing. After a number of complaints to the SC with the response that it is working as designed I saw a thread here about the issue. Finally someone got their noise issue fixed by having the lines corrected the noise level was totally acceptable/normal. I told my SC and they fixed the problem. When we drive down the street it does not sound like a jet approaching. A side benefit is the AC system works better than before. If your AC is having issues cooling the car I'd recommend having these lines examined to see if it was installed correctly.
Coincidentally my wife was driving the other day and saw another X right next to her. The window was down and she heard the jet engine of the other X as loud as can be. She was going to tell the driver that it is not normal and can be fixed, but the light turned green. Tesla really needs to track down all of the X's with this problem and get it fixed. It is really bad PR to have an electric car literally be the loudest car on the road!
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.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.
Fortunately, R-134a has an almost insignificant effect on the ozone layer.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.
That is one relieving fact. However, it's 1,410x as potent as CO2 when rated as a GHG.Fortunately, R-134a has an almost insignificant effect on the ozone layer.
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.That is one relieving fact.

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
There are two known issues with the Model X A/C that the service center should check. Here's what they wrote in the service notes.
Corrections: Cabin HVAC General Diagnosis
This MX was flagged as having High Refrigerant Discharger Pressure
(THC_w0253_rfrgDisPressHi warning). The discharge pressure can be high if the A/C
condenser lines weren't installed correctly.
Verified A/C lines are installed incorrectly at Condenser. Lines need to be swapped so
that the Compressor Discharge Line is mounted on the top of Condenser.
Corrections: Condenser
Removed and replaced condenser. Recharged AC system

MX COOLING FAN MODULE (1031401-00-E) 1
I've had the obligatory 'sorry we're cooling the battery, so you are going to be hot' message while supercharging in near 100 degree heat. I get this is 'normal'.
But Friday it was over 100 degrees in the San Fernando Valley. No message that it needed to cool the battery and strangely, the A/C would start to blow crazy hot (almost suffocating) air whenever the car stopped at a light or in traffic. I had to shut off the air and open the window whenever the car stopped it was so bad. When it was moving, it seemed to cool somewhat, but still not great.
Worked OK today, but it was not as hot.
Am wondering about the less cooling the hotter it is theory. Tesla is pulling logs.Any ideas?
