I saw this message for the first time last week. I was supercharging at 106 degrees at the time.

Thats incorrect this alert isn't JUST for broken louvers....Your louvers are defective.
Of course it could be something else, that goes without saying. In my case it was defective louvers.Thats incorrect this alert isn't JUST for broken louvers....
On my car they replaced most of the internal ac system before finding a burnt / damaged wiring harness which was the true cause.... Not one line item on my invoice is for defective louvers... sure its one of many things that can cause the issue, but ultimately you need to go to the service center asap to have them diagnose the issue.
Hi Tech_Guy, I have the exact same issues as you. Do you mind telling me which service center you went? I am in Southern CAlifornia. I am really worried they are gona tell me this is NORMAL. I love Tesla but it’s really scary when you can’t depend on a brand new car to have AC when driving in 100 degrees.Yep it will return on a hot day or at a supercharger! You definitely want to get it fixed as the ac is required to keep the battery cool at all times. They will likely have to do a fair amount of trouble shooting to solve it but once it’s done you should be good for even the hottest day!
You should be fine at your local service center, just be sure to reference the dashboard warning and explain what happened before / when you got the message.Hi Tech_Guy, I have the exact same issues as you.

I just went to Costa Mesa service center and they checked and said nothing is wrong!! We were driving up to Mammoth from LA and the AC reduction sign came on while we were driving with 100 miles left on the car. After we supercharged it at the next stop the AC still would not come back on. We had to drive in 100 degrees for another 3 hours. We arrived at Mammoth and stayed there 4 days driving around (cool temperature) and still NO A/C function. We then had to again drive 6 hours back with no AC (4 hours in 90 degrees). The AC was restored the next day after we parked at home garage (Reduction in AC sign off). The next day I went to charge at Supercharger, the sign came on again! After supercharging, sign went off. Please tell me this is NOT normal. I don't want to sit in 100 degrees for another minute again.. so please do share with me which service center you went to?? Please help!!! Thanks.
Centinella Service center fixed mine but again I don't think the service center matters, Maybe speak to the manager at your service center and explain issue and the potential causes you have noticed.... or in this case multiple causes for exampleTech_Guy

Sorry I just saw these last posts because... it's happening again. And it's 97 degrees here today. When I took it in for service the first time they kept it for close to a week and they couldn't figure it out. Then they said the oil in the compressor was low, so they filled it up and gave me the car back. This was in late May. I went issue free until July 4th... since then it's happened three different times. Once I was able to power it off, then restart, and it fixed itself.I also have a 2015 70D and just received this same message. Yesterday, AC wouldn’t get cold. This morning the AC reduced/ DC charging reduced message has appeared. I put in a service request and emailed my local service center I’ll report back once resolved.
@swatkins did you get yours officially resolved?
Did you take yours in and if so, what was the resolution they gave you?
THank youAt service they confirmed refrigerant was low indicating a leak. They fixed the leak and replaced the refrigerant pressure sensor/ intake air temperature sensor. Here are the notes from my invoice:
“Pressure sensor at discharge hose was leaking, necessary to replace. Evacuated system, performed leak test, added oil and freon and checked for other leaks. No other leaks found at this time and A/C is cooling at 42 F.”
Has been working fine for the last week.
I am taking my car in Monday. Today the message came up for the fourth time in eight days. No AC, Dallas TX 95 degrees, black leather, ZERO fun. Anyway, I am sure they are going to replace the compressor this time, but frankly, I don't believe them, because I'm not sure when I brought it in last time they were truly convinced that was the real problem. The reason I say this is because today when I got it home, the fan stayed on for four hours. Not charging, sitting in the garage, doing nothing. I do a factory reset and the message goes away and the fan turns off.... So if the car was hot and diverting compressor energy towards the battery why does the fan stay on for four hours, and more importantly, if it was really hot, why does the fan turn off after a factory reset. So frustrating. I honestly had a thought to sell the damn thing and buy a new model 3 today. That's what blazing heat will do to your brain.Tech_Guy

Any idea how slow supercharging will be without A/C? I’m on a road trip and my compressor “grenaded itself” (the tech’s words!) on the way out. They weren’t able to get parts in before I have to head back, so I’m going to go at night, but I’m worried it’s going to take hours to charge if the battery can’t be conditioned.74,000 Miles. MS 90 D 2016
same warning out of Colorado Springs. "car needs Service" Tesla tech helped rebooting both screens. didn't help.
Supercharged when cold. Air conditioning did not go on.
Got hot, coming into Denver Warnings (5 of them) got dire, "car may not start after stopping."
True! Black screens Tesla towed to service center in Denver (on July 4th, of course)
Begged for help. They Responded. Tesla changed out compressor. All faults were cleared. Had extended warranty, cost $200.
Continued road trip from California to Rhode Island- Florida, Texas, and back home. hot weather all the way. Air working great. No Thump as others have mentioned. 8286 miles 26 days.
Well shiiiit. Answer: it won’t, at all. It starts charging, the A/C compressor groans trying to kick in, and then it stops charging. I am now at the only destination charger within 50 miles, in the only room they had left available. Talk about an adventure .Any idea how slow supercharging will be without A/C?
