This exact thing happened to me yesterday at 4 pm as I was trying to show it off to a co-worker. DEAD. Flat-bed tow truck arrives and driver tells me, "Oh, that is one of those electric cars. They are all a piece of junk." I told him not to touch my vehicle. I hopefully set him straight on keeping his opinions to himself and then we preceeded towing it for an hour to the dealer.
Got a call a while ago that the LEAF Tech line told them to evacuate the AC lines and recharge. I'm headed there soon to test the precool feature from my iPhone. They have it charging up now. They needed new lines for the AC that were non-magnetic so it won't interfer with the electronics.
DON'T PRE-COOL YOUR LEAFS UNTIL THEY FIGURE THIS OUT.
Off to the dealer....

First, the edit: I misunderstood the service manager about needing new lines for the AC that were non-magnetic. These lines were for their AC coolent machine for taking out the coolent and injecting it. So they needed to get non-magnetic hoses so they would not create an electro-static charge. They did not replace the AC hoses in the LEAF.
Update: They took me back to my LEAF in the LEAF repair bay - salesman, general manager, LEAF mechanic, and Service Manager. This repair bay is quite impressive with the red "Zero Emissions" tool box with tools designed to eliminate electro-static discharge and a giant blue hoist that actually lifts the LEAF so the special battery jack can fit under the car.
They had me repeat what I had done yesterday that caused the problem - using my iPhone to turn on the pre-cooling function. It worked fine and the LEAF started correctly. The LEAF mechanic had contacted the LEAF tech line this morning. He found that my AC coolent was under pressure and not over pressure like leafwind's was. He evacuated all the coolent and then refilled it to the recommended level. As he explained this, the general manager told him to do this to every LEAF that arrives until they find out more from Nissan, as a preventive measure. They had two LEAFs delivered today - almost 10 days early.
I was impressed with many things through this repair episode. I felt listened to and cared for. This morning the LEAF mechanic hooked up my vehicle to analyze its systems and he was on the phone with Nissan technicians in California that were being sent all the data at the same time. They were able to analyze it along with the local mechanic. How many car companies do that??
I don't understand all the technology of how this would cause my car to shut down, but the LEAF mechanic did. That is what matters.
Home with my LEAF, plugged in to finish charging up tonight. It's a better evening.

The salesman told me the factory overcharged the A/C. The car went to a fail-safe mode as a result. The technician said there is nothing wrong with the car and assures me that nothing will happen to it again. No one mentions the engineer from Nissan.
Can someone hypothesize how an overcharged A/C would put the car in fail-safe mode? I've never heard of that, but perhaps for an EV, it is necessary to prevent any system from short-circuiting the electrical system?!?
I am astonished to think that Nissan would shut the entire car down due to an A/C malfunction! All they'd have to do is disable the compressor and give a small warning. If this is true, I'm seriously disappointed!
Exactly my thought
Most modern cars have a 2-stage switch, or pressure transducer, that reads the high-side refrigerant line. When it gets a little high, it enables the electric condenser fans, and if it gets too high, it shuts off the compressor. (Not the whole frickin' car!!!)

Seems like almost a no brainer to build this type of functionality it, doesn't it?
You win. A new world's record. You do have incredible luck. I have followed you from the Aptera forum where we both suffered through that mess. I have a May due date. Geez, I was worried I might not even get a delivery in May, but I think this is worse. My sympathies.palmermd said:So for me it was...I got the car at 5pm and it failed me at 5:30pm.
azdre said:Maybe run the A/C with the car not in full-start mode. Or turn on the AC remotely via the website, and 25 minutes later try to move it. 2 of the times it took about a minute of sitting in the car fiddling with the radio before it failed. For everyone, this has been happening when it's pretty warm outside, so that might be a kicker.
