2018 air conditioning

Sitting in the car charging at a Chargepoint on a warmish but not super hot day, and the air conditioning seemed to quit working. Was probably about 40-50 minutes in. Restarted the vehicle and then it started working perfectly again. Some sort of safety shut off?

There is an algorithm in the first gen Leafs that does this under certain circumstances, and I suspect it remains. It's something like 'Reduce A/C output at very low speeds in hot weather until restarted.' I thought my A/C was failing after experiencing it a few times. I seem to remember it happening after I shut the car off to go in a store near the end of a long trip. Did you do something similar?

Ya, it was something pretty similar. Was driving for about 2 hours, then went into a store to go to the bathroom/buy a soda after I started the charger. Came back out and started the vehicle to get some air conditioning. Then after a while it just seemed to slowly quit.

I wonder what their reasoning is for doing that.

Not enough air flow through the condenser? I assume there is an electric fan but that will probably not move as much air through the condenser as fresh air being rammed through the front of the car while it is moving.

Instead of turning the car on while it's charging, remote activate the climate control. It will run for two hours before automatically turning off.

Some additional information about older models (don't know how applicable to the 2018):

When the AC stopped working, did you verify the desired air flow was still in operation? LEAFs tend to change the air flow randomly which can very much feel like the AC compressor has quit.

This is crap. I can't believe this is actually happening on the newer 2018 models. I'm so glad we didn't buy a new 2018 model thinking that it would solve this problem. I won't buy a new 2019 model either if this problem still persists. I'll just take the 60 kWh battery and put it in my 2011, which Nissan would have to do, based on the Nissan Leaf Battery Degradation Class Action Settlement lawsuit, which says Nissan must use the most current up-to-date model year batteries for battery replacements. We've been dealing with this AC blowing warm intermittenly issue for several years, ever since around 2012. In 2011, everything was great car was ALWAYS blowing cool. Then they did a software update and everything went to crap with their AC system. Here in Arizona where its 115 degrees you can definitely feel when it starts blowing warm. I'm sure if you're in Japan or other cooler countries that never go above 85 Degrees you won't even notice it. Here are the links throughout the years with the same stupid problem:

Attn: Nissan, please run a patch to fix this problem. It's very annoying to have to shut your car off and turn it back on at a stoplight just to have the AC work again
