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
