Unfortunately we cannot tell customers to disconnect their batteries once in awhile as the permanent fix. Haha.
I have found that I can reset the TCU just by going into Carwings settings and "deleting all Carwings settings," then logging in with the ID and PW again, no reset needed. That has helped a few people in this thread and on facebook that I've talked to.
Like I said mine has been working 100% except for a few times when I purposefully took my voltage down to the low 12v range in which case it stopped responding (then I reset my Carwings). I will let you know in another week when I reach 30 days. I also noticed when pinging the car, relays or contactors will click on an off, normal enough, except that they are accompanied by another .5v or so voltage drop on the 12v system, that is on my car with a healthy 12v battery. The very act of pinging the car could send the 12v voltage down below 12v on a weak battery.
Standby mode is a good way to describe it as the car can still update charging stations, navigation, etc. but the apps and websites don't work...until you reset it. I'm very curious as what you describe sounds like a total hardware failure, I guess I will see in 7-10 more days as you've decided 30 days is the magic number.
Also unrelated, Leaf Manager has been down for about 36 hours. Nissanconnect EV still works through the website and the app but Leaf Manager is down. Hopefully not long
I used the app to start my CC just about 2 hours ago.
Edit: Actually, I take that back. My TCU was installed by the dealer on 1/16/17 so my unit has been in my car for over a month now. I was counting 22 days from when I replaced my 12v lead acid battery with a LifePO4 litium battery that has never gone below 13v. And full disclosure I have noticed sometimes on Friday nights into Saturday afternoon my car will not respond and resetting doesn't help, I attribute that to Nissan but have no proof.
