Now for the ethical problem. I want to sell the car privately. I will put a larger new battery in it, and I guess I will tell the buyer to check the charge every couple of weeks. I'll have to take a bit off the price, but I cannot in good conscience sell the car without disclosing this.
I think I will by a used ICE car to run for two years or so, because I am not thrilled with any of the electric cars on the road right now, and keep hearing promises of new models.
I am really bummed about this. I love having an electric car to go with my solar panels.
It is refreshing to see others with a sense of ethics. Kudos to you on that.
If this were my car, i would do one remaining thing to rule it out. The 3G telematics is known to randomly drain the battery and cause problems. While I'm not saying that's the issue with the car, I would try disconnecting the TCU entirely, unless you use carwings. The process is quite simple and I posted it here:https://www.mynissanleaf.com/viewtopic.php?t=25949
It took me about 15 minutes and is only low voltage cables.
I understand you may be fully done with the car, and if so, that's more than reasonable. This must be infurating. However, given the TCU has a known fault (although yours has the updated firmware to *supposedly* fix that defect), that would be something good to check. I don't know that the TCU can cause a 2A drain, however...
I can say that while battery issues are common with the Leaf and well-documented, I haven't had any problems with my 2011 except when I went on vacation for 4 weeks and left the HV charger connected. The battery was dead when I got back home. Battery looks pretty old too--it's definitely not AGM. I've checked it with an external charger a few times and it's always topped off, and I haven't done any shunting of the negative terminal or anything.
