I'm averaging about 3 months between fuse pulls. Annoying, but I need remote access for preheat in winter.

Fuse pulls, dead batteries... Nope, I expect it fixed before I spend money for this.

That is your choice, and your decision. We all have different levels of inconvenience we are willing to accept to gain the levels of convenience that we desire.

Hopefully, Nissan is working on a fix, but I don't see a speedy resolution, or a major recall, in the near future. The upgraded TCU has been available for almost 18 months, with no positive updates from the field, or from Nissan.

I haven't had any problems with the TCU since I deleted my "saved charger locations" many months ago (no fuse pulls/12v issues/nothing). In fact, I just returned from a week-long vacation where I was able to retrieve charge status via the app. As was mentioned, there may be other/different issues with different model years (and battery types), but all relevant info about my Leaf is in my sig.

My saga with TCU upgrade on Leaf 2015 SV is over. It was caused by Data Communications settings to be set to manual and no provider selected. Setting it to auto config (AT&T), corrected the connectivity issue. No issues with 12V battery yet, but it seems to be compromised (by deep discharge) as car was parked on dealer lot for months before I got it. TCU works, but complains of poor reception at home, as it blocked by massive Expedition between Leaf and tower. I have moved Expedition into garage as it started to rust too much for my comfort when left outside, so reception got better.

Posted on another thread. Found this thread to be more active.
9/12/2018... 2012 working, 2013 Not working. Still getting intermittent Low signal error message. Problem is not consistent.
Nissan Support says they are aware of the problem and has escalated the problem.
No remedy in sight. Since I haven't seen any new posting... Is this problem solved? Did it set swept under the rug? Did we just Give up?
I hope this thread is still live. I hope I'm not the only one having this problem.
BTW: Both cars have fresh 12V batteries. 2012 has the new Lizard Battery. Problem started after the 3G upgrade. AT&T says they only provide the service its the Software or Hardware problem. Carwings had me take my car back to check the TCU. got charged $75 to reboot and update TCU. Still problems (Got reimbursed after complained to NissanCare). Service says TCU hardware is working great. Strong Signal, Blames Software. So Support blame hardware, Service (hardware) blames Carewings (Software), Personally I don't care. I just want Nissan to make it work!

I own a 2015 nissan Leaf SV, bought and owned in Canada. I am currently trying to have my TCU upgraded to 3G. I was informed through this site that upgrades on the 2015 model year should be free. My dealer just quoted me $962 to do the upgrade. Unreal. Can anyone provide info for Canadians trying to have this upgrade done on their 2015(free of charge). Any help would be greatly appreciated. Ive been lurking in this forum for years, I've received so much useful advice I cant say thank you enough.

Does the 2G TCU in the car still function? Is 2G service still active in Canada? If so, they are not going to do the upgrade for free. It was done in the states, because 2G service was turned off by AT&T. Since it is a Canadian Leaf, the EV Help Line and Nissan Canada will be your best sources for assistance, if 2G service is turned off and it needs replaced.

Re: NissanConnect EV / Telematics Hardware Update, for the post-2G world

On 11/29/18 I brought my 2011 Leaf in for the TCU upgrade. I got it back with assurances that everything went fine but it would take "a couple of days" before it would actually work. I downloaded the app for my phone and was successful in logging in to the EV Connect portal but I've never been able to get the car to respond after 6 days, either to charge or to start the climate control.

Today I called the main Nissan EV service number and the rep there told me the dealer never registered the telematics unit with Nissan. I went into the dealer and they were very apologetic and said they'd take care of it in 10 or 15 minutes. 50 minutes later the service rep came to get me with a paper in his hand and explained that on 11/30, one day after they did the work on my car, a service bulletin came out requiring both a software upgrade and new hardware module for the telematics in cars in my VIN range. They don't have the part and have ordered it. He showed me the sheet and it was dated 11/30 and had a chart with three rows of VIN numbers with different part numbers listed next to them. He was very embarrassed and apologetic, but the bottom line is that I'll have to take it back and start from scratch after they get the new part. FWIW, he said they have registered my car's telematics with Nissan now. I'm not sure how they can do that without the new part, but maybe that will save a step. Ironically, before I brought the car in last week, I called to be sure they had the part.

So if you are planning to upgrade, be aware that this bulletin just came out and there are three different parts involved, so check to make sure they have the right one for you before you go in. If you've been having problems with your TCU unit, you may want to take it back now that they have supposedly fixed both software and hardware problems.
