It may cost me a little time, but it has not cost me any more money that would be expected. I upgraded the TCU, when they first became available, in January 2017. I replaced the original battery (almost 5 years old) in September 2017 with an AGM battery. The need for fuse pulls has greatly decreased since then. When the TCU stops responding, I just do a 30-second fuse pull, and then all is good for another month or two. Yes, it is an inconvenience, but not as much as it would be not having remote access to the car.
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.
