I would like to know what recourse owners who have had the upgrade and have dead batteries can get in forcing the dealer IE Nissan into replacing the batteries and plugging up their service bay with the car constantly being towed in to address a dead car. I mean sure you can keep the car on a maintainer, and do battery disconnects and fuse pulls and keep on going.... but I wonder if Nissan would jump into action once it starts costing them money. Right now it just costs us money so Nissan could care less. It is pathetic.
I am glad I held off on the upgrade thanks to the good people here telling us of these issues. But I still find it maddening we are so far along this path and Nissan has not made customers whole. That just is not acceptable to push out a customer paid for upgrade that damages car batteries and creates problems with the functionality as designed into the car. This is really sad.
Your denying yourself the advantages of a functioning TCU, because of the possibility of a problem. Yes, there are those with TCU issues, but not everyone has been negatively affected. 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.
