I would not consider it a good trade to regain the remote features at the expense of a random dead 12v battery and the need to do fuse pulls and resets.

To summarize what I've read so far in this thread:

* It's an unlucky few who have this problem - the majority that have the TCU replaced have no issues.

* The cause of this problem is that the new TCU remains on and does not return to the standby state, thereby draining the 12V battery.

* The TCU gets stuck on for a variety of possible reasons, but there is no complete consensus yet.

* The problem exists in both the earlier 11/12 model years as well as the 13/14/15 model years.

* Those that have issues have a variety of work-arounds, but there is no solution forthcoming from Nissan.


Please correct me if I'm missing something here...



Thanks!

Oak, I am in the same dilemma. Bought my 13sv last July without the upgrade and would love to try the remote functions. I use the timers for getting to and from work. I checked this thread for issues and now am of the attitude "if it ain't broke, don't fix it". I would like to see what the percentages are that have no issues to that of even minor issues (like fuse pulls), before I pull the trigger. My son is bugging me to get this done too.
No word on 4G upgrades yet?

My 2 cents.

I have a '15 SV, and I had the TCU replaced some time ago. I would be pissed if I had to pay, because it works for 3 weeks out of every month... on average. Nevertheless, it is not a huge inconvenience for me, because I have the timers all set. There are times I will like to preheat while it is plugged in, or before I leave the office, but I have grown to accept it.

The original 12v battery has not been replaced, but once a week I plug it into a desulfator, so I may not have a dead battery in the near future.
