Lots of us are techs/mechanics, or have been in the past. Plus we are all car nuts, and we love Nissans. Put that together and this is what you get
I wouldn't have agreed to pay any labor charges. If they can't figure out the problem, they shouldn't be charging you anything. At this point, they've already lost out on making money off of you unless it turns out to be something major like a cracked piston (which it's not...I was just throwing that out as an example).
If I were a tech at the dealer, or the service manager, at this point I would be thinking "what the hell is wrong with this damn car? I'm GOING to figure it out". At a certain point the work on the car goes from being a money making factor to being a curiosity factor. You are approaching the curiosity level. The dealer is going to want to find the problem for two reasons. One is to gain knowledge on what could cause the problem so if they see similar symptoms on another vehicle, they won't waste so much time diagnosing it. The other is because they are going to want to show you they are competent enough to fix a complex problem, and try to gain your respect so you return to the dealer (and spend more money in the future).
In the end, when they finally do fix it, parts are probably not going to cost much. You might be out a couple hundred bucks on a switch or some wiring, but I can't imagine it being catastrophic to your wallet. They might hit you with a couple hours diagnostics, but they can't charge you 50 hours of labor to replace your brake sensor switch, even if it takes them 100 hours to figure out that is the problem. The priciest thing I can think of that it could be is maybe the ECU. But my gut feeling says that's not the problem.
The way the service works is that the tech that is working on your car is going to work at it a few more hours. If he still can't find the problem, it's going to get passed on to a master tech if he/she isn't one already.
If the master tech spends a day or two on it and they still can't figure it out, then they will give a call to Nissan's tech line for support. They'll suggest a few things for the master tech to try that he/she may have not have thought of. If none of those solutions do the trick, the final step is Nissan will fly an engineer or two out to the dealer to look at your car. At some point, they will figure it out. The good news is, in the end, regardless of the lengths Nissan goes to fix it, you should only be getting charged to actually fix it, not the gazillion hours it took them to figure out the problem.
