It's not necessarily a problem that might require an engine rebuild to fix. When diesels blow a lot of smoke, it's usually because they're getting too much fuel. Take it to a diesel mechanic and have him check it before you go to the extreme of rebuilding the engine.
Clearly, something is draining the battery to cause it to go flat. Check that interior lights are being switched off when you close the doors, and anything else that might not be switching off like it should. It would be a good idea to take it to an auto electrician.
We have had another report of this on another new 7-speed Navara. The dealer told that owner that it was because the transmission has to trawl down through seven gears as it slows, which takes time, but that doesn't ring true. More likely it's a software issue that needs to be addressed by Nissan.
It seems Nissan has agreed to fix the issue under goodwill, so I would start by going back to the company and get that happening. If you don't feel you can do that, there's no other option but to pay for the replacement air box yourself.
There appears to have been little or no warning, which is odd. If it were short of oil I would have expected it to become noisy or hot before it gave up the ghost completely. On most gearboxes you can check the oil level, that's the best way to tell if you've got a problem.
Take a close look to see if you can determine why it is wearing out so fast. Do you sit close to the wheel and brush against the seat back as you get in and out of the car? A simple thing like rolling the seat back before you get out can avoid rubbing against the seat. Of course you then have to reset the seat when you get back in, and that's inconvenient, but it might be a solution. By all means tackle Nissan over it; the seat shouldn't be wearing as rapidly as it seems to be.
It's obviously having a problem when working hard under load. Start by checking the radiator for rubbish blocking the core, look for leaks around the radiator, hoses and fittings. Have the dealer pressurize the cooling system to see if there are any leaks under pressure. Make sure they used the correct coolant.
You're right, the cam timing chain should last the life of the engine. They shouldn't be breaking, particularly at such low kays, as your friend's did. We have had other reports of failures in the Navara, but Nissan appears to be doing nothing about it.
