My QX56 will not start...battery draining issue

So I must be doing something wrong, but I can not for the life of me figure it out and neither can infiniti.

We had the Battery replaced because we thought it was out of juice. Then we had the starter replaced bc we thought that was the issue.

Two weeks after replacing the stsrter thecar will not start again. Totally dead...seats will not move..nothing.

We turn everything off. Before exiting the vehicle. I mean everything YET something is causing the Battery to drain.

Is this happening to anyone else?
My 2019 Armada is randomly draining the battery too I found this and I am wondering if this could be the problem. The Armada and QX56 have the same motor and wiring as the Titan.

Nissan Recalls Titan Trucks Due To Alternator Wire Harnesses
July 19, 2019 — A Nissan Titan recall has been ordered to repair problems with alternator harnesses that could cause electrical short circuits and fires, or what Nissan calls, "thermal incidents."

More than 101,700 model year 2017-2019 Titan trucks may have harnesses that may have been damaged when the engines were installed.

When the VK56 engines were lowered into place, the alternator harnesses may have made contact with the edges of the metal frame brackets. Nissan says this could cause the harnesses to pull away from their normal routing paths.

The alternator harnesses have shields, but the wiring can become damaged if the harnesses get trapped against the brackets.

If wiring problems occur a driver will likely notice electrical issues such as flickering interior lights or the radio working only part of the time. This can prevent the battery from charging, leading to a discharged battery that may fail while in traffic.

I'm having a similar problem with my 2019 Nissan Armada. Do you have any more details on the technical bulletin you are referencing or a contact number? I've had my car towed to the dealership twice and they won't do anything because they say the battery is testing as "good." It will work for a few days or a few weeks and then the won't start. Anytime they jump it, it works fine for a short while.
I also am having the same problem works fine for a while then battery dies may drive it for a month then same problem I have a 2019 Armada.

Sorry I meant to say QX80 instead of QX56
 
In the midst of the same problem on a 2019 Q80. Had it in the shop now for the third time. First time the swapped out the brand new battery (only had 4k on it). Next time they said they fixed with a software update which effects the way the alternator charges. Now a month later, after getting stuck for the 5th or so time, its back. They say they have another update they are doing, the double secret update. I'm convinced its a lemon and they have no idea how to fix. I will pick up and see how it works and may pursue lemon law on it. I shouldn't have to Uber to work when I am paying for a $70,000 SUV. Will keep you posted if this fix works.
It may be this problem the armada and Q80 have the same motor and wiring if I am not mistaken. I am having the same issue on my 2019 Armada. It has happened 4 times so far.
Randomly, once in Oct., 3 times so far in Feb. Vehicle is fine right now but I have been noticing big swings on the alternator needle in the cluster. Had the Autozone check the battery with a meter said battery was fine but needed charging.Had the alternator checked they said it was fine but the problem wasn't happening when they checked it because it is randomly happening.

So i just got mine back from Infiniti for the 3rd time last night. They swear they have fixed it now, here is what they did: DE-PIN THE IPDM IN ORDER TO HAVE THE ALTERNATOR NOT CYCLE ON AND OFF BUT TO REMAIN ON AT ALL TIMES. IPDM PIN #33
I'm still not convinced and am going to pursue the Lemon Law here in Florida. My wife and kids are driving it and the change they made was described to me and was nearly identical to what they said the last time. Good luck!
So they just masked the real problem or tried to. Right?
