2018 Nissan Armada

My 2018 Nissan Armada has had SO MANY issues (probably 15-20) with not starting when cranked. Something is draining its battery. We have had to change the battery so many times (usually 2-3 times every year or two.) This happens without any notice! We have been stranded in other cities, stores, &/or at work. We have tried having it checked out by different repair shops, replacing batteries in key fob, replacing battery MANY TIMES, and checking the brake pedal switch. We are at our Witt’s end with Nissans!

My battery kept dying every 6-12 months for the past 8 years! Every time I took it to the dealer or to other mechanics, they ran diagnostics tests and told me nothing was wrong, even though I knew something was definitely wrong. We found out that MANY other Nissan Armada owners AND Infiniti QX80 owners have been dealing with the exact same thing. They showed us how to cut a wire, that would bypass the IPDM smart charging system. Ever since cutting that wire, my car has been working perfectly, and no more battery dying! Please look into this so others don't deal with what I did. Here's the video that we received that explains everything: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Well wife was driving car on her way to work and it shut off in the middle of traffic. Was no sure what was wrong until I brought it home and started reading the codes. It gave me P0087 P0090 low fuel pressure regulater circuit open and P119C. So I changed out the sensor the in tank fuel pump, high pressure fuel pump and sensor on the evap can. Car still will not start. So I bought a wiring diagram to see were everything was routed and found out the have a built in fuel relay so I bought a new PCM that didn't work so then I found out it there was a fuel pump controller module so change that and still not cranking. Fuel pump flows fuel for a second then shuts off. Now I am not sure what to do now. Truck has been down for 3 weeks now. And been have to renting a car since then.
