NHTSA Complaint #11707937 — 2008 NISSAN ARMADA

My son & I took the car out two days after I bought it. Wanted to see how things looked at night. I took an unfamiliar rd ,( why,I dont know) Enjoying the ride and all the dash lights and bright headlights. Coming up to what appeared to be a slight downhill, curved rd, The car suddenly would not let me steer or brake or, What the heck! I thought its broken and we are going to crash in the trees! Realizing the car shut itself off,im asking, ok yelling at my son, what do I do??? IT took all I had to try & stay calm, and drive like , back when. (No power steering,)but not sure what to do about brakes. Thank God, I had made that corner ok and as rd leveled, I was slowing enough to pull out of the way of the guy behind me in such a hurry. Pulling to the curb, slowly using ebrake, I stopped finally. Took me a good half hour to stop shaking to get out & let my son have a look. Gas tank still full, as it was a few weeks earlier when we test drove. He tried to start , the engine tried to start but just wouldn't cooperate. Didn't know what to look for under hood. So called a friend who thank goodness found us, bringing a battery, tow hook & gas. Hooked up battery charger, poured a little gas, stood out there freezing till they went to try & start & his magic worked. Started up and was on our way. No problem the rest of the night. Texted the people the next day asking about that & she said they never had any such problem. We tested the battery which was fine & still lots of gas. It happened again a couple weeks later. I inquired again about that problem & a couple other things. But, no the cars been great with only brakes replaced the time they had the vehicle. Ok, well this happen again, so I looked into it only to find there has been a recall on something to do with gastank & floater or such. We noticed if we keep a full tank of gas, It doesn't seem to happen. What I read was a recall which they said had never been a problem & never recieved. Well....??We wonder.
