Tank Assembly problems of the 2007 Nissan Armada

I was driving when my vehicle shut down and I lost power steering. Although my gas gauge said 1/4 tank, the end result was that I ran out of gas. I contacted Nissan and they told me that the vehicle was taken in for a previous recall to fix this problem. Obviously it didn't work, and the next time it happens one of my kids could be driving, or it could result in a serious accident. What can I even do to repair it, if the first repair didn't work?.

On June 10th, 2010 I was driving home in the fast lane/ carpool lane (approx 2:15pm) and my car immediately decrease in acceleration. I knew I could not make it over to the right hand shoulder and I had to pull off into the left hand shoulder (this was very unsafe) I immediately called my roadside assistance and while I was on hold a highway patrol officer pulled up behind me. He was able to contact another patrol officer and they stopped all traffic and the first highway patrol officer pushed me to the righthand shoulder. The gas gauge was a little over 1/4 tank. The tow truck arrived and took me to the gas station - after putting in gas the car started right up. The gas station attendant said "wow, another Nissan out of gas - do you know I get so many Armadas' and infinities that come in here with no gas" I received a recall notice approx 2 months ago and immediately went to the Nissan dealership - they informed me that the part was not yet available and they would call me, I contacted the dealership last Friday and again today - they do not expect to receive this part for another 2-3 weeks. I called the Nissan consumer affairs today and there is nothing they can do - I informed them that this was just like Toyota and I requested a rental / loaner vehicle - they could not accomodate that request. This has put me in a terrifying situation. The woman at Nissan consumer told me to keep my tank 1/2 full and I informed her that they letter I just received stated to keep it at a 1/4 tank full so that was a discrepancy.
