general problems of the 2001 Nissan Xterra

I just purchased this car about 3 months ago and paid 4000 dollars for it. The vehicle stopped working and the fuel pump wasn't coming on. After searching for the power issue I discovered the fuel tank sending unit which is the top to the gas tank itself. Meaning the service hole of the tank access is the top part of the sending unit. The sending unit has 4 fuel line connections and 4 electrical connections. Two fuel conections and 2 electrical connections plug into the top side of the sending unit and they route through the plastic molded sending unit and connections are made in the bottom side. Basically fuel and electricity route through this unit into the tank. The power wire to the fuel pump burned and melted the conection inside the mold and burned the plastic all around the connection plug where the power goes to the gas tank. From what I understand the 00' and 02' sending units were recalled but not my 01'. This is the equivalent to riding down the road with a ticking time bomb under my children's seats. I have contacted Nissan but I have gotten nowhere with them so I am reaching out to the transportation saftey authorities.

Power window motor & regulater failure, all windows. The window motor and regulater have failed many times. Now my truck is not under warranty and failed again. Many people on many online forums also report the same problem.
