Front Air Bag Sensor Control problems of the 2005 Nissan Pathfinder

While driving down to the title department the day after I purchased my newest vehicle I've ever owned I was hit with the sad reality of an untrue man selling me his problem my transmission has antifreeze in the fluid it will drive fine until it heats up and the fluid gets to the transmission it is not safe this should be a recall they no it's a problem and also my seatbelt light for passenger seat even when someone sit in that seat the sensor does not work.

2005 Nissan Pathfinder le. Passenger side airbag weight sensor in the seat does not consistently detect the presence of my wife who is ~120 lbs. It does intermittently detect her as well as our 90 lbs daughter. We consider this to be a serious safety defect. We have contacted Nissan corporate and had the car to the dealer twice. Nissan corporate will do nothing to fix the defective weight sensor and will not admit that it is malfunctioning.
