Tire Pressure Monitoring System problems of the 2004 Nissan Maxima

I bought a 2004 Nissan Maxima about 6 months ago and the car has some defects that Nissan should be held responsible for. About a month after I bought the car I noticed a shaking in the steering when I stepped on the brakes or when I drive faster than 50mph. I took it into the dealership where I bought it from and they diagnosed that the rotors were slightly warped but that this wasn't necessarily a safety issue. Recently at 74,000 miles the cars transmission began to fail,slipping from first to second gear and from second to first gear. It jerks aggressively when it shifts and smells like burned rubber. I took it to be serviced for this and found that the transmission fluid was heavily contaminated and there was metallic residue in the transmission pan. The auto specialist determined that the inside of the transmission was burned and that eventually the car will stop working unless I get a new transmission installed. The dealership where I bought the car said that there isn't anything they can do for me and that it isn't there problem that the car I bought from them six months ago doesn't work. It is unfair that I am paying twice the amount of money of the car's worth. The retail value of the vehicle is $10,000 in good condition.
