Adaptive Equipment problems of the 2005 Nissan Pathfinder

I felt a grinding nose while shifted and I stop and took the car to a dealer Nissan and the find out a problem from transmission/ radiotor. There was a recall for a faulty radiator who leaks into the transmission that cause the problem and I should pay for the repair on my own. I find out that Nissan knows that problem never sent me a recall for that and I bought the car new I serviced it and all the maintenance at a dealership no word I should change the radiator . The same thing happens to me with my 2002 altima.

8-9-2010 I began having difficulty getting my car to shift into reverse. Within 2 weeks, while driving down a crowded highway, my car wouldn't shift from 3rd to 4th, and I could smell something burning. When I finally found a spot to pull over and park, a large puddle of fluid leaked all over the ground. I was alone, in an area I didn't know, and nearly got rear-ended several times when it wouldn't shift gears. I took it to several shops, and the transmissions was ruined. It would have to be rebuilt or replaced, both totalling thousands of $ I don't have. I borrowed money to have it rebuilt. Within 2 weeks, I started having the same issues. When I took it back to the shop, the technician said radiator coolant had leaked into the transmission and it would have to be rebuilt or replaced again. After looking online, I see hundreds of complaints for the exact same issue. For the fuel system, approximately 5/2010, the fuel gauge will drop to empty, even though there will still be fuel in the tank. Sometimes it will stick to mid-full when there is no fuel. Adaptive equipment, when I start the vehicle and try to warm it up, it will only blow cold air, never warm no matter how long it runs.
