Carrier/rack problems of the 2005 Nissan Altima

On a recent trip for oil change I asked the dealership about a spot of rust on the rear quarter panel. They said a bracket was rusting that holds the rear quarter panel on. The real problem, they pointed out was the severe rust under the front floorboards, both passenger's and driver's side. I was hoping to get about 6,000 for the car toward the purchase of a new one. I have always had my car serviced at the dealership. The engine runs great it is very upsetting to know that it is dangerous to drive. The Nissan dealership told me there is nothing they can do. They said there is no warranty on the rust.

The vehicle starting losing the paint for no reason ive always taken care of my cars theres no valid reason that this paint should have started to crack like this.

I purchased this car brand new. A little after it was 3 years (08)that I had it the transmission went out. Nissan told me that the car was over mileage so I was responsible out of pocket. So I took it to a mechanic 1200 dollars out of pocket, a little over a year (09), same problem another 1200, in 2012 once again another 1000 and now as of last month transmission number 4 another 1000. As of today July 30. 2013 the car once again is stalling. Freind of mind told me bout the class action lawsuit bout the Nissans trans. As a woman who depends on her car alot I can tell you that owning this car has not been pleasant at all. I have had it stall on me at busy intersections, highways, and in the middle of the nite while working. Nissan doesnt seem to realize that their way of doing business and hiding the truth behind their defective vehicles is and continues to put people lives in jeopardy. All they care about is their product being out on the street. If I would have known that such a pretty car was a peice of crack, I would have spent alot less than 20000 dollars on a new car that was so called good quality.
