Radio/tape Cd Player problems of the 2002 Nissan Sentra

I own a 2002 Sentra spec v and this is my second one in 10 months that has failed to perform as it should. The current vehicle has had 1 new engine, 1 exhaust manifold, 2 window regulators, 2 new windows, three new door speakers, two shift knobs, 1 timing belt tensioner, 1 third brake light, and is in the process of getting it's third engine. Car consumes oil at a rapid rate of 2 quarts per 1200 miles. Tried an informal resolution and Nissan rejected. Dealer agrees the car should be bought back. Symptoms that I have, lead to possible engine fire and is being addressed with a recall. I was sent home in a vehicle that was unsafe and they did not want to fix this last time and were denying the car had any problem. I fought a long hard battle just to get it fixed.
