Tire Bubble problems of the 2006 Ford Freestyle

I have two complaints. I have a 2006 Ford Freestyle. First complaint I purchased my Freestyle in late December 2005 and not even six months later in early June 2006 (only 8,056 miles) about 800 miles from home, my rear right tire blew out. Tire was replaced. When I returned home I went to the dealer and I was told the warranty does not cover the tire. Then again in November 2006 there was a bubble in my left rear tire. Tire was replaced. Was told not under warranty. Second complaint at 18,770 miles I had to replace rear brakes that were worn to metal. The r-r rotor was damaged so the rear pad/shoes, one rotor, and brakes were replaced. One rotor was resurfaced. This seemed like a lot of serious work for an automobile that wasn't even two years old. I was a previous owner of a Ford explorer and we didn't have this kind of problem that early.
