Body problems of the 1999 Buick Regal

I have owned this car less than one year and am experiencing extreme paint (dark blue color) flaking. The flaking of paint is occurring around all parts of the car including doors, above wheels, back quarter panel, trunk, and hood. The car has 80,000 miles and has been well maintained--garage kept, washed weekly, and routinely has oil change and check ups. This seems to be a problem with the manufactures paint.

The hvac (temperature control panel) started fading in and out, and then eventually went blank. Seems to work fine. But cannot tell wether the defrost etc. Is set at and what temperature the heat or air is set at. Took to dealer, was told would cost $600. 00 to fix. I also have trouble with water coming into the car on the front passenger side on floor. Have been told that it may be draining in from up under windshield washers. Also, had to replace all four eagle LS tires. I had terrible vibration, took into shop and were told that they were unsafe to drive.
