Radio/tape Cd Player problems of the 1997 Chevrolet Venture

#1. Stereo panel is extremely hot with lights on & driving a while, there is also a buring smell. It has been worked on twice, replaced once and still you can burn your fingers. #2. Defogger takes forever to defog in the morning, sometimes it makes visibility worse. #3. Interior roof has been hanging down since the day I bought the van and has gotten worse. #4. My headlights have been replaced many times because of condensation(at least 4 times). #5. Brakes. The dealership said I needed new brakes but not under warranty so I had them checked elsewhere. I needed new brakes (front). It cost me over$700 to replace. They said they were grinded down all the way and I should have been able to grind 2 times before replacing. I have the parts. They said the brakes should not have been this far down so soon, too prematurely. I have the bill with the mechanics comments and ii would like reimbursement from gm. #6. Side control panel plastic is broken and controls no longer all work. I have had nothing but problems with this vehicle since the day I bought it. I will be filling out another form to file the remainder of the problems.
