Seat Broken problems of the 2005 Chevrolet Trailblazer

I own a 2005 Trailblazer, the first problem had to do with the gas not pumping. It would cause the pump to cut off. The passenger seat's plastic side broke off and now the driver's seat is broke. The driver's lumbar selector quit working. The speedometer has stopped working. I use my gps. Then the fuel gauge quit working, the "dummy light" stays on all the time. Cd is hung up in the radio. The front fan for ac/heating quit working. The other fans work and the ac cools. Evidently there are alot of complains with this certain make/model gm should fix the problems. If they don't fix my problems my nest car will certainly not be an american made one because I haven't seen alot of pride when we have to beg to get our cars fixed when shoddy parts are used on our cars.
