Dashboard Failed problems of the 2003 GMC C2500

The instrument cluster has been failing one gauge at the time since 4 years ago, finally it quit all together, I called gm and my local dealership and I was told there was nothing they can do but to charge me for check up and possibly get me a new cluster for 400. 00 what a joke. I know gm has been aware of this problem but nothing gets done. What is it going to take to get gm to get this problems serviced with no cost, after all it's their reputation. . . . I won't buy another gm vehicle.

Oil pressure gauge failure, erratic speedometer and tachometer.
