Navigational (global Positioning System) Gps problems of the 2005 Chevrolet Tahoe

2005 Chevrolet Tahoe dash guages-speedometer eratic, gives false reading and eventually gets stuck at 120 mph, reset by removing "dic"(dash instrument cluster) fuse and starting vehicle then replacing fuse (found this in a blog about this problem), fixes for unspecified amount of time before failing again. This is a known problem and should be mandatory recall by manufacture, as of now only a "voluntary" class action suite settlement to repair at 7 years or 70,000 miles. Most units fail on, around or after this. This is a huge safety concern. I did not realize I was going over 70 mph in a 55 mph zone as my speedometer was reading 45 mph at this specific malfuction, I turned on my gps to verify because I felt I was going much faster than my speedometer was reading and the gps read over 70 mph!. Please demand a recall for these acknowledged propblems by gm for 2003 thru 2007 model years! this is due to faulty guage motors installed by the maker. I contacted gm and they said recalls are governed by the state therefore it was not recalled and only repair at the specified date milage range in the service bulletin. This is a complete sham, the customer should not have to incur expense because of a known faulty item used in manufacturing. Where is the accountabilty for these people?. . . . Please help!.
