Cruise Control problems of the 2003 Chevrolet Trailblazer

I purchased a 2003 chevy Trailblazer one year ago with 63k miles. At 85k miles, the speedometer quit working. Most often, the vehicle defect occurs when the vehicle is in cruise control mode. However, once cruise control is turned off, the defect persists. Even when the car is completely turned off, with the key removed from the ignition, then restarted, the defect persists. There are two types of situations when this problem occurs: 1) the speedometer registers a speed, but it is rougly 15mph less than the vehicles actual speed. This, of course, is quite dangerous if the owner of the vehicle does not know about the defect, for example, if it is happening for the first time. It can be costly to the pocketbook, driving record, and potentially deadly. 2) the car is driving, but the speedometer registers 0mph. When I first noticed the problem, I was driving on a highway. I have a gps feature that allows me to detect speed (thankfully) and accelerated to 80pmh for a brief period of time, but the speedometer still registered 0mph. After doing some research on the internet, I realized this was an extremely common problem, not just with chevy Trailblazers, but with a whole host of other gm vehicles. Additionally, those making reports claimed they had sought other outlets of repair, many of them costly, all of them to no avail. Each customer complained that gm was in no way helpful and had no intention of recalling vehicles, despite the fact that this is a common and dangerous defect. Upon further research, I discovered there was a small settlement concerning the issue, thus suggesting that gm acknowledges responsibility for the defect. However, the settlement only covers a small number of vehicles, and to date, no recall has been issued for this problem. I have personally contacted Chevrolet and am awaiting a reply. Additionally, I plan to take my vehicle into the dealership, but as I am in the military, I must wait until my schedule allows.

I, along with many others are experiencing major problems with the instrument panels on our Chevrolet Trailblazer. My mother traded hers in because her speedometer was going out. But my problem is much worse, my whole entire dashboard is out. My gas gauge doesn't work, my speedometer doesn't work, my oil pressure doesn't work, my thermostat doesn't work, nothing works. My cruise control acts up too.
