Steering Is Tight problems of the 2005 Chevrolet Monte Carlo

The steering problem was from the beginning when I bought the car used with 19,000 miles. . Very tight steering, was in warranty at the time and had it serviced. However, all they said was it was adjusted. This was the spring of 2006. Steering at this time is still very tight, and it is real bad in summer months. The car now has 39,000 approx. If my car was recalled because of this, I was never notified the speedometer after the car warms up, begins to stop working. Usually after stopping at a light, I would notice the speedometer registers below zero (0) then I know upon accelerating it will not go up even to 45 mph. . . At times it sticks to around 25 or so. Then after abruptly stopping and then going forward, it will go back to normal. This is dangerous, because I try to stay within the proper speed, according to other cars around me, but if I was to go slower than I thought to be, I could get slammed into because of not keeping up with others. I fear this. The temperature gauge is also not reading right, it usually should stay below half temp. . . It goes up above even though I have had anti freeze replaced with fresh. That too is dangerous. Other than these things, I have had little to no problems. I love the car, I just hate when there is a problem. I would like for the manufacturer to look into this, as I have noticed I am not the only one with these concerns of the exact same problem. For me, the steering is the most dangerous. Now if my car was in any recall I may not have been notified, as I moved out west for a few years, and address had changed. I am now back home. Naturally when your new / used car warranty stops, then "things" happen and still making car payments makes it hard to service the expensive parts.
