My 2005 chevy trailblazer lt speedometer has gone haywire. It will work and all of a sudden it drops to below zero. It will occasionally hover between 5-10 MPH and then drop again. Since it fails to show what your true speed is, it is a very hazardous condition.
The speedometer stopped working one random hot day. There were no resulting injuries, incidences or crashes as a result. My trailblazer has yet to have a reliable day where my speedometer works continuously.

Gas gauge, shoes it has a different amount of gas.. When turned off it can say its at 1/2 a tank, then when the engine is on it shows that car has 1 1/2 tanks of gas.
