“Instrument panel keeps going out (speedometer,tach,gas,heat) reads 150 MPH while I am at a complete stop. I have to turn off the engine and turn the key on and off till it comes back down. And even this does not always work. Now the gauge for the temp. Of the car is reading that it is overheating as soon as I start driving. I have had to take it in to get it checked for several things. The car has only 42,000 miles on it. This has be going on for about a year and is getting worse!!”
