SPEEDOMETER FREQUENTLY REGISTERS THE INCORRECT SPEED OR ON OCCASIONS, NO SPEED AT ALL. SPEED INDICATED MAY BE SIGNIFICANTLY HIGHER OR LOWER THAN ACTUAL SPEED. I FREQUENTLY HAVE HAD TO RELY ON A GPS TO DETERMINE ACTUAL SPEEDS. RELYING ON THE SPEEDOMETER I HAVE SEEN THE SPEED INDICATED AT 55 MPH WHEN ACTUAL SPEED WAS ABOUT 80 MPH. SHUTTING OFF THE VEHICLE AND RESTARTING IT WILL CAUSE THE SPEEDOMETER TO RESET APPROXIMATELY 5 MPH SLOWER. THIS WILL HAVE TO BE REPEATED UNTIL THE NEEDLE REACHES 0 MPH. ONCE RESET THE SPEEDOMETER WILL TYPICALLY OPERATE NORMALLY FOR SOME RANDOM PERIOD OF TIME. *NM
