NHTSA Complaint #11078560 — 2003 CHEVROLET TRAILBLAZER

FOR THE LAST 3 YEARS, EVERY PART OF MY INSTRUMENT PANEL SEEMS TO WORK INTERMITTENTLY. AT TIMES WHILE DRIVING, THE SPEEDOMETER WILL SHOW ME DOING 40 MPH OVER MY ACTUAL SPEED, OR WILL SHOW ME DOING 120 WHILE I AM SITTING STILL. THE OIL PRESSURE WILL SOMETIMES SHOW THAT THERE IS NO PRESSURE AT ALL, OR THE TEMP IS AS FAR AS IT CAN GO ON THE HOT SIDE. ALL OF THESE ISSUES DISAPPEAR AFTER A WHILE, AND THEN FUNCTION NORMALLY. THEY DO NOT SEEM TO BE TIED TOGETHER, BECAUSE AT TIMES SEVERAL INSTRUMENTS ARE WORKING FINE, BUT 2 OTHERS ARE NOT.
