NHTSA Complaint #10343613 — 2005 CHEVROLET TRAILBLAZER

TRAILBLAZER WAS MAKING ROARING NOISE WHEN FIRST STARTING UP AND TOOK ABOUT 2 MINUTES FOR IT TO RUN NORMAL, VOLTAGE METER FLUCTUATES AS WELL AS THE LIGHTS DIMMING INTERMITTENTLY DURING THIS TIME. THIS STARTED HAPPENING ABOUT 3 WEEKS AGO. WHEN FIRST TAKING OFF AFTER BEING STOPPED, ENGINE ACCELERATES UNEXPECTEDLY. IT JUMPS, AND I HAVE TO HIT THE BRAKES. IT HAS HAD THIS PROBLEM SINCE I HAVE OWNED IT (SINCE JAN '09). THE LAST COUPLE OF DAYS IF THE RADIO IS LEFT ON, IT DOES NOT AUTOMATICALLY SHUT OFF LIKE IT IS SUPPOSED TO WHEN YOU SHUT THE DOOR. THE PASSENGER SIDE WORKS. JUST HAD CLUTCH FAN AND WATER PUMP REPLACED AND THE MECHANIC SAYS THAT IT IS A COMMON PROBLEM WITH THESE VEHICLES. AFTER HAVING THAT DONE, IT STILL MAKES A ROARING NOISE FOR THE FIRST FIVE TO TEN MINUTES OF DRIVING. GOING TO HAVE ANOTHER DIAGNOSTIC ON IT TO SEE WHAT IS WRONG WITH IT. THE SUV IS A 2005 CHEVROLET TRAILBLAZER LS, 4WD, 6 CYLINDER MOTOR AND HAS ABOUT 88,000 MILES ON IT. *TR
