2005 TRAILBLAZER SPEEDO STOPS WORKING INTERMITTENTLY. SPEED WILL SHOW 40-50 MPH WHEN STOPPED OR NEVER GO ABOVE 35 MPH DURING HWY DRIVING. *TR

2005 TRAILBLAZER FUEL GAUGE OUT OF ORDER A LOT OF PEOPLE WHO HAS SAME CAR LIKE ME HAS SAME TROUBLE HAPPEN ALSO CHEVY KNOWS ABOUT THIS TROUBLE FROM FUEL PUMP AND LEVEL SENSOR TROUBLE THEY JUST WANT TO MAKE MONEY OUT OF THIS ISSUE THAT'S REALLY BAD IDEA AND MY CAR MAKE THIS TROUBLE ONLY IT WAS 40K MILE CAN YOU BELIEVE THIS. *TR

I OWN A 2005 CHEVY TRAILBLAZER EXT WITH 47,000 MILES ON IT. WHILE DRIVING ON THE HIGHWAY, I NOTICED THAT THE SPEEDOMETER READ 120MPH. MY FIRST INSTINCT WAS TO HIT THE BRAKES WHICH I DID AND THE CAR ALMOST SPUN OUT OF CONTROL. I FINALLY REALIZED THAT THE SPEEDOMETER WAS BROKEN. I CALLED THE DEALER AND THEY WILL NOT FIX IT BECAUSE THE WARRANTY HAS EXPIRED. THIS IS UNBELIEVABLE! AND IT SEEMS TO BE A COMMON PROBLEM WITH TRAILBLAZERS. I CAN'T BELIEVE THAT THERE ISN'T A RECALL FOR A DANGEROUS PROBLEM SUCH AS THIS. *TR

VEHICLE INSTRUMENT FAILURE DURING DRIVING. THE SPEEDOMETER WILL JUMP AND READ BETWEEN 15-80 MILES PER HOUR OFF, USUALLY HIGH BUT HAS READ LOW. THIS LEADS TO EITHER EXCESS OR SLOW SPEED, BOTH CONDITIONS ARE DANGEROUS IN FREEWAY AND WINTER DRIVING CONDITIONS. THERE IS A RECALL FOR THIS PROBLEM ON EVERY OTHER CHEVY VEHICLE FROM 2003 TO 2005 ON A TRUCK BASE BUT NOT THIS MODEL. THERE IS ALSO FAILURES IN BOTH VOLTAGE AND OIL PRESSURE GAUGES, EACH HAVE LED TO MAKING EMERGENCY STOPS ON THE FREEWAY TO CHECK FOR PROBLEMS. PROBLEM CAN BE CORRECTED BY TURNING CAR ON AND OFF MULTIPLE TIMES (10-20) TO RESET GAUGES. *TR

A FEW MONTHS AGO, I STOPPED TO FILL UP MY GAS TANK. WHEN I RESTARTED THE CAR, I NOTICED THE GAS GAUGE WAS READING EMPTY AND THE LIGHT WAS ON. SINCE THEN, THE GAS GAUGE IS ERRATIC AND DOES NOT READ CORRECTLY. RESEARCHING THIS ISSUE ON THE INTERNET, THERE ARE MANY OTHERS WITH THE SAME ISSUE. *TR

WHILE DRIVING DOWN THE HIGHWAY AT ABOUT 60MPH, I NOTICED THE SPEEDOMETER WAS READING 120MPH. AT THE NEXT STOP LIGHT, WITH THE VEHICLE NOT IN MOTION, THE SPEEDOMETER READ 60MPH. THE NEEDLE IS NOW ERRATIC AND JUMPS ALL OVER. LOOKING ON THE INTERNET, THERE ARE MANY OTHERS WITH THE SAME ISSUE. *TR

1. FUEL GAUGE FAILED IN OCTOBER 2006, PAID FOR REPAIR AND IT FAILED AGAIN IN NOVEMBER, 2007. 2. SPEEDOMETER JERKS AND ON OCCASION LOCKS UP OR DOES NOT RESET TO ZERO AT STOPPING. CLUSTER NEEDS REPLACEMENT. THIS HAPPENED THE FIRST TIME ON DECEMBER 16, 2008 AND HAS HAPPENED SEVERAL TIMES SINCE. *TR

MY SPEEDOMETER HAS QUIT WORKING. IT WILL REGISTER 30MPH AND I'M PROBABLY GOING 70 WHEN I'M KEEPING UP WITH THE TRAFFIC ON THE HIGHWAY. MOST OF THE TIME IT DOESN'T WORK AT ALL. THIS JUST STARTED ON THE 25TH OF DECEMBER. WE HAVE NOTICED ON THE INTERNET THAT THIS IS HAPPENING TO SEVERAL GM VEHICLES. THERE IS OTHER RECALLS ON THESE OTHER VEHICLES AND WE THINK THE 2005 TRAILBLAZER SHOULD ALSO BE INCLUDED. *TR

SPEEDOMETER NO LONGER WORKING ON MY MOTHER'S 2005 CHEVROLET TRAILBLAZER. VERY HAZARDOUS. AIR/HEAT WILL NOT BLOW IN THE FRONT VENTS AND DO NOT WORK ON SETTING NUMBER 5. *TR
