I HAVE A 2005 TRAILBLAZER EXT PURCHASED NEW IN JULY 05. RECENTLY WHILE DRIVING, THE CAR HAD REDUCED ENGINE POWER, THE CHECK ENGINE LIGHT THEN CAME ON THEN MY CAR JUST SHUT OFF. IT STARTED BACK UP AFTER PULLING OFF THE ROAD BUT HAD TO ENDURE THIS THE ENTIRE TIME WHILE DRIVING HOME. WHEN I TOOK IT IN FOR DIAGNOSIS I WAS TOLD THE ACCELERATOR PEDAL SENSOR NEEDED TO BE REPAIRED AFTER HAVING THAT REPAIRED I DROVE HOME AND THE SAME THING HAPPENED WITH THE CHECK ENGINE LIGHT AND THE CAR SHUTTING OFF WHILE DRIVING. WHEN I TOOK IT BACK AGAIN THEY NOTICED AN ADDITIONAL PROBLEM " THE FUEL LEVEL SENSOR WIRING WAS CHAFFING ON FUEL PUMP GROUND TERMINAL" OR IN LAYMAN'S TERM THE WIRE WAS SITTING IN FUEL SO THEY HAD TO REMOVE THE FUEL TANK AND REROUTE THE WIRES. THIS SOUNDS VERY DANGEROUS AND IF THIS IS HAPPENING PLEASE REPORT IT. THERE ARE TSB REPORTS ON THE ISSUE WITH THE ACCELERATOR PEDAL BUT GM HAS NOT ISSUED A RECALL ON THIS. THE QUESTION IS WHY NOT? I HAVE ALSO HAD TO HAVE THE OUTPUT SHAFT SEAL ON THE TRANSMISSION REPLACED LAST YEAR AND AGAIN THIS YEAR. NOT VERY HAPPY WITH THIS VEHICLE. IN MY OPINION THESE ARE VEHICLE DEFECTS NOT PROBLEMS YOU SHOULD BE HAVING WITH THE NORMAL MAINTENANCE ISSUES. GM NEEDS TO ISSUE RECALLS TO HAVE THESE ISSUES RESOLVED. OH IN ADDITION TO THE OTHER PROBLEMS I ALSO JUST HAD TO HAVE THE THERMOSTAT REPLACED IN EARLY JUNE. *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
GAS GAUGE STAYS ON EMPTY AND THE BELL RINGS EVEN WHEN FULL. *TR
THE GAS GAGE IN MY 2005 CHEVROLET TRAILBLAZER HAS BEEN REPLACED 2 TIMES AND IT'S OUT AGAIN. I'VE BEEN TOLD BY QUITE A FEW PEOPLE THAT THIS IS A VERY COMMON PROBLEM WITH CHEVROLET. *TR
ON TODAY I WENT TO FILL UP MY TANK DUE TO HURRICANE IKE. BEFORE I WENT TO THE GAS STATION ALL GAUGES WERE FINE BUT WHEN I RETURNED TO WORK I NOTICED THAT THE GAS GAUGE WAS ONE WITH THE LIGHT LIT. I TURNED OFF THE ENGINE AND TURNED IT BACK ON AND IT STAYED THE SAME. THIS SHOULD BE FIXED AND COVERED SOME TYPE OF RECALL. *TR
THE FUEL GAUGE DOES NOT ACCURATELY REPRESENT THE TRUE AMOUNT OF GAS IN THE TANK. AFTER TALKING WITH CHEVROLET OWNERS AND DOING RESEARCH ON THIS ISSUE, IT SEEMS TO BE A COMMON THEME. THE GAS GAUGE INDICATES THAT THE VEHICLE'S GAS TANK IS EITHER EMPTY AFTER BEING RECENTLY FILLED OR ONLY SLIGHTLY ABOVE THE "E" ON THE GAS GAUGE. …

THE FUEL GAUGE DOES NOT ACCURATELY REPRESENT THE TRUE AMOUNT OF GAS IN THE TANK. AFTER TALKING WITH CHEVROLET OWNERS AND DOING RESEARCH ON THIS ISSUE, IT SEEMS TO BE A COMMON THEME. THE GAS GAUGE INDICATES THAT THE VEHICLE'S GAS TANK IS EITHER EMPTY AFTER BEING RECENTLY FILLED OR ONLY SLIGHTLY ABOVE THE "E" ON THE GAS GAUGE. IT TAKES ABOUT TWO DAYS OR 12 STATUTORY MILES BEFORE THE GAS GAUGE BEGINS TO DISPLAY AN ACCURATE READING, IF THAT IS EVEN TRUE! ON 30 APRIL 2008, DURING A FAMILY ROAD TRIP, THE GAS GAUGE BEGAN TO DISPLAY THAT THE GAS TANK WAS A QUARTER FULL AFTER BEING FILLED. AFTER DRIVING ANOTHER HOUR AND A HALF, THE GAUGE READ EMPTY AND THEN WENT BACK TO A QUARTER FULL. I GUESS CHEVROLET DOESN'T CARE ABOUT THE QUALITY OF THEIR WORK, JUST ITS QUANTITY OF SALES. *TR
