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

THE SPEEDOMETER STARTED STICKING AND THEN IT GOT STUCK ON 160 MPH. IT WILL NOT MOVE. IT IS VERY DANGEROUS TO DRIVE THE VEHICLE BECAUSE YOU HAVE NO IDEA HOW FAST OR SLOW THAT YOU ARE GOING AND YOU POSE A RISK TO OTHERS AS WELL. CHEVROLET WOULD NOT COVER IT UNDER THEIR RECALL EVEN THOUGH THEY HAVE ALREADY RECALLED 2003-2004 TRAILBLAZERS FOR THE SAME PROBLEM. MY VEHICLE HAS 59000 MILES ON IT .THE REPAIR FOR THE INSTRUMENT PANEL CLUSTER WILL COST OVER 900 DOLLARS HERE IN GERMANY WHERE WE ARE STATIONED WITH THE US MILITARY. WE CAN NOT AFFORD TO REPAIR IT YET. *TR

WHILE DRIVING ON THE HIGHWAY, THE REAR BRAKE LIGHT ACCESSORY FELL OFF MY 2005 CHEVROLET TRAILBLAZER EXT. WHILE THE VEHICLE WAS IN MOTION. THERE WAS NO PRIOR INDICATION THAT THE PIECE WAS LOOSE. THE PIECE, FORTUNATELY, REMAINED ATTACHED TO THE VEHICLE WHILE SLAMMING AGAINST MY REAR WINDOW. I AM CONCERNED THAT THE MANUFACTURER OF THIS VEHICLE IS NOT PROPERLY SECURING THE REAR BRAKE LIGHT PIECE AND ENDANGERING MY FAMILY AS WELL AS OTHER MOTORISTS. WHEN I TRIED TO RECTIFY WITH THE DEALERSHIPS SERVICE SHOP, THEY CLAIMED THAT ICE CAN CAUSE THIS PROBLEM, CITING THAT THEY HAD SEEN THIS HAPPEN A COUPLE OF TIMES PRIOR, AND REFUSED TO TAKE RESPONSIBILITY FOR CORRECTING THE PROBLEM, CLAIMING THAT IT WAS DUE TO AN ACT OF NATURE AND PERHAPS I COULD FILE A CLAIM WITH MY AUTOMOBILE INSURANCE PROVIDER. *TR

GAS GAUGE FAILED AT 40,000 MILES. THE NEEDLE WILL NOT MOVE OFF OF "E". FOR A SHORT TIME IT WOULD ACTUALLY READ 1/4 FULL WHEN THE TANK WAS FULL NOW IT DOESN'T MOVE. THE WARNING DING GOES OFF PERIODICALLY. IN ADDITION TO THE GAS GAUGE PROBLEM THE BLOWER ON THE HEATER/AC NO LONGER WORKS ON THE HIGH SETTING. THIS CAR IS BARELY TWO YEARS OLD, THERE IS NO EXCUSE FOR POOR QUALITY IN AMERICAN MADE CAR'S! OF COURSE THESE ITEMS FAILED AFTER THE WARRANTY EXPIRED. AT 15,000 MILES THE ELECTRICAL COMPONENT THAT CONTROLS THE TURN SIGNALS FAILED. ENGAGED THE TURN SIGNAL TO TURN RIGHT AND THE LEFT TURN SIGNAL CAME ON.....OH WELL, AT LEAST THAT WAS UNDER WARRANTY. *TR

I PARKED THE 2005 TRAILBLAZER IN THE GARAGE AFTER A SHORT TRIP TO PICK UP A NEIGHBORS CHILD. TWO HOURS LATER WHEN I WENT TO START MY CAR TO TAKE THE CHILD HOME, MY KEY WOULD NOT TURN. STEERING WHEEL WAS NOT LOCKED ( IT COULD BE TURNED AND TURN THE WHEELS) TRANS WAS LOCKED. I READ ON ONLINE FORUMS THAT OTHERS HAVE HAD ISSUES LIKE THIS, ONE GUY SAID THAT HE WAS ABLE TO PULL BACK ON HIS SHIFTER AND TURN THE KEY AT THE SAME TIME. THIS DID NOT WORK FOR ME AS THE TRANS SHIFTER WAS LOCKED. RESULT, TOW, AND REPLACE SWITCH. *TR

TWO TIRES FAILED WITHIN A WEEK WITH SIMILAR CIRCUMSTANCES. THE FIRST TIRE FAILURE WAS LESS DRAMATIC THAN THE SECOND DUE TO THE FACT THAT IT OCCURRED AT NIGHT WHEN TEMPERATURES WERE COOLER AND VEHICLE STOPS WERE MORE FREQUENT. THE SECOND FAILURE WAS CATASTROPHIC. THE SIDEWALLS COMPLETELY SEPARATED FROM THE TREAD ON A VERY BUSY HIGHWAY. AFTER THE FIRST TIRE FAILURE I HAD THE TIRES ALIGNED, BALANCED AND PRESSURE CHECKED BY A GM TECHNICIAN. THE SERVICE MANAGER AT THE GM DEALER CLEARLY TOLD ME THAT THE TWO REMAINING TIRES WERE IN GOOD SHAPE AND HAD SEVERAL THOUSAND MILES ON THEM BEFORE I HAD TO WORRY ABOUT CHANGING THEM. FOUR DAYS LATER THE TIRE FAILED COMPLETELY. AFTER THE INCIDENT I CALLED BACK TO THE GM DEALER TO VERIFY THEIR PROCESS FOR TIRE ALIGNMENT. THEY INFORMED ME THAT THE TIRES WERE INDEED VERIFIED TO BE AT 35PSI, THE FACTORY RECOMMENDED LEVEL. I RETAINED THE FAILED TIRE FOR FUTURE USE. THE TIRES WERE CONTINENTAL CONTI-TRAC P245/65/R17 WITH A DOT NUMBER OF HW8T BL5 0305. A SIMILAR REPORT HAS BEEN FILED WITH THE NHTSA. *TR
