Fuel System, Gasoline complaints
67 reportsFUEL GAUGE DOES NOT WORK ACCURATELY. I HAVE RAN OUT OF GAS TWICE BOTH TIMES THE GAUGE SHOWED THAT THERE WAS APPROX. 1/4 OF TANK REMAINING. OTHER TIMES AFTER FILLING THE GAUGE WILL DROP TO EMPTY AND THE LOW FUEL LIGHT AND CHIMES WILL COME ON WHILE DRIVING. VERY ANNOYING AND DISTRACTING. NO ACCIDENTS. *TR
OUR 2005 CHEVY TRAILBLAZER'S LOW BEAM HEADLIGHTS HAVE BEEN REPLACED, THE WIRES WERE REPLACED AND WORKED LONG ENOUGH FOR ME TO GO OUT AT NIGHT. THE FIRST NIGHT I DID GO OUT, THEY STOPPED WORKING. I WAS STUCK OUT OF TOWN WITH MY LITTLE GIRL. THANK GOODNESS I WASN'T DRIVING OR IN A PLACE WHERE I DIDN'T HAVE CELL PHONE SERVICE(WHI…

OUR 2005 CHEVY TRAILBLAZER'S LOW BEAM HEADLIGHTS HAVE BEEN REPLACED, THE WIRES WERE REPLACED AND WORKED LONG ENOUGH FOR ME TO GO OUT AT NIGHT. THE FIRST NIGHT I DID GO OUT, THEY STOPPED WORKING. I WAS STUCK OUT OF TOWN WITH MY LITTLE GIRL. THANK GOODNESS I WASN'T DRIVING OR IN A PLACE WHERE I DIDN'T HAVE CELL PHONE SERVICE(WHICH I DON'T HAVE CLOSE TO MY HOME). ALSO, OUR FUEL GAUGE DOESN'T WORK. WE'VE HAD IT REPAIRED AND IT WORKED FOR A SHORT PERIOD AS WELL, BUT DOESN'T WORK ANY LONGER. APPARENTLY, THESE TWO ISSUES ARE COMMON PROBLEMS THAT CHEVROLET NEEDS TO ADDRESS. A RECALL WOULD BE NICE. I HAVE TWO MORE PAYMENTS AND I DO NOT WANT TO BUY A NEW VEHICLE. NOR WOULD I FEEL COMFORTABLE SELLING THIS ONE AS IT IS. *TR

I HAVE A 2005 CHEVY TRAILBLAZER. MY FUEL LEVEL SENSOR IS NOT ACCURATE. I NEVER KNOW HOW MUCH FUEL I REALLY HAVE. I CAN TRY TO FILL IT UP AND IT READS THAT I AM EMPTY. *TR
ON JULY 3, 2010 I BOUGHT A USED 2005 CHEVY TRAILBLAZER. THE VEHICLE HAD NOT BEEN IN MY POSSESSION FOR A FEW DAYS WHEN I NOTICED THAT THE GAS MEASUREMENT COULD NOT BE RIGHT. I REFILLED IT SEVERAL TIMES. THEN, AFTER REFILL, IT STILL SHOWED ZERO. IT IS EXTREMELY DIFFICULT, INCONVENIENT AND DANGEROUS TO HAVE TO COUNT MILES, AS A …

ON JULY 3, 2010 I BOUGHT A USED 2005 CHEVY TRAILBLAZER. THE VEHICLE HAD NOT BEEN IN MY POSSESSION FOR A FEW DAYS WHEN I NOTICED THAT THE GAS MEASUREMENT COULD NOT BE RIGHT. I REFILLED IT SEVERAL TIMES. THEN, AFTER REFILL, IT STILL SHOWED ZERO. IT IS EXTREMELY DIFFICULT, INCONVENIENT AND DANGEROUS TO HAVE TO COUNT MILES, AS A PARENT WITH A SMALL CHILD ITS ALMOST IMPOSSIBLE. THE CAR RAN OUT OF GAS ON THE WAY TO A FAMILY FUNERAL. FORTUNATELY I WAS ABLE TO GET OVER OFF OF THE HIGHWAY. THIS IS AN EXTREMELY HAZARDOUS AND IT SEEMS THAT GM SHOULD ISSUE A RECALL FOR PRODUCT DEFECT. ON A HIGHWAY SITUATION, THE ACCIDENT ENSUING FROM A STALLED CAR COULD BE FATAL. *TR

I AM EXPERIENCING A PROBLEM THAT IS INVOLVED IN A CURRENT ODI INVESTIGATION. MY 2005 CHEVY TRAILBLAZER HAS INTERMITTENT FUEL READING FAILURES READING INCORRECTLY. THIS HAS BEEN ONGOING FOR APPROXIMATELY 7 MONTHS BUT HAS BEEN PROGRESSIVELY BECOMING MORE FREQUENT AND ALSO OCCURRING RIGHT NOW. RESEARCHING THIS PROBLEM ONLINE I DISCOVERED OVER ONE HUNDRED FORUM POSTINGS OF OWNERS WITH THE SAME PROBLEM AND ALSO FOUND OUT ABOUT ODI DP 10-001. MY PROBLEM IS CURRENT AND ONGOING, FURTHER MORE IS AVAILABLE FOR INSPECTION FOR THE OPEN INVESTIGATION IF REQUESTED. *TR

2005 CHEVY TRAILBLAZER FUEL GAUGE FLUCXUATING EVEN WHEN THERE IS A FULL TANK OF GAS. THIS CAN CAUSE THE VEHICLE TO STOP, STALL, CAUSE AN ACCIDENT. CAUSING EXTRA AMOUNTS OF MONEY TO PUT IN THE TANK WHEN NOT REALLY NECESSARY. THERE HAVE BEEN MORE THAN ENOUGH COMPLAINTS REGARDING THIS ISSUE, AND SHOULD NOT TAKE SOMEONE GETTING HURT IN ORDER FOR THE RECALL TO BE PASSED. YOU EXPECT US TO PAY $800-900 TO HAVE IT REPAIRED BUT WHEN IT IS RECALLED, IT WILL TAKE MONTHS TO EVEN GET REFUNDED FOR THE $$ WE PAID OUT FOR THE PROBLEM. I DIDN'T HAVE AN ACCIDENT, HOWEVER, I DID HAVE MY SMALL CHILDREN IN THE CAR WHEN IT STOPPED IN 90 DEGREE WEATHER IN CHARLOTTE NC. WE HAD TO WAIT FOR OVER AN HOUR FOR HELP TO ARRIVE. *TR

THE FUEL GAUGE IS INACCURATE - RANDOMLY FLUCTUATES FROM MOMENT TO MOMENT FROM EMPTY/LOW FUEL LIGHT ON, FULL, TO SOMEWHERE INBETWEEN. THIS HAS BEEN ONGOING SINCE APPROXIMATELY APRIL, 2010. CHECK ENGINE LIGHT IS ON, AND ONSTAR INDICATES THAT AN ELECTRICAL PROBLEM IS PRESENT. VEHICLE WILL NOT PASS EMISSIONS TESTING WITH CHECK ENGINE LIGHT ON. SAFETY CONCERN IF VEHICLE RUNS OUT OF GAS - WE ARE FORCED TO DRIVE IT NOW FOR ONLY A FEW HUNDRED MILES BETWEEN FILL-UPS TO ENSURE ADEQUATE FUEL IN TANK. WE HAVE RESEARCHED POTENTIAL REPAIRS, AND THEY WILL COST APPROXIMATELY $600-$800 TO FIX. *TR
