2006 CHEVROLET TRAILBLAZER EXT Fuel System, Gasoline Problems

I WAS DRIVING THE TRUCK AND THE FUEL GAUGE WAS READING THAT THERE WAS GAS IN THE TANK. THE VEHICLE DIED CAUSING LOSS OF POWER STEERING AND POWER BRAKES. I WAS ABLE TO PULL THE TRUCK TO THE SIDE OF THE ROAD WITH GREAT EFFORT. HAD MY WIFE OR TEENAGE DAUGHTER BEEN DRIVING THE OUTCOME MIGHT HAD BEEN VERY DIFFERENT.AFTER FILLING THE GAS TANK THE GAUGE WENT TO E AND NEVER WORKED PROPERLY AFTERWARDS. *TR

Mileage: 90,000

I WAS ON A TRIP WHEN I HAD STOPPED TO FUEL UP MY TANK BECAUSE IT WAD CLOSE TO EMPTY SO ONCE I FUELED IT UP TO FULL AND TURNED MY CAR BACK ON FOR A SECOND IT SHOWED FULL TANK THEN JUST STROLLED TO EMPTY AND AFTER FEE MINUTES WENT BACK TO FULL. COUPLE DAYS LATER THE GAUGE JUST STARTED GOING CRAZY AND SHOWING ALL KINDS OF LEVELS OF THE FUEL TANK. NOW IT ONLY STAYS ON EMPTY WITH THE YELLOW LIGHT ON. BUT BEFORE THIS ALL HAPPENED MY OIL PRESSURE SENSOR STOPPED WORKING. ITS FRUSTRATING AND I'VE BEEN LEFT WITHOUT GAS ON MIDDLE OF ROAD A FEW TIMES. *TR

Mileage: 143,000

WE HAVE HAD THIS VEHICLE IN THE CHEVROLET DEALER SHOP SEVERAL TIMES OVER THE PAST FEW YEARS. TWICE IT WAS SENT WITH THE ENGINE LIGHT ON AND CAME BACK TO US WITH THE SAME LIGHT STILL ON. AS A MATTER OF FACT, THE LAST ISSUE THAT WAS REPAIRED HAD TO BE FIXED TWO MORE TIMES BY MY HUSBAND. THE DEALER REPAIRMAN TOLD MY HUSBAND WHAT TO DO IN CASE IT HAPPENED AGAIN. $800 LATER, IT HAS HAPPENED TWICE. ALSO, THE LAST TIME IT CAME BACK FROM THE DEALER, THE GAS GAUGE HAD STOPPED WORKING. I HAVE BEEN TRACKING MILES TO KEEP FROM RUNNING OUT OF GAS; HOWEVER, I HAVE STILL RUN OUT OF GAS FIVE TIMES! AS A BUSY MOM, KEEPING UP WITH GALLONS AND MILEAGE BECOMES TOO MUCH OF A HASSLE. I'M DRIVING (STOP AND GO) 300+ MILES A WEEK. WE HAVEN'T TAKEN IT BACK TO THE DEALER BECAUSE OUR INCOME HAS SUFFERED A LOSS OVER THE PAST SIX MONTHS; THEREFORE, WE HAVE BEEN DEALING WITH THE PROBLEM. THIS IS OBVIOUSLY A PROBLEM WITH A LOT OF 2006 TRAILBLAZERS. I AM ASKING FOR HELP BECAUSE I'M TIRED OF RUNNING OUT OF GAS. *TR

IN SUMMER OF 2011 I HAD THE FIRST OCCURRENCE OF THE FUEL GAUGE INCORRECTLY SHOWING THE FUEL LEVEL. THIS WENT ON FOR SEVERAL WEEKS AND THEN WENT BACK TO NORMAL FOR A FEW MONTHS. AS OF JANUARY OF THIS YEAR, I HAVE THE ISSUE AGAIN , ONLY THIS TIME THE FUEL GAUGE IS DOWN COMPLETELY AND SHOWING EMPTY 90% OF THE TIME. I HAVE CONTACTED GM AND THEY ARE AWARE OF THE ISSUE AND OFFER 50% DISCOUNT ON REPAIR. THIS SHOULD BE A RECALL AS THIS IS A SERIOUS ISSUE AND OBVIOUSLY AFFECTING A VERY LARGE NUMBER OF OWNERS OF THIS MODEL OF CHEVROLET. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER EXT. THE CONTACT STATED THAT THE FUEL GAUGE CONSTANTLY DISPLAYED INACCURATE READINGS. THE FAILURE PROGRESSED UNTIL THE FUEL GAUGE CONSTANTLY DISPLAYED A READING OF EMPTY. THE VEHICLE WAS NOT TAKEN TO HAVE THE FAILURE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 104,000.

Mileage: 104,000

THE FUEL GAUGE STOPPED WORKING AND WE WERE TOLD TO TAKE IT TO OUR LOCAL CHEVY. DEALER, WHERE WE WERE TOLD THAT CHEVY WOULD FIX THIS PROBLEM BY PAYING HALF THE COST TO REPAIR THE PROBLEM, THIS IS SUCH A RIP OFF ,THERE PROBLEM YET WE HAVE TO PAY HALF TO FIX IT ,NOT RIGHT. I HAVE GONE TO MANY WEB SITES AND THIS IS A VERYCOMMON PROBLEM WITH CHEVY TRAILBLAZERS,ALL YEARS . THEY SHOULD BE RECALLED AND CHEVY. MADE TO FIX THERE PROBLEM FOR NOTHING. *TR

Mileage: 27,000

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER EXT. THE CONTACT STATED THAT THE FUEL GAUGE WOULD READ INACCURATE FUEL LEVELS. THE DEALER AND THE MANUFACTURER WERE NOTIFIED OF THE FAILURE AND OFFERED TO ASSIST WITH THE COST OF REPAIRS. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 49,000 AND THE CURRENT MILEAGE WAS 56,000. THE VIN WAS UNAVAILABLE.

Mileage: 49,000

I RAN OUT OF GAS ON EXPRESSWAY ON WAY HOME FROM WORK WHILE GAUGE SHOWED 1/4 TANK. THIS HAPPENED AGAIN MONTHS LATER WITH TANK SHOWING JUST UNDER 1/4 TANK. GAUGE AROUND THE TIME OF FIRST INCIDENT STARTED BOUNCING AROUND OFF AND ON AT ANY READING WHILE SUV WAS RUNNING. IT WOULD GO FROM EMPTY TO 1/2 A TANK AND BOUNCE AROUND BACK AND FORTH EVENTUALLY STOPPING AT A RANDOM AMOUNT. THE GAUGE WOULD GO TO EMPTY WHEN IT WAS FULL UNTIL IT WAS DRIVEN ENOUGH THAT I WAS DOWN TO AROUND 3/4 OF A TANK THEN IT WOULD GIVE THE CORRECT READING UNTIL GUESSING AROUND 1/4 OF A TANK WHEN THE INCIDENTS HAPPENED WITH ME RUNNING OUT OF GAS. A FEW MONTHS LATER THE GAUGE COMPLETELY QUIT WORKING AND HAS YET TO WORK SINCE THEN. I STARTED RESEARCHING ONLINE ABOUT THE GAUGE AND FOUND MULTIPLE INCIDENTS WITH SAME YEAR AND MAKE AND MANY PEOPLE STATING THEY PAID OVER $700 TO HAVE REPAIRS DONE AND MULTIPLE PEOPLE STATING THEY HAD IT FAIL AGAIN. SINCE READING THOSE REMARKS I HAVE YET TO HAVE IT REPAIRED AND HAVE HAD TO KEEP TRACK OF MY MILEAGE SO THAT I DON'T RUN OUT OF FUEL AGAIN. *TR

Mileage: 80,000

FUEL GAUGE STOP WORKING AND OUT OF FUEL LIGHT STAYS ON EVEN WITH A FULL TANK OF FUEL. *TR

Mileage: 92,650

THE BEARINGS ON THE ALTERNATOR ARE WEARING AND NEED TO BE REPLACED, THE VEHICLE ONLY HAS 29,000 MILES AND ACCORDING TO MY MECHANIC THEY SHOULD NOT BE WORN THIS EARLY AND SHOULD BE REPLACED AS SOON AS POSSIBLE; THIS IS DEFINITELY A SAFETY ISSUE AND A FAULTY PART THAT I SHOULD NOT HAVE TO PAY TO HAVE REPLACED. THE FUEL LEVEL INDICATOR HAS STOPPED WORKING OVER 2.5 YEARS AGO. I DID RECEIVE A LETTER SAYING THAT THE PART MAY WEAR OUT PREMATURELY AND THEY ARE WILLING TO PAY 50% OF THE REPLACEMENT BUT IF IT WEARS OUT PREMATURELY THEN THE PART IS FAULTY AND I SHOULD NOT HAVE TO PAY TO REPLACE THE PART. THE BACKUP LIGHT PANEL IS BAD, I TRIED TO REPLACE THE BULB BUT THE PROBLEM LIES WITH THE PANEL, FAULTY PART AGAIN. *TR

FUEL SENSOR FAILURE, DOES NOT READ TRUE FUEL TANK LEVEL. GENERALLY WHEN FULL READS EMPTY THEN AS TANK DECREASES GAUGE MAY READ CORRECT. *TR

I PURCHASED A 2006 TRAILBLAZER IN 2006. IT RAN GREAT UNTIL ABOUT 36000 MILES WHEN THE FUEL GAUGE BEGAN ACTING UP. AT ABOUT 36500 MILE, THE GAUGE QUIT WORKING AND I TOOK IT TO THE DEALER AND WAS TOLD IT WOULD BE 800.00 TO REPAIR. I HAVE TO TRY TO GAUGE HOW MANY MILES I CAN GET ON A TANK OF GAS. IT HAS BEEN LIKE THIS FOR OVER A YEAR AND A HALF. I HAVE RUN OUT OF GAS TWICE, ONCE IN THE SUMMER WITH TWO SMALL CHILDREN IN THE CAR AND ONCE IN THE WINTER. THIS IS A VERY DANGEROUS SITUATION AND NEEDS TO BE ADDRESSED BY GM. I UNDERSTAND THEY SAY THEY WILL DISCOUNT THE REPAIR 50 %, BUT THIS IS NOT SOMETHING THE CONSUMER HAS CONTROL OVER. WE CAN NOT CAUSE THE DAMAGE AS IT IS INSIDE THE GAS TANK. WE HAVE 2 GM PRODUCTS AND IF IT IS NOT REMEDIED THEY MAY BE OUR LAST. MAYBE IT IS TIME FOR SOMEONE TO FILE A CLASS ACTION SUIT. AND WE MIGHT ALL END UP WITH NEW VEHICLES. I WOULD THINK THE RECALL WOULD BE LESS EXPENSIVE. *KB

Mileage: 36,500

WENT TO GET GAS FOR MY 2005 CHEVY TRAILBLAZER. WHEN I DID I GOT BACK IN THE VEHICLE AND STARTED THE CAR. THE EMPTY SENSOR FOR THE GAS DINGED ALERTING ME THAT I WAS ALMOST OUT OF GAS AND WOULDN'T GO ABOVE THE EMPTY LEVEL. IT NOW PLAYS TRICKS RANGING FROM FULL TO EMPTY AT ANY GIVEN POINT IT CAN BE FULL 1 TIME THEN GO TO 1/4 FULL THEN BACK UP TO FULL IN 1 TRIP TO THE STORE. IT APPEARS THIS IS A COMMON ISSUE FROM RESEARCH ON THE INTERNET. *TR

Mileage: 77,691

THE FUEL LEVEL SENSOR WENT OUT AND SAID THERE WAS NO GAS IN THE CAR WHEN THERE WAS WHEN IT WAS STILL PRETTY NEW. SOMETIME DURING THE TRIP, IT WOULD SAY IT WAS FULL WHEN PREVIOUSLY IT SAID IT WAS NEAR EMPTY. UNFORTUNATELY FOR ME I WAS TRAVELING ON THE INTERSTATE AND I HAD NO IDEA HOW MUCH GAS I HAD OR HOW MUCH TO PUT IN THE CAR. I COULD HAVE EASILY BEEN STRANDED ALONE ON THE INTERSTATE AND PUT IN A VERY DANGEROUS SITUATION. I ALSO COULD NOT RENEW MY LICENSE TAG WITHOUT GETTING IT REPAIRED IN THE STATE OF GA. I THOUGHT THE $400 EXPENSE AFTER HAVING A NEW CAR FOR LESS THAN 2 YEARS FOR AN ELECTRICAL ISSUE WAS RIDICULOUSLY UNRELIABLE QUALITY. *TR

Mileage: 52,000

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER EXT. THE CONTACT STATED THAT WHEN DRIVING AT VARIOUS SPEEDS THE VEHICLE WOULD STALL. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY ADVISED THE CONTACT THAT THE EVAPORATOR VENT FAILED AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS CONTACTED AND THEY OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 90,000. UPDATED 10/12/11 *BF UPDATED 3/30/12 *CN

FUEL GAUGE SHOWED I WAS EMPTY AFTER FILLING UP THE CAR. THE GAUGE NOW READS ERRATICALLY AND DOES NOT SHOW THE PROPER AMOUNT OF FUEL IN THE TANK. MY WIFE IS THE PRIMARY DRIVER OF THIS CAR AND I FEAR THAT SHE WILL RUN OUT OF GAS DUE TO THE "FAILURE" OF THE GAUGE. WE ARE DOING OUR BEST TO DRIVE BY MILEAGE BUT OUR MPG VARIES QUITE A BIT DEPENDING ON OUR DRIVING SITUATION. JUST RECEIVED A LETTER FROM GM ADVISING THEY WILL PAY 50% OF REPAIR COSTS. HOWEVER, I FEEL THAT THIS SAFETY RELATED ITEM FAILURE SHOULD BE COVERED ENTIRELY BY GM VIA A RECALL. ANYTHING YOU CAN DO TO HELP WOULD BE APPRECIATED.

GAS GAUGE BECAME VERY ERRATIC. FINALLY DIDN'T REGISTER AT ALL. CHECK ENGINE LIGHT CAME ON WHILE OUT OF TOWN. TOOK THE CAR TO A MERLIN AUTOMOTIVE FOR REPAIR. SPENT HUNDREDS OF DOLLARS AND THE LIGHT WOULD NOT GO OFF. MASS AIR FLOW METER, PLUGS, FUEL RAIL, THROTTLE POSITION SENSOR, FUEL INJECTORS. THEY EVEN CALLED IN A CHEVY TECHNICIAN WHO COULD NOT FIGURE IT OUT. WHEN I RETURNED HOME I TOOK IT TO MY LOCAL REPAIR SHOP WHERE THEY DROPPED THE TANK AND REPLACED THE SENDING UNIT. HUNDREDS OF DOLLARS IN EXPENSES. THEN THE HEATING FAN SWITCH STARTED SMOKING AND HAD TO BE REPLACED AS IT HAD MELTED AND NOTHING WORKED . ALSO, EVERY DOOR RUSTED THROUGH AT THE BOTTOM INCLUDING THE REAR HATCH. DEALERS' RESPONSE:WELCOME TO WISCONSIN. I SPENT $700 TO HAVE THE RUST CLEANED UP. *TR

Mileage: 99,000

AT 30,000 MILES THE FUEL GAUGE ON MY 206 TRAILBLAZER STARTED GIVING WRONG READINGS. IT NEVER HAS THE CORRECT AMOUNT ON THE GAUGE. IT HAS CAUSED ME TO RUN OUT OF FUEL ON SEVERAL OCCASIONS. I HAVE BEEN LUCKY TO NOT CAUSE AN ACCIDENT. AS THE MILEAGE CAN CHANGE BASED ON DRIVING I HAVE TO JUST FILL UP EVERY 200 MILE TO BE SAFE. GM HAS TOLD ME THIS REPAIR IS NOT COVERED UNDER ANY WARRANTY AND WOULD COST ABOUT $1000.00 FOR THEM TO REPLACE THE FUEL SENDING UNIT. *TR

BOUGHT 2006 CHEVY TRAILBLAZER EXT USED FROM THE DEALER IN 2009 FOR COMMUTE TO AND FROM WORK. UPON REACHING 63,000 MILES BEGAN TO HAVE PROBLEMS WITH FUEL GAUGE READING HALF FULL THEM EMPTY EVEN AFTER JUST HAVING FILLED UP THE TANK AT THE STATION. AS A RESULT CHECK ENGINE LIGHT ACTIVATED AND WHEN IT CAME TIME TO INSPECT THE VEHICLE NO ONE AT THE LOCAL DEALERSHIPS WERE WILLING TO DROP THE GAS TANK AND FIX THE PROBLEM SO I COULD PASS INSPECTION. PENNA STATE EMISSIONS WOULD NOT PASS THE VEHICLE UNTIL THE FUEL SYSTEM WAS REPAIRED, HENCE CANNOT PASS INSPECTION. I WILL NO LONGER USE THE VEHICLE ON LONG TRIPS WHERE I HAVE TO GUESS HOW MUCH GAS I HAVE IN THE TANK, OR TAKE IT ON BUSY HIGHWAYS LIKE 95 OR 83 NEAR WASHINGTON CLOSE TO WHERE I LIVE. PROBLEM DESCRIPTION SEEMS TO BE CONSISENT WITH THIS MODEL YEAR. WHILE I WAS WILLING AND ABLE TO PAY FOR MY REPAIR THE FIRST TIME, IT IS NOT MY RESPONSIBILITY TO ACCOUNT FOR A SHODDY PRODUCT. GM HAS ALREADY ATTEMPTED TO CONTACT ME AND COVER 50% OF THE REPAIR VIA MAIL. THIS IS AN INSULT TO MY INTELLIGENCE AND I SHOULD NOT HAVE TO FORK OVER ONE RED CENT TO GET THIS FIXED GIVEN THE MASSIVE AMOUNT OF COMPLAINTS ABOUT THE SAME PROBLEM ON THE SAME VEHICLE. IGNITION SWITCH ALSO FAILED AT 60,000 MILES. YET ANOTHER ITEM I AM FINDING IS A RECURRING PROBLEM WITH THIS MODEL, MAKE AND YEAR. *TR

VEHICLE BOUGHT AUG 2010 WITH 76, 014 MILES ON IT. ABOUT ONE MONTH AFTER THE PURCHASE THE GAS GAUGE STARTING ACTING ERRATIC. ( COULD HAVE BEEN THAT WAY WHEN WE BOUGHT IT BUT DIDN'T NOTICE.) WHEN YOU WOULD FILL IT UP IT WOULD STILL READ E UNTIL YOU DROVE ABOUT 50 MILES OFF FROM IT THEN IT WOULD BOUNCE AROUND SOMETIMES READING CORRECT OTHER TIMES NOT. I RAN OUT OF GAS ON I-69 ONE TIME FORTUNATELY FOR ME NO ONE WAS BEHIND ME BECAUSE I THE WHOLE VEHICLE STARTING JERKING AND EVENTUALLY JUST SHUT OFF. THE VEHICLE STILL READ THAT IT HAD GAS AT THAT POINT. IN FEBRUARY 2011 THE GAS GAUGE JUST QUIT WORKING ALL TOGETHER WOULD READ E EVEN WHEN YOU FILLED IT ALL THE WAY UP. HAD TO USE GALLONS USED TO TELL HOW MUCH FUEL WAS IN IT. MAY 2011 THE CHECK ENGINE LIGHT STARTED COMING ON AND OFF. JULY 11, 2011 I TOOK IT TO A GM SERVICE SHOP FOUND OUT THE ERROR FOR THE CHECK ENGINE LIGHT WAS THE FUEL SENSOR AND THE SAME REASON THE GAUGE WASN'T WORKING. $458 AND CHANGE TO HAVE IT FIXED. I HAD IT FIXED BECAUSE I COULDN'T AFFORD TO RUN OUT OF GAS ON THE FREEWAY AGAIN WITH THREE SMALL CHILDREN THAT ARE FREQUENTLY RIDING WITH ME. LOOKING FOR A RECALL BECAUSE THIS IS A VERY WIDESPREAD ISSUE AND A POTENTIALLY DANGEROUS ONE WHEN PEOPLE ARE RUNNING OUT OF GAS ON MAJOR FREEWAYS BECAUSE OF IT. *TR

Mileage: 79,000

THE FUEL SENSOR IN MY 2006 CHEVROLET TRAILBLAZER HAS BEEN SPURIOUSLY FAILING. IT DOES NOT ACCURATELY REPRESENT THE AMOUNT OF FUEL THAT IS IN MY TANK. SOMETIME IT WILL SAY THAT MY TANK IS FULL WHEN I KNOW THAT IT IS NOT, AND SOMETIMES IT WILL SAY THAT MY TANK IS EMPTY IMMEDIATELY AFTER FILLING IT. MY CAR HAS 65,000 MILES ON IT. *TT

Mileage: 65,000

THE FUEL GAUGE IN MY CHEVROLET TRAILBLAZER EXT FAILED RESULTING IN THE VEHICLE STALLING ON A BUSY ROAD. THIS IS THE SECOND TIME THAT THE GAUGE ON THIS CAR HAS MALFUNCTIONED (WAS REPAIRED BY THE DEALER AFTER A SIMILAR INCIDENT ABOUT 2 YEARS AGO). AT THIS TIME, THE GAUGE ONCE AGAIN DOES NOT WORK AT ALL. *TR

I HAVE A 2006 CHEVY TRAILBLAZER. I AM HAVING PROBLEMS WITH THE FUEL GAUGE. IT IS ALWAYS ON EMPTY, EVEN AFTER I FILL IT UP. I'VE CALLED CHEVY ABOUT THE PROBLEM. I'VE SEEN ON TOPIX.COM THAT ARE ABOUT 589 PEOPLE WITH THE SAME ISSUE. *TR

THE GAS TANK REGISTERS EMPTY EVEN WHEN FULL. GAS GAGE FLOATS RANDOMLY UP AND DOWN, NOT STAYING ACCURATE, GAS LIGHT COMING ON CONSTANTLY SAYING "LOW FUEL" EVEN AS PULLING AWAY FROM THE TANK AFTER A COMPLETE FILLUP. HAD BEEN DOING IT FOR A FEW WEEKS OFF/ON, NOW CONSTANT. GAUGE CONSTANTLY READING EMPTY, RARELY MOVING AT ALL. GAS LIGHT STAYS ON. NOW SEEMS TO BE CAUSING PROBLEMS WITH ENGINE/TRANSMISSION. CAR IS SUDDENLY MOVING SLOW WHEN ACCELERATING INITIALLY. *TR

WE RAN OUT OF GAS ON AN INTERSTATE HIGHWAY, DESPITE THE GAUGE INDICATING FUEL WAS LEFT IN THE TANK. WE DRIFTED TO A STOP ON THE SHOULDER AND I HAD TO OBTAIN FUEL FROM THE NEAREST SERVICE STATION 5 MILES AWAY AND THEN RETURN TO THE VEHICLE, LEAVING MY WIFE AND 3 YOUNG CHILDREN UNATTENDED. AFTERWARD, THE FUEL GAUGE ONLY PERIODICALLY FUNCTIONED FOR THE NEXT 2-3 FILL-UPS AND NOW DOES NOT WORK AT ALL - THE GAUGE CONSTANTLY READS "EMPTY" AND THE FUEL LIGHT IS ALWAYS ON. WE RAN OUT OF GAS ON ONE ADDITIONAL INSTANCE BECAUSE OF THIS MALFUNCTION ON A BUSY FREEWAY OFFRAMP AND NOW MUST CONSTANTLY CAREFULLY CHECK OUR MILEAGE EVERYTIME WE FILL THE TANK. *TR

2006 TRAILBLAZER EXT; FUEL LEVEL SENSOR, SENDING UNIT, ETC. AT 34,000 MILES AROUND SEPT, 2009 RIGHT AFTER FILLING UP, THE FUEL GAUGE WENT TO "EMPTY' AND THE LIGHT WENT ON WITH THE WARNING BELL SOUNDING 5 TIMES UPON STARTING THE VEHICLE. THE CHECK ENGINE LIGHT ALSO ILLUMINATED, BUT DID GO OFF BY ITSELF AFTER 1 DAY. THE GAUGE STAYED AT EMPTY FOR APPROXIMATELY 50 MILES AFTER WHICH IT BEGAN TO FUNCTION PROPERLY, AND THEN BELOW ABOUT A THIRD OF A TANK IT WENT TO ZERO AGAIN. OVER TIME THE PORTION OF TIME THE GAUGE FUNCTIONS PROPERLY HAS DECREASED. NOW IT REGISTERS ABOUT A QUARTER TANK FOR ONLY ABOUT 25 MILES WORTH OF DRIVING, TYPICALLY FROM 50 TO 75 MILES AFTER FILLING IT UP. I'VE BEEN AWARE OF THE PREPONDERANCE OF SIMILAR COMPLAINTS, AND HAVE PUT OFF GETTING IT FIXED...JUST USING THE ODOMETER...SO FAR THE ODOMETER STILL WORKS. A LOCAL CHEVY DEALER WOULD NOT COMMENT ON THIS AS A COMMON ISSUE, BUT WANTS A $49 MINIMUM TO LOOK AT IT, WHICH IS MORE LIKELY TO BE A FULL HOUR AT $99, JUST TO DIAGNOSE. I'M NOT INTERESTED IN HAVING A DEALER LOOK AT IT SINCE IT'S OUT OF WARRANTY, BUT WILL PUT UP WITH IT UNTIL I FIND A TRUSTWORTHY MECHANIC WHO WILL NOT FLEECE OUR FAMILY. THIS CONSTITUTES A SAFETY PROBLEM IN MY OPINION, BUT BEYOND MY OPINION THIS IS A KNOWN ISSUE THAT REMAINS UNRESOLVED BY GM TO MY KNOWLEDGE. THIS IS MY FIRST GM VEHICLE IN 20 YEARS, AND I CAN SAFELY SAY THAT UNLESS GM SHARES SOME RESPONSIBILITY IT WILL BE MY LAST. *TR

TODAY FOR THE 5TH TIME MY VEHICLE RAN OUT OF GAS, THIS TIME ON A BUSY HIGHWAY RIGHT AFTER I TURNED ONTO THE HIGHWAY. I HAD TO BE PUSHED OUT OF THE WAY OF TRAFFIC. A TRUCK CAME WITH FUEL AND I WAS ABLE TO GET TO A GAS STATION. ONE OF COURSE PAYS A MARK UP ON THE FUEL WHEN IT IS BROUGHT TO YOU. THE DEALERSHIP WHERE I PURCHASED IT DOES NOT SERVICE CHEVROLET'S ANY LONGER. ANOTHER DEALERSHIP IN TOWN SAYS THERE IS NOTHING TO BE DONE UNTIL THERE IS A RECALL. THIS IS VERY DANGEROUS. I WOULD LIKE TO SELL THE VEHICLE BUT WHO WOULD BUY A VEHICLE LIKE THIS? I MISSED A CLINIC APPOINTMENT, SOMEONE HAD TO COME PICK UP MY SON TO GET HIM TO SCHOOL AND I REARRANGED MY MORNING. THE PREVIOUS TIMES I HAVE BEEN ON MY WAY TO WORK OR IN TO TOWN. ONCE MY SON AND I HAD TO WALK INTO TOWN TO GET A GAS CAN AND WALK BACK WITH THE FUEL. ANOTHER TIME AAA CAME BUT I MISSED ALL MORNING OF WORK. ANOTHER TIME I WAS AT A STOPLIGHT AND IT RAN OUT OF FUEL AND MY OLDER SON AND SOME BASKETBALL PLAYERS, ALSO IN MY VEHICLE, PUSHED THE VEHICLE UP THE BLOCK INTO THE GAS STATION. THE OTHER TIME IT RAN OUT WHILE I WAS ON A MAIN STREET BUT I WAS ABLE TO COAST INTO A NEARBY GAS STATION. I WAS INFORMED THAT THE VEHICLE WAS OUT OF WARRANTY WHEN IT BEGAN AT ABOUT 75,000. I WAS TOLD IT WOULD BE 700$ AND MAYBE MORE TO FIX AND THAT TO EVALUATE IT MEANT PAYING MOST OF THE 700$. I WATCH MY FUEL MILEAGE VERY CAREFULLY SO I KNOW WHEN TO REFILL. TODAY IT STOPPED SOONER THAN IT SHOULD HAVE. SO NOW I CAN' T RELY EVEN ON THE MILEAGE. I WOULD NOT FEEL SAFE TAKING THIS VEHICLE ON ANY LONGER TRIP. FIVE TIMES IS TOO MANY IN 15 MONTHS ESPECIALLY WHEN IT STOPS SUDDENLY IN INTERSECTIONS AND ON HIGHWAYS. *TR

Mileage: 104,000

I HAVE A 2006 CHEVY TRAILBLAZER. SINCE MY VEHICLE HIT 69000 MILES MY FUEL GAUGE HAS BECOME INOPERABLE. I HAVE TRIED TO GET IT FIXED BUT IT IS $1300 AND NO GUARANTEE THAT IT WILL NOT HAPPEN AGAIN SINCE THE PART HAS NOT BEEN CHANGED. IT STALLS ON MANY OCCASIONS AS IF I HAVE NO GAS. I HAVE RUN OUT OF GAS SO I KNOW HOW MANY MILES I CAN GO. *TR

Mileage: 69,000

I HAVE A 2006 CHEVY TRAILBLAZER EXT WITH A FUEL SENDING GAUGE PROBLEM. WHEN I FILL THE TANK, THE GUAGE INDICATES A FULL TANK BUT THE "NEEDLE" STAYS LOCKED ON FULL UNTIL I'VE DRIVEN APPROXIMATELY 50 MILES - THEN THE NEEDLE SHOWS THE FUEL LEVEL AT ABOUT 3/4 OF A TANK. FURTHER DRIVING MAKES THE NEEDLE FLUCTUATE WILDLY UNTIL SOMETIME IN THE NEXT 50/100 MILES THE NEEDLE FALLS TO THE EMPTY MARK AND STAYS THERE. RECENTLY THERE HAS BEEN A NEW DEVELOPMENT: THE NEEDLE NEVER MOVES OFF THE EMPTY MARK WHEN I FILL UP AND TODAY, AFTER FILLING UP YESTERDAY, THE NEEDLE SITS ON THE EMPTY MARK WITH THE LOW FUEL LIGHT ON. I HAVE RESORTED TO BRINGING A GAS CAN WITH ME AND USING THE ODOMETER TO "GUESSTIMATE" THE AMOUNT OF FUEL I HAVE LEFT. NOT ALWAYS THE BEST SOLUTION. *TR

Mileage: 100,000

I STARTED HAVING PROBLEMS WITH THE FUEL GAUGE SWINGING BETWEEN FULL AND EMPTY THEN MY CHECK ENGINE LIGHT CAME ON. I'VE BEEN TOLD THAT I NEED AN WHOLE NEW FUEL PUMP ASSEMBLY AND THAT THE FUEL TANK WILL HAVE TO BE DROPPED TO REPLACE IT. I'VE BEEN JUST SETTING THE TRIP METER AND FILLING IT UP EVERY 250 MILES BECAUSE THE FUEL GAUGE NOW JUST STAYS LIT ON EMPTY ALL THE TIME. I DON'T HAVE ANY PROBLEMS WITH IT RUNNING, STARTING, ETC. SO I'M ASSUMING THAT IT'S JUST THE SENSOR THAT IS OUT. 2006 CHEVROLET TRAILBLAZER EXT. *TR

I FILLED MY VEHICLE WITH FUEL AND WENT TO START IT AND IT DIED. I RESTARTED IT AND IT LUGGED AND DIED. I STARTED IT AGAIN AND IT WAS RUNNING OK, BUT I NOTICED THE FUEL GAUGE WAS STUCK AT EMPTY AND MY LOW FUEL WARNING KEPT DINGING. ONCE MY TANK GOT TO ABOUT 3/4 FULL THE GAUGE WOULD WORK AGAIN. AFTER A FEW MONTHS, THE GAUGE NEVER WORKS AND I HAVE TO TRY TO KEEP A REALLY CLOSE EYE ON THE MILEAGE TO KNOW WHEN I NEED TO FILL UP. WE TOOK THE CAR TO AN AUTO PARTS STORE AND HAD THEM DO A READ ON THE COMPUTER BECAUSE OUR SERVICE ENGINE LIGHT IS ALSO ON HALF THE TIME. IT CAME BACK AS A "SENDING UNIT MALFUNCTION" IT COULD BE THE FLOAT OR THE SENDING UNIT. THE REPAIR WAS QUOTED AS $600.00 SO WE CANNOT AFFORD TO FIX IT YET. THE VEHICLE WAS ONLY AT 45,000 MILES WHEN THIS OCCURRED. *TR

Mileage: 45,000

THE GAS GAUGE FIRST STARTED BY READING THE WRONG AMOUNT OF FUEL, THEN ONLY AFTER RUNNING FOR ABOUT 10 MINUTES WOULD IT READ THE CORRECT AMOUNT OF FUEL. THE ABOUT 15 DAYS AFTER INITIAL ISSUE IT STARTED TO SHOW ONLY THE CORRECT AMOUNT OF FUEL WHEN IT WAS STARTED UP THEN IT WOULD GO TO EMPTY, EVEN IF THE TANK WAS FILLED UP. NOW IT CURRENTLY DOES NOT MOVE AND THE "LOW FUEL LEVEL" SHOWS UP EVERY TIME YOU START THE CAR. AFTER DOING MUCH RESEARCH ON THIS I REALIZED THERE WERE OTHER PEOPEL WHO WERE HAVING THE EXACT SAME PROBLEM.

I HAVE A 2006 TRAILBLAZER EXT AND THE TRACTION IS NO LONGER OPERATIONAL.. THIS IS UNACCEPTABLE AND NEEDS TO BE RECALLED AS I AM NOT THE ONLY ONE EXPERIENCING THIS ISSUE. DOES SOMEONE NEED TO BE KILLED BEFORE ACTION IS TAKEN? NOTHING HAS BEEN DONE TO CORRECT DUE TO THE HIGH COST FOR THE REPAIR. WHAT IS CHEVY GOING TO DO IN THAT IT IS A SERIOUS DEFECT WITH THEIR VEHICLE? SECONDLY, THE GAS GAUGE STOP WORKING AND I RAN OUT OF GAS. THIS IS ANOTHER SERIOUS DEFECT THAT WILL CAUSE OTHERS TO BE KILLED. ONCE AGAIN A RECALL NEEDS TO BE PUT IN PLACE BEFORE SOMEONE IS HARMED. WHERE IS CHEVY'S LIABILITY IN THESE ISSUES? *TR

LIKE THOUSANDS OF OTHER OWNERS (SINCE THIS HAPPENS TO THE GMC ENVOY TOO, SO IT'S NOT JUST A CHEVY ISSUE), ONE DAY THE GAS GAUGE WORKS FINE, THE NEXT IT READS EMPTY AFTER FILLING IT UP. HOWEVER, AS A BONUS, THE FRIENDLY CHECK ENGINE LIGHT NOW COMES ON RANDOMLY TO LET ME KNOW THE FUEL GAUGE ISN'T WORKING. I'VE HAD THE CODES READ BY TWO DIFFERENT PLACES AND THIS IS THE ONLY ERROR RECORDED. I NOW HAVE TO USE THE TRIP METER TO "GUESS" WHEN THE TRUCK NEEDS FILLING UP. SINCE IT'S GOING TO COST ME SEVERAL HUNDRED DOLLARS I DON'T HAVE TO FIX IT, I'LL JUST HAVE TO LIVE WITH THE INCONVENIENCE. IN MASSACHUSETTS, LIKE MANY OTHER STATES, THEY DO AN EMISSIONS TEST BY PLUGGING INTO THE VEHICLE'S COMPUTER. WELL, SINCE THE CHECK ENGINE LIGHT HAS COME ON AT SOME POINT, THE COMPUTER SAYS "NOT READY" AND THE VEHICLE FAILS THE TEST. YOU HAVE TO WAIT UNTIL THE LIGHT GOES OFF AND THEN DRIVE ABOUT A WEEK BEFORE THE COMPUTER RESETS ITSELF. HOWEVER, WITHOUT FAIL, THE LIGHT ALWAYS COMES BACK ON JUST BEFORE TAKING IT BACK TO GET RE-INSPECTED, THUS RESETTING THE WHOLE PROCESS. I'VE HAD THIS HAPPEN FOR THE LAST 3 WEEKS IN A ROW REGARDLESS OF NUMBER OF DAYS/MILES DRIVEN. ANOTHER WEEK AND ANOTHER TANK OF GAS WASTED. SO, IN ORDER TO GET THE CAR TO PASS INSPECTION, I EITHER HAVE TO GET REAL LUCKY WITH THE CHECK ENGINE LIGHT OR HAVE THE REPAIR MADE. SINCE THIS ISSUE PREVENTS THE VEHICLE FROM PASSING THE STATE INSPECTION, IT SHOULD BE CONSIDERED A SAFETY/EMISSIONS CONCERN AND ALL VEHICLES RECALLED TO REPAIR THE COMBINATION FUEL PUMP/SENDING UNIT. IF GM DOESN'T CONSIDER THIS A CONCERN AND RECALL THE VEHICLES FOR THIS REPAIR, THEN THEY NEED TO HAVE THE VEHICLES RECALLED TO HAVE THE CHECK ENGINE LIGHT STOP COMING ON SO THE VEHICLES CAN PASS STATE INSPECTIONS. *TR

THE ISSUES STARTED ABOUT A MONTH AGO WHEN I HAD TWO UNEXPECTED STALLS DUE TO EMPTY FUEL TANK. THE NEEDLE WAS INDICATING THAT FUEL WAS STILL AVAILABLE, THOUGH NEAR EMPTY. THEN FINALLY THE MYSTERY WAS SOLVED ON NOVEMBER 15 WHEN THE FUEL LEVEL SENDER FINALLY FAILED. I FILLED THE TANK NORMALLY BUT WHEN I STARTED THE VEHICLE, THE NEEDLE STAYED AT EMPTY, LOW FUEL LIGHT CAME ON AND LOW WAS DISPLAYED IN THE RANGE SPEEDO DISPLAY. AFTER A QUICK SEARCH, I REALIZED THE SOURCE OF ALL MY PROBLEMS. ANOTHER FAULTY TRAILBLAZER FUEL LEVEL SENDER. I PURCHASED THE PART FROM MY LOCAL DEALERSHIP AND REPLACED MY PART (NO NEED TO REPLACE THE ENTIRE PUMP ASSEMBLY). HOWEVER AT CLOSE INSPECTION, I SEE THAT GM HAS CHANGED THE DESIGN OF THE METAL "WIPERS" THE SLIDE ALONG THE RESISTOR SEGMENTS ON THE SENDER. CLEARLY THEY REALIZED AT SOME POINT THAT THE DESIGN NEEDED IMPROVEMENT. THE NEW SENDER'S WIPERS ARE FEWER IN NUMBER, BUT ARE WIDER AND APPEAR TO MADE FROM SLIGHTLY THICKER METAL. ALL CONSIDERED, THE NEW DESIGN IS MORE ROBUST AND I ANTICIPATE LONGER LIFE. UNFORTUNATELY, AS I READ ALL THE COMPLAINTS, WE ALL SHARE THE SAME ISSUE AND HAVE PAID VARIOUS AMOUNTS TO GET THE ISSUE RESOLVED. I AM FORTUNATE THAT IT ONLY COST ME THE PART AND ONE ENTIRE EVENING. OTHERS ARE NOT SO LUCKY, THEY PAY WHATEVER THE DEALERSHIP NEEDS TO FIX THE FAULTY PART. THIS IS CLEARLY WIDESPREAD, EARLY LIFE FAILURE AND SHOULD BE ADDRESSED BY GM WITH COMPENSATION FOR A FAULTY AND NOW IMPROVED DESIGN.

I BOUGHT A 2006 CHEVY TRAILBLAZER IN JANUARY 2009. ONCE I REACHED ABOUT 40,000 MILES, I STOPPED TO GET GAS AND AFTER I FILLED UP, MY LIGHT INDICATING I NEEDED GAS CAME ON (IT WAS NOT ON PRIOR TO GETTING GAS). I KNEW I HAD GAS SO I KEPT DRIVING; MY ENGINE LIGHT THEN CAME ON. BOTH OF THEM HAVE NOW BEEN ON FOR OVER A YEAR. IN ORDER TO REPLACE THE SENSOR, I NEED A $500 PART! I KEEP TRACK OF MY MILEAGE AND FILL UP EVERY 250 MILES. LAST WEEK, MY CAR JUST SHUT DOWN, WHILE TRAVELING DOWN A HILL WITH MY TWO CHILDREN, I WAS APPARENTLY OUT OF GAS. WE NEARLY CRASHED INTO MULTIPLE VEHICLES! I HAVE SEEN THAT THERE ARE HUNDREDS OF THE SAME PROBLEMS IN THIS VEHICLE AND I BELIEVE IT SHOULD DEFINITELY BE RECALLED. I LEARNED WHAT CAN HAPPEN WHEN SOMEONE THINKS THERE IS GAS IN THE TANK AND THERE IS NOT... I HAD TO TURN ON MY 4 WAYS AND HONK THE HORN BECAUSE I HAD NO BRAKES, NO STEERING, ETC... I HAD TO USE MY EMERGENCY BRAKE TO STOP AND HAD TO TELL MY 10 YEAR OLD TO HANG ON AND COVER HIS 2 YEAR OLD BROTHER!!! THE FACT THAT CHEVY HAS BEEN MADE AWARE OF THIS AND DONE NOTHING MAKES ME SICK! MY ENTIRE FAMILY WAS IN DANGER... THANK YOU! *TR

FUEL SENSOR AND/OR SENDING UNIT INSTALLED IN THE 2006 CHEVROLET TRAILBLAZER EXT IS DEFECTIVE. INITIALLY, THE NEEDLE BOBBLES BETWEEN THE ACTUAL FUEL LEVEL AND EMPTY BUT EVENTUALLY SITS AT THE EMPTY READING DESPITE THE ACTUAL FUEL LEVEL. THE DEFECT, WHICH SHOULD BE RECALLED, COULD RESULT IN THE VEHICLE RUNNING OUT OF FUEL, STALLING OUT AND POSSIBLE REAR ENDING BY ANOTHER VEHICLE. I HAVE BEEN TOLD BY SEVERAL DEALERSHIPS AND IT IS EVIDENT IN SEVERAL BLOGS THAT THE AVERAGE COST TO FIX THE PROBLEM IS $800.00.

AS WITH MANY OTHER POSTERS AND COMPLAINANTS, I TOO HAVE AN ISSUE WITH THE LOW FUEL LIGHT ON MY 2006 CHEVY TRAILBLAZER. IT WILL SHOW LOW FUEL EVEN AFTER FILLING UP AS WELL AS WAIVER FROM FULL TO EMPTY WHILE DRIVING. THIS NEARLY BECAME A PROBLEM AS MY FAMILY AND I WERE DRIVING ON A LONG STRETCH OF HIGHWAY IN WHICH NO GAS STATION WAS A ROUND FOR 100 MILES. THANKFULLY THE GAUGE WAS WRONG IN TELLING US IT WAS LOW AS IT COULD HAVE BEEN VERY BAD DUE TO THE TIME OF NIGHT WHEN WE WERE DRIVING. I HAVE NOT FIXED THE PROBLEM YET. FOR NOW I AM JUDGING MY GAS LEVEL BASED ON THE ODOMETER READING AND ESTIMATED GAS MILEAGE. PROBLEM BEGAN TO OCCUR AROUND 43,000 AND IS NOW AT 48,000 MILES. *TR

WHEN I FILL MY GAS TANK THE FUEL GAUGE GOES TO EMPTY AND STAYS THERE, AND SOMETIMES GOES ERRATIC UP AND DOWN SO YOU NEVER KNOW HOW MUCH FUEL IS IN THE TANK. I AM VERY AFRAID THAT BY NOT KNOWING HOW MUCH GAS IS IN THE TANK, IT MAY LEAD TO OVER FILLING AND CAUSING A FIRE HAZARD AT THE PUMP BY SPEWING GAS ALL OVER TO RUNNING OUT OF GAS IN A PASSING LANE OF A HIGHWAY POSSIBLY CAUSING SERIOUS INJURY TO MYSELF OR ANYONE ELSE IN MY 2006 TRAILBLAZER, TO INJURY OR DEATH TO ANYONE IN THEIR CAR THAT MAY HIT ME OR RUN INTO SOMEONE ELSE TO AVOID ME. THIS IS AN EXTREMELY DANGEROUS SITUATION THAT I SEE OCCURS TO MANY, MANY OTHERS WITH MY 2006 GM TRAILBLAZER SIMILAR MODELS OF DIFFERENT YEARS!!

CHEVROLET TRAILBLAZERS ARE HAVING PROBLEMS WITH FUEL GAUGE NOT WORKING PROPERLY. CHEVROLET KNOWS ABOUT THE PROBLEM AND THEY KNOW THAT LOTS AND LOTS OF THEIR TRAILBLAZERS ARE NOT WORKING PROPERLY WITH THE FUEL SENSORS AND ARE CHARGING PEOPLE $800-$1,000 TO FIX A PROBLEM THEY SHOULD RECALL. MY TRAILBLAZER HAS APPROXIMATELY 76,000 MILES AND THE FUEL GAUGE BROKE YESTERDAY. THIS IS A CONCERN BECAUSE YOU CAN NOT TELL WHEN YOU ARE LOW IN GAS. WHEN DRIVING DOWN THE INTERSTATE, YOU COULD CAUSE OR BE IN AN ACCIDENT IF YOUR CAR RUNS OUT OF GAS GOING DOWN A BUSY INTERSTATE AT 70 MPH NOT KNOWING IF YOU HAVE SUFFICIENT FUEL OR NOT. GM SHOULD RECALL THE TRAILBLAZERS SINCE SO MANY OF THE VEHICLES HAVE HAD A PROBLEM WITH THE GAS GAUGE. FUEL SYSTEM MALFUNCTIONS ARE DANGEROUS. *TR

THE AIR CONDITIONING ON MY 2006 CHEVY TRAILBLAZER EXT STOPPED WORKING. THE PROBLEM WAS THE BLOWER MOTOR RESISTOR MODULE AND RESISTOR MODULE CONNECTOR. THE PARTS HAD MELTED TOGETHER, CAUSING THE WIRES TO BECOME LOOSE AT THE CONNECTION. APPARENTLY THIS IS A COMMON PROBLEM WITH MY CHEVY MODEL. THERE ARE MANY ONLINE POSTINGS INDICATING THAT THE PROBLEM COULD CAUSE A FIRE. CHEVROLET COMPANY REFUSED TO EVEN LOOK AT MY VEHICLE UNTIL I PAID A $110.00 DIAGNOSTIC FEE. THE SERVICE TECHNICIAN IMMEDIATELY KNEW WHAT THE PROBLEM WAS AND EXPLAINED THAT IT WAS A COMMON PROBLEM WITH MY MODEL AND THE TAHOE. THE GAS GAUGE ALSO STOPPED WORKING RECENTLY WHICH I WAS TOLD BY THE TECHNICIAN THAT IT TOO WAS A COMMON PROBLEM. THERE ARE NUMEROUS COMPLAINTS ON THESE PARTS AS WELL AS THE BRAKE LIGHT CIRCUIT BOARDS, WHICH ALSO WENT OUT ON MY VEHICLE. THE TECHNICIAN ONCE AGAIN SAID THAT IT WAS A COMMON PROBLEM. THESE PARTS SEEM TO BE FAILING SHORTLY AFTER THE WARRANTY EXPIRES. THERE ARE MANY ISSUES WITH THE ELECTRICAL SYSTEM IN THIS VEHICLE. THE PROBLEMS ARE HAZARDOUS SAFETY ISSUES AND ARE KNOWN TO THE CHEVROLET CORPORATION. I WAS ABLE TO FIND THE PARTS AT NEARLY 80% CHEAPER THAN WHAT THE DEALER WANTED TO CHARGE ME, NOT INCLUDING THE LABOR AND DIAGNOSTIC FEE. SAFETY RECALLS ON THESE PARTS SHOULD BE ISSUED. *TR

3 WEEKS AGO, PER THE FUEL GUAGE HAD 1/4 TANK, NO 'LOW FUEL' LIGHT INDICATOR. HOWEVER, MY VEHICLE RAN OUT OF GAS, LEAVING ME TO COAST TO THE SIDE OF THE ROAD ON A CORNER. I WAS STRANDED. I HAVE NOT LET THE TANK GET THAT LOW SINCE, OUT OF FEAR THE GUAGE WAS NOT READING IT PROPERLY. LAST NIGHT, I FILLED THE VEHICLE. APPORXIMATELY A MILE FROM THE GAS STATION, MY CHECK ENGINE LIGHT CAME ON & THE GUAGE REGISTERED EMPTY WITH THE LIGHT INDICATOR. DURING MY 10 MINUTE DRIVE IT CONTINUED TO FLUCTUATE BETWEEN EMPTY & FULL. I AM AFFRAID OF THE VEHICLE CUTTING OUT AGAIN WHILE DRIVING IN TRAFFIC OR MANUEVERING THROUGH CORNERS.

2006 CHEVY TRAILBLAZER, FUEL GAUGE LIGHT AND FUEL INDICATOR ACTIVATES WHEN THERE IS STILL PLENTY OF GAS IN THE VEHICLE. ONCE THE GAS GETS DOWN TO 1/2 OR 1/4 TANK OF GAS IT WILL ACTIVATE THE EMPTY FUEL LIGHT. THIS IS A MAJOR CONCERN AND SAFETY PROBLEM AS IT IS MISLEADING. I DON'T KNOW HOW MUCH FUEL IS ACTUALLY IN THE TANK. IT COULD RUN DRY AND LEAVE A PERSON STRANDED. WE DO A LOT OF NIGHT DRIVING AND I CERTAINLY WOULDN'T WANT MY PREGNANT WIFE RUNNING OUT OF FUEL IN THE MIDDLE OF OUR "NOT SO SAFE" CITY WHICH BY THE WAY HAS ONE OF THE HIGHEST MURDER RATES IN THE STATES.

FUEL GAUGE ON MY 2006 CHEVROLET TRAILBLAZER HAS STARTED WORKING ERRATICALLY OR NOT AT ALL. EVERY TIME I FILL MY TANK, THE GAUGE STAYS AT EMPTY AT FIRST, THEN EVENTUALLY STARTS WORKING, BUT SOMETIMES ERRATICALLY. IT CAN GO UP OR DOWN FOR NO APPARENT REASON, SHOWING THE TANK AS BEING COMPLETELY EMPTY WHEN IT IS, IN FACT, FULL. I HAVE NOT REPLACED IT TO THIS POINT AS MY VEHICLE IS OUT OF WARRANTY, INSTEAD USING THE ODOMETER TO TRACK ACTUAL MILEAGE AND FILLING THE TANK ACCORDINGLY. BASED ON RESEARCH ON THE INTERNET, THIS APPEARS TO BE AN EXTREMELY COMMON PROBLEM WITH CHEVROLET TRAILBLAZERS BUILT SINCE 2004. THE AVERAGE COST TO REPAIR, AGAIN ACCORDING TO INTERNET RESEARCH IS $500-$700. THIS IS A SAFETY ISSUE BECAUSE IT COULD RESULT IN RUNNING OUT OF GAS IN AN INCONVENIENT OR DANGEROUS LOCATION, SUCH AS WHILE DRIVING AT HIGHWAY SPEEDS ON AN EXPRESSWAY, OR IN A SECLUDED OR INACCESSIBLE AREA.
