2006 Chevrolet Trailblazer complaints

I HAVE A FAULTY FUEL LEVEL SENDER. IT STARTED AS READING EMPTY WHEN I FIRST FILL UP. AND THEN AFTER THE FUEL LEVEL WOULD GO DOWN SOME, IT WOULD FUNCTION NORMALLY. NOW IT SHOWS EMPTY ABOUT 90% OF THE TIME NO MATTER HOW MUCH FUEL IS IN THE TANK. NO CORRECTIVE MEASURES DONE AT THIS TIME. *TR

MY 2006 CHEVY TRAILBLAZER'S FUEL GAUGE GIVES FALSE FUEL LEVELS. WHEN I FILL IT UP THE NEEDLE MOVES UP A LITTLE AND GOES BACK TO EMPTY AND THE LOW FUEL LIGHT COMES ON. I BROUGHT THIS VEHICLE WHEN IT WAS BRAND NEW. I'VE HAD SO MANY PROBLEMS WITH THIS VEHICLE FROM THE DASH INDICATORS, RADIO, AND NOW THE FUEL GAUGE. THIS IS REALLY DANGEROUS BECAUSE I CAN RUN OUT OF GAS WHILE TRAVELING AND MAY HAVE AN ACCIDENT. I'VE SEEN ON THE INTERNET WHERE A OTHER TRAILBLAZER OWNERS ARE HAVING THE SAME PROBLEMS WITH THEIR FUEL SENSORS. FEEL THAT THIS PART MUST HAVE BEEN DEFECTIVE FROM THE FACTORY AND SHOULD BE REPLACED BY GM. *TR

WHILE DRIVING THE VEHICLE ON THE HIGHWAY MY TRAILBLAZER RAN OUT OF GAS. THE FUEL GAUGE STILL INDICATED BETWEEN 1/8TH TO 1/4 OF A TANK OF GAS LEFT. THIS LEFT MY FAMILY STRANDED ON THE SIDE OF THE ROAD FOR APPROXIMATELY 30 MINUTES. EVER SINCE THIS INCIDENT THE FUEL GAUGE READINGS ARE VERY SPORADIC AND INACCURATE.

WHILE TRAVELING DOWN A TOWN ROAD AT 40 MPH, MY TRAILBLAZER STALLED IN TRAFFIC. THE VEHICLE WOULD NOT START. THE GAS GAUGE WAS ON 1/4 OF A TANK. WE PUSHED THE TRAILBLAZER INTO A PARKING LOT. WE DISCOVERED THAT THERE WAS NO GAS IN THE TANK. AFTER PUTTING IN 3 GALLONS OF GAS IT STARTED. SINCE THEN EVERYTIME WE FILL UP THE TANK, IT READS EMPTY AND THE LIGHT ON THE DASH IS LIT WITH THE ENGINE SYMBLE. AFTER ABOUT 5 GALLONS ARE USED, IT WILL WORK WITH NO LIGHT ERATICALLY. WE NEVER KNOW HOW MUCH GAS IS IN THE TANK WITH THE GAUGE. WE HAVE RUN OUT OF GAS TWICE SINCE THEN WITH AUTOS HITTING THEIR BRAKES SUDDENLY(NOT VERY HAPPY).

GAS GAUGE BEGAN TO GIVE INACCURATE READINGS UNTIL IT FINALLY FAILED AND SHOWED ONLY EMPTY HAD TO REPLACE LEVEL SENSOR AND FUEL SEAL IN GAS TANK TTL COST 569.05. *TR

MY GAS GAUGE BEGAN FAILING SEVERAL MONTHS AGO. COULD NOT AFFORD TO GET FIXED. RAN OUT OF GAS 2X. USING TAX RETUR MONEY FOR REPAIR. COST IS $900!!!

GAS GAUGE STOPPED WORKING AND ENGINE LIGHTS STAYS ON. *TR

GAS GAUGE IN 2006 TRAILBLAZER IS ERRATIC AND INACCURATE. WHEN FILLED, THE GAUGE GOES TO EMPTY PROMPTING A CHIME FOR LOW FUEL. WE NEVER KNOW HOW MUCH FUEL IS LEFT. *TR

I OWN A 2006 CHEVY TRAILBLAZER WITH WHAT I BELIEVE TO BE A FAULTY GAS GAUGE. I WAS DRIVING HOME LAST NIGHT AND THE GAS LIGHT CAME ON (WHICH SIGNALS THAT FUEL IS NEEDED) AND WITHIN 5 MINUTES THE CAR HAD STALLED ON A MAJOR HIGHWAY (ROUTE 81). I "GOOGLED" TRAILBLAZER AND GAS GAUGE AND I SAW THE THAT THE NHTSA HAS OPENED A PROBE OF THIS ISSUE, AS IT MAY BE WIDESPREAD. THEREFORE, I AM SUBMITTING MY ISSUE SO THAT THE NUMBER CAN BE PROPERLY TRACKED IN THE EVENT A RECALL IS OPENED. *TR

MY VEHICLES GAS GAUGE SIMPLY CEASED WORKING WITH NO APPARENT REASON OR WARNING CAUSING ME TO RUN OUT OF GAS ON A VERY BUSY HIGHWAY. I TOOK MY VEHICLE TO A REPAIR SHOP WHO INFORMED ME THAT, MORE THAN LIKELY, ONE OF THE THREE SENSORS IN MY GAS TANK HAD CEASED WORKING AND THAT IT WOULD COST ME APPROXIMATELY $1200.00 TO REPAIR THE SAME, WHICH I CANNOT AFFORD AND WHICH HAS YET TO BE REPAIRED CAUSING ME NO END OF GRIEF AND AGGRAVATION.

TL*THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER. THE CONTACT NOTICED THAT THE FUEL GAUGE SENDER WAS READING INACCURATELY AND HE WAS UNABLE TO DETERMINE HOW MUCH GASOLINE WAS ACTUALLY IN THE VEHICLE. HE ALSO NOTICED THAT THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT DID NOT INFORM THE DEALER OR MANUFACTURER NOR WAS THE VEHICLE DIAGNOSED OR REPAIRED. THE CURRENT MILEAGES WERE 101,636 AND THE FAILURE MILEAGES WERE UNKNOWN.

IN MID-2010 THE FUEL GAUGE ON MY 2006 TRAILBLAZER BECAME ERRATIC AND SOON AFTER STOPPED WORKING. THE GAUGE IS ON EMPTY, THE FUEL LIGHT STAYS ON AND THE CHECK ENGINE LIGHT REMAINS ON CONTINUOUSLY. THE VEHICLE HAD ABOUT 40K MILES ON IT WHEN THE PROBLEM STARTED. *TR

MY GAS GAUGE HAS BEEN FLUCTUATING. SOMETIMES THE GAUGE WOULD SHOW EMPTY WHEN THERE WAS GAS. OTHER TIMES IT WOULD SHOW THERE WAS FUEL IN THE TANK AND THERE WASNT. I CALLED MY CHEVY DEALER AND TOLD THEM WHAT HAPPENED. THEY SAID THAT THEY HAD HEARD OF OTHER PEOPLE HAVING THIS PROBLEM, BUT THERE WAS NO RECALL. I WAS TOLD THAT THE REPAIR WOULD BE VERY EXPENSIVE BECAUSE THE FUEL TANK WOULD HAVE TO BE DROPPED. I WAS TOLD TO USE MY TRIP ODOMETER TO KEEP TRACK HOW MANY MILES WAS DRIVEN ON A TANK SO THAT I WOULDNT RUN OUT OF GAS. I WORK FOR GM AND I CONTACTED OUR LOCAL CUSTOMER SERVICE REP. I WAS TOLD TO HAVE THE REPAIR MADE, PAY FOR IT AND MAYBE SOMETHING COULD BE WORKED OUT. I AM FILING THIS COMPLAINT BECAUSE I HEARD THE USNHTSA WAS INVESTIGATING THIS SAME ISSUE. I WANTED SOMEONE TO KNOW THERE ARE MORE OF OUT HERE WITH THE SAME PROBLEM.

AFTER COMPLETELY FILLING UP MY GAS TANK I RESTARTED THE VEHICLE. THE GAS LIGHT CAME ON, LOW FUEL WARNING CHIMED AND THE GAS GAUGE READ EMPTY. I IMMEDIATELY RESTARTED AND GOT THE SAME INDICATIONS. WITHIN A MINUTE OR SO OF DRIVING THE LIGHT WENT OUT AND THE GAUGE BEGAN TO SLOWLY RISE. WHILE DRIVING THE GAUGE WOULD CONTINUE TO SLOWLY SWING UP AND DOWN, OCCASIONALLY SWINGING LOW ENOUGH TO TRIGGER THE LOW FUEL WARNING (EVERY 3-5MINUTES WHILE MOVING). AFTER ABOUT 1/4 TANK OF GAS HAD BEEN USED THE GAUGE SEEMED TO STABILIZE AND READ ACCURATELY. THE PERIOD OF ERRATIC BEHAVIOR RETURNED EVERY TIME THE TANK WAS FILLED AND APPEARED TO BE WORSENING (LASTING LONGER WITH EACH CYCLE). ON 12/09/2008 VEHICLE WAS SERVICED UNDER WARRANTY AT A DEALER AND THE FUEL LEVEL SENDING UNIT WAS REPLACED. THERE HAVE BEEN NO INCIDENTS SINCE. *TR

I HAVE A 2006 CHEVROLET TRAILBLAZER 4-WHEEL DRIVE SUV AND THE FUEL GAUGE STARTED READING HALF FULL OR EMPTY WHEN THE TANK WAS FULL. NOW, THE FUEL GAUGE SIMPLY DOESN'T WORK. I HAVE NOT YET PAID THE EXPENSIVE SUM TO REPLACE THE FUEL GAUGE SENDING UNIT AND AM NOW SIMPLY RELYING ON ODOMETER MILEAGE TO KNOW WHEN TO FUEL. *TR

2006 CHEVROLET TRAILBLAZER. THE GAS GAUGE HAS STOPPED WORKING COMPLETELY. THIS IS A SAFETY HAZARD BECAUSE IT IS IMPOSSIBLE TO KNOW HOW MUCH GAS IS LEFT IN THE GAS TANK. THIS IS A DANGER AS I COULD RUN OUT OF GAS WHILE DRIVING. ALTHOUGH I CAN USE THE ODOMETER TO "GUESS" ABOUT GAS, IT IS NOT A DEFINITE MEASURE OF THE AMOUNT OF GASOLINE I HAVE LEFT. I KNOW THAT THIS HAS BEEN AN ISSUE WITH OTHER CHEVROLET SUVS AND TRUCKS. I CHECKED ON FIXING THE PROBLEM BUT BECAUSE THE ENTIRE GAS TANK HAS TO BE PULLED FROM THE VEHICLE, IT WILL COST APPROXIMATELY $800 TO FIX THE PROBLEM. BECAUSE THIS APPEARS TO BE A RECURRING PROBLEM WITH CHEVROLET AND GMC SUVS AND TRUCKS, I BELIEVE THAT THIS IS AN ISSUE THAT SHOULD BE ADDRESSED BY CHEVROLET AND GMC. *TR

INACCURATE GAS GAUGE. UNEXPLAINED STALLS. THE GAS GAUGE INITIALLY WOULD SHOW MORE GAS THAN WAS AVAILABLE AND LATER DIGRESSED TO ALWAYS SHOWING EMPTY. CONTINUOUS PROBLEM. 6 STALLS IN WHICH THE VEHICLE WOULD NOT START AFTER STALING. ALL STALLS OCCURRED IN PARKING LOST WITH NO ACCIDENTS. WAITING 30 MINUTES TO RESTART THE VEHICLE. FROM NOVEMBER 2010 TO PRESENT. *TR

SPRING OF 2010, I ENCOUNTERED AN ERRATIC MALFUNCTING FUEL GAS. I ACTUALLY RAN OUT OF GAS JUST ONCE! GAUGE WOULD SHOW FULL, EMPTY, FUEL LIGHT ON, GAUGE MOVING UP AND DOWN. SOME DAYS IT WORKED FINE. I FINALLY HAD THE "FUEL PUMP ASSY / SENDER UNIT" REPLACED AT A COST OF $762. THAT FIXED THE PROBLEM. NOT HAPPY!

WHILE DRIVING ON THE HIGHWAY THE 2006 CHEVROLET TRAILBLAZER STALLED. I PULLED OVER TO THE SIDE OF THE ROAD SAFELY AND WAS UNABLE TO START THE VEHICLE. WE HAD IT TOWED TO A GARAGE AND HAD TO PAY OVER $500 IN PARTS AND LABOR TO GET IT FIXED. IN THE END THE MECHANIC STATED THAT THEY COULD NOT FIND THE FAULT, IT JUST FINALLY STARTED. THE FUEL GAUGE HAS SINCE FAILED AND READS EMPTY ALL THE TIME. BEFORE THE FUEL GAUGE FAILED IT WOULD GIVE INACCURATE FUEL READINGS. WE HAVE ALSO HAD NUMEROUS STALLS SINCE THAT ARE RESOLVED BY WAITING FOR 30 MINUTES AND TRYING AGAIN. *TR

WAS READING A NEWS ARTICLE TODAY THAT NHTSA IS INVESTIGATING FUEL GAUGE ISSUE ON GM SUV'S. CONSIDERING MY EXPERIENCE, I THOUGHT NHTSA WOULD WANT TO KNOW OF THIS ISSUE AND THE RESOLUTION. BACK IN FEBRUARY 2010 THE FUEL GAUGE ON MY GOVERNMENT ISSUED 2006 CHEVY TRAILBLAZER STARTED TO ACT IN A STRANGE WAY. UPON FUELING UP IT WOULD READ FULL, THEN GO TO EMPTY IN A MINUTE, THEN GO BACK TO 1/2 FULL, THEN BACK TO EMPTY AND THEN AFTER 20 MINUTES IT WOULD STAY ON EMPTY FOR A DAY OR SO, THEN GO BACK TO A "NORMAL" READING. DURING THE TIME THIS HAPPENED, AND UNTIL IT WAS REPAIRED AT A GOV AUTHORIZED REPAIR GARAGE, I HAD TO USE APPROXIMATE MILAGE TO CONFIRM HOW MUCH FUEL REMAINED. IT TURNED OUT, ACCORDING TO THE REPAIR FACILITY, THAT A PUMP IN OR AT THE FUEL TANK HAD TO BE REPLACED. HAVE NOT HAD THAT ISSUE SINCE THE REPAIR. REPAIR WAS DONE OUTSIDE OF WARRANTY AND COST $457 ($300 IN LABOR, $157 FOR THE GAUGE UNIT) TO HAVE IT FIXED.

FUEL LEVEL SENSOR QUIT WORKING SO THAT GAS TANK ALWAYS SHOWED EMPTY. AN EXHAUSTIVE INTERNET SEARCH TURNED UP A LOT OF OTHER PEOPLE WITH THE SAME PROBLEM. TRIED TO GET CHEVY TO REPLACE UNDER WARRANTY AS A KNOWN FAILURE BUT THEY WOULD NOT. FINALLY PAID A DEALER TO FIX IT. THIS IS A WELL KNOWN PROBLEM TO CHEVY THAT THEY FAILED TO RECALL OR FIX.

I HAVE A 2006 CHEVY TRAILBLAZER. THE FUEL GAUGE GIVES EMPTY READING MOST OF THE TIME AND WILL THEN SHOW A HIGH FUEL LEVEL READING. I HAVE 105000 MILES ON IT. THE FUEL LEVEL READING CAN NOT BE TRUSTED. THIS STARTED AFTER FILLING THE FUEL TANK ON TIME. IT WAS NOT OVERFILLED. *TR

GAS GAUGE FAILURE. ALWAYS SHOWS VEHICLE ON EMPTY AND CAUSES THE "CHECK ENGINE" LIGHT TO ILLUMINATE. ALSO CAUSES CONTINUOUS ALARM DINGS AS TO "LOW FUEL". *TR

WE OWN A 2006 CHEVROLET TRAILBLAZER. THE DRIVER ADDED FUEL TO THE TANK; HOWEVER, THE GAS GAUGE INDICATED THAT IT WAS EMPTY. THE DRIVER TURNED THE VEHICLE OFF AND BACK ON TO SEE IF THE GAUGE WOULD RESET; TO NO AVAIL. THE FOLLOWING DAY THE GAS GAUGE DID INDICATE THAT THE FUEL TANK WAS FULL; YET, WHILE DRIVING APPROXIMATELY 25 MPH, THE GAUGE SLOWLY BEGAN TO MOVE UP AND DOWN BUT NEVER INDICATING THAT THE TANK WAS FULL. SINCE THE FUEL GAGE HAS MALFUNCTIONED, THE CONTACT IS UNSURE OF HOW MUCH FUEL WAS IN THE TANK. THE ENGINE SHUT OFF A MONTH AGO BECAUSE THE FUEL TANK WAS EMPTY AND THE FUEL GAUGE DID NOT INDICATE THAT. THE DRIVER DID CONTACT A MECHANIC WHO STATED THAT THEY NEEDED TO REPLACE THE FUEL PUMP. A MECHANIC STATED THAT THE FAILURE WAS COMMON FOR TRAILBLAZERS AND THE IT WOULD COST BETWEEN $600-$1200. TO REPAIR THE VEHICLE. THE FAILURE MILEAGE WAS 70,000 AND THE CURRENT MILEAGE IS APPROX. 76,000. *TR

GAS GAUGE ON 2006 CHEVY TRAILBLAZER FAULTY. DOES NOT SHOW CORRECT AMOUNT OF GAS IN TANK. I NOTIFIED GM SAYING I DID NOT THINK IT WAS RIGHT FOR THE GAUGE TO BE BAD ALREADY BECAUSE IT WAS ONLY A 2006 VEHICLE. I WAS GIVEN THE RUN AROUND AND THEY BASICALLY SAID THEY WOULD NOT FIX IT. *TR

I WAS TRAVELING ON FOUR-LANE DIVIDED HIGHWAY WHICH IS ONE OF THE MAJOR THOROUGHFARES FOR OUR CITY WHEN THE VEHICLE SUDDENLY SHUT OFF. THE GAS GAUGE READ ABOVE EMPTY, HOWEVER THE VEHICLE RAN OUT OF GAS. TRAFFIC WAS FAIRLY HEAVY AT THE TIME AND HAD I NOT BEEN TRAVELING IN THE RIGHT LANE AND ABLE TO READILY REACH THE EMERGENCY LANE THE SAFETY OF MY PASSENGER AND MYSELF COULD HAVE BEEN IN JEOPARDY,

FUEL GAUGE DOES NOT WORK PROPERLY AND FLUCTUATES BETWEEN BEING EMPTY OR BEING FULL. MUST USE TRIP ODOMETER TO MONITOR MILES IN ORDER NOT TO RUN OUT OF GAS. ORIGINALLY WHEN PROBLEM STARTED, FUEL GAUGE WOULD READ EMPTY AFTER FILLING UP TANK AND THEN AFTER APPROXIMATELY 25-30 MILES OF DRIVING GAUGE WOULD READ AS BEING FULL. NOW GAUGE JUST CONSTANTLY FLUCTUATES BETWEEN EMPTY OR FULL.

I OWN A 2006 CHEVROLET TRAILBLAZER WITH ABOUT 87000 MILES ON IT. RECENTLY THE FUEL GAUGE HAS BEEN SHOWING EMPTY UPON STARTING WITH THE LOW FUEL LIGHT BEING ON. AS YOU DRIVE SOMETIMES THE GAUGE WILL SHOW THE AMOUNT OF FUEL IN THE TANK AND SOMETIMES IT VARIES AND IS ALL OVER THE PLACE MAKING IT IMPOSSIBLE TO DETERMINE HOW MUCH FUEL YOU HAVE LEFT. I AM MAKING IT A HABIT TO MONITOR MY MILES SO AS TO NOT RUN OUT OF FUEL. NO ACCIDENTS OR INJURIES HAVE OCCURRED RELATED TO THIS ISSUE, IT IS JUST A NUISANCE AT THIS TIME. I HAVEN'T HAD IT REPAIRED AS IT INVOLVES REPLACING THE FUEL PUMP/SENDING UNIT AT AN ESTIMATED COST OF $800. THIS IS JUST AN FYI TYPE THING TO SHOW YOU THAT MANY OF THESE TYPE VEHICLES HAVE THIS ISSUE. THANK YOU FOR YOUR TIME. *TR

MY 2006 BRAND NEW CHEVY TRAILBLAZER ODOMETER COMPLETELY FAILED IN 2009. I DID NOT THINK MUCH ABOUT IT UNTIL MY BROTHER, AND SISTER BOTH COMPLAINED ABOUT THE SAME ISSUE ON THEIR NEW VEHICLES WHAT MAKES IT SO BAD IS THAT THE GAUGE IS IN THE TANK, AND THE COST TO FIX THE PROBLEM AT THE DEALERSHIP WAS $700. WHEN I SAW THAT AN INVESTIGATION WAS ONGOING, I WANTED TO LOG MY COMPLAINT. THIS CANNOT BE A COINCIDENCE. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL GAUGE WOULD PROVIDE INACCURATE FUEL LEVEL READINGS SPORADICALLY. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT REPAIRED. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 50,000 AND THE CURRENT MILEAGE WAS 73,000.

FUEL GAUGE STARTED TO FLUCTUATE ABOUT A MONTH AGO. THE VEHICLE HAS APPROX 135K MILES ON IT. HAD ONSTAR RUN DIAGNOSTIC AND SHOWED "HIGH FUEL SENSOR" ERROR TO TAKE THE CAR IN FOR SERVICE...SERVICE ENGINE LIGHT CAME ON AS WELL. WHEN THE TANK IS FULL, SAME ISSUE AS OTHERS HAVE HAD, THE GAUGE REGISTERS EMPTY THEN STARTS TO GO UP AFTER SEVERAL HOURS. TO THIS DATE, THE ENGINE LIGHT GOES ON AND OFF; EVERY TIME PUT GAS IN REGISTERS EMPTY TO HALF WHEN FULL. I HAVE RAN OUT OF GAS ONCE LAST WEEK ON WAY TO WORK, LUCKILY I WAS NOT ON INTERSTATE YET WHEN GAUGE READ I HAD ALMOST HALF TANK. WHEN I TOOK TO DEALER FOR REGULAR OIL CHANGE ASKED THEM TO CHECK IT. THEY CONFIRMED BAD SENSOR AND $600 REPAIR COST TO DROP TANK AND FIX ISSUE. THE PART COSTS $45 AT LOCAL AUTO PARTS STORE - CRAZY! SINCE THIS IS AN ISSUE THAT ALL DRIVERS ARE HAVING GM SHOULD ISSUE THE RECALL AND FIX THE ISSUE! *TR

I HAVE REPLACED THE FUEL GAUGE,FUEL PUMP ON MY 2005 TRAILBLAZER AFTER IT QUIT WORKING. I ALSO HAVE A 2006 TRAILBLAZER AND MY WIFE RAN OUT OF GAS, WHEN WE FILLED IT UP, THE GAS GAUGE DID THE SAME THING AS THE 2005, SO WE HAVE TO USE THE ODOMETER TO KNOW WHEN TO FILL UP. WHEN I CALLED MY MECHANIC, HE EXPLAINED THE SITUATION WAS THE SAME AS MY 2005. THIS IS A VERY EXPENSIVE REPAIR. *TR

OVER THE PAST FEW MONTHS, THE FUEL GAUGE ON MAKES FALSE READINGS ON A 2006 CHEVY TRAILBLAZER SS 6.0L. UPON FILLING UP TO A FULL TANK THE GAGE WILL SAY 'FULL' HOWEVER WHILE RIDING OVER BUMPS OR ACCELERATING/DECELERATING THE GAUGE WILL BOUNCE TO EMPTY AND FULL REGARDLESS OF THE ACTUAL FUEL LEVEL. THIS HAS OCCURRED FOR THE PAST 20,000 MILES CONTINUOUSLY AFTER FILL UP UNTIL APPROXIMATELY HALF THE TANK IS EMPTIED. ONCE THE GAUGE STOPS BOUNCING BETWEEN FULL AND EMPTY THE READING IS NO LONGER ACCURATE. IN ONCE CASE I RAN OUT OF FUEL WHILE ON A HIGHWAY WHILE THE GAUGE READ 1/4 TANK MOMENTS PRIOR TO RUNNING OUT OF GAS AND STALLING OUT. I WAS TOLD THERE IS AN ELECTRICAL SHORT OCCURRING IN THE FUEL SENDING UNIT AND IS A KNOWN PROBLEM AND WOULD REQUIRE REPLACING THE ENTIRE SENDING UNIT TO FIX THE ISSUE. *TR

FUEL GAUGE READS EMPTY WHEN IT IS FULL. *TR

2006 CHEVY TRAILBLAZER FUEL GAUGE STOPS WORKING. *TR

GAS GAUGE BEGAN FLUCTUATING THEN FAILED. NEEDLE GOES BETWEEN FULL AND EMPTY AT ANY GIVEN TIME. (CAUSED BY FAULTY FUEL LEVEL SENSOR/SENDER) I HAVE HAD TWO OTHER GM VEHICLES IN THE PAST TEN YEARS THAT HAVE HAD THEIR GAS GAUGES FAIL. OBVIOUSLY A COMMON PROBLEM WITH GM VEHICLES THAT THEY HAVE FAILED TO CORRECT.

IMMEDIATELY AFTER REFUELING TO FILL TANK AND STARTING VEHICLE, THE FUEL GAUGE WENT TO FULL, BACK DOWN TO EMPTY, THEN TO HALF FULL. THE GAUGE CONTINUED TO FLIP BACK AND FORTH. AT EACH FALSE "EMPTY" THE CHIME RANG AND YELLOW LIGHT APPEARED .THE GAUGE CONTINUED TO DO THIS IF FULL OR CLOSE TO EMPTY. EVERY TIME TANK WAS FILLED THE TRIP ODOMETER HAD TO BE RESET TO ZERO AND DATE AND NUMBER OF GALLONS NOTED. THIS IS THE ONLY WAY WE CAN TRACK FUEL CONSUMPTION. WE CANNOT TRUST THE GAUGE READINGS AT ALL. WE HAVE TO DO EXPRESSWAY DRIVING TO COMMUTE AND HAVE TO REFUEL MORE OFTEN TO KEEP TRACK. WE WORRY ABOUT SAFETY OF US AND OTHERS!

FAULTY FUEL GAUGE. STARTED TO GO BAD AT LESS THAN 67000 MILES. GOES TO EMPTY WHEN FILLED THEN FLUCTUATES. NEVER KNOW HOW MUCH GAS YOU HAVE. YOU ARE CONSTANTLY LOOKING AT THE TRIPOMETER TO TRY AND FIGURE OUT HOW MUCH GAS YOU HAVE. THIS IS A TRAFFIC HAZARD. GM SHOULD DO A RECALL. THOUSANDS OF COMPLAINTS ON INTERNET. NOTIFIED GM THEY WOULD NOT DO ANYTHING. *TR

GAS GAUGE FAILS AFTER FILLING TANK. WILL START READING CORRECTLY AFTER A COUPLE OF TRIPS WITH VEHICLE AND WHEN GAS USAGE GETS TO ABOUT 8 GALLONS USED, GAGE WILL READ EMPTY AGAIN AND CHECK ENGINE LIGHT COMES ON BECAUSE IT THINKS IT IS OUT OF GAS. *TR

GAS GAUGE DOES NOT WORK. ENGINE LIGHT AND FUEL LIGHTS STAY ON CONSTANTLY. WIFE HAS RUN OUT OF GAS SEVERAL TIMES REQUIRING ROADSIDE ASSISTANCE AND PLACING HER IN DANGER OF ACCIDENT. *TR

MY GAS GAUGE WAS MOVING FROM FULL TO 3/4 FULL BACK TO FULL AND ALL OVER THE GAUGE. EVENTUALLY IT HAS STAYED AT EMPTY WITH THE LIGHT ON. I HAVE TO GAGE MY GAS FILLING WITH THE ODOMETER. *TR

INACCURATE FUEL LEVEL 2006 TRAILBLAZER. SOMETIMES WHEN I FILL THE TANK THE LOW FUEL LIGHT GOES ON AND THE GAUGE GOES TO EMPTY. OTHER TIMES IT LOOKS LIKE IT HAS ABOUT A TANK AND A HALF ON THE NEEDLE. SOME DAYS THE GAUGE WONT WORK AT ALL. I HAVE RESORTED TO USING THE TRIP ODOMETER BECAUSE THE GAUGE IS TOTALLY INACCURATE. *TR

THE FUEL GAUGE IS INACCURATE. EVERYTIME I FILL UP MY GAS TAKE IT STAYS ON E WITH THE FUEL LIGHT ON. AFTER DRIVING MAYBE 60 MILES OR MORE IT WILL RE-READ HOW MUCH FUEL IS IN MY TANK. WITH 3/4 TANK IT ALMOST IMMEDIATELY JUST DECREASES DOWN TO E AGAIN AND WILL STAY THERE. TOOK IT TO THE DEALERSHIP BUT WAY TO EXPENSIVE TO REPAIR. I HAVE TO TRACK MY MILES AND HAVE NOTICED IN ONLINE FORUMS THAT I'M NOT THE ONLY COMPLAINT ABOUT THIS ISSUE WITH THE TRAILBLAZERS AND ENVOYS. *TR

TWO DAYS BEFORE WE WERE TO LEAVE ON VACATION IN OUR 2006 TRAILBLAZER, MY WIFE FILLED UP THE GAS TANK AND WHEN SHE GOT IN THE CAR IT READ BELOW EMPTY AND THE CHECK ENGINE LIGHT WAS ON. SHE IMMEDIATELY WENT TO A SHOP WHERE SHE WAS TOLD "IT;S PROBABLY THE SENDING UNIT, THEY GO BAD ON TRAILBLAZERS ALL THE TIME". THIS WAS BEFORE A DIAGNOSTIC TEST, AND THE TEST CONFIRMED IT. BEING THAT IT IS A CERTIFIED USED VEHICLE, 5 YEARS OLD WITH 50,000 MILES, WE TOOK IT TO THE DEALER. THEY SAID THEY COULD DO IT FOR $470.00 AND IT WAS NOT UNCOMMON. I AM 50 YEARS OLD AND HAVE OWNED A DOZEN VEHICLES OVER THE YEARS, MOST OLDER THEN THIS, AND HAVE NEVER HAD THIS PROBLEM, EVER, ON ANY VEHICLE. SINCE WE WERE LEAVING ON A VACATION IN TWO DAYS, WE FELT WE HAD BETTER HAVE IT FIXED, EVEN THOUGH WE COULD NOT AFFORD IT. I HAVE SINCE TALKED TO OTHER MECHANICS, AND ASKED IF THERE ARE ANY PROBLEMS WITH TRAILBLAZERS FROM 2006. EVERY TIME I HAVE BEEN TOLD "NOT REALLY, OTHER THEN THE FUEL SENDING UNITS, WHICH IS AN EXPENSIVE FIX". UNFORTUNATELY I HAVE EXPERIENCED THAT FIRSTHAND. WHILE I CAN'T REPLACE THE THINGS WE COULDN'T DO ON OUR VACATION DUE TO THE COST OF THE REPAIR, I WOULD SURE LIKE TO KNOW HOW TO GET MY MONEY BACK. AND SINCE THE NEW ONE CAME FROM THE DEALER AND IS OEM EQUIPMENT, HOW LONG WILL THIS ONE LAST? ANY HELP YOU CAN PROVIDE WILL BE GREATLY APPRECIATED. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FRONT DRIVER SIDE AUTOMATIC DOOR LOCK AND WINDOW REGULATOR FAILED TO OPERATE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 92,000. THE VIN WAS UNAVAILABLE.

2006 CHEVROLET TRAILBLAZER LT. WHILE DRIVING AT NIGHT, LOWBEAM HEADLIGHTS GO OUT. HAPPENS AT VARIOUS SPEEDS, HAPPENS SPORADICALLY. THIS HAS OCCURRED 2 TIMES BEFORE. THE TIMES BEFORE WAS IN SEPTEMBER 2010 MILEAGE UNKNOWN AT THE TIME WHILE DRIVING IN MY NEIGHBORHOOD. THEN ON OCTOBER 08, 2010, AT 91,164 MILES WHILE DRIVING HOME ON THE INTERSTATE AT 70MPH IN THE OCCURRENCES IN 2010 LOWBEAM HEADLIGHTS WENT OUT WHILE DRIVING, THEN INDEPENDENTLY RE-ILLUMINATED WITHIN SECONDS. THE LATEST OCCURRENCE HAPPENED ON APRIL 16, 2011 AT 10:50PM. I HAD JUST DRIVEN VEHICLE 20 MINUTES EARLIER AND HAD NO PROBLEMS. MY WIFE USED THE VEHICLE AT 10:45PM AND LOWBEAM HEADLIGHTS WENT OUT WHILE DRIVING AT 40-45MPH. SHE STATED IT TOOK REPEATED TRIES WITH HEADLIGHT SWITCH TO GET THE LIGHTS TO RE-ILLUMINATE. WIFE PULLED TURNSIGNAL ARM BACK AND HIGHBEAM LIGHTS WOULD ILLUMINATE THE FLASH TO PASS FEATURE. NO OTHER ELECTRICAL PROBLEMS PRESENT. THIS HAPPENED WHILE DRIVING IN NEIGHBORHOOD AT LOW SPEED. THIS IS A CONDITION THAT COULD BE VERY DANGEROUS AT HIGHWAY SPEEDS. THIS VEHICLE HAS AUTOMATIC HEADLIGHTS, THEY COME ON AUTOMATICALLY AT DUSK, AND THE HEADLIGHT SWITCH IS LEFT IN THE AUTOMATIC MODE AND NEVER TOUCHED. I HAVE OWNED THIS VEHICLE SINCE 19,000-20,000 MILES, WAS A GM EXECUTIVE/DEMO VEHICLE. *TR

2006 CHEVY TRAILBLAZER, FUEL GAUGE ACTS ERRATIC AND CHECK ENGINE LIGHT COMES ON. IT HAPPENS EVERY TIME I FUEL UP. *TR

FAULTY GAS GAUGE SENSOR ON 2006 TRAILBLAZER. *TR

FUEL GAUGE FLUCTUATION, CAUSING THE LOW FUEL LIGHT TO ILLUMINATE. EVENTUALLY GAUGE DROP TO EMPTY PERMANENTLY. *TR

ABOUT 3 MONTHS AGO AFTER FILLING THE GAS TANK ON MY 2006 CHEVROLET TRAILBLAZER THE GAUGE BEGAN TO DROP TO EMPTY AND "DANCE" AT A NEARLY EMPTY LEVEL FOR A FEW MINUTES. THE PROBLEM APPEARED TO CORRECT ITSELF, THEN A FEW WEEKS AND A COUPLE OF "DANCES" LATER THE GAUGE READ EMPTY AND THE FUEL LIGHT WAS PERMANENTLY ON. THE PROBLEM STILL PERSISTS TODAY. *TR
