2007 Chevrolet Trailblazer Fuel System Problems

Fuel leak from line’s under truck

GAS GAUGE DOESN'T WORK. NEEDLE ON E AND LIGHT STAYS ON. PERSON I BOUGHT IT FROM REPORTS BROKEN WHEN SHE BOUGHT IT USED. I TRIP MILEAGE TO O WHEN I GET GAS. THEN BY # OF GALLONS I PUT IN I ESTIMATE HOW MANY MILES I THINK I CAN TRAVEL. IT'S NOT ALWAYS POSSIBLE TO KEEP TANK FILLED.

THE GAS GAUGE QUIT WORKING! I JUST PUT 50.00 DOLLARS IN MY GAS TANK AND DROVE 12 MILES TO GET MY THREE GRANDCHILDREN. WE WERE ON THE FREEWAY GOING 64 MILES PER HR IN THE FAST LANE. I HAD TO IMMEDIATELY GET OVER THREE LANES TO GET OFF THE FREEWAY BUT ONLY MADE IT TO THE SLOW LANE. I HAD TO CALL 911 BECAUSE IT WAS A VERY DANGEROUS SITUATION. I ALMOST GOT HIT EIGHT TIMES WAITING FOR THE STATE TROOPER TO GET TO ME SO HE COULD PUSH US OUT OF HARMS WAY WITH HIS PATROL CAR. I CAN'T BELIEVE THIS WASN'T A RECALL! THIS IS A BIG SAFETY ISSUE PLEASE DO SOMETHING ABOUT THIS.

ERRATIC FUEL GAUGE. FLUCTUATES CONSTANTLY BETWEEN FULL AND EMPTY. THIS OCCURS WHETHER THE VEHICLE IS IN MOTION OR AT A STOP. WHETHER THE TANK IS FULL OR PARTIAL DOES NOT MATTER. CANNOT RELY ON GAS GAUGE ANY LONGER. COULD CAUSE A STALL WHILE IN MOTION WHICH WOULD BE A SERIOUS SAFETY CONCERN. THERE ARE THOUSANDS OF COMPLAINTS REGARDING THIS MATTER ALL OVER THE INTERNET. A RECALL SHOULD BE PUT IN PLACE. BEFORE SOMEONE DIES.

FUEL GAUGE DOES NOT PROVIDE ACCURATE READING. CHECK ENGINE LIGHT INDICATES FUEL LEVEL SENSOR. I DO NOT KNOW IF THERE IS FUEL UNLESS I RESET THE TRIP ODOMETER AND MONITOR.

WHEN I FILL THE FUEL TANK, THE FUEL GAUGE SHOWS EMPTY AND THE LOW FUEL LIGHT COMES ON AND THE LOW FUEL ALARM WILL DING. SOMETIMES THE GAUGE WILL GO UP AND THEN BACK DOWN. SOMETIMES, THE GAUGE WILL SHOW CORRECTLY BUT YOU ARE NEVER SURE. THIS OCCURS WHEN MOVING OR SITTING ON A SLOPE OR ON FLAT GROUND.

SHORTLY AFTER CHRISTMAS 2015, WHILE DRIVING ON A CITY STREET THE RED LIGHT ON THE GAS GUAGE CAME ON AND THE GAUGE SHOWED EMPTY. HAVING JUST FILLED THE TANK EARLIER THAT DAY I THOUGHT THE GAS HAD BEEN STOLEN. I PULLED INTO A STATION TO REFILL BUT IT WAS STILL FULL. FOR THE NEXT FIVE WEEKS THE CHECK ENGINE LIGHT WAS ON AND THE GAUGE ONLY WORKED OCCASIONALLY. IT WASN'T A DANGEROUS SITUATION BUT AFTER A FEW WEEKS OF GUESSING HOW MUCH GAS WAS IN IT, I TOOK IT TO A REPAIRMAN WHO REPLACED THE FUEL PUMP MODULE ASSEMBLY FOR A MERE $767.04. THE ODOMETER IS ONLY AT 47,760.

I WAS DRIVING 10 MPH AND SUDDENLY THE NEDDLE OF THE GAS WENT ALL THE WAY DOWN LIKE I DIDN'T HAVE GAS, AND THE CAR TURN OFF ITSELF. SO I PUT THE GEAR IN PARK AND STARTED THE CAR AGAIN SO IT WORK AGAIN BUT THE NEEDLE TOOK 15 MINUTES TO GO UP ALL THE WAY TO FULL. AND I KNOW MY TANK WAS FULL BECAUSE I PUMP WAS THE NIGHT BEFORE. SO I KEEP DRIVING FOR 3 DAYS AND FILLED AGAIN MY TANK THE NIGHT BEFORE AND NEXT DAY I TURN ON THE CAR AGAIN THE NEDDLE WENT DOWN A QUARTER. THE MECANIC SAI WAS THE FUEL SENSOR PUMP GAS. AND I HEAR OTHER PEOPLE HAVE THE SAME PROBLEM. THE REPAIR COST ME 730 DOLLARS .

I RAN OUT OF GAS AND THE CAR LOCKED UP WHILE DRIVING BECAUSE MY FUEL GAUGE WENT OUT....UPDATED 08/25/15*BF

AFTER PICKING UP MY HUSBAND FROM WORK, WE STOPPED AT A STORE, WHERE I STAYED IN MY CHEVY TRAILBLAZER WHILE HUBBY WENT IN, I HAPPENED TO LOOKOVER AT GAUGES AND NOTICED THE FUEL GAUGE SLOWLY GOING DOWN. WHEN HUBBY CAME OUT OF STORE I HAD HIM CHECK TO SEE IF WE HAD A FUEL LEAK, AND NOTHING SEEMED TO BE LEAKING. WE LEFT STORE AND GAS GAUGE CONTINUED TO DECREASE UNTIL LIGHT CAME ON AND GAUGE READS EMPTY. THIS STARTED ABOUT A WEEK AGO AND CONTINUES TO BE AN ISSUE. *TR

GAS GAUGE NOT WORKING. FAULTY UNIT. *TR

THE FUEL LEVEL SENDING UNIT WAS LOOKED AT ABOUT 1 MONTH BEFORE JUNE OF 2007 AT 4500 MILES AND AGAIN AT JUNE 22ND AND THEN IT WAS REPLACED. THIS PROBLEM CONTINUED THROUGHT OUT THE LIFE OF THE VEHICLE I JUST MADE SURE IT HAD GAS IN IT. IT CAME ON AGAIN ABOUT SEPT 20TH OF 2014 AND STAYED ON FOR FIVE DAYS. ALL THIS TIME PASSED BECAUSE I DIDNT HAVE THE TIME TO MESS WITH IT. I DECIDED I HAD HAD ENOUGH AND TOOK IT TO GM IN OLATHE KANSAS WHERE THEY IN STALLED A NEW SENDING UNIT IT IS A NEW AND BETTER ONE THE CHARGED ME 108.88 AND I FEEL THEY SHOULD TAKE CARE OF THE WHOLE PRICE. *TR

VEHICLE DIC SHOWS "TIGHTEN FUEL CAP" MESSAGE. MESSAGE APPEARS EVEN IF FUEL CAP IS TIGHTENED. MESSAGE STILL ILLUMINATES AFTER REPLACING CAP. FUEL IN TANK CAN BE AT ANY LEVEL AND LIGHT STILL ILLUMINATES. *TR

SOME TIMES FUEL GAUGE READS EMPTY AND SOME TIMES READS FULL AND STILL IT MAY A THIRD EMPTY OR 16 GALLONS FULL. *TR

AFTER PURCHASING A TANK OF GAS AND DRIVING FROM THE SERVICE STATION, MY DISPLAY REGISTERED EMPTY AND THE CHECK ENGINE LIGHT DISPLAYED. I REVIEWED THE VEHICLE OWNER'S MANUAL AND DISCOVERED THERE WAS A SERIOUS PROBLEM. I RETAINED THE LETTER REGARDING THIS "POSSIBLE" SITUATION THAT I RECEIVED IN 2012 OR 2013 (NOT DATED), AND TOOK IT TO THE DEALERSHIP WHERE I NORMALLY HAVE MY CAR SERVICED. SINCE THE VEHICLE EXCEEDED THE ALLOWABLE MILEAGE (120,000), I WAS TOLD THEY WOULD NOT HONOR THE 50/50 PAYMENT AND THE COST ASSOCIATED WOULD BE 922.83 TO REPAIR. I TELEPHONED GENERAL MOTORS REGARDING THE CONDITION AND ADVISED THAT I FEEL THEY SHOULD BE 100% RESPONSIBLE FOR THE REPAIR, SINCE THE CONDITION WAS ANTICIPATED AND NOT DUE TO NORMAL USAGE. BASED ON THE DESCRIPTION OF THE PROBLEM AND CONTINUED SAFETY ISSUE, CHEVROLET SHOULD CORRECT THE PROBLEM AT NO COST TO THE OWNER. THIS REMAINS A SAFETY ISSUE THAT IS NOT ROUTINE OR ASSOCIATED WITH OTHER VEHICLES. THE COST IS EXCESSIVE AND I WAS INFORMED THAT GM WOULD NOT CORRECT THE PROBLEM OR PAY ANY PORTION OF THE ASSOCIATED COST; AT THE LEAST, ALL PARTS SHOULD BE COVERED TO CORRECT THIS ANTICIPATED PROBLEM. I WAS INFORMED THAT GM WOULD NOT PAY ANY COSTS ASSOCIATED WITH THE REPAIR. CONSUMERS ARE ASKED TO BUY AMERICAN PRODUCTS AND MANUFACTURERS DO NOT MAKE EVERY EFFORT TO ENCOURAGE CONTINUED PURCHASES. *JS

FUEL GAUGE ACTS RADICALLY GOING FROM EMPTY TO FULL. AT THIS TIME IS CAUSE THE VEHICLE TO STOP AND GO AS IF IT'S OUT OF GAS. THIS HAS HAPPEN AT 55 MILES AN HOUR TO LOW AS 35 MPH. THIS HAS HAPPEN WITH IN TRAFFIC ALMOST CAUSING THE PERSON FROM BEHIND TO HIT ME AT HIGH SPEEDS. THIS HAS HAPPEN IN A PART OF THE CITY WHERE A PERSON LIKE ME, A WHITE, FEMALE, AND ALONE AT THE TIME COULD HAVE LOST A LOT DUE TO THE HIGH CRIME RATE IN THE AREA. *TR

I FILLED THE TANK ON MAY 6, DROVE 4 MILES, GOT INTO THE CAR ON MAY 8, 2014 AND THE GAUGE SHOWED NO FUEL AND THE WARNING STATEMENT ON THE DASHBOARD SAID "LOW FUEL". I DROVE TO THE GAS STATION AND WAS TOLD THE TANK WAS FULL. TOOK THE CAR IN FOR SERVICE AND WAS TOLD THAT THE FUEL SENSOR HAD TO BE REPLACED. *TR
