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.

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

Jan 1, 2015

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

INACCURATE FUEL LEVEL READING. IN NOVEMBER, MY FUEL GAUGE AND DRIVER INFORMATION CENTER BEGAN TO SPONTANEOUSLY READ ERRATICALLY AND WOULD NOT ACCURATELY SHOW ME HOW MUCH GAS I HAD. CONDITION HAS RAPIDLY PROGRESSED TO WHERE THE FUEL GAUGE ALMOST CONSTANTLY READS EMPTY, LOW FUEL LIGHT IS ILLUMINATED AND FUEL LEVEL LOW IS DISPLAYED IN THE DIC. IN RESEARCHING THIS ISSUE, I FOUND SERVICE BULLETIN NO. 10054B WHICH STATES IT IS A PREMATURE WEARING OF THE FUEL SENSOR AND I SHOULD HAVE RECEIVED A MAILED NOTICE FROM GM REGARDING THIS KNOWN ISSUE. I HAVE NOT RECEIVED ANY SUCH NOTICE. THERE ARE NO RECALLS ASSOCIATED WITH MY VIN AND MY WARRANTY HAS NOW EXPIRED SO THERE WILL NOT BE "VEHICLE ELIGIBILITY" FOR THE DEALER TO CONFIRM THROUGH THE "APPLICABLE WARRANTIES SECTION IN THE GLOBAL WARRANTY MANAGEMENT SYSTEM." THIS ISSUE IS BIGGER THAN PUBLICLY ACKNOWLEDGED BY GM AND NEEDS TO BE A FULL RECALL, NOT A 50/50 SHARED RESPONSIBILITY WITH THE CUSTOMER WHEN GM ACKNOWLEDGES THE ISSUE IS DUE TO A FAULTY PART THAT PREMATURELY WEARS AND CAUSES THE MALFUNCTION. ALSO, THE ENTIRE FUEL PUMP INCLUDING THE SENDING UNIT AND FUEL LEVEL SENSOR NEEDS TO BE REPLACED, NOT JUST THE FUEL LEVEL SENSOR. *TR
