2005 GMC ENVOY XL 370 Fuel System, Gasoline Problems

FUEL GAUGE SENSOR 2005 ENVOY XL DENALI. 70153 MILES. AFTER FUELING THE VEHICLE FUEL GAUGE REGISTERS EMPTY UNTIL ABOUT AN EIGHTH OF A TANK HAS BEEN USED THEN THE FUEL GAUGE WORKS JUST FINE. HAVE TO DISCONNECT THE POSITIVE BATTERY TERMINAL FOR APPX. TEN MINUTES TO GET THE SERVICE ENGINE LIGHT TO STOP ILLUMINATING. OCCURS EVERYTIME I FILL THE VEHICLE. IT CAUSES AN INACCURATE FUEL READING. TURNING IN TO DEALER TOMORROW 06-19-2013 FOR REPAIRS. CODE PRODUCED P0463. *TR

Mileage: 68,000

AIR CONDITIONER QUIT WORKING ON LEVEL 5, WOULD WORK ON LEVEL 1-4, LEVEL 5 WOULD KEEP TURNING OFF. SHORTLY AFTER THIS WITHIN THE SAME DAY I COULD SMELL SOMETHING BURNING COMING THROUGH THE AIR VENTS. MECHANICS NOTED AND SHOWED ME THAT THE RESISTOR PLUGS ON THE BACK HAD BURNED AND MELTED TOGETHER, THAT'S WHAT WAS CAUSING THE BURNING SMELL. NEEDED A NEW RESISTOR, PIG TAIL, AND BLOWER. ALSO MY FUEL GAUGE AND RPM ARE BROKE, HAVE NOT BEEN WORKING FOR THE PAST 3 YEARS. *TR

Mileage: 150,000

FUEL GAUGE DOES NOT WORK. I WILL FILL UP THE TANK AND TURN ON THE CAR AND IT READS LOW FUEL AND THE INDICATOR LIGHT COMES ON. THEN I CAN BE DRIVING AND IT WILL JUMP UP TO PAST 1/4 TANK THEN SLOWLY GO DOWN TO E AND READ LOW FUEL.

Mileage: 75,300

THE FUEL SENSOR ON MY VEHICLE SWINGS WILDLY FROM EMPTY TO FULL EVEN WHEN THE FUEL TANK HAS JUST BEEN FILLED. THIS RESULTS IN THE CHECK ENGINE LIGHT TO CONSTANTLY BE ON. I AM UNABLE TO DETERMINE HOW MUCH GAS IS IN THE CAR DUE TO THE FAULTY SENSOR. I HAVE CHECKED THE INTERNET AND THIS APPEARS TO BE A WIDESPREAD PROBLEM THAT HAS BEEN REPORTED FOR YEARS. I CALLED GM AND THEY TOLD ME THAT THEY HAVE KNOWN ABOUT THE PROBLEM AND WILL COVER 50% OF THE COST ONLY IF I TAKE IT TO A GM DEALER AND THAT MY PORTION OF THE COST WOULD BE BETWEEN $500 - $600 DOLLARS. THEY WOULD NOT COVER ANY OF THE COST IF I TAKE IT TO MY LOCAL MECHANIC. THIS PROBLEM HAS BEEN KNOWN BY GM FOR YEARS AND THEY SHOULD HAVE ISSUED A COMPLETE RECALL TO REPAIR THE DEFECTIVE PART(S). *TR

Mileage: 89,500

AFTER FILLING FUEL TANK, SENSOR WENT TO EMPTY IMEDIATELY. CHIMES ACTIVATE AND FUEL GAUAGE READS EMPTY.

FAULTY FUEL GAUGE WENT OUT AGAIN FOR THE SECOND TIME. FIRST TIME IT HAPPEN THE VEHICLE WAS UNDER WARRANTY. THIS TIME IT IS NOT COVERED. WE HAVE TAKEN THIS TRUCK TO THE SHOP TWICE TO WORK ON THE DASH BOARD INSTRUMENT CLUSTER.(OIL, BATTERY , FUEL). *TR

Mileage: 108,500

MY FUEL GAUGE STOPPED WORKING IN MY 2005 ENVOY AT APPROXIMATELY 40,000 MILES. THE FUEL GAUGE INDICATES THAT THE CAR IS OUT OF FUEL AFTER FILL THE TANK FULL. I HAVE NOTICED NUMEROUS COMPLAINTS ABOUT THIS PROBLEM AND HAVE ALSO RECEIVED A LETTER FROM GM STATING THAT THEY ARE AWARE OF THE PROBLEM AND WILL COVER UP TO 50% OF REPAIR AS MY WARRANT HAS EXPIRED. THE PROBLEM WITH ONLY COVERING 50% IS PAYING WITH FOR MY HALF OF THE REPAIR. I HAVE BEEN UNABLE TO COME UP WITH APPROXIMATELY THE $200 FOR THE REPAIR THEREFORE UNABLE TO HAVE IT REPAIRED. I SPOKE WITH GM CUSTOMER SERVICE AND THEY INFORMED ME THAT WAS MY OPTION. WHEN I ASKED WHY THERE HAS NOT BEEN A RECALL ON THE PROBLEM THEY INFORMED ME THAT I SHOULD CONTACT THE NHTSA. MY CONCERN IS THAT I LIVE IN A STATE WITH COLD WEATHER THAT REQUIRES THAT CAR TO WARM UP PRIOR TO DRIVING. SO I WAS KEEPING TRACK OF MY MILEAGE KNOWING WHEN I NEEDED TO FILL UP WITH GAS. ALTHOUGH, THIS WILL NOT BE ACCURATE IN WINTER AND AFRAID THAT MY SPOUSE (PRIMARY DRIVER OF THIS VEHICLE) WILL GET STRANDED ON THE ROAD. I HOPE IF/WHEN THIS HAPPENS IT IS NOT DURING A SNOW STORM WHERE AN AUTO ACCIDENT WILL THEN BECOME LIKELY. WHEN TALKING TO GM ALONG WITH THE FUEL SENSOR I EXPRESSES CONCERNS ABOUT OTHER ISSUES THAT I HAVE BEEN HAVING. FOR EXAMPLE, MY LICENSE PLATE LIGHT STOPPED WORKING, CHANGED THE BULB AND CHECKED THE FUSES AND STILL DOES NOT WORK; ALONG WITH HEAT ISSUES AND WAS INFORMED TO TAKE IN FOR DIAGNOSIS. *TR

FUEL SENSOR, LOCATED IN GAS TANK, HAS FAILED. NO MATTER HOW MUCH GAS IS IN THE TANK, BE IT FULL, HALF FULL, OR LESS, THE SENSOR BELL RINGS AND THE GAUGE REGISTERS EMPTY. THIS ALSO CAUSES THE CHECK ENGINE LIGHT TO COME ON. GMC SHOULD RECALL, AS THIS IS VERY DANGEROUS. I THOUGHT I HAD MORE FUEL BUT RAN OUT OF GAS ON A MAJOR ROAD, THANKFULLY NO ACCIDENT. GMC HAS ADMITTED THERE IS A PROBLEM AND HAS AGREED TO PAY 50% OF REPAIRS, BUT THIS IS ONLY DONE UNDER A VEHICLE WARRANTY EXTENSION, NOT RECALL. *TR

Mileage: 62,000

FUEL GAUGE READINGS ARE INACCURATE, DEALER WANTS TO REPLACE THE GAUGING SYSTEM IN THE TANK AT CONSUMERS COST. I BELIEVE IT IS A KNOWN PROBLEM AND SHOULD BE A WARRANTIED ITEM. *TR

MY 2005 GMC ENVOY SL ONLY HAS 47,000 MILES. I EXPERIENCED DASH ELECTRONICS CONCERNING WARNING INDICATOR LIGHTS ("POWER TRAIN COOLOING FAN AT 46,000 MILES") AND GAS TANK LEVEL GAUAGE STOPPED WORKING AT 40,000 MILES. I HAVE BEEN TOLD THAT THIS ISSUE RELATED TO AN OVERALL SENSOR PROBLEM AND WILL EFFECT THE HEADLIGHTS AND OTHER SAFETY RELATED ISSUES. *TT

TL* THE CONTACT OWNS A 2005 GMC ENVOY XL 370. THE CONTACT STATED THAT AFTER REFUELING THE TANK, HE NOTICED THAT THE FUEL GAUGE WOULD READ IMPROPERLY. THE VEHICLE WAS NOT INSPECTED BY A DEALER NOR REPAIRED. THE MANUFACTURER WAS CONTACTED THROUGH EMAIL AND HAD NOT YET REPLIED. THE FAILURE MILEAGE WAS APPROXIMATELY 49,000. THE VIN WAS UNAVAILABLE. UPDATED 09/29/2011 *LN *TR

FUEL GAUGE NOT READING CORRECT FUEL LEVEL. VEHICLE READS FULL ONE MINUTE AND EMPTY THE NEXT. VEHICLE HAS STALLED WHILE DRIVING. THIS WAS FIXED ONCE UNDER WARRANTY AND THIS IS THE SECOND TIME IT HAS OCCURRED I AM THE ORIGINAL OWNER. THE DEALERSHIP WILL NOT COVER THE REPAIR. I UNDERSTAND THAT GMC IS BEING INVESTIGATED BY YOUR ORGANIZATION FOR THIS ISSUE AND I WOULD LIKE TO BE ADDED TO NHTSA ACTION NUMBER: PE11014 AS PART OF MY COMPLAINT. *KB

IN 2008, OUR VEHICLE'S GAS GAUGE WOULD FLUCTUATE ON THE AMOUNT OF GAS. WE WOULD FILL IT UP AND THE GAUGE WOULD SHOW FULL BUT AS SOON AS WE WOULD START DRIVING WOULD DROP DOWN TO EMPTY AND EVENTUALLY AS OF TODAY WHEN WE FILL OUT VEHICLE UP ALL THE WAY, THE GUAGE ONLY SHOWS LESS THAN A 1/4 FULL THEN DROPS TO EMPTY. AFTER FILLING UP THE GAS TANK AND THE GAUGE SHOWING FULL AND DROPPING TO 1/4 FULL THEN I RAN OUT OF GAS WITH MY CHILDREN IN THE VEHICLE ON THE HIGHWAY, CAUSING MY GMC ENVOY TO SHUT DOWN AND MY STEERING WHEEL TO LOCK UP, LUCKILY I WAS ABLE TO STEER OFF TO THE SHOULDER WITH MUCH FORCE TO THE WHEEL. AS OF TODAY, OUR GAUGE NO LONGER RISES TO SHOW ANY SORT OF AMOUNT OF FUEL IN THE TANK. WE USE THE GAS USED ON THE DASH TO KEEP TRACK OR MILEAGE TO TRACK WHEN WE NEED TO FILL UP AND MAKE SURE WE DON'T GET DOWN TO CLOSE TO EMPTY. WE HAVE NOT FIXED THIS PROBLEM BECAUSE WE HAVE READ SO MANY COMPLAINTS THAT THERE SHOULD BE A RECALL MADE BY GMC. I HAVE CALLED GMC AND ASKED IF THERE WAS A RECALL FOR OUR VEHICLE AND TO MY SURPRISE NONE! I BELIEVE GMC NEEDS TO CORRECT THEIR MANUFACTURER DEFECT! *TR

PROBLEM WITH SEVERE FLUCTUATIONS OF FUEL GAUGE. RESEARCH SHOWS YOUR ONGOING INVESTIGATION # IS DP10001. UPON FILLING TANK TO APROX. TANK THE GAUGE SUDDENLY STARTED GOING WILD AND WITHIN 1 MILE OF DRIVING THE "CHECK ENGINE LIGHT" APPEARED. AFTER INVESTIGATING NUMEROUS ON-LINE RESOURCES IT IS CLEAR THAT THIS PROBLEM IS NOT ONLY LIMITED TO THIS VEHICLE BUT IS A SERIOUS PROBLEM IN THE GM LINEUP. DEALERSHIP REPAIR COSTS ARE ESTIMATED IN THE $800.00 TO $1000.00 RANGE. THIS IS UNACCEPTABLE FOR A PROBLEM THAT GM KNOWS TO EXIST YET REFUSES TO TAKE ANY UNILATERAL ACTION ON. *KB

I HAVE A 2005 GMC ENVOY. THE GAS GAUGE HAD STARTED HAVING PROBLEMS AT 60,000 MILES. IT COMPLETELY STOPPED WORKING AT 77,000 TO 80,000 MILES. I BOUGHT THE CAR USED IN 2008 WITH ONLY 45,000 MILES. MY JOB HAS ME ON THE HIGHWAY A LOT. I TRIED TO ESTIMATE THE MILES. BUT THIS IS VERY DANGEROUS I HAVE RAN OUT OF GAS ON HIGHWAY 820 AT 260 MILES AFTER FILLING UP. I RAN OUT ON HIGHWAY 30 AT 320 MILES. IN THE COUNTRY ON PRIVATE GOVERNMENT PROPERTY WITH NO ONE TO BE FOUND AT 150 MILES, EVERY TIME I COMPLETELY FILLED THE CAR UP WITH GAS BEFORE RESETTING THE FUEL GAUGE. I CAN NOT AFFORD TO GET IT FIXED. I CAN NOT TRADE THE CAR IN. I AM A SINGLE MOTHER TWITH THREE CHILDREN THAT HAS BEEN BLESSED SO FAR TO RUN OUT WITH OUT THEM IN THE CAR. I DID REALIZE SO MANY OTHERS WERE HAVING THE SAME PROBLEM. *TR

FUEL GAUGE MALFUNCTIONS AND WILL NOT WORK PROPERLY. WHEN VEHICLE IS FILLED TO FULL TANK LEVEL, THERE IS A CLICK SOUND AND THE GAUGE GOES ALL THE WAY TO THE EMPTY POSITION, THEN WARNING LIGHT AND VERY LOW FUEL INDICATOR LIGHT COMES ON. THIS IS THE 2ND GM VEHICLE I HAVE HAD PROBLEMS WITH. ONCE THE WARRANTY EXPIRES EVERYTHING STARTS TO GO WRONG SUCH AS FUEL PUMP/SENSOR, RADIATOR/FAN MOTOR, A/C, FRONT WHEEL BEARINGS. THE MORE I TRY TO MAINTAIN THESE VEHICLES THE MORE PROBLEMS. I WILL PURCHASE A HONDA, NISSAN, TOYOTA NEXT TIME. *TR

TL*THE CONTACT OWNS A 2005 GMC ENVOY XL 370. AFTER ADDING FUEL TO THE VEHICLE TO ITS CAPACITY THE FUEL GAUGE DID NOT DISPLAY THAT THE TANK WAS FULL. THE CONTACT STATED THE FUEL GAUGE WOULD THEN DISPLAY VARIOUS IMPROPER READINGS.

I HAVE A 2005 ENVOY AND I AM HAVING ISSUES WITH THE FUEL GAUGE AND THE SPEEDOMETER CLUSTER. I FILL UP THE TANK AND IT DOES NOT READ FULL, IT CONTINUES TO READ EMPTY. WHILE DRIVING MY SON BACK TO SCHOOL WITH MY THREE SMALL CHILDREN IN THE CAR THE SPEEDOMETER JUST STOPPED WORKING. IT WAS SHOWING THAT I WAS GOING 120 MILES WHEN I WAS ONLY GOING 40 ISH. THE OTHER THING THAT SHOCKS ME IS THAT THERE HAS NOT BEEN A RECALL ON THESE ISSUES. IT HAS TO BE SOME SORT OF DEFECT BECAUSE THERE ARE SO MANY CONSUMERS WITH THE SAME ISSUES. *TR

GAS GAUGE MALFUNCTIONS ON MY 2005 GMC ENVOY XL. FUEL LEVEL WAS AT HALF A TANK WHEN I DECIDED TO TOP IT OFF BEFORE A SNOWSTORM HIT. GAUGE READ FULL BUT ONCE I STARTED DRIVING IT STARTED TO DECREASE AND NOTICED THE REMAINING MILES LEFT WERE ALSO DECREASING UNTIL LOW FUEL LIGHT CAME ON. PUT CAR IN PARK AND IT STARTED RISING AGAIN. DROVE AND IT WOULD GO UP AND DOWN. PARKED OVERNIGHT AND RESTARTED THE NEXT DAY AND GAUGE READ LOW FUEL AND INDICATOR LIGHT WAS ON. DROVE A LITTLE THEN GAS LEVEL WENT TO NORMAL AND STARTED FLUCTUATING. THIS HAS NOW HAPPENED FOR ABOUT A WEEK AND A HALF. *TR

THE FUEL GAUGE BECAME ERRATIC. THE FIRST THING THAT HAPPENED WAS WHEN THE FUEL TANK WAS FILLED, THE GAS GAUGE WENT TO EMPTY AND THE FUEL LIGHT CAME ON AS IF THERE WERE NO FUEL. IT REMAINED THAT WAY FOR SOME TIME. IT THEN WOULD FLUCTUATE WILDLY UNTIL A LARGE AMOUNT OF GAS HAD BEEN USED. *TR

Mileage: 72,000

RAN OUT OF GAS MULTIPLE TIMES, DUE TO THE GAS GAUGE NOT WORKING. RESEARCHED ISSUE ON THE INTERNET AND NOTICED MULTIPLE DRIVERS WITH SAME ISSUE. GAS GAUGE DOES NOT READ CORRECT AMOUNT OR CONTINUOUSLY "EMPTY". HAVE HEARD INSTANCES OF OTHER DRIVERS WITH RUSTED/ERODED FUEL GAUGE SENSOR IN THE GAS TANK, CAUSING INACCURATE GAS GAUGE. HAVE BEEN STUCK IN DANGEROUS PLACES AFTER RUNNING OUT OF GAS. *TR

FUEL GAUGE STARTED FLUCTUATING AFTER FILLING UP MY GAS TANK. THE ERROR CONSTANTLY GOT WORST AND WORST UNTIL THE GAUGE JUST STOPPED WORKING. THE YELLOW LOW FUEL LIGHT IS ILLUMINATED MOST THE TIME AND THE NEEDLE SITS ON EMPTY EVEN WHEN THE GAS TANK HAS JUST BEEN FILLED. WAS TOLD THE FUEL SENSOR IN GAS TANK WAS FAULTY AND TO REPLACE WOULD MEAN REPLACING THE WHOLE PUMP ASSEMBLY. THIS ALONE WITH PARTS AND LABOR WILL COST ALMOST $1000.00.

WE OWN A 2005 GMC ENVOY XL. WE PURCHASED IT WITH 45,000 MILES. NOW AT 49,500 MILES IT APPEARS THE FUEL GAUGE IS BROKEN. IT STARTED ABOUT 1,000 MILES AGO. IT SEEMED IT WAS TAKING A LOT OF MONEY TO FILL THE TANK...MORE THAN USUAL. NOW EVEN WHEN WE FILL THE GAS TANK UP THE GAUGE STAYS ON EMPTY. THIS IS CAUSING US A PROBLEM BECAUSE WE DO NOT KNOW WHEN WE NEED TO FILL UP AGAIN. WE DO NOT WANT TO BE STRANDED. WE TOOK IT TO A DEALERSHIP AND THEY ARE TELLING US IT WILL COST ABOUT $800 TO FIX. PLEASE HELP. *TR

I HAVE OWNED MY 2005 ENVOY XL SINCE JUNE OF 2006. ONCE, I PASSED 36,000 MILES, I STARTED EXPERIENCE LOTS OF ISSUES WITH MY VEHICLE. I STARTED HEARING A KNOCKING NOISE IN THE REAR WHEN I WOULD TURN ON THE AC AND THE STEERING WAS OFF SOMEWHAT. I HAD THE STEERING FIXED FOR AROUND $400 BUT THE KNOCKING WAS GOING TO COST AROUND THE SAME AMOUNT. LESS THEN 10,000 MILES LATER, THE KNOCKING NOISE IS MORE PERSISTENT AND IS RELATED TO ISSUES WITH THE FUEL PUMP. MY GAS HAND WILL MOVE TO EMPTY WHEN I FILL THE TANK UP AND WILL NOT MOVE FORWARD FOR DAYS AT A TIME. TODAY, MY KIDS ARE COMPLAINING ABOUT THE AC NOT WORKING IN THE SECOND AND THIRD ROW SEATS. EVERYTIME I TURN THE CORNER IT SEEMS AS IF THERE IS ANOTHER PROBLEM WITH MY VEHICLE. *TR

Mileage: 38,000

2005 GMC ENVOY; THE FUEL GAUGE HAS BEEN ACTING CRAZY LATELY, SO I DECIDED TO RESEARCH THIS MATTER ON THE INTERNET, AND HAVE BEEN FINDING MORE AND MORE INCIDENTS WHERE THE GAS GAUGE EITHER STAYS ON EMPTY OR FLUCTUATES FROM EMPTY BACK TO FULL AND EVENTUALLY STOPS WORKING. AT APPX. 46,000MILES, MY GAS GAUGE STARTED DOING THE SAME AS PREVIOUSLY STATED, GOING FROM EMPTY TO FULL, AND SPORADICALLY REPEATING THIS EVEN IF THE FUEL TANK WAS FUEL. THE FUEL GAUGE BEING AT THE EMPTY LEVEL, BUT THE TANK IS FUEL, CAUSES A CONSTANT ALARM BELL TO GO OFF EVERY 10 SECONDS OR SO, EVERYTIME YOU GET IN THE VEHICLE. I HAVE BEEN TRYING TO FIND THE FUEL SENSOR TO REPLACE IT, BUT IT SEEMS THAT YOU HAVE TO PURCHASE THE HOLE FUEL PUMP ASSEMBLY WHICH RUNS AROUND $400, AND I AM NOT GOING TO REPLACE IT, IF EVERYONE THAT HAS A GMC ENVOY OR CHEVY TRAILBLAZER ARE ALL HAVING THE SAME PROBLEMS. FROM WHAT I GATHER, FROM MY RESEARCH, EVERYONE SEEMS TO HAVE THE SAME PROBLEM ON ALL FORUMS THAT I HAVE READ. MY VEHICLE ONLY HAS 51,000MILES ON IT RIGHT NOW, AND THIS PROBLEM HAS BEEN OCCURRING FOR ABOUT 3 MONTHS NOW. *TR

FUEL SYSTEM ISSUES FOR 2005 GMC ENVOY. FUEL GAUGE STOPPED WORKING PROPERLY IN LATE 2008. READS EMPTY ALL THE TIME REGARDLESS OF FUEL LEVEL. TODAY, 03/03/09, I EXPERIENCED A DEGRADED POWER SYMPTOM (AND WARNING ON THE DASH) RELATED TO THE FUEL SYSTEM. THE VEHICLE HAD TO BE SHUT DOWN AND RESTARTED TO CONTINUE DRIVING. *TR

Mileage: 80,000

GAS GAUGE READS EMPTY ALL THE TIME. LOW FUEL ALARM WILL GO OFF RANDOMLY EVEN THOUGH THEIR IS FUEL IN THE CAR. BECAUSE OF THIS I NEVER KNOW HOW MUCH GASOLINE I REALLY HAVE. I HAVE RAN OUT OF GAS AND BEEN STRANDED ON THE SIDE OF THE ROAD B/C OF THIS. *TR

AT APPROXIMATELY 50,000 MILES, THE FUEL SENDING UNIT ON MY 05 GMC ENVOY XL QUIT WORKING. THE FUEL GAUGE INDICATOR WILL FLUCTUATE BUT MOSTLY READS EMPTY AND EMITS LOW FUEL WARNING BUZZER EVEN AFTER I HAVE FILLED THE GAS TANK. I SPOKE TO A SERVICE WRITER AT A LOCAL DEALERSHIP ABOUT THE PROBLEM. HIS RESPONSE WAS THE DEALERSHIP SERVICE DEPARTMENT WOULD LOOK AT MY VEHICLE FOR ABOUT $300.00-NOT REPAIR THE PROBLEM-JUST DIAGNOSE IT. HE ALSO SAID THAT I WAS DRIVING THE VEHICLE TOO MUCH.*TR

2005 GMC ENVOY XL WITH 49000 MILES FUEL GAUGE NOT WORKING PROPERLY, WILL SHOW EMPTY AFTER FILLING UP THEN SHOW FULL. GAUGE WILL THEN SHOW 3/4 FULL THEN 1/2 FULL AFTER ONLY 10 TO 20 MILES. BEFORE 100 MILES GAUGE WILL DROP DOWN TO EMPTY FUEL LIGHT WILL COME ON AND BEEP. THIS WILL HAPPEN TILL TANK EMPTY, I NEVER KNOW HOW MUCH FUEL IS IN TRUCK. I HAVE READ THAT IT COULD BE FUEL CAP, SO I REPLACED IT BUT NO FIX. I HAVE RUN OUT OF GAS ON HIGHWAY A COUPLE OF TIMES ALREADY. THIS PROBLEM HAS BEEN THE SAME THROUGH 20 FILL UPS.CAN YOU HELP,FROM WHAT I HAVE HEARD RUNS FROM 600 TO 1000 DOLLARS. *TR

NOVEMBER OF 2006 WE REPLACED THE FUEL SENSOR THAT IS UNDER WARRANTY DUE TO WHEN I WOULD FILL UP THE GAS TANK THE GAUGE WOULD GO TO EMPTY AND WOULD EVENTUALLY MAKE IT TO FULL AFTER ABOUT 100 MILES DRIVEN. NOW A YEAR AND A HALF LATER THE SAME THING IS HAPPENING AND THE LOCAL DEALERSHIP HAS CONFIRMED IT IS A KNOWN ISSUE AND WOULD COST AROUND $1100 TO FIX THE ISSUE THAT SHOULD HAVE ALREADY OF BEEN FIXED THE FIRST TIME I TOOK IT IN. *TR
