2003 GMC Yukon Fuel System Problems

GAS GAUGE DOES NOT CORRECTLY REFLECT WHAT IS IN THE TANK, HAVE RUN OUT OF GAS OR COME CLOSE QUITE A FEW TIMES DUE TO INCORRECT READINGS, IT WILL SHOW 1/2 FULL AND DROP RAPIDLY WITHIN MINUTES TO EMPTY. I'VE TAKEN IT IN THEY SAID IT WAS THE GAUGE CLUSTER IN THE DASH SO THEY REPLACED IT, IT HAPPENED AGAIN, TOOK IT BACK IN AND OF COURSE AT THAT TIME IT WAS OUT OF WARRANTY THEY SAID THEY HAVE NOT HEARD OF ANY PROBLEMS AT THE DEALERSHIP IN REGARDS TO THIS PROBLEM AND THAT THEY ASSUME THE SENDING UNIT IS BAD AND WOULD REPLACE IT IF I PAID FOR IT, WHY THIS WASN'T DONE THE 1ST TIME UNDER WARRANTY IS BEYOND ME, BUT I'VE NOTICED ON THE NEWS THAT OTHER VEHICLES ARE HAVING SIMILAR PROBLEMS AND SEARCHING THE WEB I SEE I'M NOT ALONE. THEY NEED TO STEP UP AND FIX THE PROBLEM.

VEHICLE STALLS WHILE IN MOTION. FIGURED OUT IT MAY BE RUNNING OUT OF GAS DUE TO THE GAUGE NOT WORKING. NOW, IT STALLS WHEN IT ONLY HAS A HALF A TANK OF GAS, NOT COMPLETELY EMPTY. PUT 16 GALLONS OF GAS IN THE 30 GALLON TANK, TRUCK RUNS SMOOTH. REPLACED THE FUEL FILTER TWICE. REPLACED THE BATTERY, TESTED THE ALTERNATOR, RESULTS NO ALT. PROBLEM. CHECK ENGINE LIGHT ON, SPEEDOMETER IS OFF, GAS GAUGE IS OFF, AND THE REAR VIEW MIRROR DISPLAY LIGHTS GO ON AND OFF ERRATICALLY. BIGGEST PROBLEM IS WHEN I BREAK THE TRUCK WILL SHUT OFF. THIS HAS BEEN GOING ON SINCE NOV. 2010, WHEN WE REPLACED THE BATTERY AND QUIT USING A CERTAIN TYPE OF GAS IT SEEMED TO BE FINE. NOW, IT IS ACTING UP AND TODAY WAS THE FIRST INCIDENT SINCE EARLY DECEMBER. *TR

FUEL GAUGE ON 2003 YUKON WILL SHOW EMPTY THEN FULL RANDOMLY AND AFTER FUEL IS ADDED RANDOMLY (YUKON IS ON LEVEL GROUND). GAUGE ALSO STICKS. JANUARY 3, 2008, I TOOK THE YUKON TO THE DEALER. THEY COULD NOT DUPLICATE. IT HAS HAPPENED AGAIN DECEMBER 2, 2008. *TR

WHILE DRIVING AT 65 MPH, THE YUKON JUST SHUT DOWN AND THE BATTERY LIGHT CAME ON. GOT TO SHOULDER OF ROAD, PUT IT IN PARK, TURN OF THE IGNITION AND STARTED IT RIGHT BACK UP. DID IT AGAIN, 15 MINUTES LATER - SAME RESULTS. THE NEXT 7 TIMES, THE CAR AT LOW SPEED (15-20 MPH) STARTED ACTING LIKE IT WASN'T GETTING GAS AND RUNNING ROUGH, NOT PULLING. PULLED OF ROAD. WOULD TURN OVER AND TRY TO START AND IF IT STARTED, WAS VERY ROUGH. AFTER ABOUT 15 MINUTES, THE YUKON STARTED LIKE NOTHING WAS WRONG AND WOULD RUN FOR 10-15 MINUTES. THIS ALSO HAPPENED TO ME IN JUNE. TOOK TO AN INDEPENDENT MECHANIC WHO COULD FIND NOTHING WRONG. HAPPENED TO MY PARENTS IN 2006 IN THIS VEHICLE TRAVELING TO MISSISSIPPI. GMC DEALER COULD FIND NOTHING WRONG. CURRENTLY THE DEALER WANTS TO CHANGE THE FUEL PUMP. I HAVE RESEARCHED AND OTHERS WITH THIS PROBLEM HAVE REPLACED THE FUEL PUMP AND IT DOESN'T STOP HAPPENING. SPEEDOMETER JUST FAILED TOO. WONDER IF IT COULD BE AN ELECTRONICS/ELECTRICAL PROBLEM. *TR

MY 2003 YUKON XL (51,000 MILES) FLEX FUEL SENSOR IS ROTTING OFF THE VEHICLE. WAS TOLD IT IS NOT COVERED. IT IS SELF DESTRUCTING AROUND THE AREA WHERE THE FUEL LINES ENTER THE SENSOR. IF THE CORROSION CONTINUES IT WILL CAUSE FUEL TO SPRAY ALL OVER THE UNDERCARRIAGE. I AM AN ASE MASTER TECH. AND A VOCATIONAL AUTOMOTIVE INSTRUCTOR. I FEEL THIS COULD POSE A SEVERE SAFETY ISSUE. *NM

THE NEEDLES FOR MY SPEEDOMETER AND ENGINE TEMP. BOTH SIT IN THE 6 O'CLOCK POSITION AND ARE COMPLETELY INOPERATIVE. SPEEDOMETER HAS BEEN BROKE SINCE DECEMBER OF 2005 AND THE ENGINE TEMP GAUGE BROKE OCTOBER 2007. *TR

2003 YUKON XL WOULD DIE LIKE IT WAS OUT OF GAS WHEN IT STILL HAD AT LEAST 1/4 TANK OR IT WOULD NOT START WHEN IT HAD AT LEAST 1/4 TANK OF GAS BUT IF YOU ADDED 1 - 5 GALLONS OF GAS IT WOULD START. TOOK TO DEALER AND THEY SAID THE FUEL PUMP HAD LOW PRESSURE AND THEY REPLACED FUEL SENDING UNIT. SEEMS TO BE FINE NOW. DEALER STATED THEY HAD NOT SEEN ANY OTHER VEHICLES WITH THIS PROBLEM BUT I KNOW OF AT LEAST 4 OTHER GM SUV'S THAT ARE HAVING THE SAME PROBLEM IN THE SMALL TOWN THAT I LIVE IN

THE PASSENGER SIDE REAR TIRE BLEW OUT WHILE CONSUMER WAS TRAVELING AT 60 MPH.*AK AT 1,000 MILES THE VEHICLE'S FUEL PUMP FAILED WHILE DRIVING ON THE FREEWAY AT 65 MPH. *BF

2003 GMC YUKON DENALI XL ENGINE STALLED WHILE DRIVING. *MR THE FUEL PUMP FAILED. *SC *JB

THE CUSTOMER COMPLAINT AND REQUEST FOR REIMBURSEMENT FOR 2003 GMC YUKON.***NO ANSWER REQUIRED***. *MR (FAULTY SENDER WAS GIVING AN INACCURATE READING) THE VEHICLE STALLED AT 80 MPH. THIS MAY BE A COMMON PROBLEM IN THESE VEHICLES. THE VEHICLE REGISTERED 1/4 TANK AT THE TIME OF THE INCIDENT. THE FUEL SENDING MODULE WAS REPLACED. *SC *JB

I HAVE A 2003 GMC YUKON. IT NOW HAS 20,000 MILES. GM HAS HAD TO REPLACE THE FUEL PUMP TWICE SO FAR AND WILL HAVE TO EVERY TIME I RUN LOW ON GASOLINE. IT SEEMS THAT THE PUMP IS LOCATED IN THE GAS TANK AND THE PUMP DEPENDS ON THE TANK HAVING ENOUGH LIQUID TO KEEP THE ELECTRIC PUMP COOL. OTHERWISE IT OVERHEATS AND BURNS UP. I CAN'T BELIEVE SUCH DUMB ENGINEERING. I'M SURE THAT I AM NOT THE ONLY CONSUMER WHO HAS HAD THIS TROUBLE. THE SERVICE PEOPLE MAKE NO SECRET THAT YOU MUST KEEP AT LEAST A QUARTER TANK AT ALL TIMES TO KEEP THE PUMP FROM BURNING UP. *AK

COMPLETE LOSS OF POWER ON THE HIGHWAY WHILE DRIVING 65 MPH. *PH THE DEALER DIAGNOSED THE PROBLEM AS A FUSE AND FAULTY FUEL PUMP BUT COULD NOT GAURANTEE THAT THE PROBLEM WOULD NOT RECURR. *NM

DRIVING 60 MPH ON A 20 MILE BRIDGE, THE ENGINE FAILED (ENGINE LIGHT AND TRACTION CONTROL LIGHT WERE ON. NO POWER STEERING OR POWER BRAKES. NOTHING APPEARED TO BE OVERHEATED. 2 HRS LATER IT STARTED, 5 MINUTES LATER IT KILLED AGAIN. TOWED TO NEAREST DEALERSHIP. THEY ROAD TESTED IT AND CAR FAILED AGAIN. FOUND 1 BROKEN WIRE INSIDE WIRE INSULATION. REPAIRED. PICKED UP CAR AND IT FAILED 1 MILE LATER, TOOK IT BACK TO DEALERSHIP ON "REDUCED ENGINE POWER". THEY FOUND 2 MORE BROKEN WIRES. REPLACED HARNESS. ONE WEEK LATER IT HAPPENED AGAIN. AFTER BRIEF WAIT IT STARTED AND RAN FOR ANOTHER DAY UNTIL I COULD GET IT TO THE DEALERSHIP PURCHASED FROM. THEY COULD NOT FIND ANYTHING WRONG. TWO WEEKS LATER IT FAILED AGAIN. TOW TRUCK TOOK IT TO ANOTHER DEARLERSHIP. THEY CHANGED ANOTHER PART RELATIVE TO THE FUEL SYSTEM AND SAID IT "MAY" BE FIXED. I REFUSE TO PICK IT UP OR DRIVE IT AGAIN; IT'S DANGEROUS AND UNDEPENDABLE. HAVE ASKED GM FOR ANOTHER CAR AND I AM WAITING FOR THEIR RESPONSE. *JB

WHEN FILLING THE VEHICLE WITH FUEL A LEAK HAS DEVELOPED UNDERNEATH. CONSUMER HAS SCHEDULED AN APPOINTMENT WITH THE DEALER. *AK

2003 GMC YUKON WON'T START WITH A QUARTER TANK OF GAS. CONSUMER STATES THAT DEALER STATED THAT THEY WOULD BRING THE TANK DOWN AND REPLACE THE FUEL PUMP BUT THEY NEVER DID. *KB
