INSTRUMENT CLUSTER. GAUGES RANDOMLY STICK OR FALSELY READ TO INCLUDE SPEEDOMETER. SOMETIMES IT WILL STICK AT A RANDOM SPEED. OTHER TIMES IT WILL PEG AT ITS MAX. UNKNOWN IF ODOMETER IS INVOLVED. SOMETIMES THEY RESET AFTER REPEATED START/OFF CYCLES. WAS COVERED UNDER A GM RECALL BULLETIN NO: 07187B, PAGE 8. CURRENT ODOMETER IS 145,369. SHOULD GM NOT REPAIR THIS AFTER THE WARRANTED PERIOD? THIS IS JUST AS DANGEROUS NOW THAN IT WAS AT 70,000 MILES. OIL PRESSURE GAUGE VERY RARELY READS CORRECTLY. I TRAILER TOW OFTEN AND CORRECT OIL PRESSURE IS IMPERATIVE AS IS A CORRECT SPEEDOMETER READING. ON THE TOP OF THE PAGE I DOWNLOADED FROM NHTSA IS THE NUMBER CSC-10026542-8984. PLEASE NOTE THAT THIS BEGAN TWO YEARS AGO WITH A FAULTY AMP GAUGE BUT WITHIN THE LAST SEVERAL MONTHS IT HAS NOW AFFECTED ALL GAUGES BUT THE FUEL GAUGE, WATER TEMP AND TRANSMISSION TEMP. POSSIBLY RELATED IS THE...

WHILE DRIVING ON THE HIGHWAY AND KEEPING UP WITH TRAFFIC, I NOTICED MY SPEED WAS 75MPH. SLOWING DOWN TO THE POSTED SPEED LIMIT I WAS SUDDENLY GETTING PASSED UP BY EVERYONE. IT WASN'T UNTIL I EXITED THE HIGHWAY AND WHILE WAITING AT A STOPLIGHT I NOTICED THE SPEEDOMETER WAS READING 10MPH (WHILE STANDING STILL). CHECKING GMC AND CHEVROLET FORUMS ONLINE, THIS SEEMS TO BE A COMMON PROBLEM AND A DEFINITE SAFETY CONCERN. THE READING ON THE SPEEDOMETER WHILE IN PARK NOW VARIES BETWEEN 10-20 MPH, AND I HAVE ABSOLUTELY NO IDEA HOW FAST I'M ACTUALLY TRAVELING WHILE DRIVING. I'VE MADE AN APPT WITH THE DEALER TO HAVE IT CHECKED OUT, AND I'M SURE THE REPAIRS WILL BE EXPENSIVE! *TR

TL* THE CONTACT OWNS A 2003 GMC YUKON XL. THE CONTACT STATED THAT ALL THE GAUGES ON THE INSTRUMENT PANEL FAILED TO FUNCTION. THE VEHICLE WAS TAKEN TO A DEALER. THE CONTACT WAS ADVISED THAT THE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED.

THE CURRENT MILEAGE WAS APPROXIMATELY 149,000.

REDUCED ENGINE SPEED WARNING LIGHT COMES ON AND DROPS TRUCK TO AN IDLE. I FEEL THIS IS VERY DANGEROUS IN TRAFFIC AND ON HIGHWAYS. MY MECHANIC HAS NOT BEEN ABLE TO LOCATE PROBLEM. ALL FORUMS AND ONLINE HELP HAS BROUGHT ME TO DEAD ENDS. THIS IS MY LAST RESORT, I BELIEVE GM KNOWS WHAT THE PROBLEM IS AND AM HOPING THEY WILL DO THE RIGHT THING AND RECALL BEFORE SOMEONE IS SERIOUSLY HURT OR KILLED FROM THIS ISSUE. *TR

DASH LIGHTS DON'T WORK BY HEATER LIGHTS. NEEDS A NEW CLUSTER AND CONTROL REPLACED. *TR

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

TL*THE CONTACT OWNS A 2003 GMC YUKON XL. THE CONTACT STATED THAT THE SPEEDOMETER IS ERRATIC AND BECOMES STUCK AT DIFFERENT SPEEDS. WHILE DRIVING 50 MPH, THE DIAL WOULD DROP DOWN TO 0 MPH AND DISPLAYS INACCURATE SPEEDS. THE CONTACT RECEIVED A RECALL NOTICE (RECALL NUMBER 07187) FROM GMC, WHICH STATED THAT THE RECALL WAS SEVEN YEARS OR 70,000 MILES. THE VEHICLE CURRENTLY HAS OVER 70,000 MILES; HOWEVER, NO FAILURES WERE OCCURRING AT THE TIME THE RECALL NOTICE WAS RECEIVED. THE DEALER STATED THAT THE VEHICLE WAS OUT OF WARRANTY FOR THE REPAIR. THE FAILURE MILEAGE WAS 111,000.

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...

2003 GMC YUKON XL COMPLAINT #1. SPEEDOMETER IS ERRATIC. ODOMETER READS ONLY 79,000 MILES. A FEW MONTHS AGO, AFTER STARTING THE VEHICLE THE SPEEDOMETER JUMPED TO 60 MPH WHICH CAUSED THE NEEDLE TO READ 120 AT THE ACTUAL 60. IF YOU SHUT OFF THE IGNITION AND RESTARTED THE CAR, THE NEEDLE WOULD DROP ABOUT 5 MPH EACH TIME. IF YOU REPEATED THIS PROCEDURE (STARTING ENGINE, SHUTTING OFF ENGINE) AFTER 10-12 TIMES THE SPEEDOMETER WOULD READ ZERO AGAIN. THIS HAPPENED SEVERAL TIMES. YESTERDAY AS I PULLED OFF THE HIGHWAY, WHERE THE SPEED IS 75 MPH, AND PULLED ONTO OUR LOCAL ROAD WHERE THE POSTED SPEED LIMIT IS 50, I NOTICED THAT I WAS HOLDING UP TRAFFIC ALTHOUGH THE SPEEDOMETER READ 50. I FELT AS IF I WAS NOT ACTUALLY DOING 50 SO I SPED UP EVEN THOUGH THE NEEDLE READ 65MPH. I PULLED OVER TO SEE IF INDEED THE SPEEDOMETER WAS...

SPEEDOMETER STICK AND JAMS. READS INCORRECT SPEEDS,OFF MY AS MUCH AS 100 MPH!. THIS I HAVE FOUND TO BE A COMMON PROBLEM WITH GMC'S, AND THEY KNOW ABOUT IT. *NM

THE SPEEDOMETER INCORRECTLY READS THE SPEED OF THE VEHICLE. WHEN THE VEHICLE IS TRAVELING 20 MPH, THE SPEEDOMETER REGISTERS 70MPH. WHEN THE VEHICLE IS SITTING STILL THE SPEEDOMETER IS ON 35MPH. GM DEALER THINKS THE PROBLEM IS THE GAUGE CLUSTER AND RECOMMENDS IT TO BE REPLACED AT A COST OF $400. THIS GAUGE CLUSTER HAS BEEN REPLACED IN THE PAST UNDER WARRANTY DUE TO INCORRECT FUEL LEVELS. *NM

MY SPEEDOMETER ON MY 2003 GMC YUKON KEEPS STICKING. READS 100 WHEN I'M ONLY DOING 30. *NM

DT*: THE CONTACT STATED ON THREE OCCASIONS WHILE DRIVING AT HIGHWAY AND FREEWAY SPEEDS OF 30- 75 MPH THE VEHICLE MADE A LOUD GRINDING NOISE FOLLOWED BY ANOTHER LOUD BANG. THE VEHICLE STALLED AND FILLED WITH WHITE SMOKE. THE VEHICLE WAS TOWED TO A LOCAL DEALERSHIP EACH TIME. THE ENTIRE A/C WAS REPLACED ON TWO OCCASIONS. ON ANOTHER OCCASION VARIOUS PARTS OF THE A/C WAS REPLACED. ON THREE OTHER OCCASIONS THE VEHICLE WOULD NOT START AND WAS TOWED EACH TIME. THE BATTERY WAS REPLACED A TOTAL OF THREE TIMES. THE PROBLEM STILL PERSISTS.

MY 2003 YUKON HAS A SPEEDOMETER PROBLEM. THE MPH WILL BECOME LOCKED IN ON SPEEDS THAT ARE NOT ACCURATE. TODAY I WAS DRIVING ACCORDING TO THE SPEEDOMETER 110 MPH, BUT ACTUAL SPEED LESS THAN 40 MPH. THIS PROBLEM HAS OCCURRED MORE THAN 40 TIMES IN THE LAST MONTH. WHEN I STOP THE VEHICLE THE SPEEDOMETER NEEDLE AT TIMES WILL NOT RESET TO 0 MPH. I HAVE HAD THIS PROBLEM FOR A WHILE, AND HAVE FOUND OUT THAT SOME FRIENDS WITH SIMILAR VEHICLES(GMC PICK UPS) HAVE THE SAME PROBLEM. I WAS ADVISED BY THE DEALER THAT THIS A PROBLEM THAT IS BECOMING MORE FREQUENT! *NM

I HAVE TAKEN MY 2003 GMC YUKON XL IN FOR SERVICE ON THE AIR CONDITIONER ON MORE THAN ONE OCCASION. I RECENTLY MOVED FROM MICHIGAN TO TENNESSEE AND WHILE LIVING IN MICHIGAN I NOTICES A SQUEALING NOISE WHENEVER I TURNED ON MY AC. THE NOISE WOULD LAST A FEW MINUTES AND THEN STOP. I ALSO NOTICED A RATTLING NOISE UPON ACCELERATION WHILE THE AC WAS ON. I TOOK IT TO THE DEALER IN MICHIGAN AND AT FIRST NOTHING WAS FOUND. I AGAIN TOOK IT TO A DEALERSHIP IN TENNESSEE AND WAS TOLD THAT IT WAS A RECYCLING SWITCH, AND IT WAS REPLACED. NOW, ALMOST I YEAR LATER THE SAME PROBLEM HAS OCCURRED BUT UNFORTUNATELY, MY VEHICLE IS NOW OUT OF WARRANTY (50,000 MILES) AND I AM NOW TOLD THAT THE AIR COMPRESSOR HAS COMPLETELY FAILED. IT WILL NOW COST ME OVER $1,000 TO REPAIR ON A CAR THAT IS LESS...

CONSUMER STATES THAT INSTRUMENT PANEL GETS EXTREMELY HOT DURING NORMAL VEHICLE OPERATION. CONSUMER CONCERNED ABOUT POSSIBLE FIRE HAZARD. PH COMPUTER MODULE WAS REPLACED AND THE INSTRUMENT PANEL IS NO LONGER HOT. MODULE ALSO CAUSED NO START CONDITION. *TT
