2004 GMC YUKON XL 1500 Electrical System Problems

OUR YUKON ON NUMEROUS OCCASIONS WILL JUST DISPLAY REDUCED ENGINE POWER AND SPEED WILL DECREASE RAPIDLY. I HAVE PULLED OFF THE ROAD AND TURNED VEHICLE OFF REMOVED KEY WAITED A FEW MINUTES THEN STARTED THE TRUCK AND IT MAY RUN FINE OR MAY JUST CONTINUE TO HAVE REDUCED ENGINE POWER. BETWEEN THE TOW BILLS AND SHOP FEES I HAVE SPENT MORE THAN THE TRUCK IS WORTH. WE HAVE TAKEN TO THE SHOP AND SPENT OVER 5K FOR THEM TO STATE THE CAN NOT FIND AN ISSUE. THEY SAY THERE ARE NO CODES. THEN IT MAY OR MAY NOT RUN NORMAL FOR A SHORT PERIOD AND THERE IS NO PATTERN. IT HAS ON NUMEROUS OCCASIONS JUST COMPLETELY SHUT DOWN AND THEREFORE LOSS OF POWER STEERING AND BRAKES OCCURS. MAKING THIS VERY DANGEROUS. THE LAST TIME IT HAPPENED I WAS ON THE HIGHWAY TRAVELING AT 80 MPH. THE RESULT COULD HAVE BEEN DEADLY. I AM NOT SURE WHY GMC HAS DONE NOTHING TO FIX THIS ISSUE. I SAW SEVERAL OTHER BLOGS WITH THE SAME ISSUE. I AM THE ORIGINAL AND ONLY OWNER OF THIS TRUCK AND IT HAS BEEN WELL TAKEN CARE OF. I LOVED MY TRUCK UP UNTIL THESE ISSUES STARTED, PREVIOUS TO THIS THE TRUCK HAD A PARASITIC DRAW THAT AFTER 3 YEARS MY BROTHER FIGURED OUT NOT GM OR ANY OTHER MECHANIC. THAT WAS THE TEMPERATURE CONTROL MODULE FOR THOSE THAT MAY BE EXPERIENCING THIS ISSUE. IS THERE A WAY TO ENCOURAGE GM TO DO A RECALL? I NOW HAVE A USELESS TRUCK SITTING IN MY DRIVEWAY. IT IS NOT SAFE TO DRIVE.

DRIVING WHEN ENTIRE INSTRUMENT PANEL WENT BLACK. OFF/ON AT RANDOM. KNOCKING SOUND STARTED ABOUT THE SAME TIME. TOOK CAR IN TO BE CHECKED OUT. WAS TOLD BRAKE LINES WERE COMPLETELY RUSTED, AND NEEDED A NEW TRANSMISSION. WE PAID FOR REPAIR OF THE INSTRUMENT PANEL. TALKED TO OUR DEALERSHIP, HOLMAN IN CINCINNATI OH, ABOUT BREAKS. NO RECALL LISTED. THEY HAVE NEVER TOLD US THE BRAKE LINES WERE RUSTED. OFFERED US $150 BRAKE KIT TO DO OURSELVES (CANT DO) OR THEY CAN DO IT FOR $1500-2000. CAN'T AFFORD. IT SITS IN OUR DRIVEWAY, EPIC FAIL GMC. WE BOUGHT A HONDA.

BLOWER MOTOR RESISTOR FAILED IN THE TRUCK..WHEN THE CAR IS OFF MOTOR WILL RUN AND EVENTUALLY KILL THE BATTERY... MADE SEVERAL ATTEMPTS TO FIX IT BUT THE COMPANY NO LONGER MAKE THIS RESISTOR BECAUSE OF THE MALFUNCTION... SO NOT YEARS LATER STILL CAN'T FIX IT..CAN'T FIND THE RESISTOR AND NOW I HAVE NO AIR NO HEAT FOR 3 YEARS NOW. *TR

SPEEDOMETER FAILED TO FUNCTION, GAVE INCONSISTENT, INCORRECT SPEED. GM DEALER REPORTS THIS AS COMMON AND ACKNOWLEDGED BY GM IN THIS YEAR/MODEL, SUCH THAT GM EXTENDED WARRANTY TO 72,000 MILES. SINCE THIS WAS NOTICED PAST 72,000, GM OFFERS TO FIX, FOR A SUBSTANTIAL FEE. NOT KNOWING SPEED, OR BEING MISLED BY THE SPEEDOMETER, IS A SAFETY HAZARD. *TR

2004 GMC YUKON XL. GAS GAUGE OFTEN READS INCORRECTLY, MANY TIMES POINTING WAY PAST FULL OR STRAIGHT DOWN. THE VOLT METER HAS BEGUN READING INCORRECTLY, SHOWING IN EXCESS OF 20 VOLTS WHEN DRIVING AND IN EXCESS OF 16 VOLTS WHEN STOPPED WITH THE ENGINE OFF (KEY ON). THE SPEEDOMETER HAS STARTED TO READ INCORRECTLY OFTEN READING 0-10 MPH WHEN TRAVELING AT 30-40 MPH (GAUGED BY TRAFFIC). GM DID LOOK AT FUEL GAUGE ISSUE 2 YEARS AGO, BUT DIDN'T FIX THE PROBLEM. *TR

Mileage: 130,000

WE TOO HAVE HAD THE SPEEDOMETER ACTING UP. USUALLY AROUND 100KM. SOME DAYS IT WORKS BUT LATELY MOST DAYS IT DOES NOT WORK. GOING TO GET A NEW CABLE FOR IT TO SEE IF IT WILL CHANGE THE PROBLEM. *TR

TL*THE CONTACT OWNS A 2004 GMC YUKON XL 1500. THE CONTACT STATED THAT THE GAUGES ON THE INSTRUMENT PANEL DISPLAYED INACCURATE READINGS. THE DIALS IN THE GAUGES DO NOT MOVE WHEN THE VEHICLE IS BEING DRIVEN AT ANY SPEED. THE GMC MANUFACTURER STATED THAT ALL OF THE INSTRUMENT PANELS IN THE 2004 MODELS EXPERIENCED THE SAME FAILURE, AND THEY WOULD NOT REPAIR THE VEHICLE FOR FREE. THE DEALER STATED THAT THE INSTRUMENT PANEL FAILED AND WOULD BE THE CONTACT'S RESPONSIBILITY TO REPAIR. THE FAILURE MILEAGE WAS 75,000.

SPEEDOMETER FAILURE ON 2004 YUKON XL. WORKS FINE UNTIL SUDDEN FAILURE. SOME SPORADIC ATTEMPTS TO WORK AFTER BUT SPEEDOMETER CAN EASILY BE OFF BY 30-40 MPH. THIS IS A VERY COMMON PROBLEM WITH THESE GM VEHICLES AND IS KNOWN BY GM. APPARENTLY THE STEPPER MOTORS MOVING THE NEEDLES ARE FAILING. THE SPEEDOMETER IS USUALLY FIRST (LIKE MINE) FOLLOWED BY THE OTHER GAUGES IN THE INSTRUMENT PANEL AS THEY ARE ALL DRIVEN BY SIMILAR STEPPER MOTORS. A REASONABLE EXPECTATION IS TO HAVE THE SPEEDOMETER AND OTHER GAUGES LAST THE LIFE OF THE VEHICLE. A FAILURE HERE AND THERE IS UNDERSTANDABLE BUT WHEN YOU HAVE FAILURES AT THIS FREQUENCY GOING ON IT IS OBVIOUS THAT IT WAS UNDER DESIGNED. GM OFFERING TO STAND BEHIND ONLY IF IT FAILS UNDER 70K...MOST FAIL SHORTLY THEREAFTER. *TR

SPEEDOMETER GETS STUCK BETWEEN 50-60 MPH WHEN CAR IS OFF - FLUCTUATES AND CAN'T DETERMINE RATE OF SPEED WHEN DRIVING. *TR

2004 GMC YUKON XL - SPEEDOMETER DOES NOT WORK. WILL STAY ON ZERO ON ONE DAY, THEN PEG TO 140+ ON ANOTHER. I CAN MAINTAIN SPEED VIA TACH, BUT MY WIFE IS NOT FAMILIAR WITH THIS METHOD. VEHICLE HAS 54,000 MILES. *TR

THE SPEEDOMETER ON MY 2004 YUKON XL HAS FAILED. SOMETIMES THE DIAL STAYS AT 0MPH NO MATTER MY SPEED, SOMETIMES IT READS 120MPH NO MATTER THE SPEED, AND SOMETIMES IT READS 20MPH ABOVE AND BELOW THE ACTUAL SPEED LIMIT. GM HAS IDENTIFIED IS AS A PROBLEM BUT HAS NOT AGREED TO COVER ALL 2004 MODELS FOR THIS REPAIR. THIS BE SHOULD BE IDENTIFIED FOR A SYSTEM WIDE RECALL AND GM SHOULD BE REQUIRED TO PAY TO RECTIFY THIS SAFETY ISSUE. *TR

SPEEDOMETER STICKS ON MY 2004 GMC YUKON XL, IT CONTINUES TO HAPPEN ON A DAILY BASIS. I HAVE "RESET" THE SPEEDOMETER NUMEROUS TIMES BY TURNING THE IGNITION KEY ALMOST TO THE START POSITION BUT AFTER @ 10 MILES, IT WILL BE STUCK AGAIN. *JB

I STARTED HAVING PROBLEMS WITH THE SPEEDOMETER BECOMING ERRATIC ON MY 2004 GMC YUKON XL ABOUT 2 WEEKS AGO. NOTHING SEEMS TO FIX IT AND IT IS REALLY A SAFETY ISSUE. AS A MEMBER OF THE US MILITARY AND A FIREFIGHTER I FEEL I PUT MY LIFE ON THE LINE ENOUGH. I HAVE FOUND SEVERAL WEB-SITES WITH LITERALLY THOUSANDS OF PEOPLE WITH THE SAME PROBLEMS ON MANY DIFFERENT GM VEHICLES (MOSTLY TRUCKS AND SUV'S). THIS SHOULD BE A RECALLED ITEM BEFORE SOMEONE GETS HURT AND SUES GM OR IS THAT WHAT IT TAKES FOR A BILLION DOLLAR COMPANY TO GET THE POINT. I HAD THIS PART QUOTED TO ME AT $480 AND DON'T FEEL IT IS MY RESPONSIBILITY TO PAY FOR DEFECTIVE PARTS CONSIDERING ALL THESE OTHER PEOPLES PROBLEMS. *TR UPDATED 10/10/07 *TR
