2004 GMC Yukon Electrical System Problems

Odometer Fraud. The contact purchased a 2004 GMC Yukon. The contact stated that while attempting to trade the vehicle in, the dealer discovered that there was a mileage discrepancy, per the Carfax report. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 165,563. The actual mileage could not be determined because the Carfax report displayed that the mileage had drastically fluctuated over the years. No other agency was contacted.

It is just like the the service bulletin out for the 2006 and later gmc sierra except it’s for a 2004 gmc Yukon slt 4x4 4.8L. It is going into reduced engine power mode and it has to do with the throttle actuator control module. Throws code P2108

My kids and I was on the interstate and all of sudden my yukon reduce engine power.Dropping to 30 in a speed zone of 70.I was very afraid for our safety and appreciate there concerns for reducing engine power to save the truck,but that's very dangerous. So I paid to replace the throttle body and gas pedal cause that was the codes for the problem. But it's still doing the same thing and I don't have money to keep buying parts.Plus it a gm problem and I really need some help with the fixture..

THE INSTRUMENT PANEL LIGHT INDICATING WHAT GEAR THE TRANSMISSION IS IN IS OUT AND THEREFORE DRIVER CANNOT TELL WHICH GEAR THE VEHICLE IS IN, AND EXTREME SAFETY HAZARD.

CLUSTER DASHBOARD FAILS TO LIGHT UP WHEN THE KEY TURNS ON THE VEHICLE. NONE IS THE DASHBOARD INDICATORS MOVE OR LIGHT UP, NOT ABLE TO SEE SPEED, MILES, GAS GAGE, ETC. IT TAKES 40 MINUTE INTO A DRIVE BEFORE IT TURNS ON RANDOMLY.

I WAS ON MY WAY HOME FROM WORK. I ENDED UP GETTING JUST A FEW RAIN DROPS SO I CLICK MY WIPER SWITCH ONE TIME, IT DIDN'T COME ON. ( PUZZLED ) SO I REPEATED TO GET TO WATER OFF WINDOW ,1 CLICK AT A TIME THE WIPERS DIDN'T COME ON UNTIL I WAS AT HIGH. OF COURSE , NOW THEY ARE ON HIGH AND RAIN IS GONE, NOW I CAN'T GET THE BLADES TO STOP IN THE OFF POSITION. WELL, I HAD TO PULL OVER I COULDN'T CONCENTRATE ON WHAT JUST HAPPENED TO MY WIPERS? AS WELL AS DRIVE. THIS HAPPENED ON JULY 10, 2019. I'VE CALLED GMC A COUPLE TIMES, 1ST TIME THEY JUST CLOSED NEXT TIME I DIDNT TRANSFER TO SERVICE DEPT . I JUST THINK , THERE SHOULD BE SOMETHING TO NOTIFY YOU , I JUST HAPPENED TO GET HOME BEFORE THE STORM HIT. I WAS ON A COUNTY ROAD WHEN IT HAPPENED. THANK YOU FOR YOUR TIME.

The contact owns a 2004 GMC Yukon. The contact stated while driving 45 MPH, the vehicle started losing motive power. The check engine warning light and another unknown warning light were illuminated, and a message was displayed that the gas port was reducing power. On a separate occasion, the vehicle started to lose motive power and then the vehicle started to shake. The vehicle was losing power and shaking until the vehicle was turned off. The vehicle was restarted and drove normally for six months without failure. The vehicle was taken to an independent mechanic where it was diagnosed with throttle body failure; however, the failure persisted. The vehicle was repaired but the failure persisted three more times with different diagnoses. The vehicle was taken to other independent mechanics however, the cause for the failure was not yet determined. The vehicle was not repaired for the most recent failure. The dealer was not made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 123,000.

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.

STABILITY CONTROL DISABLED COMES ON WITH ENGINE POWER REDUCED. THIS HAPPENED AS I AS DRIVING IN THE HIGHWAY. SPEED DRASTICALLY REDUCED FORM 65 TO 10 MPH. I COULD HAVE BEEN KILLED. GM IS AWARE OF THIS PROBLEM AND WILL NOT ACT UNTIL THERE'S A FATALITY BECAUSE OF THIS ISSUE. I AM AFRAID TO DRIVE THIS VEHICLE. NHTSA HAS RECEIVED NUMEROUS COMPLAINTS REGARDING THIS ISSUE AND HAS NOT ACTED. THE ELECTRICAL SYSTEM IS NOT CORRECT -THIS IS VERY DANGEROUS

SPEEDOMETER STICKS AT HIGHWAY SPEEDS AND REGISTERS AT LEAST 20 MPH HIGHER THAN ACTUAL SPEED AND NEEDLE FLUCTUATES SO YOU CAN NOT TELL HOW FAST YOU ARE GOING. FUEL GAUGE IS INACCURATE. BOTH ARE SAFETY CONCERNS. AT 120,000 MILES I AM BEYOND GM'S EXTENDED WARRANTY. SHOULD BE RECALLED AND FIXED.

THIS IS THE 2ND GM ALL TERRAIN VEHICLE I HAVE OWNED THAT THE SPEEDOMETER QUITS WORKING AFTER 50000 MILES . WHEN I RESEARCH ON MINE THERE ARE A BUNCH OF OWNERS THAT ARE COMPLAINING ABOUT THE SAME THING. AND IT'S THE INSTRUMENT PANEL THAT NEEDS TO BE CHANGED

TL* THE CONTACT OWNS A 2004 GMC YUKON. WHILE THE VEHICLE WAS IN PARK, THE REAR AIR CONDITIONER STOPPED BLOWING AIR. THE CONTACT, WHO WAS AN INDEPENDENT MECHANIC, DIAGNOSED THAT THE ELECTRICAL CONNECTION LOCATED BEHIND A PLASTIC PANEL IN THE HOOD LATCH WAS OVERHEATED BY THE ELECTRICAL WIRES. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE WAS NOT REMEDIED. THE FAILURE MILEAGE WAS APPROXIMATELY 126,000.

TL* THE CONTACT OWNS A 2004 GMC YUKON. WHILE THE VEHICLE WAS STATIONARY, WATER ENTERED THE HVAC SYSTEM AND CAUSED THE BLOWER RESISTER MODULE TO CORRODE. AS A RESULT, THE WIRING HARNESS HEATED UP, WHICH COULD HAVE POTENTIALLY CAUSED A FIRE IN THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS 145,000.

THE INSTRUMENT CLUSTER IS FAULTY DO TO BATTERY DRAIN. THIS PROBLEM PERSISTS WITH A MAJORITY OF TRUCKS AND SUV'S OF THE SAME GENERATION AS MY 2004 GMC YUKON DENALI XL. THE COST FROM THE DEALER TO REPLACE THIS PART IS APPROXIMATELY $2000. THERE ARE AFTERMARKET INSTRUMENT CLUSTER TO REPLACE THIS PART AT A COST OF ALL MOST $600. THIS REQUIRES PROGRAMMING BY THE DEALER FOR A COST OF ANOTHER $500+ ONLY TO HAVE THE SAME ISSUE REPEAT IT SELF AT LATER DATE.

SURGE HAPPENS WHILE DRIVING, THEN ENGINE LIGHT COMES ON, DECREASED ENGINE POWER OCCURS, TRACKTION STABILITY INDICTORS COMES ON. CAR LOOSES POWER. I HAVE TO PULL OVER OFF THE ROAD, PUT INTO PARK,CUT IGNITTION OFF, WAIT A FEW MINUTES AND THEN RESTART THE CAR. THIS COULD HAPPEN SEVERAL TIMES WHILE DRIVING.THE VEHICLE IS IN MOTION AND THIS IS A DRIVING HAZARD AND BIG SAFETY ISSUE, IT HAS HAPPENED ON CITY STREET AND ON A HIGHWAY. IT HAPPENS DAILY.

MY 2004 YUKON HAS AT LEAST THREE MAJOR LEAKS IN THE BRAKE LINES CAUSED BY CORROSION. RESEARCH FOUND THAT THIS DEFECT WAS IDENTIFIED SHORTLY AFTER THE VEHICLES WERE SOLD NEW BUT REFUSED TO ISSUE RECALLS. I WAS IN A NEAR ACCIDENT WHEN MY BRAKES WENT COMPLETELY TO THE FLOOR SUDDENLY. ALSO THE STABILIZER SYSTEM FAILS WITHOUT NOTICE AND THE DASH INSTRUMENT CLUSTER (GAS GAUGE, TEMP GAUGE, VOLTAGE AND OIL PRESSURE GAUGES WORKS ON AND OFF.

THE ENGINE LIGHT CONSTANTLY STAYS ON AND I'VE TAKEN IT TO A MECHANIC BUT IT COMES RIGHT BACK ON AGAIN. THE GAS GAUGE DOESN'T WORK PROPERLY. WHEN YOU FILL THE TANK TO FULL THE ARROW ONLY GOES TO THE HALFWAY MARK.

MY HUSBAND AND I PURCHASED A 2004 GMC YUKON FROM A LOCAL DEALERSHIP HERE IN LOUISVILLE KENTUCKY IN 2007 AND NOT TO LONG AFTER PURCHASING THE VEHICLE SOME OF THE GAUGES STOPPED WORKING. MY HUSBAND CONTACTED THE DEALERSHIP AND WAS TOLD TO BRING THE VEHICLE IN TO ONE OF THEIR SERVICE CENTER WHICH THEY LOOKED AT IT AND STATED THEY COULDN'T FIND NOTHING WRONG WITH IT. MY HUSBAND EXPLAINED THE GAUGES WOULD SOMETIMES STICK/QUITE WORKING WHILE DRIVING THE VEHICLE AND SOMETIMES WHEN STARTING THE VEHICLE AND HE WOULD SOMETIMES HAVE TO TAP ON IT TO TRY TO GET IT TO WORK AGAIN. TIME WENT ON AND IT GOT WORSE AND MY HUSBAND TOOK THE VEHICLE TO A CERTIFIED LOCAL MECHANIC AND HE TOLD HIM THE INSTRUMENT PANEL/CLUSTER NEEDED TO BE REPLACED. WE PAID FOR A REPLACEMENT AND SHORTLY AFTER THE REPLACEMENT IT STARTED DOING THE SAME THING THE OTHER PANEL DID. ALL THE GAUGES STOPPED WORKING AND WE HAVE TO TAP ON IT TO GET IT TO WORK AND NOW IT HAS GOTTEN EVEN WORSE AND I FEEL THAT THERE SHOULD BE A RECALL ON THESE BECAUSE WHY SHOULD WE CONTINUE TO SPEND OUR MONEY ON GETTING REPLACEMENTS AND THEY DO THE SAME THING. THERE MUST BE A DEFECT IN THESE PANELS. I HAVE CONTACTED GM REGARDING THIS ISSUE AND THEY STATED THERE WAS A SERVICE WARRANTY ON THE PANEL BUT IT EXPIRED IN 2011. I THEN STATED THAT WE DIDN'T KNOW ANYTHING ABOUT THE SERVICE WARRANTY BECAUSE WE NEVER RECEIVED ANYTHING IN THE MAIL AND THEY STATED THE SERVICE WARRANTY WAS MAILED OUT TO THE PREVIOUS OWNERS OF THE VEHICLE AND WE MUST NOT HAVE REGISTERED OUR VEHICLE CORRECTLY WITH THE DMV (DEPARTMENT OF MOTOR VEHICLE) WHICH I DON'T SEE HOW THAT IS POSSIBLE WHEN WE RECEIVE A NOTICE IN THE MAIL EVERY YEAR TO RENEW THE REGISTRATION ON THE VEHICLE WE ARE CURRENT EVERY YEAR SO I DON'T UNDERSTAND WHY WE DIDN'T RECEIVE THE NOTICE REGARDING THE SERVICE WARRANTY IN THE MAIL. *TR

TL* THE CONTACT OWNS A 2004 GMC YUKON DENALI. THE CONTACT STATED THAT THE SPEEDOMETER FAILED AND PREVENTED THE CONTACT FROM KNOWING HOW FAST THE VEHICLE WAS TRAVELING. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER STATED THAT THE WARRANTY ON THE SPEEDOMETER CLUSTER REPLACEMENT ENDED IN 2010. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 105,000.

TACHOMETER GAUGE NO LONGER FUNCTIONS, WRONG SPEED READING ON SPEEDOMETER AND OIL PRESSURE GAUGE READING TOO MUCH PRESSURE. FUEL GAUGE READING ADD FUEL WHEN I KNOW IT HAS MORE THAN "LOW". FUNNY HOW SPEEDOMETER WAS PEGGED OUT WHEN I WAS ONLY GOING 60. *TR
