2004 GMC YUKON Electrical System Problems

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...

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..

GM IGNITION SWITCH RECALL: GMC REFUSES TO HONOR THE RECALL AND FIX THIS ISSUE ON BOTH MY SUV'S. I CAN'T BE PART OF THE CLASS ACTION UNTIL THESE REPAIRS HAVE BEEN MADE, WHAT A SCAM. I OWN 2 GMC YUKON'S SLT AND BOTH QUALIFY FOR THE RECALL WHICH I WAS NEVER NOTIFIED OF FROM GMC. NEITHER CAR EVER GOT REPAIRED. THE MANUFACTURE AND LOCAL DEALERSHIPS REFUSED TO DO THE REPAIRS AT NO COST. THIS IS AFTER I PAID THESE [XXX] OVER $1000 TO FIX THIS PROBLEM ON ONE OF MY SUV'S MANY YEARS AGO WHICH DID NOT GET FIXED BECAUSE THEY CLAIM THEY COULDN'T FIND WHAT WAS WRONG WITH MY SUV'S BUT THEY KNEW ALL ALONG. I WANT GM TO HONOR THEIR LEGAL OBLIGATIONS AND FIX MY SUV'S FAULTY IGNITION SYSTEM. I ONLY FOUND OUT THAT THERE WAS A RECAL FROM THE CLASS ACTION ATTORNEYS. GM NEVER NOTIFIED ME OF...

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.

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...

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.

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.

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 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...

TL* THE CONTACT OWNS A 2004 GMC YUKON. WHILE DRIVING AT AN UNKNOWN SPEED, THE INSTRUMENT PANEL FAILED TO DISPLAY THE CORRECT GAUGE LEVELS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE TECHNICIAN DIAGNOSED THAT THERE WAS AN ELECTRICAL FAILURE. THE VEHICLE WAS REPAIRED, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 70,000.

WHILE TRAVELING ON THE FREEWAY AT APPROXIMATELY 70MPH, THE SPEEDOMETER IN THE VEHICLE MALFUNCTIONED AND BEGAN STEADILY DECREASING UNTIL IT REACHED 0. LUCKILY I HAD MY GPS TO GO BY FOR MY VEHICLE SPEED, OTHERWISE I WOULD HAVE HAD KNOW CLUE OF HOW FAST OR SLOW I WAS GOING. THIS IS A MAJOR SAFETY CONCERN AND SHOULD BE A RECALL ON ALL VEHICLES REGARDLESS OF MILEAGE, OR DOES SOMEONE HAVE TO DIE FIRST!! *TR

TL* THE CONTACT OWNS A 2004 GMC YUKON. THE CONTACT STATED THAT THE REAR SEAT RADIO FUNCTION WAS NOT FUNCTIONING. THE CONTACT NOTICED THE CONSOLE WAS EXTREMELY HOT. THE DEALER WAS MADE AWARE OF THE FAILURE BUT A DIAGNOSTIC TEST WAS NOT PERFORMED. ALSO, THE CONTACT STATED THAT THE PASSENGER SIDE DAYTIME RUNNING HEADLIGHT BULB WAS REPLACED THREE DIFFERENT TIMES. THE CONTACT NOTICED THE LIGHT BULBS THAT WERE REMOVED WERE BLACK AND APPEARED MELTED ON THE BOTTOM. THE VEHICLE WAS NOT REPAIRED FOR THE RADIO FAILURE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 60.

TL* THE CONTACT OWNS A 2004 GMC YUKON. THE CONTACT STATED THAT THE INSTRUMENT PANEL WOULD FAIL SPORADICALLY. THE CONTACT TOOK THE VEHICLE TO DEALER AND WAS ADVISED THAT THE GEAR MECHANISM WAS DESIGNED TO FAIL OVER TIME. THE MANUFACTURER WAS AWARE OF THE ISSUE AND WAS OFFERING TO PAY FOR THE REPAIR ON VEHICLE WITHIN 70,000 MILES OR LESS. THE FAILURE MILEAGE WAS UNKNOWN AND CURRENT MILEAGE WAS 130,000.

TL*THE CONTACT OWNS A 2004 GMC YUKON. WHILE PARKED, THE CONTACT STARTED THE IGNITION AND THE CHECK ENGINE LIGHT ILLUMINATED. THE CHECK ENGINE LIGHT WOULD ILLUMINATE INTERMITTENTLY. THE CONTACT STATED THE SPEEDOMETER WAS ALSO FAILING. THE SPEEDOMETER WOULD BECOME STUCK AND AFTER A FEW DAYS WOULD FUNCTION NORMALLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TECHNICIANS INFORMED THE WARRANTY HAD EXPIRED AND THE CONTACT WOULD HAVE TO COVER COST OF THE REPAIRS AND DIAGNOSTIC. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 90,000.

FUEL GAUGE READING INACCURATELY. NEEDLE WENT WAY PAST THE FULL MARK INTO THE BLANK AREA ON THE BOTTOM OF THE GAUGE. ALSO, THE SPEEDOMETER WAS READING 120MPH WHEN I WAS PULLING OUT OF MY DRIVEWAY. I STUCK AT 70MPH WHEN I WAS STOPPED.

THE SPEEDOMETER IS ERRATIC, USUALLY SHOWING 130 MPH. THE OIL GAUGE AND GAS GAUGE HAVE NOW STOPPED WORKING AS WELL. WE CAN ONLY GAUGE OUR SPEED BY USING A GPS. IT HAS BEEN HAPPENING FOR ABOUT A YEAR AND WE HAVE OVER 100,000 MILES ON THE VEHICLE. *TR

UPON TAKING DELIVERY OF VEHICLE ERRATIC ELECTRICAL PROBLEM EXISTED. OFTEN ONLY THE FRONT DOORS WOULD LIKE, LEAVING THE BACK DOORS AND REAR DOOR UNLOCKED. OFTEN UPON INSERTING KEY IN IGNITION, DRIVERS SEAT WOULD ZOOM FORWARD PUSHING OCCUPANT AGAINST STEERING WHEEL. WHILE DRIVING, OUTSIDE REAR VIEW MIRRORS WOULD RETRACT FOR NO REASON. DEALER HAS NOT BEEN ABLE TO FIX THOUGH MANY SERVICE NOTES EXIST. LATELY, THE AMP GAUGE FAILED HOWEVER AMPERAGE IS NOT AFFECTED. NEXT THE SPEEDOMETER SHOWED 38 MPH WHILE NOT MOVING. IT IS TOTALLY NOW INOPERATIVE, VARYING FROM NEVER LEAVING ZERO TO SHOWING 80 WHILE GOING 20 MPH. SINCE I CANNOT TRUST THE ACCURACY OF ANY GAUGE, I HAVE NO IDEA HOW FAST I AM DRIVING OR ANY OF THE OTHER VITAL INSTRUMENT READINGS. *TR

I HAVE A 2004 GMC YUKON THAT HAS AN ERRATIC SPEEDOMETER. AT TIMES, IT WILL FREEZE UP. OTHER TIMES IT WILL DISPLAY THE INCORRECT SPEED INCLUDING FREEZING AT 0MPH. IT IS MY UNDERSTANDING THAT THIS IS A VERY COMMON COMPLAINT BY OWNERS OF VEHICLES CONTAINING THESE TYPES OF FAULTY INSTRUMENT CLUSTERS. MY VEHICLE HAS OVER 80,000 MILES ON IT AND IS NOT COVERED BY ANY SORT OF GMC WARRANTY AND/OR REPLACEMENT PLAN. THIS EQUIPMENT POSES A SAFETY THREAT AS I CANNOT DETERMINE THE SPEED OF MY VEHICLE AND MORE ACCURATELY INTERPRET FOLLOWING DISTANCE FROM OTHER VEHICLES. *TR

INACCURATE SPEEDOMETER READINGS INCLUDING COMPLETE FAILURE OF THE SPEEDOMETER ON THE INSTRUMENT PANEL. DRIVING AT HIGHWAY SPEEDS IN EXCESS OF 60MPH, SPEEDOMETER SHOWED 10MPH. *TR

MY 2004 GMC YUKON HAS BEEN TAKEN TO SEVERAL GMC SERVICE CENTERS TO TRY AND DIAGNOSE SEVERAL ELECTRONIC ISSUES. 1. THE RADIO AND AC UNIT WILL TURN ON FOR NO REASON AND BOTH UNITS ARE EXTREMELY HOT TO THE TOUCH. 2. THE FRONT DASH RESONATES WHEN THE VEHICLE IS AT A SLIGHT INCLINE OR DECLINE WHEN THE AC UNIT IS ON. 3. THE SPEEDOMETER WOULD OCCASIONALLY STOP WORKING AFTER RUNNING THE VEHICLE FOR ABOUT 30 MINUTES YET THE DEALERSHIP WAS NEVER ABLE TO DUPLICATE. IT HAS NOW STOPPED WORKING ALL TOGETHER. *NM

MY 2004 GMC YUKON STARTED HAVING SPEEDOMETER TROUBLES A FEW MONTHS AGO. SOMETIMES IT WOULD WORK JUST FINE, BUT SOMETIMES IT WOULD READ 120 MPH WHEN I WAS PARKED, OR SOMETIMES IT WOULD READ 0 MPH WHEN I WAS GOING ABOUT 65 ON THE HIGHWAY. SOME DAYS IT WOULD WORK JUST FINE, OTHER DAYS, IT WAS VERY OFF. IT GOT TO WHERE I COULD NOT RELY ON MY SPEEDOMETER TO TELL HOW FAST I WAS GOING. I HAD TO USE A GPS TO GET MY SPEED. *NM

"STABILITY SYSTEM DISABLED" WAS DISPLAYED PRIOR TO THE BRAKES BEING ENGAGED WITHOUT DRIVER INPUT. THE VEHICLE WAS TAKEN TO THE DEALER AND A 'YAW SENSOR' REPLACED. THE PROBLEM RETURNED WITHIN 20 MILES. A SECOND SENSOR WAS REPLACED ALONG WITH REPROGRAMMING. THE PROBLEM CONTINUES. DEALER STATES "GM HAS TOLD US TO DO NOTHING MORE". NO FURTHER EXPLANATION IS OFFERED BY THE DEALER OR GM "CUSTOMER ASSISTANCE". I BELIEVE THAT A VEHICLE THAT ACTIVATES BRAKES ON DRY PAVEMENT WITHOUT THE DRIVER'S FOOT ON THE PEDAL IS DANGEROUS.

2004 GMC YUKON SLT -- INSTRUMENT PANEL WHEN TRUCK WAS STARTED. ALL GAUGES (FUEL, BATTERY & WATER) BECAME INACTIVE. SHIFT INDICATOR NO LONGER WORKED AND I WAS UNABLE TO DETERMINE WHAT GEAR THE CAR WAS IN. AUDIO SYSTEM (CASSETTE, CD PLAYER AND RADIO) BECAME INOPERABLE. CAR TAKEN TO DEALERSHIP -- BECK & MASTEN NORTH IN HOUSTON. I WAS TOLD THAT THE BODY CONTROL MODULE WAS DEFECTIVE AND WOULD NEED TO BE REPLACED. PREVIOUS ISSUE WITH THE INSTRUMENT PANEL CLUSTER GOING OUT, CAUSING SPEEDOMETER TO BECOME INOPERATIVE. DEALER ADMITTED THAT THIS WAS A PROBLEM ON A NUMBER OF YUKONS. (I HAVEN'T SEEN THIS A A RECALL ON EITHER YOUR SITE OR GMC'S SITE.) GMC HAS VIOLATED FMVSS STANDARD NO. 101 AND PARTS 573 AND 577.
