2004 GMC YUKON DENALI Electrical System Problems

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

FIRST THE AIRBAG WARNING LIGHT CAME ON. THIS HAS BEEN AN ONGOING ISSUE SINCE 2008. MY SPEEDOMETER REGISTERED THE WRONG SPEED. MY SETTINGS FOR THE SEAT AND MIRRORS QUIT WORKING OVER TIME.HOT AIR WOULD COME OUT OF MY VENTS WHEN THE AIR CONDITIONER WAS ON RANDOMLY. RADIO, NAVIGATION, HEAT, AIR CONDITIONER AND MIRRORS WOULD TURN ON/OFF RANDOMLY WITHOUT TOUCHING CONTROLS. THE LAST 3 YEARS WENT THROUGH 3 BATTERIES IN 3 YEARS. TESTS SHOWED AT LEAST 5 THINGS ARE ACTIVELY DRAINING BATTERY IN THE FUSE BOX. ISSUES HAPPENED MOSTLY WHEN CAR WAS ON BUT MIRRORS WOULD RANDOMLY MOVE WHEN CAR WAS NOT ON, VERY CREEPY.

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.

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.

THERE ARE SEVERAL COMPLAINTS, ON THE 2004 GMC DENALIS. IT'S LIKE IT STARTS SLOW YOUR GAUGES GO OUT. YOU HAVE NO IDEA HOW FAST YOU ARE GOING! THEN THE OIL, TEMP FOR ENGINE, AND TRANSMISSION. WHICH I HAD TO REPLACE. THEN THE BRAKES GET A MIND OF THEIR OWN. RECENTLY THE RADIO & LIGHTS ARE ACTING UP WHICH IS SCARY, I HAVE A 7 YR. OLD. THE HEAT IN THE BACK DOESN'T WORK FOR HER, SO I HAVE SEVERAL BLANKETS FOR HER. THE TELEVISION QUIT LONG AGO, IT WAS ONE OF THE REASONS WE BOUGHT THE CAR, SO KIDS COULD WATCH TELEVISION ON LONG TRIPS, OR WHENEVER. WE PAID A LOT FOR THIS VEHICLE, I WOULD THINK GMC WOULD STEP UP AND DO THE RIGHT THING AND CORRECT THE PRODUCT THEY STAND BY,AND ARE VERY PROUD OF. I WOULD LOVE TO JUST PURCHASE A NEW VEHICLE. I DO NOT HAVE...

DRIVING VEHICLE AT 30 MPH. LOST ALL POWER AND ENGINE. NO BRAKES, NO POWER STEERING, NO DASH LIGHTS, ENGINE QUIT RUNNING, NO EXTERIOR LIGHTS. PARKED VEHICLE IN PARKING LOT. NO POWER AT ALL. AFTER ABOUT 20 MINUTES OF WAITING VEHICLE STARTED AGAIN AND HAD MINIMAL ACCELERATION/POWER. *TR

AT APPROXIMATELY 1:54 PM I WAS LEAVING WORK AND I DIDN'T GET ABOUT 1,000 FEET WHEN I BEGAN TO SEE SMOKE COMING FROM THE CENTER CONSOLE AREA WHERE THE CIGARETTE LIGHTER WAS. I PULLED OVER INTO A GAS STATION AND TOOK THE CUP HOLDERS OUT TRYING TO SEARCH WHERE THE SMOKE WAS COMING FROM. I THEN SAW SMOKE COMING FROM THE VENTS ON THE DASHBOARD. I ALSO SAW SMOKE COMING FROM THE BATTERY COMPARTMENT UNDER THE HOOD. I OPENED THE HOOD AND MORE SMOKE WITH COMING FROM THE VENT. I OPENED THE PASSENGER SIDE DOOR AND SAW THAT BEHIND THE CENTER CONSOLE JUST UNDER THE CD PLAY, THE WIRES WERE ON FIRE AND THE FIRE CONTINUED TO BECOME LARGER. I CALLED THE FIRE DEPARTMENT AT 1:56 PM AND AGAIN AT 1:59 PM WHEN THEY ARRIVED AND THE ENTIRE DASHBOARD WAS BURNING. THE VEHICLE'S DASHBOARD WAS COMPLETELY MELTED ALONG WITH THE...

WHEN WE TURN LEFT, THE VEHICLE TURNS OFF ,LOSES POWER STEERING, BRAKES, GAUGES LIGHT UP, THIS ONLY HAPPENS WHEN TURNING LEFT BETWEEN 3-5 MILES HOUR, THE GARAGE SAID THEY COULD NOT FIND ANYTHING WRONG, AND THE STABILITY CONTROL IS ON TO. *TR

THE "STABILITY CONTROL DISABLED" SENSOR COMES ON FOLLOWED BY "REDUCED ENGINE POWER" AND MY VEHICLE WON'T GO FASTER THAN 5MPH. THIS HAS HAPPENED AT LEAST 6 TIMES IN THE PAST SEVERAL MONTHS ONLY UPON START UP OF THE VEHICLE. SOMETIMES, IF I WAIT A COUPLE OF MINUTES AND RESTART MY CAR, IT'LL START JUST FINE BUT THE CHECK ENGINE LIGHT COMES ON. I FIRST BROUGHT IT INTO HENDRICK CHEVROLET ON 10/15/12. THEY CHARGED ME ALMOST $700 TO REPLACE "APP SENSOR ASSEMBLY". THEN I BROUGHT IT IN AGAIN ON 11/6/12 FOR THE SAME ISSUE. THEY REPLACED THE "CONNECTOR AT THE THROTTLE BODY" AND CHARGED ME $223.09. THE ISSUE TEMPORARILY WENT AWAY. I THEN BROUGHT IT BACK ON 12/20/12 WITH THE SAME ISSUE BUT THIS TIME THE CHECK ENGINE WON'T TURN OFF AS A RESULT OF THE REDUCED ENGINE POWER-STABILITY CONTROL DISABLED WARNING. THEY SIMPLY RESET THE WARNING AND THAT WAS IT....

MY HUSBAND'S 2004 YUKON DENALI CAUGHT FIRE WHILE PARKED IN THE DRIVEWAY OF HOME. THE VEHICLE HAD BEEN SITTING FOR NEARLY TWO HOURS BEFORE IT SPONTANEOUSLY IGNITED. I CALLED 911 WHILE MY HUSBAND TOOK THE HOSE AND SPRAYED WATER ON THE FIRE, WHICH WAS IN THE DASHBOARD OF THE SUV. THE FIRE DEPARTMENT ARRIVED A FEW MINUTES LATER AND PUT THE FIRE OUT. FORTUNATELY, NO ONE WAS INJURED, BUT IT IS UNKNOWN WHY THE VEHICLE IGNITED AND WAS ON FIRE. I CONTACTED GMC VIA ONLINE CHAT, AND THE REPRESENTATIVE SAID THERE ARE NO RECALLS ON THE 2004 YUKON DENALI. AFTER SOME PRELIMINARY SEARCHES ONLINE, I FOUND NUMEROUS CLAIMS OF THE SAME THING OCCURRING TO OTHER OWNERS OF YUKON AND TAHOE SUVS IN THE U.S.. *TR

TL*THE CONTACT OWNS A 2004 GMC YUKON DENALI. THE CONTACT NOTICED THAT THE INSTRUMENT PANEL WAS READING INACCURATELY. HE STATED THAT WHILE DRIVING THE SPEEDOMETER WOULD FLUCTUATE AND HE WAS UNABLE TO DETERMINE HOW FAST OR SLOW HE WAS TRAVELING. THE GASOLINE GAUGE FUNCTIONED INTERMITTENTLY. THE CONTACT WAS CONCERNED THAT BECAUSE OF THE FAILURE; HE COULD POTENTIALLY BE DRIVING ON AN EMPTY FUEL TANK WHICH COULD RESULT IN A CRASH. THE DEALER STATED THAT THEY WOULD ASSUME THE REPAIR COST IF THE VEHICLE HAD 80,000 MILES OR LESS. THE MANUFACTURER ADVISED THE CONTACT THAT THERE WERE NO RELATED RECALLS. THE VEHICLE WAS NOT REPAIRED. THE CURRENT MILEAGE WAS 93,775 AND THE FAILURE MILEAGE WAS UNKNOWN.

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

TL* THE CONTACT OWNS A 2004 GMC YUKON DENALI. THE CONTACT WAS DRIVING 30 MPH WHEN HE NOTICED THAT THE SPEEDOMETER WAS PROVIDING INACCURATE SPEEDS TRAVELED AND READING A MUCH HIGHER SPEED THAN THE CONTACT WAS ACTUALLY DRIVING. THE VEHICLE WAS NOT INSPECTED BY A DEALER OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 124,000.

INSTRUMENT PANEL SOMETIMES WORKS AND SOMETIMES IT DOES NOT. *TR

SPEEDOMETER OPERATES ERRATICALLY IF AT ALL. VEHICLE HAS 100,000 MILES AND GM WILL ONLY REPLACE THE CLUSTER IF UNDER 70,000 MILES. THIS IS A HUGE SAFETY RISK. *TR

FLASHING ABS LIGHT AND THEN ALTERNATING FLASHING TC (TRACTION CONTROL) LIGHT. THEN THE VEHICLE LOCKS UP THE LEFT SIDE FRONT BRAKE AND PULLS THE VEHICLE INTO ON COMING TRAFFIC. HAPPENS INTERMITTENTLY. CAUSE BY THE WHEEL SPEED SENSOR FAILING ON THE VEHICLE. REPLACEMENT OF PART REMOVES ISSUE. *TR

2004 GMC YUKON XL DENALI SYSTEM STABILIZATION DISABLED WARNING LIGHT INTERMITTENTLY COMES ON. THE DEALER CANNOT REPAIR THIS ISSUE BECAUSE THERE ARE NO DIAGNOSTIC CODES IN THE CAR COMPUTER. I HAVE TAKEN THE TRUCK TO THE DEALERSHIP WITH THE WARNING LIGHT ON, BUT STILL NO ERROR CODES. ONSTAR RUNS DIAGNOSTICS AND REPORTS NO ERRORS AND TELLS ME TO DRIVE TO THE NEAREST DEALERSHIP BECAUSE THE VEHICLE IS UNSAFE. THIS FIRST OCCURRED IN DECEMBER WHILE THE TRUCK WAS STILL UNDER WARRANTY, NOW SEVERAL TRIPS TO THE SERVICE SHOP AND IT STILL IS COMING ON. I AM WORKING WITH GMC CUSTOMER SUPPORT TO TRY TO RESOLVE THE ISSUE, BUT TO DATE THEY ARE SAYING THEY CAN'T FIX IT BECAUSE THERE ARE NO DIAGNOSTIC CODES. I HAVE ASKED THEM IF THE TRUCK IS SAFE TO DRIVE WITH WARNING LIGHT ON, BUT THEY CANNOT ASSURE ME THAT IT IS. THEY REFUSE TO DOCUMENT ANYTHING...

WHILE DRIVING AT 50 MPH, SPEEDOMETER 'FAILED' TO THE NEEDLE POINTING STRAIGHT DOWN. I DROVE ANOTHER 10 MINUTES HOME, SPEEDOMETER NEEDLE NEVER MOVED. CYCLING ENGINE OFF/ON SEEMED TO CAUSE THE NEEDLE TO 'DECREASE' INDICATED SPEED BY ABOUT 10 MPH WITH EACH CYCLING. AFTER CYCLING THE IGNITION ABOUT 15 TIMES WHILE PARKED IN MY DRIVEWAY, SPEED AGAIN READ 0. STARTING THE ENGINE AGAIN, THE INDICATOR STILL READ 0, AND WHEN DRIVING AROUND THE BLOCK, THE SPEEDOMETER SEEMED TO WORK AGAIN. DOING A GOOGLE SEARCH FOR POSSIBLE FIXES, I FOUND A WEB-SITE FULL OF PEOPLE WITH SIMILAR ISSUES WITH COMPARABLE GMC VEHICLES. IS THERE A RECALL IN THE WORKS? *NM

ERRATIC SPEED SHOWN ON SPEEDOMETER. SHOWS ZERO AT ONE TIME AND THEN READ MAX OUT AT 120. TOOK IT TO HAVE REPAIRED AND WAS TOLD THAT THEY HAD HAD NUMEROUS OTHERS WITH THE SAME PROBLEM. COST TO REPAIR $600!!! I FOUND A WEBSITE WITH 209 POSTED COMPLAINTS OF THE SAME PROBLEM. THIS IS CLEARLY A SAFETY ISSUE THAT NEEDS ATTENTION. WITH A POSSIBLE INTERACTION WITH THE CRUISE CONTROL NOT TO MENTION INACCURATE SPEED. *NM

FIRST MY OIL GAUGE STARTED GIVING FALSE READINGS ON MY 2004 GMC DENALI, I COULD LIVE WITH THAT. THEN MY SPEEDOMETER READINGS ARE ALL OVER THE PLACE...ALL THE TIME WITH DIFFERENT READINGS. I AM SCARED FOR MY SAFETY AND THE SAFETY OF OTHERS. FROM READING ONLINE THIS IS A VERY COMMON PROBLEM ON GMC VEHICLES AND I FEEL SOMETHING SHOULD BE DONE BY GMC TO REMEDY THE PROBLEM!!! *NM

I HAVE NOTICED SEVERAL TIMES THAT MY SPEEDOMETER WILL STICK OR STOP WORKING ALL TOGETHER. AFTER SEARCHING ON THE INTERNET, I SEE THAT MANY OTHER PEOPLE ARE HAVING THE SAME PROBLEM WITH THEIR CHEVROLET AND GMC TRUCKS AND LIGHT DUTY TRUCKS. *NM

SPEEDOMETER VERY ERRATIC. *NM

DT*: THE CONTACT STATED WHILE DRIVING AT NO CERTAIN SPEED, THE SPEEDOMETER BECOMES INOPERATIVE. FOR EXAMPLE, WHEN DRIVING AT 10MPH, THE SPEEDOMETER READS 110MPH. THE VEHICLE WAS TAKEN TO THE LOCAL DEALERSHIP FOR INSPECTION AND REPAIR OF THE INSTRUMENT PANEL CLUSTER. THE SPEEDOMETER NOW READS CORRECTLY.
