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.

Mileage: 32,000

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.

Mileage: 130,000

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 THAT LUXURY, I LOST MY JOB, WE ARE PAY CHECK TO PAY CHECK WITH MY HUSBANDS INCOME. I CAN'T FIX OR REPLACE THIS CAR, THAT I ABSOLUTELY LOVED BEFORE ALL THE MALFUNCTIONS/DEFECTS. I HAVE A GARMIN SO I CAN TELL MY SPEED, AND HAVE TO HIT THE SIDE INSIDE THE CAR WHEN THE LIGHTS WON'T WORK. I PRAY, YOU WILL LOOK INTO THIS MATTER BEFORE SOMEONE IS SERIOUSLY HURT, AS SO MANY HAVE REPORTED THE SAME COMPLAINTS. ONE GENTLEMEN GAVE YOU A WEBSITE I'VE SEEN MYSELF OF PEOPLES COMPLAINTS. I THANK YOU FOR YOUR TIME, AND ANYTHING YOU CAN DO TO HELP US!! *TR

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

Mileage: 82,000

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 CONTROLS ABOVE BY THE SUNROOF. THE VEHICLE IS A COMPLETE LOSS. THE VEHICLE HAS BEEN PARKED AT MY JOB FOR MORE THAN 6 HOURS BEFORE I TOOK IT TO GO HOME. I SUSTAINED SMOKE INHALATION AND HEAT BURNS ON MY FACE. I WAS TRANSPORTED TO THE LOCAL HOSPITAL, TREATED AND RELEASE. *TR

Mileage: 136,000

I HAVE A 2004 GMC YUKON DENALI AND AS I SEE FROM THE MANY COMPLAINTS BEFORE ME MY CLUSTER HAS WENT OUT. I HAVE NO USE OF MY DASHBOARD AT ALL. NO USE OF GAS GAUGE. NO USE OF SPEEDOMETER. NO USE OF OIL GAUGE. NO USE OF ANYTHING ON DASH. WHY AFTER ALL THE COMPLAINTS HAS GMC NOT DONE ANYTHING. IF THIS CAUSES AN ACCIDENT LIKE WHAT IS GOING ON NOW WITH IGNITION SWITCH THEY WILL PAY SO MUCH MORE WITH LAWSUITS. I WILL BE THE FIRST IN LINE, CAN'T TELL YOU HOW MANY TIMES I HAVE RAN OFF THE ROAD FOR LACK OF GAS

I STARTED MY CAR AND WHILE I WAS IN PARK THE SPEEDOMETER SAID 70MPH. WHILE I WAS DRIVING IT WOULD REGISTER OVER 120MPH. I HAD NO IDEA WHAT SPEED I WAS TRULY GOING. THIS IS A SCARY FEELING ESPECIALLY WITH MY THREE CHILDREN IN THE CAR. I TRIED TURNING OFF THE CAR PUTTING IT IN DRIVE AND BACK TO PARK THINKING PERHAPS IT WAS STUCK, BUT NOTHING WORKS. I SEE THIS IS A COMMON PROBLEM...HELP?? *TR

Mileage: 164,020

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

Mileage: 118,000

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. TIL THIS DAY, I CONTINUE TO HAVE PROBLEM WITH THIS VEHICLE GOING INTO REDUCED ENGINE POWER/STABILITY CONTROL DISABLED. THIS HAS BECOME A CONSTANT ISSUE AND THORN ON MY SIDE AND EACH TIME I BRING IT IN FOR SERVICE, THEY ALWAYS TELL ME IT'S SOMETHING ELSE. I HAVE READ MANY OF THE SAME ISSUES OTHER OWNERS HAVE HAD. WHY HAVEN'T THERE BEEN A RECALL ON THIS??? *TR

Mileage: 137,509

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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

WHEN DRIVING THE SPEEDOMETER WOULD GET STUCK. THEN GO BACK TO NORMAL. THIS HAPPENED FOR ABOUT TWO MONTHS THEN IT ALL STOPPED WORKING ALL THE GAUGES ARE NOW NOT WORKING. *TR

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.

Mileage: 124,000

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

Mileage: 52,000

TL*THE CONTACT OWNS A 2004 GMC YUKON DENALI. WHILE DRIVING AT AN UNKNOWN SPEED, THE CONTACT OBSERVED THAT THE SPEEDOMETER DISPLAYED AN INACCURATE READING. THE FAILURE NORMALLY WOULD OCCUR ONLY DURING THE COLD WINTER TEMPERATURES; HOWEVER, THE FAILURE BECAME PROGRESSIVELY WORSE INTERMITTENTLY DURING HOT TEMPERATURES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED WHEN THE COMPLAINT WAS FILED. THE FAILURE MILEAGE WAS 90,000. THE VIN WAS NOT AVAILABLE.

Mileage: 90,000

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

MY SPEEDOMETER FAILED ON MY 2004 GMC YUKON DENALI. THERE IS A RECALL ON THE INSTRUMENT CLUSTER FOR THIS FOR MODEL YEAR 2003-2006, BUT ONLY UP TO 80,000. I HAD 104,000 WHEN THE INCIDENT HAPPENED ON MY VEHICLE. IT COST ME $600 TO GET THIS DIAGNOSED AND REPLACED. I CONSIDER THIS A SAFETY ISSUE AND IT SHOULD NOT HAVE A LIMIT ON MILEAGE. NOT KNOWING HOW FAST YOU ARE GOING CAN CAUSE PROBLEMS ON AN INTERSTATE HIGHWAY. BY DRIVING TO SLOW, ONE CAN CAUSE OTHER DRIVERS TO ERRATICALLY PASS AND ZOOM BY YOU OR DRIVING TO FAST CAN CAUSE OTHER DRIVERS TO HURRIEDLY GET OUT OF YOUR WAY AND CAUSE ACCIDENTS. THIS IS MORE THAN LIKELY THE CAUSE OF A SPEEDING TICKET I GOT BACK IN MAY 2009. IT POSSIBLY WAS ACTING UP, BUT DIDN'T COMPLETELY FAIL UNTIL JULY 2009. *TR

Mileage: 104,000

SPEEDOMETER CLUSTER FAILED. GM IS COVERING THE MALFUNCTION UP TO 70,000 MILES. I HAVE 80,000...IT SEEMS THAT THIS IS A VERY COMMON MALFUNCTION. GM WON'T COVER OVER 70,000 MILES. ITS A SAFETY ISSUE IF YOUR SPEEDOMETER QUITS WORKING. *TR

Mileage: 81,000

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

Mileage: 82,000

IN THE INSTRUMENT CLUSTER ON MY 2004 GMC YUKON, THE SPEEDOMETER HANGS UP INDICATING A HIGHER SPEED THAN ACTUALLY TRAVELING. INITIALLY, THE PROBLEM OCCURRED AT INTERVALS GREATER THAN 6 MONTHS BUT SEEMS TO BE RECURRING MUCH MORE FREQUENTLY - EVERY 2 WEEKS OR SO. UPON INITIAL PROBLEM BEING NOTICED, I FOUND THAT OTHER MODEL YEAR YUKONS HAD THIS ISSUE AND WERE REPAIRED, POSSIBLY UNDER RECALL BUT MY MODEL YEAR WAS EXCLUDED. *TR

Mileage: 60,000

THE SPEEDOMETER IS NOT FUNCTIONING CORRECTLY, ESPECIALLY IN COLD WEATHER. THE SPEEDO SEEMS TO STICK AND READS INCORRECTLY. IT HAPPENS DAILY AND HAS NOT BEEN FIXED. *TR

WE PURCHASED OUR GMC DENALI USED IN JULY 2007. IN JUNE OF THIS YEAR I NOTICED SOMETIMES THAT WHEN I WOULD LOOK AT THE SPEEDOMETER IT WOULD SAY THAT I WAS DOING ABOUT 40 MPH, WHEN I KNEW THAT I WAS NOT GOING THAT SPEED. I WAS KEEPING UP WITH TRAFFIC WHEN I FIRST NOTICED IT AND THE SPEED LIMIT WAS 55MPH. ABOUT A MONTH LATER I NOTICED THAT THE SPEED ODOMETER WOULD SAY I WAS NOT MOVING AT ALL THAT MY SPEED WAS 0, AND I WOULD BE DRIVING AT THE TIME. THEN IN JULY OF THIS YEAR WE WERE COMING BACK FROM A FAMILY DAY TRIP AND WE WERE PULLED OVER FOR SPEEDING. THE OFFICER INFORMED US THAT WE WERE GOING ABOUT 55 WHEN THE SPEED LIMIT WAS 40. ACCORDING TO THE SPEED ODOMETER WE WERE GOING THE SPEED LIMIT. NOW WHEN I DRIVE THE VEHICLE I AM EITHER GO NO SPEED AT ALL OR THE SPEED ODOMETER STARTS GOING CRAZY OR GETS STUCK AT 40MPH. I HAVE NOT BEEN ABLE TO FINE ANY RECALL ON THIS MATTER. *TR

SPEEDOMETER HAS INTERMITTEN FAILURE. IT REGISTERS INCORRECT SPEEDS (OFTEN SHOWING 80 MOH WHEN PARKED) OR DOES NOT WORK AT ALL. *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 IN WRITING ABOUT THE SAFETY OF THE TRUCK. TO DATE THERE HAVE BEEN NO ACCIDENTS NOR INJURIES, BUT I HAVE LOST ALL CONFIDENCE IN THE VEHICLE AS I WAS TOLD THE STABILIZATION SYSTEM WAS MANDATED BY THE GOVERNMENT AND IT MUST BE OPERATIONAL. WHAT RECOURSE DO I HAVE TO INSURE THE TRUCK IS SAFE? WHY CAN'T THEY REPLACE COMPUTER MODULES UNTIL THERE IS A RESOLUTION? THE TRUCK DID NOT DO THIS FOR THE FIRST 35 MONTHS I OWNED IT, DRIVING THE SAME EXACT ROADS THAT THE WARNING FLASHES ON NOW. *TR

FOR THE PAST 2 WEEKS MY SPEEDOMETER NEEDLE HAS BEEN GETTING STUCK. ONCE I HIT 60MPH, IT GETS STUCK THERE. WHEN I TURN OFF THE CAR IT STAYS AT 60 SO IT ACTS AS IF IT'S AT 0MPH. AT THAT POINT IT LOOKS LIKE I'M GOING 100MPH WHEN IN REALITY I'M GOING 40MPH UNTIL IT GETS STUCK PAST 120MPH. AFTER A FEW DAYS IT STARTS SLOWLY DROPPING. IT'S AMAZING THAT THIS PROBLEM HAS NOT BEEN TAKEN CARE OF AFTER MANY MANY COMPLAINTS FROM OWNERS. I WILL MAKE SURE TO GIVE NEGATIVE REPORTS TO ANYONE LOOKING TO BUY A GM VEHICLE AS WELL AS TO POTENTIAL USED GM OWNERS. *TR

ON THE DATE LISTED BELOW, MY SPEEDOMETER BEGAN TO REGISTER INCORRECT SPEEDS. IT THEN BECAME STUCK ON 70 MPH WHEN MY VEHICLE WAS STOPPED. IT HAS NOT STOPPED WORKING ALL THE WAY AND IS STUCK AT 140MPH. WHILE AT MY LOCAL DEALERSHIP GETTING MY OIL CHANGED, I ASKED AN ATTENDANT IF HE WAS GETTING MANY SPEEDOMETER REPAIRS FOR MY MAKE/MODEL. HE STATED THAT HE HAS REPLACED MANY AND THAT THE PROBLEM IS A FAULTY "STEP MOTOR"?? I ASKED THE SERVICE MANAGER IF THERE WERE ANY RECALLS AND HE STATED "HE WAS NOT FAMILIAR WITH ANY PROBLEMS." HE STATED HE WOULD FIX MY SPEEDOMETER FOR APPROXIMATELY $400. THE SERVICE TECH STATED THE MOTOR COSTS $10. I HAVE READ A FEW THREADS ON THE TOPIC AND THERE SEEMS TO BE A SERIOUS PROBLEM, AND NOT THE PROPER RESPONSE FROM THE MAKER. BASICALLY A DEFECTIVE PART AND A CAR COMPANY MAKING LOTS OF MONEY TO REPAIR IT. VEHICLE I OWN IS A 2004 YUKON DENALI. *TR

MY 2004 GMC DENALI HAS SOME SERIOUS PROBLEMS WITH THE SPEEDOMETER AND GAS GAGE NOT SHOWING CORRECT READINGS. SPEEDOMETER SHOWS 50,60,70 WHEN YOU ARE ONLY GOING 30. SOMETIMES ON THE HIGHWAY I AM PASSING EVERYONE AND HAVE NO CLUE AS TO HOW FAST I AM GOING. I CAN BE GOING PRETTY FAST JUST SETTING STOPPED AT A STOP LIGHT SOMETIMES. AND I HAVE NO CLUE AS TO HOW MUCH GAS I HAVE ANYMORE. THEY SENT OUT A LETTER THAT STATED THAT THEY WOULD FIX THIS AND EXTENDED THE WARRANTY FOR 7 YEARS OR 70,000 MILES WHICHEVER COMES FIRST. WELL MY VEHICLE HAS 108000 MILES ON IT, BECAUSE I BOUGHT IT TO TRAVEL IN AND WE DRIVE IT. THEY DON'T CONSIDER THIS A SAFETY ISSUE, SO NO RECALL. SINCE WHEN DOES DRIVING 90 MILES AN HOUR WHEN YOU THINK YOU ARE GOING 70 NOT A SAFETY ISSUE? OR PERHAPS RUNNING OUT OF GAS IN THE MIDDLE OF NOWHERE AND FREEZING TO DEATH. *TR

2004 YUKON DENALI SPEEDOMETER MALFUNCTIONED CAUSING WRONG SPEED READINGS. *TR

Mileage: 55,000

WHILE DRIVING HOME THE SPEEDOMETER STOPPED READING ANY SPEED. IT SLOWLY DRIFTED DOWN TO 0 MPH. WHILE DRIVING I ACCELERATED THINKING THAT I WAS LOOSING SPEED ONLY TO FINALLY REALIZE THAT THE SPEEDOMETER WAS MALFUNCTIONING. THE CAR HAS 70,000 MILES ON THE ODOMETER WHICH I AM ASSUMING IS ACCURATE. THIS IS A VERY DANGEROUS ITEM TO HAVE FAIL. THIS COULD EASILY CAUSED AN ACCIDENT WHEN APPROACHING A CURVE THE DRIVER WOULD THINK THAT THE CAR IS TRAVELING SLOWER THAN IT ACTUAL. MAKES AN OMINOUS CLICKING NOISE. THIS AM ON THE WAY TO WORK APPEARED TO BE FUNCTIONING NORMALLY!!! VERY STRANGE AND DEFINITELY NOT "PROFESSIONAL GRADE". *JB

Mileage: 70,000

PURCHASED CAR MAY 24, 2007 WITH 68004 MILES. ON MAY 25TH SPEEDOMETER STARTED STICKING AND THEN STOPPED WORKING ALTOGETHER. THEN WORKING SPORADICALLY. WAS CLOCKING 0MPH ON HIGHWAY WHEN ESTIMATED SPEED PROBABLY 60MPH. HAVE NOT DONE ANYTHING TO REPAIR YET. SEEMS LIKE A DEFECT AS PER HUNDREDS AND HUNDREDS OF COMPLAINTS ON LINE.

SPEEDOMETER STARTED READING 120 MPH SITTING STILL RIGHT AFTER CAR WAS OUT OF WARRANTY I AM NOT ALONE WITH THIS PROBLEM THERE ARE TENS OF THOUSANDS JUST LIKE MINE WITH NO GM RECALL THIS ITEM NEEDS TO BE RECALLED IT IS DANGEROUS DRIVING WITH NO ACCURATE SPEEDOMETER. *JB

STANDING STILL THE SPEEDOMETER READS 30+ MPH, START MOVING & THEY ARE READING WELL OVER 120 MPH. I NO LONGER HAVE ANY IDEA HOW FAST I AM TRAVELING IN EITHER OF MY VEHICLES. THIS IS UNSAFE & GM SHOULD IMMEDIATELY RECALL ALL AFFECTED VEHICLES & FIX THIS PROBLEM QUICKLY. I HAVE 8 CHILDREN & WOULD LIKE TO KNOW THAT I AM DRIVING AT A SAFE SPEED AT ALL TIMES. *NM

SPEEDOMETER STICKING AND REPORTING INCORRECT VEHICLE SPEED. SPEEDOMETER WOULD CONSISTENTLY DROP OVER THE COURSE OF THE TRIP AND FINALLY IT WILL REPORT 0 MPH WHILE THE CAR IS IN MOTION ON AN INTERSTATE. TEMPORARY FIX IS TO PULL OVER AND TURN THE CAR COMPLETELY OFF AND TRY AGAIN. IT WORKS FOR AROUND 60 MILES AND PROBLEM STARTS ALL OVER AGAIN. DEALER SUGGESTED TO REPLACE INSTRUMENT CLUSTER WHICH WILL COST ANY FROM $250-350. THIS IS A COMMON ISSUE PER MY RESEARCH ONLINE. THERE ARE MANY EBAY VENDORS THAT SPECIALIZE IN THIS AND CHARGE GOOD MONEY. *JB

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

Mileage: 55,000

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.
