ON JUNE 4, 2014, DRIVING ON A CLEAR, DRY AND SUNNY DAY IN MY 2003 GMC SIERRA DENALI PICKUP TRUCK. ON VIRGINIA DRIVE HEADING EASTBOUND IN MONTGOMERY COUNTY, PA, AT 32 MPH; WITH NORMAL BRAKING ACTION HEADING INTO A CURVE, THE BRAKE PEDAL SURPRISINGLY WENT TO THE FLOOR AND EXPERIENCED LOSS OF BRAKING. FORTUNATELY I WAS ABLE TO NEGOTIATE THE TURN, NARROWLY ESCAPING RUNNING OFF THE ROAD, ONLY BECAUSE IT WAS TWO LANE ROAD IN EACH DIRECTION AND THERE WAS NO NEARBY TRAFFIC AT THE TIME. BRAKE FUNCTIONALITY NEVER RETURNED EXCEPT FOR MINIMAL CAPABILITY NEAR THE END OF PEDAL TRAVEL. PRELIMINARY INSPECTION AFTER PARKING THE VEHICLE INDICATES THE BRAKE LINES SHOWED RUSTING IN GENERAL ON THE VEHICLE (AND ALSO THE ADJACENT FUEL LINES), MOSTLY NEAR THE FRONT SECTION OF THE VEHICLE; AND THE FAILURE SEEMED TO BE IN THE HOSE-TO-LINE COUPLING FROM THE BRAKE VALVE NEAR THE MASTER CYLINDER TO WHAT APPEARS TO BE THE ABS CONTROL ASSEMBLY MOUNTED ON THE FRAME UNDER THE DRIVER'S SEAT AREA. THE LINES IN THAT SUSPECTED FAILURE AREA APPEARED MOST SERIOUSLY RUSTED AND BULGED. CURRENTLY SPEAKING WITH A GMC DEALER TO UNDERSTAND THE REPAIR OPTIONS AND POSSIBLE RECALLS. *TR

AFTER JUST A FEW YEARS OF OWNERSHIP, MY 2003 DENALI, WHICH I PURCHASED BRAND NEW, STARTED TO HAVE "POWER DOWN" ISSUES. WHILE DRIVING, THE VEHICLE WOULD JUST LOOSE POWER AND I WOULD HAVE TO PULL OVER AND RESTART THE VEHICLE. GMC HAS ALWAYS ACTED AS IF IT WAS NOT A BIG DEAL AND HAVE OFFERED MANY EXPENSIVE SOLUTIONS. EARLY ON I TRIED THEIR RECOMMENDATIONS AND IT WOULD HELP FOR A WHILE BUT THE PROBLEM ALWAYS COMES BACK. FURTHER, ALL OF MY GAUGES HAVE QUIT WORKING. AGAIN, GM OFFERS VERY EXPENSIVE SOLUTIONS, BUT WILL NEVER OWN UP TO THE FACT THAT THESE VEHICLES ARE DEFECTIVE. AFTER GOING THROUGH THIS FOR SEVERAL YEARS, I GOOGLED THESE ISSUES AND DISCOVERED THAT THERE ARE PAGES AND PAGES OF COMPLAINTS ABOUT THE SAME ISSUES. I LOVE MY VEHICLE AND NOW HAVE 230,000 MILES ON IT. HOWEVER, I KNOW THAT THIS IS VERY DANGEROUS AND I AM ALWAYS CONSCIOUS THAT IT CAN HAPPEN AT ANY TIME. I AM ALWAYS PREPARED TO PULL OVER BUT THERE HAVE BEEN TIMES WHEN I WAS NEARLY REAR-ENDED BECAUSE OF THIS ISSUE. ALSO, I RARELY LET ANY OTHER FAMILY MEMBER DRIVE THE VEHICLE AND WHEN I DO I WARN THEM OF THE ISSUE SO THAT THEY ARE PREPARED. THIS ISSUE IS FIRST AND FOREMOST VERY DANGEROUS AND SECONDLY A TRUE HASSLE AND INCONVENIENCE. MY CHECK ENGINE LIGHT COMES ON EVERY TIME THE VEHICLE POWERS DOWN. THIS HAS CAUSED ME TO HAVE TROUBLE PASSING EMISSIONS AS WELL. I HAVE WANTED TO TRADE OR SELL THE VEHICLE BUT I AM CONCERNED ABOUT MY LIABILITY KNOWING ABOUT THIS ISSUE. *TR

I AM FILING A COMPLAINT DUE TO A REDUCED ENGINE PROBLEM AND STABILITY CONTROL WHICH KEEPS ENABLING ME TO DRIVE THE VEHICLE. ONCE THIS LIGHT AND POWER REDUCES I NEED TO PULL OVER FROM MY DESTINATION AND TURN ENGINE OFF COMPLETELY. I COUNT ABOUT TEN SECONDS IN ORDER TO RESTART THE VEHICLE... ONLY TO START IT AND HAVING IT REDUCE AGAIN. SEVERAL LIGHTS ON DASH BOARD REMAIN ON SUCH AS ENGINE. I HAVE TRIED FIXING THE PROBLEM BUT I GUESS NO ONE REALLY KNOWS HOW TO REPAIR AND THIS HAS BEEN COSTLY. I HAVE READ RESOURCES/CONSUMERS WITH THE SAME YEAR AND VEHICLE MAKE, AND HAVE FOUND THAT THEY HAVE OCCURRED THE SAME PROBLEM. I WOULD LIKE TO KNOW IF THIS HAS BEEN A RECALL ON THE GMC CO. AND OR WHAT THE PROBLEM IS. I FEEL THIS IS A SAFETY ISSUE AND APPARENTLY IT DOES HAVE TO DO WITH GMC THE MANUFACTURE AND WOULD LIKE TO RESOLVE THIS PROBLEM. *TR

WITHIN ABOUT 10 MILES OF A MODERATE BRAKING SITUATION AND REACHING HOME, BRAKE PEDAL BECAME PROGRESSIVELY SOFTER AT EACH SUCCESSIVE STOP UNTIL COMPLETE BRAKE FAILURE OCCURRED NEAR HOME. THE EMERGENCY BRAKE WAS USED TO SLOW AND STOP VEHICLE IN DRIVEWAY (HOME). RIGHT FRONT STEEL BRAKE LINE WAS FOUND TO HAVE BURST DUE TO EXTENSIVE RUST/CORROSION. EXTENSIVE CORROSION OF MOST BRAKE LINES WAS FOUND AND REPAIRED AT CONSIDERABLE COST AS A PREVENTIVE MEASURE TO HELP AVOID ACCIDENT OR INJURY. THE LOCAL GMC DEALER WAS NOT AWARE OF A RELATED RECALL FOR THIS VEHICLE AND WOULD ONLY REPAIR THE SUV AT THE PREVAILING RATE SINCE A WARRANTY WAS NOT IN EFFECT. THIS VEHICLE SHOULD BE RECALLED AND REPAIRED BY THE MANUFACTURER TO ADDRESS THIS POTENTIALLY CATASTROPHIC DEFECT. *JS

I HAVE A 2003 YUKON DENALI AND WHEN IT HIT THE 65,000 MILES MARK THE FUEL GAUGE STOPPED WORKING LEAVING ME TO TELL HOW MUCH GAS I HAD LEFT USING THE AUTOMATIC COMPUTER TELLING YOU HOW MANY MILES TO EMPTY. NEXT THE OIL GAUGES STOPPED WORKING. FINALLY REACHING 80,000 MILES MY SPEED ODOMETER QUITE WORKING LEAVING ME TO NOT KNOWING THE SPEED I AM TRAVELING THIS QUITE WORKING WHILE I WAS DRIVING DOWN A HIGHWAY. TO MAKE MATTERS WORSE MY RPMS ARE STARTING TO GO GOOFY WHICH MEANS THAT TO IS GOING TO STOP WORKING AS WELL. I WAS TOLD THAT HAVING MY DASH TAKEN OFF AND FIXED COULD RUN ANYWHERE BETWEEN 1,000.00 NOT INCLUDING LABOR FEES. WHICH IS CRAZY THAT GMC DOESN'T STAND BEHIND ITS WORK. PEOPLE CANT AFFORD TO BE PAYING FOR THIS TO GET FIXED LET ALONE SPEEDING TICKETS. I BELIEVE SOMETHING NEEDS TO BE DONE AFTER READING ABOUT SO MANY PEOPLE HAVE THIS SAME PROBLEM WITH THE ALL HAVING THE SAME YEAR YUKON DENALI.. YOU PAY ALL THIS MONEY FOR A VEHICLE AND SOMETHING LIKE THIS HAPPENS!!! *TR

TL* THE CONTACT OWNS A 2003 GMC DENALI. THE CONTACT WAS DRIVING APPROXIMATELY 40 MPH WHEN THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT STATED THAT AFTER A FEW MINUTES, THE VEHICLE WAS RESTARTED YET THE FAILURE PERSISTED. THE VEHICLE WAS TOWED TO THE DEALER WHERE THE TECHNICIAN COULD NOT DIAGNOSE THE FAILURE. THE FAILURE PERSISTED INTERMITTENTLY BUT RECURRED MOST DURING WARMER TEMPERATURES. THE VEHICLE WAS TAKEN TO TWO DIFFERENT DEALERS AND AN INDEPENDENT MECHANIC. THE THROTTLE BODY, WIRING HARNESS AND SENSORS WERE REPLACED. THE TIRES WERE ROTATED AND THE PRESSURE WAS CHECKED BUT TO NO AVAIL. THE THROTTLE BODY WAS REPLACED A SECOND TIME BUT STILL THERE WAS NO RESOLUTION TO THE FAILURE. WHEN PERFORMING A DIAGNOSTIC ON THE VEHICLE, THE SAME EXACT FAILURE CODES WERE ALWAYS GENERATED ADVISING OF A THROTTLE BODY FAILURE. THE VEHICLE WAS NOT FURTHER REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 130,000. UPDATED 5/2/11 *CN UPDATED 1/11/11 *CN
