WHILE DRIVING FROM CHICAGO TO MILWAUKEE ON 1/26/11 MY SPEEDOMETER STARTED TO INDICATE VERY ABNORMAL SPEEDS. MY PORTABLE GPS INDICATED I WAS TRAVELING 62 MPH YET MY YUKON'S SPEEDOMETER READ 110 MPH. WHEN I REACHED MY DESTINATION IN MILWAUKEE AND TURNED MY YUKON OFF, THE SPEEDOMETER REMAINED AT 55 MPH. I IMMEDIATELY GOOGLED FAULTY YUKON SPEEDOMETERS AND FOUND A LARGE QUANTITY OF SITES CONTAINING DEFECT INFORMATION ABOUT GMC YUKON'S SPEEDOMETERS. I ALSO READ THAT GM SUPPOSEDLY SENT OUT LETTERS TO CUSTOMERS. I CAN ASSURE YOU THAT I NEVER RECEIVED A LETTER ABOUT THIS. HAVING 3 SMALL CHILDREN I WOULD NOT LET SOMETHING AS SERIOUS AS THIS GO UNFIXED HAD I BEEN MADE AWARE. I AM NOW AT 96,000 MILES AND SEE THAT GM'S "RECALL" ENDS AT 80,000 MILES. IT WOULD HAVE BEEN NICE TO HAVE BEEN NOTIFIED SO I COULD HAVE HAD THIS REPAIRED. THIS IS EXACTLY ONE OF THE MANY REASONS PEOPLE HAVE LOST FAITH IN GM AND OTHER AMERICAN CAR MANUFACTURERS. *TR

2005 FAULTY GMC YUKON DASH SYSTEM. DEALER ORIGINALLY TOLD ME IT WAS THE FUEL PUMP BUT SUGGESTED IT MIGHT BE ALCOHOL IN THE GASOLINE. I TRIED USING ETHANOL FREE GAS AND IT WORKED. I COULDN'T FIND ANY ETHANOL FREE GAS ON DEC 25TH SO I HAD TO USE 10% ETHANOL AND MY ENTIRE DASH HAS QUIT WORKING. I CAN'T TELL HOW FAST I'M GOING, IF I HAVE FUEL OR HOW MANY MILES I HAVE ON MY VEHICLE. THE GMC DEALERSHIP WANTS ME TO REPLACE MY FUEL PUMP, DASH BOARD AND THEY ESTIMATE IT WILL COST AROUND $1500. IT WORKED FINE WITHOUT ETHANOL! *TR

FAULTY SPEEDOMETER 2005 GMC YUKON. I RECENTLY SAW A NEWS REPORT ON FAULTY SPEEDOMETERS WITH GM VEHICLES DONE BACK IN 2007 AND I AM EXPERIENCING THE SAME PROBLEM WITH MY 2005 GMC YUKON. CURRENTLY MY SPEEDOMETER SITS AT 60 MPH IN PARK AND GETS PINNED AT 120 MPH ON THE ROAD WHEN I'M ONLY MOVING AROUND 40 MPH. I HAVE CONTACTED GMC AND THEY TOLD ME THE WARRANTY ON THIS PROBLEM IS 5 YRS OR 70,000 MILES. ONE PROBLEM, I AM AT 91,000 MILES AND THEY TOLD ME GMC MAILED OUT LETTERS STATING THE SPEEDOMETER PROBLEMS. I NEVER RECEIVED THIS LETTER!! NOW THEY ARE OFFERING TO FIX THE PROBLEM FOR $600!! I HAVE ALSO CONTACTED GM CUSTOMER HELP LINE AND THE SAID THE SAME THING. MY QUESTION IS IF GMC ADMITS TO THE FAULTY SPEEDOMETER THEN WHY DID THEY PUT A 70,000 MILE CAP ON THE WARRANTY FOR THIS ISSUE WHICH IS CLEARLY A SAFETY HAZARD?? COULD YOU PLEASE HELP? ALSO DO YOU HAVE ANY ADVICE WITH THIS ISSUE? THANK YOU FOR YOUR HELP AND FOR LOOKING OUT FOR THE CONSUMER. *TR

DRIVING VEHICLE AT HIGHWAY SPEEDS FOR APPROX. 1 HOUR CAUSES DIAL-TYPE SPEEDOMETER TO BEGIN REGISTERING INCORRECTLY. INITIALLY THE DEVIATION IS ONLY 3-4 MPH, BUT OVER TIME WILL WORSEN. ACTUAL SPEED IS BEING MEASURED WITH HANDHELD GPS UNIT TO CHECK AGAINST SPEEDOMETER DEVIATION. SPEEDOMETER CAN REGISTER OVER OR UNDER ACTUAL SPEED. AT WORSE, SPEEDOMETER CAN SHOW 0-5 MPH WHILE TRAVELING AT 60-65 MPH ACTUAL, AND AT OTHER TIMES HAS REGISTERED 110-115 MPH WHILE TRAVELING AT 40-45 MPH ACTUAL. IF ENGINE IS SHUT OFF AND RESTARTED, SPEEDOMETER WILL REGISTER ACTUAL SPEED FOR A SHORT TIME, THEN BEGIN DEVIATING FROM ACTUAL AGAIN. PROBLEM DOES NOT APPEAR TO OCCUR WHEN ONLY TRAVELING AT SPEEDS BELOW HIGHWAY SPEED (30-45 MPH), BUT WHEN TRAVELING AT HIGHWAY SPEEDS LONG ENOUGH FOR DEVIATION TO OCCUR, SPEEDOMETER WILL BEGIN REGISTERING OVER/UNDER ACTUAL AT ANY ACTUAL SPEED IF VEHICLE IS BEING CONTINUOUSLY DRIVEN (NOT SHUT OFF). *TR

MY 2005 YUKON 4WD WENT OUT. IT STARTED AS AN INTERMITTENT PROBLEM. THE FIRST TIME I TOOK IT TO THE DEALER SINCE IT WAS NOT CURRENTLY HAVING PROBLEMS THEY WERE UNABLE TO IDENTIFY THE ISSUE. THIS TIME IT WAS OUT FOR SEVERAL DAYS BEFORE I FINALLY TOOK IT IN. ALTHOUGH NOTHING EXTREME HAPPENED, SINCE I WAS AWARE OF THE ISSUE, BUT IF SOMEONE WAS NOT AWARE OF THE ISSUE THEY COULD POTENTIALLY LOSE CONTROL OF THERE VEHICLE SINCE THE TRACTION CONTROL SYSTEM IS ALSO DISABLED IN THIS PROBLEM. REPLACED THE 4WD ACTUATOR TOTAL BILL 762.00 WAS ALSO TOLD IT COULD POTENTIALLY SHORT OUT THE BRAIN BOX FOR THE 4WD OPERATING SYSTEM. THE FIRST TIME IT HAPPENED IT WAS WHEN THE WEATHER WAS COLD, NEVER HAD AN ISSUE ALL SUMMER UNTIL NOW, WHEN THE WEATHER TURNED COLD. MY VEHICLE ONLY HAD 38,000 MILES THE FIRST TIME AND 52,000 THIS TIME. MY 1999 YUKON HAD 158,000 AND I NEVER HAD AN ISSUE WITH IT. *TR
