IN THE MIDST OF TRAVELING ON VACATION, THE SPEEDOMETER AND MANY OF THE OTHER DASH COMPONENTS JUST QUIT WORKING. I HAD TO RELY SOLELY ON THE PORTABLE GPS TO DETERMINE THE SPEED THAT I WAS GOING. THIS IS UNSAFE, AND THIS IS AN ISSUE THAT HUMMER MOST CERTAINLY NEEDS TO CORRECT.

STARTING IN OCTOBER 2013 MY SPEEDOMETER HAS NOT FUNCTIONED PROPERLY. IT DOES NOT DISPLAY THE CORRECT SPEED NO MATTER HOW FAST OR SLOW YOU ARE GOING. IT IS EITHER STUCK AT 0 OR BOTTOMS OUT OVER 120. I HAVE NO IDEA HOW FAST I AM DRIVING UNLESS I USE MY PORTABLE GPS THAT SHOWS SPEED. IF IT WASN'T FOR MY GPS THEN I COULD GET INTO AN ACCIDENT OR GET A TICKET BECAUSE I WOULD NOT KNOW HOW FAST I AM GOING. THIS IS A MANUFACTURE DEFECT AS I AM NOT THE ONLY HUMMER OWNER WITH THIS ISSUE. GM NEEDS TO FIX THIS PROBLEM ASAP. *TR

DRIVING HOME I BEGAN TO SMELL AND ELECTRICAL BURNING SMELL. IT BEGAN VERY QUICKLY AND CAME AND WENT FOR ABOUT 2 MILES. I PULLED OVER AND LOOKED AND COULD NOT SEE SMOKE OR FIRE SO I CONTINUED HOME. I DROVE THE REMAINING 4 MILES TO MY HOME AND IMMEDIATELY GOT MY HUSBAND TO CHECK AS THE CAB HAD FILLED WITH THE SMELL OF AN ELECTRICAL FIRE. HE LOCATED THE AREA THE SMELL WAS STRONGEST AND THEN WATCHED AS SMOKE CAME OUT. HE UNBOLTED THE WINDSHIELD WASHER FLUID TANK AND THE MOTOR ON BOTTOM HAD ACTUALLY BURNED, MELTED AND WAS ON THE VERGE OF CAUSING SOME SERIOUS DAMAGE. THE WIPERS WERE NOT BEING USED AND HAD NOT BEEN TOUCHED. THIS VEHICLE IS EQUIPPED WITH A HEATER FOR THE FLUID. *TR

THE SPEEDOMETER AND TACHOMETER IN MY VEHICLE GET STUCK AT ANY SPEED. BOTH METERS EITHER MAX OUT OR DROP TO ZERO AT NUMEROUS SPEEDS. AT SLOW SPEEDS THIS PROBLEMS IS NOT A MAJOR ISSUE, BUT AT SPEEDS ABOVE 45 MPH THE PROBLEM CREATES A DANGEROUS SITUATION. WHEN PULLING A TRAILER ON THE INTERSTATE AT 70 MPH THE SPEEDOMETER HAS DROPPED TO ZERO. THIS CREATES A DANGEROUS SITUATION AN INABILITY TO DETERMINE REQUIRED SPEEDS ON DIFFERENT SECTIONS OF THE HIGHWAY. A PROBLEM SUCH AS THIS ONE SHOULD ONLY OCCUR IN A VEHICLE 25 OR 30 YEARS OLD AND NOT 6 YRS OLD. IT'S CLEAR THAT THIS IS A FACTORY DEFECT AND AN ALERT SHOULD BE ISSUED FOR FACTORY REPAIR OF THIS DEFECT. THANK YOU *TR

I STARTED MY VEHICLE 4 DAYS AGO AND THE SPEEDOMETER AND GAUGES WERE FROZEN AND DID NOT OPERATE AT ALL. I DROVE TO THE STORE AND THE GAUGE REMAINED AT 0 THE ENTIRE TIME. WHEN YOU ACCELERATE THE SPEEDOMETER DOES NOT MOVE FROM 0 MPH. I TURNED THE VEHICLE OFF AND TURNED IT BACK ON AND THERE WAS NO CHANGE. YESTERDAY WHEN I STARTED THE VEHICLE THE GAUGE WOULD ONLY MOVE BETWEEN 30-50 MPH. TODAY WHEN I STARTED THE VEHICLE IT IS FROZEN AT 120 MPH AND THE KHM(?) DOES NOT MOVE PAST 1.WHEN I ACCELERATE NEITHER OF THE TWO GAUGES ARE FUNCTIONING. I HAVE YET TO REPAIR IT BC IT HAS HAPPENED JUST A FEW DAYS AGO BUT I WAS TOLD THAT I AM LOOKING AT A VERY LARGE REPAIR COST TO REPLACE THE ENTIRE DASHBOARD CLUSTER. THE SAME THING HAPPENED IN MY 2003 MODEL AND I SOLD THE VEHICLE. AS WELL THE REAR SUSPENSION IS LOWERING ON ITS OWN TO THE LOWEST POSITION AND DOES NOT GO BACK TO THE NORMAL HEIGHT. I HAVE TO PUSH THE BUTTON ON THE INTERIOR. WHEN I RETURN TO THE VEHICLE THE FOLLOWING MORNING THE REAR SUSPENSION HAS DROPPED DOWN AGAIN. *TR
