2005 GMC YUKON XL Electrical System Problems

THIS VEHICLE HAS BEEN IN AND OUT OF THE SHOP SEVERAL TIMES FOR THE SAME REASON, "REDUCED ENGINE POWER". IT PUTS ME IN A DANGEROUS POSITION SOMETIMES BECAUSE THE VEHICLE WILL SUDDENLY GO INTO THIS "LIMP MODE" I HAVE SPENT SEVERAL THOUSAND DOLLARS IN REPAIRS AND FIXES BY QUALIFIED MECHANICS AND YET THIS PROBLEM WILL NOT GO AWAY. AFTER MUCH RESEARCH I FIND THAT I AMONG MANY PEOPLE WITH THE SAME PROBLEM. IT HAPPENED THREE TIMES YESTERDAY!

2005 GMC YUKON. CONSUMER WRITES IN REGARDS TO VARIOUS ELECTRONIC PROBLEMS INCLUDING SERVICE AIR BAG INDICATOR. *SMD THE CONSUMER STATED HE EXPERIENCED CHRONIC PROBLEMS WITH SPEEDOMETER, STARTING PROBLEMS, WHEEL HUB AND TRACTION CONTROL SENSOR. ALSO, THE TRANSFER CASE WAS REPLACED. *JB

MY 2005 GMC YUKON XL 1500 WILL SPONTANEOUSLY SHIFT ITSELF INTO 4LO. THIS DOESN'T ONLY HAPPEN AT LOW SPEEDS. IT OCCURS AT ALL SPEEDS WHEN THE VEHICLE IS MOVING AND IN GEAR. WHEN IT HAPPENS, ALL OF THE LIGHTS ON THE PUSH-BUTTON 4WD CONTROL MODULE WILL LIGHT UP OR FLASH. NO AMOUNT OF BUTTON-PUSHING WILL DISENGAGE 4 WHEEL DRIVE. I HAVE ALSO NOT COME ACROSS ANY SORT OF MANUAL FIX, I.E. TURNING OFF THE IGNITION, TAKING THE VEHICLE OUT OF GEAR, BACKING UP, ETC. THIS HAS HAPPENED MORE THAN 5 TIMES, AND HAS ONLY CEASED TO HAPPEN BECAUSE I HAVE REMOVED THE RELAY WHICH CONTROLS THE 4WD SYSTEM. I AM FIRMLY CONVINCED THAT IT IS ONLY THROUGH SHEER BLIND LUCK OR DIVINE INTERVENTION THAT NO ONE HAS BEEN INJURED WHILE OPERATING THIS VEHICLE. LET ME RESTATE: THIS ISSUE OCCURS ENTIRELY AT RANDOM, AND NOT ONLY WHEN JUST STARTING OFF DRIVING....

THE SPEEDOMETER STICKS .....THE PROBLEM IS A FAULTY STEPPER MOTOR WHICH ESSENTIALLY CONTROLS THE MOVEMENT OF THE SPEEDOMETER NEEDLE. APROX $600.00 TO REPAIR INSTRUMENT CLUSTER. *TR

TL*THE CONTACT OWNS A 2005 GMC YUKON XL. WHILE DRIVING APPROXIMATELY 70 MPH HE NOTICED THAT MOST OF THE GAUGES ON THE INSTRUMENT CLUSTER WERE NO LONGER WORKING. HE STATED THAT THE TEMPERATURE GAUGE WAS WORKING. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO PERFORMED A DIAGNOSTIC TEST AND STATED THAT THE INSTRUMENT CLUSTER WAS DEFECTIVE. THE VEHICLE HAD NOT BEEN REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGES WERE 60,000.

INSTRUMENT PANEL CLUSTER GAUGE NEEDLE -- SPEEDOMETER GAUGE -- WORKS INTERMITTENTLY. IT STICKS ON 0MPH, ON A PREVIOUS RATE OF SPEED REGARDLESS OF INCREASE OR DECREASE, OR DISPLAYS RATE OF SPEED AT 100+ MPH. VERY INCONSISTENT. WHEN THE SPEEDOMETER DOES DECIDE TO WORK IT IS ABOUT 10-15 MPH OFF OF ACCURATE RATE OF SPEED. (COMPARED TO GPS THAT DISPLAYS CURRENT RATE OF SPEED) IT WAS TAKEN TO DEALER AND CONTACT STATED THAT IT IS SAME CLUSTER PANEL GAUGE OF 2003-04 YEAR MODELS CURRENTLY IN RECALL ALTHOUGH HAS NOT EXTENDED TO 2005-06 YEAR MODELS AT THIS TIME. *TR
