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. IT OCCURS AT SPEED! WHEN THIS HAPPENS, THE VEHICLE LITERALLY CAN GO FROM TRAVELING AT 35 MPH TO LESS THAN 5 MPH. KEEP IN MIND THAT SINCE THE BRAKE IS NOT DEPRESSED, FOLLOWING DRIVERS HAVE NO WARNING OF THIS RAPID DECLINE IN SPEED. I BELIEVE THAT THIS IS A FUNDAMENTAL DEFECT IN GM VEHICLES USING THIS 4 WHEEL DRIVE SYSTEM. I THINK THAT THE ONLY REASON THE PROBLEM IS NOT SEEN AS MORE WIDESPREAD IS THAT THE ISSUE HAPPENS IN DIFFERENTLY-NAMED MAKES AND MODELS. FOR INSTANCE, MY PROBLEM MAY NOT BE READILY CONNECTED WITH THE SAME ISSUE IN A CHEVROLET SUBURBAN, ALTHOUGH THE TWO ARE ESSENTIALLY THE SAME VEHICLE. FURTHER, I BELIEVE THAT GM IS AWARE THAT THIS SAFETY HAZARD IS THE RESULT OF A MANUFACTURING DEFECT AND IS UNWILLING TO TAKE RESPONSIBILITY FOR THE PROBLEM. A SIMPLE INTERNET SEARCH OF "STUCK IN 4LO" WITHOUT IDENTIFYING A MANUFACTURER, BRINGS UP ALMOST EXCLUSIVELY GM-BUILT FULLSIZE TRUCKS USING THE SAME PUSH-BUTTON SYSTEM. I DON'T BELIEVE THAT THIS IS MERE COINCIDENCE. HERE IS AN OPPORTUNITY FOR [XXX] TO SHOW THAT GM OWNS UP TO ITS ERRORS.

WENT ON A VACATION THIS PAST SUMMER TO IDAHO AND NOTICED THAT THE SPEEDOMETER QUITE WORKING. IT WOULD BE 60 MPH WHILE SITTING STILL AND OVER 120 WHEN MOVING. OF COURSE WE WERE PULLED OVER FOR GOING OVER THE SPEED LIMIT. BY THE END OF THE DAY, THE FUEL GAUGE AND TEMPERATURE GAUGE ALSO WENT. NOW ALL THE GAUGES ARE NOT WORKING. TOOK IT A GM DEALER AND HAD TO PAY CLOSE $690 TO HAVE REPAIRED. AFTER READING ONLINE THIS SOUNDS LIKE IT HAS BEEN QUITE AN ISSUE WITH SEVERAL GM VEHICLES. I BELIEVE THAT THIS SHOULD BE A RECALL. *TR

VEHICLE'S INSTRUMENT PANEL FAILS TO OPERATE PROPERLY. VEHICLE IS OUT OF WARRANTY COVERAGE. SPEEDOMETER REGISTERS ~40 MPH WHEN VEHICLE IS STANDING STILL. OIL PRESSURE GAUGE 'PEGS OUT'. GAS GAUGE IS UNRELIABLE. VEHICLE IS 2005 YEAR, GMC HAS RECALLED INSTRUMENT PANELS ON 2003 AND 2004 MODEL YEARS, BUT NOT 2005. WITH UNRELIABLE INSTRUMENT PANEL, THIS IS A SAFETY HAZARD. MADE A VISIT TO DEALER. DIAGNOSED AS NEEDING NEW INSTRUMENT PANEL AT COST EXCEEDING $600. WE FEEL THAT GMC SHOULD CONSIDER EXTENDING RECALL TO ENCOMPASS 2005 MODELS AS WELL. *TR

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
