TL* THE CONTACT OWNS A 2005 GMC YUKON. WHILE DRIVING AT APPROXIMATELY 55 MPH, THE CONTACT NOTICED SMOKE COMING FROM THE AIR CONDITIONER VENTS. IN ADDITION, THE CABLE UNDER THE DASHBOARD ON THE PASSENGER SIDE CAUGHT FIRE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 100,000.

I HAVE NOTICED OVER THE PAST YEAR THAT THE SHIFT INDICATOR IN THE INSTRUMENT CLUSTER HAS BEEN INTERMITTENT/NOT VISIBLE DURING ANY OPERATION OF CAR OPERATION. THIS HAS BEEN A COMPLAINT TO THE LOCAL DEALER DO TO A SAFETY ISSUE IN WHICH YOU DO NOT SEE WHAT POSITION THE SHIFT INDICATOR IS IN.

TL* THE CONTACT OWNS A 2005 GMC YUKON. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT REMAINED ILLUMINATED. THE ONSTAR DIAGNOSTIC CHECK DETERMINED THAT THE IGNITION SWITCH NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 122,000.

MY SPEEDOMETER QUIT WORKING AND I CHECKED AND IT IS A FACTORY DEFECT. *TR

INTERIOR VEHICLE FIRE IN DASH. 1ST SMOKE THEN CENTER OF DASH ERUPTED INTO FLAMES. VEHICLE IS NOW TOTALLED. GMC IS AWARE OF THIS CONDITION AND ISSUED NO RECALLS. APPEARS SERVICE BULLETINS WERE ISSUED ABOUT REPLACING OVER HEATING RESISTORS FOR THE (HAVC) OPERATING SYSTEM. THE FAN WOULD EITHER STOP WORKING IN A FEW POSITIONS /STOP WORKING ALL TOGETHER OR OVERHEAT AND SET FIRE. *TR

TL* THE CONTACT OWNS A 2005 GMC YUKON. THE CONTACT STATED THAT THE SPEEDOMETER REMAINED STUCK ON 120 MPH AND WOULD NOT PROVIDE AN ACCURATE READING OF SPEEDS TRAVELED. THE VEHICLE WAS NOT TAKEN TO THE DEALER AND WAS NOT REPAIRED. THE CONTACT STATED THAT THERE WAS A MANUFACTURER RECALL FOR HIS YEAR, MAKE AND MODEL VEHICLE BUT HIS VIN WAS NOT INCLUDED IN THE RECALL. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 65,000.

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

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

SPEEDOMETER ACTING ERRATIC. AT HIGHWAY SPEED SOMETIMES READS 25MPH. JERKY REACTION AT ALL SPEEDS. OIL PRESSURE GAUGE STUCK ON 80 PSI. *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

THE SPEEDOMETER WENT FROM 70MPH TO 120MPH AND THEN JUST STUCK THERE- OUR SPEED WAS APPROXIMATELY 70MPH AT THE TIME THE SPEEDOMETER FAILED. *TR

SPEEDOMETER BEGAN TO ACT ERRATIC, THEN COMPLETELY FAILED AT 60 MPH...EVEN WHEN STOPPED. THE SPEEDOMETER IS NOT LONGER RESPONSIVE AND UNRELIABLE FOR SAFE TRAVEL. GM OWES THE PUBLIC A RECALL NOTICE, BEFORE SOMEONE IS KILLED! A NEW INSTRUMENT CLUSTER IS REQUIRED TO FIX THIS PROBLEM, A 500 DOLLAR FIX. *TR

I WAS ALSO TOLD THAT THESE THEY HAVE SEEN A LOT OF THESE VEHICLES WITH THE SAME PROBLEM. SUPPOSEDLY, THERE WAS A RECALL FOR 2003 AND 2005 MODELS HAVING PROBLEMS WITH THEIR SPEEDOMETER. *TR
