NHTSA Complaint #11005043 — 2008 GMC SIERRA 1500

DRIVING AND WARNING CAME ON AND IT SAID "ENGINE HOT A/C TURNED OFF" HAD THIS VEHICLE ONLY ONE WEEK WHEN THIS HAPPENED, TOWED BACK TO THE DEALER THE SAID WASN'T UNDER WARRANTY, I TOLD THEM TO KEEP THE TRUCK. THEY PUT ON A NEW THERMOSTAT, TWO WEEKS LATER SAME THING. TOOK TRUCK TO MY MECHANIC AND HE REPLACED THE THERMOSTAT. GOOD FOR ABOUT TWO MONTHS, WARNING KEEPS COMING ON. LOOKED ON LINE MANY PEOPLE HAVE HAD THIS HAPPEN, A MECHANIC AT A CHEVROLET GARAGE TOLD ME IT IS PROBABLY IN THE CLUSTER PANEL/ COMPUTER?? BIG MONEY. WITH ALL THE PROBLEMS OTHER'S HAVE BEEN HAVING, I THINK IT IS DANGEROUS TRUCK CATCH ON FIRE GOING DOWN THE ROAD. WOULD LIKE AN ANSWER TO THIS PROBLEM. THANK YOU MARY ANN
