NHTSA Complaint #11089772 — 2005 CHEVROLET SILVERADO 2500

DRIVER SIDE SEAT HEATER TURNS ON BY ITSELF. THIS IS A DANGEROUS SITUATION BECAUSE THE DRIVER IS DISTRACTED WHILE DRIVING AND MUST LOOK DOWN TO FIND THE OFF SWITCH. OFTEN, THE SEAT HEAT COMES BACK ON AGAIN ALMOST RIGHT AWAY.. THIS SITUATION SEEMED TO OCCUR IN APPROX 2003 TO 2007 MODELS. INTERNET FORUMS SHOW THAT GM HAS SERVICE BULLETINS THAT INSTRUCT TECHNICIANS TO DO A 'FIRMWARE FIX". THE ONLY WAY FOR ME TO STOP THIS CONDITION WAS TO LOCATE AND DISCONNECT A SMALL GREEN CONNECTOR UNDER THE SEAT THAT DISABLES THE SEAT HEATER. CHANGING THE CONTROL MODULE DIDN'T REMEDY THE SITUATION. IT HAPPENS WHILE DRIVING AND IS INTERMITTENT. SEEMS LIKE GM HAS REMEDIED THE SITUATION IN NEWER MODELS. SEEMS TO ME THEY SHOULD BE RECALLING OLDER MODELS TO INCORPORATE SOME SORT OF "FIX". THE DISTRACTION OF LOCATING AND TURNING OFF THE HEATER IS AS BAD AS "DRIVING WHILE TEXTING". I ALWAYS HAVE TO PULL OVER TO GET IT SHUT OFF. OFTEN, WHEN I RESUME DRIVING, THE HEATER WILL COME BACK ON. EVENTUALLY IT STOPS TURNING ITSELF ON.
