“THE PASS LOCK KEEPS MY VEHICLE FROM STARTING AND STOPPING IT AT RANDOM, AND HAS BEEN DOING THIS FOR YEARS. SEEMS TO HAPPEN TO AT LEAST 85% OF HUMMERS OUT THERE IF YOU CHECK AROUND, HUMMER FORUM AND OTHER PLACES. THIS IS VERY SERIOUS. STOPS AT INTERSECTIONS, AND COULD ON RAILROAD TRACKS. I KNOW THAT YOU'VE HAD COMPLAINTS ABOUT THIS FOR YEARS AND IGNORED THEM, SAYING THAT YOU HAVEN'T HAD OTHER COMPLAINTS. THIS SHOULD BE ADDRESSED BY YOUR AGENCY, AS YOUR JOB IS TO KEEP THE CITIZENS SAFE. NOT PASS THEM OFF AS YOU'VE BEEN DOING FOR YEARS ON THIS ISSUE WITH THE GM PASS LOCK SYSTEM. THIS NEEDS RECALLED BEFORE MORE PEOPLE ARE KILLED DUE TO THIS MISS FUNCTION ON HUMMERS. MORE PEOPLE ARE HAVING THIS SHUTDOWN ISSUE THAN NOT. WHEN IT HAPPENS, YOU HAVE TO WAIT BETWEEN 10 AND 30 MINUTES WITH THE KEY IN THE START POSITION BEFORE IT WILL START. SO IT SITS IN THE MIDDLE OF AN INTERSECTION, INTERSTATE, BRIDGE, OR ANYWHERE ELSE DURING THIS TIME. HOPEFULLY YOU WILL ADDRESS THIS ISSUE PROMPTLY.”
“I WENT TO CRANK UP MY HUMMER TO WARM IT UP DUE TO THE VERY COLD WEATHER ONCE I CRANKED THE HUMMER I IMMEDIATELY SMELLED A VERY STRONG BURNING ODOR. IT BEGIN TO SMOKE AND MY HUSBAND YELLED IT YOUR TRUCK AND I LOOKED AND SAW THE SMOKE GETTING WORSE AND THICKER. I UNHOOKED MY INFANT SON'S CAR SEAT BELT AND TOOK HIM OUT OF THE VEHICLE. I RAN TO THE BUILDING WE WERE LEAVING TO CALL 911 BECAUSE OF THE SMOKE WHILE ON THE PHONE WITH THE 911 DISPATCHER I SAW THE FIRE START INSIDE THE TRUCK ON THE STEERING WHEEL AND DASHBOARD IT THEN IT IMMEDIATELY SPREAD AND BURNED THE ENTIRE INSIDE OF THE TRUCK WHERE IT IS NOT RECOGNIZABLE. THE FIRE DEPARTMENT CAME AND SPRAYED WATER ON IT TO PUT OUT THE FIRE THERE WERE BLUE AND RED SPARKS SHOOTING OUT OF THE TRUCK. THE SPARKS AND FIRE STARTED IN THE STEERING WHEEL AREA WHICH SHOWED THERE WAS AN ELECTRICAL ISSUE THAT CAUSED THIS FIRE. I CHECKED OTHER RECALLS AND NOTICED THAT THE ISSUE I SPEAK OF WAS RECALLED INSIDE OF THE 2006 H2 HUMMERS. *TR”
