“I OWN A 2004 CHEVY IMPALA 3.8L WITH APPROX 179,000 MILEW.MY COMPLAINT IS IN RELATION TO THE PASSLOCK III SYSTEM AND THE OVERWHELMING AMOUNT OF "NO START" COMPLAINTS FROM ALL THE DIFFERENT MODELS OF GM CAR OWNERS ACROSS THE BOARD WITH THIS FAULTY ANTI-THEFT SYSTEM. I LIVE RIGHT SMACK IN THE HEART OF THE SOUTH IN A VERY SMALL TOWN IN TENNESSEE AND KEEP IN MIND, IT IS REALLY HOT AND HUMIDITY IS RIDICULOUS THIS TIME OF YEAR. I PICKED UP MY DAUGHTER AT A FRIENDS HOUSE AFTER WORK, ABOUT 5:25 PM LAST THURDAY, 9/5/19, AND MY CAR DIED AS I'M DRIVING DOWN THE ROAD, LIKE THE ENGINE JUS SHUT OFF FOR NO REASON AT ALL , I HAD FILLED MY TANK A FEW DAYS PRIOR AND KNEW THAT WAS NOT THE PROBLEM. MY FIRST THOUGHT WAS TO PUT IN NEUTRAL BEFORE LOSING MUCH SPEED AND TRIED TO CRANK SEVERAL TIMES BEFORE HITTING MY FLASHERS BECAUSE THERE WERE A FEW CARS BEHIND ME ON A 2 LANE ROAD WITH VERY LITTLE SHOULDER ROOM TO PULL OVER OFF ROAD. I POPPED THE GOOD TO SEE IF I COULD SEE OR MAYBE EVEN SMELL ANYTHING THAT MAY HAVE CAUSED THIS PROBLEM. I'M MAKING SURE MY BATTERY CABLES AREN'T LOOSE, NO FLUIDS LEAKING OR SPEWING AND LUCKILY A STATE TROOPER WAS PASSING THRU AND STOPPED TO SEE IF I NEEDED…”
