AS I WAS DRIVING AT 75 MPH, THE INDICATOR LIGHT SAID, ENGINE OVERHEATED. I THEN NOTICED WHITE SMOKE COMING FROM THE HOOD. THE WHITE SMOKE TURNED BLACK. I PULLED OVER TO THE SIDE OF THE ROAD AND BEFORE I COULD SHUT THE ENGINE OFF, THE ENGINE SHUT OFF ON ITS OWN. FIRE BEGAN COMING UP WHERE THE WINDSHIELD WIPERS ARE LOCATED AND PROCEEDED THROUGH THE DASHBOARD. I TRIED TO UNLATCH MY SEAT BELT BUT IT WOULD NOT RELEASE. AFTER SEVERAL TRIES IT RELEASED. I ATTEMPTED TO OPEN THE DOOR; HOWEVER, I HAD THE SAME PROBLEM. THE DOOR DID NOT OPEN. AFTER BUMPING THE DOOR FORCIBLY MANY TIMES, IT ALSO CAME OPEN. MIND YOU, ALL THE WHILE THE FLAMES ARE COMING INSIDE THE CAB. I CALLED 911 AND THE COUNTY FIRE DEPARTMENT WAS DISPATCHED, BUT NOT BEFORE IT WAS FULLY ENGULFED IN FLAMES. THE VEHICLE WAS WELL MAINTAINED. I WANT TO KNOW WHAT STEPS TO TAKE TO PREVENT THIS FROM EVER HAPPENING AGAIN?

I OWN A 2002 CHEVROLET SILVERADO LS HD2500, ORIGINAL OWNER PURCHASED IN JUNE OF 2002, CURRENTLY HAVE 71,000 MILE, BEAUTIFUL TRUCK VERY WELL MAINTAINED. THIS IS MY SECOND COMPLAINT BEING FILED ON THIS VEHICLE CONCERNING MY BRAKES. MY FIRST COMPLAINT WAS FILED IN MARCH OF 2014, WHEN MY BRAKE LINES RUSTED THROUGH AND I WAS LEFT WITH NO BRAKES. AFTER SEARCHING ON-LINE, I FOUND THAT THIS IS A KNOWN PROBLEM FOR THESE VEHICLES AND THERE IS A RECALL ON SOME OF THESE VEHICLES, BUT NOT ALL OF THEM. MY COMPLAINT TODAY ALSO HAS TO DO WITH MY BRAKES. ONCE AGAIN, I FOUND THAT SOME OF THE VEHICLES HAVE A RECALL, BUT NOT ALL OF THEM . THE ANTI-LOCK BRAKE SYSTEM WOULD ACTIVATE, CAUSING MY BRAKES TO NOT WORK. IF I WANTED TO STOP, I COULDN'T SLOW DOWN TO STOP, I WOULD HAVE TO BRAKE HARD TO STOP MY VEHICLE, IF I TRIED TO SLOW DOWN TO STOP, MY ANTI-LOCK BRAKE SYSTEM WOULD ACTIVATE, CAUSING MY BRAKES TO NOT WORK. I DID CONTACT GM, AND WAS TOLD THAT THERE WAS NOTHING THEY COULD DO TO HELP RESOLVE THIS PROBLEM WITH MY VEHICLE BECAUSE MINE WAS NOT INCLUDED IN THE RECALL, EVEN THOUGH SOME OF MY YEAR, MAKE AND MODEL HAD A RECALL NOTICE. THEY ARE WELL AWARE OF THIS PROBLEM, BECAUSE THEY DO HAVE A BULLETIN OUT INFORMING THE DEALER HOW TO RESOLVE THIS PROBLEM. ONCE AGAIN, THIS IS THE BRAKE SYSTEM, VERY DANGEROUS, COULD BE FATAL. NOT SURE WHY THIS ISN'T A PRIORITY TO RESOLVE.

RUSTED OUT BRAKE LINE TO REAR BRAKES ALONG FRAME RAIL ON MY 2002 SILVERADO 4 X 4. THANK GOD NO ONE WAS INJURED. THIS TRUCK I PURCHASED BRAND NEW AND HAS NEVER SEEN ANY WINTER WEATHER UNTIL 2013. I WAS INVOLVED IN A UNRELATED ACCIDENT IN JAN. 2013 AND THE TRUCK SAT AT A BODY SHOP UNTIL THE END OF MAY 2013. THIS YEAR I HAD TO USE MY TRUCK. SHOULD A BRAKE LINE HAVE RUSTED THRU PREMATURELY? I DON'T THINK SO. I THINK GM SHOULD BE ACCOUNTABLE FOR THIS FAILURE AND REIMBURSE ALL PEOPLE AFFECTED BY THIS SUBSTANDARD PART FAILURE. *TR
