FUEL/PROPULSION SYSTEM
WHILE TRAVELING AT APPROX. 20-25MPH, PULLING AWAY FROM MY HOME, A SMALL ANIMAL RAN ACROSS IN FRONT OF ME. I HIT THE BRAKES, HARD, AND AFTER A MOMENTARY FEELING OF BRAKE PRESSURE, THE PEDAL WENT STRAIGHT TO THE FLOOR WITH NO BRAKES WHATSOEVER. I BACKED UP INTO MY DRIVEWAY, JACKED UP THE TRUCK AND PLACED IT ON JACK STANDS. THE UNDERSIDE OF THE TRUCK WAS WET AND DRIPPING BRAKE FLUID AROUND THE ABS UNIT BENEATH THE CAB. MY WIFE APPLIED THE BRAKE WHILE I EXAMINED THE UNDERSIDE. AN APPROX. 1/8IN HOLE WAS FOUND IN THE INCREDIBLY RUSTY AND WEAK STEEL LINE RUNNING FROM THE ABS TO THE LEFT FRONT WHERE IT JOINS THE RUBBER LINE TO THE L/F CALIPER. FURTHER EXAMINATION REVEALS ALL STEEL BRAKE LINES ARE INCREDIBLY RUSTY, STRUCTURALLY WEAK AND IN DANGER OF FAILURE. THIS COULD LEAD TO A VERY SERIOUS, CATASTROPHIC CRASH WITH THE POTENTIAL OF FATALITIES. FURTHER, ALL OF THE STEEL PARTS OF THE FUEL LINES ARE ALSO VERY, VERY RUSTY AND WEAK AND WITH THE HIGH INTERNAL PRESSURES AND HIGHLY FLAMMABLE AND EXPLOSIVE GASOLINE INSIDE ARE ANOTHER SERIOUS HAZARD. I AM A LICENSED MASTER AUTO/TRUCK AND MOTORCYCLE MECHANIC. IN NEARLY 50 YEARS OF DRIVING I HAVE NEVER SEEN A BRAKE LINE FAILURE FROM SUCH MASSIVE RUST ON A VEHICLE WITH SUCH LOW MILEAGE. THIS VEHICLE HAS ONLY 68,830 MILES ON IT. IT IS UNSAFE TO DRIVE. MANY, MANY OTHER OWNERS OF SIMILAR GMC AND CHEVROLET TRUCKS HAVE REPORTED SIMILAR BRAKE LINE RUST AND FAILURE. REPAIR/REPLACEMENT COST ESTIMATES CAN BE AS HIGH AS $1200 TO NEARLY $2000. BRAKE LINE FAILURE CAN KILL. IF EVER THERE WAS JUSTIFICATION FOR A SAFETY RELATED RECALL, THIS IS CERTAINLY IT. *TR

MY DRIVER'S DOOR LOCK ACTUATOR HAS BEGUN WORKING INTERMITTENTLY. THIS IS THE SECOND DOOR LOCK ACTUATOR ON MY VEHICLE TO FAIL, THE FIRST WAS REPLACED UNDER WARRANTY AND THE GM MECHANIC TOLD ME THEY HAVE REPLACED NUMEROUS ACTUATORS. THE VEHICLE AUTOMATICALLY LOCKS ALL DOORS WHEN DRIVEN AND UNLOCKS WHEN STOPPED HOWEVER THE FAULTY ACTUATOR DOES NOT ALWAYS LOCK OR UNLOCK. THESE ACTUATORS HAVE A LONG HISTORY OF BEING DEFECTIVE AND GM IS AWARE OF IT BUT REFUSES TO RECALL THE FAULTY ACTUATOR EVEN THOUGH THEY HAVE LITERALLY REPLACED THOUSANDS OF THESE UNITS. THESE FAULTY ACTUATORS ARE A SAFETY CONCERN BECAUSE IN THE EVENT OF AN ACCIDENT A DOOR COULD FAIL TO UNLOCK EFFECTIVELY TRAPPING THE OCCUPANTS. THE FAULTY ACTUATORS ARE ALSO A SECURITY CONCERN BECAUSE THEY COULD FAIL TO SECURE THE VEHICLE ALLOWING ANYONE ACCESS TO IT'S CONTENTS. *TR
