My husband just had a wreck last night. His gas pedals got stuck causing him to lose control of the truck and the truck to spend around in the middle of the street. It hit another car and a telephone pole before jumping the curb and landing in a field. THE AIR BAGS DID NOT DEPLOY ON ANY PARTS OF THE TRUCK THAT WAS IMPACTED BY THE WRECK. Both sides of the truck are completely smashed in and both windshields have been busted out. My husband actually came of the windshield of the truck where the Airbag should have deployed.

CRACKED FRAME BETWEEN SPRING HANGERS: THE FRAMERAILS BROKE VERTICALLY FROM BOTTOM FLANGE TO DIAGONAL SLOT AT OR NEAR NEUTRAL AXIS OF BOTH FRAME RAILS. THE FRAME RAIL HAS LARGE HOLE IN BOTTOM OF RAIL HORIZONTAL FLANGE OF 'C' SHAPE FOR ACCESSING BED/BOX MOUNTING BOLTS. CRACK PROPAGATES FROM THIS HOLE TO DIAGONAL HOLE IN THE VERTICAL WEB OF 'C' SHAPE RAIL. OVERLOADING SHOULD CAUSE THE FRAME TO FAIL FROM TOP DOWN NOT BOTTOM UP. DUE TO THE VERY THIN OEM MATERIAL AND TORSION OR TWIST INDUCED INTO THE FRAME BY LARGE OFFSET FROM THE SHEAR CENTER OF THE 'C' SHAPE TO LOADING CENTER OF THE REAR MOST SPRING HANGER. THIS PICKUP HAS NOT BEEN ALTERED IN ANY MANNER. SEVERAL COMPLAINTS HAVE BEEN POSTED ON THE INTERNET, WITH THIS SAME PROBLEM. GRANTED SOME OF THESE ARE DUE TO OPERATING THE VEHICLE OUTSIDE DESIGN PARAMETERS AND ALTERATIONS SUCH AS LIFT KITS AND LARGE TIRES. HOWEVER THE DESIGN APPEARS NOT TO EVEN MEET MANUFACTURER'S STATED HAULING AND TOWING CAPABILITIES, WHICH THE AFTERMARKET CHANGES ONLY EXACERBATES. THE CRACK ON MY VEHICLE WILL ONLY PROPAGATE FURTHER ON MY VEHICLE SHOULD I CONTINUE TO USE IT WITHIN GM'S RATINGS. THIS AN ISSUE COULD BE LIFE THREATING AS NEAR TO TOTAL CRACKING COULD CAUSE LOSE OF VEHICLE CONTROL. HIGHWAY RUTTING WHILE PULLING A TRAILER CAUSES SOME WHIP AND THIS WHIP WILL WORSEN AS THE CRACK PROPAGATES UPWARD.

I OWN A 2000 CHEVY SILVERADO TRUCK AND HAD NOT HAD ANY PROBLEM(S) WITH DOORS UNTIL ON AUGUST 18, 2016 THE POWER LOCK MECHANISM FOR THE PASSENGER DOOR STOPPED WORKING. THE DRIVERS SIDE DOOR STILL WORKED. I FELT THAT MY KEY TO THE DOORS WOULD ALLOW ACCESS TO THE PASSENGER SIDE BUT IT WOULD NOT OPEN. THE KEY DID WORK ON THE DRIVERS SIDE. THE SLIDE BAR ON THE PASSENGER SIDE DOOR ALSO COULD NOT MOVE THUS RENDERING THAT DOOR IN A CONSTANT STATE OF BEING LOCKED. I BECAME VERY CONCERNED THAT A VEHICLE COULD BE MADE WITH POWER LOCKS AND NOT HAVE SOME SYSTEM TO MANUALLY ALLOW THE OPENING OF THE VEHICLE. IF THE VEHICLE WERE IN AN ACCIDENT AND THE ONLY WAY OUT WAS THE PASSENGER DOOR THE OCCUPANT COULD FACE SERIOUS INJURY OR EVEN DEATH. THIS SEEMS TO BE A SEVERE SAFETY RISK. NOW I'M AFRAID TO DRIVE TRUCK FOR FEAR THIS MIGHT HAPPEN ON DRIVER'S SIDE AND I WOULD BE UNABLE TO GET OUT OF TRUCK.

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
