THE GOVERNMENT HAS CAR MAKERS TRYING TO GAIN MORE FUEL ECONOMY BY HAVING THEM MAKE THEIR VEHICLES SMALLER AND LIGHTER, BUT THAT IS FOR CARS ALMOST ONLY. SO NOW THAT TRUCK REMAIN STANDARD AS BEFORE THEIR HEAD LIGHTS ON DIM ARE HIGHER THEN THE REAR VIEW MIRROR IN THE CARS THEREFORE CAUSING BLINDNESS TO THE CAR DRIVER. THE GOV. SHOULD SET A MAX. HEIGHT FOR HEADLIGHTS TO BE OFF THE ROAD WHEN THE VEHICLE IS SITTING ON A LEVEL SURFACE. AND THEN THE LAW ALLOWS SOME OF THESE TRUCK OWNERS TO JACK THEIR UNIT UP EVEN HIGHER THAN STANDARD TO WHERE THE HEADLIGHTS OR EVEN ABOVE THE ROOF OF THE CARS AND IT VERY DANGEROUS AT NIGHT WHEN YOU MEET ONE COMING OR ONE PULLS UP BEHIND YOU. OF COURSE I KNOW THERE WILL BE NOTHING DONE ON SOMETIME LIKE THIS UNTIL 100 PEOPLE HAVE WRECKS AND OR KILLED OR THEY RUN OVER SOMEONE FOR NOT BEING ABLE TO SEE THEM IN THE BLINDING LIGHTS OF A STANDARD HIGH RISE TRUCK. RIGHT? *TR

TL*THE CONTACT OWNS A 2000 CHEVROLET SILVERADO 1500. EVER SINCE THE VEHICLE WAS PURCHASED, THE ENGINE HAS BEEN MAKING A STRANGE NOISE. THE CONTACT TOOK THE VEHICLE TO THE DEALER AND THEY FOUND NO FAILURES. THE MANUFACTURER STATED THAT THEY WERE AWARE OF THE PISTONS STRIKING AGAINST THE METAL BECAUSE THERE WAS NOT ENOUGH CLEARANCE BETWEEN THE PISTONS AND THE CYLINDER. THE MANUFACTURER COULD NOT CORRECT THE FAILURE AND THERE WERE NO RECALLS FOR THE ISSUE. THE MILEAGE ON THE VEHICLE HAS EXCEEDED THE WARRANTY; THEREFORE, THE MANUFACTURER WILL NOT ASSIST. IN ADDITION, THE CONTACT HEARD A NOISE COMING FROM THE REAR OF THE VEHICLE. THE DEALER STATED THAT THERE WAS A SLACK IN THE REAR, WHICH COULD BE REPAIRED BY REPLACING THE YOKE WITH A NICKEL PLATED COVER. THE REPAIR WAS NOT PERFORMED BECAUSE THE CONTACT FEELS AS IF THE MANUFACTURER SHOULD BE RESPONSIBLE FOR THE REPAIR COST. THE FAILURE MILEAGE WAS 87,000 AND CURRENT MILEAGE WAS 125,350. UPDATED 06/09/09. *LJ THE CONSUMER STATED WHEN THE TRANSMISSION SHIFTED INTO 2ND AND SOMETIME THIRD GEAR, THE REAR END OF THE VEHICLE SOUNDED AS IF IT WERE ABOUT TO COME APART. THE ENGINE ALSO MADE A NOISE AS IF THE VALVES WERE CLICKING AND TAPPING. UPDATED 06/10/09.*JB

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.
