VEHICLE DESCRIPTION: EXTENDED-CAB PICKUP TRUCKS EQUIPPED WITH HIGH-BACK BUCKET SEATS. THE SEAT RECLINER TO FRAME ATTACHING BOLTS CAN LOOSEN, FATIGUE, AND FRACTURE ALLOWING THE SEAT BACK TO SUDDENLY RECLINE.
THE FOUR U-BOLTS NUTS ON EITHER SIDE OF THE REAR AXLE WERE UNDER-TORQUED.
THESE VEHICLES WERE ASSEMBLED WITH THE THROTTLE CABLE CONTACTING THE DASH MAT WHICH COULD BIND THE THROTTLE. THIS DOES NOT MEET WITH THE MAXIMUM RETURN TIMES REQUIRED BY FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 124, "ACCELERATOR CONTROL SYSTEMS."
THE SEAT RECLINER TO SEAT FRAME ATTACHING BOLTS ON THESE VEHICLE COULD LOOSEN, FATIGUE AND FRACTURE, ALLOWING THE SEAT BACK TO SUDDENLY RECLINE.
DUE TO A THIN CASE CASTING, AN EXTERNAL TRANSMISSION LEAK CAN OCCUR.
THE WINDSHIELDS WERE INSTALLED WITH INCORRECT WINDSHIELD OPENING PINCH-WELD-FLANGE PRIMER. THIS PRIMER WILL NOT PROPERLY ETCH THE PAINTED SURFACE OF THE FLANGE, ALLOWING THE WINDSHIELD TO SEPARATE FROM THE VEHICLE DURING A COLLISION. THIS DOES NOT COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 212, "WINDSHIELD MOUNTING."
TRUCKS WERE ASSEMBLED WITH THE LEFT-HAND LOWER CONTROL ARM TO FRAME REAR NUT TIGHTENED BELOW THE SPECIFIED TORQUE. LOW TORQUE ON THIS NUT MAY ALLOW THE ATTACHMENT BOLT TO LOOSED AND SUBSEQUENTLY FATIGUE AND BREAK. THE BOLT BREAKAGE CAN CAUSE THE LEFT HAND CONTROL ARM TO SEPARATE FROM THE FRAME.
THE SEATS HAVE BEEN ASSEMBLED WITHOUT BOLTS THAT CONNECT THE UPPER SLAVE HINGE TO THE SEAT BACK FRAME, OR WITHOUT BOLTS THAT CONNECT THE SEAT TO THE SEAT ADJUSTER. IN EITHER CASE, THE VEHICLES FAIL TO CONFORM TO FNVSS NO. 207, "SEATING SYSTEMS."
THE BRAKE PEDAL PUSH ROD RETAINER IS MISSING, MISPOSITIONED OR NOT PROPERLY SEATED.
SEVERE CORROSION DUE TO ROAD SALT AT THE JOINT OF THE STAMPED STEEL CENTER SECTION AND THE CAST OUTER SECTION CAN CAUSE THE SECTIONS TO SEPARATE.
UNANTICIPATED HEAT IN THE TRANSMISSION CAN FORCE THE TRANSMISSION FLUID OUT OF THE VENT TUBE.
LOOSE PIVOT BOLT HOLDING THE BRAKE PEDAL TO ITS SUPPORT BRACKET COULD DISENGAGE FROM THE NUT.
