THE BASE OF THE ELECTRONIC ACCELERATOR PEDAL IS MADE OF DIE CAST ALUMINUM. THE BASE MOUNTS DIRECTLY TO THE CAB FIREWALL. THE CAB FIREWALL IS NOT RIGID ENOUGH OR FLAT ENOUGH AT THE MOUNTING SURFACE, CAUSING STRESS ON THE ACCELERATOR BASE THAT WILL CAUSE THE MOUNTING PADS ON THE BASE OF THE PEDAL ASSEMBLY TO FAIL AND TOTALLY SEPARATE FROM THE FIREWALL.

Consequence Summary:
THIS CAN CAUSE LOSS OF SPEED CONTROL, DRIVER DISTRACTION, AND RESULT IN AN ACCIDENT.

Corrective Summary:
DEALERS WILL INSPECT THE ACCELERATOR PEDAL ASSEMBLY AND INSTALL A PLATE BETWEEN THE ACCELERATOR MOUNTING BASE AND THE FIREWALL ON THOSE UNITS WHERE THE BASE IS NOT BROKEN AND HAS NO VISIBLE SIGNS OF A CRACK. IF THE BASE IS BROKEN OR CRACKED, THE ACCELERATOR ASSEMBLY WILL BE REPLACED WITH A NEW REDESIGNED ACCELERATOR PEDAL ASSEMBLY.

Defect Summary:
FOUR COMPRESSION BACKPLATE RETAINING FASTENERS ON THE TURBO-CHARGER WERE TORQUED ONLY HAND TIGHT.

Consequence Summary:
WHEN THIS OCCURS, ENGINE RUN-ON AND SUBSEQUENT LOSS OF OPERATOR CONTROL VIA THE NORMAL THROTTLE MECHANISM CAN OCCUR, WHICH COULD RESULT IN A VEHICLE ACCIDENT.
