IN THE EVENT THE PRIMARY THROTTLE RETURN FAILS, FAILURE OF THE SECONDARY THROTTLE RETURN SYSTEM WOULD NOT PROVIDE PROTECTION AGAINST LOSS OF THROTTLE CONTROL.
A NEW PRODUCTION SECONDARY THROTTLE RETURN SYSTEM CONFIGURATION WILL BE INSTALLED.
STRESSES IMPOSED ON THE LEVER DURING TURNING MANEUVERS AND/OR IMPACT INCIDENTS, SUCH AS WOULD BE CAUSED BY CURBS OR ROAD SURFACE IRREGULARITY, REDUCE THE LIFE EXPECTANCY OF THE PART. THE STEERING LEVER MAY CRACK AND EVENTUALLY THE STRESSES COULD CAUSE THE STEERING LEVER TO BREAK.
A BROKEN STEERING LEVER WILL CAUSE LOSS OF STEERINGCONTROL WITHOUT PRIOR WARNING WHICH MAY RESULT IN A VEHICLE CRASH.
