Warning: hood open when vehicle is parked and factory theft deterrent security system is engaged, intermittently alarm goes off (even when remote control is not within range and no unauthorized entry is attempted). Similar to t-sb-0171-11 and t-sb-0208-10 vehicle equipped with a factory theft deterrent system may exhibit a condition where the security horn is inappropriately triggered when the vehicle has not been disturbed. A revised hood latch assembly (with internal component switch) has been made available to address this condition.
