Mechanical Menace

Mechanical Menace is a quest and achievement/trophy in the Fallout 4 add-on Automatron.

Detailed walkthrough
The quest is started as soon as the player downloads the Automatron add-on and is level 15. The Sole Survivor is notified to listen to the new Caravan distress call that has appeared on their radio. Upon listening to it, they are notified to head over to an area near Wattz Consumer Electronics. Once there, they will find a multitude of robots battling it out beneath a highway. Once all enemy robots have been defeated, the player speaks with Ada and the quest ends.

Bugs

 * After reaching Wattz Consumer Electronics, and following the quest marker, you won't find any caravan or Ada. Walking to the quest marker will remove the Caravan distress call, and complete the objective, but no hostile robots will spawn leaving the Automatron unplayable.
 * A possible solution is to load an older save outside of the Cambridge area before starting the quest.
 * If you delete your saves so you don't have any outside of Cambridge you can uninstall Automatron, make a save outside of Cambridge then install Automatron again.
 * After eliminating the robots, Ada may be sporadically and quickly moving around in all directions, making it impossible for the Sole Survivor to interact with her.
 * For PC open the console select Ada and disable her, then enable her and she will behave properly.
 * If the distress call is not listened to immediately after the quest spawns, that station may fail to play, preventing the quest from moving to the next step and the quest marker at Wattz Consumer Electronics from spawning. It will still be possible to travel to the caravan's location and engage in the battle.  It is unclear whether this bug is triggered by fast travel or loading of an environment in general.
 * The next stage of the quest can be activated with the console command.
 * After killing all the robots, you are prompted to speak with Ada. Some players have experienced the inability to activate any kind of dialogue with Ada rendering the quest unable to complete.
 * You can skip this quest with the console command, and since talking to Ada is the last part of this quest you won't miss much.
 * Sometimes right after downloading the DLC and starting it on US copies of the game, the character associated to the DLC will speak a different language but the subtitles will come up in English.
 * Dismissing a companion to take Ada and then quickly asking them to follow you again (and thereby dismissing Ada]]) will cause to quest to instantly complete.
