As was mentioned by
@Pitre in the other thread, this is the collision avoidance system. Can't say it's ever bothered me and has only gone off a handful of times when I've had to quickly brake because either someone else has bad situational awareness or I've had to do it for one reason or another.
Do you drive excessively quickly and brake hard? If so then that might be causing it. You should be able to adjust the sensitivity options in the settings menu on the small screen in the dash under "Assist."
