I've experienced the same event. I'll be driving along and the word BRAKE appears in the driver's information panel for seemingly no reason. Can't figure out whats activating it. I'm not that close to another vehicle.
My PP does that occasionally. I've noticed that in each instance I've been driving on a two way road, I am on a curve, and there is oncoming traffic on the other direction lane. The collision avoidance system at work. So far it has not applied the brakes, I suppose the split second change in the oncoming traffic resets the collision system.
