If your seeing it too often it usually means your tailgating. It’s the collision assist, plenty of info in manual. Be safe!

I've had that come on and audibly buzz at me when just driving down the road with no one around. At least it didn't slam on the brakes on me.... thinking software, sensor, dirt, something making it malfunction.

ive had this happen to me also, with no one around, and i have noticed when this does happen, i have usually hit an odd dip in the road. i am guessing it was an angle of what the system was looking at was thrown off and it saw the ground as an incoming wall? i have no clue... but it can be annoying.

like you said, luckily the brakes didn't activate on their own.

if you get a bug or dirt on there it will also cause it to go off, same with ice and slush.
