Sudden warning from the pre-collision safety system for no reason

Does anyone else experience (very) rare occurances of the pre-collision safety system warning lighting up in the dash for no reason? It happened to me (Prado 2019 VX) for the second time yesterday, and it is kind of freaking me out a bit. The red warning with the word BRAKE shows up and it beeps, then it's gone within less than a second. My theory is that it's either a bug that flies into one of the sensors or water is temporarily covering it (the first time it happened a few months ago there was a bit of rain). I had no cars in front of me at the time.

What I am worried about is that it thinks there's a car ahead that I am about to run into and slams on the brakes, the way it's meant to in a real situation.

Hi Randog,
Yes, I experience the same think in my 202 GXL. So far a few times and always in the same spot in my local area. Scenario is driving along a straight in suburban streets at around 50kph and then moving into a tightish bend with cars parked on the other side of the road.
I figure that the technology senses the cars on the other side of the road just before I actually started turning, hence the warning.
So far the car has not braked, just falshed the big red warning on the dash. This disappears when I start taking the bend.
My car is brand new, so not likely to be bugs (of the physical kind), water etc.
