Forward collision system coming on without warning

We too have had our 69 reg Arona do a sudden crash stop for no reason. Happened from about 25mph on a deserted road, fortunately, as anything behind would have hit us. Two of us in the front and certain there was nothing of danger to trigger this. Driver unable to prevent full stop, then stalled.
Took to dealer but staggeringly the car apparently doesn’t retain any error/use codes for such triggering of the emergency systems. No fault found. Worried that may recur when cars behind.
Mention above of adjusting sensitivity, but we have not found any such setting. Any hints where might find that?
Can manually switch off entirely - but takes some time going through the menus, and resets to default on each time restart car, so not practical to do every trip.
