My new Ford Puma, less than a year old, has pre collision assist installed - no idea what it did but I knew it was to do with the sensors picking up objects ahead of the car and alerting me.
Last Saturday, I was driving up a slight hill, the road ahead was totally clear with no other vehicles in either direction when suddenly, without warning, my car did an emergency stop and an alarm sounded! I was absolutely terrified and shaking, I saw an flashing icon on the dashboard about pre collision assist which told me how to restart the car which I did and I gingerly drove off.
The only thing I can think of is that the sensors were not aligned correctly as I was going up a hill and a cyclist, approaching the junction on a side road, had triggered it. The cyclist stopped at the junction though and made no attempt to cycle across in front of me - I had seen the cyclist anyway.
I read the manual and have now disconnect this feature until I can discuss it with the Ford garage as I’m concerned about it happening again, had a car been behind me, I doubt that it would have been able to stop in time.
It felt very odd when the car took over control from me!
