Good day all,

I have exactly the same issue. Bought my car last April 2023 import from Germany. I live and drive in the Netherlands.
Puma 1.0 ST-line 125 bhp, automatic 7 gear from December 2020 with 28.000 kms (17.398 miles).
It happened 3 times now on the high way with adapted cruise control activated within 2 weeks time period. No strange movements from cars infront of me, no warnings in the dashboard.
Yesterday, twice and eactly as discribed as in this topic. After it happens the first time yesterday, I turned off driver assist, but this didn't help obviously.
After the second time, I now have turned off the active braking, so trying to find out if this helps. Do not know this yet.
Curious to know if some knows what it is and how to get rid of it, as it is ptretty annoying, dangerous situation may arise and it scares me when the buzzing noise suddenly comes in.
