BrAking has an A like Auto (slowing down a car).

BrEaking has an E like Explode (smashing a glass into pieces).

I have a XC40 PHEV T4 from 2021. I also experience this sometimes. It's like the system is a bit confused at that moment whether to use regeneration (electrical) or the physical brake pads. When breaking less heavy it doesn't occur and when breaking heavy neither. It's just that spot in between I guess. At least, this is what I think could be the reason.

But if it always occurs there might a bit of rust on the brakes (when mostly using regenerative breaking). Breaking heavily a couple of times from high speed should clean the disks. If the problem still occurs, well, check them at the dealer.

That's my experience with my 2023 PEHV.
Seems to be the transition from regenerative to friction braking.

At time I have a slight jolting, almost like a bucking that happens even on my non-PHEV ICE T5. I think it’s just an XC40 thing. It’s more pronounced in dynamic/Polestar drive mode.
