I will also chime in and say that using Pilot Assist also wears your rear brakes as well. The car uses more rear brake bias when pilot assist is engaged. I’m able to feel it.
That and if you have the automatic brake hold engaged, it leads to wear also.
Volvo has had issues in the past with brake rotors and pads. They’ve changed suppliers but still the wear is a bit too much.
It’s solely this reason why I only use ACC/PAII in very parochial situations where brakes really aren’t required.
