V60 polestar engineered braking problems

Did someone already have similar problems with the Brembo brake system of the V60 polestar engineed??? On the subject: Have the V60 since July 20 and relatively fast the problems (only) appeared on the front axle. When braking down from about 150 -170 km/h, the car vibrated on the front axle and also on the steering wheel. To better understand, it should be said that the brake pressure was already neat, but not starting in the area of the ABS. The visual test showed clear black “sliding” on the disks. These did not disappear completely, however, became again less. However, the problem occurred again and again, so that the car was then introduced to the workshop. The discs were no longer round after measurement! Result after some discussions & test drives: New disks and coverings!! After proper drive-in time the same problems occurred again. You can certainly imagine that my confidence in this so-called “performance” brake is no longer the best! Now the discs are exchanged again with coverings! Cost point after each exchange of about 3200,00 EUR. Of course, I did not explain the number of brakes here.
