Unfortunately I had an accident with my 2018 718 CGTS during a track session at the Bahrain International Circuit. I was doing a short session at the track (30 minutes session) and after 25 minutes of tracking the brake failed, I was at the straight lane and when I had to break and take the turn, there was no brake at all, i tried pressing couple of times but there was nothing, so my car went into the track gravel and i had to downshifts with the paddles to slowdown the car before I hit the track fence at the end, which causes the damages you see in the photo. Unfortunately my insurance company does not cover the damages because the accident happend inside the track. The car now sit at the dealer to assist the damages. I asked them to check the car log to see if there is any brake technical failure, I did not see any warning messages before or during the track session, it just happened suddenly (zero brake ). I appreciate your input in what might caused this issue. the car has 27,000 km with almost 1 year and a half of ownership (still under warranty), last service done at 15,000 km at Porsche dealer.
