[KBM5]

Hello Guys,

So today I was about to go on a drive with my 2018 F90 M5 and a noticed something unusual on my driver side Ceramic Break Rotor. I had a closer look and it looked like a piece of my rotor just fell off and left a hole (look at the pictures attached).

My car has 23,000 Kms on it, I maintain extremely well, I'm extremely cautious with it. The car has been tracked once in its life about a year and a half ago, I also often go for spirited drives, and the car is winter driven as well in Montreal QC, where it gets VERY cold. When I do use my breaks hard, I do give them a cool off period of at least 3-5 minutes of slow driving to air off the heat from the disks before completely stopping, and make sure I do not over heat my rotors. I use the car how it is meant to be used, mostly on highways for speed runs and or twisty roads a times, but again never abusing my breaks. Again I'm very cautious.

Therefore I have the following questions:

I was wondering what could've caused such an issue?

Is this something that can be covered under the warranty?

Can I still drive the car in the mean time? How safe is it?


Thank you guys for any help or insight you have on this issue!
