cracks in front rotors

ok ... so they are slotted ... so they got some cracks starting from the holes in them ... so the cracks are about 1-2 mm average .. top crack about 4mm i guess

any ideas ?

the care has 20 000 km on it ...

If they are stock, they are actually cross-drilled not slotted. That sometimes happens to cross-drilled rotors. Could be caused from driving in cold weather or hot/ cold cycling. I had some Zimmermans that cracked like that.

To my knowledge, MB only covers brakes for the first 12k miles... Would be 32,186km if I'm not mistaken. Take it to the dealer and see what can be done!

Take it to the dealer, I suspect warranty will cover it. MB covers break ware, yes. Howevery this is something different.
