Hi, we were driving up in the pyrenees in or 2022 MP when i sensed smoke from the brakes, not too much but still and they were really hot. After a short stop and cooldown we carried on but after a while the handbrake warning lamp started blinking. The manual told us to call Mercedes wich we did. After sime discussion with a mechanic he told us to drive 1 km and check if the brakes got really hot and to get to a service center a.s.a.p. Now we are in a huge Merc Center outside Barcelona and they tell us the brakes are gone and that its not on the garantie...my question is how can this happen on a new car after only 12400 miles. And we were really attentive on the brakes on the slopes...any tips on how we handle this?
