One year ago my rotors had to be replaced because of severe vibration during the winter time, no less. Fiat Chrysler at the time told me it was because I was not driving it enough and the rotors warped on me during the cold weather, which was utter nonsense, I drove the car everyday. They eventually replaced the rotors but I had to jump through hoops to get it done. I now have the same problem and yes I do drive hard within the limits of the car, after all a QF is a performance car and the components should be up to par. I'm now waiting for their answer after more than a week has already gone by. They are under warranty for one year and a certain mileage threshold, . . . so far I'm very disappointed in the company looking for excuses to not honour their warranty, . . . do I need to replace the rotors every year?
