Brought the car in August 2011. At every service I would report of knocking noise as if the car was in need of oil. I was repeatedly told that there is/was nothing wrong with the car. Again in December 2013, mileage was 17,000 I complained (very loudly) about the noise. . . . One of the tech's took it for a hard test drive and blow up the engine. They said my engine was gone and they needed to replace it which they did do. The only thing I have to ask should the warranty start over? I copied and pasted this but added my own stuff to it! you cannot detect a bad engine barring with a computer sensor. . . . You have to use your brain. . . . . . . Something that has gone with the times:(.
