On Saturday morning 12/15/2014 start my card and heard a rattle noise on the engine, first time it make that noise since I bought it. On my way to work I started hearing the rattle noise again but this time it was louder I was driving around 40 mph when this happened. The car started vibrating and kept making the rattle noise on the engine. I just bought this car not even a week ago, and already started having engine problems. I took it to the mechanic and found out the the engine might need to be replace soon, since that's a common problem with this cars and that that's one of the signs that the engine might go bad soon.
