Ever since the car reached about 10000 miles, the exhaust (I assume) has been really loud. It rattles, and at times, the noise is so loud and annoying, it's embarrassing. It is especially loud when I come to a stop at a red light, slow down behind other cars, or even if I am in park. I, for one, wouldn't think a new car should do that. Of course, dealerships are generally closed on Saturday, and by the time I get off work on weekdays, they are closed.
