My car has barely 34,000 miles. I never had a problem until recently. It makes an awful noise on the inside of the car, but cannot hear it outside. The noise goes completely away once in a while. It sounds like something dragging, but there is nothing hanging down. When you apply the brakes it kind of vibrates more than if you were not applying the brakes.

Sometimes the noise is constant and sometimes it is silent. It has affected the gas mileage. And if I use the air conditioner it makes the noise go away sometimes. Not always. I have had the car completely inspected and they could not find any cause for the noise. They did hear it but could not figure out what was causing it. I am afraid to drive the car very many miles as I don't know if the engine is going to blow up or not. No warning lights have come on for the engine or transmission. I loved the car up until this happened. I need resolution to the problem.
