    Loud rattling noise coming from under the rear of the car. Have not had it diagnosed yet, but souinds like this may be the cause. The noise is not constant. Usually at slow speeds. Independent of whether the car is warm or not.

    Heat shield cracked. Had a muffler shop to weld it. But, after about 10k miles it has cracked again.
