I have a leak coming from muffler, dripping black liquid. I complained at my dealer, they said it was not a problem.
Exhaust leak in connection from tail pipe to cat converter. Sounds like metal squeaking under vehicle when engine is running, but it is the sound of air whistling through leak. Water also drips from leak. Leak is under clamp that holds tail pipe up.
