I am experiencing this issue currently. I am at 91000 miles and the expansion exhaust pipe must have cracked inside the wire mesh where you have clamps and is allowing a strange resonance. The dealer claims they have not seen it and the warranty will not cover exhaust since I am over the bumper to bumper. I recently just had a code P2C7A which is more than likely oxygen being detected causing the light. I am going to get the expansion pipe section replaced and then get the code checked out to make sure it isn't something else in the emissions system failing. I have about 9000 more miles of warranty for that equipment. It is frustrating there is apparently an issue and we have to pay for it. I am posting this for someone else suffering from this failure.
