loud noise when starting vehicle, sounds like a cheap motorcycle! Calling dealership today for an appointment.
Catalytic converter was replaced. Paid for by dealer, even though I was out of warranty. (apparently it was a known issue)
Small crack on top of cat. Some exhaust leakage, but very minor. Did not affect operation, did not repair.
Not covered under recall, have not yet fixed problem. Thinking of welding.
