The manufacturer had not been notified. The vehicle was taken to a private mechanic who informed the contact that the heat shield had detached from the vehicle because the bolts were worn. No repairs were performed. The current and failure mileages were 120,000. A local repair shop informed the consumer, the heat shield located above the muffler had fallen off and was trapped between the muffler and the floor pan of the vehicle. The vibration noise heard was the heat shield rattling on the muffler itself. Updated 06/05/12
