Official summary

Special Coverage. Certain vehicles listed above may have a condition that could cause the mounting bracket on the front exhaust pipe to separate from the pipe. If this condition occurs, a hole may develop in the exhaust pipe at the bracket location, and a rattling or increased exhaust noise may be heard. This special coverage covers the condition described above for a period of 15 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. For vehicles covered by Vehicle Service Contracts, all eligible claims
