Official summary
Some customers may experience a chatter (metallic knocking) noise from the underbody area when driving on rough roads. This may be caused by the contact between overlapping sections of the exhaust system insulators (Front No.1 and No.2) due to vibration. There is no mass production change planned.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
