Some 2020 Explorer/Aviator vehicles may exhibit a rattle type noise originating from the exhaust flexible pipe. This may be due to the natural harmonic frequency of the pipe. To correct the condition, follow the Service Procedure to install a worm gear clamp over the exhaust flexible pipe.

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.
