Official summary
Some vehicles may experience unusual noise coming from inside the front door panel when playing the audio system. This is caused by the damper coming off the speaker frame due to corrosion. To correct the issue, a plating process was added at the supplier beginning on November 13, 2015.
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.
