Official summary
Flash: SRT Subwoofer Thump Noise After Vehicle Is Turned Off This bulletin involves re-flashing the Amplifier with updated software. The customer may experience after the vehicle is turned off a slow thumping noise coming from the subwoofer. This may happen only a few times or last until the next key cycle. This is caused by the amplifier waking up and then going back to sleep.

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.
