Service bulletin 09-039-25
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Some customers may experience that the right subwoofer audio sound pauses intermittently at high volume level. This is caused by improper control software of the audio amplifier (Bose® audio system). The audio amplifier’s power IC may sometimes mistakenly detect an over-temperature condition and shut down operation to prevent damage to the IC. To eliminate this concern, the control software of the audio amplifier has been modified.
