## 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.
