Bulletin Summary
Some customers may experience rear subwoofer audio sound pauses intermittently at high volume levels. When the volume level is lowered, the subwoofer audio sound resumes. The actual volume level may vary depending on the audio source. If the audio source consists of many low frequency (40 - 70 Hz) sounds, the concern may occur at volume level 35 or higher. This concern may be caused by improper audio amplifier control software. To eliminate this concern, the control software has been modified.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
