Radio station selection (AM, FM, SiriusXM®) changes unintentionally after turning the ignition on. Audio source cannot be changed. Diagnosing according to MGSS online does not solve the problem.

SummarySome customers may complain about color discrepancies (brightness differences) of the image displayed on the screen when using the 360°view monitor. As this phenomenon is not a system failure, do not make any repairs or replace any parts. Explain the cause of this occurrence to the customer as follows: The 360°view monitor is a system that provides a complete picture of the vehicle surroundings by combining the pictures captured by 4 separate cameras. These cameras are installed in the front, rear, right and left sides of the vehicle. Each camera has a color adjustment function (white balance) that operates independently from each other, which can result in color discrepancy when the combined picture is displayed on the screen. This is especially true when one of the cameras captures more green objects than the remaining cameras.

SummarySome customers may experience the rear audio subwoofer sound pauses intermittently at a high volume level. When the volume level is lowered, the subwoofer audio sound returns to normal. The actual volume level where the concern occurs 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 is due to the improper control software of the audio amplifier (Bose® audio system). To eliminate this concern, the control software has been modified.
