Official summary
Some customers may complain that the warning sound in the passenger compartment (notifies i-ACTIVSENSE warnings, seat belt warning etc.) is too loud. Some of the volume settings in the notification and warning amplifier are not properly set. The control software of the notification and warning amplifier has been modified to eliminate this concern. CX-70 / CX-90 NOTE: This repair is also applicable for a "WARNING MESSAGE FOR AVAS MALFUNCTION WITH DTC B1A03:2B" concern.
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.
