Do? Write them to complain, but good lord, I can't imaging that they're not aware by now.
That said, no new firmware since Feb, so they seem overdue.
*edit: just checked again, new firmware - 1.07.
Sadly, no mention of this in "fixes":
This firmware update (version 1.07) contains the following improvements.
- Reduces noise that is emitted when using iPod sources
- Add QWERTY keyboard in AppRadio Mode
- Corrects a message that is improperly displayed when the system is turned off - Corrects an error that may occur when using SiriusXM Artist Alert feature
