Siri CarPlay messaging caught in loop (2025 Armada SL)

I purchased a 2025 Armada (SL with Propilot 2.1 package) on July 27, 2025. I have the same issue that others have posted about where Siri gets stuck in a "listening" loop when initiating or replying to a message. For me, it now happens on nearly every start-up.

When I initiate a "text" message through Siri, or reply to one, Siri gets stuck in a loop. She will respond by saying "What do you Want to say to Joes---" (cutting off the contact name), then goes silent to listen but hears nothing. After a period of time she will come back as say "it says" as if to read back what I said, but then goes silent again. This will continue to loop until I tap cancel or it runs its course of about 15~ loops. If it runs its course CarPlay will sit there with the Apple Intelligence "glow" around the screen but nothing else going on.

I have tried using the "require Siri for interruptions" setting in accessibility. I've tried muting the volume before using Siri. I've tried having the air conditioning/blower completely off. I've tried completely turning off WiFi AND Bluetooth (from the respective setting menus) and using wired CarPlay. I've tried adjusting the speech pattern settings, the length of time settings, etc. and nothing works ... except one thing.

If I reset the headunit (hold the Power/Mute Button in the Volume knob until the unit powers down and back on) then Siri will work correctly for a period of time but eventually it will go back to getting stuck in the loop until I reset the head unit again.

I'm running an iPhone 16 Pro on iOS 18.6.2 (and previous versions). I've tried with my Daughter's iPhone 15 Pro Max and it does the same thing.

I have noticed in my other vehicles when Siri is active for messaging the background sound is muted or severely turned down (automatically by CarPlay) yet in the Armada it doesn't do this. However, as I mentioned before, even having the radio/Carplay music completely off doesn't stop Siri from looping.

I have a case open with Nissan as well and the last time I spoke with Apple about this the rep documented my case and said he had found some reports of this.
