iOS27 Siri slow in carplay

When I’m using iOS 27 carplay and ask siri to perform a simple task such as send a message or read a message she seems to need to go off to the internet and responds very slowly. Previously dimple commands seemed to be processed on device. And after I dictate a message (which is much more accurate to give her credit) she gives a whole story about sending the message to first name lastname using messages. Why has all of this extra sentence been added when it was fine in the ios 26 version?

I’ve disabled Siri AI and gone back to classic Siri, which is much more responsive when driving. I’ve got Siri AI on the MacBook if I ever need to use it, but its just not responsive enough while driving. Even a simple yes or no voice response was sometimes timing out.

I love the functionality of Siri AI in most respects, but have to agree, in CarPlay, it’s very slow and frequently times out. Before going backwards to the old Siri (is that even possible?) I’m going try a few things in settings.

  1. changed Siri pause time to “default”
  2. Increase speak rate from 100 to 138%
  3. Changed to “always silent” responses”

then in responses toggled silent responses on for CarPlay

Fingers crossed!

I'm finding everything to be slower in iOS27. Siri, maps, and especially the connect times. With all the talk about CarPlay improvements I'm not impressed at all. Doesn't matter if I am doing wireless or wireless, still much slower, especially the connect times.

My CarPlay is a hot mess since the update. Slow. Reads EVERYTHING back before sending even though I ticked send automatically. I turned off the Siri AI and it’s still horrid compared to before. 17 ProMax.

Since upgrading to iOS 27 responses from Siri in CarPlay as very slow on simple requests like “send a message”
