Siri not working with CarPlay after iOS 18 Update

I upgraded to iOS 18 on my 13 Pro Max. So far all seems pretty good with the phone itself. However, when I connect to my 2019 Subaru Outback Siri does not work right. Siri works fine when not connected to CarPlay.

Here is the most obvious symptom. When the iPhone is connected to the Subaru with CarPlay, if I ask Siri to message, my daughter, her name will pop up on the car’s CarPlay screen and the little circular glow thing is there, but it does not take audible input.

It worked perfectly fine before the iOS upgrade. I find this a safety concern because I may want to respond or create a text message while driving without having to look at the phone or touch the phone.

Has anybody else seen this problem or suggest a fix for the problem? I did turn off the car unplugged the phone from the car and restart the car. At the same time, my rebooted my cell phone. That did not help.
