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.

FIXED (for me at least)

While in your car and preferably not near other WiFi sources, Go to Settings-> WiFi. You should see a network name something like "Car-DEC6" or something similar. Apple Carplay is using both bluetooth and wifi network to work. For me, I was able to play music, see maps, etc.. but no Siri voice commands were working. I turned off the following settings and everything has started to work again. Note: I also completely removed my car from CarPlay on the phone and the phone from the Car's system. Then re-added the phone to my car for CarPlay. This didn't fix the issue but I did do this first before disabling the settings below which did fix this issue. It's worked for days now.

On the Wi-Fi network described above, click the blue i to access the details for that connection. Turn off the following settings:

Private Wi-Fi Address
Limit IP Address Tracking

Once I did this, Siri voice commands started working again.

Similar issue, iPhone 16 Pro, 18.3, 2022 Jeep Grand Cherokee. The audible responses work about 1 out of 10 times after getting in car. Had no issues with the 13 Pro that I traded in a month ago.

Work Around on this: Independently I also saw it in one reply below.

Instead of saying, hey Siri text my daughter, which we know doesn’t work currently, I simply depress the microphone button on the steering wheel, and then I just say text my daughter. At that point all the prompts worked like normal and I could continue doing hands-free texting while driving.

That steering wheel microphone button is also good for any phone commands. I never really used it before until now and I’m finding it quite handy. Try it out!

I have a Subaru Ascent and also ran into the same problem with Siri NO longer working with iOS 18. However, there is an alternative, where you can still use Siri with CarPlay, but you have to press the activate Siri voice control button by just pressing and holding the voice control button on the lefthand side of the steering wheel on a 2019 Subaru Ascent. This does work. Once you release the button, Siri will respond to your request. At least it’s a work-around, until Apple releases a new software fix.
