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.

Since loading iOS 18, CarPlay in my 2023 Subaru Forester has not worked. Keep getting the Subaru screen to disconnect, wait, and reconnect. After doing this cycle about a dozen times, CarPlay still does not appear.


Tried different USB-C to USB-A cables with my iPhone 15 Pro, and the same Subaru screen appears . . . Disconnect, wait, and reconnect. Not thinking its the cables.


Even went thru the ‘forget this car’ by removing the car from my iPhone to no avail. After removing the phone, and when the car does appear to connect, it does give the screen on my phone about accessing CarPlay while phone is unlocked . . . But the disconnect, wait, and reconnect Subaru screen appears shortly thereafter. This tells me that it wants to connect and engage CarPlay; but something is still not allowing it to engage.


Also went into the Screentime settings to ensure CarPlay was checked to be an allowed app in the content and privacy restrictions. Still, the same disconnect, wait, and reconnect Subaru screen appears.


It seems there is something in the new iOS that is not allowing Subaru’s infotainment system to fully engage CarPlay. Please help!

Having the same issue with my iPhone 13 paired with a 2021 Forrester. 




i think it’s a Hey Siri / Bluetooth/ IOS 18 / CarPlay issue. Bluetooth /IOS 18 works, so does it work when I use the steering wheel controls with Bluetooth / IOS 18 / CarPlay, but have never ever ever used the steering wheel controls until today




Tried re-paired my phone to the car and same thing
