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.

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!

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!

Interesting to know that you were not using the steering wheel controls for handsfree operations in your vehicle. Never occurred to me that users with steering wheel controls weren’t using them. Seems like if you were using Hey Siri before while in the car you may have been technically it using CarPlay for those functions and were instead using Bluetooth with the phone treating the car speakers like a bluetooth headset (which technically is what people that don’t have CarPlay in their vehicles but can pair their phone via Bluetooth would do). Nothing wrong with that of course but just surprised
