iPhone 17 CarPlay Disconnects and won’t work

It seems iOS 26 on the iPhone 17 pro has a CarPlay issue. whilst CarPlay comes on and looks like it will work fine, after 20 seconds or so it just disconnects.


And when posting on reddit, it seems many people are having this issue whilst their devices worked fine on CarPlay with the 16 etc.


Ive personally tried using a beats CarPlay usb A to usb C cable, but also the Apple official USB C cable with a high speed usb a to usb c adapter, and both have the same behaviours. Worked fine with iPhone 16 but iPhone 17, disconnects.


I’ve tried rebooting the iPhone, deleting the CarPlay history, deleting the cars CarPlay history and all to no avail. Looks like it’s working and then boom, disconnect.


it’s acting like the USB port is too low powered for the data connecting of the iPhone 17 but that doesn’t sound right as clearly it works for a lot of people. Someone on X mentioned it might be due to the phone messing with the new wireless chip when connecting to CarPlay.


either way, it’s annoying and just doesn’t work for me. And no idea how to solve at this point seeing as it can’t be the cable and it doesn’t sound like the cars USB port is the issue either - given lots of users having issues sounds like it could be an ios26 issue?


thanks!


p.s I’m seeing reports of identical behaviour with wireless CarPlay interestingly though in my case I can’t test wireless CarPlay.

Great news folks - I just downloaded i.OS 26.1 ( the very newest upgrade, released 3 November 2025) and CarPlay now works fine! No connection/ disconnection issues.


So kust make sure your CarPlay unit has its latest software, update your iOS to 26.1 ( NOT iOS 26.0.1) and the CarPlay will connect & stay connected.

Yippee!

I've also downloaded iOS 26.1 but my results were slightly different. Yesterday Nov. 5th CarPlay disconnected again, moments after I started playing a podcast. It did however continue the rest of the day when I was using it. Hopefully the one time was a glitch and everything will continue working as I have a long road trip planned for next month and plans for listing to a couple of books along the way.

I have a 2021 car and I’ve always used it with a dongle because it only supports connection via USB. Until recently, it worked normally, but now it only connects whenever it feels like it.

I’ve already paired it again with both the dongle and the car, but the next day it won’t connect again.

Was the connection feature an extra option at the time of purchasing the iPhone 17?

With the same dongle Android auto works fine.
