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.

CarPlay is the Issue here:


For reference...

Troubleshooting CarPlay:


A. Don't Use a Charing Cable:

There's charging cables, and then there's cable just for data transfer. So, try a different cable; one that is not intended for data transfer. Charging cable amplify the voltage.


B. Driver's Manual:

Read your driver's manual to find out more about syncing this.


C. Try being in Park:

For many, they must have their automobile in park to get this to all pair.


D. Some Links:

Appreciate the response. I think I’ve addressed all of your potential solutions there. To clarify specifically, CarPlay is working fine with the iPhone 16, using the right cables (aware it’s common for people using the wrong ones…), syncing correctly and it’s purely the 17 device with ios26 which has problems.


And the above seems to be becoming widely reported quickly looking at X and Reddit.
