I drive a Kia Rio 2022 and use CarPlay with it, both with my iPhone XS and with my wife's iPhone 17 Pro.
For the last week, the screen of the infotainment system has been failing to recognise my touches, and exclusively when using CarPlay.
The touchscreen is working perfectly fine with the radio and with the car's computer system, but it becomes unusable with CarPlay.
The CarPlay home screen shows a range of apps, the dots at the bottom to page through screens, and a KIA button on the first page. That single KIA button works fine to get back to the car's menu, while no other button works.
I have also noticed that, when CarPlay connects, I can still use my phone normally while it used to be that a big 'CarPlay' splash screen appeared to prevent me from distracting while driving. That no longer appears.
If I get a message or a call on the phone while CarPlay is connected, the projection doesn't work.
If I set up a route in Apple Maps on the phone and set it to Go, then the projection works but I cannot interact with the screen in any way.
I went to the dealer where they checked that the screen is working well and that there is no firmware update for the car. They suggested there may be a problem with the phone, but what can I do?
Thank you very much!
