It is worth mentioning that the iOS 15 preview is all beta updates, and bugs like these are expected. This testing aims to make users test new updates before the official launch of the newest operating system. Users report a bug, and Apple will strive hard to refine their overall experience with the final product. It could avoid issues that might cause iOS CarPlay not to work.

Besides these, some possible causes that make iOS carplay not work include:

CarPlay Incompatibility

In some vehicles, a CarPlay indicator comes as a voice control button you see on the steering wheel. Otherwise, check the vehicle’s manual or reach out to the manufacturer’s website to get detailed information.

Siri App Problem

You need Siri to run the CarPlay app on your vehicle. If Siri has some glitches, CarPlay is surely going to be troublesome. CarPlay may also not work if Siri is not configured properly on your iPhone. This might also cause iOS 15 CarPlay to fail.

Settings configuration errors

There are some other configurations you have to make to enable CarPlay on your device.

Bluetooth connection or network errors

In this case, there’s a good chance that CarPlay stops working using the Bluetooth connection.
