Apple has yet to officially acknowledge an issue with CarPlay and iOS 18.4, so it's unclear if and when a fix will be available.
The iOS 18.4 update was released a few days ago, bringing several improvements. When it comes to CarPlay, the most significant change has to do with the interface, which now displays a third row of icons, but only on vehicles with a larger center display.

For many drivers, especially those who spend time in the car every day, CarPlay isn't just a "convenience." It's a way to:
- control music, navigation, messages,
- stay securely,
- have access to Siri and apps hands-free.
Therefore, improper operation of CarPlay can really affect the user experience and in many cases road safety.
