This is why automakers are balking at implementing CarPlay 2.

Chance Miller from 9to5Mac:

Apple released iOS 18.4 for iPhone users on with Priority Notifications, new emoji, several changes to CarPlay, and more. According to a growing number of users, however, the iOS 18.4 update has rendered CarPlay unusable in their cars.

In a thread on Reddit and elsewhere, iPhone users say they are experiencing a wide range of bugs with CarPlay since updating to iOS 18.4 this week. Multiple users say “Now Playing” information from CarPlay no longer shows up on their car’s gear cluster display.

Perhaps more importantly, however, some users are experiencing major connectivity problems with CarPlay in iOS 18.4. One user says their iPhone is “connecting and disconnecting over and over again” when using wireless CarPlay. Another user also says that iOS 18.4 “broke” their wireless CarPlay and made the connection “unstable.” One Honda driver says it “takes plugging and unplugging 5+ times or restarting the car to get CarPlay to connect” since updating to iOS 18.4.

Imagine if your whole instrument panel and all screens were completely taken over by CarPlay, and these bugs render your displays unusable.

Talk about a real cluster.
