Many iPhone users are reported to have problems with carplay functionality after updating iOS 18.4 based on complaints. reddit And elsewhere.
The most comprehensive issue affects vehicles equipped with carplay instrument cluster integration. Some users stated that after installing iOS 18.4, Carplay no longer displays information about the song playing on the instrument panel of its car.
Instrument cluster bugs have been reported in many vehicle models including 2025 Honda Civic Hybrid, 2025 Mazda CX -30, various 2024 Honda models, several Volkswagen vehicles, 2023 Audi S3, and 2023 Nissan Frontier.
Meanwhile, many users have complained that the carplay fails completely to launch after update, which requires many re -combination efforts – sometimes up to five attempts – before the system work. Others report broken Siri audio functionality that remains despite resuming both their iPhones and vehicles.
Users say they have attempted standard troubleshooting stages such as devices reboots and system resets, but in many cases these workarounds have not resolved the issues. Problems appear directly to the iOS 18.4 updates, as the affected users report that everything works properly before installing the latest version.
Apple has not yet accepted any carplay issues with iOS 18.4, so it is not clear whether the fix is in work. Apple released iOS 18.4 earlier this week, and the only notable change in Carplay is that the interface now shows the third line of the icon (from the first two rows), but only on vehicles with a large display center.
