TECHNICAL BACKGROUND
A non-standard behavior of the previous Apple iOS versions (including all 14.x, 15.x, and early 16.x versions) causes the phone to fail to send screen data to the vehicle. Additionally, a hardware issue in iPhone 8, iPhone X, and iPhone XR models can cause the display to blank out.
PRODUCTION SOLUTION
Not applicable.
SERVICE
No repair is available at this time.
- Do not perform any repairs. Any repairs for this concern may be denied.
- For customers with iPhone 8, iPhone X, and iPhone XR:
The problem is due to a hardware issue in the WiFi chipset of the listed phone models. As those phone models are already out of production, no repair will be available. It is advisable to use a wired connection to use Apple CarPlay for those models.
- All other iPhone models:
Please inform the customer that this behavior is due to a bug in the phone's operating system (iOS). The iOS bug is fixed in iOS version 16.5 or newer .
