Problem with wireless CarPlay

Here's what usually fixes wireless CarPlay on a 2022 Encore GX. Work through these in order:

1. Check the iPhone basics

- Bluetooth ON and Wi-Fi ON (Wi-Fi doesn't need to be joined to a network, just on)

- Airplane Mode OFF, any VPN OFF

- Siri enabled (Settings > Siri)

- CarPlay allowed (Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps)

2. Restart both

- Restart the iPhone

- Turn the car off, open and close the driver's door, wait 2-3 minutes, then start it again

3. Confirm CarPlay is on in the car

- Touchscreen: Settings > Apps > Apple CarPlay = ON

- Check the Phones list and make sure your iPhone is listed with CarPlay enabled

4. Forget the connection on both sides

- iPhone: Settings > General > CarPlay > your Buick > Forget This Car

- iPhone: Settings > Bluetooth > (i) next to the car > Forget This Device

- Car: Phones list > delete your iPhone

5. Re-pair from scratch

- Car in Park, press and hold the voice button on the steering wheel

(or add a new phone from the car's Phones menu)

- iPhone: Settings > General > CarPlay > Available Cars > select the Buick

- Confirm the matching code and tap "Use CarPlay"

6. Test with a USB cable

- Plug into the car's data USB port with a good Apple-certified cable

- If wired works but wireless doesn't, the problem is on the car's Wi-Fi side

- Plugging in often triggers the prompt to set up wireless again

7. Update and reset if still stuck

- iPhone: Settings > General > Software Update

- iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

(this erases saved Wi-Fi passwords)

- Car: Settings > System > Vehicle Software > Updates

- Last resort: factory reset the infotainment under Settings > System

(wipes paired phones and presets)

If the CarPlay icon on the Buick screen is greyed out and wired CarPlay still works,

the fault is likely the car's Wi-Fi/hotspot module rather than your phone. Other

Encore GX owners have reported this, and it needs a dealer visit to check the

infotainment module and software. Use a wired connection in the meantime.

Menu names can vary slightly depending on your software version.

Re: "Problem with wireless CarPlay" ... "stopped working"

There are so many different vehicle manufacturers, vehicle models, iPhone models, and iOS versions in use ... it seems there is no "one-size fits all" solution when trouble-shooting.

Each case may have a different cause, and therefore the solution often depends on understanding what causes the particular effects people experience with CarPlay.

The solution that works for one, isn't needed by another, and we have little info. to go on so far, from your post to us.

Eg: The firmware for the vehicle's stereo / infotainment system may need to be updated to remain compatible with the iPhone.

(The vehicles manual, or the manufacturer's support website likely has the firmware update details.)

or

Perhaps it is the iPhone's iOS version that may need updating.

ie: The newest version of iOS 26 is currently iOS 26.7.1

and "This update provides security fixes for your iPhone".

or

The newest version of iOS 27 is currently iOS 27.0.1

Apple support provides a troubleshooting article (link below) that may be helpful to you ... ie: there are some step-by-step details, if those are relevant to what you are experiencing with CarPlay.
