To resolve the issue of charging stations appearing grayed out with an exclamation point in the HondaLink app, follow these steps:

5. Check Battery and Vehicle Status: Sometimes, issues with the vehicle's main battery can also affect app functionalities. If you suspect battery problems, consider visiting a dealership for an inspection - learn more.

6. Try Alternate Mapping Apps: If the HondaLink app continues to show issues, consider using other mapping services like Google Maps to locate charging stations as a temporary workaround while addressing the HondaLink issues.

7. Contact Support: If the problem persists, contact Honda customer support for detailed assistance. They can help with specific diagnostics related to your vehicle and the app.
