MyBuick app

Our team recognizes how inconvenient this loss of connectivity from your mobile apps to your vehicles is and would like to better understand how we can support in troubleshooting. As an initial troubleshooting step, we ask that you attempt to uninstall then reinstall the mobile apps to ensure you are running the latest version. Should this not prove helpful and the controls are not populating withing your app, you may need to conduct a Power Cycle on each vehicle. You can follow the below steps to do so.

1. Enter the vehicle and turn ignition on
2. Move vehicle to an open, uncovered area, if not already
3. Vehicle should run for at least 15-20 seconds
4. Shut off vehicle
5. Remove Key from ignition or Press start/stop button
6. Open the driver’s door
7. Only if Safe to do so, exit vehicle
8. Key FOB must also exit vehicle
9. Close Driver's door
10. All other doors, hatch, liftgate should also be closed
11. Lock vehicle doors using Key FOB
12. Key FOB must be outside of vehicle
13. Critical Step: Wait at least 15 seconds (Max 30).
14. This allows time for the OnStar unit and other electrical systems to turn off
15. At a minimum, the OnStar unit needs to turn off
16. Re-Enter the vehicle and turn ignition on
17. Move vehicle to an open, uncovered area, if not already
