If you're having trouble with the myChevrolet mobile app, we recommend that you uninstall then reinstall the mobile app as an initial troubleshooting step. This will ensure you're using the latest most up to date version of the app. If this doesn't work for you, or you continue to have difficulties, please send an email to socialmedia@gm.com with your subject line as ‘ATTN: OnStar Community/12' so we may further assist.
