We appreciate your outreach. As an initial troubleshooting step, when the error message "Unable to retrieve account details" appears after logging into the myChevrolet Mobile App, select “Log Off” instead of “Retry". Selecting “Log Off” will ensure that a new session is started, which refreshes the app. We do recommend waiting 5-10 minutes for services to sync. If re-trying log in does not work, please do not hesitate to let us know. We would be happy to take a further look into things.
