We recommend pushing your blue OnStar button to have an On-Demand Diagnostic performed. You can then compare the results of this to your OVD email. Some diagnostic information can be time sensitive and/or can resolve from the time the email was sent to the time the Diagnostic is executed. If this is a recurring issue, our team can look into creating a case with our Technical Teams to have it resolved. To do so, please send an email with additional details to socialmedia@gm.com and be sure to have "ATTN: OnStar Community/CM" in the subject line.
