For two months I have not been able to us the "map" to locate my vehicle,a 2019 Sierra truck.

This is not the experience that we strive to provide with the Guardian app. Thank you for bringing these location concerns to our attention. If you continue to have trouble and would like our social care team to take a further look into things, kindly email us at socialmedia@gm.com with ATTN: OnStar Community/DJB in the subject headline. We would be more than happy to take a further look into things on our end.
