I am surprised. I have had only good experiences with Onstar (when their signal could reach me). I once had a flat which (because of physical limitations) I could not change by myself. I am a preferred customer with AAA supposedly entitling me to faster response time) so I called them and then Onstar. The Onstar guy showed up first, so I cancelled the AAA call. The Onstar kid got me rolling in about 5 minutes. Onstar did have a hard time hitting my vehicle in Yosemite valley in the analog days.
