Diagnostic report was wrong. Nothing is wrong with my car.

New Contributor

We received multiple emails from which advised that we had a major issue with our Engine & Transmission system.  The alert stated that there was a problem with our starter and our car could potentially not start.  It was noted that this required "immediate action" .  The car didn't seem to have any problems/issues with starting but since this was a proactive alert, we believed something was going wrong.  We set up an appointment at the dealership and just received a call that nothing is wrong with the starter on the car.  Now we are stuck paying $170 for a diagnostic that we never needed.  Has anyone had this issue and were you able to get your money back from Onstar?
