    GMC app Diagnostics/Onstar

    I just had a display blackout, taillight and daytime running light failures. Repaired under warranty. My app "real time" diagnostics showed all good, even through the repair. No mention in my monthly diagnostics report. Useless? No useful response from GMC or Onstar.
