I don't think that you are a mouthy jerk at all. I think your complaint deserves to be heard and given attention in this forum.
Let's see if the girls from GM headquarters offer their usual apologetic, scripted response in reply.
Also, some of us are becoming tired of hearing the predictable response that we are being too hard on the GM "customer care" reps here. All that they ever post is their useless, corporate regurgitations.
Apologies may be meant to sooth. But no apology has ever repaired an automotive defect.
