2008: “Why has my 2008 Gmc sierra not been repaired. I have lost faith in general motors. My next new vehicle will not be a GM product as was my last purchase in 2018. I haven't driven my vehicle in over 3 months and when I do drive it, its just to pick up the fallen limbs in my 6 acre yard. I have not had an incident. What should I do?”
