Terrain SLT 1.6L Diesel

  • Automatic transmission
  • 117,000 miles

I have a 2018 GMC Terrain SLT 1.6L Diesel and since 70,000 miles it has been in the shop for the EGR, DEF system, Oil cooler and now the catalytic converter is throwing a code. I have contacted GMC customer service to file a formal complaint for the amount of issues I have had with this vehicle. I have spent over $5000 in repairs for the check engine lights that continue to haunt me.
