2017 GMC TERRAIN Visibilitywiper Problems

I HAD MY 2017 GMC TERRAIN DENALI FOR TWO YEARS AND HAVE ALREADY EXPERIENCED TWO SERIOUS ISSUES. ISSUE #1-I NOTICED A BURNING SMELL, GRINDING NOISE, AND HESITATION WHEN DRIVING. I BROUGHT IT TO THE DEALERSHIP WHERE I BOUGHT IT AND WAS TOLD THAT THERE WAS A FACTORY DEFECT WHICH CAUSED SOMETHING INSIDE MY TRANSFER TO BORE A HOLE THROUGH IT.

GMC HAS BEEN PREVIOUSLY MADE AWARE OF THE PROBLEM AND I WAS INFORMED GMC ENGINEERS WERE AWARE OF THE PROBLEM BUT DID NOT HAVE A WAY TO FIX IT.
