NHTSA Complaint #11507341 — 2016 BUICK ENCORE

My drivers side door began to have a few small bubbles around the handle. I took it in and found out the door was rusting from the inside. Rain was getting in and rusting the sound bar. I paid $350 only to find out that the bubbles began to reappear in a few days. When the Buick Dealer took it back it, they discovered the problem. They said it was rusting inside the the door and that I needed a new door and that it was covered under corrosion. I want my $350 back due to the fact that it was covered and I never should have to pay $350.
