Just took delivery of a new 2018 GT2 and discovered that three dark grey trim pieces are heavily discolored with a corroded peeling look (the very top trim on a door and the two trim pieces which flank the rear hatch glass). Dealer submitted work order for repair and told me he’s seen it before. I’m wondering if this is a common or ongoing problem and if Kia has re-engineered this trim. I guess I could consider a wrap if it reoccurs. It looks terrible.
