Well I am sad to say my beloved 2018 GTS is getting a new transfer case on Tuesday. I took it in today for its 2 year service at 13,500 miles. They gave me a beautiful Miami Blue 2019 base to drive around in and I noticed that the loaner had more get up and go than my GTS. When I got home I was going to call the dealer and ask him, but he beat me to the call and he called me. He told me that he noticed a problem when he was driving it into the bay. They are going to order the part on first thing on Monday and hopefully have me in mine Tuesday afternoon. When he was explaining to me what he noticed, I go oh the transfer case is bad, right?
