Hi all... I'm new to the group. I have a deposit on a pre-owned 2016 Acadia SLT-1. It has 42,706 miles on it. In doing research I'm reading about transmission and engine problems with the first generation Acadias. Could someone with the 2016 SLT please share their experience? Also, I'd anyone has purchased an after-market warranty that you recommend, please advise. Thanks.
