And that's three of us in this thread that have recently traded in an Acadia/Enclave to move into a '13 Denali.
We went from an Acadia SLT2 to a Tahoe LTZ a few years back. We had numerous issues from the headlights burning out and the headlight housing melting wires to the water pump busting. On our third water pump my wife was driving from Dallas to Phoenix and she was so mad she kept driving the damn thing, it was about midnight the middle of nowhere, in limp mode with it overheating. It did engine damage, yes I was frustrated with her, so we got it repaired, sort of and traded it in.
Anyways, I hope you guys love your Denalis. That's what we are shopping for but hesitant to purchasing because of the 2014s.
