The plastic on the steering wheel, between the radio controls on the right, the cruise on the left, and the Buick symbol in the middle is very cheap looking. On the Acadia it's chrome, it looks much nicer. The other thing is that GM cut corners on the header liner area and overhead light panels. A nice touch would have finished the area where the lights and Homelink transmitter with the same wood and chrome trim as the rest of the car, instead they took the cheap route and used the same parts as the Outlook and Acadia. If I wanted a Saturn, I would have bought one.
I also have a rattle that seems to come from above the instrument panel. I have 130 miles on my Encalve. QuietTuning indeed. Yes, I can take it into the dealer and let some tech tell me I'm crazy or spend 8 hours tearing about my IP, but I shouldn't have to. I'm more worried about a tech damaging a new model vehicle than I am about the rattle.
Nitpicky? That's a pretty subjective term but if Buick expects to complete with Mercedes and Lexus, they need to focus on this stuff. And yes, that is their expected competition as GM compares the Enclave directly to MB and Lexus in it's advertising. These are small things a previous Chevy/GMC owner overlooks as 'nitpicky' whereas a Lexus/MB owner says 'cheap'.
And yes, the door locks could have been chrome or moved to the door handle itself. Not nitpicky.
