The transmission would not shift . The RPM's were always high . They tried new shift modules and other stuff to no avail . If they didn't buy it back , then by law , it was a lemon anyway and they stood to loose a lot more . That said , they were great to work with and it was a quick process . We had lost all faith in GM but their actions have turned that around . In fact , I was so impressed with the way they handled it that afterwards , I recommended a fleet deal to my employer for 10 Colorado's , which they are currently finalizing .

Just leased a 2013 SLT1 2WD last week and drove it from Phoenix to Laguna Beach CA. Two adults, three kids, lugage, stroller boogie board etc.., average speed 75+. The trip home included a couple hundred pounds of beach sand and more luggage. Had room for all, locked the cruize on 85 for long streaches and passed a couple 18 wheelers at around 95. Average MPG for the trip was 18.5. Bigest complete, the GPS touch screen froze several times and takes multiple touches to respond.

I bought a 2013 GMC Acadia early this year and feel the same way you do. I am disappointed at GM engineering, the engine has plenty power to have two diving modes, standard for towing and heavy foot folks, and economy for easy driving. The engine stays at high RPM before downshifting for easy driving and will run around 2000 RPM to coast at about 75 MPH. If you want to make up to 26 MPG, keep the RPM between 1400 and 1600; the only problem is that the max speed you will reach is about 55 MPH.

I agree. My 2007 Acadia can get up to 26 MPG on highway with super unleaded and my average speed is from 65-72. I don't count on display gas mileage meter but calculating by filling up then setting a trip odometer to zero. Drove a long trip on highway from Houston to Dallas. On the next fill-up, I take the total miles then divided total of gallons just filled-up. In city, my Acadia can get around 16-18 GPM. I always try to run over 42 MPH in order to have a transmission shifted to 5th or 6th. Driving under 42 MPH will make it gas sucker as you mentioned.

I have a 2013 Acadia and get 17 MPG city driving and 24 on the highway. Have to drive about 1800 RPM.

We bought our 2011 Acadia (AWD) thinking it would have better gas mileage than our 2006 Jeep Grand Cherokee. We've been tremendously disappointed and I would not buy another Acadia. The window sticker said 16 mpg city and 23 highway, and we've been no where near that. City runs about 10 mpg and highway is about 16. I've asked the dealer to look at it twice and they told me there's nothing wrong with it. "Must be the way you drive it, your driving mix, etc...". I understand the projected mileage is a range, but to be off by 35% on city 30% on the highway is ridiculous. It's not an apple to apple comparison, but the projected mileage on my 2012 Ford Focus has been dead on.
Another annoyance is the interior fit and finish. There's a squeak in the headliner of our Acadia that the dealer hasn't been able to find. It's been squeaking since about 5K miles and we have 35K on our Acadia now. Also have had some problems with interior plastic interior trim pieces breaking and falling off. Granted, it's just a squeak and the dealer replaced the trim pieces under warranty. But, I expect a lot more from $40K vehicle...

I have the 2013 Acadia and so far I've only had to fill up every other week. That's about the same I was doing with my Pontiac Torrent.
At 620/630 miles on the odometer the average MPG is 15.1 ( I have yet to reset it though since I bought it) But to me that's pretty good for a new car. It all depends how it's been driven.
I've seen other people who get 21 - 23 MPG on their Acadia's.

I have a 2011 Acadia SLT-1 2WD that we bought a little over 2 years ago. I have approx. 27K miles on it and have never gotten anywhere near what the sticker says (17/24mpg). I have taken it to the dealer 4 times and each time they say "everything is computerized and if there was anything wrong, the check engine light would come one". "it has to be driving habits/etc.".
I don't have a lead foot and am a normal driver, but when your combined city/highway economy is approx 15/mpg, there is something not right but no one can seem have an answer for the issue. very frustrating. it's almost like it doesn't shift correctly sometimes, there is a "slip" in the shifting, or somethign like that. not sure what else to do.

Acadia can get good MPG if you drive it slow. It will never get sticker 23 MPG at 65-70 mph, but may get it at 50-55 mph.
