My wife's vehicle, she likes it, its safe and good in snow with AWD, looks nice, lots of interior room, etc. I'm a little more picky - gas mileage pretty bad, the head rest leans too far forward, so not comfortable for me in drivers seat, and at 58K we had to get the timing cover resealed because it was leaking oil. Luckily, covered under powertrain warranty so did not cost me a penny. Also, very minor, but the rubber footing on the emergency brake popped off. I popped it back on and its been fine ever since. I have a 2005 Camry with 270K miles and no issues (knock on wood). Starting to worry about this vehicles longevity, don't think it will hold up as well as the Camry.
We purchased the 2011 Denali brand-new, kept it well and were rewarded with poor quality. The first year was fine--the lack of technology was a nuisance, but the car fit my very tall family, so I was willing to overlook that. But simple things like the non-qwerty keypad in the CD-based nav system really wore on me. GM stayed solvent by skimping on technology, and it's painfully apparent in this model year. Our '06 BMW 3-series has better technology.
Now at 36k, it's falling apart all over!
Interior space, decent exterior styling
Quality--the struts for the rear hatch broke 400 miles after the warranty expired. The A/C has been putting off a nasty urine smell for 20k miles that the service department conveniently couldn't smell. It is also hissing loudly. The left front brake/suspension is making clunking noises (again, service department couldn't "hear" it). Transmission is rough. No hill-assist. We're trading it in ASAP for a BMW X5. We are done with American cars.
Purchased a used (28k miles) 2011 Acadia in April 2012. Test drove and was tempted to buy a Toyota Highlander or VW Touareg but loved the body style and features of the Acadia.
DVD player broke after a week of owning it. Fortunately it was just barely covered under warranty.
A couple months later, at 300 miles past warranty the back hatch broke (wouldn't open manually or remotely). $600 to fix.
May 2013, a year after buying the vehicle we're on our 2nd time fixing the air conditioning (approx $1000/time), and there's an oil drip.
No other SUV in its class offers all of what we were looking for: a 3rd row, with captains chairs, and a reasonable amount of space behind the 3rd row when it's up, to haul a stroller or load groceries.
Love this vehicle.
It is quiet, smooth and comfortable for all passengers.
You get the perks of a sporty sleek look without the rough truck ride while preserving the practicality of a large SUV or truck space and utility.
The heated bucket seats and remote start for warm ups are a definite plus.
The sound system is not too shabby either.
What this vehicle is missing for its class is a heated steer and better gas mileage.
