Vehicle: 2008 GMC Acadia SLE-1 4dr SUV (3.6L 6cyl 6A)

I bought my 2008 GMC Acadia with 25,000 miles on it. Loved the quiet ride and the space...then the bottom fell out. Water pump at 42000 miles at $564 (later paid for by GMC...amazing). 47000 new master cylinder - $670 68000 new transmission - $3400 Now my serivce manager says the thing to watch for now is the heating and A/C. None of this was under warranty because it says it was a 2008 but came off the line in 2007 so no warranty. After reading all of the following post....When is GMC going to step up? Is there any leverage we have? No more GMC for me.

Time for another acadia- maybe

Vehicle: 2008 GMC Acadia SLE-1 4dr SUV (3.6L 6cyl 6A)

I love my Acadia however I must say that this Vehicle has had more problems than any other vehicle I have ever owned. Headlight $500 New Transmission $3,500 New Odometer $500 sqeeking noise in dashboard. We also Own 2 Buick Enclaves. Just bought my wife a 2012 Buick in March. I'm waiting for the 2013 GMC Acadia's to come out but I worried about any problems with new models and the fact that my current SUV cost soooooo much in repairs. What to do????? I would love to hear back from GMC customer relations.

Worst vehicle ever!

Vehicle: 2008 GMC Acadia SLE-1 4dr SUV (3.6L 6cyl 6A)

Purchased to replace a mini van. Huge mistake, has been in the shop several times, about once every 6 weeks for repairs. Biggest issue is with the AirBags, have had to have it in to service these 7, yes 7 times. GM says that they cannot and will not give a guarantee that the airbags work, if the lights not on assume that it works. Apparently safety not an issue with GM. We have had leaking windows, pw motor replaced, steering column squeaks, wipers don't work, fuel economy is terrible, brake line clips that have come off, lunges when you accelerate up a hill, the list goes on and on. Worst vehicle we have ever had. Should have let GM go under!

Interior is going wrong!

Vehicle: 2008 GMC Acadia SLE-1 4dr SUV (3.6L 6cyl 6A)

I've had the acadia over 2 years. I love it! Well recently I've had some problems with the interior. The hydraulic arms to the back door have also gone bad. The larger seat in the middle passenger row won't move. The seat belts in the back are not comfortable (latches), they don't give at all. Good if you are tiny and can fit between them. I'm just disappointed in the problems going wrong right now. Sunglass compartment on dash also sticks. Nothing mechanical (cross your fingers). Wish the tires were a normal size so they didn't cost so much to replace! Love the car though!

What's New for 2008

For the 2008 GMC Acadia, eight-passenger seating and satellite radio become standard on the base SLE-1 model, while a rearview camera and a second-row console become available on upper trim levels.


In the past few years, sales of traditional SUVs and minivans have been dropping as consumers gravitate toward crossover SUVs. And it makes sense. Why buy a 6,000-pound truck-based SUV that can pull a tank and tackle the Baja 1,000 when all you really need is something to shuttle the kids around and deal with wintertime driving conditions? With the 2008 GMC Acadia crossover SUV, a more reasonable alternative is offered, and it just happens to be the best all-around family vehicle GMC sells.

The Acadia was introduced last year and is closely related to its corporate siblings, the Saturn Outlook and Buick Enclave. Like other popular crossovers, the Acadia has a unibody structure for better handling, interior packaging and crashworthiness. It also has a V6 engine and available all-wheel drive. Helping the Acadia stand out, however, is its size. We consider it to be a large crossover, and indeed, it's about the same size as a Yukon. As such, the Acadia can seat up to eight people and its third-row seat can accommodate adults with ease. Folding those seats down also provides a serious amount of cargo space.

Everything factored in, the 2008 GMC Acadia has a lot in its favor. It's even proven to be the best-selling model of the Acadia/Enclave/Outlook group thus far, thanks to its just-right approach to style and design. We give it a strong recommendation, especially for buyers with large families. But if you don't find it to your liking, there are other models to consider, including the recently introduced Mazda CX-9, redesigned Toyota Highlander and well-regarded Honda Pilot.

Body Styles, Trim Levels, and Options

A full-size crossover SUV, the 2008 GMC Acadia is offered in three trims: base SLE-1 and uplevel SLT-1 and SLT-2. The SLE comes with 18-inch alloy wheels, eight-passenger seating, front and rear air-conditioning, full power accessories, cruise control, OnStar telematics and a six-speaker CD/MP3 stereo system with satellite radio.

The SLT-1 package adds heated mirrors with integral turn signals, leather seating with heated/power front seats, second-row captain's chairs, triple-zone automatic climate control and a Bose 10-speaker audio system with steering-wheel audio controls and six-disc CD changer. The line-topping SLT-2 adds remote vehicle starting, rear park assist, a power rear liftgate, power lumbar supports for the front seats, a 115-volt power outlet and a rear cargo shade.

Both SLT models can also be had with eight-passenger seating, and many of the SLT-2's features are available on lesser models, too. Option highlights include a DVD entertainment system, a rearview camera, a second-row console, a two-panel sunroof, 19-inch wheels, a head-up windshield instrument display, a navigation system, Dolby 5.1 surround sound and third-row audio controls.

Powertrains and Performance

The 2008 GMC Acadia can be had with either front- or all-wheel drive. A 3.6-liter V6 makes 275 horsepower and 251 pound-feet of torque spread over a broad rpm range. The front-drive 2008 Acadia rates 16 mpg city/24 mpg highway, and the AWD version stands at 16/22. Towing capacity, at 4,500 pounds properly equipped, should be enough for most folks.

Though GMC has built its image around tough trucks, the all-wheel-drive Acadia is geared more for foul-weather driving than boulder-bashing. The AWD system is active and requires no driver intervention. The system automatically varies the torque split from 90 percent front/10 percent rear to 35/65, respectively, as available traction dictates.


Standard safety features are generous and include antilock disc brakes, stability control, front-seat side airbags, full-length side-curtain airbags and the OnStar communications system. National Highway Traffic Safety Administration crash test scores are impressive, with the Acadia scoring five stars (out of five) in all frontal- and side-impact tests.

Interior Design and Special Features

Thanks to its space-efficient design, the GMC Acadia provides sedanlike comfort for all passengers. A third-row seat is standard, and one may choose between seven- and eight-passenger configurations. The 60/40-split second-row bench allows eight to ride, while second-row captain's chairs reduce capacity to seven. Additionally, access to that third row is eased by wide rear doors and a sliding second-row seat. Although taller folks in the way back may wish for more thigh support, the accommodations back there are much better than most crossovers or traditional SUVs. Cargo capacity is abundant, with nearly 117 cubic feet available with all seats down and a still very respectable 19 cubic feet behind the third-row seat.

Driving Impressions

While the 2008 GMC Acadia doesn't fall anywhere near the fun-to-drive camp, it's easy and pleasant to drive, especially considering the vehicle's size and 4,700-pound curb weight. Those planning on towing a trailer will want to consider the SLT versions that feature variable-effort power steering to make quick work of maneuvering. On the road, we've found that the optional 19-inch wheels increase the crossover's bling factor, but they also compromise the Acadia's otherwise comfortable ride quality, turning it into a somewhat jarring experience that many target buyers won't enjoy. Our only other complaint regards the programming of the six-speed automatic, as downshifts can be a bit lethargic unless prodded by a sharp throttle boot.
