Replying to: manufan1 (Aug 25, 2008 9:36 am) My 2008 Acadia AWD MPG has been consistently around 13mpg with city/hwy combo driving (1 yr, 17K miles). I'm very disappointed, as I expected to get considerably better mileage than our '04 Trailblazer EXT (larger vehicle), which has a high-end V8 and it gets 15mpg! The highway driving is very disappointing. If there are hills with any sigificant grades I have to use the manual shift (5th most of the time, sometimes 4th gear) to maintain a constant speed. Speed drops as much as 4mph if left in "Drive". Highway driving yields 19-20mpg, usually 74mph in a 70 speed zone. Yesterday after about 2 hrs on the highway the DING DING DING "STABILITRAK TRACTION CONTROL OFF" message woke up and cried to me again. This occurs occasionally, for no apparent reason. OnStar always says "your stabilitrack and traction control system are disabled, and your ABS system is not functional, but it is ok to drive, you should have it serviced in the next 7 days". Service people can never find any codes or anything wrong. Regarding poor MPG, Dealer says the computer may be calculating it wrong, and also use premium. I used premium fule for several tanks and found no difference in performance or mileage so I quit buying it. I've given up for now -- it's a gas guzzling SUV and if I want to change that, I'll need to buy a different vehicle. All that said, the pushbutton liftgate is pretty snazzy. |

I'm wondering if anyone has had the problem I have had with my 07 Acadia. I got mine in Feb 07. I have had lots of the problems that others have had like the leaking (brought back twice for that), had a transmission leak, losing the talking on the movies but not the background noise on the entertainment system, but has anyone been driving in the rain and have lost control of the steering? It has happened a lot with mine. It gets tight like you lost your power steering then in the next second it comes back. It rots if it happens when your trying to turn into a sidestreet with lots of oncoming traffic and you're trying to quickly turn. Mine also got hit on the second door of the driver's side. Someone went through a stop sign and I tried to avoid it but got hit anyway. I was off road a little in sand and it started fishtailing back onto the road. My husband saw the whole thing happen in his rearview mirror (he was in front of me) and he said he'd buy another one in a heartbeat due to how it handled. He said if I was in my old Caravan we would have rolled it. Me and my three little kids inside. So mine has been in the shop quite a bit. Since they had to blend the whole side of my car just to repaint the door, the paint never looks the same. It is not good. I own the Carbon black. Funny my husband is a mechanic but we bought the warranty 8 years bumper to bumper. Its a good thing because I have had a rent a car quite a few times. I do like the car though; its like my caravan was but without driving one. So if anyone has had the steering thing happen in the rain, can you let me know?

Sound like Standard AWD to me.

I am looking at a 2008 acadia. What is the "pop up" panel for on the dashboard? It is located in the center on top of the dashboard.

I’ve had my 08 Acadia since Jan. 2008. Had the software flash 6 weeks ago, and it did make a difference on the low end. No hesitation, and downshifts when you need it, but I took it on a long trip last weekend, and it would not shift into 6th gear. The only way is to set the cruise control to 110 kilometers (Canada) and accelerate to 120 km put shifter into manual and shift into 6th. Take your foot off the accelerator and let it coast to the set speed of 110 km. The RPM would then be consistent with the up shift to 6th speed. If I encountered a hill, it would shift back to 5th and stay there, the tack would show an increase in RPM. Alas fuel economy is disastrous. I'm taking it back to the dealer again but other then re flashing the software they don’t seem to have an answer. I love the feel of the Acadia, and have not had any other problems with it. Any body got any suggestions?
