#217 of 251 Dodged the MPG Bullet! by lesliechow

Thank you to everyone who has taken the time to post. I was just about to purchase a new Acadia (just got back from the dealership). After reading page after page of MPG comments - I've decided not to purchase the gas guzzler Acadia. GM should be more truthful. This MPG info needs broader exposure. I'm going to help others by posting to Facebook

Good choice ! The Acadia is worse in mpg than almost any other full size and mid size suv is .. I would recommend a Toyota product .

For starters, I was reading how many individuals are having issues with their Acadia's. If I had come across this forum when I was in the market for a vehicle, I would probably be driving a minivan due to my needs. I must say that I have been very lucky with the one I got (knocking heavy on wood here) for I have yet to experience all the hardships that many owners have already endured. I have a 2010 Acadia SLT, FWD and yes while I think the MPG kinda sucks it is not even close to some complains here. I am getting above average MPG but it is probably due to the way I drive the vehicle (wife is a different story, she is a lead freak). It is odd that I had the very same bad experiences with brand new Acuras as many current Acadia owners (yes and the Acura dealerships did me wrong to the point that I do not want to purchase another Acura in the future). Hence, I expanded my horizons and bought the Acadia. I hope to dodge the barrage of problems everybody else is having, 'cause to tell you the truth if it happens one more time I think I will have to get me a horse.

I recently came back from a 2k mile trip with my Uplander minivan. It has a 3.9 liter 240 HP V6 engine and 4 speed automatic. I averaged 23 MPG (i.e. includes mostly highway but with some local, short distance driving) with the van fully loaded. Seems like the old-tech V6 and 4 speed auto beats GM's new tech, at least with respect to fuel efficiency.

Just made an 800 mile trip from Michigan to Maine, mostly on cruise control at 60 to 65mph.
Mileage for the trip - 20.87mpg.
My window sticker says "Most drivers will achieve between 21 and 29 mpg.
I would LOVE to know how GM figures ANYONE is going to get 29mpg when I can't even get 21 with a 2WD!

For measure MPG more accurate, I filled up my gas tank then reset the trip odometer to zero. On my next gas fill-up, I wrote down how many miles I drove and how many gallons that I have just filled-up. Do the math with my cellphone calculator, take total miles divided by total gallons. This should be a right MPG rating. I did it with a long trip from Dallas to Houston with driving 70-75 mph. It was 22 mpg. On the way back, I drove a little slower from 65-70 mph, it was 25 mpg. For a better mpg, ones should maintain speed at 65 mph. When I compared with the information center dashboard of my Acadia, it shown 1 mpg less difference. Note that this is my highway calculation. I have yet measured in city. But I guess it is about 16 mpg since my average combination hw/city is 18-19 mpg. Other factor, I keep changing my oil at 4000 miles or 4 months whichever comes first. Clean the throttle body chamber every year. I use KN air filter and clean it every 6 months.

My 2008 Acadia SLE AWD with 30,000 miles only gets 4.9 mpg. What could cause this?

Have you checked the following on your vehicle already:
*Are your tires fully inflated?
*Is your air filter dirty?
*Is the oil of the proper viscosity?
*Are the spark plugs running efficiently?
 
These would be good places to look (you may already have done so); http://fueleconomy.gov/ also has great resources on how to improve fuel economy.
 
If this is something you were thinking about having checked out, please let us know if you decide to work with one of our dealerships as we're available to help through the process. We can be reached at socialmediagm.com (please include the last 8 digits of your VIN).
 
Best,

#226 of 251 2010 GMC Acadia 5.0 MPG average by tamara1802

I also brought my 2010 Acadia with 24,000 miles into the dealership today for a gas mileage issue. I am getting on average 5 miles to the gallon.
 
In January of 2011, the dealership did a transmission adjustment on my car that lowered my gas mileage by about 2 MPGs. While unhappy with this, my husband and I werent given another option. Since then the gas mileage has continued to lower.
 
Today, the dealership called and told me that the problem is simply I need to fill my tank up all the way and they dont recall doing any transmission adjustment on my car that would have affected gas mileage. They say they only did an "ECM" adjustment that would havent affected gas mileage. My husband and I were both present for the conversation in 2011, it was a big deal to us & we know the name of who we spoke to.
 
I am very unhappy with my Acadia and wouldnt recommend it to anyone. This isnt the only service issue I have had and taking it to the dealership is a hassle. It just isnt right that I will be forced to trade it in and lose money on a vehicle that I had planned to keep long term.
