I, along with 2 of my children and 2 co- workers, have a 2012 Terrain. NOT ONE OF US gets over 25 mpg - no matter where/how we drive...We all average between 23-25 mpg. PLEASE call GMC (1-800-462-8782 ext 4308 and tell Mark, AJ, or John if you or someone you know gets less mpg than expected. Gas mileage was THE factor for most of us choosing the Terrain, and it is NOT delivering! Thanks!

Your MPG seems about right both for what GM advertise MPG for the terrain and for all mid size SUVs. GM advertises 22 MPG for normal/ typical driving.

I know of no mid size SUV that does better mileage. Maybe you should downsize to a small sedan like a Volt, Civic or Prius if mileage is more important to you than the size of the vehicle.

In addition to the above quote, may I suggest a Malibu Eco or Cruze Eco. These two fine cars get better mileage than the Terrain.

Although 20+mpg with an SUV style vehicle doesn't sound too bad, I think I'll stick with my '94 Delta and '97 Bonneville, which both get better gas mileage than the Terrain. I was just in the States and got 32.3mpg with the Bonneville between Fort Knox and Kansas City. I put the A/C on the whole return trip and got 30.1mpg.

I realize this doesn't add much to the thread, but I just can't understand how people can subject themselves to tiny box cars, so-called 'large' (but more cramped interiors) SUVs, and pay the exhorbitant prices, fees, license, property taxes, and insurance for vehicles which get poorer gas mileage than something 10-15yrs (or more) older.

Good luck.

unfortunately suv'* are the "in thing". and it seems when car companies advertise good mileage its really good for a car in its class. so its good for a truck. but trucks get 20 or less

I average 26 MPG in my Equinox. We got 23MPG going down to Florida with fully loaded car, 4 people and roof carrier.

Vehicle Sticker fuel ratings are never what u get.
That is with a half a tank of fuel, stock tires, and one passenger with a tail wind LOL.
I wish I could get that kinda mileage!! My Lifted Libby SUV (sucks up volumes) of gas.
My last mainly highway trip I averaged 17mpg. With skids, rack etc it is 4900 lbs though.
My KJ was rated at 17 city 22 hwy. Reality..12 city...18 Hwy and I pay $6 per gallon here!

Aerodynamics and weight play a large role in fuel mileage. Cars outperform SUV always.
That is why I also have the Buick PA it does about 22 city and 36-41 hwy.
My jeep is used as occasional use, boat pull and severe winter/mountain use only.
Jeep consumes almost twice the amount of fuel over Buick in long runs. (yeiks)

you guys have the CRD liberty available? they only made it for a while but i saw one last week, which is uncommon here in this state. seems not very many buy any diesel anything but 3/4 trucks or larger. but i thought it would be cool and probably get mid 20'*, which would be good for me but i need to be able to haul 6500. they only rated the jeeps for 5k, though. my yukon gets like 15, never took it on highway, but i can haul what ever trailer i want

They sold quite a few CRD around here Justin. There are 3 for sale on CL here.
I think they were fairly reliable too once u got the bugs out of them.
Timing chains replacement at 100k miles a must.
Being a shorter wheel base they are not the best for towing. I have to keep my 4000lb boat pull at 55mph otherwise I get sway problems if I hit 60mph.
For that 6500 lbs trailering I would still recommend a PU or that Yukon is good!
Here is a quick read: Buying a Used Jeep Liberty CRD - Diesel Power Magazine

i had a gas liberty for a work vehicle for a while never towed anything with it, at that time i was just working in remote areas with bad access. it was nice except the mileage, fortunately i wasn't paying for gas. i had a jeep xj cherokee though for a long time and it wasn't good for towing either but not really what it was intended for with soft suspension and short wheelbase, mine was a toy though and something to drive in the winter. had to get rid of it because it wouldnt tow the camper we wanted, didnt want to sell it though
