#13 of 44 Terrain 3.0 V6 mileage reasonable
Apr 25, 2012 (5:16 am)
Two weeks into ownership of my 2010 SLE-2 3.0 with 25k miles, I have a fill-up confirmed average of 25.5MPG. This is all metropolitan driving; 30% city-suburban surface street, and 70% urban freeway.
I have found the best city mileage is obtained by accelerating to get to 40MPH reasonably quickly, so the trans locks. On the highway, economy drops off rapidly over 70MPH.
This vehicle is pretty heavy for the engine, so momentum is your friend on the road to decent fuel economy.
#14 of 44 Good news on Terrain mileage!

I continue to complain about the mileage on a 2011 Terrain - 4 cyl. The best I could get was a trip this summer - 2400 miles PHL to Minneapolis...55-70 mph - no city driving at all. I got 27.3 mpg.
GMC did a consumption test when I got home - drove 86 miles - city & highway and GUESS WHAT - they said it really does 38.88 mpg! Wasn't that a great test? I guess someone has been siphoning gas out of my tank for the miles that I have driven since I can't get close to 32 mpg!
Wish I had never seen this vehicle - but now am stuck with it! Guess I need a locking gas cap!!!

I am a Terrain owner and enjoy my vehicle. Until this purchase, I have always driven a Ford product and was looking to improve my fuel mileage when the Terrain was introduced. I do own the 4 cyl. vehicle and I did purchased it mostly for the MPG, but I am also impressed by the interior space and other basic features. I have had no problem with the crossover and enjoy driving it very much. To those that have had difficulty obtaining the maximum MPG...try driving with the "ECO" on at all times. It did take a little getting use to, but I have adjusted. I always average at least 30 mpg on the highway and close to the max in city. To those that are comparing their Terrain to a hybrid of some sort...you are not comparing apples to apples and my guess is that you paid quite a bit more for your vehicle.
I am happy with my choice to purchase a Terrain

#17 of 44 Never Again Will I Buy A GMC After The Terrain
Nov 19, 2012 (3:08 pm)
I purchased this vehicle for the MPG, and the MPG ONLY. It is a 2011 with 20,000 miles on it. I traded a 2009 GMC Sierra 1500 Z71 Crew Cab due to relocation, and my commute changing from 1 mile to 100 miles a day. In retrospect, I could have kept the giant gas guzzler I loved as it only got 2 MPG less than this miserable excuse for a fuel efficient vehicle. The only reason I purchased this vehicle was due to the 32 mpg fallacy that was printed on the window sticker. My daily commute is 98% 4 lane highway with a 65 mph speed limit, and I average 23.2 mpg. I have driven this vehicle for an uninterrupted 35 miles on a flat, Mississippi delta highway, with the cruise set to 55, and the air off in 85 degree weather, and could not touch 30 MPG, much less the 32 MPG advertised.
The worst part in all of this is that now, the trade value is next to nothing due to the current incentives placed on the vehicle. As no one in their right mind will buy this vehicle, GM has placed incentives on it that practically give it away; thus, making us practically have to give them away to get rid of them.
I can honestly say, after having this vehicle, I will never buy another GMC product again (to emphasize the significance of my displeasure, 5 of my last 8 vehicles in the last 11 years have been GM products.) GM, you either need to pull this vehicle and do some serious R&D, or brace yourselves to lose many more loyal customers.

Yes - it is a piece of crap. The dealer did fuel consumption test on my 2011 terrain and had the nerve to tell me that it really did 38.9 mpg on their test of my vehicle! I too have had many GM products in the 47 years I have been driving - and no, there will never be another GM product. We are paying twice - considering the government bailout - what a fiasco!

I assume you have the 4 cyl, I have seen elsewhere some get close to the EPA numbers on sticker, and of course others don't. On my 6 cyl it doesn't shift into highest gear until 56 MPH or so and I usually set cruise to 57-60 MPH for better numbers. A couple times when on a trip I have noticed MPG isn't what I would expect and after checking found it was inadvertently left in re-circ or defrost mode for HVAC, correcting that made for better numbers ( I also for some reason don't like the auto setting for HVAC)

Good morning amburkes,
We're sorry to hear that you are not satisfied with the fuel economy you are getting with your Terrain.
The fuel economy estimates are based on results of tests required by the U.S. Environmental Protection Agency (EPA). These tests are used to certify that vehicles meet the federal emissions and fuel economy standards. Manufacturers test pre-production prototypes of the new vehicle models and submit the test results to EPA. EPA re-tests about 10% of vehicle models to confirm the manufacturer's results. The vehicles are driven by a professional driver under controlled laboratory conditions, on an instrument similar to a treadmill. These procedures ensure that each vehicle is tested under identical conditions; therefore, the results can be compared with confidence.
The EPA's fuel economy estimates are designed to allow consumers to comparison shop. Your fuel economy will almost certainly vary from EPA's fuel economy rating. This is based on a number of factors, such as weather, road conditions, driving and maintenance habits, and the use of air conditioning. For more information on how your fuel economy can vary, or tips to improve your fuel economy, please visit "Your MPG Will Still Vary" and "Gas Mileage Tips" on www.fueleconomy.gov.

Like most Terrain Drivers I cannot get any where near the mileage displayed on the car and advertised in all the media ads. Simply put, this vehicle does not get 32 MPG on the highway. I have owned numerous vehicles, mostly GM and have ALWAYS achieved the mileage posted on the sticker and more. So what's the dealio GM? You know you have a problem. Why can't you admit it take it on the chops like Hyundai and reimburse owners of the vehicle and the Chevy Equinox? Even the dealers I spoke to warned my not to expect the mileage on the sticker. Based on my past history I thought they were fools. No more, it was me that was fooled. The service people say the same thing. They have no idea why the vehicle does not get the mileage as advertised.
It probably has something to do with government buyout. The old stand on your own two feet GM built vehicles that performed. My 2012 SLE FWD 4 Cyl is very disappointing. I have seen it get up to 28 but that's about the best I can expect.

I agree - however, GM did a consumption test on my 2011 FWD 4 cyl and guess what? The dealer said it does 38.8 mpg! I think you need to bring to Quakertown, PA, Star GMC - they obviously know something that you or I do not know. I would like to know where the gas is going - I guess it is leaking out somewhere since I can only get 27.5 mpg under the BEST of conditions.
By the way, I never get a response from GMC on this website; guess they don't like me making fun of their poor gas mileage. I love my Toyota Camry Hybrid - 95,000 miles and it still gets 38 - 41 mpg! Too bad we bought the GMC in a weak moment - now we are STUCK with it. Nobody wants them!
The best part - GMC believed the dealer's number! Isn't that interesting!
