  Gas Mileage Tanks - 2011 GMC Terrain
  By kristarc - September 27 - 7:49 am

  My husband and I researched many vehicles before deciding the Terrain was the best SUV for our needs without sucking our wallet dry. I have owned the Terrain for a month now. My daily driving is mostly highway and I am only getting about 23 miles a gallon. I didnt expect to get 32 but I did expect more than this. The vehicle also shifts hard and jerky. I think GMC needs to review their claims of great gas mileage before many others are misled. They also owe myself and thousands of other people gas cards!!

  First GMC - 2011 GMC Terrain
  By bhallett21 - July 20 - 11:17 am

  Ive only had my Terrain for 2 weeks but so far it has exceeded my expectations. Gas mileage has been between 24-25 mpg combined driving with eco on, fine with me for the size of the vehicle. I bought a 4 cyl because let’s face it you dont really need all the power of a V-6 unless you tow things. The inside of the Terrain is excellent, I "upgraded" to the SLE2 because I wanted some of the features. Its drives like a dream, I just got out of a lease on a Nissan Altima Coupe and the suspension on the Terrain absorbs bumps much better. Its no sports car but I didnt expect it to be. Anyway I think it fits its job and place in the market perfectly.

  love our terrain - 2011 GMC Terrain
  By tombeaversr - June 29 - 10:02 pm

  We bought our terrain in Feb. 2011 and now have over 6700 miles on it. avg. mpg is 24.8 to 29.5 local and 29 to 33.2 hwy. The seats are good butnot as comfortable as the 1999 buick lesable that we had but the terrain does handle much better. The 4 cyl is not a dog if you wind it up but you can definitly tell that the old girl weighs a lot. In stop and go traffic it is real easy to get mpg down to 22. With cruise set at 65-70 on reasonably flat ground we get 29.8-33.2. have not got use to unlock button being in middle of dash. No problems yet. Buick lasted 233,000 miles. Hope this GMC does too.

  15k later - 2011 GMC Terrain
  By tim4711 - June 25 - 11:52 pm

  2010 SLE 1 Terrain. I couldnt be happier. Unlike some other unlucky owners my Terrain has performed exactly to spec. My mileage(If I drive under 65mph) hovers right around 27mpg. If I drive over 70 then I get around 24mpg. Around town I am getting 18-20 Mpg. The only issue I have had is my lumbar bladder needed to be replaced. Of course this was a typical GM design error meaning that the replacement was much better. All in all I have no complaints. Its a nice 4cyl. car. For those of you that dont know about the ecotech engine. Try cruising at about 75. I think you might be surprised at how the car feels:)

  Give the gas mileage some time! - 2011 GMC Terrain
  By mab13 - June 20 - 8:11 am

  I have heard numerous complaints about the gas mileage. I will say, I was one of those people complaining until I took a recent trip and drove nearly 1,500 miles. At this point, I have 6,000 total miles on my Terrain and I can finally say, I AM getting the gas mileage advertised. Until my trip, I was lucky to get 24-26. I am now fairly steady at 29-31. Drove into work this morning (a 1-hour commute) at 30.6 the entire way. I was told to give it time but I was a nay sayer. Im happy to say, it was true. After a good "break-in" period, my Terrain is getting gas mileage. Outside of that, I have no issues whatsoever with this vehicle. Its rugged in appearance and drives wonderfully!

  My Gas Mileage Experience - 2011 GMC Terrain
  By prbart1 - June 20 - 12:35 am

  Since I bought my Terrain, I have put 6,469 miles on it, doing mainly "suburban" driving in the Chicago area (stop signs or traffic lights about every mile, on average). In this type of driving (ECO mode on), I now average between 24 & 25 mpg. When the car was new, the mileage was not this high, but it increased as the engine got broken in. Ive also take two road trips in this vehicle (ECO mode off): the first was about 300 miles when the engine was still in "break-in" mode & I got 28.0 mpg. The second trip was about 950 miles, after the "break-in" period (Interstate at a steady 70 mph), & I got 29.8 mpg. I calculate my mpg precisely, so this data is as accurate as I can make it.

  EPA Mileage is accurate --- under right conditions - 2011 GMC Terrain
  By new_terrain - June 7 - 4:47 pm

  I live in a semi rural area where its possible to drive with cruise control set at 50 - 55 MPH. Under these conditions, its entirely possible to get the rated 32 MPG. The EPA definition of "Highway" does not mean "expressway" or "interstate". The EPA test methodology is explained at: [HTML deleted] Note that the average speed on an EPA highway mileage test run is 48.3 MPH. Obviously this isnt representative of a morning commute on an urban expressway. However, the same method is used by the EPA for all vehicles. Even if your driving habits differ, the EPA numbers are still useful on a relative basis. PS I think its a great vehicle

  The EPA Lies!! - 2011 GMC Terrain
  By bluesky12 - May 30 - 1:42 pm

  Theres a lot I like about the 2011 GMC Terrain, but unfortunately gas mileage isnt one of those things. I drive a 4-cylinder and use ECO mode and my city MPG is about 21 and highway is no better than 25 MPG tops. Performance overall is adaquate at best. I sacrifice the performance of 6 cylinder to get the better gas mileage and that didnt happen. Now I get mediocre performance and mediocre gas mileage. I bought this vehicle because of the advertised 32 MGP. There is NO WAY on Gods green earth that I could ever get 32 MPG - not even close. The EPA absolutely lied!! If gas milegae is a high priority, dont buy this vehicle. I like a lot of the other features of this vehicle.

  Love It! - 2011 GMC Terrain
  By susan54935 - May 24 - 8:49 pm

  I bought the 4-cyl because of the promised 32 mpg. I did manage to get 28 mpg on a long trip across country with mostly highway driving. On a regular basis Im getting about 20 mpg. This was the only dissapointment thus far! I have nearly 10,000 miles and have absolutely no complaints! I love the exterior styling of this SUV. The interior is extremely comfortable! I would definitely buy another Terrain in the future - at this point anyway! I love it! We are empty nesters and the cargo space is just perfect for us! It is so easy and comfortable to drive!

  Headliner - 2011 GMC Terrain
  By sls12 - May 21 - 8:39 am

  I have had my 2011 Terrain for 8 months, the headliner came down in first 3 months, they tried to fix by placing in new magnets. This did not work, the headliner was down by the time I got home from the dealership. They then ordered a new complete headliner, installed this a month ago, and it is down again. This has taken 4 trips to have this worked on with another trip next week to start again. This is very frustrating and time consumming. Other than this, I do enjoy driving even though it is a little slow. If the headliner is not resolved this time I would never purchase another GMC product. Not worth the aggravation on a new car.
