  7 times in the shop first year - 2011 GMC Terrain
  By kathy75 - May 16 - 6:25 pm

  I thought I was exchanging a 9 year Murano that was needing its 5 transmission (which was still under warranty and was no longer reliable as something I could depend on, wrong! This 2011 terrain has been in the shop 7 times for a total of the same 3 problems. 4 times for cutting off and cutting out on me, the lift gate made loud noises when it got hot and finally after 5 times in the shop in which they told me unless it makes the notice when it is in here you will just have wait until breaks, well it did and came down on my head. The air stopped working last summer twice while it was in the high 90s you could turn it back on after about 20 minutes and it would work again.

  2011 GMC Terrain Poor Gas Mileage - 2011 GMC Terrain
  By longbow1 - March 26 - 10:07 am

  Purchased our 2011 GMC Terrain Feb 2011 and still waiting for 32 mpg. If I knew the mileage was going to suck Id purchase the V6 to give me better pick up, passing acceleration, and cruise control performance going up freeway hills. We love our Terrain except for the engine and mpg. The best mileage experienced on our trips to Utah and Arizona from California is 23.2. Currently in the city 21.2. Wheres the miles per gallon as advertised. Just saw a 2013 Terrain commercial on TV last night (3/25/12) boasting 32 mpg. Both my wife and I laughed!

  Bad gas mileage - 2011 GMC Terrain
  By elvis711 - March 5 - 2:04 pm

  Just like everyone else- 22-25 MPG. Also, it does a hard shift all the time, and often when pressing on the gas, it hesitates, as though it had to think if it was the brake or the gas , it makes you very angry when driving. Terrible experience. One good thing is the storage. Too bad we cannot afford to road trip with the crap mileage.

  A BIG MISTAKE - 2011 GMC Terrain
  By sgthaight - February 8 - 6:12 pm

  Leased this vehicle in 4 cylinder, was promised 26/32 mpg city/highway. A BLATANT LIE FROM GMC! Veh gets 14-16 in town and cant get over 21 on the highway. GMC was contacted and set up a service check at the dealer. They came up with every phony excuse you could think of. Too much weight in the veh (which is empty) to the mileage gauge must be reset every time ( even though the On-Star app says the lifetiMe average mileage of both city/highway is 17). Avoid this car at all expense, it has no power and the mileage SUCKS. GMC will try to blame you for the crummy mileage if you complain. Searching for a lawyer to take on the big GMC Corp. Buy American, but not this American vehicle.

  Really Disappointed in my Terrain... - 2011 GMC Terrain
  By sllmd0202 - February 4 - 7:26 pm

  My husband and I bought the 2011 GMC Terrain about a year ago. In the last six months, its been in the shop twice now. The first time was for an electrical issue...a terminal in the back of the car had corroded causing it to pull power on the ignition and drain the battery. It took the dealership almost two weeks to diagnose and fix. Then, six months later it would start but anytime you gave it gas, it would cut off. Still in the shop after two weeks with no answer. As both my husband and I being prior Toyota owners, I definitely regret buying this car. I should have kept with Toyota. Just an overall bad experience.

  Gas Mileage - 2011 GMC Terrain
  By bwall2 - January 28 - 5:13 pm

  This is my 3rd posting about the horrible gas mileage of this vehicle. I would love a class action suit for performance....I bought it for the 32 mpg expecting to receive at least 27-28 mpg. How disgusting! I like driving my Camry Hybrid - 38-41 mpg - and 76,000 miles on it. No more GM products for me!

  Milky white fluid 1st. Rusty brown 2nd. - 2011 GMC Terrain
  By gunkedmotors - January 12 - 10:42 pm

  We have a 2011 GMC Terrain SLT, and this is the second time it has been in the shop. Milky white fluid boiled out of the water reservoir the first time. The dealer said the tubes that ran inside the radiator busted causing the white milky substance. The radiator was replaced and did numerous wash cycles for 3 weeks. We got the car back and 2 days later the radiator busted in my driveway and rusty brown fluid spewed out of the radiator. The check engine light has yet to come on. The dealer said it was the same problem. I asked if they did compression check for blown head gasket, and never got an answer. Is it a bad radiator or to much compression in the radiator. January 22, 2012 is year.

  False MPG: Just lost fifteen hundred bucks! - 2011 GMC Terrain
  By retiredpilot1 - January 9 - 11:16 pm

  I have had my 2011 Terrain for 15 months, 23,000 miles. This car cost me an extra $1500 last year in gas because the actual mileage (17/22) is NOT EVEN CLOSE to claimed. I am a retired airline pilot and mechanical engineer, I know how to glide thru air. It really peeves me that we allow such false and misleading advertising, whatever happened to good old honesty? See you at the class action claim hearing!

  What can I do about gas mileage? - 2011 GMC Terrain
  By mab13 - December 30 - 11:09 am

  I will start by saying I am very careful when driving my vehicles to make sure I am getting the best gas mileage. I drive very appropriately. My gas mileage sucks. I traded in a Torrent for this and my Torrent got just about the same mileage, yet I paid a lot more for my Terrain! Now, I am stuck with a long commute to work and horribly gas mileage. They claim 32 hwy, I never expected 32, but Im lucky to get 24-25, and again, I DO drive properly. Do I have any recourse for this? Im pissing away money driving 2 hours per day thinking this care would save me money!

  very disapointed - 2011 GMC Terrain
  By lapitino - December 21 - 6:06 pm

  I am very unhappy with my 2011 model. It is less than one year old and only has 15,000 miles on it. In the last two weeks it has been in for repair 3 different times. It has gone in for multiple issues, 2 out of 3 are yet to be fixed. I have been in a rental car for a total of 12 days now. My fear is that this is a sign of things to come. I plan to ask for a replacement vehicle or I will absolutely be contacting the Connecticut Department of Consumer Protection. Did I mention the gas mileage it NOT what was advertised??
