  Thought I had a good car. - 2011 GMC Terrain
  By Tracy - November 16 - 7:29 am

  Bought this used 3 months ago. Had a problem with a timing belt and something else a month ago and it was repaired under warranty. My warranty went out last week. Yesterday, my check engine light came on so I had Onstar run a diagnostic check and they said it had something to do with the car not starting and I need to get it fixed within 7 days. This morning, I had to turn the heat up to 78 to feel any kind of warm air. Last week 75 was too hot. Also, mpg is not what they claim and that was one of the main reasons I purchased this vehicle. Very disappointed!

  The V6 is the way to go. - 2011 GMC Terrain
  By fionafirst - March 19 - 12:08 am

  The Terrain I own has a V6, not the I-4. (Not sure why Edmunds doesnt list that as an option) I bought this car used with 60k miles on it because I got a good deal on it and wanted a car with AWD. I recently took my car from Indianapolis to Destine Florida and have realized some good and bad things. The engine is beautiful. Peddle down and the power comes out. Aceleration in 2nd gear while merging is lusty, and passing power is plentiful. That being said, the car still feels heavy and any less power would not be adequate. The steering wheel is comfortable, the audio system is plenty loud and the power seats hold my big American butt pretty well. All in all, I would buy it again.

  A Lot of Issues and Problems - 2011 GMC Terrain
  By cockermom - September 12 - 7:23 am

  We purchased a 2011 GMC Terrain SLE2 Automatic with a 4 cylinder engine. The engine is so small that this poor vehicle has terrible pick-up. Its dangerous to try and pass on the highway or pick up speed when merging because the pick up is so bad. Another major issue we have is that the engine seems to be hesitating or fluttering or it is stalling at low throttle which is extremely dangerous when driving period let alone driving up a hill. This problem warrants a recall. The doors are so lightweight that they will slam on you when opening/closing which is dangerous to passengers. This needs to be sorted by GMC as its dangerous. Passenger airbag light doesnt work. Poor gas mileage.

  Using Oil - 2011 GMC Terrain
  By graygrandma - September 2 - 9:05 pm

  I agree with all the disappointing remarks regarding gas mileage. I dont care if its the EPA or GMC - the public deserves the truth! My big worry now is that its using oil. My car was showing 50+% life left before my oil change. The engine was making a loud noise and I took it to the dealer to find I had no oil showing on the dip stick. The check engine light NEVER came on! Since then my husband has consistantly checked the oil level and we have to keep adding oil in between oil changes. I have never had to do that with my vehicles. Anyone else using oil?

  I got suckered into buying this based on Gas Mileage - 2011 GMC Terrain
  By vlazo - June 7 - 10:57 am

  Im very disappointed in my purchase of the 2011 GMC Terrian. When i bought this i was told like most about the amazing gas milegae that ranged from 23-32 mpg so i made the decision that for my first new car i would go with the 2.4L 4 cylinder FWD model to maximaze fuel econonmy. I have never seen more then 23.6 miles per gallon and that was after putting in premium gasoline(which is not called for i was just doing anything i could to get better gas mileage) and highway driving...whats wrong with this picture??? I average 21.9 mgh normally & my car has 21,000 miles so it doesnt need to b broke in like i was told by my dealer.

  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.

  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??

  Stay away from the I-4 2.4L engine!!! - 2011 GMC Terrain
  By wrusprod - November 5 - 4:21 pm

  There is a major issue with the 2011 I-4 engine.. with a rattling startup noise. Any GM vehicle with this engine has the problem, Chevy Equinox, Buick Regal..etc... intermittant Rattling noise on startup, stalling, engine codes, poor MPG, bucking transmission.. and GM has been playing guinea pigs with all the owners who keep taking back to the dealer for repair of the rattling noise..almost a year with this issue and still no solution...STAY AWAY FROM THE I-4!

  Where is the gas mileage? - 2011 GMC Terrain
  By jess736 - September 19 - 6:53 pm

  We purchased a 4 cyl Terrain earlier this year. We like the vehicle overall but are very disappointed with the 21.6 MPG average over the first 9000 miles of driving. Most of the driving is on the freeway. Even on a long trip the best ever on a tank of gas was 23.5mpg. The main reason for us selecting the Terrain over other SUVs was the advertised mileage. We really feel we were scammed. I know that the EPA mileage to be questionable but to exaggerate the numbers by over 33% is almost criminal. Of course the salesman sold us on the 32 MPG but after talking to the service techs they tell me that there is no way that this vehicle can get more that 23 to 24 MPG. Of course now that we ha
