  Good SUV--but--- - 2010 GMC Terrain
  By dcunitednut - August 28 - 4:03 pm

  I purchased my 2010 Terrain after evaluating a number of SUVs. I almost bought the Chevy Equinox but fell in love with the Terrain during the test drive. For the last 4 years the vehicle has been virtually trouble free and very dependable. However--right at 56K miles there was a catastrophic failure of the transmission which required a total rebuild. The Wave Plate, along with a number of other components, basically flew apart. On the positive front the dealership took very good care of me and gave me an excellent loaner vehicle and kept me informed. I had no out of pocket expense because it was covered by the drive train warranty.

  Wow, 1 day to the 3 year anniversary and engine light goes on. Code P0172. Fuel pump low pressure, fuel line crack and gas leaking into engine and oil... Oil 3 quarts low... GM warranty is supplying a New Engine! Just wow, I get a new engine, but what other trouble will this cause? Transimission problem? I hope not.. I hope it gets fixed 100%. Wish us luck.

  Bad First Car Experience - 2010 GMC Terrain
  By elizabeth87 - January 14 - 12:02 pm

  I bought my Terrain as a brand new model when it first came in at our local dealership in October, 2010. I have had nothing but problems with this vehicle. I have had to have my transmission re-calibrated 3 or more times now, I have about 1 to 1-1/2 quarts of oil drain out when an oil change is done every 3,000 miles.. I have had a camshaft actuator replaced, many different solenoids replaced, a cracked timing chain tensioner bracket replaced, my exhaust manifold gasket was leaking, a wheel bearing go out at about 20,000-30,000 miles, & have had a carbon clean out done 3 times in the last 6 months because its causing my car to shut off. I am currently looking to trade this in.

  V6 with AWD - 2010 GMC Terrain
  By JR - November 13 - 2:00 am

  Bought this vehicle with 4800 miles on it, now has 10500 and have loved it. Get 17-19 mpg in the city and 24 mpg on the highway. The transmission does have a "different" shifting to it but not a big deal.Have gotten several compliments about the styling and such. GMC could do some improvements to it but that would be nit-picking on my part. Had a 2002 Hyundai Santa Fe (for 8 years) and love the Terrain much more.

  Mileage issues - 2010 GMC Terrain
  By eileen - October 17 - 2:00 am

  I really like my four cylinder, 2010 Gmc Terrain, but it is getting nowhere near the listed mileage of 6.1 L per 100 km.

  Not for the Interstate Hwys - 2010 GMC Terrain
  By Not Hills - October 12 - 2:00 am

  The 4 cyl Terrain lacks power to use cruise control on Interstate Hwys if there are any hills at all. The Tach will goes from 2000 to 4000 and roar like hell on any little rise. In town and on flat land highways it performs fine. It is comfortable for driving and looks fine. I suggest, however, if you can afford the extra dollars, buy the 6 cyl.

  32 Hwy. EPA is a big lie. - 2010 GMC Terrain
  By Ron Bowman - September 14 - 2:00 am

  The number one reason for buying the 4 cyl. Terrain was the 32 MPG Hwy. advertised. This could not be more wrong. We recently drove over 2400 miles which most was interstate highway and averaged only about 25 MPG. We are senior citizens and this was mostly on cruise control at less that the listed highway speed. We are very disgusted with this poor hwy. mileage and will certainly not recommend this vehicle to friends and family.We could have bought another Town and Country which is a 6 cyl. and we averaged over 25 MPG on the last one we owned prior to the Terrain.

  Lemon - 2010 GMC Terrain
  By grajcar42 - July 30 - 4:53 pm

  Purchased mt 2010 terrain on June 11. It was a pleasure to drive. Coming home from vacation on July 3, we were in stop/go traffic on I-95. At a traffic light the car refused to go forward. After pushing the accelerator in moved very slowly and then would pick up speed. We made it home. The car had 1600 miles on it. Dealer cleaned solenoids and car worked fine. July 23 driving on the pa turnpike after stop/go traffic it did the same thing. It took onstar 3 hours to get us towed and a rental. They did the same repair and it worked fine. Coming home on the 28th in stop/go traffic it did it again. The dealer has the car. As of now I dont think I will feel safe driving it again!

  Highway MPG rating "FALSE" - 2010 GMC Terrain
  By M.A.Berry - July 24 - 5:32 pm

  The highway MPG is very much overstated. Im getting maybe 24-26 mpg driving the posted speed limits on the highways. In town 21-22. Driving the 4 cyl, automatic trans. So far, no mechanical problems.
