  cute car but unreliable with ongoing issues - 2010 GMC Terrain
  By aestabrook - March 7 - 12:48 pm

  I purchased this car new in 2010. within 6 months there was trouble. oil issues, check engine light with no real causes, throttle body replacement, stalling on the highway, stalling on side roads, general unreliability. I have been towed into the dealer 9 times since purchase for dying on the side of some road. It burns oil for no reason. GMC and dealer just say too bad, and tell me to check it every 1000 miles between oil changes. I typically add between 1 to 2.5 quarts every 1500 miles. The car is comfortable, and spacious for having two car seats in it, BUT that comfort does not outweight its ongoin challenges. I would get rid of it if i had the money to.

  Most unreliable vehicle ive ever owned - 2010 GMC Terrain
  By tpregnar - February 20 - 12:07 pm

  My first car cost $17,000 less than my terrain and was 100% more reliable. Lots of warranty work was done on the engine before the engine needed to be rebuilt. After it was rebuilt the gas mileage plummeted. then the transmission blew just out of warranty. Would have been nice to be able to check the transmission fluid without crawling under the car, but there is no dipstick. Absolute waste of money and the last gm product I will own.

  Not worth buying - 2010 GMC Terrain
  By bxgirl - November 6 - 9:03 am

  Purchased my Terrain soon as it hit dealerships during its release. Ive never visited a dealership so many times and have had so many problems with a vehicle. Since having this vehicle Ive had problems with the vehicle shutting off in the middle of intersections due to the senor oxygen (engine control) needing to be replaced to due cold starting the vehicle, the rear control arm bushings, the stabilizer shaft, the exhaust manifold all of which needed to be replaced. Now, GM was trying to hit me over the head and charge me for the timing chain which they try putting on me for not changing the oil. Luckily I saved all my receipts and they had to eat the $847 bill.

  Big lemon - 2010 GMC Terrain
  By somerside - September 10 - 1:10 pm

  I bought this terrain just over a year ago and have had nothing but problems. In its 4 years of being on the road its had the motor rebuild due to oil consumption issue. Its had the timing chain replaced twice. The AWD system has malfunctioned. The sunroof is broken. The navigation unit has been changed twice. Numerous sensors have been replaced. The emissions system has been a nightmare. Ive spent a lot out of pocket cause most of it has not been under warranty. Im very disappointed in the quality that GM has put into the first gen terrain. Overall the vehicle so unreliable that I cant trust it for my wife to drive back and forth to work. I do not recommend this vehicle at all.

  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.

  87,000 miles and switching - 2010 GMC Terrain
  By drstubb1 - November 6 - 2:53 pm

  We bought our 2010 Terrain new. My wife drives daily to work and in less than 3 years we already have 87,000 miles. We bought the car because we were informed that the mpg would be 31 or so. Weve never gotten better than 27 and usually were at 24-26 mpg with the 4 cylinder on eco. Weve had problems with the lift gate, timing chain knocking, and at 80,000 miles we changed the tranny oil. It was black! Since then weve continued to feel it slip. Driving in the back seat is a horrific experience for people with good backs! Its too straight up and down. The AC has broken down twice in 2 years!

  Malfunctions - timing change, noise, oil pouring out - 2010 GMC Terrain
  By dlatour - June 9 - 3:32 pm

  At 35,000 miles the timing change had to be changed. At 51,000 miles I brought it in for engine noise that was extremely loud and an oil film on the undercarriage. Told that the noise and oil was normal. Today at 54,000 miles it appears all of the oil drained out of the motor. Beside the huge puddle on the driveway there is oil from the front of the car to the rear of the car.

  Worse vehicle I have ever had! - 2010 GMC Terrain
  By texas322 - April 7 - 9:31 pm

  We have never had so many problems with a new vehicle as we have had with this one. They had to replace timing chain, a rattling noise is still very loud but they tell us there is nothing wrong, drive the car to work and back and no engine light turned on or anything just a loud knocking noes in the motor every time we pressed gas.. Little did we know that the car had no engine oil... But it still showed it had 40% oil life. Dont know where the oil is going. This is the second time its happened to us. We have to check oil at least every 2 weeks.. This is a 2010 car. Mileage is not what it says it is..

  New engine in just under 3 years - 2010 GMC Terrain
  By rhoda13 - February 4 - 1:56 pm

  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.
