  Did not realize what i was getting into - 2010 GMC Terrain
  By Chris Little - November 6 - 2:47 pm

  i bought the SLE 2.4l AWD in 2014, the vehicle was already 4 years old with 80k miles on it. before i drove it off the lot, noticed the utility charging plug in the front storage compartment did not work, and the USB port in the center console did not work. told the dealer and they said they would handle it, no one ever called me. as the year progresses that i have the vehicle, i start smelling small amounts of exhaust in the cab and think nothing of it. this week, 11/2/15 - 11/6/15 the check engine light came on and gave a P0011 code, took it to the dealer and found it was crank shaft alignment sensor, the dealer recommended replacing the actuator for it and also doing the exhaust sensor and actuator. $900 later, because the extended warranty that i purchased would not cover the work performed, the exhaust i smelled in the cab became 10 times worse. took it back to the dealer and had them look at it free of charge. i now have a cracked exhaust manifold. this crack does not show up over night, which means when i bought it, the manifold probably had a small fracture in it. and yet again, my extended warranty will not cover this repair either. dealer wants over $500 to fix this, sorry.. i got my complementary inspection, im going somewhere else for the repair. dont get me wrong, the fuel economy on this vehicle is great and it is a good looking car. i, however, do not like having to fork out this much money on a vehicle when i have only owned it for a year now and still making payments on it. my 2002 GMC Sierra has given me less trouble, and its 13 years old now.

  Lemon in the making - 2010 GMC Terrain
  By ericdm33 - April 2 - 10:33 am

  I was really looking forward to owning this vehicle when I purchased it. Now just 5 years and 70k miles in, Im currently dealing with my 3rd breakdown. This was my first American built vehicle ever, and it may very well be my last.

  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.

  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.

  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..

  Never Again - 2010 GMC Terrain
  By Never again - August 5 - 8:12 pm

  Worst engine noise ever - told it is normal. Road noise even with noise cancellation system awful. Nice to look at - not to drive. Gas mileage disappointing. Hate red dash lights and bright chrome in center of dash. GMs answer was sell it, turn the radio up and/or it is only noise get over it. Fuel injectors, fuel pump, valve lifters - sounds like a diesel. Loyal GM owner for 40 plus years - never again.

  Wheres my old suv? - 2010 GMC Terrain
  By debbie - July 14 - 9:59 pm

  If I had it to do all over again I would never have traded my envoy, the get up an go of the terrain has never got up to my expectations I had a 8 cyl and now have a 6 cyl. No power! And gas is no better than my 8 cyl. Anyone thinking about buying a terrain think twice! Ive never been as unhappy as now, so if you see my 2005 envoy, please tell it to come back home!

  Poor gas mileage - 2010 GMC Terrain
  By cecilp - April 22 - 8:09 am

  Have less than 2000 miles on vehicle. Gas mileage not even close to rated numbers. Reported to dealer and all I get is this "Use the SAME pump at the SAME station with vehicle pointing in the SAME direction with the SAME number of people in vehicle". Is this a crop or what. Here are numbers: Hiway driving (cruise set at 60 MPH) 141.7 mile trip used 9 gallons (thats 15.75 MPG period) City driving 140.2 miles (normal stop and go traffice) with 9 gallons to fill back up (thats 15.58 MPG PERIOD) Dealer says this is not true mileage as there are possiable BUBBLES in tank while filling are fuel pumps regulated and must deliver what is metered out? Instruments say 17 MPG on console
