I bought this vehicle in April 2018 and here it is September 2018 and I have had it repaired 4 times it has stopped on me multiple times while in the middle of driving with all three of my children in traffic. I have had the water pump replaced and 2 sensors replaced. This vehicle will get you and your family killed from it randomly stopping while driving anywhere.... 😡😡😡

I wish I had known about this website before purchasing a 2011 GMC Terrain. This thing is a lemon. I bought it at the end of June 2017. I made two trips from Southern Ilinois to North Carolina. I also made one trip to Nashville, TN. These long-distance trips were relatively uneventful. Ever since then it's been one problem after another. The Accelerator sensor needed to be replaced. Then the throttle body went bad which made the engine go into 'Reduced Power Mode.' That means you limp along at 20 mph. After cleaning the throttle body,(easy to remove in the 4 cylinder) it would drive around town with no problem. But on the highway, it would go into reduced power mode. If you pull over, shut the engine off, wait a minute or two and restart it, it would be fine for a short while and do it all over again. The dealer wanted $400.00 to replace the Throttle Body, but I found one for less than half that and replaced it myself. Then the catalytic converter went bad. At least GM warrantied that, but while replacing it, they found the exhaust manifold was cracked. I'm waiting for a phone call to find out if the extended warranty I purchased will cover that. One word about the extended warranties the dealerships offer, DON'T. They aren't worth the paper they're printed on. On a positive note, we get around 30 mpg highway and an average 23 mpg for both city and highway.
Criminal MPG Advertising!!!!

I have never written a review before but feel obligated to warn others of my mistake. I bought my 2011 GMC Terrain in Dec 2010. As of August 2011, I have put close to 20K miles on my vehicle...mostly all highway mileage due to outside sales. After extensive research on this vehicle, and others in its class, I went with the Terrain for the advertised highway MPG. I read all of the reviews that explicitly pointed out that the mileage fell short. I assumed that if it fell short of the 32 MPG around 26-28 MPG, that's still great. I have done everything possible to only get 22-23 MPG at best...at that is in the "ECO" mode. I've developed OCD watching instantaneous fuel economy. Terrible!
Horrible MPG

Dealer claimed 22 city and 32 HWY and I have never gotten better than 23 MPG and that was on a road trip with all highway driving. I only purchased this car because of the MPG. I would never have purchased had I know GMC lied about the MPG. I typicalley average 18-20 MPG with city and highway driving combined.
