2011 Terrain MPG Experience

I recently purchased the 2011 Terrain SLE-1 for its comfortable ride, features, and gas mileage claims. Although Ive read a number of user reviews stating disappointment with gas mileage, Ive averaged 21-22 mpg in the city, and on recent highway trips averaged 30 mpg and 31mpg on trips through OH, WV, and VA, on significantly hilly terrain. On a 150 mile trip over more gentle rolling hills, I averaged 33 mpg. I used the Eco mode, cruise control, and adjusted my driving habits for maximum fuel efficiency, but that was in no way inconvenient, and I've been very pleased.

Purchased our 2011 GMC Terrain Feb 2011 and still waiting for 32 mpg. If I knew the mileage was going to suck I'd purchase the V6 to give me better pick up, passing acceleration, and cruise control performance going up freeway hills. We love our Terrain except for the engine and mpg. The best mileage experienced on our trips to Utah and Arizona from California is 23.2. Currently in the city 21.2. Where's the miles per gallon as advertised. Just saw a 2013 Terrain commercial on TV last night (3/25/12) boasting 32 mpg. Both my wife and I laughed!

It's not a power train. But it's got the power to pull a train. I would take this SUV any where I could take my Z71 4×4.

Poor gas mileage / back up camera inside vehicle

Gas mileage is not good at all, never had the 32mpg as I was told. Going back and forth to work I average in the summer 29 mpg and in the cold it is even lower, highway driving is even less. Other vehicles I have owned gave me a higher gas mileage than stated on the highway sticker miles going back and forth to work, terribly disappointed with the Terrain. Talked to the dealer and he confirmed there were complaints it wasn't getting the predicted gas mileage. Back up mirror is not reliable, only shows directly behind you without even a little bit of a side view
Absolute Junk!

High-pressure fuel pump was recalled, as was the catalytic converter. Now it's burning oil and needs new rings says the dealership. Most recently when you start the car exhaust fumes pour through the vents. Although the car is good looking and has a comfortable interior and lay out, mechanically, the car is a nightmare. It has horrible pick up especially with the air conditioning on. And just the other day the A/C compressor died. Not I have to invest $700 more in to this car. Replaced the catalytic converter and whole exhaust recently as well. Big mistake buying a Terrain!
