We bought a 2011 Terrain SLE-1, then had leather, DVD and sunroof added, just came out cheaper that way.
Sunroof messed up within about six months, air condition stopped working around the same time in the middle of summer. The 4 cylinder is so under powered it's pathetic and makes the worst sounds when cranking up. Also here lately it's been dying after being started.
Now the gas mileage, well it sucks! GMC must measure MPG alot different than I do, but I have never got close to 32 on the highway. The average with about 70% highway and 30% city stays at 19mpg.
We are looking to getting back into a Toyota ASAP while this thing is still running.
Send the thing back to the factory and start over!
