I was actually trying to find out about an oil separator for the Terrain. I came across this forum. I must say that the issues other spoke of I have never experienced. My biggest issue with this vehicle is the power drivers seat. It has now failed twice since I own the vehicle, however the repairs were performed under the warranty and the GMPP. As far as the fuel mileage, well the 32mpg advertised is not an SLT-1 or with AWD. The AWD alone is 300 lbs. I purchased the 4cyl and found out that between the SLT trim (extra sound deadening) and the AWD, that little engine is just overworked from a standing start. However for my purposes the vehicle is just fine. I do not pull a trailer, or carry heavy loads. I go supermarket shopping and just short trips. The vehicle is very comfortable and I totally enjoy the Pioneer sound system. I have not had any issues with oil consumption, but that maybe due to my personal maintenance program. I have the oil changed 3 months/3k miles, not 7500 miles as recommended. I have had the vehicle dealer serviced 100%, and the dealer is just wonderful. I do not drive the vehicle hard. But I took delivery on April 30th, 2012, and currently have about 23k miles on it. My daily driver is a 2015 Subaru Outback Limited 2.5i. The Subaru's 175 hp 4 cyl has way more low end torque than the 185 hp 4 cyl in the Terrain. Other than my error in ordering the 4cyl, I love the Terrain. It has performed as I expected and hoped.
We have a 2012 STL-1 and couldn't be happier. It has more than 119,000 miles on it and not one serious mechanical issue. We had one check engine light issue. It was a minor repair costing less than $100.00. We've never had to add oil between changes. As far as fuel mileage, we average 26.6 overall, 22 in town and 29.8 on the highway at 68 MPH, our normal highway speed. In town, we don't make jack-rabbit starts and approach stop signs slowly. Also, dealers, no matter the company, are required to use the EPA fuel mileage estimates. They test these cars with no passengers, no wind resistance, no A/C with no stops and starts. Chances of getting the published fuel mileage is very unlikely. The dealership isn't lying, in most cases. They just report the EPA findings.
The car is comfortable and a pleasure to drive. Every thing has worked as it should from day one. A far as those folks who complain about the turning radius, "mushy" brakes and relatively slow acceleration ... did you not drive the vehicle first? If so, you should have noticed these things before your purchase. If you didn't test drive it, then you have no one to blame but yourself. Our dealer let us test drive for about 15 miles, part in town, part on the highway. Of course, you would have had no idea about the oil consumption issues several folks have mentioned. That would not be your fault.
We are very leased with our Terrain. And no, I am not in anyway connected to General Motors. This is the first General Motors product I have owned since a 1960 Chevy station wagon I bought in 1974. Here's wishing everyone the best of luck with their GMC Terrain.
This 4 cyl is fully capable of annual trips to Florida Keys, LOADED with 2 kayaks on top, 2 bikes on behind and pulling a small boat trailer while getting satisfactory mileage . MPG is much better at 60 than at 75 mph! Very comfortable car.
