Product Reviews

Welcome to Consumer Reports.

We’re so glad to have you as a member. You now have access to benefits that can help you choose right, be safe and stay informed.
While this version of the GMC Terrain is not a bad vehicle, the competition had left it in the dust. While nice and roomy inside, the Terrain is less efficient than other five-passenger SUVs, but burns as much gas as larger, seven-passenger models. The 3.6-liter engine, shared with many other General Motors products, supplies quick acceleration times at the test track, but feels sluggish in routine driving.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph (sec.) 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit,
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.

Owner Reports

Worse Better
Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Road Test

While this version of the GMC Terrain is not a bad vehicle, the competition had left it in the dust. While nice and roomy inside, the Terrain is less efficient than other five-passenger SUVs, but burns as much gas as larger, seven-passenger models.

The 3.6-liter engine, shared with many other General Motors products, supplies quick acceleration times at the test track, but feels sluggish in routine driving. Plus, the unrefined and slow-shifting six-speed automatic transmission does it no favors. With 18 mpg overall, fuel economy from the V6 falls short of more capable and roomy SUVs. Four-cylinder models have an overworked 2.4-liter engine, which returns 21 mpg. Again, that falls far short of rivals, which approach 26 mpg overall. Handling and ride are decent, but ordinary.

“Even though this is a 2015 vehicle, the software was designed in 2009. The smartphones I've had did not work at all with the system. USB was incompatible with the phone. The radio could not even play now music from the phone neither thru the Bluetooth USB, or mi rophone cable”

In-dash navigation system (GPS)

“As far as I am concerned the OnStar on GM vehicles is an ABSOLUTE JOKE. Mine does NOT work more than id does work. GM should call it that "Piece of Shit" on your vehicle rather than OnStar. I can't make phone calls, you try to call OnStar by pushing the Blue Button nothing happens. One day I pushed the SOS button and 29 minutes later I finally got a response. I asked the guy, "Do you have any idea how many people have died in the last 29 minutes?" His response was you should push the blue”

Rodney B., WI (2015 GMC Terrain SLT 3.6-L V6)

“The navigation system gets "off track" and stops giving releable directions. It has been into 3 different dealerships (becasue we travel), a total of 8 times, we sent a letter to GMC via certified mail and we have had 21 telephone calls to GMC Customer Assistance. Their answer is that the technial people are workinf on a correction and they ask us to continue to be patient.
