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 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.

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.

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.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2015 GMC Terrain owners. The owner comments describe problems respondents experienced with this vehicle.

In-car Electronics

CD or DVD players, radio, speakers, GPS, communication system (e.g., OnStar), display screen freezes or goes blank, phone pairing (e.g. Bluetooth), voice control commands, steering wheel controls, portable music device interface (e.g., iPod/MP3 player), backup or other camera/sensors.

What Owners Say

Display screen freezes up

"The whole infotainment system died , for the second time . The first time was under warranty and the second time I had to pay the labor on it even through it was only a few days out of the three year warranty !"

James S., WI (2015 GMC Terrain Denali 2.4-L 4 Cyl)

"Rear Camera and Side Detector froze then showed numerous safety warnings until the dealership had it fixed."

Don R., MI (2015 GMC Terrain Denali 2.4-L 4 Cyl)

"Back-up camera would not go off when the car was in drive."

Anonymous, MI (2015 GMC Terrain SLE 2.4-L 4 Cyl)

"Stops functioning completely. Will reboot after several minutes but nothing will work till it reboots"

Ralph S., NH (2015 GMC Terrain SLT 2.4-L 4 Cyl)
Display screen goes blank

"This is the second time this happened in 1 year . The first time the dealer said it was software related . This time they replaced the whole infotainment system . But I had to pay the labor on it ."

James S., WI (2015 GMC Terrain Denali 2.4-L 4 Cyl)

"Display goes blank and radio and navigation fails. Navigation will actually display different city and streets and give directions to places not around area. System will completely blank out and radio and air quits working. They have replaced radio twice and antenna twice. It works for awhile then starts all over again. No display--nothing. Then the wind noise. I can't use the blue tooth in the car because it can't make out what I am saying . It tells me there is too much background noise. This is because of wind noise. Dealership said noise is normal. Mileage is really bad. I have a 6 cylinder. I drive very easy and it doesn't matter. Sometimes I get only 14 around town. If it wasn't for freeway miles, it would be worse. Car handles good but turn radius for size sucks. My Yukon for size was better. It has about same turn radius. Their best car was the 2000 Jimmy. It ran forever."

Anonymous, CA (2015 GMC Terrain SLT 3.6-L V6)

"They won't check it out unless they see it. Something new with GM dealers, we can't fix what we can't see. They don't even try to diagnosed the issue"

Joseph P., NY (2015 GMC Terrain SLE 2.4-L 4 Cyl)

"Replaced 2 computer modules that corrected the problem"

Anonymous, CT (2015 GMC Terrain Denali 3.6-L V6)

"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"

Joseph P., NY (2015 GMC Terrain SLE 2.4-L 4 Cyl)

"It is impossible to pair. It is slow. It farts out when you restart the car and has trouble pairing up again. I don't care for Intellilink"

In-dash navigation system (GPS)

"Did not find actual location of vehicle."

Anonymous, WI (2015 GMC Terrain SLT 3.6-L V6)

"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. GMC acknowledged there is a problem with the navigation system in several models in Document ID: 4174284 #PIC6057A released"

Tom W., FL (2015 GMC Terrain SLE 2.4-L 4 Cyl)

"Locks up and car must be shut down and restarted to reboot system"

"Dealership diagnosed GPS component needed replacement for $800.00. I said no but it was working when I left and still is working."

Larry K., MI (2015 GMC Terrain SLE 3.6-L V6)
Phone pairing (e.g., Bluetooth)

"It has maintained pairing with my wife's phone and she is the one that normally drives it. However, it lost the pairing to my phone and I cannot reestablish it."

Anonymous, NM (2015 GMC Terrain SLT 2.4-L 4 Cyl)
Radio

"AM/FM radio does not work, Use rarely as I have SIRRUS, when reported to dealer, it was over 30 day warranty and the charge will be $200!!!"

Sharon V., OH (2015 GMC Terrain SLT 2.4-L 4 Cyl)
Voice control commands

"Voice control won't work because of the wind noise. I always get the message. There is too much background noise I've told the dealership since I bought the car and I have an SLT model. I hate to think what an SLE is like. So I can't use the Bluetooth features. I upgraded and paid for the $2500 package which is worthless to me. I would never buy that again. I use my phone most of the time for navigation. Next time I would spend a couple hundred and buy a Garmin. I don't get the updates unless you pay extra every 2 years for GMC updates for $150 plus their navigation yearly of $199. Otherwise you have to have Sirius and their monthly subscription plan. It doesn't matter because my Bluetooth can't be heard. I can't make the phone calls on their system etc. Their system hold you hostage."

What Owners Say

Automatic climate control

"Using heat or air conditioner, the fan changes to half speed when the ECO button is pushed. Also, you can turn up the heat temp control with no result. Must turn it way up to have any change. Worst heat/air conditioning control system I have seen"

"Vehicle will not maintain a constant temp on longer trips,it is constantly blowing hot then cold air searching for correct set temp."

Blower (fan) motor

"OK! It isn't actually the Blower (fan) motor that went out, but squirrels or rodents had stored about two cups of dog food in the Blower (fan) motor compartment which caused a loud noise and tremendous vibration when the fan motor was engaged at medium to high speed. Would expect GMC to encase the blower motor fan so this could not happen."

Robert C., BC (2015 GMC Terrain Denali 3.6-L V6)

"About 2500 miles after a four wheel brake job including all new on the front and turned rotors on the rear, the rears developed a clicking noise. Had them cleaned and lubed at 2500 miles. Noise re-appeared after another 2500 miles. Cleaned and lubed again at dealer second time. Noise re-appeared a third time and had pads replaced at original shop. It is just now another 2500 from new pads but no signs of noise yet. Fingers are crossed. Shop said if it happens again it most likely could be some wear on calipers not pads. Have had many years of good work at this independent shop."
