While the GMC Terrain and its twin the Chevrolet Equinox are not bad vehicles, the competition has left them in the dust. They split the difference between small SUVs such as the Toyota RAV4 and midsized models like the Ford Explorer. While they're nice and roomy inside, the Equinox and Terrain are less efficient than other five-passenger SUVs and burn as much gas as larger, seven-passenger models.

Reliability

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey, our reliability history charts give you a rundown on how used vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for about 329,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2020 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA 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 Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2017 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.

L L., TX (2017 GMC Terrain SLT)
External music device interface (e.g., smart phone, MP3 player)

"When connected to my iPhone and listening to an audio book, if i put the car in reverse it disconnects the phone and switches to playing the radio but at a volume much louder than what I was listening to while the audio book was playing."

Anonymous, NY (2017 GMC Terrain Denali 3.6-L V6)
In-dash navigation system (GPS)

"The Nav interface is difficult to read and the maps are outdated"

Curt D., MO (2017 GMC Terrain Denali 3.6-L V6)

"Noise around driver door"

Patrick H., WV (2017 GMC Terrain SLE 2.4-L 4 Cyl)

"the wind noise is prevalent above 50 km/ hr and increasingly gets noisier as speed increases. The majority of my driving is short trips around town, at which speeds the wind noise is slight, but on a major highway it is annoying. I put up with it."

Anonymous, ON (2017 GMC Terrain SLE 3.6-L V6)

"It appears to be in the design of the vehicle as per the technicians evaluations. I am not happy with that. It is a brand new vehicle and should not have any noises!"
