All models included a backup camera, AM/FM/CD/MP3 radio with USB port, laminated front door glass and tempered deep-tinted rear glass, Multi-Flex fore/aft adjustable rear seat, telescoping steering wheel, four-wheel independent suspension, and four-wheel vented disc hydraulic anti-lock brakes.

The Denali also offered cross-traffic detection, blind-spot warning, and a power passenger seat as options, but unlike many competitors, dual-zone climate control was not available.

The refresh consisted of new front and rear fascias (including chrome exhaust tips on all models), a power dome hood, LED daytime running lights, new wheels, a new gear selector, a second storage shelf under the dashboard (in the place of the discontinued CD player), as well as the deletion of the door lock buttons from the dashboard.

For 2017, GMC introduced the Terrain Nightfall edition, replacing chrome with gloss-black finish on the grille surround, the front and rear fascia accents, the license-plate surround, mirror caps, and roof rack, as well as charcoal grille inserts and darkened headlights pulled from the Terrain Denali.

[8][9] The 2010 model year Terrain was awarded "Top Safety Pick" by IIHS, it received the highest-possible rollover protection rating of Good and achieved the Good rating for the roof strength test because its roof can withstand a force equal to four times the vehicle's weight.

The headlamps and taillamps now feature LED lighting accents, and the top-of-the-line GMC Terrain Denali was initially only available with the 2.0-liter turbocharged engine, which included dual chrome exhaust tips and larger front brakes.

With this generation, the interior is quite different from the contemporary Chevrolet Equinox, with all models featuring a folding front passenger seat to accommodate items up to eight feet long, a class-exclusive switch-based transmission shifter, under-console pass-through storage area, a storage compartment above the glove box, and a leather-wrapped steering wheel.

[18] It was initially planned to go on sale in mid-2020 for the 2021 model year, but production issues and the COVID-19 recession led General Motors to cancel the GMC Terrain facelift in March 2020.

[19] The refreshed Terrain features an updated front and rear end, exterior LED lamps, and interior.

LED signature daytime running lamps, Wireless Apple CarPlay and Android Auto, engine start/stop disable switch, and automatic air conditioning are now standard on all models.

The redesigned exterior gives the crossover a more rugged, truck-like appearance, aligning it closely with the rest of the GMC lineup.

Key exterior features include distinctive C-shaped lighting signatures in the headlights and taillights, a bold grille design reminiscent of GMC’s larger trucks, and standard 17-inch wheels.

Other convenience and safety features include up to eight available camera views, 5G Wi-Fi, and windshield wiper de-icing grid.
