The 2010 Terrain debuted in April 2009 at the
New York International Auto Show, introduced as a replacement for the
Pontiac Torrent, which ended production after GM shut down the Pontiac brand in 2010. Although the preceding Pontiac Torrent had the same Theta platform, the Torrent was a
rebadged version of the original
Chevrolet Equinox from 2005 to 2009, while GM decided to differ the look of the Chevrolet Equinox with its 2010 Terrain and still use the Theta platform. Early 2010 models had the GM Mark of Excellence logo applied on the sides of the vehicle. The Terrain initially came in SLE and SLT trims. 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. For the 2013 model year, a
Denali trim was added, featuring additional chrome trim (including unique exhaust tips), slightly improved interior quality, and firmer front struts. The Denali also offered cross-traffic detection, blind-spot warning, and a power passenger seat as options, but unlike many of its competitors, dual-zone climate control was not available. A low-end SL trim was added for 2015; derived from the SLE-1 trim, it was only available with front-wheel drive and the 2.4-liter Ecotec engine, and had very limited option availability.
2016 refresh For 2016, the GMC Terrain received a facelift as part of its first mid-cycle refresh along with the Equinox. The refreshed version debuted at the 2015
New York International Auto Show. The refresh consisted of new front and rear fascias, chrome exhaust tips (first used on the 2013 Denali) 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. The rear door child safety locks are now manual instead of electronically controlled. 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. The Terrain Nightfall came with revised rims with machined faces and black spokes. The Terrain Nightfall trim was available on the SLE-2 and SLT trim levels and was available only in Onyx Black, Summit White, Graphite Gray, and Crimson Red.

Engines The first-generation Terrain was powered by a choice of two engines, a 2.4-liter four-cylinder and a V6 engine that was upgraded from 3.0 liters of displacement to 3.6 liters for 2013. Flex-fuel (E85) capability was offered as an option on four-cylinder models from 2012 to 2017 (2015–2017 FWD only) and V6 models from 2011 to 2014. Notes: • All four-cylinder models have a single rear exhaust port (on the left), while all V6 models have dual rear exhaust ports. • All ratings are on regular gasoline.
Natural gas version In 2013, Nat G CNG Solutions in Houston, Texas, and AGA Systems in Salt Lake City, Utah, began offering a
Compressed Natural Gas (CNG) version of the Terrain and the
Chevrolet Equinox using the 2.4L Direct Injection engine. The natural gas version is a "bi-fuel" CNG vehicle, meaning it runs on either gasoline or natural gas, giving it extended range. The Terrain/Equinox were the first direct injection natural gas vehicles ever approved by the US EPA. The CNG version was available for newly purchased Terrains through select dealers or as a retrofit on 2013 and 2014 models. Nat G CNG Solutions offered the vehicle in two options: a two-seater cargo version and a five-seat passenger version. The cargo version had an combined gasoline/natural gas highway range (9.2
gge of CNG), while the passenger version had a combined highway range (6.8
gge of CNG). File:Terrain-Passenger small.jpg|

Recall In March 2022,
General Motors recalled over 740,000 GMC Terrain models made from 2010 to 2017 for
headlights being excessively bright. In October 2022, General Motors issued a fix for the recall by thoroughly cleaning the headlights and applying a translucent decal on the headlight.
Safety 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. ==Second generation (2018)==
