87,000 miles and switching

Vehicle: 2010 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

We bought our 2010 Terrain new. My wife drives daily to work and in less than 3 years we already have 87,000 miles. We bought the car because we were informed that the mpg would be 31 or so. We've never gotten better than 27 and usually we're at 24-26 mpg with the 4 cylinder on eco. We've had problems with the lift gate, timing chain knocking, and at 80,000 miles we changed the tranny oil. It was black! Since then we've continued to feel it slip. Driving in the back seat is a horrific experience for people with good backs! It's too straight up and down. The AC has broken down twice in 2 years!

Worse vehicle i have ever

Vehicle: 2010 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

We have never had so many problems with a new vehicle as we have had with this one. They had to replace timing chain, a rattling noise is still very loud but they tell us there is nothing wrong, drive the car to work and back and no engine light turned on or anything just a loud knocking noes in the motor every time we pressed gas.. Little did we know that the car had no engine oil... But it still showed it had 40% oil life. Don't know where the oil is going. This is the second time it's happened to us. We have to check oil at least every 2 weeks.. This is a 2010 car. Mileage is not what it says it is..

Very nice

Vehicle: 2010 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

The number one reason for buying the 4 cyl. Terrain was the 32 MPG Hwy. advertised. This could not be more wrong. We recently drove over 2400 miles which most was interstate highway and averaged only about 25 MPG. We are senior citizens and this was mostly on cruise control at less that the listed highway speed. We are very disgusted with this poor hwy. mileage and will certainly not recommend this vehicle to friends and family.We could have bought another Town and Country which is a 6 cyl. and we averaged over 25 MPG on the last one we owned prior to the Terrain.

Love our terrain

Vehicle: 2010 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

I'll start out by saying my only complaint with our Terrain is the turning radius isn't that great. It doesn't always bother you but on making u turns you sometimes have to back up if the road isnt wide. Other than that we LOVE our Terrain. I read someone said it took 3 hours for onstar to get someone to them. IT probably took 3 hours for whomever was coming but be happy onstar was there. Ive had to use onstar several times and in a accident. That voice coming over automatically telling me help is on the way and I don't have to look for a cell which mine was broken. Its awesome to know my car will help me if needed. I love the comfort, the looks. I have people all the time stop me to say its nice!!

Never again

Vehicle: 2010 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

Worst engine noise ever - told it is normal. Road noise even with noise cancellation system awful. Nice to look at - not to drive. Gas mileage disappointing. Hate red dash lights and bright chrome in center of dash. GM's answer was sell it, turn the radio up and/or it is only noise get over it. Fuel injectors, fuel pump, valve lifters - sounds like a diesel. Loyal GM owner for 40 plus years - never again.

What's New for 2010

The 2010 GMC Terrain is an all-new small crossover SUV.


On the one hand, the 2010 GMC Terrain is an old-school GM badge job, an unabashed Chevrolet Equinox knockoff with the same platform, features and powertrains. But unlike many old-school GM badge jobs, this one is fundamentally a really good vehicle, so we're willing to cut it some slack. Indeed, the Terrain and its Equinox sibling look set to shake up the small-to-midsize crossover SUV segment that Honda and Toyota have long dominated.

The 2010 Terrain benefits from the same updates as this year's redesigned Equinox. Under the hood is a torquey base four-cylinder that offers best-in-class fuel economy and competitive acceleration. There's also an available direct-injected 3.0-liter V6 that's similarly competitive in terms of fuel economy and power. Inside, the Terrain boasts a snazzy center stack and attractive control layout that make its rivals' cabins seem dull and unimaginative by comparison. An abundance of acoustic insulation and an innovative noise-canceling system also make the Terrain one of the quietest compact crossovers around.

The Terrain isn't quite fault-free. Its maximum cargo capacity, for instance, isn't as generous as that of some competing models. But otherwise it's pretty hard to find fault with GMC's new SUV. The 2010 GMC Terrain offers just about everything that shoppers in this segment are looking for, and it's one you'll definitely want to cross-shop along with established models like the Ford Escape, Honda CR-V, Mitsubishi Outlander, Nissan Rogue and Toyota RAV4.

Body Styles, Trim Levels, and Options

The 2010 GMC Terrain is a midsize crossover SUV available in four trim levels: SLE-1, SLE-2, SLT-1 and SLT-2. Standard equipment for the SLE-1 includes 17-inch alloy wheels, heated side mirrors, a trip computer, cruise control, air-conditioning, full power accessories, power front seat height and lumbar adjustments, a sliding and reclining backseat, a tilt-and-telescoping steering column, a back-up camera integrated into the rearview mirror, OnStar and a six-speaker CD stereo with satellite radio and an auxiliary audio jack. The SLE-2 adds roof rails, 18-inch alloy wheels on V6 models, an eight-way power driver seat, a leather-wrapped steering wheel, Bluetooth, automatic climate control and an eight-speaker Pioneer sound system.

The SLT-1 has the aforementioned plus 18-inch alloy wheels, remote engine start, leather upholstery and heated front seats. The SLT-2 ups the ante with chrome exterior trim details, a unique grille, driver memory functions, a sunroof, a power liftgate and rear parking sensors. Additional options, depending on the trim level, include a hard-drive-based navigation system (with larger rearview camera display and 40GB of music storage) and a rear-seat entertainment system. Some of the extra features found on the upper trims can also be added to the lower trims as options.

Powertrains and Performance

Every GMC Terrain comes standard with a 2.4-liter four-cylinder engine producing 182 horsepower and 172 pound-feet of torque. Optional on all but the SLE-1 is a 3.0-liter V6 good for 264 hp and 222 lb-ft of torque. Both engines come standard with a six-speed automatic transmission and front-wheel-drive; all-wheel drive is optional across the board.

Fuel economy is impressive. A four-cylinder Terrain with front-wheel drive achieves an EPA-estimated 22 mpg city/32 mpg highway and 26 mpg combined. All-wheel drive lowers these estimates to 20/29/23 mpg. A Terrain V6 with front-wheel drive gets 17 mpg city/25 mpg highway and 20 mpg combined, with all-wheel-drive versions dropping only incrementally to 17/24/20. The maximum tow rating when properly equipped is 3,500 pounds with the V6.


The 2010 GMC Terrain comes standard with antilock disc brakes, stability control, front seat side airbags, side curtain airbags and OnStar. Rear parking sensors are optional.

Interior Design and Special Features

The GMC Terrain's cabin is remarkably stylish, particularly by the standards of this typically utilitarian segment. The slick-looking dashboard design is reminiscent of the related Cadillac SRX, and the Terrain's high-tech navigation and entertainment options only heighten its appeal.

In terms of accommodations, the Terrain's backseat is roomy for this class and conveniently reclines and slides fore and aft (to allow easier access to child seats or to expand cargo capacity). Cargo space behind the backseat is 31.4 cubic feet, and that figure grows to 63.7 cubic feet with the rear seats folded. That's about 6 cubes shy of the Honda CR-V and Toyota RAV4, but still bigger than smaller crossovers like the Ford Escape and Nissan Rogue.

Driving Impressions

The 2010 GMC Terrain accelerates well with the new four-cylinder engine, and its 32-mpg highway rating with this engine is most impressive. This engine should satisfy most folks, but for those wanting more there's the optional V6. The optional mill is a bit short on low-end torque relative to the RAV4's standard-setting V6, but otherwise it's one of the strongest engine choices you'll find in this segment. On the move, the new Terrain is impressively quiet, and the ride is comfortable. However, we'd suggest sticking with the smallest possible wheels, as the larger ones increase impact harshness. Handling capabilities are nothing special, but most drivers should be satisfied by the vehicle's all-around competence.
