Transmission Jerks when putting it in reverse

AF, Jonesville, NC, 07/20/2015
2012 GMC Terrain SLT-1 4dr SUV AWD (2.4L 4cyl 6A)
I have the 2012 GMC Terrain and for the last few years it sporadically jerks/kicks/slips when I first put it in reverse to drive out of the garage. It's not consistent so the dealer can't diagnose it and it never does it when I try to show it to someone. I've been told that this isn't a problem, but it still makes me nervous. Other than that, I love the Terrain!

7 Years in and Happy

Coldwaterite, Fort Wayne, IN, 10/07/2018
2012 GMC Terrain SLT-1 4dr SUV AWD (2.4L 4cyl 6A)
We bought this new in 2012. We now have 102,000 miles on it. Out side of normal servicing the only problem we've had is the Key fob broke and had to be replaced. Love it's comfort, love the adjustable back seat, it's easy to get into and out of. Mileage is "great" if we keep under 65 mph we can get over 32 mpg; once you hit 70 mph it drops to 27 mpg; in town it'll drop to 23 mpg. … It has served us well and hope to keep it for another 4 years. Like the looks of the new 2018 but it looks like the mileage has dropped off substantially, so why trade down when she's still purring like a kitten. Wish we had the automatic lift gate, that'd be nice now that were getting older. October, 2019: Due to the generosity of an old friend we traded our beloved 2012 in for a new 2019 Terrain SLT this past April. He left the dealer a check paying for 20% of the 2019. Along with that and other incentives we were able to get the 2019 for less than half price. Surprisingly gas mileage on the 2019 is much better (as long as the A/C is not on). After the first 9000 miles we have saved over $120 in fuel cost. I'll post a review of the 2019 Terrain shortly.

Junk Parts in Car and Junk Manufacture

2012 GMC Terrain SLT-1 4dr SUV AWD (2.4L 4cyl 6A)
do not buy this vehicle. I am over 60 and have had over 30 cars in my life. this one is the WORST as to mechanical problems. I bought two of these, one for me and one for my educator daughter. Bottom line: this car gets terrible gas mileage, lucky to get 19 on the interstate. It loses oil that "vanishes"; such as all oil gone after 4,000 miles- bone dry. and out of oil after oil change … and 1500 miles. Brake job after 20K miles. Replace S belt after 20K miles. I have NEVER had a car that has lost oil like this, even "oil burners"; never a brake job after 20K miles, should go 40K. and NEVER EVER loss of the sperpentine belt. and I am absolutely certain that problems will continue and more come

I love my 2012 Terrain SLT-1 AWD

RandiRN, Philadelphia, PA, 07/25/2016
2012 GMC Terrain SLT-1 4dr SUV AWD (2.4L 4cyl 6A)
I no longer own the Terrain. I traded the Terrain in when I purchased a 2021 Subaru Ascent Touuring. I was asked to update my review of the Terrain, Well, my issue at this time is with GM and specifically Mary Bara. I had an issue with the sun roof drain, the drain tube broke. This caused water to seep into the passenger cabin and finally caused mold to grow in carpet. The vehicle was … covered by a GMPP, yet GM and yes Mary Bara refused to cover the cost of the $1400 repair. The selling dealer even offered to cover my insurance deductible (auto insurance covered the repair) but I turned down the offer. It was up to GM to pay for the repair. Since GM was a bunch of jerks, my Terrain will be the last GM vehicle in my driveway. As much as I do enjoy owning the Terrain, I cannot continue to do business with a company who has forgotten where the revenue comes from. I told the dealer principle that if he obtains another brand, I will do business with him. I was actually trying to find out about an oil separator for the Terrain. I came across this forum. I must say that the issues other spoke of I have never experienced. My biggest issue with this vehicle is the power drivers seat. It has now failed twice since I own the vehicle, however the repairs were performed under the warranty and the GMPP. As far as the fuel mileage, well the 32mpg advertised is not an SLT-1 or with AWD. The AWD alone is 300 lbs. I purchased the 4cyl and found out that between the SLT trim (extra sound deadening) and the AWD, that little engine is just overworked from a standing start. However for my purposes the vehicle is just fine. I do not pull a trailer, or carry heavy loads. I go supermarket shopping and just short trips. The vehicle is very comfortable and I totally enjoy the Pioneer sound system. I have not had any issues with oil consumption, but that maybe due to my personal maintenance program. I have the oil changed 3 months/3k miles, not 7500 miles as recommended. I have had the vehicle dealer serviced 100%, and the dealer is just wonderful. I do not drive the vehicle hard. But I took delivery on April 30th, 2012, and currently have about 23k miles on it. My daily driver is a 2015 Subaru Outback Limited 2.5i. The Subaru's 175 hp 4 cyl has way more low end torque than the 185 hp 4 cyl in the Terrain. Other than my error in ordering the 4cyl, I love the Terrain. It has performed as I expected and hoped.

Full Edmunds Review: 2012 GMC Terrain SUV

What’s new

For 2012, the GMC Terrain gets a standard touchscreen audio interface that can be paired through Bluetooth audio streaming to Internet-based services like Pandora and Stitcher (late availability). Lane departure warning and forward collision alert are also now available as options.

Edmunds says

Just like the similar Chevrolet Equinox, the 2012 GMC Terrain is a top choice for a compact crossover SUV.

Vehicle overview

While it's rare to hear words like "stylish" and "sophisticated" used to describe a compact crossover, they're a fitting characterization of the 2012 GMC Terrain. Underneath its squared-off bodywork, the Terrain is nearly identical to the Chevrolet Equinox right down to the four-cylinder and V6 engines under the hood. Size-wise, the pair splits the difference between the compact and midsize crossover categories, a fact that makes them more fuel-efficient choices without sacrificing much of the practicality of traditional SUVs.

For 2012 the Terrain gets a few small but significant changes, including E85 flex-fuel capability on its 2.4-liter four-cylinder. More important to most buyers are the high-tech standard feature upgrades in the passenger cabin, including a touchscreen audio interface that also integrates the standard rearview camera display. A new Bluetooth system called Intellilink, which arrives late in the model year, makes it possible to control smartphones with voice commands and stream audio content from online sources such as Pandora and Stitcher radio.

What don't change are things like a refined ride and handsomely styled interior that's also whisper-quiet thanks to the generous use of acoustic insulation and a high-tech noise-canceling system. The cabin also earns high marks for passenger comfort, with nearly as much room as some midsize crossover SUVs like the Ford Edge.

The 2012 GMC Terrain has a lot going for it, but the same can be said for a few of its competitors in the compact crossover segment. Specifically, we'd recommend driving it back-to-back with rivals like the Honda CR-V, Subaru Forester and Toyota RAV4, all of which offer more agile handling, better visibility and more cargo capacity. On the other hand, they feel a little less substantial and well-suited to a road trip than the Terrain. Add in its bold, trucklike looks and high level of refinement, and this "little" GMC is well worth considering, especially for those downsizing from a bigger SUV.

2012 GMC Terrain models

The 2012 GMC Terrain is a midsize crossover SUV available in SLE and SLT trim levels, each of which is subdivided into two different models.

Standard equipment on the SLE-1 includes 17-inch alloy wheels, foglights, tinted windows, heated mirrors, an integrated driver-side blind-spot mirror, cruise control, a power height-adjustable driver seat, a sliding and reclining backseat, tilt-and-telescoping steering wheel, an auto-dimming rearview mirror, a rearview camera, OnStar, Bluetooth phone connectivity and a six-speaker sound system with a touchscreen interface, a CD player, satellite radio, auxiliary audio jack and an iPod/USB interface.

The SLE-2 adds roof rails, automatic climate control, an eight-way power driver seat with power lumbar adjustment, a leather-wrapped steering wheel, upgraded cloth upholstery, Bluetooth and a premium eight-speaker Pioneer audio system. The available Convenience package adds heated front seats and remote ignition.

Move up to the SLT-1 and you get those Convenience package items plus perforated leather upholstery. The SLT-2 takes things a step further with 18-inch chrome-clad wheels, rear parking sensors, a power liftgate (with adjustable maximum height), chrome exterior trim, driver seat memory functions and a sunroof (optional separately on the SLE-2 and SLT-1).

Options vary by trim level and include a 3.0-liter V6, 19-inch chrome-clad wheels, a trailer towing package, a voice-controlled navigation system (with digital music storage) and a dual-screen rear video entertainment system. A lane departure warning and forward collision alert system is also available on SLT-2 models.

Performance & mpg

Every 2012 GMC Terrain comes standard with a 2.4-liter four-cylinder engine that puts out 182 horsepower and 172 pound-feet of torque. Towing capacity with this powertrain is 1,500 pounds.

In performance testing, a front-wheel-drive, four-cylinder Terrain went from zero to 60 mph in 9.4 seconds -- on the slow end for the class. EPA estimated fuel economy stands at 22 mpg city/32 mpg highway and 26 mpg combined with front-wheel drive and 20/29/23 mpg with all-wheel drive. These numbers are impressive, but after extensive testing, we failed to see such thriftiness from the four-cylinder Terrain -- especially on the highway.

Optional on SLE-2 and SLT models is a 3.0-liter V6 that produces 264 hp and 222 lb-ft of torque. Front-wheel-drive and a six-speed automatic transmission are also standard, while all-wheel drive is an option. With this engine, towing capacity jumps to a respectable 3,500 pounds.

In performance testing, a V6-powered all-wheel-drive Terrain went from a standstill to 60 mph in 8.3 seconds, which is also on the slow side. EPA-estimated fuel economy is 17 mpg city/25 mpg highway and 20 mpg combined with front-wheel drive and 17/24/20 with all-wheel drive.

Safety

The 2012 GMC Terrain comes standard with antilock brakes, stability and traction control, front-seat side-impact airbags, side curtain airbags, a rearview camera and OnStar. In Edmunds brake testing, a four-cylinder Terrain came to a stop from 60 mph in 121 feet. A heavier V6 model did the same task in 127 feet. Both results are good for the segment.

In government crash tests, the Terrain earned an overall score of four stars (out of five), along with four stars in frontal impacts and five stars in side impacts. The Insurance Institute for Highway Safety gave the Terrain its best possible rating of "Good" in its frontal-offset, side and roof strength tests.

Driving

The 2012 GMC Terrain's standard four-cylinder engine should suit most buyers' needs nicely. Even though the real-world fuel economy numbers don't measure up to the official EPA estimates, this is still one of the most fuel-efficient crossover SUVs out there. Just the same, the V6 is probably a wiser choice for drivers who regularly haul around a full load of people, cargo and/or a trailer.

One of the most noticeable qualities of the driving experience is how hushed the cabin is, giving the interior an upscale feel. The ride quality is also quite comfortable, with a substantial feel reminiscent of a bigger SUV, though be aware that bigger wheels make things rougher. Handling is unremarkable and the steering feels a bit numb. In other words, the Terrain is not the most responsive or agile compact crossover but it does manage to feel solid and competent on the road.

Interior

For a brand that touts its hard-working truck roots, GMC designers have done a remarkable job of giving the Terrain a decidedly classy interior. The style is sleek and modern, and that look is complemented by a number of high-tech standard features including the now-standard 7-inch touchscreen audio interface and rearview camera display. Unfortunately the dash's abundance of tightly grouped buttons can be hard to sort out with a quick glance.

The passenger cabin gets high marks in the comfort category, especially in back where the rear seat both slides and reclines. Families with growing kids will appreciate the extra legroom and comfort it provides. There's a trade-off here, though, as cargo room shrinks dramatically when you slide the seat all the way back. Setting that seat in the middle of its track is a good compromise, with enough legroom for kids and a family vacation's worth of stuff. However, the Terrain can't quite match more utilitarian rivals like the Honda CR-V or Toyota RAV4 for maximum space. Fold the GMC's rear seatbacks down and you get 63.7 cubic feet of cargo room, which is decent, but about 9 cubic feet less than you'll find in those rival crossovers.
