2012 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

Review

I bought my Terrain in June 2012. The first year was good nothing out of the ordinary with regular maintenance. As the end of the second year approached I started having random engine light, Stabili Trak messages appearing. I am on my 4th service call with the dealership. The last time 2 months ago they kept my vehicle for one week and found nothing they could repair. The first time they diagnosed a carbon build-up which they cleaned for a fee, the second time nothing could be found, the 3rd time nothing and today I could not drive much above 55 mph on the highway. The car was sluggish and seemed to have no pick-up. I felt like it would stall any minute. I did stall eventually. Frustrated!!!

Don't buy a 2012-2014 Terrain

My 2012 Terrain has 38,000 miles on the odometer and uses 1 qt of oil every 2000 miles. The Dealer that falls within GM's specs????? No wonder they had to be bailed out. I get 21.5 mpg overall with the 4 cyl/auto and that is below the EPA city rating. The navigation had to be replaced plus the transmission needed replacement at 32,000 miles.

Air bags failed to deploy

Ran off road, hit a tree... received a concussion as head "bounced" off steering wheel. If bags had deployed, would not have been knocked out via striking head and perhaps I could have avoided massive damage to vehicle and 2 days in hospital.

Terrain Problems

2012 GMC Terrain SLE-1 4dr SUV AWD (2.4L 4cyl 6A)

Review

I bought my new terrain in May 2012 after just having it a short time the navigation screen would go very dim and then bright. I took it to dealership more than once, they did not know why or how to fix it after trying several times. I contacted GMC corporate about the problem. It is still not fixed. I stopped taking it to dealership because if they can't fix it why take it in. Now I have another problem. My ck engine light coming on. Took it to dealership, it is a random misfire, they don't know why or how to fix it. It's in there for 2nd time in one wk I now have the gen mgr involved- I refuse to get stuck with a lemon. I have a loaner vehicle

2012 GMC Terrain SLT-1 4dr SUV AWD (2.4L 4cyl 6A)

Review

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

BAD BAD FUEL ECONOMY

Review

Do not "presume" that you will get anywhere near the sticker mpg with your Terrain. You won't. Our sticker showed 22-32 and we get 23.8. GMC is not "playing fair" by having EPA conduct the fuel tests so that lawsuits are avoided. Apparantly the only way to get close to 32 mpg is by driving between 48-60mph on a flat or slightly sloping downward road...If you are plagued by poor fuel economy with your Terrain, I urge you to call GMC and your GMC dealer and voice your complaint!

LOVE IT except for the transmission jerks.

Review

We've had our Terrain for 6 months. Always have been a loyal GM customer. The Terrain stole our hearts when we decided to purchase a new vehicle. Its sharp. Inside and out. LOVE the interior and all the cool features. There is one problem......transmission slips/jerks. I have 9,000 miles on it. When I took it into the dealership they had a "transmission" specialist come out to talk to me. I explained the jerking/slipping and he urged me to take him for a drive. The entire time instead of observing the ride he explained to me that it was just the "engine recharging" because of the eco motor. I call BS. It seems to be getting worse. Anyone else had this issue??

When purchasing this car last year the mileage was listed at 18-26 mpg. It barely gets 19 mpg, and so far its never met 20 mpg's. In this day and age its terrible that we cant be getting at least 25 mpg's
