    Good afternoon,

    This is a great question! At this time, I don't have much information on the 2013 Terrain Denali that will be out later this year. I will keep an eye out for any updates, though, and will get back if I near anything!

    I purchased my Terrain almost a year ago. I've had the same problems almost the whole time. When I start it, it sounds like I'm holding the key on, a grinding/rattling noise. Also, while idling, occasionally the RPM's dip below 600 and it sounds like it is going to stall. It used to stall every morning but they replaced the camshaft position solenoid valves.

    My concern is what these issues are doing to the vehicle long term. I've contacted both GM and BBB and no one is familiar with the issues. I've had it in for service numerous times but they haven't been able to "duplicate" the problem. I was just curious if anyone else has had similar issues. Thanks!

    Hello sundohio,

    You stated in your post that you contacted GM; did you receive a case number from us (71-**********)? We'd be happy to check in on the case if you like.

    Hi Sarah,

    I do have a case number and someone I'm communicating with. I recently found a group of people who are having a similar problem. They had a video of it and I sent it to the tech @ the dealership. I'm hoping they can diagnose the problem from it. Thanks.

    No progress yet. The dealership told me that GM didn't have a "fix" for this problem. And they didn't know what to do about it. I guess that means I need to proceed via the Lemon Law.
  • I just bought my new 2012 GMC Terrain last month. I have less than 1,500 miles on it. Last week while pulling out of a drive-thru, the StabiliTrak warning light came on along with the message to Service StabiliTrak. I immediately pulled over and read the Owner's Manual. I turned the engine off, waited 15 seconds, and restarted the engine which cleared the message and the warning light. Since then it has happened three more times, each time as I was making a turn. It clears whenever I restart the engine. I called OnStar to have them run a diagnostic, and everything came back fine. I have the 2.4L engine, FWD. I have contacted my dealership and will take it in sometime next week to have it looked at. Has anyone else had this problem?

    Before I go crazy, can someone tell me if the 4-CYL comes in the SLT-2?? I'm able to build it on gmc.com that way, but I haven't been able to locate any.

    GMC completely lied about the gas mileage. For those who are looking for a new car and want great gas mileage, this is NOT the car you want. We chose the 4 cyl option and trust me, the only way this car would get 22 mpg city and 32 mpg highway would be if it was being towed, with its engine off, by a Honda CRV. Even then I suspect the Terrain would find a way to burn gas somehow.

    My wife had a new V6 Ford Escape prior and we got rid of it because we loved the safety and technology of the newer Terrain. However, what really sold it for us was the advertised mpg. We have now had this car for 6 months and I want to know something. How can a car that advertises a 26 combined in reality get an actual 21.5 combined????? My wife does not speed and we leave the ECO always on. I will tell you why, the city mileage probably gets 10 mpg.....if that. What a joke.

    GMC, I know your company was headed for the brink of extinction and the tax payers had to save you. I am happy that everything worked out and we Americans were able to keep money and jobs in the U.S. However, this does not give you the right to lie to the people who ultimately bailed you so you could boost car sales and avoid bankruptcy.

    When the class action lawsuit comes, and it will definitely be coming, we will be joining in. However, after the lawyers get their 75+% of the cut, that should leave each of us owners with a $1000 payout....not nearly enough to compensate us for the extra $1500 in gas per year versus what you sold us on. What a major disappointment.
  • Autobots - I have similar disappointment with my wife's 2011 Terrain. We traded in a 2008 Mountaineer after I convinced my wife that we needed to downsize & take advantage of the better fuel economy. Most of my wife's driving is in-town and our 6 cylinder is supposed to get 17 MPG. I believe the best MPG we have seen on in-town driving is 13...WHAT A LET DOWN. I called GMC & was told that they were aware of problems with the 4 & the 6; that they had a fix for the 4-cylinder and the engineers would be working on a fix for the 6. They also told me that once they had the fix that they would give owners $ for the extra fuel that they burned before the fix. You might want to ask about this fix (believe it was a fix on vehicle software.) No offense, but you probably won't benefit from a class action. There was a story on TV recently about a former lawyer in CA that filed a lawsuit for a Civic Hybrid that didn't get the advertised mileage. You might want to read about that on a website she has opened. I had a lemon and took my vehicle to the dealership for the same engine problem 4 times in the first year. The dealership never got the vehicle fixed. I found a law partnership that works these cases on a no recovery-no fee basis and they filed under the lemon law for me. Their fee is only paid by the manufacturer if they win. I have taken my wife's Terrain in 4 times for this fuel economy issue and nothing has been fixed.
  • I bought a 2010 4 cyl for a variety of reasons, but especially for the gas mileage. We live in Dallas which is relatively flat and my wife uses it for commuting and around town. We have never gotten close to 32 mpg on the highway and trust me, I've tried. The best we've ever gotten is about 28 mpg on the hwy. Around town in mixed driving we consistently get 22+mpg and in the last several months we are consistently getting around 26 mpg! My wife changed jobs and most of her driving is now slow rush hour type miles from stop and go to the 20 to 40 mph crawl. That has to be the difference. Overall, she loves the vehicle. I hate the front seat. Can never find a comfortable position (basic cloth seats), but she loves it so I'm happy!

    Also, we just took it to the dealer for some recall warranty work and they replaced a lot! The big item was the high pressure fuel injector. They also replaced the timing belt, some hoses and a bunch of sensors on the timing belt. It used to be very noisy at idle, but now it's as quiet as any other vehicle we've had. We'll see if it improves the gas mileage.

    I'll take 26 mpg which is much better than any other vehicle we've had but it would have been nice to get even close to the advertised 32 mpg on the highway. I read a car mag review where they had the Terrain for a long period of time. The "professional" car guy had the same gripes. Overall he loved the vehicle but could not get close to the advertised mpg and he wrote that he tried everything. He too maxed out at about 28 mpg.

    So, potential buyers, its a great overall vehicle but beware of the advertised mpg!

    I have a 2012 Terrain SLE1 4cyl with 400 miles on it. When trying to start the vehicle, it turns over briefly and then stalls. It takes up to 6 tries to finally start and stay running. This scenario has occurred many times in the short time I have owned the suv. It could be the first start of the morning or after it has been driven. I waited until I filled up with a new tank of gas, just in case that was the problem, before making an appointment with the dealer. The vehicle goes in on Monday, 4/9/12. I also called GMC, they opened a file for me, and will contact the dealer to follow up on the issue. It is embarrassing for me and for GMC to have a new vehicle still with temporary plates on it failing to start while in public areas. My son stays away from the car until it starts and then discreetly gets in to avoid embarrassment. So much for taking pride in driving a brand new car. I am desperately hoping that a plausible and permanent fix can be quickly made.

    In city driving be it mixed freeway or surface streets, the average I have seen in my Terrain and Equinox are both around 22/24 mpg in non eco mode and sometimes using manual shifting.

    Please be aware that these cars are not going to get advertised EPA mileage figures and if you expect that you are in for a rude shock. It doesn't mean that they are not great cars but you have to be realistic about how you drive and where you drive. I recently did 2500 miles in 2 weeks primarily interstate driving but also 2 lane road driving at speeds from 75mph to 25mph with a/c on and averaged 25+ mpg overall. While not EPA estimates, it was good for what and how I drove.

    Hope this helps with some real world results.
  • I have the same problem. About 3000 miles on the Terrain bought in December and it started. At this point dealer has tried twice to fix. Last time was today, I did not make it home before I got the same service message. They are getting me a loaner car (which tolls the Lemon Law for out of service time periods) and will try to fix it as soon as they get another loaner in. Needless to say I would NEVER have bought this SUV if I knew I would be chasing this service message so soon. Dealer is stumped and I am looking at Lemon laws. I don't know if this is a big issue or not but obviously this kills the market value of the vehicle to keep giving you and error message around the transmission.

    Good morning texas_trader,

    I'm sorry to see that you are encountering these concerns on your new Terrain. Have you worked with Customer Service on this yet? If you would like to open a service request with us, please email socialmedia@gm.com (include your name/Edmunds username, phone and address, last 8 of your VIN and current mileage, and the name of your dealership).

    All the best,
    Sarah

  • Just took a 600 mile round trip from Dallas to East Texas and back. Cruised along with traffic at about 65 mph plus some stop and go and farm to market highways. Still only got 26.5 mpg, even after all the warranty work I just had done! This was mostly flat to rolling hills driving, primarily on an interstate. You just can't get much more than 26 mpg with the 4 cylinder! Otherwise comfortable and a good highway cruiser with plenty of pep for a 4 banger.

    Picked my Terrain up from the dealer today. They had called to say they started the car close to 70 times and could not produce the stall condition. When I arrived I discovered they had driven it 63 miles! The car didn't have to be driven anywhere to produce this problem let alone 63 miles. I was not happy at all. I was able to produce the condition in their presence on the 4th try. Does something smell awfully fishy here? We had a bit of a debate and they suggested I take the car somewhere else. I called the GM Customer Service District Specialist of NY/NJ and she said I needed to bring the car to another dealership to have them look at. Honestly, if this car goes through "another day at a GM dealership" like it just did, it's not going to survive. I'm writing a letter to GM Corporate Offices and will cope with the trouble starting the vehicle. I can only hope the day arrives where the car fails to start altogether and I can call On-Star and have it towed/repaired. Hopefully I am not stranded somewhere uninviting.

    the fact that dealer could not reproduce problem in 63 tries and you reproduced it in 4 tries is not necessarily fishy - it's exactly how insidious software bugs behave. the trigger could have something to do with the exact speed/cadence at which you turn the ignition-key, anything obscure like that. anything is possible in cartoons and software.
    The GM engineers will know how to fix it via "technical assistance center" which dealership should call. Keep escalating the issue until it is resolved - or trade the car if/when you decide it's time - demand super-favorable trade-in, like 0% depreciation - dealership/GM should offer this to you - ask for that option and get a vehicle that makes you happy!
    If you decide to help GM chase the problem, the service department may *need* you to demonstrate the problem to them. If you make the issue occur while the vehicle has "data-logger" connected to OBD, hopefully that will provide the info necessary to diagnose/fix. Also the dealer can loan this 'data-logger' device to you for days/weeks at a time. best wishes....

    I have seen elsewhere some owners get close to advertised EPA highway milage, but they drive in the 55-60 MPH range which pretty closely matchs the EPA highway test.
