GMC Terrain



  • We also found that all the SLT2's were the V6. We special ordered one with the I4. It took about seven weeks. We have had it exactly one month today, and we love it.

    I had a 2008 GMC Acadia and it did this all the time, the dealership could never duplicate the problem, after it happend a few times my braking would get wierd when it would come on. Always went out on it's own after a few minutes, I recorded it being on one time, but they would never do anything about it. Always the same thing stabilitrak light would come on and flash a warning to have it checked. My Acadia even once stalled on me when I went to go thru an intersection. I'm disappointed to read these problems with another GMC vehicle. I don't think i'll purchase one again:(

    this first/stabiltrack-message problem is almost certainly an intermittent diagnostic failure of a wheel-speed-sensor. when it's intermittent like that it really is nothing to worry about (my 2005 GM vehicle has done it intermittently for all its 7 years, mostly in hot weather. dealership can never replicate it and often the code is 'cleared' by the time they read the OBD.) if it occurs and concerns you, find a place to safely stop/restart car and restart and it should re-enable the stabiltrak . you can get your own OBD reader tool for $29 and read the detailed code causing the message, if you like.

    stalling is another problem altogether, much worse problem. should never happen with a modern automatic transmission vehicle. only occurred once? that might be one time too many for me as a car-buyer. totally unacceptable.

    I have the same issues with my 2011 Terrain. I have an appt to take it into the dealership today. Last year it completely stalled on me 3x while leaving a parking garage. I took it in to get serviced and they changed the camshaft and solenoid valves as well.
    I still have issues with the loud rattling noise when it starts up and the rough idyling once its in park. The noise is very bad. Friends of mine even commented on it various times.
    In addition, while I am stopped at a light or stop sign it feels like it is going to stall out.
    When I asked the dealership if they were having any of these issues with Terrains, they said no. So I am trying to be proactive and research on my own. Before purchasing the Terrain I had a Toyota Corolla and went through hell with it to try and get it fixed. I would of never imagined I would be back in the same situation so soon!
    Do you happen to have a copy of the video you spoke of? I would love to be able to show the dealership.

    Have you had any luck recently with the fix? And have you started the process for the lemon law?
  • mwells7mwells7 Posts: 3
    I'm trying to be proactive regarding the issues I'm having with my Terrain because what I'm reading is not giving me much hope. Have you received any information about your Lemon Law claim? Does the lawyer feel it will get resolved?

    Fortunately, I have not had those kind of problems...just BAD gas mileage. I tell everyone I can "Stay away from this vehicle - it is a gas hog!" False advertising - I don't care if EPA says 32 mpg - it doesn't get it.

    My Toyota Camry Hybrid gets what the sticker stays - 39-41 mpg.

    This sounds interesting - wonder if they will actually contact us for a "fix?"

    My 4 cyclinder could use some help - gas mileage is horrendous - and I drive very conservatively.

    I hope that your appointment today goes well, mwells7!
    Looking forward to any updates,

    Sorry everyone isn't getting the gas mileage they wanted, but the culprit here in the EPA. It's the EPA who estimates mileage, and the manufacturers simply post that result. Further, if you read below the BIG NUMBERS, you'll see there is actually a broad range of mileage that you can expect to get. Just another gubmint scam.

    I own a 2010 Terrain have had it since January of 2010. I would like to mention for me in the city of Chicago the fuel consumption has been what is expected I have the 2.4lt. 4cyl. and get an average of 26mpg mix city and hwy and for a long road trip to Nashville got 36 Mpg and that was my calculation not what the car displays. I was very impressed.
    Now the problem I do have with the car is that like everyone else I get a rough idle and it has turned off on me a couple of times at red lights.
    The cam has been replaced, oil pump, timing belt (chain), and fuel pump. after all that I still get a rough Idle and a rattling sound the dealer told me, that is how that engine should sound. It is louder than any 4 cyl diesel.
    Who do I need to talk to for help? It is not normal for a car at 25k miles have this much work done to it.

    Good morning bishop07,

    I'm sorry to see that your Terrain has a rough idle, and that the different repairs you listed haven't helped to resolve this. If we can check in on this situation with your dealership for you, please send us the following information to your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your involved dealership.

    Kind regards,
    GM Customer Service

    Appreciate your response. Minor correction to your stats - the dealer drove my car 63 miles and supposedly started it successfully 70 times. They didn't have to drive it anywhere to reproduce this problem. They used my car as a taxi and not for the purpose of replicating the problem I clearly reported. Since picking up my Terrain from this "service" appointment I have been keeping a log of every time I start the car. I record each start whether it is successful or not. From 4/11/2012 through 5/17/2012 I have attempted to start my Terrain 115 times. It failed to start on the first try 26 times. Do you still believe the dealer started the car successfully 70 times in a row? There is a problem and GM has no idea how to fix it. As for escalating the issue, I tried that - I called and wrote to GM. As a response, GM Customer Support closed the file that they opened for me in April. In their world the issue is dead. Now that I have documented 5 weeks of data I will try another GMC dealership. I have little faith it will be corrected - we'll see.

    Brutal. My 2012 is 200 miles old and has stranded me twice. 2 new fuel pumps and still no successful solutions. Here comes an engineer to the dealership to try to solve my problem. I want out from under this sniper...gmc wants to keep fixing it.... Go Gm!

    Good morning rtick,

    Have you opened a case (71-**********) with our Customer Assistance Center on this as of yet? If not, we'd be happy to look into this further with you if you wanted to send the following information to your name/Edmunds username, phone and address, the last 8 digits of your VIN and current mileage, and the name of your involved dealership.

    Kind regards,
    GM Customer Service

    hi devs1... if dealership does not inspire confidence, it is fine to try another one, but of course can be difficult to travel to a different one sometimes.
    a failure-to-start that strands you is a glaring 'drivability problem', so if that's the case then after a certain # of days-in-shop/attempts-to-fix, the vehicle can be administratively lemon-lawed in many states. maybe your state has lemon-law?
    either way, i believe the adage 'do not attribute to malice what can be explained by ignorance' and that a well-intentioned 'taxi driver' like the courtesy-driver or parts-driver for the dealership might not notice an occurrence of fail-to-start, especially if started fine with an immediate-retry. a technician specifically looking for starting problems would not make that mistake, however.

    btw, are you using the lowest recommended octane? (87 near sea level). premium fuel is harder to ignite by definition - it makes for harder starting, and provides zero benefit for most engines, probably including the terrain's.
  • We bought a 2012 GMC Terrain on August 1, 2012. We love it but the Stabilty Track Service light comes on and stays on after about 10 minutes of driving. We have tried clearing it but it just keeps coming back on. My husband is taking it in to the dealership tomorrow morning. The manual says it is safe to drive but I find this annoying. I hope we can fix this.
  • Congratulations on your new Terrain! That's so exciting! However, we're sorry that you already are having to make a trip in to get a warning light checked out. Please keep us posted on how everything goes in the morning!
    Sarah, GM Customer Service
  • I love the 2012 Terrain I've been driving since February. However we've had a teenager problem where I work and I have need of a locking gas cap or locking door to the cap. There is not one made for any year of the Terrain models according to my local service department and we're told there is no after market one that will fit them either, by our local parts dealers. This is a Huge problem for me. As expensive as this vehicle was, a simple lock shouldn't be an obstacle for GMC. When will this problem be addressed?
  • ray80ray80 Posts: 1,233
    Stant has not yet updated their web site to include 2012 model but they list two locking gas caps for 2010 and 2011 Terrain (reg and E85, most likely just color of cap differance). You might get your local parts place do do a try before you buy on one of these if they stock them.
