GMC Terrain



  • I don't think I can take it back. According to my loan papers it states there is a "No Cooling Down" once I sign I can't change my mind. I just dropped it of at our local Certified Dealer - he didn't seemed surprised at all. I'm just heart broken over the issues, this truly was my dream vehicle - I hope it all works out. Thanks for the advice but I'm afraid I'm in for it now. :(
  • GMC Service says the high pressure fuel pump needs replaced thus causing all the problems. Apparently fuel is mixing with the oil?? I'm picking it up tomorrow after work. Fingers crossed!
  • I purchased a 2012 Terrain just over a year ago. Starting mid December 2012 it has been in the shop 4 times for the same issue without identifying what is causing it. The vehicle misfires causing the vehicle to shake and flash the CEL and the Service Stabilitrak Light. The misfires have happened on different cylinders. So far 4 of the 6 coils have been replaced. Dealership told me they were denied by GM to replace all of the coils at the same time. With the current trend the vehicle will be in the shop again in a week. I have been in contact with GM service representatives, or shall I say lack of. I have called my representative and the main line over 7 times the past week and have not received a call back. GM has horrible customer service and does not care about anything other then themselves. This was my first american car and has also been the only car that has been to the shop. So disappointed. I am taking action under the Motor Vehicle Warranty Enforcement Act to get a refund. I wouldn't even want to venture with replacement option of this act. I advice anyone else having these issues to do the same. Stop supporting a company that doesn't care about you after you purchase a vehicle. 711148526449

    Our apologies that Linda hasn't contacted you back yet, saschmitz (I looked up the file number provided in your post). I will add information from your post to the documentation in the case and let her know you're looking to hear back from her.

  • Sad to say after 2 weeks in the shop "again" after my last post I finally got my car back. Torque converter and drive train failure with 101,600 miles on it AFTER a rebuild 3 weeks prior due to broken wave plate. After contacting GM and my dealership did as well, my car now has a "new" " remanufactured" GM transmission!! Thankfully due to the amount of trouble and repairs I have had on this car and the transmission GM covered it! Only catch was a free 12mth 12,000 mile warranty or for $500 I could get a 36 month 100,000 mile warranty. I drive 120 miles a day to work round trip so I HAD to go for the 100,000 miles. Again luckily my dealership offered to pay 1/2 of the $500. I want to trade it off due to the fact I dont trust it anymore but I am almost $3000-$4000 upside down in my loan!! Can't do that! Still disappointed in this car but glad to see GM will stand behind their products. (For my case anyway). And kudos to my dealerships service department y Bob CLyse in Ironton Ohio. Next car will be from them only NOT a GMC!! Your service department is a big selling point for my car purchases and this one speaks volumes!!

    It is a disgusting vehicle - and GM does not care if you or anyone else has a problem.

    Good luck getting something back - I hope you can do it. I only wish I could have - but now am stuck with this terrible vehicle.

    I don't have an extended warranty - the non-American vehicles I have had just run without any issues. My Toyota Camry Hybrid has 94,000 miles; only replaced the tires! It just runs!
  • We are having the same problem with our 2010 4cyl. Terrain. Picked up terrain from service. Was told it was almost 4 qts low only after about 3.000 miles on oil change. was told we should check oil after each fuel addition. That is ridiculous. Oil had blown back into filter and other places. They said they replaced water pump shaft, timing chain. We had had the car for 3 years and this has not been a problem before. Our check engine light goes on and off intermittenly. we received a letter last week for an upgrade and was then told about checking oil. Why were we told this now,
  • ray80ray80 Posts: 1,643
    Sounds like you may have one of the bad engines. Since its a known problem with some you should be requesting an oil consumption test with dealer, little annoying but may result in getting a new engine (minus the oil problem). The letter is to address a change in oil life monitor program which is different then oil level ( The OLM doesn't have anything to do with amount of oil in engine)
  • gmcustsvcgmcustsvc Posts: 4,251

    Have you had your dealership do an oil consumption test on your vehicle? Let us know if you would like for us to check into anything for you by emailing us at (include your name and contact information, the last 8 digits of your VIN and mileage, and a summary of the situation).

  • We talked last night with someone from gm who was supposed to contact the dealership. We are just now requesting that they do a test.

    I have a 2010 I-4 with 86,000 miles on it,which has caused me a lot of grief. In the last 3 months it is now using oil, where it is going who knows. But I started checking the oil like we use to do in the old days. Four high pressure fuel pumps and some buck and jerking going down the highway at times, I don't think I will continue with GM either. Oh, I have never got near the gas mileage they say we were going to get either.
  • The dealership is saying you have to check your oil regularly at every fill-up and you can only use a certain grade oil like they are the only ones who can change it. Seems strange it has run for over two years with no problem, If they are saying this is normal, why didn't it do it the first two years. Last gm for us.
  • ray80ray80 Posts: 1,643
    I think if you weed through the posts that deal with the oil consumption problem (check the Equinox forum) you might find it takes some time before the problem develops if you have one of the bad engines, maybe 30 or 40 K miles. I don't know about every fill-up to check the oil, but I do check on regular basis, my vehicle, my job to make sure everything is good with it :)

    I don't know about every fill-up to check the oil

    It's a good habit to get into, and since I tend to go several weeks between fill-ups, I usually check the oil at the gas pump. If I'm on the road and filling up frequently, I'll skip a few checks. What I'm lazy about is checking the tire pressure (no TPMS on my older cars).

    The car is a piece of junk. I have a 2011 - purchased new. Already had some "camshaft actuator" quit - first car ever to stop on the road! And I have had lots of vehicles. Gas mileage - take it to Star Buick/GMC in Quakertown, PA. They did a consumption test on mine - said it get 38.9 mpg! I asked them where the rest of the gas is going???? The best it gets on the highway, perfect driving conditions - 27. I wrote a letter to the owner of this dealership - He owns several - never responded to me. I tell everyone I can about that dealership and about that vehicle. Bad news!

    Did you ever do an oil consumption test with your dealership, mike466? Let us know if this is something you were interested in - we can be reached via email at (include your name and contact information, the last 8 digits of your VIN and mileage, and a summary of the situation).

  • It is in the shop today because we were getting really bad fumes inside the car. Will see what they have to say. Not happy with their attitude.

    We have had our Terrain since Dec 2009 - it has been a total disappointment.

    Most recently in Dec 2012, oil was over 5 qts on the dipstick and it seemed very dirty, smelled like gas - SUV had been driven less than 3,000 miles after oil change. Took it to the dealership - they told us it was not over 5 qrts but it needed more oil - what they did not realize I took a few pictures of the dipstick before taking it in. After taking it back 2 times, they ended up replacing the fuel pump.

    Since we don't drive it much - now again 2,300 miles into it - the dipstick shows over 5 qts of oil and it is almost pure black. The SUV has only 34,000 miles.

    I have called GM Customer service in December and they really don't seem to know what is going on, to make things worse, I think the dealership was mad that we had called them instead of just going back to the dealership. Our friends have an Equinox and after 45,000 miles and similar issues with the fuel pump, GM finally put in a new engine.

    I requested the dealership to do a scope into the engine to see if there are any issues but they refuse, stating that they only do it on rare occasions.

    Please let me know if you have had similar issues. It is very tempting at this point just to get an attorney. Not to mention the loud noise the car makes and the awful shifting.
  • Had car in last of March for all these problems and today the Check Engine light came on again. VERY FRUSTRATED.
  • Had this in the last of March for oil problems, check engine light and fumes. Had timing belt and a lot of other stuff done. CHECK ENGINE LIGHT came back on tonight. VERY FRUSTRATED with GM.
  • I have the same terrain. I have had this car into the shop no less than 5 times for at least overnight repairs!!! Including an engine replacement after it sucked up 5 qts of oil in less than a month! this is unacceptable for a brand new automobile. I am scheduled to take the car in tomorrow night for a piston type noise that occurs from the start until I've gone through a few gear changes. As I told the service department I don't know if this is a coincidence of timing or if it has to due with the transmission. The cam shaft actuators have allso been replaced. I am TOTALLY fed up with this car. I ve had some sort of noise thought out almost the entire time I've owned this car. It has even had rust coming from the tail gate latch. After the "fixed"it, the latch is messed up causing it to cut into your hand when you open it. I like the drive, space and features but they are not worth the hassle I have had with this car. I will not be buying a gmc again!
  • I totally agree! I have the cam shaft actuator fix and had my whole engine replaced as well. As multiple "updates" that have been done that they said they would "work with me on" to get covered under my warranty! If its an update, it should be covered no matter how old! I have also had trouble with the service department fixing something only for something completely unrelated to be broken when I get it back, air conditioning, etc.
  • bwall2bwall2 Posts: 30
    I had to replace the cam shaft acuator as well - there have been noises which can not be explained - so, with 30k miles on (2011), it now gone! I traded it for a really nice Prius V - yes, smaller, but not that much! And, it is doing 47 mpg! Sticker says 42 but it is actually doing better! Of course the Terrain is suppose to 32 on highway - best we could every get was 27. I could not be happier! Check out the Prius V - it is larger than it looks.
  • bwall2bwall2 Posts: 30
    Interesting Sarah. I have a case number and a person who called me about 6 weeks ago - never called back! Terrible customer service from GM.

    Thankfully, I did not wait until I begin having all of these problems - there were unidentified noises and coughing coming with mine as well...30k and gone!


    P.S. If you are interested in my case number and who was suppose to call me back, let me know!
  • gmcustsvcgmcustsvc Posts: 4,251

  • I need help, I own a 2010 Terrain and have had nothing but problems , from camshaft actuator, full pumps, oil leaks, and power steering issues. Does anyone know how I can get ahold of a GMC rep, because my car dealership will not let me have access to that info. Please help me!!!!!!!

    May be time to start a class action suit. We just sent nasty letter
  • It is a terrible vehicle. We had a 2011; camshaft acuator went on this also. THE ONLY VEHICLE I HAVE EVER OWNED THAT STOPPED ON THE ROAD! A class action suit is so appropriate for this vehicle. Fortunately, after exactly 2 years of this miserable vehicle, (30,000 miles) we were able to get rid of it. The happiest day of my life - GM will do nothing for you. They have a real attitude - after we bailed them out, they believe they are untouchable.

    Class action suit would be great! Would love to be a part of that!
