I have owned a '10 4 cyl. Equinox since new, and it currently has 37K miles. I keep waiting for my car to fall apart, but I can honestly say that I have had zero issues with this vehicle. Have i been lucky, or am I more the typical owner,
Rit - You're not the typical owner if you've had your Nox 5 years and only put 37,000 miles on it! My God, you're barely using it. The average owner has around 75,000 miles on their vehicle by the 5-year mark.

Maybe you've had zero issues with your Nox because you really don't drive it much (or for any length of time to really put any stress on that timing chain)

Agreed - my typical trip is 300 miles, non-stop through the hills in NY, and the Pocono Mountains in PA. I have rarely been in BtB traffic, and don't do a lot of city driving. Although, today I stopped at 3 traffic lights, and the timing chain can still not be heard ! LOL

I bought this car for long/highway trips, I have a more fun car to drive for the rest of the time. To me, the Equinox is an "appliance" - but a very comfortable one at that.

Thanks for everyone's reply and experiences. This will help us make a decision on ordering an Equinox. I have compared it to other brands and their models as closely as possible.
All in all, as others here in the forum have said, the Equinox offers pretty much the best value, features, and size for the money in my opinion.

GMC Customer Service,

I need some assistance from you, to work with my dealer (Moore GMC in Danvers, MA).

I am experiencing excessive oil consumption in my 2010 GMC Terrain. At my most recent service appointment (September 8, 2014), the dealership added 3 quarts.
I traveled about 2,500 miles after that service appointment, and my ‘check engine’ light came on again. I checked my oil level, and had to add 2 quarts. After a few engine cycles, the light went off.

I notified the service manager via email ([email protected]) on October 29. No response.
I sent a fax to the service manager on November 4. No response.
I called the service manager on November 10. He told me he would “look into it and get back to me the next day”. Never heard back.
I called the service manager on November 20 and left a voicemail. No response.

I have been documenting my oil consumption (roughly one quart every 1,250 miles). My car has a very rough, irregular idle. It continues to run for a few seconds after I shut off the ignition.

I believe a repair of at least the piston rings should be covered under the 10 year / 120,000 mile extended protection program GMC recently announced (I received a letter in mid September 2014).

My GMC Terrain is a 2010, with the 4 cylinder engine. It currently has just over 70,000 miles.

Can you please speak to the dealership on my behalf.
They typically have offered me excellent service, but on this matter, they have given me the cold shoulder.

Not sure what the problem is, gmc has extended the warranty to 10 years 120,000 miles for these engine issues. I would complain to the dealership owner ,then find a different dealer.

In any case, it would be nice to know if the supplied GM Customer Care info did the poster any good or if they followed up with some other way to resolve their problem. It would help other future owners to know how things turn out when someone asks for help, rather than make one post, get what they want, and then disappear.

The dealer has to be the one to verify the oil usage. I brought it up while having my transmission rebuilt. They verified the level and topped it off. They told me to stop by when it was 1Qt low, where they verified the usage and then ordered the parts. Just had the repair done last week and it runs so much better.

If your dealer won't do this, find another dealer.

Just providing some follow-up...
a) GMC Customer Care contacted me (Nov 23) the day after I posted this message (Nov 22). She indicated that she would be following up with my dealer, and that I should hear from him in 24-48 hours.
b) I did not hear anything more until the dealer left me a voicemail on November 29. Not quite 24-48 hours, but I will cut them some slack on account of the Thanksgiving holiday (but still frustrated, because they hadn't responded to emails, faxes, or voicemails spanning back to October).
c) I have an appointment scheduled for Thursday for them to "investigate" the issue. They still aren't committing to actually doing the repair.
d) Someone suggested I get a new dealer:
- not so easy to do in the post-bankruptcy GM....they closed many of the dealerships, so my options within 25-50 miles is limited.
- this dealership has been doing all my servicing since I purchased the car in 2010. I am trying to give them the chance to make it right.
- yes, how they resolve this will have an impact on whether my next car is purchased from this dealer. However, after 4 consecutive GM cars, I'm beginning to think it's time to jettison GM. My last car (Aztek) didn't make it to 75K...My Terrain is limping at 70K. Meanwhile, my friends have Hyandui and Volvos with 100+K and no issues.

Yeah, seems you're having a rough run with GM vehicles. And if you've read other threads here, it seems you have the worst Terrain model. But, IMO, it's ridiculous to think Hyundai or Volvo have no trouble whatsoever.
But I definitely agree with you - dump the dealership. If there's not another GM dealership conveniently nearby, no point in going out your way. Hope your next dealership offers better service and keeps in touch!
And your GM dealership would probably try to entice you with deals for a new vehicle, but I wouldn't listen. Poor service = lost customer. Mean it.

DESPITE HAVING TO INSTALL A NEW ENGINE, I AM SATISFIED WITH HOW GM HANDLED THIS ISSUE
My wife complained a week ago that her 2010 GMC Terrain (70,000 miles) was very noisy, sounded "like a diesel". I thought maybe it was a batch of bad gas, the 10% ethanol taking it's toll after a couple years, or perhaps the recent cold spell (it got down into low teens in mid Nov). Thankfully she wasn't driving it Thanksgiving week since she flew home to see her folks, so I scheduled it into the dealer right before the holiday. They had asked if I had any warning lights or messages -- NO. I also had recently received the "Excessive Oil Consumption" letter from GM. Wednesday morning, as soon as the service writer heard the engine idle, he said it sounded like something having to do with the timing chain. They told me later that day it was 2 quarts low on oil & only a couple thousand miles since last oil change, so it was definitely losing oil (but I saw no evidence of this on my garage floor, nor had it ever had high oil consumption as far as I could tell). Also told me they suspected a problem w/timing chain and it would be a serious repair, up to possibly including a new engine (at zero cost, no deductible). Got a call on Saturday morning to advise that the engine swap was necessary and had been completed on Friday. Turns out the timing chain guide had broken apart and bits & pieces of it were circulating through the engine (service notes show serious scoring inside the cylinder). Would not have gone much further without some breakdown (timing chain, oil loss, etc.) The only charge I had was for the oil change which apparently was done on the new engine (I would assume they ship crate engines dry, not sure why GM wouldn't pay for the oil, but I was happy to pay only $26 for a new engine!).

HAS ANYONE ELSE HAD A NEW 2.4L ENGINE INSTALLED? Any issues, concerns, or watch-outs after an engine swap? Do we know for certain that GM has fixed the timing chain guide / tensioner / etc. issues that caused all these problems in the first place? Just curious how others see this issue. Do you have any concerns with keeping your Terrain/Equinox long term? Are there other reliability issues we need to watch out for?

My wife had a new engine put in her 2011 Equinox in Early 2013. Approx 20k to 24k miles later it is back burning oil and the dealer has put it on the oil consumption test again.

Just completed the oil consumption test for my 2010 Equinox. 1 litre oil used in 2300km. GM spec is .946 litre for 3200km. I am in the excessive range. My previous unofficial personal results were worse than this. I averaged 1litre/1600km avg. I am quite sure the oil was over filled at the beginning of this test. It was above the top recommended level after I left the dealer but in the end the engine still used more than the spec from GM.
Brought results to dealer and oil was topped up (no charge for visit or added oil), result recorded and the test continues until oil is low again. They want an average usage over 2 intervals of adding oil.

Warrany coverage includes any fluids that are required due to the failure of a covered component (such as engine coolant when a leaking water pump is replaced). I can't believe the dealer charged you $26 for engine oil. New engines are shipped dry - without oil.

But - if you are happy- that is all that matters.

PS - Did the dealer charge you for the oil filter?

Following up...
Just got my 2010 2.4L Terrain back today.
GMC put a new (well, remanufactured) engine in it. No cost to me.
Service Report indicated "Crosshatch marks worn on sections of cylinders indicating out of round bores. Exhaust manifold cracked".
I knew that the excessive oil consumption was linked to scoring (zebra stripes) in the cylinders. However, I was a bit surprised that the exhaust manifold was cracked.
Does anyone know if those two conditions are commonly linked?
What might have caused the exhaust manifold to crack? Could it have been back pressure from the catalytic converter? If so, does this suggest that the oil combustion may have fouled the catalytic converter? Or did the exhaust manifold crack simply because of excess heat, or something else? Any speculation?
Anyhow, I think I'm happy (caveat: I've only driven 8 miles with my 'new' engine thusfar).

Mangeog.. your the 4th or 5th reported case now of a cracked manifold. I believe it is one of two issues.. one, the type of cast metal it is made out of.. meaning if it was made overseas.. they have very bad structures of the material. Two being in the design.. the placement of the previous cracks shown were in or at what seemed to be a seem of sorts. Would have loved to seen a photo of your manifold to compare to the others.

Went through the oil consumption test and at the end of it ( 3 visits to the dealer over a 5000 km period), my 2010 Equinox was using 2.5 times more oil than the spec. The dealer replaced the pistons, piston rings, high pressure fuel pump, timing chain, balance shaft chain and tensioner this week. They had my vehicle for 2 days and paid for a courtesy rental. No questions asked. They must have washed the engine as it looks brand new. Hopefully the problem is now resolved. I am pleased that GM acknowledged that they have an issue with the 4 cyl engines.

It wasn't just GM and it is not just 4 cylinder engines. It is the Direct Injection technology most car makers are still struggling with:

* * * *
Here is a link to an article that barely scratches the surface: * * * http://www.autoguide.com/auto-news/2012/12/should-you-buy-a-car-with-direct-injection.html


In GM's defense, these newly developed Direct Injection gasoline engines have technology that has been troublesome to adapt for all the car makers. Car makers have adopted this technology in response to increased pollution and efficiency demands placed upon them by the government. If you do some searches, you will find that Ford, BMW, MB, Honda, Toyota and others are continuing to have problems, but, like GM, also continue to make improvements and modifications to resolve DI compromises in engine operation and durability. For the most part, all of the major car makers, domestic and foreign, have had the same or similar issues, with failed fuel systems, durability issues, and reoccurring problems. . .. until the past 2 years or so.

What you have happened into by buying a 2010-12 Terrain or Equinox was to get in on the advent and learning curve of this new Direct Injection (DI) engine technology. Even accelerated wear and reliability testing by all the car makers did not catch all the issues that have arisen. So in closing, you would have likely had issues no matter what vehicle you purchased with a DI engine in the 2009 to 2013 time frame. And some car makers would not have covered what GM already has done for your vehicle repairs.

Well, I hope this helped a little with some perspective. Believe me, it is not agreeable to me either, to have to do so much research and consideration when buying a car. But these are the times we find ourselves in. Also today, it is imperative to learn and follow proper operation and maintenance items when owning a car. They are not as forgiving as what we were used to 10 or more years ago. Oil levels must be checked at every fuel fill up if not at least twice a month.
Well, I hope this gave a bit more insight. If not, best wishes down the road.

As I mentioned in an earlier post on this page GM replaced all the parts that are in the TSB for oil consumption and I am happy to say that my first oil change is coming due since the parts change and my engine has only used .25 litre of oil in 4400km plus the oil no longer smells of gasoline. Much better than the 3.6 litres used before parts changed.
Dealership was great and they never even charged me for topping up the oil or labour during the oil test.
