2011 Chevy Equinox Problems



  • CMESMILE32, I know exactly how you feel. I purchased my NOX on April 6, 2011. I have just under 8000 miles on it right now and it has been in the shop every other week since June 23rd. I have had the exact same parts replaced that you are referencing. The stalling part of the problem has been fixed as far as I can tell, but there is an aweful noise when I start the car. This is an intermittent problem. I have opened a case with GM regarding this issue. I encourage you to do the same. My car does this on occasion when I start it, See the link. I also filed claims with the BBB and wrote letters to several top executives within GM, posted a nasty message on their Facebook page and sent a letter to the General Manager of the dealership I purchased the car from. I'm finally getting some progress going.

    Something is not right with the EPA's mpg calculation for the 2.4L Equinox. By comparison, a Kia Sportage, also equipped with a 2.4L, 176HP engine, is also rated @ 22MPG city, 32 highway. However, the Sportage has a better drag coefficient than the Equinox, and weighs 643 FEWER pounds (3186 vs. 3829). And they supposedly get the same mileage? I don't think so. My advice would be for the "buyer beware" if you're counting on the Equinox to deliver the stated MPG! And the ethical thing for GM to do would be to have the vehicle retested by the EPA, using "real world driving" parameters. It's appalling that customers are buying this vehicle, with fuel economy being a top priority, and being let down in this way-not a recipe for winning repeat business. To say nothing about the host of other problems buyers posting to this forum are experiencing! I'm glad I made this discovery while I'm still evaluating vehicles for purchase.
  • NICK082579-Thank you for writing back, I feel like I am stuck in GM hell and can not get out, I am getting the run around from GM customer service so bad, they keep telling me they have escalated my case to be evaluated for a buy back and I they need the district service manager to look at my vehicle. But, the DSM has been nowhere to be found since last Monday! In the mean time, my vehicle is unsafe to drive and the dealership I bought it from will not give me a rental because they need the DSM to approve it! I got so disgusted with the dealership and service dept, I consulted an atty and he said it qualified under the Lemon Law. But, that could drag out 45 days, I need a reliable vehicle. I have tried so hard to be nice about this and asked the dealer about trading, he wanted $2500 to trade (mine has 3000 miles). I am so disgusted with GM. Will you please let me know how your case progresses? GM needs to take responsibility for these defective vehicles.
  • I would love to know the outcome of your situation with GM because it is a mirror image of what I am experiencing right now in NC. The GM customer service has been horrible and I feel like I am getting nowhere, I also want my vehicle replaced and want to be credited for my payments. If you have any advice, please share. GM needs to step up and be responsible, this stalling issue is going to cause someone to be seriously hurt. Thank you!
  • Tracy02-I am having the same issues with my 2011 Equinox and am getting nowhere with GM. I have been through all of the replacement parts and updates, the vehicle has 3000 miles on it and has stalled on me twice with my 2 young children in it. I am so scared we are going to get in a serious accident from this defective vehicle. It qualifies under the Lemon Law and I guess we are going to have to pursue that since GM will not step up and take responsibility. Have you had any luck on a buy back with GM? I would appreciate any insight you have from your dealings with GM, our dealer and service dept have been horrible.
  • grassk-Have you made any progress with GM? I am having the same problems with the vehicle stalling and noone can figure it out, all of the major engine parts have been changed and the vehicle only has 3000 miles. I am beyond fed up with GM customer service. The case was "escalated" to initiate a buy back over a week ago and noone can find the district service manager to get the ball rolling. I have talked to an atty and of course this qualifies under the Lemon Law, but I was hoping GM would step up and be responsible. I would love to know if you have made any progress.

    After making the noise 3 times right after the last fix, I went and got an oil change. It has not made the noise in about 2 weeks. I have decided to take a wait and see position on this since it has not done it agin since the oil change.
  • Thank you sumr616 for reply.. I finally got my 1st recall letter from GM Chevie yesterday. Called dealer told him recall stated to replace valves. He said he would call GM Tues (holiday Mon.) still questioning whether he needs to replace valves & then I read sentence to him again. Then I called 800# on letter and talked to Nino for an hour. He called dealership while I waited on hold. Nino said someone from GM-Chevie will be calling me on Tues.(holiday Mon.) also. I now have a file and he gave me file # and mentioned a possible trade for a 6 cycl. Eq. adding that my car was now considered a "used" car "if" they did do what he suggested. I quickly told him I considered my car a "new car" (I wish I had said a "lemon car"). I have not even started questioning some of other things that I read on here(ie: metal shreds in oil filter etc) I am not even sure if I want another Eq. now. I am 60 and usually keep a car til it dies of old age. I still have my 03 Tahoe 300,000 m.- my husband bought me bfore he died that yr., but bought Eq. because it is hard to climb up in Tahoe now and minor problms--AND I thought Eq. would be better for gas m.-boy was i wrong. In 2005 popo threw out stopsticks behind me and guy they were chasing (on I40) hit me at 130mph. my neck was not even sore the next day. (I had slowed to 40mph when he hit me)-he stopped in frt. of me & popo shot him. They had been chasing him on I40 for an hour. He had no ins. and stolen car and dead. My no fault ins. fixed my Tahoe. -maybe i will just start driving my ole safe Tahoe instead of worrying about stall-outs in my new Eq. -lol. Just thought I would add that because not ALL Chevies are bad. !!! My 1st car was a 68 camaro-still have it and drive it some. I will keep ya'll posted on my Eq. THANK u Edmonds again! and Thank u God for computers!
  • Please be weary of the latest recall, we have been dealing with ongoing Equinox issues on our 2011 for the past month, the "recall" was done to my vehicle before I ever had the paper in the mail and it only made my vehicle run worse, it stalled on me in the middle of intersection the very next day! We have had the timing tensioner, timing chain, cam shaft automaters, valves and solenoids all replaced on a vehicle with 3000 miles! It has been in the shop more than on the road, after being so disgusted with GM customer service and a service dept that could care less, we have had no choice but to get an attorney to file a lemon law case. After the stall out the day after the "recall", the service department "reprogrammed" the transmission, the fuel mileage has dropped drastically since they did that, every time they touch it, the performance is worse. We are waiting to see what action they take now that we have an official lemon!
  • We picked up our vehicle on 6/2/2011. From the time we took delivery we have had problems with hesitation and very poor gas mileage. We were told by our sales person that the hestitation was normal. Starting at about 4800 miles we began experiencing stalling. We now have our vehicle in for the 4th time for repair. It was in 2 wks prior in which they performed the most recent recall for this problem. We will now be going through the process of persuing the lemon law. My question is does anyone know if the 6 cylinder engine has had similiar problems or has this been an issue with just the 4 cylinder?
  • Good question Denise! I would like to know about 6 cyl. also because Chev. rep. and dealer talking about trading my 4 for a 6., but implied I would have to add some $ to trade because mine is "used" car. No way...had a no win conversation with Chev rep. yesterday-they called & said they had done all they were required which is only updated computer on car. Said my 15 mpg. was in "range" with what i should be getting. *^%*!!!! Going back to dealer today with my recall letter! Calling lawyer if i get nowhere. Engine really hesitating bad and stalled again in Reverse. P.S ...hearing that high pitched noise for about 1 min. after I cut car some people have posted. Think that is least of worries right now.

    I've been watching these threads for about a year now looking for any compelling reasons to consider a 2010/11/12 Equinox purchase. From the information posted here the 2.4L seems has valve timing issues which don't seem prevalent on the 3.0L V6.

    Engine design details are not easy to find but the following quotes from available internet sources gives background information which you may find helpful:-

    Equinox2.4L DI details
    The new 2.4L DI engine delivers an estimated 180 horsepower (134 kW) @ 6700 rpm and 172 lb.-ft. of torque (232 Nm) @4900 rpm. It uses technology based on GM's other four-cylinder direct injection applications, but with unique features designed for its specific application. This includes an 11.4:1 compression ratio that helps build power, slightly dished pistons that increase combustion efficiency and injectors with an application-specific flow rate.

    GM benchmarked the best fuel system and noise attenuation products to provide customers with quiet operation.

    3.0L DI details
    The new 3.0L DI engine is a variant of GM's family of high-feature DOHC V-6 engines that also includes GM's 3.6L DI engine in the Cadillac CTS – an engine named to Ward's AutoWorld's 2009 "Ten Best Engines" list for North America, for the second consecutive year.

    The 3.0L is rated at an estimated 255 horsepower (187 kW) and 214 lb.-ft. of torque (290 Nm), for an impressive power-to-displacement ratio of 85 hp per liter. (Output will vary by model.) The 3.0L DI features an isolated fuel injector system that reduces the direct injection high-pressure fuel system pulses for quieter operation. Rubber isolators are used with the fuel rail to eliminate metal-to-metal contact that would otherwise transmit noise and vibration from the high-pressure fuel system.

    Along with direct injection technology, both the 3.0L DI and 2.4L DI engines use variable valve timing to optimize power and fuel efficiency across the rpm band, as well as reduce emissions.

    There was a little problem with the 3.0-liter V6 that was the base-level engine for the 2010 LaCrosse, at the model's launch. The 3.0-liter, which is simply a smaller-displacement version of the 3.6-liter V6 that was also available, provided slightly worse highway fuel economy than the much-more satisfyingly torquey 3.6.

    That left us wondering what exactly was the point to the exercise. GM was apparently thinking the same thing, so for 2011, the 3.0-liter will be stripped from the LaCrosse's spec sheet. The new entry-level motor which begins production soon is the 182-horsepower 2.4-liter four cylinder (look for a drive story on that version soon). That engine brings 19 mpg in the city and 30 on the highway compared to the 3.0-liter LaCrosse's 17/26 mpg fuel efficiency. But it will clearly make the base LaCrosse a slower car than before. The LaCrosse will still be available with the 3.6-liter.

    But the under-performing 3.0-liter isn't completely dead. The Chevrolet Equinox and GMC Terrain will still offer the small V6 as their upgrade motors and the Cadillac CTS line will still use it as its base motor.
  • We now have 13500 on our 2011 Equinox 4 cyl. and have not had any issues with the engine. Is there a common thread about these issues? What type of oil or gas is used?
  • Yes!! I purchased mine in Sept. 2011 - this has happened twice!

    I just got it back and they tell me it is the "Camshaft regulator".
  • :lemon: I own a 2011 Equinox.

    Loved the look of the car... just wondering if I made a bad choice.

    Two times since I bought this car, it has been in the shop. I know some may crucify me for saying this... but, I owned a Kia prior to this, and I loved that car. But, I felt bad for not buying "American"..... so, I bought the Chevy (though my Equinox was actually made in Canada - go figure).

    1st time - running rough for a week or so, engine light comes on, stalls, and then to the shop it goes. The dealership blames me for not checking my oil at every fuel up. The car was almost two quarts low. So, when I tell them that you should not have to check oil in a NEW car, they come back with "well, this car might burn more oil than other vehicles" Right! I told them I have owned several new vehicles, and NEVER have I had to add oil between oil changes to a NEW car.... They finally admitted the prep people might not have checked the oil prior to me picking it up... who knows?

    2nd time - running rough for a week or so, making a grinding noise (sometimes) when I start it, engine light comes on, stalls. Dealership gets an ear full......

    Is the "Camshaft regulator"......

    Honestly, IMO when you purchase a new car, you expect it to be RELIABLE. I am very disappointed in this car.

    Nice looking car, bad interior (mesh seats).... wish I would have gotten the leather, runs rough all the time, loud knocking engine (sounds like an old beater), bad gas mileage (I drove mostly city), and TERRIBLE in the winter!

    If I could trade this crate in and not take a beating I would do it... But, I am at the mercy of the dealership. Seems like they market the heck out of this car, and yet they slap it together...

    Any thoughts?
  • Don't know what happened but here's my message:
    Hope this will help in startinig your Noxs! Don't just get in and start the vehicle. First off, get in turn the key and WAIT for all the dash lights to go out (engine light will stay on). After they all go out, start the car. This has reset the computer. This has eliminated the knocking and noise when I've started my Nox. I've been doing this for over two weeks now and it has helped! This is just like having a diesel and waiting for the glow plugs to heat before starting the vehicle. I hope this helps you all! I was given this info by a brother who got it from a Harley mechanic. The new Harleys have to be started this way to reset the computers. Makes since. Like I said, I haven't experienced any problems in the last two weeks.
    As for the mileage, it still sucks! I was down to 12.1mpg on my last tank. I don't get it. I use 76 gas and from the same station most of the time. I was told that Chevron is the best of the best now. I will get rid of this tank and fill up with Chevron to see if it helps any. Will keep you informed. Let me know if this helps anyone. Good luck everyone!!
  • I had the same problems with my 2011 equinox. I had a lot of stuff replaced and it no longer stalls or check engine light come on. But it was hell. Then after I get it back, I get a recall notice in the mail about the same issues. If you haven't gotten the recall notice, you need to contact a local dealer. They need to replace several items to correct this problem. The downshifting still happens, it is just a crappy engine. Mine actually slows down when going DOWN hill!
  • The drive line is engineered to down shift as the car slows on a down grade while reducing speed; this is an excellent feature that assits slowing the vehical; similar to the engine brake on commercial trucks.
  • We are the owners of a 2011 Equinox that is a major LEMON! Ours has 3500 miles on it and we are in the midst of trying to get a buyback through our attorney. This vehicle has been a nightmare, we have posted several times about our summer of hell with the Equinox. It started with the loud start up noise, went on to need a heat shield cover, timing chain, timing tensioner, cam shaft automaters, solenoids, transmission reprogramming and started to stall. We got nowhere with GM customer service and nowhere with the sorry dealership/service dept, so we had no choice but to contact an attorney, the vehicle is not safe. The gas mileage has sucked from day 1 and the dealer kept telling us it was because of the amount of ethanol in the gas....premium Shell gas did not make a difference. This has got to be the sorriest engine GM has ever made. My husbands GMC 2500 diesel truck is getting better fuel mileage.
  • I am still BITTER about our Equinox. I previously posted all of our problems over the summer. Our brand new car first died about 10 days after we owned it!! The problems continued .....
    I could not drive it with my infant and toddler without fear of getting into a crash with the crazy drivers where I live.

    GM was useless, full of lies, and clearly not interested in helping. A lawyer wanted the case to pursue the lemon law but we did not want to wait however long it would have taken to pursue it and then lose money anyway (they would have deducted the mileage off of it) and I was NOT taking another equinox.

    How old is your car, what is the mileage. We only had a couple hundred miles and were able to trade it in. We were very fortunate that we only lost a little more than 500.00.'s crap that we had to do it but it was the right decision for us. What were we thinking buying a Chevy after they were bailed out? Hell, they probably put in a refurbished engine.

    We are thrilled with our new car. The only thing I miss about the nox is the space and Onstar.

    Good luck.
  • I drive an older Equinox and am normally very happy with the mpg. However, this summer in NY State got some fuel from at least two different stations that made my car struggle up hills and suck lots of fuel. After putting in better gas the problem went away.

    Additional information on the 2.4 L Equinox engine from website below. -4l-ecotec/

    From personal experience I know that aluminum engines need to be carefully warmed up at every start before driving away. Also, engine oil is used to cool and lubricate variable valve timing mechanisms and must be meticulously clean. Some manufacturers insist on oil changes every 3 months or 3,750 miles, whichever occurs first.

    These are sophisticated GM engines designed to compete with the "world engines" developed jointly by Mitsubishi, Daimler Chrysler and Hyundai which have been in production since 2005

    Quote -

    ""The new Ecotec 2.4L engine includes technology that provides a number of benefits. “Direct injection was designed into the 2.4L to boost fuel efficiency and for refined power,” said Chris Meagher, chief engineer for Ecotec engines. “The variable valve timing system is tuned to work in tandem with direct injection to achieve optimum fuel economy and lower emissions. The engine achieves a respectable 182 horsepower and 172 lb-ft of torque, which makes for a pleasing customer driving experience.”

    With direct injection, fuel is sprayed directly into the engine cylinder, where it is mixed with air. As the fuel vaporizes in the cylinder, the air and fuel mixture is cooled. This enables the use of a higher compression ratio, which improves engine efficiency and performance. Direct injection also reduces cold-start hydrocarbon emissions by up to 25 percent.

    The Ecotec 2.4L engine is an all-aluminum, dual overhead cam, four-valve engine with forged steel connecting rods and oil spray cooling for reduced friction and noise. In all models, the engine is mated to a highly efficient six-speed automatic transmission. ""

    End of Quote

    Is it possible that valve timing issues could result in lube oil dilution (as has been reported on this site) due to mistimed fuel injection?

  • :lemon: Well, I am posting AGAIN.

    My 2011 Equinox broke down for a second time in 4 days! Third time since I purchased the car.

    Took it to the dealer, and they say they replaced the "cam shaft regulators" for the second time in four days. C'mom, seriously. Who are they kidding. Translation: "We don't know what in the heck is wrong with this car, and will replace anything we can just to get you off our backs" The owner of the dealership told me to "wait for it to happen a 4th time, and they would support me pursuing a buyback". I was going to do it until I thought about it.

    Why should I have to drive this NEW vehicle around, and wait for it to break down. Not happening. So, I took the necessary steps for buyback.

    I am not going to bash all Equinox vehicles. I loved this car when I purchased it. Maybe I just have a lemon? Just IMO - this is the biggest pile of junk I have ever purchased. But, I bought this new to avoid mechanical problems and to have a reliable vehicle which this is NOT.

    I do appreciate the advice about getting in and waiting for the lights before starting the vehicle. I hate to be negative here.... but, why should this vehicle require any special treatment as far as starting? Do any other Chevy's require this? Is this in the manual?

    I am not sure what is going to happen with it.... but, even if I have to take somewhat of a loss, I am not sure I would own another Chevy. IMO I am the customer, and as such... Chevy needs to make this right. They did not hold up to their end of the contract.
  • I just read your post. I'm on my second Nox as I too had a :lemon: ! I had less than 2500 miles on it before it went bye, bye. I live in CA and while driving on the freeway one day, the darn thing quit on me. Luckily, I was able to pull off the freeway and get the car restarted. It kept dying on me here and there and finally, I had had enough. I lived at the dealer more than at home! I know how you feel.
    I've had trouble with starting my second Nox but in waiting for the computer to reset before I start has made a tremendous difference. It doesn't knock or make a awful noise. I've been told that most dealers don't know about this and they should! Yes, I agree that Chevy should say something about it but as far as I'm concerned, they don't even know that you should wait for the computer to reset before starting. It makes since. You have to wait for your computer to reboot when you turn your computer on so it makes since.
    Good luck. If you do go through the repurchasing process, FYI don't let the dealer and GM charge you a fee!!! Yes, they both charge. Good luck!!
    #234 of 235 2012 Equinox 1-LT by chevy48
    Sep 14, 2011 (9:59 am)

    Just wanted to let everyone know that I had to put my new equinox, 3-weeks old with 400 mile in the shop. I went to go to work and started it up and on came a light for the engine malfunction. I needed to get to work and decided I would drive it anyway. I backed out of my garage and put the car in drive and notice some hesitation and continued down the road and just felt that it was not responding well when I stepped on the gas pedal. I decided to turn around, when I slowed to turn the vehicle around it stalled. I restared and it was very sluggish but managed to get it back inot my drive way. My husband came out and when he went to move it back into the garage it stalled, he restarted and stepped on the gas pedal firmly to keep it from stalling. So as of right now, I do not know what it wrong with it and will keep everyone up to date when I find out from the dealership service dept. :(

    This should start a 2012 Equinox string.
    Shame, you would think these issues would be sorted out after three years in production!!
    Is it the 2.4L or 3.0L engine?
  • This is the 2.4.with 400 miles on it and have only had it for 3 weeks. It is a shame I really love this equinox. I researched it for about 6months. I wished I would have seen all of this information prior to purchasing. I hope no one else with the 2012 has this issue and it is just a fluke. Maybe wishful thinking though.
    Do you have one?
  • Received a call from the service dept. Today, said my vehicle was done and ready for pickup. They said they replaced the Solenoid valve camshaft sensors (2). Went in signed the paperwork and got my keys. Checked the vehicle on the outside for any damage that may have occurred while my vehicle was in there possession( you never know what can happen), and everything looked good. Open the door put the key in the ignition and started her up. Everything seem to be ok, NO engine malfunction light on. Woo dee we are in business....wrong!!!put the car in reverse backed it up and then put it into fact, it stalled 3x. Back into the service department and spoke with the guy in charge. He was shocked and came out to see...As if I wasn't telling the truth. Well they are trying again to fix it. Called me up and said it is the camshaft actuator. They replaced the camshaft sensor only. So that is my continuing un happy situation. They said the vehicle will be done tomorrow. I will keep everyone updated.
  • Here is the latest on our Lemon drama, since we have an attorney, GM wanted our vehicle back in for a final repair attempt, we took it back in and left it overnight. The service manager stated they could not duplicate the stalling or hesitation between 20-30mph, they supposedly drove it on and off while they had it. We now have just over 4000 miles. They contacted an "engineer" that suggested they change the camshaft actuators, well, that had been done a month ago. So, we picked it up and by the time I got home, I had an email from the dealership thanking me for using their service department, but the email also stated in BOLD letters that my ENGINE NEEDED REPAIR! I can not wait to see how they explain this one to the attorney!
