2010 Chevy Equinox Problems



  • Hi rag top
    you hit the nail on the head...that's exactly what they dealership said.
    The dealership stated GM has to reconfigure the spark plug...something like that it's
    sparking too soon. They also said that I should be using better grade gas, I switched over to a better grade at mobil and I noticed huge difference. My car also bucks at low speeds and feels hesitant and down shifts wierdly I mentioned all that to the dealership
    and he said "I bet it's all related"????????
  • Hi Kenb8

    Your situation sounds like mine...don't really know for sure but there are alot
    of similarities. I switched over to prem. gas hoping that it would help and I have to say
    it did BUT I think GM should fix this issue regardless.
    I have been told several times from GM& the dealership that a new software will be implemented, GM had said to me after several I mean several trips to the dealer
    that it should be ready near or at the end of September and what I am hearing is the
    spark plug is misfiring, not sure why it's misfiring all I know is that's what it is
    and the software should be updated soon. Now I am wondering my car bucks at low speeds my car feels hesitant and it down shifts awful I wonder if it's all realted the dealership had said it most likely all is related to the spark plug BUT I am no mechanic.
  • Have any of you folks tried ethanol free gas that is available in some markets? There are some concerns as to the effect increasing amounts of ethanol will have on engines.
  • I am not sure If I can get gas around here without any ethanol,
    have never come across
  • Well, after driving my Equinox for over a year, the wiper blades are shot and need to be replaced. I checked the local auto parts store, but the 2010 Equinox uses special wiper blades that you can only get at the dealer. I wasn't thrilled with that, but went down to the dealer to buy them. They didn't have them in stock, and when they tried to order them, they found out that they could get the rear blade and the front passenger side blade, but the driver's side blade is on national backorder. (Of course, that's the one that's critical.) I've now been waiting over a month, and there is still no time estimate on when it might come in.

    I haven't gotten too worked up about the initial quality issues, the warantee repair work that I needed, and the lingering issues such as pinging and sticky steering. But now I can't even get new wiper blades?? The parts guy was like "what's the big deal, its just a wiper blade".

    Not being able to see when its raining is a big deal. This is a safety issue for me, and that's where I draw the line. Last I checked, GM is still building Equinox's - and I assume they're putting wiper blades on them. Apparently GM is so concerned with keeping the production line running that they can't divert a few of those parts to their existing customers who need them. I'm officially no longer an Equinox fan.

    My advice for anyone else who needs new blades but can't get them: RainX washer fluid. It's not a replacement for new blades, but it really helps out by beading up the water.
  • Go to They have several varieties of blades for the 2010 Nox.

    Thanks - I'll give them a try. I went to three different local parts stores and was told that none of the aftermarket blades have an adapter for the Equinox blade mounting system. Of course the Chevy parts guy told me that there were no blades other than the GM replacement part that would fit.

    BTW - have you changed your rear blade yet? I spent a long time trying to figure out how to remove the old one. Then the dealer service manager tried for about 20 minutes. Turns out it just snaps out and back in - there is no release button or latch. The problem is being able to grab it to pull it out since the plastic blade cover is in the way and you can't see or even feel what you are doing. Eventually, the service manager used a hook shaped tool to get underneath and just pried it out. Fortunately, he didn't charge me for his time.

    Hello Ragtop262,
    Do you currently have a case number for the parts delay? If so, what is the case number? Thank you,
    Mariah GM Customer Service
  • No, I don't have a case number. I've just been following up with the dealer's parts department every week or so. Called again yesterday, and they told me they would follow up with GM one more time and call me right back with an estimate as to when the part would be available. They never called back, so with advice from someone else on this forum I was able to locate and purchase aftermarket blades. Thank you for your concern, but there's no need for any further follow up as far as my issue. (Although other owners may be having the same problem, and may still need help.)

    Thanks again wallyuwl,

    I used the part numbers from the Rock Auto website to find the correct blades at a local parts store. I can confirm that the Anco Profile A17M (Passenger side) and A24M (Drivers side) blades do fit, even though they may not be listed in the parts store catalog or computer for the 2010 Equinox.

    The Anco Profile blades appear to be the exact same blade as the original, except for the mount. Since they are universal fit, you have to use an adapter (included in the package) to fit the pushbutton style mount on the Equinox.

    Those new wipers were sure nice during my two hour drive in the rain this morning. :)

    Hello Ragtop262,
    Just wanted to make sure that you did get some assistance with your concern. Thank you for getting back to me.

  • I'm having the exact same problem. I placed an order for wiper blades with my local GM dealer, and was told all three are on back-order. Yesterday I got an email that they had the left side in (drivers) but the rest are stilled back ordered. I've been trying to get blades for months now.

    Really concernening that GM can not stock wiper blades for their own cars. They are a very important safety device.

    I guess I will check into the after-market part you posted about.
  • "Sticky Steering"....I'm so glad I found this site and others experiencing similar problems. I think my wife thought I was driving drunk when I first noticed the steering issue. You have to physically jolt the steering wheel to keep the vehicle from tracking straight down the highway. At highway speed, this is extremely dangerous. I did take my Equinox into the dealership and they're replacing the steering module and powersteering pump (appointment on 9/20/10). Will post again if I notice a change. This is the 3rd time I've had to take our new Equinox into the dealership and am extremely disappointed in GM. The cruise control has problems downshifting at highway speed, we've had problems with the airbag light continuously coming on, gas mileage not even close to what is advertised, and then the radio/air control module problem that was recalled. Cannot wait to get rid of this vehicle.
  • My 2010 Equinox has stalled 3 times, last time was with 18 wheeler coming down the road...not fun. Dealer says no ck engine codes to trace and really cannot re-create the problem. I mentioned the ecm relay replacement on your car and that did not seem to register as something they needed to do. Any more advice out there?
  • gmcustsvcgmcustsvc Posts: 4,251
    Hello Hwytime,
    Have you taken the vehicle to a different dealership for a second opinion? Does any codes come up on the DIC when this does occur? Thank you,
    Mariah GM Customer Service
  • My 2010 Equinox finally stalled this morning on the way to work. For the past yeay...whenever i have come to a stop, and the car was warmed up, it would almost stall. The RPMs would drop...the car would shake, and then it would fight back and run again. It would do this every 10 seconds. It is almost as if the idle RPMs have been set too low. This happens mostly in ECO mode, with the A/C off...but I did have it happen with ECO off. finally stalled when I was wating at a stop sign. The RPMs tried to fight back, then it died.

    I am going over to my dealer nwo to see what is going on. I only have 17,100 km on the car. THis seems to be an issue with this engine.
  • I have a NOX with just under 10k, mine seems to do the downshift thing at 34 mph and has since it was delivered last November. When I took it back to the dealer for the first oil change in April 2010 there was the problem of the center console had gone dead and the heat and cooling controls were dead, the car was still driveable. The dealer reprogramed some module, there was a recall on this, but he preformed 3 other service bulletins and not a problem since. I like the NOX real well.
  • OK ........ WHERE"S THE UPDATE???????
    it's almost the end of September.
  • "My car also bucks at low speeds and feels hesitant and down shifts wierdly I mentioned all that to the dealership
    and he said "I bet it's all related"???????? "

    No, it isn't all related. The engine issues (pinging/knocking), and downshifting issues, are different.
  • Yeah, I noticed the exact same thing on my 2011. The actual temperature outside can go up 10 degrees and
    the display stays on the original temperature that was shown at start up early that morning. If I drive down the road a couple miles it gradually climbs but still isn't accurate. The display gradually went up to 75 degrees, but it was really 85 outside!

    This is my story so far: (4 cyl. 2010 equinox)

    When starting the engine (not always) I can hear a short sharp noise coming from the engine
    Dealer service department solution:
    - CAM phasres replaced and R&R the CAM actuator solenoid checked for debris (no debris found)
    - CAM positioning actuator (exhaust) replaced and checked for debris
    After that the noise was gone!

    Two months later:
    - When accelerating on uphill from 0 mph, between 1500 and 2000 rpm I can hear a repetitive clatter (knocking) noise coming from the engine (left side). The noise is louder when the AC is ON.
    - When starting the engine (not always) I can hear a short sharp noise coming from the engine. Same problem as two months before. I think came back at the same time when I noticed the other problem.

    First visit at the dealership service: They drove the car and said that they couldn't hear any noise. I got in the car with one of the technicians and after the test drive he agreed that there is a noise coming from the engine area and suggested replacing the AC pump, although I knew this was not the problem.

    AC pump replaced, I took the car and when I got home I heard the same noise again.

    Went back and the technician suggested top engine cleaning.

    Cleaning completed, and according by the service manager they drove the car and the noise was gone.

    BUT when I took my car and went home the problem was still there.

    Back again and when I got there they were upset because I was back with the same problem and almost blame me for the problem. We got in the car (me and the service "manager") and drove the car so he can see that I'm not the liar. He remained without words.
    After that he said: "I will call GM to find out what is the problem but now there is nothing I can do"
    Next day :
    The service manager said that GM is working on updating a software to recalibrate the spark plug which sounds good (for the pinging noise), but I don't think that that kind of noise at certain rpm can came from the spark plugs.

    The engine works differently (worse) than 6 months ago, sounds like a diesel engine, is much louder and mpg is getting worse (was pretty good 6 months ago).
    I have been having trouble with hard shifts between 30 and 40 mph.

    It becomes more frustrating.
    Saying sorry all the time is not helping at all

    I also hear a sharp noise sometimes like the starter is scraping or something.

    I have posted on this one twice. Took it to the dealer and they reflashed the ECU worked for about 2 weeks and started doing it again. I have decided that if GM does not come up with a fix before March of 2011 I am getting rid of my Equinox. Better hurry up GM or this will be my last GM purchase ever!!!!!! My father retired from GM so considering getting a GM rep. involved soon.
  • Wonder what GM is saying to this dealership service department that is (allegedly) changing parts left and right, THEN calling GM "to find out what the problem is".

    As for the "sharp noise" when starting the engine, have you tried starting the car with someone underneath or looking over the top of the engine while turning the key? Have you tried changing the motor oil and running it through a screen mesh (much like what is done to catch a kidney stone)? Sounds like a metal to metal noise of some kind. Misaligned starter motors can cause a metallic shriek at startup when they engage the flywheel improperly, but I doubt that would be your problem on a brand new vehicle. I think this happens on a used vehicle where the starter motor has been replaced but a required shim plate was left off.

    I'd be screen-filtering the motor oil to see if there are any fragments in there from the factory.

    I am new on this board, but happy to have found it. I have had my 2010 Equinox LT2 for about 6 months and basically like it a lot. My biggest complaint is the jerky transmission and a hesitation problem. I notice it the most when I'm going reasonably fast (over 40) and then have to brake, like when traffic slows down. During the braking, if I then have the opportunity to accelerate again, the transmission often will hesitate for 1-2 seconds, and then the car bucks forward. This also happens, for instance, when I'm on a highway and want to change lanes if I get behind a slow driver. I slow down a little, and when I go to accelerate to change lanes, it hesitates and then bucks. The hesitation has almost caused an accident for me when it hesitated as I was attempting to change lanes. At first I thought that this hesitation problem was "just how the car is," but after reading this forum, I'm thinking that this is not normal. Have others experienced this? Is there something Chevy can do about it? I have not taken the car for anything but an oil change.

    Another transmission thing: I also find that when accelerating up a highway hill at a reasonably high speed (60+) the transmission whines really loudly until I release my foot from the gas.
  • They supposedly rolled out the "Fix" for the knock, but consequently there induced more problems as well. Since updating the cals on the ECM in my 2010 equinox, I know am getting "Service Power Steering Soon" displayed in the DIC, and my "ECON" switch is indicating a high voltage situation which in turn sets a DTC and the CE light comes on. Up until this point I was really satisfied with my 2010 Equinox, but I think when and if its fixed this time, I will drive it directly from the Chevy lot to the KIA dealership. I am really fed up with Government Motors and there lack of customer focus.
  • Yes - I as well have experienced the "bucking" problem with the transmission.
  • When was this update released, I was just at the dealership yesterday for the "spark knock" update and they said that nothing had come out yet, but that it should be soon?
  • I just picked up my car from the dealership where I had them look into why my car was stallling. They replaced the exhaust acctuator and so far it is running a bit better. Will keep everyone informed....
  • Call from a GM customer specialist (more like a middleman) today:

    "Spark knock" update in the next 6 - 8 weeks

    If you ask me I don't think that something will happen before New Year
  • Last fall they approved a new transmission calibration in late Sept. I got it from a GM engineer literally the day after it was approved. It started to go into production vehicled supposedly the week following that. It was supposed to be available to dealers by late October. If you look at the technical service bulletins, this particular TSB (for the tranny cal) is dated as being available on Jan 1, 2010, about two months after it was supposed to be. That is, of course, if the date is right. I have no way to know if it is or not.

    I'm not worried about the knock sensor update, though I'll probably get it when it comes out. It is fine using premium, and Shell V-Power has way more detergents in it to keep injectors and such clean. So I'm OK paying the extra $4.50 per tank for that. Replacing bad injectors (which is necessary withing 100k miles if you use bad gas) is very expensive (often $1000 or more).

    What I REALLY want is for them to come out with another tranny calibration that makes the thing drive normally. The six speed in the Malibu, for example, is silky smooth, but it has a normal calibration. The downshifting characteristics, (including the "bucking", as some have called it, at times while downshifting) are the only complaints I have about this vehicle.
