Per your response, each of the three times it stalled out, it was at low speeds, once in reverse and twice when driving forward from a stopping position. We picked up the car today from the dealership and they could not "duplicate" the problem after driving it about 100 miles after they "reprogrammed" the computer software....although the computer software said everything was correct and up to date; but the Service Manager thought that updating it should still probably fix the problem. He said three other Equinoxes came in recently with the same problems and supposedly they corrected them with the computer update.
Thanks again!
Has anyone heard of this? The start up sound is worse than ever and a care with approximately 7000 miles on it should not have had this many problems.
If it's low speed stalling...Either while driving at a low speed (like <20ish) or while accelerating from a stop... Many of us have had this issue with the engine start-up noise. Be as persistent as you can to have them change the actuators, solenoids, and do a software update. This has worked so far for others, including me, and for those that have had this specific repair, we are all still problem free, one of us is going on 4 weeks now with no problems. I'm on week 3. You can also refer them to PI0496- this refers to an intermittent check engine light with poor driveability issues. (rough idle, possible stalling) this bulletin covers a very specific build date range, however, it would be a reference point for the solenoids and software update.
IMPORTANT: if they are not willing to try the actuators, solenoids, and software update, I would request that they have a GM engineer come out to look at it and that you will settle for nothing less. Odds are, you qualify to file lemon law now, and the way it sounds for your car, this repair would help a lot.
Oil pump might be a suggestion from your dealer, it will NOT help unless your tested oil pressure is way off.
Good luck and keep us posted. It seems to be a problem that GM is "currently investigating."
They replaced two actuated solenoid valves during one service call. They reprogrammed the computer during 2 service calls. This was to fix the stalling problem.
The replaced the timing chain and water pump to fix the ratcheting noise at start up.
My radio will also lock up with no functionality. When Bluetooth is activated and the end call button is pushed the radio works again.
The dash compartment is also broken, that is an easy fix because it is not linked up to the stupid computer system.
I am having these reoccuring issues because the dealer can never verify the issue onsite. August 8th markes the 4th time the car as been in for service. After all of the repairs the car still stalls, makes a ratcheting sound when started and has a bad radio.
I have 7500 miles on the thing and it only gets 22MPG. I have all highway miles. It is supposed to get 32 MPG or around that. I would be happy with 27 or 28, but 22? Come on!
I'm being persistant and am sending a letter to GM officers Mary Barra. Can anyone say LEMON!!!
I informed them this morning that I notified GM Repurchasing of the problems I'm incurring and may not buy this car if it can't get fixed. All I want is to be able to get into a car and drive without a worry. I haven't had that pleasure since April of this year. How long have you had your Nox? Thanks for your reply. It has reassured me that they are on the right track.
2011 EQX 6000ish miles purchased off the truck 3 months ago. Engine rattle, stalling, sway whining when turning. Took it in yesterday, got it back today and repairs were Computer Error code #PO11 Intake Cam position performance, updated and programmed new calibrations for ECM. Also cam actuator and solenoid had debris ans was cleaned.
So far so good...
Timing chain and water pump will probably not fix the start-up noise. (sorry) Have not heard of the water pump fix though. But others have had the timing chain replaced and it did not work. For those of us on another forum, equinoxforum.net, that have had the start-up noise....for one or two of us it has also progressed to the stalling problem where you start the car, put it into gear, start pressing the gas and the car stalls. There are now THREE of us that have all had the same repair (after countless failed repair attempts) and it has worked for all three of us going on four weeks now. This is VERY SUBSTANTIAL, considering how many people have gone through so many failed repair attempts thus far.
This repair that we've all had- solenoids replaced (intake and exhaust), actuators replaced, software updated, and oil change. It may or may not require more than one oil change. I can not stress enough that all 4 of those things are vital. There have been people that have had 3 of those done and it didn't work.
The dealer can't verify- record the start-up noise on your phone, as a video. That will catch their attention. And whatever you do, don't delete that video, keep it handy, just in case.
Get your car up to speed of about 65, then reset the average mileage on the dash. Set the cruise to 65 for about 5 miles, then tell me what the average mileage is. This is how I get my numbers, I do not factor in the mileage of getting up to speed.
As for the radio, they might have to replace the whole unit, but I've heard of it being done for a different kind of problem, it's covered under warranty at least.
The dash compartment- unfortunately it seems that the spring is weak and sometimes breaks. There have been several people posting about this, but it's an easy repair, only takes a few minutes. Also covered under warranty, of course. Definitely the least of your worries.
I'm sorry it's been such a pain for you. If they haven't done all 4 things in the repair, I would have them do it ASAP. And I would demand that they have a GM Engineer come out and look at your car. They can do that, you know. Tell them you're considering filing for lemon law and that you demand a GM Engineer come out and work on it. And a reminder: replace solenoids, replace actuators, oil and filter change, computer update. And make them keep it for several test drives. My dealer did 130 miles total of test drives, just as a reference for you I guess. Good luck.
Do you happen to know your build date? There is a bulletin, PI0496, for an intermittent check engine light with codes P0011 and P0014. My light came on 3 different times before my repair. The first two times, only the P0011 code showed, and the third time it was both P0011 and P0014. This bulletin applies specifically to build dates between 2/17/2011 and 6/6/2011. (My light would turn off by itself after a few hours, or the next day) These codes are related to poor driveability (stalling) and rough idle. I only noticed a rough idle when the light was on. BUT, the bulletin states that there are certain software updates that need to be done, and if the car has over 250 miles (yours is well past that), then they should also replace the solenoids.
Since you also have the start-up engine noise, I would say you get the following repair. This is what was done to my car and it's been smooth sailing for 3+ weeks now. At first, they just replaced the actuators and the noise came back 3 weeks later.
The "good" repair- replace solenoids, replace actuators, update software, oil and filter change. All four should be done.
There are now 3 people that have had this same repair and we have all been back to normal for 3-4 weeks now, which is HUGE compared to the past failed repairs that have been tried.

I had the engine noise and intermittent check engine light with stalling and rough idle. Someone else had the start-up noise and stalling, but no check engine light, and they did the same repair as the "good" one I listed above. It's probably your best bet, to be honest. The stalling is the same, start car, put into gear, apply gas, and that's when it stalls.
My return trip from work is about 12 miles of mixed driving and previously I had gotten an average of 25 mpg this time after the repair it was 29.
Paired shaft phasing off of a common drive should not be so tough to get right. I am an engineer who works in manufacturing and there are plenty of machines I work with every day that are mechanically similar. Maybe it is beyond GM's current engineering expertise to get this right.
From what I know, there haven't been any accidents with the stalling, but there HAVE been close calls. If you're pulling into traffic when it stalls, it is definitely a safety hazard. They need to acknowledge this and recall sooner than later.
For loaner/rentals- if they keep your car overnight at ALL, YES, you ARE covered by warranty to have a rental or loaner. It seems t hat many dealers are being stubborn about that, which makes no sense. I believe somewhere in the warranty it even says that if they are keeping your car longer than TWO HOURS, you are covered for a rental. Not totally sure on that though.
NEVER accept payments/onstar, ANYTHING to end your case with BBB. They are trying to buy you out, and if problems arise later down the line, even next month, this may hurt you. TURN DOWN all of their offers. Demand an oil change. If they won't give you one, I would pay for one yourself.
I didn't notice this until I tried to open it at home and the entire unit almost came out of the dash.
I email and they tell me to take it to the local dealership and get it fixed.
Local dealership orders the part and tells me to come back today.
I go in and find out this part is on backorder and could take weeks. WTF a brand new car and simple interior parts are stuck on backorder!!! I am now pissed.
