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

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.
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,

Today...it finally stalled when I was wating at a stop sign. The RPMs dropped...it 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.
it's almost the end of September.
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.
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!
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
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!
I also hear a sharp noise sometimes like the starter is scraping or something.
I have been having trouble with hard shifts between 30 and 40 mph
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.
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.
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.
"Spark knock" update in the next 6 - 8 weeks
If you ask me I don't think that something will happen before New Year
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.
Anyone with this problem ,fixed the car yet?Did the GM came with the software that they were talking about?Can some one please, reply with any advice or info.... Thanks.
I apologize that you are experiencing a concern with your vehicle. If you don't trust your dealerships opinion you could take it to another GM dealership for a second opinion. Thank you,

unofficially, according to my dealership the official update to the software for the misfiring spark is out in November. I had mine done because I had made so many complaints to the consumer action council here in my state and I think they wanted to shut me up and get rid of me. I have to say since I had the update done the noise is very, very, very minimal and I hardly notice, I think I may have heard a slight knock and I had also went back down using the lower grade fuel. I also have to add since the update was done it doesn't seem to down-shift as much and less bucking. We shall see
though I have not opened it up on the highway yet since I got my nox's back.
I have to bring mine back in November again for another update, since the update so far so good!
I had my update for the software, next update is in November
I went through the same hassles as you....keep on them :shades:
the official update is coming in November., maybe I was their guinea pig
I have too dealt with this same issue...I have been complaining and complaining and finally the dealership had just completed the "unofficial" software update for my nox.
The official update is due in November
*************UPDATE*************
had the software update done
so far so good...according to
the dealership the official
update is due NOW in November :confuse:
I think but I don't know for sure that others with a 6cyl have experienced tranny issues, I wonder if the 4cyl has the same tranny system as the 6cyl. I which I knew more in the car area.
I have an appoitment on Wed .oct.13 ,and I would like to have the phone nr. by that time ,my dealership workers dont want to listen to me so I want them to talk with your dealership to convince themself that are other people with this kind of problem.
Maybe they have 1800 nr.Thank you very much .
I posted the info..but it got deleted
edmunds site said all I can tell you is the name
of the dealership.
Commonwealth Motors, MA
Sorry I can't help you further
I'm also having issues with my audio quality. I can be driving with the radio turned off and I get static coming from the left channel speaks. During radio and music play sometimes the left channel will get static and then go in and out. I have had the speakers replaced but the issue keeps coming up and my dealership is completely useless on just about anything.
