makes sense.
But like you said-- the ring on the wheels can also give the reduced power.. if its cruded up with stuff.

"Tiggergirl921" -- The question is -- did you, or your service center clean the throttle body on a regular basis (i.e. every oil change)? If not, and you just started cleaning the TB at 85K miles when the trouble started, then the TB is probably the culprit. There is way too much gum and gunk that slipped between the TB shaft and it most likely compromised the unit. I agree, it's a awful system design that GM produced, but at this point, I'd take the chance and buy a new TB and start with a fresh slate.

Thanks for the reply. That's where I'm leaning at the moment too. This was the first time I cleaned the TB, as I wasn't even aware of the issue until it reared its ugly head this winter. It was pretty nasty too. I just wasn't sure if the gunk built-up there could have really affected the sensor or if the problem may have pushed its way further down the line into the engine, etc. Getting the wheels off and the car lifted to really clean the wheel sensors can't really happen for me until spring when all this snow melts around these parts, so the new TB is probably my only option at the moment anyway. I hope it does the trick!

I just wanted to post up an update on the TB. Ordered a new one, installed it, and cleaned everything really well again. No more problems with the Traction Control, Stabilitrak, or Engine Power Reduction, so that is fantastic, especially as it's been -14 before the wind chill the last two weeks or so since I changed it. I'm still experiencing some idle/drive RPM issues though. I did the relearn procedure, and it seemed to have worked fine, but the RPMs still get a little jumpy at idle at times and the RPMs seem too much and too long when I'm accelerating at time. It's not a huge issue at this point, but I'm keeping an eye on it. Anyone else have these issues after swapping out the TB? Thanks again for all the insights on this forum about the TB issues. I can't even imagine what I would have had to deal with if I took it into the dealer.

Yes, the dealer probably would have sold you a new timing chain or intake manifold. My experience with the issues mentioned above, when the temps aren't so cold, I had the service stabilitrack, service traction control, stabilitrack disabled, the Mass air flow sensor is defective. The oil and moisture get in the snorkel and cause it to go bad. When I get those trio of messages I replace the sensor and problems go away. This winter the Reduced engine power has come up. I let the truck sit for 5 or 10 minutes and it thaws out enough to continue on my journey. The throttle had ice on it.
One trip I had to pull over and the water poured out of the snorkel upon opening it. I replaced the sensor and no more faults, I witnessed the ice formed on the throttle. I searched for a heater to put on the throttle to prevent this, but came up empty. I replaced about 3 sensors in the past few months. I get the cartridge from Rockauto for $50.
I did the PVC modification and now I get way less oil and moisture in there, but I had the throttle freeze up once since then in 1 degree temps. My last fault was just stabilitrack and not traction control with a MASS air flow code, the snorkel was not sitting right on the throttle so I believe air was getting in bypassing the sensor. This week no faults. Waiting on a new throttle body, snorkel, MAF sensor. I am considering installing a catch can, but cannot decide on which one to buy.
BTW what is the relearn procedure?

Like many of you, I am at my wits end. I was so excited when I bought my 2009 Chevy traverse in December of 2008. It was the first new car I had ever purchased, and it was a Christmas gift for my wife as we were expecting our second child. I thought that by buying a brand new vehicle that I was ensuring my growing family's safety for years to come. Now after owning the vehicle for only about 6.5 years, and after buying a second Chevy vehicle in 2011, I am left wondering what I have done to deserve this nightmare of an experience. If you look up problems with the 2009 Chevy traverse, I have probably experienced every single problem you would find. From water pump, to steering gear, to ignition coils, to transmission, to fuses melting, to catalytic converter, my wife and I (if we pay to have the vehicle fixed again) will have nearly paid enough to have bought 2 of these vehicles in the 6.5 years we've owned it. Sure, some things have been recalled, but a lot of the repairs were not under warranty and the problems were scary as **** for my wife who transports our 3 children in the vehicle daily. The power steering has gone out while my wife was driving it, the vehicle powered down twice while on the road with the kids in tow. This forum isn't big enough for me to list all of the things that have gone wrong, and each time I've had to shell out $2,500 here and $1,000 there, money that was supposed to be used to finally get ahead a little bit for me and my family. Each time we've reached out to our dealership to see if they will stand by there product, we get the run around and nobody from the dealership has ever even had the decency to explain why they refuse to do the right thing. I have a meeting with my dealership's customer relations manager tomorrow, and I'm not sure if I'll be able to contain my emotions, as this vehicle has destroyed my faith in GM, whom I will never buy from again. Now I'm stuck having to pay more than the vehicle is worth to get it fixed just so I can drive it somewhere to trade it in. No one in their right mind will buy it because of its history and, honestly, I would never sell it to someone for fear it would injure or (God forbid) kill them. If I see another GM customer experience rep reply to these posts with "I'm sorry you are having problems blah blah blah," I might scream (and I am about as laid back as anyone you'd ever meet). I have contacted GM's corporate office twice since my dealership was essentially just refusing to help me, and both times the corporate rep made it seem like they were going to help, only for me to find out that all they do is ask the dealership the same thing I could have myself. In other words....I just waited longer both times to hear I was screwed. When I was turned down the first time for assistance, I asked my dealership if there was a # I could call or someone I could talk to at the corporate office to plead my case and all they said was no!!!!!! I was happy when my tax dollars helped bail out GM as I believe in second chances, especially for American companies; however, my experience has made me wish that GM would have just gone belly up. I've watched my parents own cars for 10-12 years and not have a fourth of the problems I've had, and the countless trips to the dealership have really put a strain on me and my family financially. Now, with no legal recourse, and a company that is intent on not being accountable for its products or good to its customers, I am left helpless and having to find a way to pay for a car for my wife. I was told by the most recent corporate rep that it is up to the dealership to do the right thing if they choose to.....a corporate company that has no accountability....how convenient for them. Hopefully, someone out there will read this post and it will stop them from making the same mistake I did. At least then my pains will have helped someone. I am fighting the urge to say something rude to GM in this post, but I've learned it is pointless because there is nobody at GM with the authority to do anything other than what my dealership has done....which is basically not admit that they sold me a vehicle, the first one I ever bought new, that was a piece of junk and a danger to my family. It has really helped me to be less naive, as I used to think most companies had integrity and believed in doing good by their customers. How is there no law to protect people from this, I do not understand. Tomorrow....the rep at my dealership will finally have to face me and though it won't matter, he will know what this has done to me and my family. I have used every extra $$$ I have made asking them to finally "fix" my traverse and make it safe.... Only to end up here again...usually a month or so after it is "fixed." I paid the vehicle off a couple of months ago and now I am the proud owner of nothing and have to take on a note again. Thank you GM/Chevrolet, you have shown me why people hate big corporation's so much....and I am embarrassed for ever defending you and for thinking your product was "the most durable/dependable" product out there. If I had the money I'd sue you but I can't because I am not protected by the law and there is something deeply disturbing to me about that fact.

 

[Coach_B23]

One more thing. When a customer service rep offers to assist you, do not be fooled. You can accomplish the same thing they will by asking your dealership for assistance. The two times I reached out to GM, all the customer experience reps did was ask the dealer to look into offering me assistance which was something I had already done. Just prolonged the process of hearing no....which I had to call the dealership because nobody bothered calling me to let me know. Apparently there is no one at GM/Chevy with any authority to help you unless the dealership says they want to help...and why would they want to help. Forgive me if I'm jaded but I feel like I should warn others not to think GM is going to do anything special by contacting your dealership. Just ask your customer service technician at the dealership to see if you qualify for assistance and you will have accomplished the same thing that the GM reps from this forum or any other will. My question is this.... If I'm being denied assistance, with the gigantic list of repairs I've had to make, then that must mean there are people out there that need it more??? I'm not sure how that's possible. I could list the problems I've had with that vehicle but I literally had to put it on a spreadsheet to organize it all.

 

[Coach_B23]

And yes after having transmission replaced a couple of months ago, I had hesitation and had the replace 2 more ignition coils (the dealership diagnosed the 2 that were bad and I replaced the two that were bad). Worked for a week... Now the catalytic converter is bad. At least that's what they say caused it to power down on both my wife and I with our three kids in the car. It actually left me and the kids stranded one night. So it is in the shop now and they are saying the catalytic converter caused: the engine to power down, the stabili-track warnings, the power steering to lock up, and the brakes to seize up. I was barely able to turn into a parking lot in time to avoid an accident and wait for a tow truck. I am not o e of those people that rants at every little thing, but I don't know what else to do other than to vent publicly because there doesn't seem to be anything I can do except make more money to somehow get rid of this vehicle. If any one out there knows of any legal actions I might be able to pursue....please....please let me know. But I haven't been able to find anything yet.

Possible lemon

This is inresponce to Coach B23, Is it possible your 2009 Traverse is a lemon. I mean all the people I know that own a Traverse have not had all theses problems you have had. own a 2010 Traverse LTZ and it has been a dream. I plan on getting a new one in a couple of years. I like the way they have softened the dash. I really love this crossover. I would seek legal help. I really think you have a lemon. Let us know what happens. Best of luck to you :cheers:

 

[Coach_B23]

Jewel,

Thank you for your words of encouragement. The term Lemon only refers to a vehicle within one year of its purchase in my state. If a majority of traverse owners are not having problems then why does GM refuse to do anything to help me? I mean it seems logical that if all these people are doing just fine....then my situation would be out of the norm and would be worth GM looking into. Does that make sense? Sorry, I'm still a bit worked up over these issues. It just doesn't make sense if it is such a dependable vehicle....and I got a bad one....then wouldn't they want to help?

 

[Jewel]

I have heard that GM is slow in taking care of issues at hand. Have you gone to the top? I mean I don't know much about these problems. But I hope you get it taken care of real soon.

 

[bobg1951chevy]

Coach B23,

Your comments and ongoing negative experiences would have been more effective, would have attracted more readers, if you had started a new thread, instead of your comments getting buried within a stabilitrac thread. Your words and experiences are so important ..... maximum exposure is needed.

In my years with Chevy (retired now), I have NEVER seen or expected a dealership to "step up to the plate" to solve your issues, on their own, without the assistance and financial backing of Chevrolet Motor Division. Chevrolet Motor Division pays the warranty bills, not the dealership. Chevrolet Motor Division authorizes "buy backs", "warranty coverages", not the dealership.

I cannot imagine a "meeting" with a dealership individual, if I understand you correctly, to be helpful, in making you whole again.

No one should have gone through, what you have experienced.

 

[Coach_B23]

Bob,

Thank you for your advise. I have tried going to the top several times but all I can seem to get is senior customer care reps and they just contact my dealer. I've asked for a phone number or contact info to try to speak with someone who can help and I get, "we don't have any contact info for someone higher up?!" This is part of my frustration. The meeting at my dealership today is just to let the dealership know how I feel to give them one last chance to do anything to help me. I will update after the meeting so others who are following will know how it went. I will also start a new thread as you advised so others can see what I've experienced. I just updated my records and my car has been in the shop at least once each year we've owned it. I've done the work that I can to save $$, but other than that it was all done by our dealership. More info soon.

Yes, keep us posted. Chevrolet needs to assist, in this case ..... and in many other cases that get kicked to the curb. :banghead:

It makes perfect sense to GM. If EVERYONE were having the problem, GM would see it as a problem. If you're the only one, then it's a "fluke." Flukes happen; you fix it and go on. No special treatments.

Received the CODE P2176. Also received the Service Stabilitrac/Service Traction Control/ Engine power reduced. Cleaning the throttle body and resetting the computer by disconnecting the battery did the trick. No errors/issues going on 4 weeks.

Thanks
Mike

Newbie Chiming in.

2013 with 32K miles.
Service traction control/stabilitrac/engine power reduced

codes:
P228c low fuel pressure
P0171 fuel trim system lean
P0174 System lean bank 2
P228c Fuel pressure regulator low pressure (x2)

This happened over the weekend, against my better judgement I'm going to try to drop it off to the dealership Monday morning.

Pretty disappointed to see this issue span all Chevy products over 7 years and nothing at all has been done.
Sad to see it has to come down to multiple deaths and lawsuits until they admit there is a problem and do something to correct it.

 

[pjntj]

Would not start at all this morning.
Called Dealership, they are sending a flatbed right over to pick it up.
Correction: 38,000 miles.
+1 for the GMPP that we paid $1580.00 for, looks like it will pay off. Zero deductible as well! :cheers:

the Stabilitrack/engine power reduced comes on for many things.
Many are engine performance related. Like in this case- fuel related.
Not sure why you would say nothing has been done...
its designed that way.....

I'm failing to see your logic. Of course it "comes on for many things", but in a short few hours of research it seems to be an extremely prevalent issue over a number of years and most every time I see the fix is to clean/replace the throttle body. Now I'm not a mechanic by trade, just a tinkerer, but I fail to see what the throttle body has to do with the traction control system. (!!!!???) Obviously the dirty TB is throwing bad codes and causing this, or so I've seen so far.....across many models. Improper crankcase ventilation? oil buildup in the TB? C'mon GM really? Again.....I'm not a mechanic or engineer but this seems like a basic fix that could have been done a LONG time ago to prevent this very prevalent issue........I'm not a hater just yet, holding out hope my dealership guys know their stuff. We'll see what they say. Told them I had the "dreaded service stabilitrac issue" and the guy didn't bat and eye, he just said ok, we'll come get it...
