Congratulations on your new grandson! I'm sorry that this exciting moment was tarnished with the reduced engine power situation with your vehicle. I see you're already scheduled to go into your dealer to get this looked into; please update us on how this goes!
Best,

GM IF YOU CARE ABOUT PEOPLE....ISSUE THE RECALL ALREADY!!! I'VE FOUND HUNDRED'S OF POSTS ABOUT THIS SINCE ENCOUNTERING PROBLEM THIS PAST WEEK.
I see you were thinking about visiting your dealer this morning - how did everything go?
Looking forward to any updates,
Sarah

The first problem is the mechanism itself. When one does a google search for the errors we are receiving, you will find that this is not an uncommon problem with Impalas and more often than not the throttle position sensor is at fault. This, in itself should prompt a recall since the saftey of the vehicle is compromised and can be compromised even the first time this indicator lights up. Also, take note that Impalas are not the only GM product affected by this very issue.
The second and probably the most baffling problem is the programming of the computer system (assuming it is in the programming) which disables the vehicle while it is in motion. If this is a command issued by the computer system then this would be a design and engineering flaw and should be taken seriously but it appears that it is not. Never should the computer system shut down or disable any critical system while the vehicle is in motion.
All that aside, why does Sarah (GM rep) seem very disconnected with the issue and the safety concerns of everyone here. We have purchased a product by the manufacturer she represents, but there seems to be an overwhelming lack of concern by her or GM (or both?) on this very issue. It seems as if they are saving face by their presence. I expect that companies should learn from their mistakes, but this design flaw has been appearing in GM vehicles for quite a while now and is not something they are unaware of (ie; just the presence of their rep in this forum is an indication that they are aware of the issue).
Sometimes the only way to get big companies off their butts to do anything about a problem is to bring that problem to the public attention through the media as well as lawsuits and complaints. However, sounds to me like GM is biting the hand that feeds it since they took our money to save themselves yet ignore saftey concerns where their customers are concerned. Shame on you GM
I understand that your Impala is experiencing the reduced engine power/service stabilitrak concerns intermittently, and that this can make it difficult to get diagnosed. Have you been in to one of our dealerships to have this looked at as of yet, or are you planning to do so?
We're here through Customer Service to support and assist you through the repair process as our first priority; our activities and interactions are documented into the data system we use for all interactions with our customers and dealerships (phone, internet, email, white mail, etc.). This data, particularly the data we can generate through service requests, is combined with data from our dealership service departments to help brand quality make decisions on our products.
I apologize if we have appeared to be disconnected with this concern you all are having on the forum; we're doing what we can but are also dependent upon hearing from the members of the Edmunds community so we can get service requests set up to work.
If we can assist you further, please contact us at socialmedia@gm.com with the following information: your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your involved dealership.
All the best,

Has GM filed a recall yet?
Maybe, if enough people say something, GM will be forced to fix this with parts made of metal and not plastic. Throttle Body
Such a safety issue. Instead of being scared of getting into an accident, I'm fearful I will be the one causing the pile up. GM come clean and issue a recall. Something needs to be done.
And I dont know if any one has lost the automatic start function when this issue occurs. Seems to go hand in hand with mine.
All the best,

In addition to the accelerator and its sensor, is the throttle position sensor in the throttle body also prone to malfunction? I am beginning to regret that I bought this car. I have a 1999 Mazda 626 V6 with a 5 speed a manual transmission which I bought new and now it has 334,000 miles and still runs great. Now I prefer driving the Mazda to this Impala.
I agree with many posters here that preponderance of cheaply made Chinese and Mexican parts have made these cars quite cheap and unreliable. I already had to replace the driver's side door panel on my Impala because the vinyl was separating from the material underneath. And guess what? The new panel is beginning to do the same thing. I am still under the basic warranty, but I am getting frustrated. The leather seats in this car are the cheapest imaginable and poorly stitched together somewhere in Mexico. The ones in my Mazda are still better looking, except for some wear in the driver seat from scuffing. The rear bumper on this Impala is huge and poorly supported on the body especially on the sides, so you can see it sagging in some areas, which looks awfully cheap. This is visible mostly on light color cars, like mine (white).
And don't get me even started on the alloy clear coated wheels. I already have some pitting on this car, with 12k miles on the clock, spending most of the time in my garage. My 2006 Silverado Pickup wheels are even worse and the truck has only 18k miles on it. GM evidently specs out these wheels with the cheapest quality clear coat imaginable so they stay looking good until the car is sold.
Most likely this is going to be my last GM car.
I realize that overall you are not satisfied with your Impala, and I'm sorry for that! If we can document your concerns with your vehicle, or look into anything, please don't hesitate to get in touch by emailing socialmedia@gm.com

I want to see what they say about it being covered on the warranty.
To GM Rep Sarah,
Yes I already had this vehicle looked at by the dealer and I am disgusted that it is not covered under the PowerTrain warranty, and I refuse to let them put in the same defective part that is already in the vehicle. And if they are replacing them with a different part, than maybe that's a sign they should recall them ALL! So again, I cannot wait to sue GM after this obviously prevalent problem causes me or my children harm, and then I will use the money to buy a Ford.
I am buying a remanufactured Throttle Body, and replacing it myself. I will let you all know how it goes.
I understand your frustration. I am thinking of trading and eating about 2,000.00 to do so. I will by a Ford next time. My contour I just got rid of had over 175K+ miles on it and the transmission quit, only in the shop 3 times in its life!
My problem was my traction control and stabliight control came on and told me to service it. Then as soon as that came on my reducing engine power came on and my car lost all power. Thank goodness I was not going fast. I was to the throttle body. My part listed on my invoice is J5584 Accelerator Peddle Position Sensor. It found DX code P2138, followed DOC ID 2614036, Replaced Throttle Body Pedal Assambly. this was on 02/28/2012 and so far so go since the replacement.
I hope this helps you.
I hope that your recent move went smoothly and that you're able to settle into your new home okay. I see that you're not feeling confident with your dealership options at the moment; if you would like for us to work with you on this repair, please contact us at socialmedia@gm.com (in order for us to update our database, we ask that you please include your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and your preferred dealership).
All the best,

Thank GOD this happened in the work parking lot instead of the 6 lanes of bumper-to-bumper traffic I drive through every day to get to/from work. I am very concerned that I could have been hurt while driving my car. I don't understand why this hasn't been addressed by GM given the number of people experiencing this dangerous problem.
My car only has about 42,000 miles and the bumper-to-bumper warranty expired only 5 1/2 months ago. We're still making payments on the car! My wife and I own two Impalas (She has a 2007) that we bought brand new. I like GM vehicles and was planning to replace our cars in the near future, but I swear I will never buy a GM vehicle again if GM will not take care of this problem.
My mechanic has reduced it down to a computer issue. I can only hope this will be the solution and not take any more money out of my pocket. This is such a shame.
Some notes: Definitely happens more on hot days. Happens at high speed and at idle. Seems like moderate speeds without stopping are the safest speeds without getting the error (25-50mph)
Took it to his mechanic, couldn't pinpoint the problem, but cleaned a couple of things and was running fine.
Today the lights came back on, so he managed to get it to a dealer - $350 later, they fixed the following: 122483 defective app sensor, scan test, check code P2138. Check terminal pin grip at x111 connector and at gas pedal connector, ok. Add grease to terminals. Replace accelerator pedal unit. Clear code and recheck, ok at this time.
I guess time will tell if this is the right fix. I really hope so, as I would hate for anything to happen to him or I while driving that car.
Can anyone here please confirm if this was the right fix for this problem? :confuse:
Thanks in advance!
I have only 44000 miles on this car...never buy chev again...
So I took it the dealer and got it fixed. The codes were P2122 and P2138, they replaced the APP (Accelerator Pedal Position) sensor. So $461.
2009 Impala, I got the traction control~reduced engine power~service throttle starting disabled, yesterday.
If I had gone one more mile without the car stalling, I would not have had cellular service. Called AAA and it took them 20 minutes to track down my exact location. I travel a lot of rural areas and would hate for this to happen when I was without phone service.
If GM doesn't want to issue a recall, maybe Impalas should come with lifetime Onstar service!
I previously had a 2004 Hyundai Sonota with 175,000 miles. Never once did I have an issue with that car. I wish I had kept it.
Additionally, it would be of WAY more value if the solution were just posted here, where everyone could see it without having to take the additional step of emailing or calling. If someone's got a solution, post it here! That's why we host the forums in the first place - to provide a venue for people to get help, right here.
