They are turning out to be a crooked organization; I thought they were fine up until this experience and I learned that stabilitrac is in fact a SCAM to get you to service your vehicle for an unnececary addition.
I suppose it replaces the old rotten corporate policies of making things that fall apart sooner so you have to replace them.
I'm having the same problem. They know it is viral; and effects all vehicles. Because they know of a dangerous condition, they open themselves up to some nice lawsuits when someone REALLY gets hurt.
I see that your engine shut down while you were on the freeway and I'm sorry for the risk this may have put you at. Have you already worked with your dealership or customer assistance?

But you've got the dirty job of customer appeasment for a blatantly corrupt corporate policies; it's like bank tellers explaing why a customers accout was charged $10 a month for stinkin' bankin', or why HP computers would break down after 6 months, etc., or microsoft updates that hinder options.
It's the old "consume the consumer via policy dictatorship".. It's corporate manipulated consumer cyclism; corruption at its worst.
Stabilitrak reminds of those globalist initiatives; the direction society is taking is to buid crap that wont last and create ways to FORCIBLY leech off of consumers.
All due respect, but I will probably do extensive research before my next vehicle purchase.
I will check in time and time again.
I wish you all luck with this and keep fighting the fight. GM has to acknowledge this is a wide spread issue and public safety concern.
Good Luck!
Most of the mechanical devices on the Tahoe/Yukon are connected to the central computer.
When the car's computer detects an engine problem or specific electrical problems, the computer is designed to reduce the engine power significantly to avoid serious damage to expensive engine or transmission components, and the generic message "Reduced Engine Power" is displayed in the vehicle's instrument cluster.
The message by itself does not indicate what exactly is broken. To learn more, you must download the diagnostic codes from the vehicle's computer found in the engine compartment. Your local mechanic or auto parts store can likely do this for you.
These codes can help further pinpoint the problem, but are still not enough to fully solve the problem. For example, the computer may identify the throttle body as the problem, but the computer will not be able to determine whether the throttle body needs to be cleaned, needs to be replaced, or whether the wiring between the throttle body and the computer is faulty.
In my particular case, a rodent has chewed through the throttle body wires connected to the computer as was evidenced by the various bite marks on the wiring. Because my Yukon is at 114k miles, the well-worn throttle body was replaced as a preventative measure, and the chewed wires were cut clean and spliced back together. It was not necessary to replace the wiring harness. Because the wiring job was somewhat labor-intensive, the total parts and labor charge from my mechanic was around $500.
I highly recommend finding a smart mechanic who you trust and sticking with him. My mechanic has a degree in electrical engineering, and whenever possible, he loves to repair instead of replace. While he couldn't save the throttle body, he did a terrific job splicing the existing wires, which saved me the parts and labor of a new harness.
Well it ran fine and I didnt have any issues, until about 2 weeks ago. I started my Yukon and it had a very hard time starting. For about five seconds, it sounded as though I was running out of gas, or like the the gas wasnt getting from the tank to the engine. Then after the 5 seconds, it just kicked on as it normally should. This has happened 3 times since I got it back from the dealer.
Then yesterday, the dreaded CHECK ENGINE light again. uuugggghhh... it stayed on for half the day and turned off. A few days ago, I received "tighten gas cap" warning.
I am almost convinced that it is a fuel issue....anyone have similar issues? or comments for that matter...
And for those who said, "yah its fine now, but just wait," you were right.... BARRRRRF....

I feel bad cuz the guys at the dealership were very nice and thorough. I totally thought the issue wud be fixed....But after hearing the way my vehicle started, i am thinking its a fuel issue....anyway, what do you need from me for the SR?
If you were to send an email to either of the addresses in my profile, we could get that set up. Please include your name/Edmunds username, phone and address, a brief description of the issue at hand, the last 8 digits of your VIN and approximate mileage, and the name of your dealership. My coworker Christina, who answers inbound emails from the forum, will advise you further.

Customer service was great as usual. I just don't understand how the replacement part is $44, and the labor was $150...I wish i had some mechanical skills so i cud save myself a little bit of money.... oh well.... i feel your pain guys, but i cant give up yet even if i wanted too...i still owe too much on mine...
Thank you for the update on your concerns. I understand your thoughts about the cost, but at lease there is a warranty on their parts and labor. Keep us updated on your situation.

I'm sorry to hear you're having these difficulties with your new '06, and can tell you're frustrated with the experience. If we can be of assistance in working with your dealership, please send us an email to socialmedia@gm.com (include your name/Edmunds username, phone and address, the last 8 digits of your VIN and current mileage, and the name of your dealership).
All the best,

There are two things it is now consistently doing. It runs rough (hesitation) when you first pull it out on to the road for the first couple miles until it warms up - then it seems to smooth out. If it doesn't smooth out or if it starts acting like it is going to go into "limp mode," I can engage the cruise control and it takes care of the problem. The cruise control does "jerk" the throttle on a long down hill run though. Does anyone on the forum have any ideas as to what the problem might be? Our dealership can't figure it out.
I bought it new. It had 5 miles on it when I drove it for the first time. It has been a great vehicle until this problem crept up. It still looks great, when it runs it still runs like new and drives as good as it did when it was new, but it has become totally undependable. It just makes me sick....
The only fix that I have found that works, for now, is adding Seafoam dewetting agent, find it at any auto parts store. This means that there is nothing wrong with the intake portion of the engine. There is something wrong on the exhaust portion. Ia m guessing an O2 sensor or fuel filter, just ordered them and hope to repost for an update on what happened.
I will not buy a GMC again. Not due to this problem, due to the lack of commitment from GMC to support the people that have bought their vehicles. I just want a safe car for my family to drive in.
Thanks!
If you wanted to get us your case number, we would like to look into this further. It would probably be most efficient if you wanted to email it over to socialmedia@gm.com (please include your Edmunds username, and perhaps even a link to the post so we make sure to include everything -- my coworker Christina answers inbound emails).
All the best,

So, coming home from a funeral 200 miles away I hit a little bump on the interstate, my door locks started clicking locked and unlocked, my instruments went crazy and I lost engine power. After I finally got it to the side of the road and turned it off, I set there of a few minutes and when I restarted it it ran fine. Ran fine for about a week then it left me stranded on the side of the road.
I have moved from a large metro area to a small rural area so we do not have a dealership here. (Don't think I would use a GM dealer anyways). My mechanic has driven the 200 miles to me and has been going over my vehicle for 2 days with a fine tooth comb. I will let you know how he resolves this if he is able to. I called GM and got an incident # on this. The last time I was given an incident # was also electrical, but because I was in an accident due to their proven faulty wiring they jumped through hoops to try and get things resolved.
Spread the word, DON'T BUY GM PRODUCTS. They not only don't care about the crap they sell, they could care less about you. They lied when I called them and stated that they didn't have any other incidents like mine in their records. And then I find this site with all the comments from GM Customer Service Agents. They should be ashamed.
I wrote a $50,000 check for my Yukon. They can kiss this GM customer goodbye as well as my 5 daughter and their husbands.
They aren't going to admit that their vehicle have any problems until there is a significant number of deaths involved. I don't want to be one of them. Just want to get this fixed so I can get rid of it.

Thank you for the post! Can you please elaborate more specifically on the problems your Tahoe had before you replaced the catalytic converter? I would love to get my Denali fixed.
Thank You!

I'm glad to hear you were able to get everything worked out - I'm sorry that you had to go through this experience, however. Is your vehicle still in the repair process, or do you have it back?
Best,

Today I replaced the TB cable myself with P/N PT2628 with 18" pigtails purchased from autopartstomorrow.com for $75.80 which included S/H. I tinned the wire ends, slipped shrink tubing over the pigtails, used a crimp on sleeve as a splice, soldered the wire connector after crimping the splice, then shrunk the tubing to insulate the connections. I used a heat resistant tubing to fit over the entire cable. Being an electrical engineer before retirement, I did it right. The wiring cable and connector were about 10X the quality of the GM factory cable and connector previosly installed by GMC about 2 years ago. But, much to my dismay, I drove the truck about 100' before a return of the REP.
Today, after the return of the dreaded REP, I cleaned my old TB that I kept after it was changed the first time. I did a very thorough cleaning of the TB and even removed, polished, and then aligned the butterfly valve. Then I noticed what could be the problem that has been dogging all of us. The male connector on the Throttle Body itself has two nickel plated pins (1 & 3 from top left) and eight gold pins. In engineering we used to have nothing but trouble with nickel plated pins and corrosion and afterwards always specified male and female connector pins of gold. It looks to me as though GM found a way to save 30 cents in cost instead of doing the right thing. The female pins on both the old and new cable connectors were gold. I cleaned all the contacts and will install the newly cleaned TB this weekend. I'm actually going to GMC in the next few weeks and look at a new TB and see if the contacts are now gold.
I've got to find a solution soon because my inspection runs out this month. No way it would pass inspection even if I could get it to run for more than 15 minutes without REP. Right now it is a real danger not only to me but to others.
I have also expressed my absolute disgust with GM's response to the many problems that I have had with my vehicle since it was purchased new.
My vehicle needed a new battery every year until the problem suddenly stopped. The dealership never acknowledged a problem or said what they did to correct the problem. They just kept putting in new batteries.
When I complained about EXCESSIVE Oil consumption the dealer told me that it was well within the "guidelines". Now that my vehicle is completely off warranty and still going through oil, the dealer is telling me that there is a bulletin out regarding an engine part that malfunctions and it would only cost a couple of thousand to fix the issue.
I hope that people are reading Edmunds before the ever buy a GM vehicle!
having this issues again not even a year later. Due to the number of complaints I see via e-mail and online, GMC should consider investigating the THROTTLE BODY before someone gets seriously hurt or killed.
If you can let me know where that clamp was i would be grateful.
I will report if any further problems occur....
