Apologies in advance for the long post.
Here's the next phase in my story on the Stabilitrak experience:
The morning after my last post, I jumped the Suburban with no issues and the car seemed to run fine again. Then on Christmas Eve we were on our way home from a short trip (5 miles) when the engine started to make a clattering sound and the Stabilitrak warning message came on. We parked the car as soon as we got home and didn't drive it again until two days later when I drove it straight to my mechanic's shop (still making the same clattering sound).
I work with a local, independent mechanic and I trust him a lot. When I pulled up to his shop, he heard the engine and said "That's not a good sound." He recognized the sound of bad lifters...maybe because he had seen two Suburbans (2007 and 2008 models) the same week with the same problem. Come to find out, Chevy has redesigned the lifters on my engine model 4 times since I bought my Suburban and they've also redesigned a portion of the oil intake from the oilpan. The issues associated with those two fixes will generally manifest themselves in excessive oil consumption (sound familiar anyone?) and rough running engines due to cylinders "dying".
Unfortunately, my mechanic confirmed pretty quickly that I had standing oil in places I shouldn't (so I needed the redesigned oil intake baffle) and I had a bad cylinder (so I likely needed the redesigned lifters). He was pretty certain it was "just" a bad lifter, but said he wouldn't know exactly what was wrong until he got into the engine.
After getting a $3,500 estimate for fixing both problems (included replacing all the lifters and some other maintenance-related stuff you wouldn't ordinarily do unless you're tearing your engine apart anyway), we investigated with a dealer and found that we were getting a pretty good deal. We told our mechanic to go ahead and do the work. He called me yesterday, after getting everything pulled apart and confirmed that the lifter on one cylinder was completely collapsed and was the root cause of the engine noise. He is also fairly certain it's been bad for a while and is the root cause of our Stabilitrak warnings. We should have the car back tomorrow and I'll get a full report from the mechanic on anything else he noticed. Hopefully this will be the end of our Stabilitrak woes!
When I originally asked him about the Stabilitrak warning messages my mechanic told me those were just the way the computer manifested any number of issues and that any competent dealership could read the diagnostic codes from your car's black box, do a little investigation, and quickly determine the root cause(s) of the Stabilitrak engine warnings and related engine behavior.
My advice to anyone experiencing Stabilitrak issues is to be an active consumer...read the forums and do your research to best determine what might be wrong with your car. Then find a mechanic (either independent or at a dealer) with whom you are comfortable and have them read the diagnostic codes from your engine. If you're going to a dealer, you will have to get past the receptionist and the order takers before you can talk to someone who works in the shop and will be able to talk to you intelligently about your car and it's issues. Be persistent. If you can't talk to the person reading the codes and doing the work on your car, go somewhere else. Everyone should have a mechanic they trust; if you don't, it's time to get one and this provides you an opportunity to do so. Invest some time in finding the right mechanic and it will pay off in $ and in the satisfaction of knowing someone competent is maintaining what is likely one of your biggest investments...your car.

No oil burning issues thus far . Your dealer tho , sounds like he is full of beans . No good engine should be burning oil like that . Seen an independent mechanic ? They are much cheaper .
#100 of 191 UPDATE-->Re: Any New Updates on this Issue? [mishelin]
Jan 10, 2013 (1:22 pm)
So the throttle body was replaced costing about $400 (after the "discount"). It has not given me any problems since October--KNOCK ON WOOD.
After reading the many posts here, I had some similar issues with other systems: (1) my tire pressure light is constantly on and won't measure the pressure in the front left wheel (2) The a/c was only working sporadically on long trips - would blow warm air after about 1 hour of driving (3) back right window works on and off right around this time. All of these items are things that have been reported by other tahoe/yukon owners before stabilitrak system went out.
My new question to the group is (1) has anyone gotten anything out of communicating their concerns with GM Customer Service (i.e. "Sarah")?? I've heard NOTHING. (2) Has anyone taken any legal action against GM related to the stabilitrak system failures??
It seems to me that GM is being negligent by failing to launch a recall on whatever is causing the stabilitrak system to fail. My concern is that something bad may happen soon and am disgusted that nothing has been done by the manufacturer to prevent. It may take all of us banding together (similar to Toyota Prius acceleration problem) to take legal action before someone takes notice and does something.
Thanks and be safe out there...m

Does GM, i.e Sarah, have anything to say other than "Have you contacted a GM dealer?" Seems as though plenty of folks have done that but without any great results or even good results. I have this problem, and had my two grandbabies in my 2007 Tahoe when it happened. Diagnostics can't find anything wrong! What are you going to do about it GM?????

Well ? Sarah GM , are you there ? Do you have an answer about why GM is not ordering a recall ? Do we just have to dump these vehicles & buy Fords or Korean , ETC. ????? Come on Sarah , give us some answers !!!

From a Customer Service standpoint, the main thing we're able to do is to collaborate with the dealership to see what the diagnosis is, follow up to see if a solution was found, and try to ensure your satisfaction with the experience. Additionally, I have documented this thread for further review by my supervisors.
I wish I personally could do more for everybody on this thread, but as I'm not technically trained and as I have limited resources to work with, I'm afraid that this is the extent of my abilities.

I have over 43,000 miles on my Tahoe that I purchased on June 1, 2011. It is my business car that is used for showing properties. Miles add up fast in Texas. I have another car that I use for my personal business. So if the warranty is only good for 36,000 miles, the Tahoe is no longer is protected.
#105 of 191 Traction Control and Stabilitrak issue
Jan 18, 2013 (1:45 pm)
Stabilitrak and Traction Control service messages when driving my 2011 Tahoe had been sporadic until now. Since the beginning of 2013 the warning indicator would come on about two times per week and go off just as randomly as it would appear. There was nothing predictable or constant about it. Luckily NEVER has the engine slowed or shifted to a lower gear like I read about in other posts. In fact, performance is not in any way impacted that I can tell. However, this week the same service indicator light started coming on and staying on. For now my Tahoe is garage parked until I can get it in to the dealership next week. Thank goodness I have another vehicle to drive.

FYI , I understand that when that "Service stability '' or such , light is on , the stability system & the ABS brakes are turned off . Through most discussions I've seen on Edmonds , it seems that most people are unaware of this . Good luck with repairs .
