If you insist on being a victim then that's what you will be. Since when did eveyone get the idea that a car is anything other than a machine that requires service and repair on a consistent basis? It's true that much of the blame belongs with any manufacturers or their sales people who attempted to promote their product as not needing as much servicing as the vehicles in the past did. Then another healthy dose of the blame belongs to "consumer experts" who sell their opinions to those who will listen to them as they usually only tell the consumers what the consumers want to hear.
Machines (cars) break and need repaired. An engine that needs oil added at various intervals between services is NORMAL!Those two situations do not make you a victim, they make you a vehicle owner, the only question right now is whether you are a responsible one or not. If I played the consumer expert line and pretended that it isn't normal for an engine to use oil you would be happy to listen to me because it's what you want to hear. Telling you the truth, tactfully or otherwise will likely make this something people who want to make someone else responsible for their problem unhappy.
Now the symptoms you described SUGGEST that your having an issue with one of the wheel speed sensors or it's wiring. That could cause the traction control system to falsely think your experiencing wheel slippage and that could cause the system to reduce the engine power at times. Without feeling the "sputtering" your experiencing frst hand there is no way to know if this is a false traction control issue or if your engine is misfiring. Does your Check Engine light flash, or is it already on?
If this is a misfire and you have a flashing check engine light, you need that car serviced right now, not later. A misfire will in turn damage the catalytic convertor and then you would have an expensive repair on your hands and want to be the victim all over again when you had the ability, as well as the opportunity where you could have done something about it.

Not sure who you are addressing on the Oil Consumption issue, but I respectfully disagree that oil usage of the level that people are seeing is normal. To use over 1 quart every 1000 miles is not normal. As a matter of FACT if you read the manual and GM policy it is way over what is expected. Also, a FACT is that GM has issued a service bulletin about the oil usage in 2007 5.3 L engines. There are very defined steps that have to be taken to verify this but in most cases they end up basically rebuilding part or all of the engine by the time they are done. So, to sum the Oil issue up that most posts on here are addressing, you need to read them and get a clue as to what they are talking about. If it was not an issue the GM Customer relations would not be on here asking to help with the situation that many dealers refuse to acknowledge exists.
As for the Sputtering Engine piece. You are correct it could be many things and people need to either have the knowledge to evaluate it or take it to someone who does.

My 2007 Yukon XL was consuming more than a quart of oil every 2000 miles beginning around the 65,000 mark. After 40,000 of on going oil consumption monitoring by the dealer and 4 separate procedures on the engine to patch the problem, my engine was finally replaced by GM at 105,000 (about 750 hours). Patients and persistance won out for me this time.

It's difficult for this discussion to take place without letting emotions get in the way. By what criteria are you making the statement that an engine using oil isn't normal? The vehicles are equipped with a low oil level detection system, as well as the good old fashioned dip-stick. If engines truly never used oil why would they be necessary?
Having been a mechanic/technician since the mid 70's and having personally rebuilt hundreds of engines it's fair to say that I know a little more about them than the average person. I know when they need taken apart and repaired, and I also know when it's a waste of time and money and there has never been a greater waste of resources than I have seen take place when the reported problem is an oil consumption issue, and nothing else.
Let's play with a scenario. You have an engine using a quart of oil in 1000 miles. The oil costs $5.00 a quart. So in 100,000 miles you would spend $500 on oil that needed to be added. Attempting to repair that engine let's put the number at $2000, and lets say it's "successful" and now you only use one quart in 2500 miles. You'd still be spending $200 for replacement oil in the next 100,000 miles plus you have to figure the $2000 for the service work which means you spent $2200 to save $300. Now tell me how that is reasonable.
The only thing that is occurring here is many of the posters want this repair if and only if they can get someone else to pay for it. What you don't see as a "consumer" is you end up paying for all of this in the end because the manufacturer has to pass any costs of doing business right back onto their customers in one way or another. No matter how popular the solution may sound as in "they replaced myengine for free", it may have been free to you at the moment, but every other consumer actually had to chip in and pay for it.
As far as the routine to try and curb the engine oil use rate covered by the bulletins, I'll remind you that I am a professional mechanic and have access to every bulletin ever printed from every manufacturer. If you read the posts in nthei very forum you will find failure, after failure, after failure, to alleviate the concern when following those bulletins. This isn't the first, the only, nor will it be the last time any manufacturer deals with such reports. Trying to fix something that isn't broken results in no change in the vehicles operation. Replacing the engine can of course make a difference for a short time but typically the same neglect that set the stage for the first consumption issue is rarely corrected by an owners service habits and the new engine turns around and eventually suffers the same fate. Meanwhile someone who understands and accepts the situation rolls merrily along at a fraction of the cost of any of the repairs with a vehicle that serves them wonderfully as long as they care for it like they are supposed to.

I have a customer who has a 2002 Toyota Highlaner that has used about 1qt of oil per 1000 miles for the last four years. She got used to adding oil as required and now has just over 225,000 miles on the car and it's doing just fine. The last time she was in she asked if it will see 300,000 which means she will plan on replacing it in about four more years. There is no reason that I can see that suggests she won't get that far. But she will be adding oil the whole time,with no where near the expense nor the futile effort of trying to "fix" it.

Good luck getting it resolved!! I have been dealing with the same thing and much much more for over 40k miles now. 6 different oil consumption tests (using anywhere from 3-4.5 qts in 3k miles) all showing problems, "fixed it" multiple times just to have the same issue before the next oil change. Problem is dealers around here want you to drop your car off first thing in the morning and leave it all day for an oil change... when you have kids and a job thatís hard to do. Mine has been nothing but a headache.. problem after problem. I have replaced (all before 100k) motor mounts, throttle control position sensor, battery, sway bar links, ball joints, the power lift gate and power running boards went out, cruise control stopped working, transmission slips ALL THE TIME and I baby this vehicle!! I have always been a "GM" girl, every single vehicle I have owned has been GM same with my husband as well. I normally get bored with a car and change every couple of years but was hoping to have my Yukon to 300k+ like I did my 99 Silverado with the 5.3 (and never had to touch the engine)... BOY WAS I WRONG!! Not only is it junk, but everyone knows they are junk so good luck getting your money back out of it. We are in the market for a new car and my husband REFUSES to buy another GM vehicle and I am on board with him. After repeatedly dealing with GM's "supposed" customer service department and got absolutely nowhere (except to customer service reps that can barely speak English) I don't know what else to do. I leave messages all the time for different reps and never get calls back. Iím told now that the engine really needs to be replaced, it stinks horribly bad of burning oil all the time, exhaust smells like rotten eggs ( cat converter apparently needs to be replaced too) You would think after spending as much money as we do on these vehicles they could at least stand behind their products

looks like you had many of the same issues we have had w/or 2007 GMC Yukon XL Denali. We replaced just about everything, the oil we battled from around 40kmiles up to 100k miles. Finally the dealer replaced the piston rings, which seems to have stopped the burning. It still doesn't run like it did earl on, seems sluggish, transmission seem to jerk and slip at times, could never get anything done w/it. Now air-ride system and rear shocks seem to be out. Reported the motor that provides the air but was told that noise was normal...typically challenges you run into when trying to report problem. They want the car all day, then don't fix, you have to keep trying but they act like your crazy at times. Oh well, $55k+ vehicle and nothing but issues. I won't be buying another GM car...always tried to sticko American made cars..always GM but i guess none of them are worth it, nor truly American made in the end.

I completely agree, it is so frusterating!! Especially when you look at how much money we spend on that GM brand! Its sickening... I wanted to roll my window down and say sorry to someone I pulled up next to at a stoplight today that had just bought a brand new Acaia, but I bit my tongue and kept driving. Eventually consumers / customers will figure it out and be where we are, and GM will be belly up.

After 40,000 miles and ongoing fixes (4) as well as ongoing oil consumption test, GM finally replaced our engine!!
