Per the 2009 Sierra manual, p. 5-16, "Do not add too much oil. If the engine
has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged."

In the high pressure to turn work at a pace that is way faster than anyone should have to be expected to perform atmosphere of a dealership service department some accuracy issues you are inevitable. The tech simply poured in the entire last bottle of oil instead of stopping with about 1/3rd of it left over. The "dealership" as an entity isn't out to try and sneak something by you as you suggested. This may well be the only thing the tech didn't do perfect while he/she got paid for about 70% of the time that actually gets invested to do the repair.
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.
Respectfully,
headgame01
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 purchased my 2007 used Yukon XL in late May 2011 with approximately 52,000 miles on it. I have had a 1997 Suburban (got to over 190,000 miles on it and then it was totaled after the engine started on fire) and a 2001 Yukon XL. I still have the 01 and it has over 160K miles. I never needed to put oil in these vehicles in between oil changes. I now need to carry a case of oil with me at all times. I had the car just over a month and saw the Low Oil message. I checked the oil and it didn't register any oil. I filled and then saw these concerns online. I then checked my oil at every fill up of gas. I have to replace one to two quarts every few thousand miles. It is always dirty brown except just after an oil change. I have gotten regular oil changes since then (every 3000-4000 miles). I now have over 88,000 miles on the car. I love this car except for this problem. I have addressed this concern with the dealership at almost all of my other repair visits. They have told me they are not aware of any issues with these engines. I would just like to know what GM recommends for action on my part to make sure I do whatever is needed to make sure this vehicle lasts at least another 100k miles. I am a dedicated Yukon XL owner and would like to continue to be but I am now wary of buying another one, especially if GM maintains their position that nothing is wrong with EVERYONE'S 07 Yukon XL engines.........
I would also suggest visiting another dealership if you are unsatisfied with the service. If you need any further assistance with this issue please email me at socialmedia@gm.com ATTN Amber. We'd be happy to help you as best we can.
Sincerely,
Amber N.

I don't know what the laws are for fraud there in your state, but if you don't want to waste your time, don't consult another dealership. Consult a law firm! How did Toyota and Honda pass GM by in volume? I think that compassion and honor have a lot to do with it. GM, You should be ashamed of yourselves!
Obviously this is a problem - you can read about it in various places on the internet. They have 6 readings which all were low after 1000 miles (they tried telling me it's normal to burn a qt every 1000 miles - i laughed - my 2002 Denali never burned an ounce). I think what they are trying to do is make it an inconvenient as possible so that I just forget about it. I'm going to forget about it all right - I'm going to sell it and never look back on GM. Their quality is suspect, their service is lousy, and they dont stand behind their products. I'm sure they could care less about "losing a customer" but I wont buy GM again and I definitely will steer people away if ever asked.
Hey everybody! Like all of you, our 2007 Gmc yukon burned 2 quarts between oil changes. The truck had 140,000 miles when it just started burning oil... I've looked around on Google and have found out that the main cause of the oil consumption was the active fuel management. There are aftermarket parts that can make it so it will disable the active fuel management. After this was done it doesn't burn any oil.
I am having my 2010 yukonxl with 93k miles in for the piston and ring replacement. Went through a few oil consumptions and there was a problem. Will check back once I get this done.
Are there any engines that do not use oil? The dealership was business like but showed some attention to me . Do you think this will fix the problem or am I better off dumping it and buying a F150 King Ranch
Hi vayukon,
Please keep us posted on your dealership visit. We're sorry that you've had to return for service, but we hope that your dealer is able to resolve this matter for you. If you have any additional questions or inquiries during this time, please do not hesitate to send us a message.

I just finished my last consumption test on my 2008 yukon which has about 83,645 miles, its seems that I will need to have my car engine taken apart and possibly have my pistons replaced. The gmc repair shop has just stated that since vehicle is no longer under warranty and its been 425 days since warranty expired, gmc will only cover 45% of repair cost and I will need to come up with 55% of the remaining cost. This yukon has burnt oil and I really do not feel that this is fair to me the owner for a "defect" according to me. This seems to be a very common problem with Gmc yukon apart from other issues with the locks and windows on my car. I feel cheated that this vehicle is not fully covered as stated 100,000 miles . I dont have 55% percent to cough up.
We have a 2007 Yukon Denali XL and are also experiencing a host of issues, along with high oil consumption. Our issue is that our local dealership keeps wanting to charge us a diagnostic fee for each issue, which would be nearly $800. In addition to the high oil consumption we have a host of electrical problems and transmission problems.
When we purchased the vehicle it was in the dealership 13 times in the first few months for problems. Our dealership told us they'd find us another vehicle (we purchased Certified GM Used) and they never followed through. We had nearly 100 calls to them for updates and they told us our vehicle was "too rare" and he had his guy searching 13 states. We have a white Yukon Denali XL. We see about 4 per day where we live. Not so "rare". We're so disappointed. We purchased this vehicle to tow our travel trailer and take trips with our family. Unfortunately, we haven't been able to tow for nearly 2 years due to all the issues that the dealership can't seem to fix. They just want to "guess" at the repairs and hope it works, meanwhile charging us astronomical amounts of money. So bummed.
I too have this oil consumption issue with my 2009 Yukon SLT with 52,000 miles. I first discovered the issue in the upper 30K mile range when it suddenly lost considerable power. I later discovered that the oil was being consumed by the engine after the dashboard light came on. The dealership service center required that I go through the oil consumption test whereby they determined it was consuming about 3/4 quart per thousand miles. They then agreed to replace the oil deflector per the service bulletin, stating that it should resolve the issue. Now, at 52K miles the vehicle appears to be consuming much more oil, approximately 1 quart per 1200 miles by my estimation. Aside from that, it appears that the dashboard light no longer illuminates to warn of low oil level/pressure. I returned to the dealer today with 4 months left on my warranty, and of course they want to go through the oil consumption test again. GM is obviously aware of this issue with the AFM engine and they are aware that the only complete solution is to replace the engine. I feel that at best they will only replace the rings, lifters and pistons which is only a temporary fix that addresses the negative affects of the problem, not the problem itself. I am dumbfounded by their claim that 1 quart of oil consumption per 2000 miles is normal. Would GM make this claim if oil was leaking onto the ground instead of internally? If this is "normal" then what is the point of having the oil changed as it will continually be topped off with fresh oil? If this is "normal" then GM should be required to disclose this information up front and list the "oil economy" figure along with the fuel economy figure.
Given the number of cases I have found simply by looking through various forums online, I am surprised that there is not yet a class action lawsuit filed against GM for this issue. [non-permissible content removed].
Thank you

Well, it all came to a head last week when the Yukon started smoking on startup last week and we took it in to the dealership yet again. This time it was definitely time for serious action. Pistons, Rings, Valve cover, Oil Deflectors, Lifters, etc. $4,100.
"But I'm sorry you are out of warranty by 20 days." "GM will help however and cover all but $1,000 of the repairs."
No, I'm sorry. That is not fair. If I would have brought it in three weeks earlier everything would have been covered. This is a pattern failure folks. GM has been aware of this for years. Their own TSB has been revised 5 or 6 times already (now TSB# 10-06-01-008G). They knew of the issues with my vehicle and documented it over the years.
We have always owned GM vehicles. 2 Chevy Blazers, 2 Tahoes, 3 Suburbans, 1 Yukon denali and this Yukon XL, etc. We have been happy with them in the past but their refusal to pay this entire repair is unacceptable and really makes you think twice about ever going GM again.
You have a six year old car with 76,000 miles and you can get a total engine overhaul for 1000.00??
I must be missing something here.
My question is if the GMC dealers know this is a problem why hasn't there been anything done about it?
