I'm having the exact same problems with my 2007 Yukon XL. I've been working with the dealership in my town, and they have installed a deflection plate as per the GM bulletin. 3 weeks after that "correction" and 1800 miles into the oil change, I brought it back in due to low oil message. It was looked at and determined that it was down 1.5 quarts. Now they are saying they have to clean carbon from the pistons and rings. While the dealership seems to be working with me and doing a good job, I am displeased with the situation. How can I open a case with GM to get you folks involved to help me here. I'm concerned of the long term problems that could be caused by this issue. Is the only true fix to this problem replacing this design flawed engine? Thank you in advance for your consideration. Jeff-

I know GM customer service will probably email me from this post. It is not necessary as we DID receive our engine finally. My reason for posting is to tell the others on here, who are suffering as we did from the same angst, confusion and frustration, to NOT give up. If they do NOT have the same relationship I did with my dealership, to go elsewhere until you do. What you are experiencing with your vehicle is not normal. It caused mine to blow pistons/rods, to have lifters replaced TWICE and much more before they then put in the new engine block. Good luck to you all!
I hope that with your new engine that this vehicle performs well for you for many miles!

Bad news:
GM still doesn't care about this issue or their loyal customers, consider yourself lucky. This issue has been going on for at least 4 years and as far as they are concerned, there is no problem, its normal. I've owned 4 Suburban's in the last 12 years and won't be buying another. I have 143K miles on my current 2007 LT and pretty much need a new one.
I saw that you posted a previously opened case earlier, and I looked into that to see what had become of it. It looks as though your agent was unable to contact you and so closed the case. Would you like for us to set up a new case for you?

GM needs to fix these issues asap! I am really thinking about going forgein next time I buy (I cant believe I just typed that but its true!)
:lemon:
It starts out with being told your oil is low when you take it in for an oil change. If you change your oil regularly and drive under normal conditions, this should not happen. Don't let anyone tell you it's normal to be low. The next clue was white smoke on a cold start. This doesn't happen right after the oil change but maybe 500 to 1000 miles in. Again, I'm told that every car burns oil. Because of the smoke, I persisted and the dealer (who, by the way has a great service department) added oil and began a consumption test. After not quite 1000 miles, the car smoked again on a cold start and once again, I took it back to the dealer. At first the dealer said that GM requires 3 consumption tests before they proceed with any work on this but when they checked the oil and found it was 2-3 quarts down after 1000 miles, they said they could override that requirement. Following a GM service bulletin, they installed a redesigned valve rocker arm cover and asked me to come back after 100 miles for a recheck.
Well...after just 600 miles, the car began to smoke upon starting and my service engine light came on(this light had never come on before). I took the car in again and it was down 1 quart. This time they added the oil deflector and cleaned carbon from the cylinder. I went to pick up the car and when I started it, the service engine light came on, AGAIN! Needless to say, I left the car there again. Not sure what today's problem is! I have seen that some people have the deflector installed first and then the valve rocker arm cover. I'm not sure why mine was done on the reverse order.
Based on everything I have seen on this forum, I'm pretty sure the deflector will not fix my problem - isn't a deflector just a band-aid for an inherent problem anyway? I guess the next step is a re-built engine. So very inconvenient and frustrating!!
If this had been my only problem with this car, it would still be frustrating but I could probably deal with it. However, I've had several other issues as well.
Bad shocks when the car was new. This took a very long time and several dealers before it was actually diagnosed and repaired.
At 32k miles, service engine light came on. The throttle body assembly was replaced.
Next, around 75k miles, I had the reduced engine power issue that many others have reported. And yes, my car shut off a few times while driving - VERY dangerous!! After getting the runaround from my old dealer, I got this problem fixed with my current dealer. They replaced the throttle position cover.
I also had to have a door lock actuator/latch repaired because the drivers door wouldn't lock. This was a non-warranty repair so it cost almost $300.
These are the major things but I also have a squeaky steering wheel and the battery has died a couple of times, once after having the radio on for 5 minutes and once after having the hatch open for 5 minutes. The battery tests fine though.
I have to say that I really wish I didn't have these problems because I like my car. It's my second Yukon XL. My first one (2001) is being driven by one of my kids and has over 200k miles on it with no problems - ever! I took for granted that this would be the case with the 2008. One of the reasons you buy a new car is so you don't have to deal with problems.

My Question: If it is acceptable then why is the LOW OIL LIGHT ON?
My Answer: ***CRICKETS***
If the oil consumption rate causes fouling of a spark plug (or plugs) and results in a misfire then a repair is indicated. If not then you simply need to check and add oil as required, change it on schedule and enjoy your car.
For those who have engines that apear to not use oil, I have explained that as well and it has to do with the oils ability to hold certain contaminents in suspension and the amount of time that you routinely spend taking the car on long duration trips.
All the best,
Sarah

Emission Select Component Ltd Wty until 01/12/2015 or 80,019 MI
Your powertrain warranty went out in January of this year.
What is your plan of action from here? We're definitely available to assist in whatever way we can.

I finally took it back to the originally dealer i purchased it from. They agreed there was an issue and quickly replaced the Pistons/Rings. It's fairly recent but i could tell it helped w/performance and it doesn't seem to be burning at the rate it was (2-3 Q's in between changes). I'm hoping it's fixed but given so many issues, i still worry the engine should have been replaced. I didn't buy a $55k vehicle to piece mill key engine components which will end up limiting the overall life i could expect from this vehicle.
Many calls to GM, didn't seem to help. Guess i just got lucky that the dealer finally decided to just fix it. It seems like GM has very stringent constraints on their ability to do these things, replacing engines given it's such a wide spread issue w/the different size pistons that have been going in their engines. Apparently they changed how they handle this to help enable more volume builds but exposed to some variations which could turn into an engine burning lot's of oil, piston slap, etc.
Thanks but after the shenanigans at the dealer and all the problems everyone is having with their engines in about every GM forum I decided to trade in the "normal" Yukon. When I asked the service manager about the overservicing of my vehicle he told me that I checked the oil wrong. He states, "You cannot check the oil when it has sat for an hour....due to the oil passages being so small....at this point I shut down. He suggested I run the truck to operatinb temp and then wait 15 minutes. Wouldn't you know it was the same level! Go figure. I then asked him what overservicing a vehicle could do to the engine. He states "No problem. These engines can operate with one qt of oil extra just fine without any problems." He even stated, "They are built to tight tolerances?" Really?? I almost thought I was talking to a janitor.
I guess that is why there is a big bold statement to the effect of "operating an engine with too much or too little oil can cause damage......" in the Operators Manual. The more I think about it they probably put thicker oil in there as well to skew the test even more.
It is because of the dealership and the numerous problems across the web concerning oil consumption problems that I traded my Yukon XL in for a 2012 Ford Expedition EL.
I guess I gave my "normal" oil consumption vehicle to someone else. I feel GM knows there is a problem and they are trying to band aid fix these vehicles; coupled with my local service department trying to "play me" it was time to say bye to the GM brand for good. To make matters worse I now have learned that there are a few others that have had the overservice trick done to them at the beginning of this "oil consumption" test. If anyone gets one thing out of this...CHECK YOUR OIL LEVEL BEFORE YOU LEAVE AND MARK IT (a small scratch works well) AND LET THE SERVICE MANAGER KNOW AND WITNESS IT. MIGHT EVEN WANT TO START NEW AT ANOTHER SERVICE DEPARTMENT.
From a once loyal 30 year hardcore GM owner....now a new Ford owner.

BTW. As far as the door actuators as posted previously by another member: I replaced three separate door lock actuators and the last one was out when I traded the vehicle in. Also, the side body molding warps rather easily and starts to curl up and eventually starts debonding and cannot be fixed. It is a buy new, paint and replace item.
LASTLY. If anyone lives in the Fort Worth area avoid the GMC Service Department in Grapevine, TX.
Sarah, how can I get this really fixed?
I find it funny that GM actually told me that they could not be certain that if the engine was replaced that it would stop the oil usage issue. So funny. I guess they have no confidence in their engine department to make a good engine that does not use oil. Seems a little strange. GM is just waiting this out to get all these vehicle over 100 miles or 5 years which is this year (2012) then they will not have to worry about it.
I figure with all the extra oil I had to use and my time that I wasted coming in to the dealership, I spent about $5-7 K of my own money and lost time because of this issue. I wonder if a class action suit would get the engines replaced and quit wasting the GM customers time. But then the government owns them so what does it matter.

I'm sorry to hear about the drawn-out repair process you have been through; I'm sure that that wasn't convenient and got frustrating for you. It looks as though after all of the work that has gone in to your Yukon that the oil consumption concern you had had was resolved? How is everything running?
Best,
Sarah

I've since advised all of my colleagues and extended family to avoide GM products. We've always been only a GM family. We've purchased 3 brand new our selves and our relative have purchased many more. Venture, Aveo, Uplander, Cobalt, Saturn just in the past few years! That's over and GM can do as McCain once suggested, "Blame yourself!"
They are calling me every other day to keep me up to date, but it should not be dragged this long. What should I do next? Anyone have any good advise?
$3,000 would go a long way toward getting a crate engine installed.
