GMC Yukon XL Normal Oil Usage?

179111213

Comments

  • So I am unfortunately an oil consumtion expert. I have had my 2007 since it was new. At about 30k miles the oil light started coming on every 2k miles. The dealership said it was normal. After a few times I complained. They did a consumption test, and I was down 1 quart, and said that 1 quart low in 1k miles was NORMAL. I lived with that answer for quite a while. Theyn I finally called GM. Guess what, it wasnt normal!!! I was excited to finally get a case number from GM and get an "Oil Deflector" put in (at 47K miles). Had a regular oil change at 51k miles, didn't even make it to 53k miles, and the light came back on. Now I am down 2 quarts. There is a new new bulletin from GM #PIP4492Z to update my valve cover now. Then they are going to replace all my pistons and rings. How about you replace my engine, being as that I have a WARRANTY and have been complaining for 25,000 miles!!!! Total CRAZINESS!
  • Good morning,

    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?

    Regards,

    same here, I had the deflector installed and after 1800 miles the light is back on again! THIS IS BANANAS!

    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!)

  • I've been reading this thread for a while and thought it might be helpful to share my chain of events with my 2008 Yukon XL SLT. We bought this car new. It now has 77K miles.
    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.

    On the phone with GM now, truck is at the dealers and once again they are telling me that the truck can burn up 1 quart per 2k miles is acceptable! WTF! This is crazy!

    My Question: If it is acceptable then why is the LOW OIL LIGHT ON?

    My Answer: ***CRICKETS***

    Everybody that reads thru this posting needs to remember just how all the "victims" were treated (and how one of their likely largest vehicle investments EVER was supported by the Company that built it...let alone with ObamaBucks). I've had Suburbans since 1972...MANY of them (gas, deisel, 2wd, 4 wd, etc. -- still have 2 <1999 and an 2007) and I will NEVER have another one!

    Engines use oil, I have written about that several times in this thread. Every penny wasted on trying to change the consumption rate of your engine would have been better spent by just handing you oil to add to it when required.The worst thing anyone could ever do is try and fix your engine as that only serves to enhance the perception that something is actually wrong with it.

    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.
  • I've been going back and for w/the dealers on all the oil consumption test for well over 1-2 years now. Noticed Yukon burning oil around the 45/50k mile, 1 Q per Oil change, had the valve covers, splash guard misc things done. Problemed continued. Dealer states just need to continue doing the consumption test, we have your back, don't worry! now that we have done this many times, going by the dealer every 1k miles, etc. Provided within a shadow of doudt that it's burning oil, we are handed a GM response stating this is normal and go pound sand. It started burning so much that the light began to come on, then after testing its burning atleast 1Q per 1k miles! finally took it to the original dealer, they seemed intrested in helping, now have replaced the pistons (state anyways, not sure given they only had it in the shop for 1 day, awfully quick but hope they did the work)... my big concern now is, if it truly has an engine problem, pistons slack, burning lot's of oil, probably a good chance that it has caused other wear and damage that will show itself fairly soon? thoughts anyone?

  • Hi, i picked it up yesterday. Like i noted, after dealing w/this for over a year now and approx. 50k+ miles, my original dealer acknowledged it was a real problem and replaced the Pistons/Rings. Very happy they finally did something of more substance, which is great. Picked it up, was told all the right things and it appears to run ok now. Will need to keep checking the Oil Consumption but i'm still concerned about the engine overall and given my experience, it will be very difficult to continue buying GM products. I have spent more money for years sticking w/American made and mainly GM, i've gone through several Suburbans, also have a 2500HD Duramax, typically pay cash for all of them. If i could look back, just short of 60k for this Danali and probably should have went w/the Toyota or Lexus equivilant but trying to be a good loyal american consumer. Dealer was great w/this last service, just being honest that i'm not sure i can continue doing business w/GM, nor recommending them based off this experience.

  • I am having the same issues with my Yukon xl my last 8 vin numbers are7r279057. Can u let me know if there are warranty or recalls available. I am using 2quarts per 1000 miles
  • OK, so after a deflection plate has been installed (as per GM Bulletin) and 2 sessions of piston and ring baths to clean carbon out, still the same old issue. My 2007 Yukon XL (after 800 miles since the last several hour visit to the dealer) The low oil light is coming on. Now I'm going BACK in today for oil change and the 4th oil consumption test. This is getting really old. If this was happening to my Mercedes, they would have fixed it, rather than playing runaround games and band aid solutions. Sarah, I would like to officially open a case directly with you/GM. Please let me know what you need to do that.

    flustered1,

    I checked your VIN and did not see any open recalls at this time. The following warranties are still in effect on your Yukon until the date/mileage indicated (whichever comes first):
    Corrosion Limited Warranty until 01/12/2013 or 100,019 MI
    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.

    Best,
    Sarah

  • Completed. Thank you Sarah.
  • So, long story short. I received a low oil pressure, stop engine now message. Low and behold I have no oil on my dipstick. I put about 3.5 to 4.0 qts of oil in. I made an appt with a local GMC service department in Grapevine, TX. He proceeds to tell me that this is normal, these vehicles are designed to burn oil. Furthermore, one qt of oil per 3000 miles is normal; thereafter 1 Qt of oil every 1,000 miles. So I would burn through 5 qts in 7000 miles, with the manuf recommendation being 7,500. It is up to me to check my oil and add oil as needed between oil changes. What the heck do I need an oil change for then. Regardless. So, I begin the dreaded oil consumption test. I leave the vehicle and pick it up later in the day after a fresh oil change, and surprising enough it took all day and the service dept is now closed and coordinate with new car sales to have my paperwork and key. The very first thing I did before I start my truck, is check the oil where they parked it (on level ground). It is overserviced by at least 1/2 to 3/4" over the top hash mark. Talk about trying to skew the results of an oil consumption test. Do you think I am taking my Yukon back there? Of course not. I will be making some phone calls next week. But I had to share to see if anyone else had checked their oil when picking it up from the dealer at the beginning of the "oil consumption test." Oh I had my daughter take pics of the dipstick with my Iphone showing the over servicing.

  • I spend months (50k+ miles) going through this same exact scenario. Pick it up after oil change, prior to starting another round of oil consumption test, it has an extra Q, which i guess helps ensure you don't run out but doesn't enable the results to be accurate (when nobody told they were adding even more than normal). After all the time, energy, effort and frustration of doing these test, i'm told it's normal, just go on about your business. Not to cool.
    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.
