2007 Chevrolet Suburban excessive oil consumption

Sounds like plenty of of us have this problem to varying degree's, but nobody has a solution. Any lawyers out there want to start a class action suit ?

How much oil are you needing to add? Is there any evidence of a leak under the car. The car is awfully new to be consuming excessive amounts of oil between services. You are under warranty, so I would take it to the dealership to see if there are any problems that need to be fixed.

I have a also have a 2007 Suburban that has this issue. It started at 20,000 miles and has had 4 major repairs done and still consumes. I finally took GM to court under the Lemon Law. I have all the service bulletins that discuss this problem and an e-mail from GM that states after all these repairs have been made and it still consumes oil-don't fix it, GM is still reviewing the problem. If you have done any research online, you will see many cases like this.

Update- I just brought my 2007 Suburban for low oil problems. The dealer told me there is a new service Bulletin out from chevy. It states that is within chevys acceptability range to burn 1qt of oil per every 1000 miles... I think something's wrong here ....

I also have a 2007 Suburban, low oil light came on after the first 3000 miles. We added a quart, then took it into the dealer. The service manager told me that this was normal for the engine, and that they would have to monitor it every 500 miles to confirm. I am just glad that it's a leased vehicle, soon it will be someone else's problem. I had a 1999 Suburban for 8 years, 150000 miles, and never had to add oil. Same engine.

No its not normal. This is a fraud. Let me explain. A client of mine (I am an attorney) made a Lemon Law claim, GM ignored/denied her claim, and then we were supplied with an Internal PI (preliminary investigation) report that outlined the oil consumption problem stating the cause was unknown (although thought to be stuck piston rings) and that replacing the rings was no guarantee because, again, the cause is unknown. Meanwhile, GM pretends there is no problem (that it's within there oil comsumption guidlines which were created arbitrarily to combat these complaints), when not only do they know a problem exists. However, its simpler to deny that a valid claim/problem exist because they don't know what the cause is or how or if it can be fixed(thus, a recall would be pointless).

I am having the same issue with mine!

I have a 2007 Suburban which I purchased used. Did not take long for the oil light to come on. I use approx 1 quart every 600 miles. After sitting for 6 -8 hours, a great deal of blue smoke comes out of the tail pipe. Does not do it while driving. Have been working with my dealer tracking oil consumption. They finally agreed that something was wrong an asked me to leave it with them so their engine guy can do a diagnostic. The day i was going to take it in, i recieived a call and was told by the service guy that they had heard from GM regarding this issue and that they were providing a replacement part to be installed that would solve this problem. Strange that they know this will solve the problem when hey really do not know what the problem is....anyway....I am documenting and will not be satisfied until he problem is fixed.

I have a 2007 Suburban 5.3L. I purchased the truck with 33K miles and was surprised to have the oil low light come on before my first oil change. I changed oil and soon found that it needed 1 qt between changes (3K intervals). Now with 54K miles the engine oil low light comes on approximately every 1000 miles. I have consistently added 1 qt as soon as the light comes one and continue to change oil at 3K intervals. I've owned many vehicles over the years (including a 1966 Internationsl Scout with over 150K miles) and have NEVER had anything use this much oil. Very dissappointing.

I bought my 07 suburban new and have had oil leak/oil consumption issues from the start. 1st it was oil pan gasket. Then oil pan and rear cover were replaced due to defect during manufacturing. Then it was the front cover gahebsket leaking oil. Finally, the dealer said that GM has determined that the lifters are the cause for all of the issues. Supposedley, the lifters are pumping to much oil and GM is in the process of "re-engineering" the lifters for replacements. They originally told me parts would be ready Sept. 09. NOT! Then it was Dec. 09. NOT! Then it was March 2010. NOT! Now its Oct. 2010. We'll see. Regardless, I'm done with GM vehicles. This is second one in a row with serious issues. We had a 2005 GMC Yukon that had 3 steering gear boxes replaced in the first 36,000 miles. I buy new vehicles so I don't have to deal with issues like these. GM's response to the oil problem is pathetic.
