Filed Dec 9, 2018 · Driver assistance, Engine · 201,000 miles · TN

Stability traction control light keeps coming on while in motion. With major oil consumption problems. Just in regular driving I've had transmission, and rear differential work done fixed the problem for a few months now back again with flashing check engine light. Saying cylinder 6 misfiring. I've already sunk in over 4k in this after buying it last year in dec.of 2017. After reading comments this really should be a recall. With so many of the same concerns and complaints that have been listed.

Excessive oil consumption. 1 month of driving is equal to 2-3 quarts of oil replacement.

The truck uses a quart of oil every 1000-1500 miles. This is not good for the enviornment or my wallet.

Like to place a formal complaint regarding the oil consumption for 2007 chevy suburban and the horrible quality of vehicle. A few months after purchasing the vehicle the transmission gave out. I've been having problems with oil consumption and its horrible. I believe that chevy should stand behind their product and do a massive recalls for these vehicle. Again, chevy should stand behind their product. There are so many reviews about this same problem. Obvious there is a problem. Will never buy a chevy again nor will I recommend chevy vehicles!!

The door handles have cut three members of my family because the metal is peeling off of the plastic. Seat belts are falling apart and at least 3 of them do not latch at all. This is very dangerous. There definitely should be a recall especially for the seat belts. Air bag light is constantly on and the dealer of course wants to "fix" it and states that if there is a crash that it may not work properly.........this after I had the top half of the engine rebuilt due to oil consumption problem. Then there is the tire pressure monitor which apparently has issues after having new tires put on my car. Nothing but problems with this hunk of junk. Will never buy another chevy vehicle.

Excessive oil consumption - at least 1qt per 1k miles sometimes more. Chevy eventually fixed this under warranty after proving out the consumption. Chevy corporate is aware of this problem in these trucks and has not only written it up, but has designed a fix for it, dealer states chevy corp declined to issue a recall because it's a $1600 repair. The issue is two-fold. Something to do with the valves not sealing correctly and oil in the oil plan splashing up onto the cylinder walls faster than the rings can remove it. When my vehicle was repaired, they did some work to the valve train, replaced fouled spark plugs and added some type of baffle to the oil pan. Fix improved power, fuel consumption and reduced oil consumptions to normal levels. Truck now runs like new. If you are experiencing this go to chevy and demand the fix. You'll need to prove the oil consumption either through oil change logs, or as I did - which was to do an oil change at the dealer, have the oil plugs sealed by the dealer, then drive it 6,000 miles - having the dealer refill the oil when low to track consumption. They won't want to fix this because it's so expensive but demand the repair under the warranty.

Vehicle has excessive oil consumption, using more than 1 quart of oil every 2k miles. I purchased the vehicle at a gm dealership with 67k miles on it. They told me it was just serviced, and the dipstick showed to be at the full line with clean oil. About 4k miles later the low engine oil light came on. The engine oil life indicator said it had 49% life left. I checked the oil level and found it was more than 2 quarts low. I have researched this and found that gm is either unable or unwilling to repair. I will contact the selling dealer for the record.

I am seeing an excessive oil consumption issue with my 2007 chevy suburban. From my measure it is consuming 4 1/2 qts of oil per 3000 miles. The dealer acknowledged that this is a "known" issue but didn't perform any repairs. I am instead performing an oil consumption test. That's fine but I now have a family vehicle that I cant trust for anticipation of engine failure/lock up or worse engine burn up or fire from a low oil condition.

We have a 2007 chevy suburban it starting using excess oil around 21,000 miles when have had 2 oil consumption test done at the dealer. They replaced value seals 1,4,7,6 ..then started another oil consumption test. Low and behold it lost a quart at 1750 miles. They are now looking at replacing lifters...we currently have 33,000 miles on the vehicle..have to keep running back every 500 miles to get this check. At first they kept saying normal to lose a quart of oil but now realize it is not normal..have yet resolved the issue. Very upsetting to have a new vehicle and paid $48k and have to keep returning to the repair shop. We have looked up on the internet and it seems there has been many issue with this vehicle..
