2007 Chevrolet Suburban: excessive oil consumption

Filed Apr 15, 2019 · Engine · IL

Engine is malfunctioning and using excessive amounts of oil (1 quart every 1-2 weeks). The manufacturer built bad motors in 2007 and knowingly covered it up. The vehicles were still sold to consumers and rather than fixing the issue (engine would have to be rebuilt or replaced) the manufacturer is placing all responsibility and cost ($9,000 fix) on the consumer, even when reported before 100,000 miles. The manufacturer knowingly sold lemon vehicles and refuses to fix.

The odometer instrument cluster went out on my 2007 suburban and the radio is changing stations on its own. Also the metal trim on my door handles and heating/AC controls is peeling apart and cutting my hands. In addition, the engine burns oil and I have checked it out by three different dealers/mechanics and they cannot find any leaks. I have seen a lot of similar complaints and I believe chevy should repair these items at no cost to owners.

I bought this suburban used in 2010 with about 32,000 miles on the odometer. I am the 2nd owner. From the day I bought it, it has burned oil. The add oil light comes on half way through a oil change. It's my 3rd suburban. Neither of those two had ever burned oil. It was still under factory warranty, so I took it to courtesy chevrolet in phoenix. They put it on a oil watch. I had to bring the truck back in every thousand miles so they could check the burn rate. They always said it was normal per chevy burn rates. Really? Check the internet for 2007 chevrolet engine oil, high burn rates and you will see that mine is not the only engine that burns oil. It sounds like chevrolet knew there was a problem, and instead of fixing the problem with integrity, they changed their burn rates so they wouldn't have to. I have lost all faith in chevrolet. I will never buy another chevrolet product.

2007 chevy suburban with 5.3 afm engine. Driving down freeway and traction control, stabilink and engine light come on. Misfiring real bad. After getting it to shop they stated no compression in 2 cylinders. When told service manager he stated what problem was right away. Then confirmed it. Knew right away because it is common problem. Stated problem dropped lifters which damaged camshaft stemming from afm system. Would have to pay to tear down engine to be exact but will need a motor either way. This has been a common problem with the oil consumption problem with this motor. I had been experiencing oil consumption for a long time. I would burn a quart of oil driving 1000 miles on long trips. Every week I'm a 1/4-1/2 quart low. Chevy says this is normal and denies there is a problem but this is far from normal. This also stems from afm system. An 07 chevy suburban that has been maintained should last more than 170,000 miles and chevy should stand by their product of a known issue. There have been fixes by chevy but none seem to work. I never formally filed a complaint with chevy or did oil consumption test( but they wouldn't have it if there wasn't a problem. I have just followed issue online waiting for a fix. But , motor died first. Also vehicle has a cracked dash which has been a common problem with this vehicle which chevy has since reinforced the places it cracks indicating there was a flaw in design but chevy refuses to fix.

I find it interesting that there are so many comments about burning oil on the suburban. I bought this car new in 2007 with 0 miles. In 2011 when had my usual oil changed and noticed that within 1 month my indicator came on that the oil was low and to add oil. I went back to the location where I had it changed and complained that they didn't properly fill the oil. The argued that they did and I was wrong. They then put 2 quarts in and I went on my way. A month later, again, the same issue. I took the car to the chevrolet dealer where we purchased it and they said that the reason the car was burning oil was because I should use a different weight of oil during the hot texas summer months. Ever since this time my car burns oil no matter what type of oil I put in. No matter what time of year - hot or cold. I keep extra quarts in the back for emergencies. When I start the engine on most days, but not all days, a white puff of smoke comes from the exhaust. The dealer insists that there is nothing wrong. It's obvious based on other consumer comments that this is a manufacturer's defect. At about 100k the tire sensor went and now at 113k another tire sensor is gone as well as the driver side automatic door locks. Typically when I take my car to the dealer to be fixed it runs at least $1000. I was planning for this car to last at least another 50k miles. We'll see...

The oil was 1 1/2 quarts low after only 900 miles. They filled it up and again in oct, it was 1 quart low after only 700 miles. I had a terrible family tragedy in dec and was unable to get my consumption documented however, I did have an oil change. I am not sure what happened and why it was not documented but, I was told that the oil tag was "missing" and that they were starting a new tag. In feb I went again for an oil change. On april 15th my oiling came on stating my oil was low and needed an oil change. On april 16th I noticed my truck start to hesitate and chug after taking off from a stop light or stop sign. I though perhaps it was bad gas. I used the rest of the tank and filled up on april 18th. On april 19th I noticed it was still hesitating and getting worse, now it was not only after coming to a complete stop, it was random and more frequent. The morning of april 20th I called al serra and told them I was scared and felt like it was a danger to drive my 5 children around in fear that we would lose power on the highway or getting on the highway or in the middle of an intersection. The service rep stated they could not get my truck in until tuesday. I was not happy with that answer and visited a local mechanic. Upon my arrival I told my mechanic that my car was hesitating and losing power. The mechanic test drive the vehicle and came back to tell me the oil was bone dry. He stated that if I had driven much further, the engine would have seized. He wanted me to how the vehicle to al serra e no help and stranded with my 5 children. Now, this has been an ongoing problem since january of 2012. Of course, my factory warranty has now run out and it is 3 months past the warranty of the repairs that were made. However, the ongoing problem was documented prior, much prior, to the repair warranty running out. Oil consumption gm ignoring problem.

My vehicle uses 1 qt of oil every 2000 miles right now, it was every 4,000. So the problem seems to be getting worse. When I shared this with the service department at both chevrolet and chevrolet, their response was that my issue was still with in specifications. I didn't realize that oil consumption was acceptable. Gm, instead of fixing the problem appear to be ignoring it. I have an 06 chevy silverado that has never used a qt of oil.

I purchased my suburban with existing gm warranty. The vehicle had roughly 47,000 miles on it and 7 months remaining of the original factory warranty. After about 900 miles the low oil light came on, which I thought was odd because I checked the oil life gauge after purchase and it said it was at 99% oil life. This worried me. It was one quart low so I added it and decided to see what happens. A month later at about 1000 miles the same thing happened. I added another quart and then went to the dealer closest to my home to report the issue. They started monitoring. Each time at between 900 and 1400 the oil light came on and I was a quart low. They began remediation. First the pvc/valve cover remediation. This did not solve the problem. Then next the oil pan related remediation. This did not solve the issue either. Now I keep having to take the suburban to the dealer when the oil light comes on, they add a quart and say there is nothing they can do, from a legal stand point because I have an extended warranty and the car is out of gm warranty (remember I reported this while it was under gm warranty and reminded them of that), that gm won't do anything more from their experience with this issue. However, they have not contacted gm or opened a case file and wont do that. I was told I will need to pursue that on my own. They tried to reach out to my extended warranty but say they are put on hold for 10-15 minutes and have to hang up because they are too busy to wait longer. I've called them repeatedly asking that a case be opened with gm as this was reported under warranty and is a known defect with this engine (I'm out of warranty now) but they just keep giving me the run around. Gm needs to do a recall and address these engines.
