2008 Suburban 135K. Vehicle has been running well, all routine maintenance was done. Without any warning the vehicle was 3 quarts low on oil. Dealer checked engine told new engine needed. I was told a common problem further investigation I noted far to many similar complaints. This seems to be a defect in engine design. It should not require deaths before this issue is investigated. Like so many others repair cost is an unexpected burden. GM response the vehicle high mileage and age are a factor. This problem has affected vehicles with a rang of miles. GM should recall the 5.3L engine and repair the defect. The first issue with vehicle I was driving on highway the warning light came on. Please take the time to look into this issue. GM has indicated 2 quarts of oil being burned in 3000 miles is normal. Please take the time to look into the matter. GM shouldn't be the only bail out. No prior warning was given, no warning lights or low oil indication, no leaks.

This engine is burning 2-3 quarts of oil in between oil changes (car has less than 50,000 miles on it). This is the only car I have had in 30 years that burns this much oil. I am constantly adding new oil to this engine and still having to change the oil regularly in order to stay in compliance with the manufacturer's warranty despite refilling half of the oil with new oil between changes.

My 2008 Chevy Suburban with 94,000 miles stalled while in traffic traveling at about 20 mph without warning. I luckily was able to coast it to the side of the road and after letting it sit for a short time it did restart again but only to stall again after the car ran for another 5 minutes again traveling at about 20 mph. I had it towed to my dealership and have been told that my crankshaft position sensor has failed. While my VIN and year is not covered, there is an active recall on this condition (GM recall no. 06083.). this is a very dangerous issue to have especially when traveling with small children in the car. The recall should be extended to other years who experience this issue for the safety of families.

This vehicle has always used an excessive amount of oil. Must add at least one quart between each 3500 mile oil changes. No leaks have been detected and nothing seems to make a difference.

2008 Chevrolet Suburban. Consumer writes in regards to the disappointment in the manufacturer due to numerous vehicle repairs. The consumer stated the vehicle would run rough, the check engine light illuminated, the service stabilitrak and traction control lights illuminated when some of the cylinders shut down, the lifters were not properly lubricated, causing them to fail. The engine consumed large amounts of oil. There were noises coming from the oil pan and transmission area, 3 of the 4 door locks actuators were replaced, the rear liftgate broke for the 4th time, the right retractable mirror was inoperable, the cruise control worked about 505 of the time, which was probably tied the throttle positioning sensor going bad as well. Also, the vehicle had significant electrical problem, where certain lights would illuminate on the dashboard, there was an audible clicking noise, that sounded like a relay firing very quickly.

My 2008 Suburban started burning a tremendous amount of oil. Seems like I was continuously adding oil. Raised the issue with the dealer, who indicated it was a common problem but probably not worth the expense of fixing if I could keep checking the oil. This advice was also based on the fact that all my maintenance has been performed at this dealer, so they know the vehicle well. The last week in January was very busy and saw me driving about 100 miles a day. On Thursday, about 30 miles from home, the check engine and traction control lights starting blinking, the car lost power, and the engine began running rough. This was on a very busy highway (U.S. route 50 near annapolis) during rush hour. This created a dangerous situation. I was eventually able to get the car home. When I brought it to the dealer, they said the oil was dry (I had checked it the previous weekend), a lifter had broken, and a piston head was scored. The cost of work to fix would exceed the cost of a new engine. I now have a new engine, the cost of which was not in my budget. This experience reflects what has been have reported frequently on automobile related web sites.. given that this is a design flaw, Chevrolet should be covering at least part of this fix.

Last year 2012, the Suburban was blowing smoke out tailpipe, less than 100K miles, so dealership installed new valve cover with proper grommit for PCV under warranty. Sept. 2013 115K miles, engine bucking, dash lights all on, running on 7 cylinders, Chevy dealership states #1 spark plug "came out". and that oil pressure sensor was bad, but still pressure, so not urgent....Nov 19, 2013 - truck now making 'back fire' noises and pressure sensor moving back and forth across 40....afraid will break down again. Also, have peeling chrome on inside door handles like prior complaint, that is cutting hands/fingers!

I purchased a 2008 Chevy Suburban ltz on September 24, 2011. Shortly thereafter I began to notice that the oil pressure gauge seems to behave erratically, I later learned the car burned oil. I took the car to the dealership in January of 2013 complaining of oil stains on my driveway and that I had placed two quarts of oil in my car within one week. The dealership explained to me this was a common problem and that I would have to have about $4,000-$5,000 of repairs done to rebuild my engine. They also explained that this was a warranty item and that GM would cover it. I was informed by the dealership that GM told them that I had to go through an "oil consumption test" which I did, they performed an oil change on January 31, 2013. I brought the vehicle in for service on February 19, 2013 and the dealer notes that it has burned.75 (3/4) of a quart of oil. When I asked if GM would fix the problem, they said no, that another test was needed. I've never purchased or owned a car where burning oil is acceptable. I brief google search of "Suburban oil consumption issues" results in approximately 2.8 million results and there are several pages discussing this apparent common problem. I called GM on February 19, 2013 and was only able to speak with [xxx] and a supervisor in the philippines who assigned me a case number I believe this is a large problem and want a recall and fix.

2008 Chevrolet Suburban 5.3L afm oil consumption --> extremely frustrated with GM service given me the runaround regarding a poor engine design which leads to bad rings and high oil consumption. Bad rings can be verified by doing a compression check on the cylinder, as opposed to checking how much oil is being used per mileage. Excessive usage is define 0.5 quarts per 500 miles. Last three oil changes, I have use 6 quarts in 3000 miles. My vehicle is under warranty, and they are trying to delay the problem until it is out of warranty. There is numerous complaints of this online. They should replace the pistons and rings and afm lifters and add the new oil baffle.
