Engine Burning Oil problems of the 2008 Chevrolet Suburban

The vehicle has had numerous engine issues and abnormal oil consumption. The motor has failed at 149,000 miles and follows the pattern of numerous other complaints. Oil consumption lifter noise complete engine failure.

Apparently there was a technical bulletin issued for this truck. The special warranty was for 120,000 or year 2018. In 2015 I disputed the engine failure and also the oil consumption and the#7 cylinder. My truck was at 170,000 miles and gm refused to pay for the repair. On August 20, 2016, my truck was having the same problems. I returned it back to the same dealer and they said it was the same problem again, this repair was performed less than a year. I called gm again and they refused to make the dealership warranty the repair from last year. Gm knows that this engine is faulty and refuse to recall this 5. 3 engine. Now I have to pay for a new engine.

The contact owns a 2008 Chevrolet Suburban. While driving various speeds, the vehicle lost power and the vehicle failed to accelerate when the accelerator pedal was depressed. The contact stated that various warning indicators were illuminated. The vehicle was taken to manassas Chevrolet (8000 sudley rd, manassas, va 20109 (703) 596-3031) where it was diagnosed that the catalytic converter needed replacement. The contact stated that the catalytic converter was replaced, but the failure recurred. The vehicle was then taken to luck Chevrolet (516 s washington hwy, ashland, va 23005 (804) 368-6473) where it was diagnosed that the number one and seven spark plugs were covered with oil gunk. The spark plugs were replaced. The dealer also stated that the motor in the vehicle was burning oil and continuously caused the number one and 7 spark plugs to fail. The contact stated that the failure would recur every 3-4 months. The manufacturer was notified of the failure and did not assist. The failure mileage was 120,000.

The engine has a design flaw and consumes oil rapidly, loses oil and deteriorates internal parts of motor causing total engine replacement or repair. This motor is currently apart of a class action lawsuit but the lawsuit is only for this engine in the 2010-2013 vehicles. This motor however has been in gm vehicle since 2007 and I assume that the company withheld this information from consumers and public just as they did in 2010. I believe that gm should be responsible for the design flaw of motor in all vehicles that included the engine. Personally I had to replace my motor for excessive oil consumption at the cost of $7,712. 13 which included taxes. Then, of course, the motor you put in inherently has the same issue and its just a matter of time before it fails due to excessive oil consumption. The lawsuit is going to be filed for 2010-2013 models I think there should be a recall and I would like to see pressure to include earlier models with the exact same motor.

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 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.

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 “michele” 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.

Excessive oil consumption of the 5. 3l engine. It 'burns' a quart of oil between 1100 and1500 miles. The TSB issued on the engine fixed nothing. Chevy said they won't do any more which is indicative of the corporate culture at chevy. This has been an ongoing problem.
