Engine Burning Oil Problems of Chevrolet Avalanche

I have a 2008 chevy Avalanche ltz with the 5. 3l v8 engine with adaptive fuel managment. It was purchased used with 120k miles. It became apparent that the engine was consuming oil, 1-2 quarts per 3000 miles. Recently the engine started producing white/blue smoke on start up and oil consumption increased to 2-3 quarts in 1500 miles. My vehicle is currently at a mechanics shop and I am told that for starters I will need new valve covers that are redesigned from the original ones and that excessive oil consumption is common on this engine. I have read of other owners that have had to have pistons/rings, valve covers replaced, and a baffle placed into the oil pan to mitigate the oil consumption. This seems to be a fairly common occurrence that isn't a typical maintenance issues since these parts weren't oem when the vehicle was made. It seems unacceptable to have to have oem modifications completed out of my pocket for something that seems to be identified as an issue with specific parts made to mitigate the issue. I am very concerned what this acceptable oil consumption will mean for the longevity of my engine.

Vehicle has 120,000 miles on it and has a random misfire, with traction control and stabiltrack warnings and a flashing check engine light. Engine has excessive oil consumption and runs rough. Installed new plugs and wires, no change. After reading up on these engines I found out that the afm / dod feature is a common failure for these engines. Gm should step up and help owners with some of the repair costs. This is going to be expensive.

My 2012 Chevrolet Avalanche 5. 3l engine has started a oil consumption loss. There was a service bulletin issued oct. 30th 2013 to correct this problem. It does not fix the problem! what I've read is that where the cylinders deactivate to help fuel economy after time those pistons get damaged from not having fuel or fire on them and itdamages pistons and causes oil consumption. In the past few days I have found out that there are 5 people I know with the same issue. Looking on line there appears to be class action law suits all across the country on this issue. Gm/Chevrolet know they have a problem but refuse to take care of this problem. There is no recall on this and I'm sure never will be because it happens when the engines reach higher mileage. I have all my maintenance records on my truck and had no intention of trading it, but now the motor will have to be rebuilt or replace.

Stabilitrak and traction control lights keep coming on and check engine light. Loses power and stability while going uphill or accelerating. Gm service out of warranty. Looked at possible recalls none available. Noticed alot of issues regarding 5. 3 v8 from 2010 to 2013 gm models. Excessive oil consumption also. Do I just pay for a new engine or is anyone doing anything about this oversight by gm? thousands of complaints but no accountability.

The vehicle, from the time it was new, had usually consumed about 0. 5 quarts of oil each oil change, which I would consider normal. This condition began to worsen at approximately 60,000 miles to about 1. 0 quarts per oil change. This condition continued to worsen, and at approximately 85,000 miles began to consume 1 quart of oil each 1,500 miles in city driving, and closer to 1,000 miles with significant highway driving. I contacted the dealership regarding this issue, and they replied that this amount of oil consumption would be considered normal. Between 85,000 and 135,000 miles I have replaced spark plugs twice. In each instance the plugs were fouled and wet with oil. The ignition coils were replaced on multiple cylinders at the time of the first spark plug change. As compared to the owners manual, the spark plugs should only require service every 100,000 miles. I have since contacted the dealership regarding this issue, and they continue to reply that the amount of oil consumption I experience is normal. I have owned more than 10 vehicles over the course of +30 years and never had an engine consume oil at this rate. This amount of use is neither normal nor good for the environment.

Excessive oil consumption. It the 5. 3l with active fuel management system. Gm knowns there is a problem and the only fix is to replace the rings and pistons or replace the entire engine at the owners expense, 5,000. 00 - 8,000. 00. Since it's it's a design flaw, I feel they should fix it at no cost. It consumes over quart and a half per 1000 miles, both highway and city and at times 2 quarts with pulling heavy loads. I have done a oil consumption test with the dealer and they have admitted it goes through a lot of oil. I bought the truck used, and the dealer who sold it to me never mentioned this truck could have this problem.

At 40000 we noticed we were having issues with my Avalanche burning oil, when we asked the tech at chevy he told me that was normal for the newer engines to burn oil, at 130,000 mile we started having problem with a spark plug fouling out, I read that this was directly related to the oil consumption problem. At 181,000 mile and only four years old we had to replace the engine after replacing the spark plug and wire 3 times this cost us $6847. I have read this is a constant problem with the 5. 3 engines and could cause4 major accidents if the end up on a highway when they finally go out.

I bought this truck new and at about 30000 miles it starts to burn oil. About a quart between oil changes. Took to dealer and they replaced lifters. There was no difference. Then did oil consumption test where it got to the point of burning 1quart of oil every 800 miles. Took back in then was told extended warranty will not cover and it is normal wear. Truck at that time only had 73000 miles on it(Aug. 2015). They told me it could be$3600 to repair this issue. I than told them not to touch it and still dealing with issue at 78000 miles.

There have been continual problems with the engine of my truck and I have found out since buying it there are severe problems with a lot of the engines of the 2007 Avalanche. The mechanic told me when we brought the truck in to find out why the engine had a hesitation in it, that we should hope it was the exhaust system seals needing to be replaced that caused the hesitation because the only other times he had seen this problem it was a manufacturing defect in the 2007 GMC engines that he had seen these problems with alot of the 2007 chevy and GMC trucks including his own. We also about 2 months after buying the truck noticed that the truck was going through oil very quickly but the mechanic said that the seals weren't leaking so didn't know why we were burning oil so fast. The dash has cracked at the corner of the air bag and if there is an accident it could send shards flying. The drivers door sticks and the stability control go's in and out of working order. The electric mirrors stopped folding in and tilting down and tried to have it fixed but Chevrolet said they wouldn't give the mechanic the code to get into the computer system to fix it and the back up sensor that had stopped working also. We now have to go to a Chevrolet dealership to have it fixed. There have been so many problems with these trucks that Chevrolet hasn't fixed these trucks even used usually cost at least $15000 brand new you could double or triple that price I don't think it's a lot to ask to have a decent engine the other problems I could deal with but the engine problem they should fix.

This vehicle has had oil consumption problems since purchased. It runs out of oil 1500 miles after an oil change. Several consumer complaints have proved this is a very common problem and suggested reporting it to the epa. My truck now needs a new engine because of this common defect with the afm and bad lifters in the 2007 Chevrolet Avalanches. It is completely abnormal for an engine to burn this much oil into the environment. Not to mention the consumers who are now being forced to replace engines due to this problem. It needs to be fixed.

The contact owns a 2008 Chevrolet Avalanche 1500. While driving approximately 30 mph, the check engine warning light illuminated and the vehicle stalled. The vehicle was taken to the dealer multiple times over a span of three years where it was diagnosed that the throttle position sensor and the program sensor kit needed to replaced. The contact also stated that the LS valve cover, number one plug, cylinder head, piston rings, and a deflector needed to be replaced. The vehicle was repaired and an oil consumption test was performed over a six month period. In addition, the engine was flushed; however, the failure recurred. The manufacturer was notified of the failures. The failure mileage was 43,000.

At 73000 miles transmission broke just a few months out of warranty. Also started experiencing excessive oil consumption and noisy engine. Have heard and read too many reports of people with the 5. 3 liter having major mechanical problems I. E. Camshaft lifters piston rings and valves all going bad.

My main concern is the fact that the vehicle burns excessive amounts of oil. I have lodged about five complaints with ourisman rockmont Chevrolet and my concerns remained unadressed. They did, on one occasion, change a gasket cover and oil pan gasket, but the problem persisted. Finally, I was recently told that I needed an oil deflector per a service bulletin and was told it would cost nearly $1,500. 00. Although my concerns were all made during the warranty period, ourisman is attempting to charge me now that my vehicle is outside the warranty. I contacted chevy customer service but no luck.

1. Brakes-again. . Pushed on the brakes and pedal went to the floor 2. Noise still coming from suspension 3. Can smell oil burning returned vehicle to university motors they checked brakes and told me no correction was needed. . . . Suspension noise was told that was just how the vehicle sounded, I could feel the vibration on the floor. . . Oil smell--they tightened the oil filter.

Engine uses 1 qt per 2k miles of engine oil, according to dealer this is acceptable, but if not noticed or checked it could lead to engine failure. I would have not bought the truck if it said "engine burns oil".

Consumer noticed engine excessive oil consumption every 1000 miles one quart of oil. Dealer has inspected the vehicle and is under oil consumption test. Please provide further information. Ts.

I have been undergoing an oil consumption test on my 2002 3/4 4x4 chevy avalance for almost 6 months. The service bullitens the dealer gave me had to do with '95 or older cars or with the new car braken period. (I have over 30,000 miles on it) at first they told me the sevice dept forgot to reset the light, now they say this is normal usage,1 quart in 1000 miles. I am thinking of having a reg. Shop check the oil level as well as the dealer, because what I am reading is not what the service dept is writing on their report. One of the sevice techs told me in confidence that I am not the only one complaining about this problem but chevy isn't going to admit that there is a problem because of possible legal action. How long do I have to continue this testing before something is decided?.
