Sorry for the late reply, have been really busy. So Lexus opened the engine and inspected it, I also requested to see the engine myself. Cylinders looked very clean so no short block replacement was necessary. The only parts that were changed out were the piston rings, which they quoted as being "re-engineered". Sounds like a recall should have been issued if you ask me. Multiple other GS 300's were in there with the same issue. I plan on calling Lexus again to complain and ask for a longer power train warranty. This is something they should have addressed before they sold me the vehicle. Ill update this post with any updates.

Armitron, what was the outcome? I just noticed mine doing the same thing yesterday, oddly the same day I posted on this website about how flawless this car has been. I called my Lexus dealer and I am to keep an oil consumption diary. They mentioned there was a "whiff" in the air about Lexus coming good on this, whether or not my car would qualify if ever there was a resolution remains unknown.
I don't know how long I have been consuming oil, I change it every 8000km and have never checked it between changes. Didn't know I had to with a Lexus and every other car I have ever owned - including some notoriously unreliable North American brands - has not burned a drop of oil.
The car was born with and used 5-30 mineral oil, I switched it to synthetic two years ago. The dealer wants me to return to mineral, as this might have exacerbated my issue. Anyway, as I get more information and time goes by with my diary, I'll repost here, but I wanted to see what was done for you.

This is a problem all 2006 GS models have. The lexus dealership had to replace my piston rings. Luckily for me I had extended warranty and it was all covered. This is a very expensive fix out of pocket. What ticks me off is that this should have been a recall since the piston rings, according to lexus, were re-engineered. The original rings allow for oil to flow past the piston and then offcourse ignite, which in turn leads to oil consumption and some residue by your tailpipe on the rear bumper. I tried to argue with lexus about this to extend my warranty since they had to disassemble my entire engine, will never be the same as a new engine. After my fix, I noticed more power (normal) but my gas mileage dropped about 4-5 mpg which I am not happy with. I average about 26mpg now, use to be around 30.
Let me know how your whole thing pans out, but for sure that is your problem as well. I logged my entire fix with pictures, I suggest you do the same. Once they open your engine request to inspect everything before reassembly. Make sure your cylinders are not damaged. I also use fully synthetic oil and will continue to do so.

Good advice, thanks. There are are lot of people over on Club Lexus with the same issue, quite a few of them (most it seems) are getting the repair done at minimal cost ($500 for one person) or for free, well outside the warranty.
I will pursue Lexus armed with this information and hopefully they are just as nice to me. Funny, I was thinking of updating to the new GS, it is a work of art. I guess I'll wait and see how I'm treated. I was also thinking of the Chevy Volt - FWIW, I test drove one yesterday.
Anyway, I find it very hard to justify the cost of the repair, this is an obviously poorly engineered component of the engine. I might just fix it with a jug of oil kept in the trunk.

How many miles did you have on engine when this problem occured; is there a lexus bulletin for this potentail piston ring failure?

I had about 70k miles on the vehicle. There is not a bulletin for this issue, not one that I am aware of at least. From my understanding its an issue that has plagued many GS300's and in my opinion should be a recall but Lexus is staying hush hush about it. I was fortunate to still have warranty cover the repair but others are saying they negotiated the repair and got it done for a couple hundred bucks. If you see your tailpipe charred or darkening, then your rings are probably the cause. After my GS was fixed, I noticed a a increase in power and a drastic decrease in gas mileage. Use to average about 29mpg, now its like 23-24mpg.
Let me know if you have any other questions. Good luck!

My oil consumption remains at one quart in 5K miles. Last week I received from Lexus a CSP Customer Support Program notice. It has todo with engine misfire (Intermittently Runs Rough). The warranty has been extended to 2015 (9 years with no mileage limitations) for rings and may include the pistons. The program is limited to specific vehicles.

My wife's car had the problem fixed at about 94k as I recall. Now at 105k with no issues so far but didn't have any when the original engine had 10k on it.

Had the same problem, my GS 300 engine was eating oil, received a recall notice in the mail and took the car in two days later. They replaced the pistons and what ever else was necessary. The engine never actually leaked anything before the repair. Now it is leaking what appears to be transmission fluid and I am totally frustrated! Anyone have any ideas?

Hopefully you received the recal notice. It's the pistons and they have issued a recall.
