GM has a resolute refusal to fix known, ongoing problems.
Our 2006 had the loose axle nuts, so did the 2009.
Our 2006 had a defective transparent top, so did the 2009.
Many of the problems that people report here today, were first reported on the 2005's. And we're not talking "one in a million" stuff. A few items get production fixes, but many of them do not.
GM is still wondering why our grocery-getters are Japanese.

Well, this is a follow-up to my post on page 1 of this thread. When I got the car up on a lift to install the Z51 front/rear sway bars with polyurethane bushings and Z06 front/rear shocks, I went straight to the oil pan. The left side of the pan was clean, 
. I looked on the right side of the pan and there's a drip of new Mobil 1 oil on the right rear corner of the oil pan. 
We identified the source of the leak was the plug in the passenger side of the oil pan that signals low oil level. I left the oil stain alone. When we finished the sways/bushings/shocks work and lowered it I went home and called the dealership service writer about the leak. Took it in today and...........talk about rather being lucky than good, the mechanic came out to discuss his findings with the service writer as I came up to the service writer to tell him I was headed home, Wifey was here. The mechanic says "This is gonna be a long repair. Looks like the rear main seal is leaking, gotta schedule the heavy lift to remove the front suspension and tranny to change it." I said WHOA............Wait minute. Did you read what the service writer wrote on the work order? I think it's coming from the oil level sendor on the RH side of the oil pan. He says "No, I didn't notice that." He goes back to his service bay and lifts the Vette up again. I show him that the drop on the RR corner of the oil pan that he thinks is a rear main seal is coming from the sensor plug on the right side of the pan. He flashlights it and touches the flange under the plug with his finger and says, hey that's where it's leaking from. An hour later after getting a half turn on the sensor plug, and cleaning the area, he test drives it and NO LEAKY. What a run around, and boy am I glad I was there when the mechanic talked to the service writer.
After all the warranty work done by numerous Chevy dealerships for LS3 engine oil pan leaks since 2008, you would think a upper level manager would assign a few engineers to analyze this issue and come up with a fix. How many hundreds of thousands of dollars has Chevy put out to the dealerships to repair the leaks. Fix it for crimeny sakes.

Wouldn't you think after all the years of building engines, GM would have figured out how to seal an oil pan properly so it doesn't develop a leak? The valve covers on my '85 Vette leaked on the exhaust manifolds and I was told this was a very common problem.
How come Asian engines hardly ever develop leaks? I've had numerous Hondas, Subarus, Toyotas, Nissans, one M-B and NEVER had an oil leak from any of them.
INEXCUSABLE!

What is it with these leaking oil pan gaskets!
This isn't the first time someone has reported leaking pan gaskets even on new LS3 engines.
Well, at least my 2011 GS hasn't started leaking yet ... crossed fingers
Oh ya ... we also have the loose crank pulley (harmonic balancer) problem on these engines too.

Beginning to believe that if the leak isn't serious, just better to leave be rather than risk a worse outcome.

Was your GS equipped with the Wixom hand built dry sump LS3?
Personally I haven't heard of a oil leaker coming out of the Wixom Performance Build Center, i.e. LS3, LS7 and/or LS9.
My 2010 GS with the Wixom hand built LS3 is totally leak free...........
Please offer your responses.

My 2011 GS (A6) has the 'El-Cheapo' robot built engine ... and it don't leak
And the oil level is right at the full line on the dipstick at 5,000 miles when I changed it last.

GM has a resolute refusal to make production fixes that solve ongoing problems- oil leaks, loose axle nuts, squeaky targa tops, cracking/crazing transparent tops, etc.
Look how long it took them to upgrade the seats and Blose stereo. And the seat meterials may not be any better, just look different.

The tech believes it is the gasket and it is under going replacement. I'll be able to pick up the car tomorrow. The tech mentioned he has had to do this several times on Corvettes. He didn't specify models/engines but he did mention it has happened to newer lower mileage cars.
For reference, its an 06 Z06 with 18000 miles.
Here is a thread on the Z06 section discussing the oil pan gasket leak.
