Did for me anyhow!
My car had the slap when I changed the oil at the first 500 miles? It stayed that way until the car got up to temps then went away. It was really bad when it was a cold morning. But I have happy news for me since I have done my cam swap with springs retainers and push rods the noise is completley gone????????????
It does not matter how cold it is it does not make a noise other than more valve train noise but not bad. But the slap is gone I am so happy.!!!!!!!!!!!!!!!!!!!

GM has deeeeppppp pockets, I wouldn't want to take them to court. Also I was reading another lawfirm's website and the deal was they keep 40% of any recovery and that was dealing with the piston slap issue.
My 2002 has it.. and it hasn't seemed to effect the power any 
Its at 24,000 miles
My 2001 WS6 "slaps" too and it has 37,000 miles, but neither of the cars use oil.. heck.. I'd be afraid to let a dealership work on them.

Out of curiosity, how loud is this, exactly? Keep in mind that I think my current exhaust setup isn't *quite* loud enough...
I mean, maybe this is a real issue, but maybe you're all a bunch of wimps who are afraid of what a REAL engine sounds like. I mean, this is an LS1... if you don't want to hear your engine, go buy a lexus...

some people will sue over any little thing. my TA has it but with the performance, gas mileage, and reliability it has shown so far, i couldnt care less what it sounds like on startup.
as for the guy that says its embarassing, your car could probably walk all over anyones who would make fun of you for it.

my o3 vette has is also but only when the motor is cold. that why i always allow pistons to expand and get up to operating temp!
definately more noticably this winter, temps as low as 20 degrees

Piston slap is inherent to a short-skirted piston design when cold. That lawsuit is a farce... Now if your noise doesn't go away after warm-up, you have issues that might be seriously affecting your engine.

I also have a case nasty piston slap. If it's so normal why would GM replace pistons,blocks and extend warrantys????? WHY??? Am I sue happy? NO. Do people deserve to be told the truth and have it fixed on something they paid 25,000 plus dollars on?? YES. Even if these people don't win it will make these chumps at GM sweat and let them know the heat is on!!! Hell there has been like 5 threads on this very subject in the last week here!! People wondering what that sound coming from my motor when it's cold?? Remove the brand loyalty blinders and realise this IS a problem folks
WTF is with these people who are talking about "sue happy"??? 
This "problem" has been out there for years and EVERYONE was always saying "I sure wish GM would take care of this."
Sure, for most people it was not a "big" problem (a lot of people never even really noticed it) but some DID have it and they didn't like it (would like some way to fix it). What I don't get is that now that there is possibly going to be a way to get peoples cars fixed (or at least in THEIR eyes), other people (who don't have slap or don't care) are bitching?
Sounds to me like GM has some nut-swingers.

thats what I did.........after the head/cam swap and headers/true duals, I couldn't hear my piston slap anymore 
but then again the piston slap never worried me much (always planed on a rebuild some day)

I’m anxiously awaiting the day that someone files a class-action lawsuit against opportunistic, scumbag lawyers. The plaintiff class should be everyone whose cost of living is higher than it would be in a world free of these vermin.
