I'd hate to not fully enjoy the car for fear that it might explode. I know that every car has the potential to be a little sour but this one has a a fairly established tarnished record. I wonder if a Lingenfelter package would solve the problem.

It does not look that you can trust (or enjoy) the car any longer. I would fix it under warranty and sell it, get the '68 or another C6. Here's the million dollar question: How long has Chevy been building the small block now ? C'mon Mr. Lutz stop spending too much time on the Solstice (the car turned out fine) and fix the LS2 crank pulley issue.

My point in all this is if you get the warrenty as well as being backed up by lemon laws I see no real reason to dump the car at a loss.

Again this is just not acceptable on the part of GM.
The Corvette is the 'Flagship', but appears to be a sinking one.
What a mess.

My VIN is in the Crank Bolt Pulley range, but with 11,900 + miles, the only problem I've had is the "service active handling". Steering wheel angle sensor replaced at 4800 miles and no probs since then. I'm planning to buy a GM major guard extended warranty for piece of mind and to help resale if need be.
With 9 months and 11k miles I almost traded for an 06 Vert while it was still on the trailer. Even though I only owe $40k, the dealer was going to take my car without trade allowance and sell his at full sticker. Needless to say, I walked.
Nick, hope you get the problem solved for good. I've heard that pinning the bolt is the best real fix. I'd push for that.

I immediately bought another Z51 A4 and even though it's under the crank pulley VIN cutoff, I've had 19K trouble-free miles.

I was about to point this out. I was under the impression that once they fixed it, if it failed again with the diamond washer in place, you'd have to replace the engine because the washer would eat the end of the crank. Be careful and make them do it right!

I had a Corvette shop that was going to do the pin job( just cause I was worried) for 250.00.I still haven't done it but was told that is the absolute sure fire fix.Dave at Cartek told me that if the bolt was torqued properly you shouldn't have a problem.He told me he's had an underdrive pulley on his heavily modded car which was pinned and drag raced with it regularly.Now he has returned the engine to stock ( cams etc) and twin turbo'd it put the original balancer back on with the same bolt ( no pinning) and run's 10's at the track.If the job is done right you don't have it fall off.Yours may have had damage to the crank the first time which is why the fix failed.Thats the real danger of this problem. If it beats up the crank snout the fit could be wrong and the fix won't work but they're supposed to check .
