So I would only trust it to a dealership, or someone like MTI, etc. One guy here was able to get his dealer to do it pre-emptively. Maybe you could loosen the nut a bit (I don't know how hard it is to get to) and then take it to Robbins ?
If you see the "check engine light" come on during driving this would signal the problem and you would need the fix.

This is not a new issue with the LS1, and LS2 engines...this problem has existed since the engine was put out. First off, there is no key way on the crannk and balancer, press fit. If you torgued the engine up on a a regular basis, it will come off....sooner or later. Take the bulletin into your respective dealership, with the car of course, and just say, FIX THE DAMN THING..NOW. it will get done......or wait until you just happen to want to get down on it a little, then it will fix itself...KA-BUMM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!1

Until they do a recall I will not change my avator. Mine went down at the 300 and down again at the 600 mile mark. First fix did not include the right washer. My car was one of the earlier ones to fail and the information was not readily available as it is now----17 days in the shop. There are about 11,000 c6's at risk for this and still no recall. Good luck .

Its a hard to fix problem, thats for sure
I just read the repair tsb to fix the problem. Its much more than just putting on a diamond washer and then torquing. Heres the post I read.

It reminded me of the column lock problem. After the car went out of warranty GM was charging 500 dollars plus to fix. Finally enough complaints from us caused a recall to disengage the faulty unit. At least the column lock didn't cause any damage to the rest of the vehicle. P.S. I remember watching my baby going up on the tow truck bed too.

Not hurt, thankfully, but IF my wife had been driving, I do not think she would have had the strength to steer herself out of trouble..........you really need to know how BAD I-4 is here in FL. Perhaps some of the FL members can tell you had bad it is to drive..............
I emailed the Customer Service Center and received a email back AND a phone message from a very concerned representative who stated that "addressing this issue is very important to me"......................we are currently playing "phone tag".

I was at Summit Point Raceway this past Friday, and a brand new Vette owner (his first Vette) was there (first time at Summit) with this C6. Gorgeous car. Part of the way into his second track session, he heard a deafening *THUMP* and had to fight with the steering to get the car off the track safely.
After the engine cooled itself down (it'd sprayed DexCool everywhere,) he started it back up and man-handled it back to the pits. I took a look under the hood and saw exactly what the original poster saw: shredded hood liner and frayed belt.
None of the area Chevy dealers had the belt in stock. But my mind kept flashing back to the Corvette Forum, and his problem seemed so familiar for some reason. So I guess it's a good thing he couldn't find a belt, else he may have "fixed" it and driven home. Fortunately for him, his buddy was there with a big pickup and a flatbed trailer. So the C6 went home on that. :-(
Not a good day for a first-timer at Summit Point. Nor a first-timer Vette owner. What a bummer.

Good Dealer in CT
Does anyone know a good dealer in CT who will do this repair. My Vin is 108557. I'm heading down to FL on a road trip thursday and would hate to have this happen at all, let alone many miles from homebase..

Does anyone know the who we could or write to at GM to complain about this issue and put pressure on to get it changed to a recall? Perhaps NTSB or whatever they are called (Government traffic safety board, or whatever). It does appear to me to be a very real safety hazard.

That is for an automobile safety complaint... you can fax it, phone it in, or submit electronically.
The safety aspect is of course the loss of power steering and controllability, especially with slippery coolant loss!
Good luck!
Two complaints so far to the website (obviously forum members!!)

My dealer basically told me on a program like this they cannot be reimbursed for fixing it unless the damage is already done. Anyone who can confirm or add to this I would appreciate your thoughts. Also, how hard is it to actually replace the bolt/washer if one were to pay for it themselves (or can it be done by a shade tree mechanic?). And are there signs we can watch for to see if it could be comming loose? Thanks!
Good luck getting this fixed.

One thing that I'm a bit perplexed about is why the belt does so much damage when it comes off. Belts come off cars all the time and I've never heard of this shredding things and causing oil/coolant leaks. Why is it so bad in this case? Also, why do so many report oil/coolant leaks. What exactly is the belt taking out when it comes off. I would think that normally a belt coming off is a relatively minor thing.
