I am a first timer to this forum and have ben very impessed with the information i have seen written.
Last night at 100mph i lost a belt, looked under the hood and saw the pully about to touch the rack and pinion. Of cours i started top panic because i have only driven the car 1200 miles. Today i looked for other owners with this problem and found this forum. I have not contacted a dealership yet does any one have new information about how to handle this problem.

automatic or manual?

I am curious regarding what happened to your car. You say last night at 100 mph.........what was the aftermath? You stopped and saw the damage and did what---drive it home---get it flatbedded? Where is the car now and is it driveable? I re read this entire thread when I saw it---when it happened to me I was more than mad--then it happened again---but it is fixable---more now than before---if it is not at the dealer now you should get it there. The c6 has crank pulley issues and the factory treats them like ''isolated incidents'' which is not the case at all.

Sorry for your inclusion to this tiny little club.

1.Call the Chevrolet Customer 800 number,800-222-1020 so you can begin the documentation process. They will pursue a resolution starting from the other end and may help speed things along. They will assign you a case number.
2. Get the car back to your dealer so they can impliment the correct fix.

Let them do their job of course, but at the first sign of confusion on their part you will want to be actively involved. My dealer was great IMO but some here have different stories.

I think the 800 number thing worked great in my case anyway.

Good Luck

One belt came off, Pulley is just about off, Oil is coming out of the front of the engin. It felt like a wheel was coming off so i pulled over, with the engine running I opened the hood and saw the pulley doing a dance ( not good ). Called a flatbed. Car is not drivable, it will start and runs OK, but you cant drive it. This happened on Saturday night, Sunday no dealerships are open so I found this website and it made me feal a little better knowing i'am not alone with this. Of course my first thaught was i have waited a long time to by a car like this, how can this be happening to me. Second thought was how much fighting will I do with Chevy to get this fixed to my satisfaction not theirs. I have written to a well known corvette performance shop ( www.motorsportimage.com ) asking their advice on how the repair should be done, fix it or replace the engine. If you replace the engine how does that afect the documentation of the car. I will post all information as I get it. Because without this forum I would have been on my own.

I think you will find it can be fixed. I do not worry about mine anymore some 4,500 miles since my dealer fixed it.

BTW you won't be the last person having this issue until all 9000 or so that were built prior to the Julian date have had the fix. There might be some that never come apart because they are driven very sedately by their owners but eventually I think they will all require the correct fix.

So far it appears that there are 10 verifiable cases at least in here CF.

Let`s hope that not all 9000 or so C6 prior to the Julian dates are affected.

Yeah, we all know GM fixes their problems right away...............not.

I still tend to think that the bulk of the cars are not affected by this. I might be wrong, but I would have expected many more failures by this time if the problem was due to a bad part or lack of the washer.

GM now has a fix for this, but I don't think they really know why it has happened at all. If spirited driving alone were the cause, the bolts would have certainly loosened during all the high speed testing that was done prior to production. Most of us do tend to push our cars...I don't think many C6 owners drive their cars like family sedans...I know I sure push mine. In spite of this, the vast majority of owners haven't yet experienced this failure. I think something else is going on here, like random assembly errors at the plants that produce the motors.

Until and unless GM issues a recall, all we can do is watch and wait. I don't think a dealer will take on the job of installing the new washer on his own without at least a TSB or some sign of belt wear on the individual car.

I, for instance, only have 200 something miles. It wouldn't show up yet. But read the other interesting thread.

This was just posted in CF/GD and will hopefully put to rest any questions on the subject.

Has the crank pulley problem been fixed in later production C6s?

BOG1E

That was a Friday, this kind of lends a little credence to not buying a car that was built on a Monday or Friday.

Could someone let me know if I need to be concerned or not?

My VIN is 110416.

hawaiianswiss

The engine was built prior to the car build date.So I guess this has nothing to to with it.

hawaiianswiss

It was stated that all C6 prior to VIN 111039 could be affected.So your car was also built before that VIN.I would mark the crank pulley with a paint pen and monitor it from time to time.

Rob4092xx

Thanks!

Exactly how/where do I make this pen mark?

The very first post to this thread is a report of the crank pulley coming loose at 183 miles.

hawaiianswiss

Raise the car in the front and locate the crank pulley on the lower part of the engine.It`s the big black pulley in the middle in front of the engine.Take your paint marker and mark the pulley and the bolt in a straight line.
Now you can monitor if the bolt is loosening.If your paint mark on the bolt/pulley doesn`t match anymore go to your dealer as soon as possible!
