I had mine done before it happened. Don't let it fool you if you are within the VIN range it will eventually happen. Yes part of the steering had to be dropped. The mechanic was a seasoned C5 mechanic. If was his first C6 Crank pulley. He installed the diamond embedded washer. Everything went back fine. Took about 5 hours. Drives straight as an arrow.

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

YES, MINE WAS CORRECTED AT 850 MILES....

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 .

Here's the the thread with the repair procedure - pretty serious stuff

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.

Any new car will have its aches and pains. Good luck getting yours repaired, it will be fine Just be thankful you aren't hurt.

VNAMVET

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.

This problem is not going away. The guy who had the belt go recently had over 5000 miles. Some have felt that if you make it past 2000 miles, you're good to go. I just don't think this is the case. Spring came today. Many vettes will start coming on the road. It will be interesting to see more posts on this subject. I hope nobody gets hurt (or worse) because of this.

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..

jschindler

The problem right now would be finding a dealer who will fix it for free. Are you willing on paying several hundred dollars to have it fixed?

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.

#3376, 4,000 miles...so far, so good

Bubbabow

I think i understand what this is but could someone be more specific - what vin range of numbers are we talking about

OttoNP

I wouldn't take my car in unless the issue occured. A dealer is far more likely to screw something up with all that is involved in the repair.

Guys, if you've had the problem, and I've seen a couple of new names here, please vote in the poll so that we can keep this thing well documented here.

I have done that this AM through email:

docrings1

http://www-odi.nhtsa.dot.gov/ivoq/

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!!)

Summary:
(1) PURCHASED CAR 10/23/2004. (2) ON 10/24/2004, LESS THAN 24 HOURS AFTER PURCHASING THE CAR, THE CRANK PULLEY "CAME LOOSE" AND THE CAR THREW ITS SERPENTINE BELT (LEARNED AFTER THE INCIDENT) WHILE DRIVING ON A CROWDED INTERSTATE. THE FIRST INDICATION OF A PROBLEM WAS WHEN THE DRIVER INFORMATION CONSOLE (DIC) DISPLAYED A MALFUNCTION WITH THE VEHICLES CHARGING SYSTEM THAT NEEDED SERVICE. VOLTAGE DISPLAYED ON DIC DROPPED QUICKLY IN .1 VOLT INCREMENTS UNTIL ROUGHLY 11 VOLTS WERE DISPLAYED. THEN, THE CAR BECAME INCREASINGLY UNRESPONSIVE TO DRIVER INPUT FOR STEERING AND THROTTLE. BRAKES FELT "MUSHY" BUT CONTINUED TO RESPOND TO DRIVER INPUT. ALTHOUGH THE DASH DISPLAYED A FRIGHTENING NUMBER OF ERROR MESSAGES AND ALARMS, THE OCCUPANTS HAD NO IDEA WHAT WAS THE MATTER WITH THE VEHICLE. TRYING TO CROSS 5 LANES OF PACKED FREEWAY TRAFFIC TO GET TO A SAFE BREAK DOWN AREA, IN A CAR THAT APPEARS TO HAVE LOST ITS MIND AND IS SPRAYING ANTIFREEZE ALL OVER THE HIGHWAY, COULD HAVE EASILY RESULTED IN INJURY OR DEATH. WE WERE VERY FORTUNATE THAT WE DID NOT CAUSE AN ACCIDENT. 3) VEHICLE WAS "REPAIRED" AT OURISMAN CHEVROLET IN MARLOW HEIGHTS, MD. CRANK PULLEY, BOLT(S), SERPENTINE BELT, AND UNDERHOOD INSULATION (DAMAGED BY FLYING BELT) WERE REPLACED. A FRICTION WASHER WAS ADDED BEHIND THE CRANK PULLEY ON THE ADVICE OF GM TECH SUPPORT. *CAR BROKE DOWN AGAIN WITH THE SAME PROBLEM ON 13 NOVEMBER. CAR IS NOW AT RADLEY CHEVROLET IN FREDERICKSBURG, VA. GM HAS ORDERED THE MOTOR REPLACED AND THE DEALER IS AWAITING PARTS. THIS IS NOT AN ISOLATED FAILURE, THERE ARE OTHER LS2 ENGINES BREAKING DOWN BECAUSE OF THIS CRANK PULLEY PROBLEM.*AK

Summary:
COMPLAINT RECEIVED VIA E-MAIL. MY 3 DAY OLD CORVETTE SHREDDED ITS SERPENTINE BELT, OVERHEATED, AND LOST ITS STEERING. CAR HAD 300 MILES ON IT. FROM WHAT I HAVE BEEN READING ON 'CORVETTE FORUM THIS WAS NOT AN ISOLATED INCIDENT BUT HAS BEEN OCCURRING IN TOO MANY NEW CORVETTES. THIS PROBLEM COULD AFFECT THE OPERATION OF THE VEHICLE AS IT NOT ONLY AFFECTED THE COOLING SYSTEM BUT MORE IMPORTANTLY THE STEERING AND BRAKING. TO MAKE MATTERS WORSE THE REPAIR OF THIS PROBLEM WAS FAILING ON MANY CARS, AND THEY WERE EXPERIENCING IT FOR THE SECOND AND THIRD TIME. *AK. *AK

The early signs on mine were sounds coming from the belt. It sounded just like a wet fan belt does when you accelerate. The weird thing was that it rained on the day the noise started so I thought that was it. After that things went downhill. Mine was reapired 4000 miles ago and everything is good.

What a bitch.

mikeyc6

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.
