not necessarily The roof still clips in as well, it's not just glued in

 

if the roof comes off, and the fix is to glue it on, seems to me that it's the glue that's holding on the roof?

 

I've seen the worst use of that on a couple S2K's recently. I hate when (shitty) techs use that stuff around the valve cover. They get all messy with it. I think the difference between hondabond and the GM stuff is that I know Hondabond sticks. Ever tried to crap open a valve cover that has had Hondabond applied?

LOL @ the Porsche comment

I can never recall EVER hearing a build quality complaint about Corvettes.

 

dont think its that big a deal.

 

Not a BIG deal but when body panels are flying off...... then theres some concern.

 

That was suposed to be in red text, right ??

for 2001 Z06 piston slap oil consumption

But in fairness, they do take care of the problems when they do come up (not like some companies **cough** transmissions**cough**)

 

As Scott probably already knows...this ended up on 6speedonline too. Even the P Car guys are laughing at this.

 

nothing is sacred at General Motors!

 

This is some what interesting to me. Though I can't say categorically but I feel confident that if Acura, BMW, Mercedes, Porsche et al had built a performance version of their "C6" they would have likely designed a purpose built roof that would have been more elegant and functional the the permanent targa section bolt in job. I know GM had to meet tight budget concerns but I seems clear they could have had a lighter element at the top of the car and had to avoid it due to costs. Now understand this has NOTHING to do with the cosmetic roof panel flying off just something I didn't know about the C6 Z06 which reminds me there are no free lunches.


As an aside consider Z06s on the track at HPDEs etc, they don't have to be worried about getting blue flagged because I don't know about anyone else but if I was on track with one in front of me and I had the power and skill to get the Z06 blue flagged I would think long and hard about pulling up behind one at 120+ MPH...

 

There is a TON of misinformation in this thread.
I guess much of it is because you guys are unfamiliar with the construction on the C6.
It’s a PLASTIC bodied car over a metal frame, of course there are a lot of adhesives used to hold it together.
The problem is that the adhesive used to hold the roof skin to the frame of the removable section became brittle and allowed the two surfaces to separate.
At high speeds air could get under the panel in the front and off it comes.
Lots have been repaired, but I think the number of roofs that have actually flown off is in the single digits.
Usually excessive squeaking and popping sounds from the roof are an early warning sign that there is trouble brewing.
The roof delaminating problem is mainly with the 2005 model.
There are very few (less then 100) 2006 VIN’s affected.
It’s not a safety issue with the structure of the car because it’s designed to be driven with the roof completely off anyway.
Although the guy following too close behind may think otherwise.

thanks for your take on this shawn but i'm not seeing where the misinformation is in this thread. i don't see how the fact that it has plastic boy panels dicates that you must use adhesive to hold them on the car. properly engineered fasteners should have been able to do the job better but obviously that would be more expensive. it's an obvious shortcut in the design of this vehicle and honeetly if i owned a c6 and this happened to me i would be more than a little embarrassed considering how much i'd have paid for this car.

 

 

wow spelling owns me

 

I think many here are being overly harsh on on GM and the Corvette here. Every car on the market has faults (especially early build models) and if you take a large enough sample size of course you will see issues.

Yes, it sucks that on a small number of Z06's the roof cover flew off, but as people always say, shit happens.

The fact remains that GM consistently fixes these problems that appear in a timely fashion unlike other manufacturers. Glue is commonly used on most cars and the plastic panels of the Corvette require it.

Look at my old 350Z. It had the front tires replaced twice, transmission replaced, rear axle replaced (all of which were VERY common issues on the early build models). It was a headache, but I expect issues on early model cars. GM is not unique in this regard.

 

Shawn said this too...why do you guys assume you have to use glue to attach plastic body panels? It doesn't make much sense to me other than just a cost cutting measure.

Also, I'm not saying the corvette sucks..just saying that i probably wouldnt buy one. Lets face it, a roof coming off a vehicle while driving down the road isn't your typical new car glitch. It's flat out ridiculous.

 

best post in there:

 

 

to clarify, i dont think it's a safety issue. it's more of an embarrassment than anything. how would you feel if you were showing your pimpin new car you just paid 50k for to your friends or a date and the roof flies off while driving down the road. You and your car would be the brunt of jokes for a very long time. i don't see why people are being apologists here...it's downright laughable that this is happening to a 50k$ car.

 

its a safety issue when it comes to other cars on the road swerving to avoid the roof flying at them - i.e. it could cause a serious accident on the highway, putting lives at risk.

 

true but that's not what i find particularly shocking about this issue.

 

I'd be more concerned about safety than being embarrassed. Being embarrassed in front of your friends? Haha what kind of firends are those? Shit happens. I'm sure we can faults with Porsche's, Ferrari's, etc...that are just as menial as this. And no i'm not finding specific incidents, just saying.

 

Using adhesive makes it STRONGER and QUIETER then fasteners.
This problem came about because the adhesive failed, not because it was a poor design.
If you attach a large panel like the roof to the removable frame with fasteners it will creak and squeak.
Plus if you add temperature into the equation it makes it even worse.
Now you have two dissimilar materials expanding and contracting at different rates.
Using a strong adhesive is just like you’re welding the plastic to the metal frame.

For people who say use fasteners, I’d like to hear you’re ideas on how you would accomplish this on something like the roof.
Sure on the fenders, doors & trunk it’s possible because you don’t have to hide the bolt heads.
But I don’t see how you could do this on a removable roof and hide all evidence of a bolt both inside & out and still make it easy to lift off and put in the hatch.
