Does the factory warranty really cover the motor for 5 years though? I am pretty sure I saw it covered it for 1 year. Thats why I bought the extended warranty for $1500. Well, I am covered for 5 more i guess !

FWIW, I now have almost 16,000 miles on my '07 Z. I autocross it, and have tracked it, while pushing it pretty hard. I also drive it aggressively whenever I get the chance and I have had no problems for almost two years now, except for the fact the rear tires are wearing faster than the fronts.

ls2gto06 - As far as I'm concerned, my dealer assurred me just as the warranty book indicates, my 2008 has a 5 year, 100,000 mile drivetrain warranty. That being said, it is my understanding that GM is becoming intolerant of modifications on warranty claims. Non-drivetrain mods should be OK, however. So I'll think I leave the powertrain system as is for the time being, at least until my driving skills reach a much higher plateau. Have fun, drive the wheels off it, do the required maintenance and good ol' GM should keep their end of the bargain and stand behind it, (Well, I hope so !!)
Running into similar problems. Glad that you posted the sheets. Thank you. Car has 2500 miles on it and has had a clicking sound coming from the engine ever since I picked the car up. At 1000 mi they told me to drive it for another 1000. At 2000 mi I called the dealer and now they are trying to figure out what they are going to do about it. They told me about the engine replacement program, and I suggested if they wanted to go that route, they might as well just call the GM area rep and find me a new car.
Hard to replace the heart in someone's body and tell them everything will be good as new. Just my $0.02.
Still waiting to hear what the dealer comes back with. 10 business days + 5 days transport time equates to somewhere between 19 - 21 calendar days out of your hands.

Silver Ghost, I feel your pain. My vehicle went down just before the July 4th weekend. My car sat at the local dealership for 2 weeks because the corvette plant is closed the first 2 weeks of July. It was finally shipped to the GM plant around July 20th. I was told late september, early october I could expect my car back. This was due to toher cars ahead of mine, and GM's limited personel that deal with this problem. I called the plant yesterday and left a voice mail to check on things, and have not heard back yet. I sure hope it goes faster than they predict. The chevy malibu I've been driving just isn't quit the same.
Sorry to hear about these sort of problems. I'm sure the owners are going through a helleva an ordeal. Personally, I think they should be entitled to something REALLY nice as far as a warranty claim rental car; perhaps a base model Corvette "demonstrator" off the lot. A Malibu isn't going to cut it. The monthly payment I'm making on one of these cars is astronomical, so I think GM should waive the payments (prorated) for the time a Z06 is under a length warranty repair such as a defective LS7 engine replacement in BG. Make even get Chevy to pick up the tab for your insurance coverage, while in for the repairs, but good luck getting that one!
Frankly, matching #s probably don't amount to a hill of beans when we are talking about a particular model year Corvette built in fairly significant volumes, and certainly won't play a role for at least 25 or 30 years later.
I too would rather have a brand new replacement engine handled by the Bowling Green Assembly Plant. I think they would have the best trained people to do this kind of repair and "retest" procedures. I would ask your dealer to document the mileage in/out of the repair process from beginning to end to make sure there are no unnecessary (or unauthorized) miles added to your car in the process without your express consent.
Anyway, I'd be interested to know exactly what the "cause" of these failure were, so please keep up up dated. TIA and good luck!

I hear you. I surprised they told you 2+ months. Here in CA if I had to wait that long, the car would automatically become a lemon. 30 days out of my possession for dealer/Mfr repairs in the first 18 mos or 18K miles qualifies it.
Check out the Local warranty laws for Louisiana here http://us.bbb.org/Storage/16/Documen...-LLsummary.pdf. If you're still waiting on your car now, you may just lob a call into the customer assistance center and ask them to simply replace the vehicle. That kind of wait is completely unreasonable, especially when the TSB states that the repair should be complete in 10 days.
From what I see on the doc referenced above, it looks like the rules stipulate the following for Louisiana:
"The manufacturer must repurchase or replace a motor vehicle (other than a motor home) if either of the following occurs (Note that the lemon law also provides for a presumption that a reasonable number of attempts has been undertaken to conform a motor vehicle (other than a motor home) to the applicable express warranties if, before the expiration of the warranty or during a period of one year following the date of the motor vehicle’s original delivery to a consumer, whichever is earlier, either of the following occurs
1. The same nonconformity is subject to repair four or more times by the manufacturer, its agent or authorized dealer; or
2. The vehicle is out of service by reason of repair for a cumulative total of 45 or more calendar days.
So if your car has been gone for more than 45 days, which it sounds like it has, you may have a lemon on your hands and a good case for a replacement vehicle from the customer assistance center.
You've been a good sport about this up to this point. Time for the General to make you whole.

If that's the case, I'd definitely lemon law it. You would get it all back (assuming you bought it new), less of course a small fee for usage based on the mileage at the first repair attempt. Definitely not enough to eat up the extra $25K over what you could buy the same car for now.
Final status on the ZO6 from Shreveport. Received the vehicle with the new engine replacement. Went to the dealer, started it, and the engine started smoking and sputtering. Found out the plant put 10 qts of oil in an enegine that only require 8 qts. I gave them a chance to clean it up, but the car will not run without the engine light coming on or choking upon starting the vehicle. Appearantly the air intake was contaminated with oil as well as all the sensors, and all the spark plugs reportedly bad. Nonetheless, they can't seem to fix it. I have been out of my vehicle for 66 days since june 30th. Can you say lemon? The answer to your question is yes. I have begun conversations and paperwork to have them buy the car back. The vehicle has a total of 7700 miles on it. I purchased the vehicle for 70,500. I am told I should get most of that back without too much depreciation. Does anyone know of any use Hummer H2 for sale less than 2 years old? I now have a 3week old and 18 month old. I may wait 3-4 yeas until I buy another corvette, although that is all I have driven for the last 8 years. I will miss it.
Wow! This is a pretty crazy thread. I did not know of these kind of problems for the c6z. Sorry to hear about them ruining your second engine docjcs I would be pissed. Hopefully you'll get your money back.
Someone mentioned in this post that maybe whoever the builder is of these engines should be noted. It could be the same person or similar pattern.
K M, it might be interesting to note the name of the LS7 builder(s) in such cases, but for the most recent failure, it sounds like somebody in the Bowling Green assy plant screwed this owner's 2nd engine. Since the dry sump oil lubrication system has an "external" resevoir, I think the factory fill, even for a warranty repair, would be done like all other newly built Corvettes during final assy of the car.
IMHO, whom ever did that should be removed from his or her position on the assy line, retrained or transferred out. That same person could of over filled several other cars just the same.
The major change from the '08 to '09 Z06 was from 8 to 10.5 quarts in the dry sump lubrication system. It may be that only the external resevoir tank capacity changed, not the engine. So, in this particular case it is possible the car owner got a "new" engine (i.e. one built or intended for use in the '09 production model year, but his car being an older model still had the smaller resevoir tank.
Nevertheless, it is inconceivable (if not completely unprofessional) that such an elaborate warranty repair procedure would be done by "trained" personnel w/o a simple revalidation test at the factory before returning the car to the field. However, from a "design" standpoint, something obvious should have happened while attempting to overfill the resevoir by TWO FULL quarts to suggest it was being overfilled. Like oil spilling all over the place out of the resevoir or upon initial engine start.
The scary thing is the same thing could happen to any of us if we (or our servicing dealers) are not VERY careful changing the oil.
The LS7 comes with titanium valves made by Del Webb, excellent name known for quality...but there have been several (not common) that have failed. These have been all intake valves cracking & breaking, dropping into the cylinder & then the parts ussually will bounce to several other cylinders (by being sucked through the intake to the other holes) damaging several pistons & sometimes cracking a sleeve or two. These appear to just be material defects of random intake valves, but the results are devastating. We will have to watch & see how isolated this is, but to date it appears it is rare.
I would be curious from all the people that have experienced these engine failures if their car was completely stock with the factory tune etc or what mods. I personally don't care how hard the car is driven, just whether or not they will hold up to mods and then driven hard. In 1996 I experienced a warranty denial from Ford when there was a pulley change on a Mustang Cobra engine and have therefore shy'd away from mods on any vehicle with a warranty. I was also told by my dealer that by purchasing the extended warranty directly through GM that I would have a much better chance of getting attention if there were something to go wrong.
Could those with engine failures chime in with Mods / No Mods?
Also, if you have a tuner flash your ECM and then return to stock at some point, is there evidence of that left?
