I just got word from the dealership today that my LS7 engine in my 2012 Centennial Edition was toast. It had 10,201 miles, give or take. They told me the reason that the motor seized is because of the #5 & #6. There was shaved metal in the bottom of the #5 head. I don't have all the exact specifics because the tech was out sick today. I stopped by and took some pictures.

WOW, that really sucks, was the car bone stock?

Thank GOD that your bumper to bumper warranty will get you all fixed up assuming your pretty much stock.

Best of luck to you.

Sorry man.

Good luck with the repairs.

slacker1201

Car was stock except for cold air and exhaust. Considering a price tag of 15k, I am very thankful for the warranty.

Gary '09 C6

the carnage doesn't seem to end...sorry to see/hear this OP.

G-L with the repairs, and I agree glad you have the warranty.

Crap

Keep us updated.

Unbelievable that a new motor can let go that early

GM is shipping a new motor. The dealership told me about two weeks to get everything done.

Coming from the ZR1, I took the gamble on the LS7 and obviously lost. Having a new motor put in my car, is this going to hurt value?

Gary '09 C6

IMO it's really hard to tell. Like it or not, the LS7's reputation has been tarnished by all of its reliabilty issues we see described/discussed here on the CF (and maybe elsewhere as well ?).

I've argued previously that the value of a Z06 that hasn't had the valves/heads repaired should only be diminshed
by the cost of such a repair, without additional upgrades, etc. So what is that, $3K to $5K ?

But, that might only apply to someone that wants to own a car equipped with the LS7.

You're getting a brand new engine. Make sure all the accompanying repairs (oil system & lines, oil cooler, etc.)
is done thoroughly & properly, and get back on the road. And IMO, extend your warranty with GMPP for as long
as you can.

I think GM should pay for the extended warranty on all the LS7's, knowing that there "could be" a problem with them.

Thanks for the info. I will give an update once things get buttoned up.

I like your idea of extending the warranty on all LS7s. However I am not certain anyone at GM would agree.

Have they given you a diagnosis any more specific yet? Probably not as the tech was out today, but it would be most helpful to know what part failed rather than just that it failed.

Good Luck with the Repair and Sorry for Your Loss. I know it sucks on a virtually new car.

I think we all kinda feel like we are playing Russian Roulette with the standard 1/6 odds of failure.

I have a 2013 Z06 with 6000 miles on it. I have read so many stories on here and I talked to me buddy that is a performance tech at a Chevy dealer about it. He told me not to worry about because he really hasn't seen that many problems with them. They are the biggest Corvette dealer in this area. I'm not really worried about it because I plan on trading for a C7 Z06 or whatever they call it. Sorry for your bad luck buddy...

That's sad that the car is jacked up like that. At least you'll have a new engine w/ 0 miles on the ticker. On top of that GM I not screwing u over.

Yo know what they always say..1 bad experience everyone hears it, 1 good experience no one hears it.

chrisfromalbany

compare this to mustang forum I used be member of.. just on sheer number of threads.. there more bad experiences with Z06 and valves compares to 5.0 and cylinder #8 failure.. just saying..

tim414

totally...

Other manufacturer's which have units with particular failures (such as CVT trannies in Nissan's) extend warranty periods for the particular item that's failing to often.

Seems to me GM would be better at quality control with the internal rotating parts to prevent this LS7 debacle. LS7's are really neat engines IMO, but there seems to be too many failures due to lack of quality control (parts suppliers of GM and GM for not looking more closely).

Sorry for your headache...

Mercedes extended my warranty to 10 years/150,000 miles just because they put in the owners manual to use regular oil instead of full synthetic, like what was supposed to be in the owners manual in the first place.

As for GM, I brought it up a year or two ago about them giving us extended warranties. If we are to believe GM, and the problem is nothing to be concerned about, then GM giving us extended warrantees would cost them practically nothing as they will have very few warranty repairs, since there is no problem, according to them.

Oh, and that extended warranty on my Mercedes. Didn't cost Mercedes a dime as the only time my car has been in for warranty repairs was because of a bad battery.

I think we're well past "1 bad experience" at this point.

Now the wait for how many more "fixed" engines will develop problems?

zcarbon

Yeap!

'06 Quicksilver Z06

That's going to be a long vigil Random.

But first off, I hope you aren't trying to lump all cars with cylinder head work into the category of "fixed".

If it's anything other than stock heads, manganese bronze guides, solid SS exhaust valves, polished intake valves, and a suitable valve spring for the setup, then you're talking about something other than "The Fix".

You've got something, but it ain't "The Fix".

Z06s in here with what is known as "The Fix" are among the most reliable Z06s that are in here.
