My wife called the lawyer and faxed him all our maintenance receipts. The lawyer sent a letter and followed it up with a phone call a day later. The general manager called my wife and said they had reevaluated the issue and they were shipping in a new motor ASAP.

If you have any motor skills it may be a great experience rebuilding yourself. If you don't, find a friend that does and take the opportunity to learn.

Replace the cast hypereutectic pistons with forged pistons and tool steel wrist pins. Also replace the 2-piece exhaust valves with quality one piece valves and the steel valve guides with bronze guides.

Best of luck!
Anyone have the contact info for a good lawyer? Please PM me with details.

You will need as lawyer in your state familiar with vehicle warranty laws. Start with the phone book. Might want to avoid the ambulance chasers.

Another method would be to join Pre-Paid Legal. They will usally not take a pre-existing case, but you haven't done anything yet, so you may be ok.

Where did you pull that 100 number out of?
How many were bone stock, how many modded?
What percentage is your number compared to production totals?
Inquiring minds want to know.

my brother works for GM and they have been instructed to "good will" just about anything...even cars way out of warranty. All to improve customer satisfaction. Call GM corporate..go above the dealer and see what you can get.

if none of that works...sell me the car (i'm serious) then sue GM for diminished value

I don't doubt your post but he did have an "aftermarket" tune. Good will or not, I say GM won't warranty it.

these cars have so many sensors and protections built into them that a bad tune is not going to cause a valve to drop without throwing a code on something else first...i would argue that if no old codes existed in the computer like the knock sensor going crazy months before the motor grenaded itself then the motor should be covered.

i think its just a bad dealership.

warranty is just like insurance and an insurance adjuster first learns how to say "deny claim" before "here is your check"

I would rebuild a bad azz Heads/Cam LS7 engine into a nice heads and cam engine making around 550 to 580 rwhp.

It doesn't hurt to consult with an Attorney but with a Hypertech tune in it, it is my humble opinion (not legal advice) that you will be SOL.

Best of luck to you!

Last Spring my wife bought herself a nice foreign made SUV. I won't mention the name but just say that it has a VERY long warranty.

Well, today we received a notice from the factory that there is a potential problem with the front springs that could cause premature failure. Apparently they learned this from repair reports and analysis of the failures. Smart eh?

Anyway, I guess to minimize their future warranty repair costs and maximize customer satisfaction they are calling on all owners to bring their vehicles in for a no cost upgrade to fix the DESIGN problem.

So why would I mention this here? Wull, are there any design flaws in the LS7? I dunno....kinda, sorta appears maybe some problems with the valves? Like kinda, sorta maybe they would have figured out the problem from all the failures?

You see the difference between approach "A" with the foreign manufacturer and approach "B" fix it when it fails unless we can avoid it?

I dunno. We're probably going to take the SUV in for the upgrades. The manufacturer has admitted a design flaw, found a solution, and is going to do the upgrade for no cost. Who is leading who in the business world now? Seems like we need to be sending MBA students to this foreign country to learn how to proactively manage a business instead of letting accountants and executives being paid quarter to quarter bonuses make the decisions.

Or maybe I'm wrong and there's nothing comparable here at all?

Besides, as one post said, there's nothing wrong with the LS7...just a few isolated failures...no pattern.

Do you know for a fact that a "bad tune" won't grenade an LS7? If so, maybe you can send your info to the OP so he can argue with GM about it.
I don't know if it can or can't. GM basically says that they will warranty the powertrain for 5 yr/100K miles IF you don't mess with the tune. In my case, the warranty is worth more to me than a few extra HP by messin with the tune. Others may want the extra HP and are willing to risk the warranty.

In my opinion you are wrong. A spring failure is a safety concern and they issued the recall to prevent accidents, deaths, and lawsuits, not purely for customer satisfaction.
