It's at Young Chevrolet in east Dallas right now. Was told they'd begin tear down next week sometime. I'm expecting that they won't cover under warranty because of headers and likely tune. Will try and involve chevy customer service if they aren't willing to help. If those things don't work, maybe the block is fine and it'd just need a rebuild..?

Seems like many of the failures I have read about got new block too though.. however it isn't always necessary though, correct?

Headers and high-flow cats aren't going to void your powertrain warranty! GM would have to prove the engine failure is a direct result of those mods. The tune (if there even is an aftermarket one installed) might be more iffy depending on what actually failed. A good dealer would and should go to bat for you. I'd press for warranty coverage.

As someone who has had to replace a corvette engine, my heart goes out to you, buddy!

At what point in that post of mine, did I claim On Star blew the engine?

At what point did the OP, in posts previous to this actually confirm the engine was blown?

Loss of power, funny noises, complete shutdown requiring a tow, it might be a blown engine, or it could be a an electronic failure, or, perhaps, it could be someone shut it down remotely; as I suggested.

I have yet to see a post (24 posts so far) confirming a blown, or seized engine.

I'm not saying the OP is wrong about his powertrain pyrotechnics, but here's hoping it's a software glitch.

I see from your subsequent post that a dealer is going to investigate and see what actually happened. While it's hard on you to wait on this, anything we say in advance really is a guess. Get some hard information and then you'lll be better equipped to know what to do (and how serious the problem really is).

Good luck!

How many miles did you put on the car since you bought it, and how did you drive THOSE miles? It probably wasn't the last ten miles that hurt the engine. A part weakened by previous abuse could have failed during normal use.

Good luck with the repair - sorry to hear about the problem with such few miles on the car.

They cannot void the warranty, but they can deny a powertrain claim on a given repair due to modification.

I have owned and been on a lot of enthusiast car forums and one thing they have in common is when it comes to powertrain modification, people say it's on the dealer/manufacturer to prove the modified part caused the problem but the vast majority of the time it just does not play out like that in real life. And the Magnuson Moss Act was never intended to cover issues like this. Right or wrong, when someone knowingly replaces a perfectly good OEM part with an aftermarket part with the intention of improving OEM performance they better be prepared to accept a warranty denial.

I feel for the OP on this. I hope GM covers him or at least helps him out. But as they say, pay to play.

Correct, it doesn't play out that way in the real world because the only remedy one has under the MM statute is to sue a manufacturer in the event of a warranty repair denial. It's a civil suit, where the burden of proof is on the plaintiff, AKA the customer, to prove his/her modifications did not cause the failure.

Then there is the tremendous cost of fighting a manufacturer in court when they are holding all the cards, with a treasure trove of engineering data. Lastly, read your warranty agreement carefully. It was agreed to when the the car was purchased, and the terms were violated with many of the mods being discussed here. That almost always wins a court case for a manufacturer.

We're not talking about aftermarket replacement mufflers and air filters here, which is what MM was intended to allow, along w/ not having a warranty denied because you had your oil changed at Jiffy Lube.

I have a short block out of my 2017 Grandsport I will sell cheap if you end up needing it.

Sounds like when my 15 Stingray had a lifter stick and took the camshaft out with it. Weakest link in the LS engines is that crazy active fuel management system.

I feel your pain. I hope this is not one of the 100,000s of flood cars that will hit the market. good luck

I don't mean to be persnickety, but LT engines, not LS. I don't disagree with you, however. I do not drive in D because of the AFM.

ncstingray

Thanks for correcting my knucklehead engine mistake. My 15 didn’t have a D gear since it was a manual. I did stay out of ECO mode.

Is AFM really a reliability concern at this point?

LT1pwrd'94

I've put about 1,200 miles on it... easy miles, think I hit 5000 rpms once.. 5300 at most

This car was in Dallas before Harvey hit Houston..

Here's all you need...I've been using this for a few months and now enjoy a full-time V8 engine.

Except when I am on track, I run mine in Eco Mode most of the time.

I do too on open freeways, and the only way to do that in an M7 is in Eco Mode.
