Sent you a PM the other day. Wanted to talk with you about it. Give me a call.

He has a thread on the general discussion area. It was a LT-1. But sounds very similar to the way my engine sounded. But his dealer test drove his like 107 miles or so. Mine want be driven around like that without a fire truck close by.

Not trying to stir the pot or cast aspersions on Jeremy's driving abilities, but I'm curious about whether this could happen by missing a gear? I've noticed the gates on my new Z are definitely closer together than my ZR1. Thus, it seems like missing a gear could more easily happen during hard pulls.

I ask because I'm wondering if GM could determine this and potentially void a warranty??

GM has some serious quality issues with C7. I would demand my $100K back.

Gotcha,

Thanks for the reply

IMO most motor failures fall into a very narrow class but with similar root causes such as torque discrepancies or lubrication failure for one reason or another.

There are exceptions such as back when "stroked" small blocks first became the rage but before "sandwiched" cam bearing became the known solution for successful cam bearing longevity in said motors.

Glad you are getting a whole new motor, IMO the wise choice.

Part of the 'data dump' from the ECU would be looking to make sure a 'money shift' hadn't occured. Since GM is honouring the warranty, no such over-rev event must have been found.

OP - sorry to hear about this. If they're willing to do a new engine, I'd go for that (plus new oil lines, oil cooler etc to make sure no metal bits floating around). Don't know if you can convince them on a new car.

My neighbor had the engine blow in his new BMW M5 - failed oiling/oil pump failure. He wanted a new car, but BMW refused and swapped out the engine for a new one.

Seems my story has gotten wings. Just got a call from my brother in Ohio and he isnt even a Corvette fan.

Again I must state GM has said they will handle this and I am willing to let them try. But If they dont know what caused it or how to fix it who is to say it wont happen again.

Also how do I get the info if this will show on Carfax. Some have said it will some said it wont. Indeed if it can be proven I will ask for that diminished value. Anyone that knows me know that I usually dont keep cars very long.

Sorry for this occurrence. No one should have to go through this.

You should really be getting a new car. I'm pretty sure you will have to disclose the engine replacement when it comes time to sell. As others have stated why start off with a diminished value vehicle with less than 1000 miles on it.

Driver negligence is never going to void the warranty. Federal (Magnuson-Moss Act) and state laws are very protective of consumers.

For a manufacturer to void a warranty they have to prove intentional misuse that actually caused the failure. If a manufacturer could void a warranty for fully foreseeable mishaps (ie missing a gear), our warranties would be useless. This is why the Uniform Commercial Code protected consumers with implied warranties even before specific federal and state laws were enacted.

Sorry to hear of your having this problem. To your original post regarding your two options, that reminds me of the high number of Pontiac RAM Air IV engines in the GTO that grenaded back in 69 and 70. Virtually all of them got new S.R. (service replacement) blocks under warranty. To find a 60 or 70 GTO with its original numbers matching engine is a rare thing indeed nowadays. The ones that seem to have them all came with automatic transmissions. Most of the blown engines were due to guys missing a shift and that engine was a high-revving engine anyway. There are too many nannies on these Vettes to let that happen now.

GM has a lot of experience over 100s of thousands of cars over the last 75 plus years dealing with blown engines. Yours, as frustrating as it is for you at the moment, won't be the last. I'm glad to see you are keeping a great attitude about letting them work the issue and get you satisfied. That is a great approach and I hope it all works out for the good.

BJ

While making a pull from 35 mph I accelerated and shifted short of redline and boom. Car began knocking. I pulled over and popped hood. Could hear a loud knock coming from # 6 cylinder area along with a serious grinding metal on metal sound coming from the supercharger area.

Had Gm roadside service come tow the car to the dealership. Beware gm will only pay for 25 miles. My dealer which is the closest corvette certified dealer was over 40 miles away. I had to pay the overage of $40 out of my pocket. I will be fighting with GM over this one.

Dealer called today and said there was indeed failure in #6 valve train. They were instructed not to tear into the engine because it needs to be evaluated by them.

They gave me two options.

1. Allow Gm to take apart the engine and patch repair it. This option would of kept my original numbers matching engine in the car.

2. Replace the engine as a whole. This was the best option in my opinion due that I track my cars alot. I dont want any more issues with this engine.

So dealer went ahead and notified GM to send another engine. Who knows how long this will take. I really fell bummed out with GM right now. Sure this is a first year car and I understand that. But this is not the first time I have had to do R&D for the big GM. Just last year I was the first private owner to track my C7 Z51. That car over heated on a November cool day down here at Road Atlanta. Both the Transmission (M7) and engine. I made a post here and notified the engineering dept through my dealer. No one even followed up or cared.

My biggest surprise of this situation is that GM wasn't surprised at all about this situation. Seems this has occurred before with the test fleet vehicles.

I come here and post to not to bash GM but to warn you fellow Corvette owners before you go out and tune or modify your cars. Sure this may of been a issue in just a few but there was alot of looking into my computer files and such to find any mods. Sure GM would love to not have to pay for this $23,999 engine.

I will keep this thread update. Please please trolls dont destroy this thread with useless comments.
The car I ordered and cancelled arrived at the dealer today. I saw it while I was there and was almost about ready to change my mind again and take it but this post just gave me the *******. On further thought, I wonder if the apparent ECU issue was meant for a reason after seeing this. It would not be unusual for technical management at GM to place intentional limits on this car in the early production models because they have an unfielded system and everyone knows it will certainly have teething problems of some kind. You need to know things like how well your suppliers can deliver quality materials, or how the user will operate the car, or if you covered every potential risk in the production cycle. By intentionally degrading performance you can find and correct problems before they become catastrophic, especially to the brand. Once early errors are found and corrected, in time, the ECU thing can go away.

Sorry for your headaches lawdogg. And I feel sorry for the guys at GM of whom I'm sure many are working diligently to field a car under the stress of getting the job done right under the pressure of saving their livelihood and the brand.
