From a Corvette friend of mine and ZR-1 owner...

How are you these days . Say this Corvette guy I know and his wife are a retired couple however their 2014 Corvette has about 8000 miles on it and it is at Bill Kay waiting to get a new engine ... What the heck ? Did you say you knew of owners who also had their engine blow ? This guy and his wife are carefull corvette lovers all the way never an ******* behind the wheel but they do have 2014 Vin number 41. Did Chevy overlook QC and QA while building the first early engines. Bill Kay has said nothing on this subject. They won't even say which component failed.

Thanks,
Kevin

Funny I have a co worker that lost his motor at around 8200mi

Sad. One of the reasons to avoid the first run of a new anything.

Mine is a 2014 with a vin # in the high 25,000 range.I hope GM got it fixed by then or early 2015 vin #'s would also be affected I would think just saying it is the same engine with no changes to the engine from 2014-2015.

GM sold over ~34k 2014 Corvettes. Some percentage of those are going to have issues. There has been a lot of talk about early engines having an issue with the way the springs were installed in the heads. I'm not surprised we have an unfortunate handful of broken LT1's.

Now on the C6 Z06, I have 2 friends that BOTH lost valves and blew their engines. Just coincidence probably but I seem to have read of a lot of Z06 engine issues.

Hopefully it is just a few isolated incidents. Hope that particular owner gets his car fixed soon.

I few 2013 427s blew over here as I recall as well. I wonder if its an oiling issue hence the new mobil-1 mandate.

Not to start another oil war but my personal experience is Mobil 1 5w-30 runs a bit thin. I had an 02 Z28 and I was using Mobil 1. It started sounding like a sewing machine and so I had the oil tested and the test came back that the oil was in bad shape and appeared overheated and some unexpected wear. They suggested a thicker weight oil. I never beat that car, in fact the exact opposite. I switched to the German Castrol 0W-30 after reading a lot about oils and the sewing machine sound went away and the next oil test at 5000k miles came back a lot better with high TBM telling me I could go 7500 before the next change. Been using that ever since. Too bad they won't pay for the Dexos 1 certification but I'm still using it.

I currently drive a 2011 Subaru WRX( waiting on my C7 to be built). Subaru switched from 2.0 to 2.5 liter engines in 2009 and the first few batches had blown engines! Crank shafts or bearings if I remember correctly.

So, I think a few broken C7 engines out of 34,000 isn't too bad!

Does not care that a few engines, of a very new design, break. Feces happens. If mine goes belly up, then the warranty fixes it. In the mean time, I will drive and enjoy the car and not let a "possible" distract me. Time is too short to let the little feces ***** bother you.

What makes me laugh is GM has blamed the C/D test car failure on a bad oil filter however no one from GM comments on cause of these other failures. It would be nice to know what the findings really are.

BIG Dave

This stuff has always happened throughout history. Nothing new. There's always been a small percentage of engine failures in every model, every brand of automobile ever produced. And it will continue to happen. Ask anyone that grew up working for an automobile dealership. The only difference is now there's the Internet so people can post this stuff, other people read it and next you know the sky is falling. And as far as first year issues, once year-two production starts, engine failures do not instantly drop to 0%.

PMD C6

A little birdy just told me that Bondurant has blown about 10 engines already. 2 just yesterday. I searched on here to see if anyone else has heard the same but I couldnt find anything.

nsxpilot

Chief instructor at Ron Fellows told me they have had ZERO engine failures on their C7's.....

Not to mention that the C7 has an extremely high performance engine that pushes the limits of technology (yes, even though it has push-rods) and manufacturing constraints. After a full model year of production, it looks like Chevy knocked one out of the ballpark as far as reliability goes.

You KNOW that C/D test car had the snot beat out of it. That's what they do. Heck - that's what any of us would do to someone else's car.

Not all first year cars are bad. I know many 2005 C6 owners such as myself that has NO problems with there corvette!!! NADDA

I read somewhere that they had found an assembly robot malfunctioning and dropping metal bits into a cylinder during assembly, and that they have fixed it now.
