Reading about all these Corvette engine failures is one thing, but actually hearing the knock is quite brutal. The video below doesn’t represent the first occurrence, yet GM hasn’t officially made any statements regarding the multiple engine failures.
We’re sure somebody’s noticed by now, as the sounds heard in the video below are hard to ignore.
There was an issue with getting a replacement engine for this Corvette that supports evidence that this defect could be bigger than we think. The first replacement engine that was sent to the dealership arrived with metal dust in the cylinder heads, and was sent back. If you recall the Stingray which was long-term tested by Car and Driver that suffered an engine failure at only 6000 miles, it too was affected by loose metal which got into the motor’s bearings.
We hope to hear something from GM in the near future, and that no other failures occur. Do you think Corvette fans should be worried, or are these just a few isolated incidences? If so, when does a few become too many? Watch the video, and then let us know your thoughts.

Aw man that’s terrible! Let’s hope GM can figure out what’s going on.
Them pushrod V8s is new technology. Allow GM another 60 years to iron out the bugs.
Yes. Because GM is the only car maker with an engine issue.
They also need to investigate the root cause of the recurring fuel pump module failures — that issue has received a lot of attention in recent Automobile Mag articles. These issues are becoming VERY visible to the public.
It’s sort of to be expected with engines that were recently redesigned from the ground up, that’s why I wouldn’t buy a first year redesigned model “”brand new” unless it has a few years in it.
This sound reminds me of the HEMI-tick that has plagued those mopar V8s for YEARS.
Are these engines being abused?
If the dealer gets the replacement engine and pulls the valve covers off to inspect the engine and finds metal shavings, something is wrong. That is not an abuse or a break-in problem. Something else is going on.
I wonder if the owners followed the engine break in period listed in the owners manual ?.
I have one of the first 2014 Z51’s VIN 1496. I have now got 21,744 miles on her. I take care of my cars and do not believe in “Garage Queen’s”. I think as with anything that is manufactured, eventually one will not be right. Two out of how many? Na, just bad luck with those.
It’s more than just two.
Worried?
Dissatisfied, and disappointed.
So disappointed you made me GM!
Maybe there is a saboteur at work, adding some metal shaving to destroy the engines. A serial killer of a different kind. Same kind of nut that sets fire to SUV’s on the dealer lot to save the planet. I know how clean the engine assembly room is. The only way those shavings got in there is someone added it after the engine was assembled. The sabotage has to be at the engine plant as the replacement engines that never make it to the Corvette assembly plant are affected too. Somebody needs to be stopped and stopped soon!
I’m glad they put the VIN in the video. That is a non Z51. Its got some miles on it for being a 2014. Makes me think it was tracked. If its a non-Z51, that means no dry sump oil pump. Tracking it would add extra stress on the motor, and if the oil pump is robbed of oil, things can fail. I’m not saying that’s what happened, as it wasn’t brought to my dealership, but I just did a quick lookup and saw the build.
As someone who went to the Corvette training, the first thing I ask people when they ask about Z51 is”Are you going to track it?” Plain and simple, people abuse performance cars. They want to hear the engine roar. That want to take off hard at stop lights. Anytime you make a machine, it has the chance of breaking. Look at any form of motorsports, there are engine failures. Even the best engine builders in the world have failures. NASCAR, F1, etc, Why people single out the Corvette is mind boggling to me. I wonder how many F150’s have blown motors this year. Or Challengers.
pls add me to the growing list of fuel pump failures. Oh G M here is one for you this was not on the track no sorry it was in the church parking lot . I paid 954.80 out of my pocket . Also paid for first oil change at 3200 miles 4500 miles dealer paid for it at 5400 car now has 6200 on it. I have all oil analysis reports on all 3 for the record. The truth is i have never smoked the tires. Thanks for your time. The car is a 2014 LT3 conv. Z51 .
