Hyundai Whistle-Blower, in Rarity for South Korea, Prompts Recall

This is a fundamental engine design issue in their popular Theta II engine that results in premature and excessive wear on cylinder wall, leading to excessive noise, vibration, stalling, and ceased operation.
In a quest to save weight and increase power, they made connecting rod too thin and height of the bearings too narrow to hold unwanted movement of pistons in check. Instead of piston moving just up and down, there was sideway play often resulting in severely scratched cylinder wall after 15k mile of driving. There are many reports of connecting rods grenading altogether.
For those not familiar with engine parts, here it is. https://image.slidesharecdn.com/sixstrokeengineppt-140826102...
Hyundai found out about this pretty quickly, and de-tuned engine output in later iterations to increase reliability. Yet, they have consistently denied this design defect as a problem for many years.
There already has been multiple massive class action lawsuits and recalls on this in the U.s. since 2015. Many Korean customers were angry that Hyundai was not issuing the same recall in their home country, where they often pay higher price than identical exports.

The only fix that will 'stick' is complete engine replacement.
I hope Korean customers get the same treatment.
Coincidentally, I was recently reading about early American cars and their heavily overbuilt construction is a huge contrast to this "value engineering" of modern engines; whereas those old engines could be tuned to make far more than stock power with little effect on reliability, it seems today the aim is to make the margin as narrow as possible --- just enough to get past the warranty period, with the associated effect that, due to how the statistics work, quite a few of them will fail before too. Samsung's "exploding" washing machines are a recent, non-automotive, example of this.
Today's cars may be more efficient and less polluting, but if they last a fraction of the time as the old ones and have to be replaced many times more often, are they really that much better environmentally overall?
This chart is enough to make you cry: https://en.wikipedia.org/wiki/Cadillac_V8_engine#500
Anyway, eventually engineers learned how to make engines that are highly efficient and have very low emissions, basically by making the things as complicated as sin.
For a good 10 years or so, all of these goodies they added (like Mass Airflow Sensors, etc) would fail in mysterious ways, and be very expensive to replace.
Now most of that stuff is pretty solid too.
A lot of opinion about car tech is set by stuff that is 10-20 years old, which is both fair and not fair. It's fair, because it's hard to tell how things will wear when they are new. It's not fair, because engineers have already fixed a lot of things that went wrong in the previous generation.
Anyway, Cadillac now has a 3.0L Turbo [0] that makes as much hp as the 8.2 from above.
0. https://en.wikipedia.org/wiki/GM_High_Feature_engine#LGW
Disclaimer, I work for GM, but I'm on on any engine team.
after several rounds of detuning for smog controls, among other reasons.
I doubt any of those "other reasons" were because the engine couldn't survive 400hp.
in the same wiki link you can find this for 1971.
365 brake horsepower (272 kW), or 235 horsepower (175 kW) in the new SAE net ratings
The biggest engine ever in a production vehicle, until the second-gen Viper came around.
Modern cars as a rule go hundreds of thousands of miles without major problems while using a fraction of the gasoline per mile and producing a fraction of the pollution.
Yeah, sometimes they get it wrong and design something that doesn't last. But do you think that didn't happen before, too? Remember that the models we know and remember 50 years later are the winners. There's a strong survivorship bias at work here.

I wonder if it's hard for younger HN readers to appreciate the progress here? Having a car last 200,000 miles used to be a stroke of insane luck, like living to 90 years old - for most car models in the last 10 years, 200,000 is basically the least you could expect to get out of a car.
They had a million mile tundra not long ago, I don't think you'll find a million mile engine from the 50s-70s
How many typical new cars would it take to get to that? How many typical old cars?
The transmissions are another beast. They just seem to die at 140k, plus, or minus how you drive.
Their wasen't constant valve adjustments, or carb adjustments , distributors were dead simple. 90% of the time it was a bad condenser, or the points contacts needed sanding, unless you happened to own a British Vehicle.
And yes Amercan vechicles made in the late 70's, and 80's were aweful.
Old was not necessarily better, but Shade Tree mechanics could work on them.
There's a reason wealthy men buy old classic cars. A few years ago the average guy could buy a vice classic. Today--it's changed. Their are guys stockpiling older collectable vechicle.
Every wonder why the new cars offer just 7 year, or 100,000 miles of the Powertrain warranty?
Conversely, this doesn't mean that cars were made poorly in the past, it's just that the technologies and methods used in their manufacture have improved over time.
25 years ago is 1992, this is already way into "modern car" territory and million-kilometer executive cars.
Nowadays that's the minimum we expect (even for bargain-basement Korean subcompacts,* exotic Porsche sports cars or bleeding-edge high-technology computer-controlled Teslas), but >25 years ago it was virtually unheard of outside the Japanese brands.
*The Hyundai Excel and Pony had such poor reputations for reliability that their brand image still remains somewhat tarnished in the US, while the Daewoo brand had to be retired in North America/Europe entirely (I believe some of their models are now sold as Chevys).
Specification: Engine design lifetime = 2000 running hours.
CAD and FEA are great, but the above spec ruins it. You get parts made of light alloys and plastic, made of the minimum amount of material possible. They happen to be mostly fine when everything is perfect but any unintended load or crack in the plastic due to aging results in a catastrophe.
It seems odd that you would accept a design lifetime that is 40% of a car made 13 years ago.
I'm also not clear why you would expect the majority to perform above spec? Wouldn't a significant number fail under spec? Isn't a care which may become a total loss in 60-80k miles basically tissue paper quality?
Personally, I think a pretty big swath of engines make it well past 100,000 miles now - there are usually other issues with cars at about the 10 to 15 year mark with most makes and models that have to do with rust.
Designing engines that last significantly longer on average (say 250,000 miles) would require either a beefier design, which will add weight and reduce efficiency, or exotic materials that will significantly increase the cost.
Automobiles are pretty amazing for what they are. I agree with many others that they have gotten ridiculously complex, but this is mostly because of the emissions requirements - and that said I do enjoy the fact that smog is not much of an issue (at least in the US) these days.
Most used cars I've looked at in dealerships (as opposed to the Craigslist/Uncle Henry's as-is-where-is private sales) were overwhelmingly former lease vehicles.
It replaced a car that had 190k miles from around 2000. Its worst problems were a bad A/C compressor (replaced at ~100k miles) and a slipping clutch (it was the original clutch). The plugs and wires were replaced once during its service.
Modern cars are amazingly reliable and amazingly safe compared to their predecessors.
In those days you were lucky to get 80k miles on an engine before it needed a rebuild, while it's not hard to find post-2000 cars with over 250k miles on the original, un-rebuilt engine.
Should my car buying decision take into factor the fact that SKorea, as Nytimes says, punishes whistle blowers?
If so, does this happen in Japan too?
How does one take this kind of stuff into account?
If I may rephrase your question to "Should your car buying decision take into factor the fact that SKorea does not have as strong whistle blower protection as the U.S.?"
Car market in the U.S. is so competitive, and consumer protection so strong, that personally it wouldn't influence my car buying decision in the U.S.
If I were buying a Hyundai in Korea, then yes, it would be a factor, though how much, it's hard to say. I don't believe Hyundai would consistently misbehave like this. It's entirely possible that had the fix been cheaper for this engine recall, Hyundai may not have dragged their feet.
As to your question on Japan, I'm not really qualified to speak about whistleblower protection legal frameworks about either country. Both countries have it, but they are relatively recent concept, where there still is strong sense of company loyalty, hierarchical chain of command, saving face, and slim chance of re-employment in the same industry after whistleblowing event. It probably still needs to time to mature.
Either way, if I were buying Korean or Japanese goods in the U.S., all I would care about is product quality and performance. They are both nations of people that take strong pride (some may say too much) in their outputs, and care too much about how their countries are perceived on oversea stage that to have meaningful impact on their product quality.
So, whistle blowers get a "vacation" for the rest of their careers. Hard to say if that's better or worse than getting fired.
PS: How does one follow replies on this website? I'm new here.
Are you asking this as a moral question or a technical/value question? For moral, I can't help you. For technical/value, new Hyundais/Kias are generally regarded as very decent cars.
>If so, does this happen in Japan too?
Japan also has a VERY hierarchical management system, where top-down direction is the only way things are done.
> How does one take this kind of stuff into account?
One generally does not, because generally speaking none of these things have a first order effect on the product.
Many people with well over 100k don't have any issues, so it's bit of a crapshoot.
Given the cost of this recall, I don't think they're stupid enough to keep cranking out the same engine without having high level of confidence that the issue has been more or less addressed.
With that said, even in its revised state, I doubt this engine will be as reliable as Toyota's AR engine or Honda's K24 engine. Time will tell.
Even if the courts required a company to restore my employment, I would find it impossible to walk into the office of the company that I had whistleblew.
Engineers speaking out about safety issues that then get swept under the carpet must be amongst the most frustrated people in the world. First you go to school for many years to learn how to do the very best job you can and then some pencil pusher annuls all that by refusing your input because it affects the bottom line in a negative way.
Kudos to this man, I'd hire him in a heartbeat if I was in a position to do so. He's even more courageous than it might seem at first glance because in the society he's from this is an absolute taboo to the point where airplanes have crashed because people did not dare to disagree with someone senior in rank.
He's close to retirement age anyway, so by resigning voluntarily instead of being terminated for cause, he gets to keep his pension and other benefits. (South Korea has a public pension system, but large corporations often add a lot on top of that.) Hyundai also agreed to drop all other complaints against him in exchange for his resignation, which would not have happened had the court just ordered them to pay him a bunch of money. This man deserves a peaceful retirement.
I hope he moves to another town and runs an auto shop or something :)
Or similar?
Just interested to see if anyone could elaborate or dispel this notion for me.
I guess it comes down to the character of the person?
Not always:
"Whistleblower awarded $1m in $40m Princess pollution case"
http://www.seatrade-cruise.com/news/news-headlines/whistlebl...
That's a pretty high price to pay for just doing your bloody job and society should make sure they get rewarded properly for providing some necessary transparency and safety.
Given all that what should really surprise you is how much integrity these people have, they know that they'll be dealt with unjustly, that their lives and the lives of their dependents will probably be ruined and still they blow that whistle, loud and clear.
We need more of these people, and fewer 'team players'.
Some blunder forth into hell unimaginable, and others create a springloaded safety net before cutting away. It's often difficult to distinguish between the two, since whistle blowing often captures spectacular attention, and even the flame-outs that jump out of the frying pan and into the fire seem inspirational in that sense of a tragic, yet dashing pyrrhic victory.
But seriously, any given whistle blower should consciously attempt to organize a launch pad and a landing zone, even if for a crash landing. For every poorly understood tragedy, we usually get another negative example of "why no one should do such a thing," rather than "what went wrong and how to do it right."
I absolutely agree with you, but there's a bit of a nitpick to be made here--but an important one:
From Google: "A whistleblower (also written as whistle-blower or whistle blower) is a person who exposes any kind of information or activity that is deemed illegal, unethical, or not correct within an organization that is either private or public."
Whistleblowers by definition do not need vindication.
Vindication: "proof that someone or something is right, reasonable, or justified."
A whistleblower is not a whistleblower unless they reveal wrongdoing.
Edit: For example: Snowden is by definition a whistleblower because the information he leaked revealed illegal and unconstitutional activity. The courts already ruled it illegal. So he is by definition already a whistleblower/vindicated of wrongdoing. Perhaps the OP intended (and rightfully so) some statement about public opinion/perception of the value of whistleblowers.
By contrast: someone who leaks information containing no wrongdoing or nothing illegal is not a whistleblower. In other words: perhaps in such cases some extenuating circumstances may mitigate or vindicate the offender of wrongdoing. Whistleblowers, however, are not in such situations.
It's a weird Catch-22. You don't sue for your job back, you don't work there again. You do sue for your job back, you won't want to work there again.
Best thing in the case of wrongful termination would be to sue for enough money you can spend a year or two not working after your lawyer and the IRS take their cut and then take your sweet time looking for another job.
> On Tuesday, the two sides appeared to reach a deal, with Mr. Kim resigning from Hyundai and the company withdrawing both the lawsuits and the complaint to the police, a Hyundai spokeswoman said.
If the court had ordered Hyundai to pay him a certain amount of money for wrongful termination, Hyundai would have paid him and then continued with the lawsuit to make him pay back even more. They would have dragged on the lawsuit for years to ruin his life.
Instead, the court ordered them to continue to employ him until such time as he chose to resign. Which gave him a lot of power to dictate the terms of his resignation. He's close to retirement age anyway (most employees of large corporations in Korea retire between 55 and 60) so in addition to dropping the lawsuit, keeping his pension and other benefits would have been a high priority for him.
On the other hand, it takes a great deal of courage and determination for a man to make actual use of such leverage against his employer. Kudos to Mr. Kim for standing firm and asserting his rights not only in his act of whistleblowing but throughout the aftermath!
Apparently the OP isn't the first to use it and it's kind of a predictable back-formation.
Hmm. That's pretty general, but he may be right. The engineers willing to lie tend to get promoted to management to do the necessary lying on behalf of the engineers that aren't.
It almost appears as if the brain almost doesn't allow us to see what we need to see, and think what we need to think to be good at those task, if doing so will interfere with our self image and/or worldview in a similar vein as our more physical self-preservation instincts make it very hard to consciously do things that will cause pain or harm.
I don't think it is about having to be altogether rational or truthful, but rather that you and the perception of whatever world you experience will not be significantly challenged by the observations you do each day, the thoughts you experience, and the decisions you make.
> Truth be told, the incessant lying by this president and the elaborate apparatus he has built in the White House to bend reality to meet those lies means that nothing they say is to be believed anyway, but this is of a different nature. This says to America: I’m going to tell you a lie that is so outrageous that you will want to believe that some part of it is true, to preserve your faith in truth, democracy and mankind.

No one wants to believe they made a bad decision because like you said, they want to be doers of good.
And it's not a sign of a good engineer at all.
Is this really the Korean mentality? It makes me wary of buying anything from that country if it is, let alone something expensive and potentially dangerous like a car.

That article about GM says nothing about how the US public thinks about whistleblowing, does it? Could be wrong but I think they generally respect it.
Kudos to Kim Gwang-ho.
