Why are Japanese cars more reliable? - Chad.R
I'm sure most of you may agree that, in general, cars made in Japan tend to be more reliable than cars made in the rest of the world.

Why is this?

Is it that the Japanese have higher manufacturing technology standards? ...better engineering? ...more stringent quality control? ...better component design? ........what?

Or, on the other hand is this just a "modern myth", perpetuated since the 70's, when you could argue that all of the above factors, were in indeed true?

Now, I know that there are going to be backroomers with very reliable non-jap cars (myself included), also very unreliable jap cars, who may not necessarily agree with this theory.

However, I'm really asking the question on a "Japanese Motor industry Vs The Rest of the World's Motor Industry" and not on case-by-case level.

"But the Fench and Italian makers are the world leaders in electrics and electronics."

And Fiat make very very unreliable badly put together cars.. and their styling!

And most Renaults' under bonnet wiring look like grandma's knitting after the cat has got into it...

Anyone want to buy an old Fiat Turbo Coupe 20V , Punto or other such classics? The good thing is they are cheap. The bad things are...

Now Citroen's XM is a masterpiece in modern electronics applied to cars:-)

The new Laguna is an electronics masterpiece.

Has anyone actually made it more than 10 miles without those stupid tyre pressure things cocking up ?

There is also a rumour that Renault have made the decision to remove the bulb from the engine warning light.

The Dci model has now captured the record for most unreliable car of the year so far !

In a previous existence I looked into 'benchmarking' where companies compare the efficency of their processes and came across this anecdote.
In the 1980s (I think it was the 80s) Mercedes were making cars with a good reliability record. This reliability was achieved by good design and engineering but also a very strict quality control system. Each car was inspected thoroughly as it came off the production line and any faults fixed. Most cars had faults. Mercedes wanted to know how the Japanese managed to make cars of equal or greater reliability but in much less time and hence much cheaper. One of the Japanese manufacturers (can't remember which) let the men from Mercedes have a look at how they did it in Japan. Mercedes were horrified to find out that, on average, Mercedes spent more time inspecting and correcting one of their cars than the Japs did in building one of theirs, and yet the Jap stuff was at least equal if not better.
The moral was that quality isn't something you bolt on afterwards but something endemic to the philosophy of the company and its workforce. The manufacturing process was designed so that mistakes were less likely, management took feedback from the humblest worker in order to improve things and there was something in the psyche of the japanese worker that made them better at assembling things.
Touching on that last point, I have heard that japanese cars assembled here have a lesser reliability record than japan-assembled cars. Is this true?

Nick,

I too have heard this about Japanese cars built here, the 5 dr Corolla or the "Swindon" Accord seem to have worse records than there Japan built counterparts.

hence, in my original post "...cars made in Japan tend to be more reliable.."

IMHO implementation of efficient and effective management processes across the organisation and investing in the long term is key. This rarely happens in EU / US - short termism and resistance to change (and knee jerk reaction to give shareholder value) being the order of the day.
Japan has a different culture though this may now be changing (globalisation) - also the Japanese worker is traditionally / culturally fully dedicated to the company which may or may not be worth the price.

Autocar magazine featured an article on this about a year ago.Japanese cars are more reliable for two reasons
1.The quality control standards of their suppliers (eg Hitachi)are much higher than European manufacturers using Bosch/Lucas etc. components.
2.Once the design of the car has been signed-off no modifications or upgrades are made even if the car goes on sale inferior to the competition in some respects.One example given in the article was the double glazing system fitted to the BMW 7 series and Mercedes S class, which required the side doors to be hastily re-engineered as the cars were due to enter production.This led to problems with door hinges,wind noise etc.

Not sure how this ties in with "Japanese" cars assembled in Europe using locally supplied components
Why are Japanese cars more reliable? - THe Growler
I also in a previous existence had a great deal of involvement with quality thinking and processes from a management as opposed to an engineering standpoint.

The essence to be taught and internalised was that quality is PART of the process, not an add-on at the end to see if things have been done right: rather the quality is designed in from the start. Unlike the often once prevalent Western style where it didn't matter too much if it ain't screwed on right, those guys down the line would pick it up and fix it. This is what the Japanese have always understood implicitly. It's why my 12 year old Toshiba VCR still works perfectly, my National aircons in the house never go wrong and the Hitachi fridge circa 1988 has never let me down.

We need to factor in Japanese (Indeed Korean as well increasingly) culture here. After WWII Japan lay in ruins. The herculean efforts to rebuild meant it had to produce things people would buy, in the face of formidable competition from Western manufacturers. Not just cars but airconditioners TV's, - Japan was miles ahead with things like cassette recorders and so on, fridges et al. That mean they had to be affordable and not go wrong, ergo quality. Somewhere in the middle of this fits Prof Deeming, an American who allegedly invented TQM (total Quality Management) and introduced it to the Japs.

During the 1960's Japan flooded SE Asia with cars and trucks, Toyota, Hino, Fuso, Mitsubishi etc. They were reliable in rugged conditions where servicing skils and resources were limited. In 1964 you could drive through Thailand, the Philippines or Cambodia and all you ever saw after ex-US Military Dodges and Reos, was vehicle after vehicle and motorcycle after motorcycle from Japan.

In Europe they were virtually unheard of and when Honda made its first foray into the UK in 1962 with m/cycles they were sneered at as "built of monkey-metal" and "made on a bowl of rice a day". Prejudice was rife from people who had themselves been or had relatives imprisoned in Asia by the Japanese (Burma Railroad) and so on. At that time I was working with one of UK's first Honda m/cycle dealership and recall the amazement of our mechanics at the quality of engineering and assembly when they took them down, compared with the positively agricultural AJS's and BSA's in the shop.

When the first shovel front Coronas appeared in London in 1966, we all laughed at the weird shape and said Pride and Clarke won't sell many of them. But when we looked, not only were they very well built (remember we were comparing with Cortinas, Cambridges and so on) but they had EVERYTHING -- heater, radio, all that stuff you had to pay extra for when you bought a British brand at a price that was attractive. But you still had to face the neighbours peering from behind their curtains of course if you bought one of those weird little cars.

The first Western market forays were really made in Australasia, where in the mid-60's you had Mazda's, Princes (forerunner to Datsun,later Nissan, and the redoubtable jeep-looking Toyota Landcruiser. The Aussies soon overcame their prejudices when they realised these were reliable value for money vehicles that would cover Australian distances and temperatures and road surfaces without fuss. Holden, Valiant and Ford, the big 3 started to feel the heat. In the North West where I spent 1969 the Landcruiser swept the board for reliability and ruggedness, pushing Landrover way out, and make no mistake, your vehicle reliability in some of those places could genuinely mean life or death to you.

What distinguished the early Nips were their unsophistication (not much to go wrong, easy to fix) willingness of the dealers to bend over backwards and make it right if there was a fault. Their early styling was abysmal: check the Datsun 16OJ, Mazda 929, Isuzu Bellett, Toyota Crown circa 1966-78, but by and by they caught up.

Japanese "face" was restored -- another fundamental linchpin of their culture and reason for getting things right, and Europe in the days of crappy merchandise and endless strikes by undisciplined workforces at Ford and BL producing unreliable cars vs. Japanese order and precision with respect for authority meant Europe presented open season for Honda, Toyota and friends and they couldn't lose (except maybe the dreaded deal HOnda did with BL for the early Prelude :-(. We used to laugh at those clips of Nissan workers all doing their callisthenics when they started up in Sunderland (I think it was) and singing company songs before work but ultimately the laugh was on us.

Quality never goes out of fashion. In Japan it's something which is in the heritage and is linked to deep social and cultural norms. It has been said quality discipline is easier to instil in that framework than in the more libertarian individualistic West. Hramony and consensus is also terribly important and I notice during my spells in Japan (In another industry) that nothing change-wise was implemented without the full commitment of all concerned. This seemed to mean that many potential problems were ironed out right at the outset because everyone went to the job with a clear of view of exactly what was required. But it did take longer, and you just compare a Japanese manager's workweek in terms of hours with a European's!
Quite simply they work a damn sight harder.

Whoops I must be over time here. Don't want to be Bogush'ed.

Got it exactly right, Growler. As one who has been involved with half-*rsed attempts to introduce a Quality ethos in the UK I couldn't agree more.

Wasn't there also an issue in the 60's and 70's where it was difficult to export to Japan and so their industry had a monopoly home market to build up a manufacturing base?

Also I believe that our motor industry was hamstrung for decades by the VED system which dictated long stroke, small bore to get in a low tax class. When that went out our manufacturers had too much invested in that type of design to change overnight.

I agree with your comments about hard work and quality, although developing countries will always have an initial edge in low labour costs.
Why are Japanese cars more reliable? - Maz
In a nation of more than 120m people there's going to be a whole host of factors, and I agree with many of the above.

I don't believe the monopoly argument though. A cursory glance around France will tell you their car manufacturers have a virtual monopoly there, yet are at the other end of the reliability spectrum.

See also Trabants in Eastern Europe.

One that hasn't specifically been mentioned yet is the cultural effect of Nagasaki and Hiroshima. In recent Japanese history, the God-like power of science is there for all to see.

"A cursory glance around France will tell you their car manufacturers have a virtual monopoly there"

IMHO that is because the French are just about the most xenophobic race on Earth and support French industry and interests at any cost.

H.J. is absolutely right, - I had a friend who worked for a British machine tool company, who wanted to break into the Jap market and sent over some metal drill bits as samples for evaluation. They were duly returned with a hole drilled clean through the centre. I think this sums up the whole ethos of Japanese engineering!!

Why are Japanese cars so reliable? Because they have a 'get it right first time' attitude.

Someone further up(down) suggested Japanese cars built in the UK were less reliable.

I believe both Nissan and Toyota UK built cars are in fact said to be MORE reliable than their Japanese built counterparts.

its always intersting to look at how the same car made in different countries fares

for instance in my experience a german built vectra is better than a uk built one (yes i know theyve stopped making them in uk)

and i wish you could get easy access to stats which showed the true differences, although i believe that GM used to bring in almost complete cars and stick a few finals parts on it in the uk and log it as UK built (dodgy tax reasons probably) so the VIN plate isnt the full story

and also japanese corollas seem to get less problems than their UK built cousins

Such similar cars having such different track records according to where they are built must mean something ?

Why are Japanese cars more reliable? - Peter
A colleague of mine works in a world famous car factory on the outskirts of Swindon. He says their greatest problem is the quality of supplied parts. On the CRV he reckons he has spent many hours replacing fuel pumps for an internal fault. It is an intermittent fault and does not affect all cars, he says the pumps are made in France. He claims the Japanes parts always perform well but European parts tend to have the greater failure rate and that is before they leave the factory.

This reminds me of the old Granada saga. Everyone wanted a German built Granada not a UK built one. Ford dealers would NEVER agree to this arguing that they were all the same but they weren't. The German ones were better and the BG fleet manager used to check the vin plates and reject UK made one.

If you have ever been to Japan you must have noticed the intense attention to detail paid to even the tiniest item. The smallest thing seems to have importance and is given it. The mundanest item is decoratively presented or arranged, an item you or I wouldn't give a second thought to, yet someone has thought it important enough to merit consideration. On top of that is the formality with which customary processes like serving food or greeting someone is carried out. Translate that to the automobile and why is it surprising?

It's all there in the culture. Maybe not for you and me with our upbringing but it sure results in some good cars.

But the Japanese can be naughty......recently here in the Land of Sun and Fun emissions testing has been introduced and your vehicle is now tested when you take it to the traffic office registration each year. The highest rate of failures in relatively new vehicles is with Mitsubishi's, that's Pajero's, Pickups, the L200 series and so on. The motoring press took a look at this and discoverd that all Mitsubishi diesel engines imported here for assembly (vehicles are a mix of local assembly and imported parts) are a 1970's design which is dirty and inefficient and must have paid for itself over and over again R & D wise, but would not pass muster in a more developed market.

I doubt we shall see mass hara-kiri at Mitsubishi Philippines Corporation but it must have dented that company's spoutings about their role in environmental blah blah.

Having said that, the damn things still don't go wrong!

The local Far-East boys have it right - big smiles, excellent service, boring, bland but reliable products...

Requirement: automatic gearbox.
VW - we'll get back to you with a price/delivery. No follow up, ever. (0/10)
Opel - Auto's only start at Omega level here. Too big, sorry. (2/10)
Ford - don't return initial call.
Renault - ditto
Pug - no small autos available
Toyota - Take a corrola to the house, let mum potter about in it for an hour. She doesn't like it. (some feminine whim -she can't say WHY she doesn't like it, she just doesn't...) No problem, says salesman. Thank you for considering Toyota. (10/10)
Daihatsu - Same as Toyota, BUT took her out to potter about, left car with her overnight, came back next day, yes, she's happy. Took specs, left with car, phoned back - yes, there is a car to your requirements available, when may we delivery it?
Arrives two days later, with full tank, bunch of flowers,etc. Sales fellow shows her all over the thing, what lever does what, how the filler caps work,what each switch does, how to check oil/water etc.
Phone back a week later - is all well with the car?
Phone back 6 months later - have you forgotten your free first service? (No, she hasn't logged up enough miles for it yet!)
Send round bloke, take car away, back later in the day, service book stamped, washed/ valeted etc. 10/10.

Yes, the attention to deatil is almost obsessive.

A few years ago now, the Romney Hythe and Dymchurch railway loaned a couple of locos to Japan for a garden festival and one of their drivers went out there to shw them the ropes. Lighting up the boiler in the morning required some sticks of wood an oily rag and some coal. Not rocket science!

"How long should the wood be?"
"No longer than 30 cm"
"No, exactly how long should they be"
"Okay then 30 cm"
So all the firewood was cut to exactly 30cm. Perfectly good kindling 29.75 cm long or less was discarded!

I have done some work with a large international Japanese Component Manufacturer and have visited their UK operation.

Whilst touring the various sections as part of the consultancy project I noticed that in the inbound goods sections some boxes of supplies were opened, checked and counted and some not. When I asked how they determined which one and how many to open I found out that

a) only supplies from non Japanese manufacturers were opened and checked

b) Japanese produced supplies went straight to the production lines

The reason for this was explained to me as being experience showed only non jap supplies produced problems with quality or quantity.

The paintwork quality on my Sunderland built Micra is poorer than that of a typical similar aged Jap built Nissan, (e.g. Almera), and I'll go as far to say I've seen much better paintwork on some earlier version (K10) Micra's (Jap built) which are 5 years older than mine.

Otherwise very satisfied, I have to say.

But I intend to go for a 'proper' Jap built Nissan (Almera) next time around.

The Japanese factory looks at the order and breaks 0.05 % of the stuff coming off the end of their production line to meet the UK requirement, ie they were 100 % ok before that...

I would hazard there is also the traditional Japanese xenophobia at work here as well. It is important that the perception of Western inferiority/Japanese superiority is maintained at any and all costs. The complex culture dictates latter must be reinforced at all times. Face would be lost if Japanese products were thus checked, since it would imply they were no better.

This is a hard one to explain if you haven't worked there. Every single thing is about the giving of, or ensuring no loss of, face.

I recall an instance of an Asia-wide IT investment roll-out planned and managed from my company's base in Hong Kong. The hardware platform envisaged was a household Western name and the programme was in part designed to harmonize across a geographical area a motley array which had grown like Topsy over the years. Much development and testing time and money was involved to demonstrate the set up worked and met the business needs under all conditions. The Japanese simply would not accept the foreign hardware and moved heaven and earth with enormously creative subterfuge, not to mention dirty tricks, to avoid taking onboard the rollout plan for their country. They had to have a Japanese hardware provider at any cost.

In the end politics, face and pragmatism converged and they got what they wanted, for once, with a less superior Japanese product. It all simply came down to the "disgrace" which would have befallen the local management had they accepted a foreign hardware supplier, by implication admitting their country could not produce the best there was.

Sorry off motoring slightly, but the dynamics behind why Japanese stuff is the way it is a study in itself!

But they do make some blunders: after WWII they designed the rebuild of Tokyo street configuration based on that of Manila, which their army had just recently occupied! That's given them a traffic problem like ours.

Many of the comments above are correct as far as I am concerned, but no one has yet mentioned the words "Toyota Manufacturing System" There is a series of books published by Productivity Press in Oregon that cover the way Toyota managed to do what they do to improve reliability in the cars they make. I think basically it grew over many years from the ideas of one man, Shingeo Shingo, who looked at how Toyota produced cars and basically said lets do it right in all respects first time and reduce the time to make it. The family has just got back from the fireworks so have to go.

Why are Japanese cars more reliable? - acrabat
Reliability all comes down to basic engineering and the philosophy of the people who run the motor company.
I remember speaking to this chap in the early eighties who worked in the leyland/rover factory. He described to me how cars were coming of the production line with hugh whopping great faults. Being a conciencious sort of bloke he went to his line manager to tell him. His manager told him not to worry that whoever bought the car could get it fixed at a dealership.
There is the difference, the eastern manufacturers top brass actually cared whether their cars were reliable. The British bosses couldnt give a stuff about the consumer.
Of course I do believe things have changed since then, but then again mabey it hasnt.
