Why Toyota engines are so reliable (and cars).
The disposability of consumer goods in the modern world has long been a byword. Today, no one is surprised that kettles can only work for three months, and a washing machine can only serve a warranty period. Manufacturers of goods around the world have taken as a basis the philosophy of rapid obsolescence of goods by reducing the quality of products. And the worst thing is that this trend has affected not only simple goods but also electronics and even cars. True, the latter has become less reliable due to the growing complexity of the technology. Although discounting production costs in order to maximize profits is also not worth discounting.
At the moment, there are not many car brands left in the world that adhere to the classic philosophy of producing reliable and high-quality cars. One of them is the well-known Toyota, which is famous for its strong, durable cars.
We at lovecarbatter.com love to collect the opinions of people and specialists who talk about the benefits of goods, cars, and much more. So today we decided to introduce you to the reviews of people who told Quora.com (a foreign analog of the Yandex Q service) about why Toyota engines and cars are among the most reliable in the world .
- In 1947, an American named Edwards Deming arrived in Japan. The purpose of his visit was to teach the Japanese about quality control through statistics. History proves that Toyota paid great attention to his ideas and learned a lot. The Japanese believe in continuous improvement and rigorously test their products, do not introduce advanced technologies until they are proven, and find it extremely important to listen to customers. Deming’s photograph still hangs at the company’s headquarters.
Honda was once laughed at – in particular, the British after the first race on the Isle of Man. But she returned with better cars the following year and beyond. Everyone was not laughing when she began to take most of the highest awards. Then its products killed the British motorcycle industry and nearly bankrupted the auto industry.
Toyotas have not always been reliable either. In the 60s, they were vulnerable to rust and looked very disadvantageous against Chevy and Fords. It took them decades to earn a good reputation. It was a big mistake to underestimate the Asians. — Tony Lam / Quora
How is the Toyota production cycle different?
- This company has one of the best quality control systems in automotive design and manufacturing. Nissan is about the same level. Most of the leading competitors also operate at a fairly high level, including American, German, British, and French automotive corporations. But they are often thwarted by old product design methods and build quality.
Toyota lines work without defects. Not a single bad part ends up on the conveyor. Suppliers adhere to the goal of “zero scraps”.
For example, during assembly, a worker tightens bolts using an automated machine that simultaneously tightens all parts using torque and controls the tension force. At the end of the assembly line, an inspector checks each bolt to make sure everything is working properly. Then each connection is checked again by a senior inspector. If an employee ever makes a mistake, they are immediately removed from the assembly line and sent back to training or assigned to another job. Toyota employees are rarely fired; they have retrained over and over again until they are perfect. Some of the most experienced can (and do) work anywhere on the conveyor because they know every detail of the chain – right down to the final inspection. — Thomas Warmot / Quora
Are Toyotas really the most reliable cars in the world?
- Usually, it is. While the average modern car travels 200,000 miles without significant damage, a Toyota can easily cover 300,000-400,000 miles or more. For those who are accustomed to operating in kilometers, this means that many Toyotas easily overcome 500-700 thousand km, and often over a million.
Many people confirm this. Including experts and owners of cars belonging to different eras of the automotive industry. Of course, there are also bad samples, but in the bulk of Toyota, they really have amazing durability. Even with constant abuse and lack of careful maintenance, 180,000 miles (300,000 km) of trouble-free driving is the norm.
Note that neither Toyota nor its luxury division, Lexus, aims to break performance records – instead, they focus on reliability. They can easily build a top-notch, high-performance supercar if they want to, but they know full well that the more performance-oriented a car is, the more difficult it is to maintain reliability.
Does this mean that Toyotas last a long time? Usually yes. But other cars can last almost as long with prudent use and proper maintenance. Statistically, Toyotas can handle tougher challenges than the average BMW and still last the same amount. Hence, they are more reliable. Do it with a BMW and you’ll end up with costly engine repairs or possibly turbo problems.
In addition, Toyota units are easier to remake and subsequently more easily tolerate major modifications even without proper maintenance. Toyota knows how to reduce stress on parts to make everything more reliable. The Germans can do it too, but they have a different focus – either performance or luxury, or a bit of both. Therefore, it is hardly reasonable to assume that, for example, Toyota is better than Merce / BMW or vice versa. They just serve different purposes, and that’s the main thing. Now every car brand strives to improve quality, but they all do it at different levels. — Romano Miller / Quora
- If we talk about the minimum number of early failures, Toyota is not at the top. The bounce rate is something like this:
1) Honda – 1 out of 344;
2) Toyota – 1 out of 171;
3) Mercedes-Benz – 1 out of 119;
4) Volvo – 1 out of 111;
5) Jaguar – 1 out of 103.
At the bottom of the list is MG Rover with 1 out of 13, Audi with 1 out of 27, and MINI with Saab with 1 out of 40.
In terms of top mileage engines, Toyota isn’t in the top ten, and neither is Honda. Now we are talking about vehicles with a mileage of more than 1.5 million kilometers, with a maximum mileage of up to 5 million kilometers. Here, Volvo with the original engine (and manual transmission) and Mercedes are in the lead. — Robin Wells/Quora
- Even if you consider that these are not averages, but simply record holders, they give a good idea of \u200b\u200bhow well their engines are designed. Toyota also has excellent engines – in the secondary market, you can often find copies with a range of half a million kilometers, which are in excellent condition. The fact that a particular unit looks bad does not always mean poor design or sloppy assembly. This can happen when, for example, a vehicle designed for operation in cold countries is used in a hot desert. Then it’s not the cars or the engines that are to blame, but the poor choice. — Carmel Poulet / Quora
Let’s not get carried away by stereotypes – there is nothing magical about Toyota / Lexus cars. But they do have a really high mean time between failures. And many other “Japanese” (Mitsubishi, Mazda, and Nissan) have very high-quality cars. The reason lies in the traditions and industrial standards of production, in compliance with the obligations of suppliers, work ethics, and strict quality control.
It has been observed that countries with strong labor unions generally produce cars of mediocre standards. The US, UK, and Italy are examples of this. Germany is no exception. German-made cars were once famous for the highest quality – unfortunately, over the past decade, the situation has changed somewhat. VW and Audi are no longer considered reliable cars, nor are BMWs, and try to find a Mercedes that doesn’t break down in the first 5 years. In fact, in the West, too much money is spent on paying a labor force that is not interested in devoting itself to work. — Morten Christoffersen / Quora
- In Japan and Korea, the opposite is true. Manufacturers traditionally make demands on suppliers of parts, materials, equipment, etc. the requirements are very high, the workforce is deeply involved in the assembly process and takes pride in its excellence, and the control is very strict.
It all boils down to this: cars are made from high-quality components, assembled by staff who take pride in their work, and any substandard products are rejected. The Japanese have a different culture than in countries where making a profit is the No. 1 goal. — Morten Christoffersen / Quora
- Recently, however, Toyota has begun to slip through “jambs” – on the Internet, for example, there have been complaints about cars with a cracked engine block. Block cooling problems due to uneven coolant circulation or fuel pump failure (particularly 2018-2020 Corolla) are the most common, but there are others. Google the phrase “the whole truth about new Toyotas.”
But it’s not the shortcomings or oversights themselves. When Toyota makes a mistake, it doesn’t challenge it, it looks for ways to fix it. The same goes for engines. Other manufacturers throw away the failed sample and build a new ones. The Japanese, on the other hand, have a culture of constantly improving production processes and finding errors. Car owners are even rewarded for finding omissions. When they “slipped”, production stops until the defects are corrected, and the company itself focuses on customer satisfaction. — Dingane Nhaule / Quora
- For any Japanese, reputation is everything, and therefore Toyota tries to do business in such a way that cars last longer, parts are available everywhere and there are enough service specialists. In addition, the company spends a lot of money on user opinion research and develops in accordance with it. This is its advantage, because many other automakers, instead of implementing what the consumer needs, are promoting innovations that people do not need.
Toyota’s progress is best described as “gradually and steadily.” This is the Toyota mantra on the way to the durability and reliability of machines, systems, and engines. Slow and continuous improvement has played a decisive role in their popularity. Long-term planning and focused strategy, open-mindedness and humility, deep concern for customer satisfaction, research and development aimed at providing optimal functionality, diligent speed, and obsession with quality have become the connecting success factors. — L.S. Ganapati / Quora
- I would not single out Toyota engines as generally more reliable. With proper care and maintenance, most “conventional”, mass-produced modern non-turbocharged (also called naturally aspirated) engines will go up to 200,000 km, if not 300,000+, with minimal operating costs. But a car engine is more than just an engine.
To their credit, today Toyota still uses naturally aspirated engines, while most other manufacturers use turbos to reduce displacement and increase economy without sacrificing too much power.
Metallurgy, machining, and oils have always been important factors in the durability of classic engines, but this is not entirely true for modern automotive turbo engines.
A typical car engine runs between five and ten thousand revolutions per minute. The turbo booster produces extra power by forcing extra air into the intake port. This is achieved because the hot exhaust gases sometimes spin the turbine at over 100,000 rpm. Current mass-produced turbocharged engines will almost certainly get through the end of the car’s factory warranty, well, maybe another 200,000-300,000 miles on top of that, but hardly more. Ordinary motors, not only Toyotas, have a longer resources. — Andrey Abutin / Quora
- According to Consumer Reports’ annual reliability rankings, Toyota ranks second in the world with a reliability score of 78 out of 100. Many Toyota owners believe that buying a Toyota vehicle offers several benefits. Here we look at the reasons why Toyota is so reliable. Toyota takes a conservative approach when updating its models. The company does not believe in the introduction of advanced technologies to attract attention and increase sales. Instead, she studies classic trends and looks for ways to improve useful features that add value to the car.
Today you see that car companies place more value on looks than on features. For Toyota, the purpose is more important than form. For example, you won’t see a Toyota car with maximum torque, power, or speed. Toyota vehicles stand out for their understated elegance. A large number of buyers like Toyota vehicles because they offer excellent comfort, drive well, and rarely break down.
Why Toyota lasts longer:
One of the reasons is that they build their motors with low load levels. You also need to consider the total cost of car ownership, which goes down the longer you keep your car. Toyota has some of the most durable cars on the market. The ability of Toyota vehicles to stand the test of time has earned them a reputation for reliability. Since Toyota cars rarely break down, you will spend less on a car while you own it. — Rehman Chaukhdry / Quora
- Toyota is a manufacturing and technology company specializing in the production of automobiles. They could produce anything, but they chose cars.
The company is essentially run by engineers, not accountants. Their whole philosophy is based on looking for ways to improve everything that is possible. At each iteration, things get better, and then another way to improve is found. They constantly strive to reduce the complexity of production. For example, reduce the number of parts. They design universal parts and assemblies that are transferred to different models. Also, they never cheapen parts to save money. Their concept: spend money to make a part cheaper to manufacture by streamlining manufacturing processes.
This is a company that carefully monitors the reliability of its products, and every employee shares this philosophy. Everything that prevents the production of the best product at the lowest cost is removed from the production chain (or modernized). Why make a 50-piece subassembly when you can do it for less with a better design or new, more efficient tools. Invest in equipment and workers to make it easier to make a better product. Here is the secret to the success of their cars. — Pete Lacey / Quora
- Toyota is a “genius at the core.” Their engines are simple, well built, and made from quality materials. And when they find the perfect formula that works, they try to use it for as long as possible without trying to improve it. For example, if it concerns any successful reliable part or component, then they will try to use it as much as possible. So, Toyota has been using the current 3.5-liter V6 engine in production almost unchanged since 2002. This is a long engine production time (by modern standards), and during this time only minor changes were made to it.
They are careful not to use small engines in their large cars, so as not to reduce the resource of power units, and they do not reduce the quality of engine assembly. And they are conservative about changing anything; if they are not 100% sure, the release of parts and auto components will usually take a very long time. They use their 3.5-liter V6 engine in many vehicles ranging from the Lexus 350 to the Tacoma, Avalon, and Camry. I have a friend who owns a 3.5-liter Toyota Avalon that has already driven half a million miles. What is even more surprising is that he does not really follow the car. Some motors are simply designed so well that they can last a long time even if maintenance is neglected. And the most important thing. Toyota made sure all of its engines were like this. — Nick Musial / Quora
- Previously, Toyota cars were cheap and technologically simple, not at all complicated, like Honda. Unfortunately, cheap and simple cars are no longer needed by people today. Consumers these days are looking for high-tech, electronically-packed cars, of which there are more and more in the car market. Therefore, today Toyota is experiencing more problems, unlike other car brands that use a lot of electronics in their new cars.
Toyota has its own service departments, its own maintenance philosophy, and its own code of reliable cars. But do not forget that Toyotas are mass-produced and this is NOT hand-built.
Their material quality is below average. Look at Toyota Tundra frames that rust quickly. I see how many cars of this brand come to us with frame corrosion problems. Also, a lot of cars have problems with oil consumption and with cylinder heads. So I do not think that today the cars of this brand are any special. — Michael J. Maniscalco / Quora.
Toyota organized its production a little differently than other global brands. The main difference is the production method of Jidoka. Jidoka is a process at Toyota where if there is any deviation or something out of place on the production line, anyone can stop the assembly line so that the problem is solved as soon as possible.
Another thing that sets Toyota apart is its just-in-time practice. This means that Toyota does “what is needed, how much and when it is needed.” They don’t complicate their models. If you notice, many Toyotas use the same parts (a practice called Just-in-time). If you’re interested in learning more, Toyota explains it all on their website, so I recommend you check out their page. — Tristan Barnes / Quora.
