What is the quality of Nissan Nissan?

Aside from national sentiment, I have driven two Nissan cars, one is Tiida manual transmission and the other is Teana. Now Teana is close to 1000 km. Generally speaking, I have the following feelings: First, it really saves fuel. Teana 2.5 self-priming, high-speed 6.4 oil, urban 8.5. A friend drives LaVida 1.6. Different displacement, but similar fuel consumption. Second, worry. I have been driving for more than 2 years before, and there is basically nothing wrong with it. So far, there has been no abnormality in Teana. There are few minor problems in the car, and the owner is very worried. Third, comfort. Teana claims to be a big mobile sofa, which is true. McPherson front suspension and multi-link rear suspension have excellent shock absorption and stability.

Of course, there are also shortcomings. First, operability. Volkswagen won at this point. The steering wheel is naturally light and feels inadequate. You can basically turn around with one hand. Volkswagen's steering wheel is very heavy and the circle is very accurate. Second, the car paint is thin. A little scratch, the car body is covered with scars. Third, practical functions need to be improved. For example, you must light the fire to close the window, but the key can't close the window. There is always something wrong with the connection between the mobile phone and the car stereo, so you can't listen to the songs in your mobile phone while driving.

I sell Nissan myself, only Dongfeng Nissan. If we talk about quality problems, we really seldom receive large-scale complaints. Before doing this job, I was a Honda driver and the owner of the seven-generation Accord. Now I bought two Nissan, which is worry-free, quiet at idle speed and convenient for long-distance driving.

If we really want to say the most impressive large-scale problem, it will be the 2.0 Scorpio gearbox of 2065438+August 2005. The owners of those cars did come to the store to change the gearbox, and the manufacturers recognized it, and the store did not hide it. After all, manufacturers also give us money. Who doesn't want to make it?

It is still very strange that hackers with the same power system have never had the same problem at all. At the same time, they all have the same configuration and suppliers, and only Qi Jun has experienced the intelligent key problem.

In recent years, compared with the defects of the product itself, it is actually the complaints from customers that make everyone more frightened. The previous generation of Qi Jun included hackers, except for the flagship version, which all had five-inch screens! In today's big-screen navigation, many customers would rather add money than choose the original navigation. Just last year, the manufacturer chose a 13 inch navigation as the original upgrade. It is this navigation that has brought us many complaints and maintenance. Let's just say that even we have been in court, doing, doing and being sued! And we heard that Highlander has a similar situation, because the store is forced to add decoration and navigation, so there are also many problems. Navigation, pedals, luggage rack! My own car doesn't even have a mat, let alone a film. This depends on personal choice.

Nissan is gradually becoming a mediocre and cheap car brand. Although its sales performance is not bad, its technical level and quality stability are declining. In the past, Nissan may be considered stable, comfortable and quiet by many people, but now Nissan has gradually become a second-rate Japanese brand, and it is getting farther and farther away from Toyota and Honda.

In 2020, Dongfeng will produce 1 133 186 vehicles a day, which is not bad from the data point of view, but the hidden dangers of Nissan have been highlighted:

1, relying too much on a single model, Sylphy's annual sales volume is 537,642, accounting for almost half. If Sylphy's sales volume collapses, Nissan's sales volume will be seriously affected.

2. Sales growth is too dependent on terminal concessions. Starting from Sylphy, Nissan's models generally have relatively large terminal discounts offline. Once the terminal discount is tightened, the sales volume will drop significantly.

Nissan has gradually changed from technical Nissan to cheap Nissan. For Nissan, everyone's impression has become a fuel-efficient and comfortable household grocery car, and Nissan's high-end models can no longer support higher pricing.

Nissan has become what it is now, which has a lot to do with one person, that is Ghosn, right, the guy who escaped from prison. Before becoming CEO of Nissan, technology Nissan was still a veritable technology Nissan. Nissan put forward the 90 1 plan, that is, it became the world's number one technology leader in the 1990 s and built the world's number one car model. Many older people's impressions of Nissan were also formed during that period. GTR, the Japanese god of war, swept the stadium, made 29 appearances and won 29 championships without any defeat. These two engines, VR series and RB26DETT series, are relatively well-known, one in the field and the other in the civil field.

However, the active pursuit of technology also makes Nissan's R&D cost too high and heavily in debt. The total net debt exceeds 2 trillion yen. Before Ghosn took over, Nissan was on the verge of bankruptcy. From this perspective, Ghosn is the savior of Nissan. He cut off the radical R&D strategy and introduced many cheap models, which enabled Nissan to regain cash flow and survive. Sylphy, Teana, Hacker and other models were introduced at that time. The similarities between these models are mature technology, comfortable and fuel-efficient, suitable for home use, and suddenly became an explosion. Nissan's annual sales volume climbed from more than 2.5 million vehicles in 18 to 5.52 million vehicles, and its market value climbed from the original1500 million dollars to 66 billion dollars.

However, Ghosn is also a grave digger of Nissan technology. Because of him, Nissan's strategy of becoming the world's number one technology leader was abandoned. Nissan's soul model GTR has not been replaced for more than 13 years. It is said that the next generation model will not be launched until 2023, that is, 15 years will be replaced. In addition to car models, Nissan's technology has also stagnated. Ghosn tried to improve the versatility of parts and platforms. In this way, the research and development of high-performance engines stagnated, and 1.6L and 2.0L self-priming engines with strong versatility and high sales volume were produced, which seriously dragged down the long-term development of "technology Nissan".

In addition, Ghosn began to cut costs to the extreme and won the title of "cost killer". He cut off models with poor sales, stopped upgrading performance cars, focused on models with higher profits and higher sales, and strictly controlled the R&D and manufacturing costs of vehicles, such as replacing electronic handbrakes with foot brakes, using engines with lower power, and even losing a reversing radar than others. But the powertrain of his model has not been updated for many years.

1, quality problems broke out. Nissan's CVT gearbox has a large area of quality problems, including Qi Jun, Heck, QX60 in Britain and finidi.

Nissan has become synonymous with cheapness. The actual price of Teana and Sylphy is lower than that of Toyota Honda of the same level, which is the second best choice for consumers.

When Ghosn left and Nissan launched the VC-TURBO engine, it was found that the times had changed, and Nissan's image had solidified, with strong power, acceleration of more than 6 seconds and low fuel consumption. Few people sought after it. 2.0 self-priming models are still the most popular, and Nissan has completely become a cheap brand.

Nissan still has some technical highlights. In addition to variable compression ratio engines, there are DLC coating technology, VVEL valve technology and e-POWER hybrid power. However, Nissan's problem is how to reverse its brand image. Honda relies on the Dream of the Earth and the IMMD hybrid car to maintain its technologically advanced image. Toyota relies on TNGA and THS hybrid cars to tell a good story. BYD DM-i hybrid was born, and polar krypton and polar fox shined at Shanghai Auto Show.

Nissan Nissan's car quality is poor-referring to the number of failures and PPH sales of major Japanese cars, Nissan is ideal. Sylphy used to be the sales champion of compact cars, and the sales performance of hackers and Qi Jun was also quite good; So the quality of these hot-selling cars is really good and the technical level is advanced?

The answer may be unexpected, and the unkind evaluation should be like this: Nissan has no other advantages except driving, and its overall technical level and product price positioning should be "industrial waste". It can sell well only because the Japanese automobile culture with Fujian, Guangdong and Qiong as its core is influenced by the automobile culture of Taiwan Province Province and Hongkong. The reason why Japanese cars in Hong Kong and Taiwan have a high number is because they are cheap.

Reference data 1: fault number ranking.

The top ten rankings of these failures are embarrassing, because most of them are joint venture vehicles; For example, 100% of the top ten compact cars are joint venture brands, and 1- 10 are Peugeot 408, sagitar, lavida, sylphy, yinglang, leading, excelle, civic, Citroen C4L and Toyota Corolla respectively.

In the face of joint venture brand cars, users are often surprisingly tolerant; However, the root cause is not really that these faults are nothing. In fact, we don't know what the standard of high-quality vehicles should be, and there is no comparative reference for the experience of other brands of vehicles, so we think that cars should be of this quality.

2.PPH ranking.

These data are collected by a third-party organization, but the data collected by this organization on a small scale is much higher. Because most media statistics on PPH will exclude "common faults" by default, such as engine vibration, gearbox frustration and so on, but aren't these faults?

However, even without these fault points, Nissan's overall performance is not ideal; The PPH of excellent cars and SUVs should be in the range of 50- 100, and cars are generally lower, because the main cars are simple front and rear drive systems, which is more worry-free than complex horizontal or vertical four-wheel drive SUVs. Therefore, Sylphy's performance is actually very poor. Teana's PPH is far from the number of faults, because Teana ranks seventh among the top ten medium-sized cars, and the other nine are Japanese, German and American joint ventures.

The real class engine is a serious injury to Nissan. For example, the "HR 16- 1.6L" engine used by Sylphy is still a multi-point injection technology, and the new 99KW/159N m level is low. The reason is, of course, that the injection mode of intake manifold can not achieve high-pressure injection, and a slightly higher pressure will cause wet wall problems.

In-cylinder direct injection technology is to inject fuel in a much larger cylinder, and the injection pressure can be increased to 350bar (gasoline engine standard) without worrying about wet wall, which is 65,438+000 times that of multi-point injection. High-pressure oil injection can control the droplet size within 10 micron, and the evaporation performance and combustion efficiency of mixed oil and gas will be much higher; High fuel efficiency means high engine torque, high torque and high power at the same speed. So Nissan can't build an in-cylinder direct injection engine?

Refer to "MR20-2.0L" naturally aspirated engine, which adopts in-cylinder direct injection technology; Therefore, it can't be said that Nissan can't make an in-cylinder direct injection engine, but can't make an excellent in-cylinder direct injection machine. Because the engine is equipped with Qi Jun, the phenomenon of insufficient combustion generally exists, that is, the exhaust gas emits black smoke, and the engine vibration problem is more prominent.

As for the KR20-2.0T direct injection turbocharger equipped by Teana, it is even more special. The machine adopts advanced mixed injection system. But the strange thing is the electricity data. The power parameter of179 kw/371n m (peak 4400 rpm) is ok, but the power curve feels different. Moreover, there have been some engine abnormal noise and even oil leakage problems, and the overall level is not high enough, so the sales volume of Teana is not very satisfactory.

Key points: Nissan QR25-2.5L engine is equipped on Qi Jun, Tuda and Navarra, but this machine is a joke; Power reserve133 kw/239 n m, the performance barely exceeds that of 1.0T supercharger, but there is a big gap compared with excellent in-cylinder direct injection 1.5T, because the maximum torque of 1.5T can reach 300n·m on the premise of equivalent power, which is a fuel-saving model of Miller cycle.

High torque is the basis of "low to high horsepower". Small torque can only be improved by increasing the speed, but high speed equals high fuel consumption. Therefore, if these cars want to save fuel, they can only lose weight, which is why Qi Jun uses plastic tailgate trims. The quality is really poor.

The continuously variable transmission (CVT) produced by JATCO- Jakot is quite poor, and there are three main design problems.

In fact, gear shifting frustration is a common problem of CVT, but it mainly appears in the deceleration and sliding stage; Because the bevel gear steel belt of the gear shifting structure cannot be disengaged, the engine will drag (brake) when decelerating. When you slow down to about 30km/h at high speed, you will feel sluggish, but when you reach this speed node, the braking force will disappear again. At this time, there will be a "rush feeling", which is basically a problem of two setbacks.

But strangely, Jecott's CVT also suffered setbacks in the acceleration stage, which is definitely a technical and quality problem. Secondly, CVT can't have abnormal sound, and the solenoid valve as the core unit can't have a high failure rate. As a consumable part, the AT solenoid valve with common model and much more complicated can basically have the same service life as the gearbox assembly.

Disadvantages: No matter whether the quality of CVT is stable or not, this machine has two major disadvantages.

1: The service life of the inclined wheel steel belt is very short, because shifting depends on the rolling friction between the three; The friction of any object will produce wear, which will reduce the friction coefficient of steel belt helical gear, thus upgrading from normal rolling friction to sliding friction transmission, and the service life will be shorter and shorter, and there will be problems of idling (power deterioration and oil consumption increase) in the process. After changing to CVT8, some Nissan cars may need to replace the gearbox assembly for tens of thousands of kilometers, and the high standard will be hundreds of thousands of kilometers. Some users didn't find the problem because they didn't have the concept of "getting lost" or were used to turtle speed driving.

2. Low temperature protection is the core shortcoming of CVT. Because the wear problem of bevel gear steel belt cannot be overcome, it must be lubricated with gearbox oil; However, when the automobile is cold started in a low temperature environment, the fluidity of the gearbox oil is very poor, and it is impossible to effectively lubricate the steel belt in a short time.

Therefore, after starting, we should start the car in place, and the idle fuel consumption of this hot car mode will increase by about 1 time, and insufficient combustion will also form more emissions and carbon deposits; Only vehicles with carburetor engines need local floor heaters, but this technology has been discontinued for 19 years. Then you have to idle for a few minutes or even ten minutes because of the gearbox. Does this car have quality?

Summary: CVT is only suitable for entry-level cars, because it has many shortcomings but low manufacturing cost, and it is acceptable for users with less mileage. However, it is unreasonable to use this machine in cars with a price of more than 6.5438 million, so it is unreasonable for mainstream Japanese car brands to choose CVT.

Nissan's engine technology is too backward, Teana's 2.0T is OK, but CVT is still in use; So far, it can be said that Nissan has no car worth choosing, and the hot sale is not the reason of the car itself. No matter how big or small the user base is, you don't know anything about cars.

How to answer! The first car I drove was a GM. Do you want to ask me if I will buy a car? My answer is never again. The second car is a Nissan, which has been in operation for three years. I should be qualified to answer your question. If I change cars in the future, I will consider buying a Nissan car. There are many people talking about Japanese cars on the Internet now. In fact, other cars exist, but there are two places in Japan that we should consider when buying a car privately. First, fuel consumption is really fuel-efficient. Everyone who drives it knows. Of course, do not trust the Ministry of Industry and Information Technology. Believe in yourself. Second, there are few problems, so don't worry. You can usually do maintenance. So if you have no free time at work, it is still recommended to buy Japanese products. Finally, I want to say that it is best to buy a self-priming engine with large displacement, such as 2.0 or above. The engine will not sound even if it is turned on for several years. Unlike the small displacement engine of 1.4t or the engine of 1.6t, the sound will be louder and louder after three years. Unfortunately, there are fewer and fewer cars with large displacement and self-priming engines now.

Advantages:

The space is large, and the longitudinal space is dominant in A-class cars. You can fight Tian. The height inside the car is also very good, just like the 307, which is a typical representative of the large head space inside the car.

Fuel-saving, there are basically about 7 manual gears in Beijing, and one oil is added to the automatic gear. The most fuel-efficient car in its class.

Quiet, with the help of sound insulation cotton and the low noise of the engine itself, the noise is already extremely low, whether it is idling or form. If the rotating speed exceeds 120, the noise will be great, mainly due to wind dryness.

Smooth, although it is a 4-speed automatic gearbox, smooth is better than the same level of 4-speed automatic gearbox, even better than the 6-speed automatic manual Cruz.

Disadvantages:

Thin skin, similar to Japanese cars, with plastic foam behind the front and rear bumpers. It's that a car shakes as soon as it passes, and the car itself shakes, so does the whole car.

Drift begins when the speed exceeds 120, especially after 140.

Maintenance is not cheap, compared with Elantra, maintenance is expensive, but compared with Cruz, Fox and other cars are also cheaper.

Brakes are not as confident as German cars. Although deep braking can achieve good braking effect, it feels a little unstoppable because of the small braking force in the initial stage.

I have a very good impression of Nissan, which is related to my driving Nissan Baning in 2003. At that time, I had been in charge for more than ten years. This car is in good condition. It has been in operation for two years after rectification, and there has been no trouble. Later, my company moved to Deqing. As a shuttle bus, I returned home with a full load every day and ran back and forth in Deqing, Hangzhou for two and a half years. It is very reliable. Another time, I drove my colleague Tiida 1.6, which was equipped with air conditioning (hot weather). I think the power is definitely poor, but the acceleration with one foot throttle is still very good. So, when my sister bought a car, I was the first to promote it. It's been six years now, and I'm not worried about falling apart. Finally, it is difficult to recommend a car, and I am relieved. If the recommended car keeps breaking down, I am embarrassed as an old driver.

I've been buying Nissan, and I bought Tiida on 20 1 1. Except for changing the wiper, there's nothing wrong with it. 20 15 hacker and 2020 Loulan are all redesigned by Nissan Loulan in terms of configuration, comfort and quality. In the meantime, BMW X3 also considered it and finally gave up.

My car is 10 Nissan converse, which has driven less than 40,000 kilometers. 12. Let's talk about the experience of using cars in recent years. First, I haven't used more than eight oils since I bought them. The power is still very fast in the displacement of 1.6, and the daily driving is quite brisk. There is room for pulling goods, especially the rear seats. Nissan's reliability is still very good. No problem. Besides maintenance, don't worry about breaking down. When driving, I feel that the engine sound is quite low. Converse is harder than other Nissan models in terms of shock absorption, but it is not particularly hard. It is related to the shock absorption at high speed, that is, when it is between 1 100 yards, the electric assist feels a little light. After 120 yards, it will be fine. I feel very confident. From 130 yards to 140 yards, I feel particularly stable. From 1 10 code to 120 code, the engine has sound, but it is unacceptable. I can't hear the engine when it reaches 130 yards. What are the disadvantages? There is also the abnormal sound of the plastic parts in the interior, which is also quite annoying. I don't know if the plastic parts in the car are abnormal, and the configuration is not high. People who buy this car are not rushing to configure it. It's converse's selling point.

For example, what is the quality of Nissan? I have worked as a sales consultant for Dongfeng Nissan for two years, so I still have some say in this respect. Let me show you what I have seen and heard. Many people are a little confused about the relationship between Nissan and Nissan. In fact, when Nissan entered China, it was called Nissan, which was translated from English. Later it was renamed. Just like Lexus, why are many people called Lexus? At present, the first-line Japanese brands sold in China are "Liangtian" and Nissan. Nissan's status and brand value are not as good as those of Toyota and Honda.

In fact, it is not that Nissan's technology and products are not strong enough. On the contrary, I think Nissan is more cost-effective than Toyota and Honda. Take SUV as an example. Nissan's main force is Qi Jun, and its sales volume is only a joint venture compact car with high attention. At the same price, Qi Jun's configuration is higher and richer. For example, Qi Jun sells the most comfortable version with the guide price of 19. Compared with RAV4 and CRV at the same price, there are more panoramic skylights, 360-degree panoramic images and leather seats. All Nissan models are known for their moderation, with no outstanding advantages and no absolute disadvantages. Everything has been weighed.

I think the only thing that stands out from Nissan is comfort. It is said that Nissan buys sofas to deliver cars. At this point, Nissan's seat design is indeed wider and thicker than other brands of seats. The most proud thing is the "zero gravity" seat on Scorpio, which is comparable to first class.

In recent years, Nissan's design tends to be younger and more sporty. In the past, the rigid and business image has been lost in Nissan's new car. At present, Nissan complains more about gearbox oil leakage and engine oil burning. When it comes to burning oil, don't misunderstand that it is as serious as a German car. In fact, all brands of cars are slightly burned with engine oil, depending on the quantity. The oil burning situation of Nissan is not a common problem, but a production batch problem, and most of them do not have this problem. Dongfeng Nissan now has four major factories in Huadu, Xiangyang, Zhengzhou and Dalian. According to internal sources, the quality control of cars produced in Xiangyang is the best, so when buying a car, you can pay attention to where the car is made. Nissan has entered the China market for a long time, and the older generation of Teana, Sylphy and Bluebird can now be met on the road. There is no doubt about the reliability and durability of the car, which is absolutely not worse than Toyota and Honda. On the contrary, Nissan is more affordable, richer in configuration and more cost-effective. In Toyota Honda Nissan, I definitely choose Nissan. All of the above are about cars, regardless of national historical factors. I hope it helps you. Thank you for browsing!
