Various media reports Tesla accidents almost every day, and almost every day says that Tesla's brakes have failed. If you count the number of answers and likes, almost 95% of the participants believe that Tesla's brakes have failed. And this result is completely contrary to the survey results of national authorities, why? Could it be that the authoritative department is not as good as a few laymen and a few self-media professionals?
Then bring out these problems of Tesla's brake failure one by one, and first pull out all the complaints about Tesla vehicle problems on the vehicle quality network over the years.
The Model 3 was just launched in 2017, so I didn't pull the data before 2017
The number of complaints that can be seen is:
There were 18 complaints about imported Model 3s
There were 27 complaints about the domestic Model 3
In addition, there were 51 complaints about Model Y (including 45 complaints about body resonance, so I won't talk about it)
Click on the analysis of the problem of Model 3 complaints:
The imported version of the Model 3 brake system complained about 2
There were 3 complaints about the brake system of the domestic version of Model 3
That is, there are a total of 5 complaints about the brake system of the Model 3, and the total sales of the Model 3 so far are about 200,000 units. That is, the complaint rate of brake system problems is about 0.25 per 10,000, or 0.0025%.
Let's expand on the details of the complaint
The first complaint of the imported Model 3 brake system is that the brake pads are cracked and do not deploy
The second complaint about the imported Model 3 braking system is as follows
This is a little at a glance to know that the owner pressed the accelerator and brake pedal at the same time to cause the alarm, do not explain
Then look at the details of the complaint in the domestic version
First complaint details
The front says that the vehicle accelerates instead of decelerating when the brakes are applied, and the latter says that AEB starts emergency braking and ABS starts. Since the brake pedal does not brake when pressed, how to brake later? If you understand the structure of the brake system, you know that it is completely impossible. The previous reason can only be that the accelerator was stepped on by mistake, or the AP was started by mistake.
Details of the second complaint
It is not clear what caused this phenomenon, but it is clear that the brake system failure warning prompt is clear and complete.
At least this complaint can be counted as a case study of whether the brake system is defective, and it needs to be known in detail.
Details of the third complaint:
Needless to say, press the brakes and accelerator at the same time, and blame the brake system failure.
I also went to see the Model Y's complaint
There are no complaints about the braking system.
That is, adding up all the Model 3 and Model Y, there is only one complaint in the country that the brake system failed and alarmed. Two of the other complaints were driver misoperation (brake throttle pressed at the same time), one was cracked brake pads, and one was a failure that was obviously impossible (first the brake was ineffective, then the brake was started and the ABS was started).
There is no need to question the possibility of this brake accelerator being pressed at the same time, the sensors are originally multiple sets of mutual backup and verification, and it is impossible for multiple sensors to have the same numerical error. Simple technical means can ensure the accuracy of data, and third-rate engineers can do it.
Then I searched for domestic pure electric vehicles
I'll pull the clock back to 2019
Then casually rummaged through complaints about brake failure
Surprised or not surprised?
Let's talk about self-media, first of all, the first real hammer of a platform big V Xiaogang senior fake Tesla brake out of control
Even if Tesla wins this brake failure, isn't it the trust of the public that it loses? 53 Agree · 34 comments answered
From 1:35 to 1:39 in the video, the emergency braking function is deliberately canceled by pressing the accelerator (throttle indicator bar) firmly before (or during) the start of the emergency braking of the collision. Then fabricated that Tesla's automatic emergency braking failed.
There was no wave on the Internet, and Tesla brakes that were not hammered failed, and the sound on the Internet rose and fell one after another.
YYP that test ended up with nothing, and was hit by a group of ignorant hammers Tesla brakes failed.
Wang Yin's test, except for stealing the concept, the brakes stiffened without even a detailed description. Then it couldn't stand up to doubt, and the video posted on Weibo even deleted the brake hardening
What do you think of the video blogger "The Boundless King" test and speculation about the hard brakes of Tesla Model 3? 72 Endorses · 199 comments answered
And if Wang Yin does not measure the air quality inside the Model 3 this time, it is difficult to say whether he has been recharged. And this test just proves that he has been recharged.
One is to deliberately obscure the Model 3's production date. The two are the only acetaldehyde exceeding the standard, it can be said that almost all cars exceed the standard (it can only be said that the Han EV performs well, but it does not mean that the Model 3 is lower than the level of similar cars). The third is that when the previous test said that the acetaldehyde index was not important, this time I came to hit myself in the face.
The Hainan wall collision incident is obviously caused by the driver pressing the brakes too lightly, and tens of thousands of rear-end collisions occur across the country every year, is it caused by brake failure?
In fact, the available statistics show that Tesla's accident rate and death rate are much lower than traditional cars
What did you see behind the Tesla incident during this time? 244 Endorsements · 468 comments answered
In China:
Tesla used about 8 ten-thousandths of the country's motor vehicle ownership and contributed to an accident rate of less than 2 per 10,000.
And the accident fatality rate is much lower than average
In the United States:
Owners using Autopilot saw an average of 10.5% fewer accidents per 4.19 million miles traveled. Owners who did not use Autopilot but had active safety enabled had an average of one accident per 2.05 million miles, up 3.0% year-over-year; Owners who didn't use either Autopilot or Active Safety averaged one occurrence per 978,000 miles, down 31.1 percent year-over-year.
By comparison, the latest data from the National Highway Traffic Safety Administration shows that there is one car collision every 484,000 miles in the United States. Tesla's safety is recognized by NHTSA.
As I said before, a group of talents in the automotive field do not think about how to build a good car, but think about how to turn competitors down every day
There are also those rumors that are constantly being circulated: Ping An Bank does not renew Tesla's warranty, a certain lot in Guangzhou prohibits Tesla from passing, a parking lot prohibits Tesla from entering, Tesla peeps into user privacy, Tesla provides XX to the United States through body cameras and radar scanning terrain, and even says that Tesla will be stopped production and sales...
The fundamental reason is that there are too few people and enterprises in China's auto industry who really build cars with heart. If you can make money steadily, almost no car companies will think about how to optimize vehicles, but how to please users and sell more cars.
There is also the problem of not throwing the pot to the equipment, even if the production line equipment of its own brand car factory in China is the most advanced in the world, the processing accuracy is no different, as long as you are willing to buy the material, someone will sell it to you.
Even if the same production line (the same equipment, the same workers, the same process), such as Hongqi HS5 and Audi Q5L co-production, many models of Brilliance were produced by BMW's production line. But when you open it, you feel that the gap is big, and the problem is that the design level is too low
The biggest problem facing China's market economy is bottomless competition, and bad money eliminates good money
1. Quality problems, as long as there is no accident, everything will be fine, and strict quality standards are not observed
2. There is no bottom line bidding, I can sell 9 pieces if you sell 10 pieces, and I will sell 8 pieces if you sell 9 pieces. But what if I cost 8 pieces? Optimize BOM, reduce functionality or quality standards, and reduce costs; What if it doesn't work yet? First low and then high, and then increase the price when the business is ripe; What if this trick doesn't work? The loss in the west is made up in the east, and here the loss is made up from elsewhere; What if none of them work? Change the routine, turn procurement into PPP, play capital, if you don't pay, I will pay ... In short, according to the wisdom of the Chinese people, there are always infinite ways to obtain the market without improving the quality and product competitiveness.
3. The concept of intellectual property rights is lacking, the protection of intellectual property rights is too small, and the cost of rights protection is high and the return is low
4. Short-sightedness and only consideration of short-term interests.
5. The market capacity is large, and you can lie down and win for a period of time without seeking progress. Often many companies are this kind of thinking, do not want to upgrade products when the market is good, and when the market is bad, go to other industry ideas, cross-field operations.
Can you take a look at the world's famous high-end manufacturing enterprises, how many companies operate across many fields? And our manufacturing enterprises, cross-field not too much, real estate belongs to the basic routine, finance can be stained, IT Internet can cross. Diversifying investment across sectors will affect the confidence and conditions for upgrading in the manufacturing industry.
