Introduction | Things originally such a
more and more out of control, let the car circle fall into an unprecedented fear.
According to the description of the owner of multiple Model 3, there is two types of loss: one is sudden automatic acceleration, and the other is the brakes. No matter which type, it will bring fatal safety hazards.
First, inside the charging station, suddenly accelerate!
January 26, a car owner posted in the forum: In the morning, he opened his 2020 Model 3 long-lived version, and entered the charging station to charge, the speed is very slow. The previous line and played a 45-degree direction, then loosen the electric door, preparing the brakes and poured into the charging bit. “At this time, the vehicle suddenly accelerated. At that time, the head was 懵!”
The owner is still full of fear, because the feeling of feelings is indeed But not human stealing, but
pedals go to
. Because of the peace of the electric door, it is completely different.
When the reaction came over and stepped on the brake, the car had hit the opposite wall.
The owner said that he opened a 7-year car and there was absolutely no operational mistake. After Tesla learned, it would be a full-time accident photo, and it is necessary to analyze and guarantee that the driving record is not deleted.
Second Day Tesla sales, give preliminary conclusions: There is no problem with the acceleration and braking of the vehicle . After the collision detected that the accelerator pedal was suddenly stepped on, although there was a brake action, the distance collision was only 0.2 seconds, causing an accident.
The owner finally said: “As a special powder, I deeply suspect that every accident is the driver stepped on the buckle,
Only who he had experienced it, I found it really likely Tesla. Question
. “
Second, in the area, sudden brake failure! On February 1, Mr. Zhao, which is the special powder, has encountered another wonderful fault: the brakes do not move.
He likes Tesla from the beginning, and finally set a Model 3 performance. But didn’t expect, after the car was only a week, there was a situation in the brake failure!
At the time, he had a prompt “Energy brake assist effect decline” on the screen, and he thought it was only limited to energy recovery. The case, stepped on the brakes, still did not release the brake pedal,
The car actually goes forward
! Moreover, the brake pedal becomes particularly hard, because the feeling of enthusiasm is put on the brakes, and when they step on it, there is a braking force to stop the car.
“At that time, there was a sound in ABS working, and the brakes were particularly hard, and there were no brakes in the first quarter of the stroke, but the brake lights were bright.” 
[ 123] After the sale, Tesla staff
told him that it is a system problem
. But he raised the car during the week, and there was no time, etc.
As a senior special powder, Mr. Zhao started a variety of restarting Dafa on the spot, and he did not stop getting on the bus and stepped on the brakes. Finally, the brake pedal is recovered. However, the abnormality is:
The front brake is completely imaginary , without any resistance, it can step on it. After reaching a critical point, the braking effect suddenly appeared.
He has issued a question on Weibo:
▎ If it is a system problem, why not update the new car update system? Why is another owner updated the system still problem? Why did his car still do not update the system?
Another Ningbo riders are also a domestic performance version. They also encountered the problem of braking steps. After the sale is a system problem, but the maintenance measures are replace the imported Ibooster
?
What should I do if this brake failure occurs on the high speed? He received a private letter of four riders and said that the same brake fault!
Why is such a high failure rate?
? ! Among them, the mystery has to be found from the maintenance order.
Third, the maintenance order, the problem points refers to iBOOSTER!
According to Mr. Zhao, it is displayed that the maintenance measures for Tesla on brake failure problems are: Replace IBST – This is the English abbreviation of iBOOSTER.
Main Accessories: The number of the vacuum booster and the master cylinder assembly is
1044671-50-a .
The payment method is very interesting: good faith.
This is another maintenance order for another Ningbo Model 3 performance. His family was started normally in the parking lot, and the vehicle suddenly accelerated. It was not used in normal step on the brakes. Finally, the whole person must stand up to stop. Hanging a P-stop is also useless. Once try to release the brake, the car has an accelerated trend. The problem is still: “
IBOSTER problem, after replacing troubleshooting
.” 
The final store’s measures are: putting domestic brake booster pump (IBOSTER) is replaced with
imported accessories , and there is no similar failure.
It is worth noting that the owner’s part number is
1044671-00-E .
More more interesting is that the payment type is: a limited quality assurance of the vehicle.
Then the problem is coming: Why is the Model 3 performance version, all the same fault, all in Ningbo repair, but give the accessories different? 
The second maintenance order is too early, on January 27 this year. According to the owner of the owner, it is changed to the imported iBooster. It can be seen from the last character “E” of the number, which may be the meaning of Europe.
The date of the first maintenance order is February 2nd, according to the carMr. Zhao description: He changed domestic parts, but the new version. The last character of the fitting number is “a”, which may be the meaning of Asia.
Why gave him a domestic version of the accessories, Tesla maintenance personnel explained: The old version of the owner was replaced by the old part, The number was not afraid of compatibility
. They deliberately took an
new version of the domestic part of from another Journey to another service center to give him.
Car Jun Jun Wen Yan: The compatibility of the owner before, Tesla still tuned? Which of the maintenance of the owner is so casual? Do not fully verify that the owner is tested? Moreover, the payment method is a limited warranty for a while, and it is a good idea.
No matter what to say, the above two maintenance orders can be drawn: dozens of Tesla uncontrolled cases since 2020, seems to have an answer:
Bosch iBooster
. 
According to reports, in 2013, Bosch’s first generation of iBooster was produced in German factory; in 2017, this part giant began to produce second-generation iBooster. In March 2019, Bosch iBooster Nanjing production base was enabled and named the product:
Intelligent booster
.
Nanjing factory is the third iBooster production base after Bosch, Mexico. Mainstream manufacturers such as Sla, BYD.
The most problem is the most problem of Tesla’s model
. Why have we not updated 2021 incidents? Because too much ! Can’t remember!
In this case, the car is called for: Please invite the State Market Supervision Administration to intervene in the investigation to determine whether the iBooster of Tesla’s model is batch defects? And to Titra in accordance with the “Recall Ordinance” to submit defective product analysis reports, determine the reason and effective solutions, can no longer take users to tryLook!
Four, not only Tesla, multiple cars use iBooster!
Is there a problem with Boso iBooster, is domestic or imported? 
This is a complex problem. On the one hand, Tesla is replaced by the owner of January, indicating that they have more recognized the quality of imported iBooster.
On the other hand, according to the list of 2020 incidents, Nanchong 2 deaths and 6 injuries, and Chengdu hit three car cases. The models are model x; Beijing Bisen rushing event and Shenzhen rear-end taxi incident, The models are Model S. They are all imported cars, which is naturally imported iBooster, but there is a failure! So, it is also related to the version of iBOSTER. Why is this in February, Tesla has given a new version of domestic iBooster to Mr. Zhao.
In any case, this event is likely
like the high-grade airbag , which will involve most of the world’s car companies. The reason why Tesla’s “out of control doors” is probably related to quality attitude towards quality. Elon Musk has recently recognized:
Due to the high production speed, there is a quality problem in vehicle, and it is recommended that users do not purchase
when the production capacity climbs
.
The frank rate is frank, but the big brother! Cars are not mobile phones, its quality is related to people’s lives! In order to climb the quality of the world’s richest, some users may sacrifice the sacrifices of life into faith! Is this going to “one will become a harder”?
You have money, can not trample on the law ?
It seems that five departments of the State Market Supervision Bureau have recently discuss Tesla, and there is an authority!
At the same time, it is also recommended that the State Council is closely concerned about whether the IBOOSTER product of Bosch has a source of originability? A simple reasoning is that if Tesla’s after-sales believes that “new version” can solve the problem, then explain Tesla and Bosch know the problem and do the corresponding update !
But all of these updates seem to be secret between Tesla and Bosch, is not sure whether they submit relevant reports to the State Market Supervision Administration?
Car Jun Jun has doubted the Bosch’s iBooster, expressing doubts on Weibo. Another media that I was familiar with Bosch asked its executives, and the answer to the back is:
Hu Yan
.
The words of the manufacturer, listen to even.
Ideally start quietly replacing new ball sales on June 2, and I have vowed to claim that the product has no quality problem in August. On November 6, I will recognize the problem and recall. What happened first, not there.
A reality is: The 56% of the recall in our country is ordered to recall , although the surface is “active recall”.
According to the reader report, there are two uncontrolled accidents, one case in the underground garage, is considered to be the cause of epoxy floor, and the other, the parking lot, low speed Suddenly, the wall – this is no longer a pot of epoxy floor, water stains, speed?
In addition, BYD also has several out-of control events. On April 23, 2019, a Tang DM in Xi’an lost control in driving, causing a death and five injuries. Although the official confirmed is that Ms. Week is not operating, she has put forward strong questioning on the
abnormal data
in the accident appraisal report.
On January 19, 2021, a Han EV parked in the exhibition hall in Hanzhong, suddenly lost in the camera, high-speed flying out of the stall, dangerous.
Even the car gathered when testing a self-owned brand electric car, there was also a rainy day, stepped out of ABS but the speed of the car was obvious. Not ABS normal brake distance is extended, but
brakes are invalid and significantly speeding
, fortunately, after a few seconds, it returns to normal accidents.
The above vehicles use Bosch’s iBooster. 
carSummary
Mr. Zhao sighs: I have always been Tesla’s iron powder, I have always believed Tesla, and even when there is an out-of-control report, it will also analyze the reasons for the driver. For example, the Beijing owner @ 电动 老 – – the lover driving Model 3 out of control, he is standing in Tesla, until things happen to himself.
“” What kind of experience is it to help your brand? “He asked.
@ 电动 老王 – happened to see it, this certification is comforted by the owner of the navigation engineer: Thank you for remember me.
When things happen to themselves, they will be aware that they are not necessarily the owner
. Mr. Zhao finally said: I cried, it is really a crit.
It is desirable that Tesla is in response to the response, systematically investigate, and effectively implement consumer rights protection. . Don’t let users be shocked and tears.
