Tesla has been hit by the heavy hammer of US regulation!
In recent years, with the popularity of pure electric vehicles and the advancement of autonomous driving technology, Tesla has become a leading brand in the era of new energy vehicles.
But at the same time, more and more of Tesla's problems began to be gradually exposed. One of the most serious problems that has been exposed is Tesla's brake problem.
No, recently because of the frequent "ghost brake" problem, Tesla has not only recalled many sold vehicles, but also once again been subjected to the heavy hammer of supervision!

The brakes have become a fatal flaw for Tesla!
According to the Washington Post, in recent months, Tesla has frequently seen "ghost brake" incidents, and the number of complaints alone in 3 months has exceeded 100.
The so-called "ghost brake" refers to the fact that if the owner opens Tesla's own L2 automatic driving system during the driving process, there will be some automatic braking behavior of the car without warning.
Imagine if you are driving at high speed on the highway and the car system suddenly brakes, then it is likely to cause a series of rear-end collisions in the rear car, and the consequences may be fatal.
But these Tesla "ghost brake" events are not completely without reason, because Tesla and most other new energy vehicles use multi-sensor cross-check scheme is different, Tesla is using pure visual autopilot, and there is no millimeter wave radar installed, so if you float in front of a plastic bag, or other lanes of the car because of the shadow cast by the light may lead to the automatic driving system to misjudge that there is an obstacle in front of the car or the car, causing the system to misjudge the automatic emergency brake.
In this regard, Phil Kupman, a professor at Carnegie Mellon University who focuses on the safety of self-driving cars, also said that the reason why Tesla will frequently appear "ghost brake" events is because Tesla's developers have not made the correct threshold setting for "false alarms", resulting in the system is easy to cause false judgments.
With the gradual increase in "ghost brake" complaints, the relevant regulatory authorities in the United States have recently opened a comprehensive investigation into Tesla on the "ghost brake" incident.
It is worth mentioning that some media reports show that some Tesla owners in China have sporadically appeared in the "ghost brake" situation.
Affected by the involvement of US regulators in the investigation, Tesla's stock price on February 17 also fell 5.09%, evaporating more than $48.6 billion in a single day, shrinking to $905.7 billion.
It is reported that the Tesla autopilot assist system investigated by the US regulatory authorities includes some models of Tesla's 2021 and 2022 Model 3 and Model Y models, a total of 416,000 vehicles.

"Ghost brake" is just one of Tesla's many quality problems, Tesla quality problems are frequent, people worry!
Because of serious quality problems, Tesla has recently fallen into a "recall wave". According to the news released by the State Administration for Market Regulation on February 18, Tesla (Shanghai) Co., Ltd. recently filed a recall plan with the State Administration for Market Regulations in accordance with the requirements of the Regulations on the Administration of the Recall of Defective Automobile Products and the Implementation Measures for the Administration of the Recall of Defective Automobile Products.
It is reported that Tesla will recall 26,000 domestic Model 3 and Model Y vehicles within the Scope of the Chinese Market. Behind the large-scale recall is that there will be a slight movement in the positioning of the electronic expansion valve of the heat pump of the above two models, and if it moves for a long time, it may cause the valve part to open, so that the heat pump compressor stops working, and eventually the vehicle cannot be heated.
When the vehicle's heat pump compressor stops working, if the vehicle is driving in an area with low temperature outside the car, frost will appear in the front windshield of the vehicle, which will seriously obstruct the driving vision of the driver and increase the probability of a car accident.
It is worth mentioning that this is not the first time tesla has recalled sold vehicles in the Chinese market. As early as Last December, Tesla also recalled two sold vehicles in the Chinese market. Among them, the number of vehicles recalled in the first time reached 21,599, mainly involving the problem of steering knuckles, while the number of vehicles recalled in the second recall reached 144208, mainly involving the problem of trunk cover.
Compared with the number of recalls in the Chinese market, tesla's recalls in the US market are even more amazing. According to relevant media reports, according to incomplete statistics, in less than a month from January to late January this year, tesla recalls in the United States reached 4 times, involving more than 1.47 million vehicles. In February, Tesla recalled 578,600 electric vehicles again due to vehicle audio problems.
It can be said that recalls have become a common thing for Tesla now, and there will always be a little problem in a few days. This can be seen in Tesla's recall data for the Chinese market for the whole year of 2021. According to the data, Tesla recalled a total of 543,800 vehicles in the Chinese market alone in 2021, accounting for 58% of Tesla's global sales in 2021. It can be seen that Tesla's vehicles with quality problems have exceeded more than half of its sold vehicles!
In fact, Tesla's frequent quality problems today have long been a well-known fact. As early as last year, Musk personally admitted that there were problems with Tesla's quality control, and even bluntly said that "our production is like hell."
This is also understandable, after all, a penny for a penny, Tesla is not a charity enterprise, so with the crazy price reduction and huge order demand of domestic Tesla in recent years, Tesla's quality control problems will certainly be greatly discounted.
Even so, Tesla after the price reduction still embodies the law of "true fragrance" and is extremely sought after by consumers.
But in the end, no matter how fast technology develops, it cannot override life. Therefore, staying away from Tesla may be the wisest choice.
