Patent technology of double needle desensitization

It is also 3. 15 a year. As a legal consumer rights day, it often attracts much attention. Among them, with the constant disputes caused by the surge in domestic car ownership this year, automobile products have become the focus of consumer rights protection.

Looking back on previous years, such as 20 10, the car 4S shop only changed and did not repair;

20 12 Jin Hu tires were shoddy, and the hidden rules of 4S shop deducted the card to turn the new car into a black car;

20 13, DSG power shift was exposed to potential safety hazards, and JAC was caught in a "rusty door";

20 14 elderly scooters are shoddy, illegally produced and driven on the road;

2065 438+05 4S shop overhaul profiteering, Land Rover Aurora transmission exposure;

20 17, second-hand car trading is a scam;

20 18 Volkswagen Touareg is afraid of "getting caught in the rain" and engine failures frequently occur;

In 2020, the problem of SAIC-GM-Wuling gearbox is "endless";

202 1, BMW 4S shop "compulsorily" collected face information, and the gearbox of Changan Ford was flooded, and the gearboxes of England and finidi rattled.

The "absence" in 2022 caused more people's dissatisfaction with "why there are no new energy vehicles". You know, according to the data recently released by the General Administration of Market Supervision, with the rapid increase in the penetration rate of new energy vehicles, the number of complaints and reports about new energy vehicles received by the platform increased by 63% year-on-year, which is why new energy vehicles will appear this year and why it is worthy of attention.

Of course, the answer will not be revealed until the evening, but what we can know at present is which models have been recalled due to the safety problems of automobile products since March15 last year and why. The recall notice issued by the Defective Product Management Center of the State Administration of Market Supervision shows that from March 2022 to March 2023, domestic cars issued recall notice 144 batches, and a total of 3,538,900 defective cars were recalled, down 63.74% year-on-year.

On the whole, the largest recall in the past year originated from the failure of domestic Tesla's parking light software, involving more than 430,000 vehicles, accounting for 12.30% of the total recall. Tesla also topped the domestic recall list because it recalled 760,000 faulty vehicles in China five times.

It is worth noting that during the above period, due to the defect investigation by the General Administration of Market Supervision, a total of 15 vehicles were recalled, involving 663 10000 vehicles, accounting for 18.74% of the total number of recalls in the same period. Among them, BMW Brilliance Series 5 may have a black screen in the instrument cluster due to software problems, involving the recall of 17 1828 faulty models, occupying the first place.

For example, focusing on the overall cause of recall failure, with the continuous iteration of technologies such as vehicle electrification and intelligence, the new recall problem is gradually replacing the traditional hardware failure as the main body, which is bringing more complicated problems in defining the responsible party.

The recall of new energy vehicles has risen, and powertrain-related failures have attracted attention.

As mentioned above, the most regrettable thing about the 3. 15 party in the past two years is that new energy vehicles have not been listed.

As we all know, since 20021,the sales of new energy vehicles in China have made rapid progress. According to the latest data of the Federation, in February 2023, the penetration rate of new energy passenger cars in China exceeded 3 1%. Not surprisingly, the era of energy-saving and new energy vehicles is coming quickly.

However, according to the complaints recently released by the General Administration of Market Supervision, in 2022 alone, the platform received 6,543,800 complaints and reports about new energy vehicles, among which contract problems, quality problems and false propaganda problems increased rapidly, with year-on-year increases of 654.38+0.26.33%, 77.35% and 75.65% respectively.

Reflected in the recall ratio, from March 2022 to March 2023 14, the recall ratio of defective pure electric passenger cars in China was 25.8 1%, an increase of 267. 1 10,000 vehicles. Expanded to the full range of new energy passenger cars, more than 6,543,800 faulty vehicles were recalled during the above period.

In addition, the number of hybrid vehicles in energy-saving vehicles decreased compared with the same period, and the recall involved 2 1.52 million vehicles, accounting for 6. 12%.

In addition to the electrical equipment related to headlights, the failures related to powertrains such as power batteries, electric drives and engines are also rising gradually. Among them, the three new energy vehicle brands involved in the recall: Tesla, BMW and BYD all recalled power batteries.

In addition to Tesla, BMW and BYD, which account for the absolute share of the total recall of new energy passenger cars, the recall of bZ4X, Toyota's first modern pure electric vehicle, also caused heated discussion.

According to the news from the General Administration of Market Supervision, Toyota will recall over 65,438+2,000 bZ4X vehicles from 1 in March 2023 due to improper internal procedures of the front camera of the driver assistance system. Among them, FAW Toyota recalled some bZ4X cars produced from September 6, 2022 to February 2, 2023, totaling 6,265,438+03 vehicles; GAC Toyota recalled some bZ4X vehicles produced during June165438+1October 65438+May 2023, totaling 6 159 vehicles.

You know, according to the terminal data of Geshi Automobile Research Institute, since the listing of FAW Toyota and GAC Toyota last year, the cumulative sales volume is less than 4,000 vehicles, which means that the bZ4X involved in this recall will cover all wholesale quantities, including sold, spot, exhibition and test drive.

In fact, this is not the first large-scale recall of Toyota bZ4X. In April last year, Toyota bZ4X was the first to be listed in overseas markets. Only one month later, Toyota recalled it around the world, because the wheel hub bolts on the wheel may loosen during driving, causing the whole wheel to fall off. Therefore, Guangzhou Automobile Toyota bZ4X, which was originally scheduled to be listed on June 17, was forced to postpone.

This bZ4X large-scale recall may be combined with the delayed listing of Volkswagen's first electric car ID.3 for many times due to software problems, and the frequent automobile problems in the domestic market, forcing people to pay attention to the fact that the advantages of foreign traditional automobile giants are rapidly weakening in the face of smarter and more technological struggle in the second half.

Software problems are rising, and new automobile technology has become the focus of sandbox supervision.

In recent years, with the rapid development of automobile electrification and intelligence, the causes of automobile recall have extended from traditional hardware failure to system program and software design problems, showing a diversified trend.

In the past year alone, more than one million cars in China were recalled due to the failure of headlights, infotainment and electrical equipment, accounting for 33.9% of the total recalls in the same period. And there are as many as 6.5438+0.68 million defective vehicles related to system programs and software design, involving 654.38+08 car companies such as Tesla, BMW, Hyundai, Toyota, Kia and Mercedes-Benz.

In addition to the failure recall of HECU of Hyundai Motor Group and the related failures of Tesla position light software mentioned repeatedly above, more and more attention has been paid to the auxiliary driving-related failures such as body stability control system and lane keeping assist system.

Among them, Toyota announced on April 22 last year that due to the imperfect internal procedures of VSC (Body Stability Control System), it recalled the domestic high-performance version of Highlander, the brand-new fourth-generation Highlander, Seine, Visa Twin Engine, Crown Fang Lu, RAV4 Room Rong, Fang Ling and imported Mirai, Lexus NX350h and NX400h+ from May/0/.

In addition, the program fault recall related to millimeter-wave radar sensors, forward-looking wide-angle cameras, front-facing cameras and other auxiliary driving sensors has also received continuous attention.

By 2023, it is considered that China Automobile will officially enter the competition in the second half of the year, and the era of intelligent electric vehicles will come soon. More software-related failures such as assisted driving are inevitable. How to nip in the bud and further protect the safety rights and interests of consumers is particularly important.

On the eve of March 15 last year, the General Administration of Market Supervision officially issued the Notice on the recall of automobiles and consumer goods in China in 20021year, which summarized the recall of automobiles and consumer goods in China in 20021year and pointed out the work direction for the future recall. In view of the new development trend of intelligent networking technology, a perfect data-driven in-depth investigation system of automobile accidents is proposed to deepen the OTA big data security assessment of smart cars and start it. Subsequently, the Notice on the Trial Supervision System of Automobile Safety Sandbox was officially released in April.

Just a few days ago, the General Administration of Market Supervision will steadily promote the supervision system of automobile safety sandbox, and make it the first task of market supervision modernization in 2023 and the "14 th Five-Year Plan" to ensure that the innovation system is safe, moderate and controllable.

In the first batch of automobile safety sandbox supervision technology catalogue, new technologies such as new electronic and electrical architecture, on-board chip technology, on-board data desensitization technology, high-power charging technology, new generation power battery technology, and new functions such as assisted driving and automatic driving are all in it, thus promoting enterprises to continuously improve product design and manufacturing and reducing product safety risks.

After a year, it's 3. 15 again. It is expected that the General Administration of Market Supervision will introduce more advanced and grounded regulatory measures, explore the new idea of "finding product defects-making suggestions on product safety specifications-realizing quality improvement", and promote enterprises to continuously improve technology and quality in design, production and after-sales service.
