Recently, the comprehensive recall information released by the State Administration for Market Regulation shows that a total of 14 domestic car companies and 42 models have been recalled for filing, involving a total of 386,100 vehicles, a month-on-month increase of 66%. Among them, the number of recalls of new energy vehicles reached 112,400, accounting for 29.12% of the total. Since the beginning of this year, many new energy vehicle companies in the domestic market have recalled vehicles due to potential safety hazards caused by product technical defects.

｜Active safety functions need attention, "three major" failures are still the focus

In the first half of 2022, the number of recalls related to car active safety functions ranked first in terms of recall reasons, involving body stability control systems, lane assist systems, pre-collision systems, etc. Once these functions fail, it will reduce driving safety. As more active safety functions are applied, major car companies should pay more attention to improving the stability and reliability of active safety functions.

In terms of fuel vehicles, related failures of major components such as engines, transmissions, braking systems, and fuel tanks are still the focus of the problem.

Specifically, in the first half of 2022, the number of recalls involving the transmission and braking system reached 6, and the number of recalls related to the engine and airbags reached 5. These faults may cause the vehicle to lose power and leak oil in the transmission. , increased braking distance and other issues, consumers must pay more attention to the usual car use.

In addition, with the continuous improvement of automobile intelligence, recall measures involving vehicle system failures have also increased significantly. Mercedes-Benz, Tesla, etc. have recalled many vehicles due to central control screen failures. In the future, more cars may be recalled due to faulty vehicle systems.

It can be seen that as electrification and intelligent configuration become more and more common in automobile products, the failure of automobiles is not only related to the "three major components", but also more related to vehicle-machine systems and intelligent assisted driving hardware, which also shows that Major car companies cannot simply stack functions, but also improve the manufacturing process and stability of related components.

｜Although the sales of new energy vehicles are gratifying, their problems are becoming more and more obvious

In the first half of 2022, my country's new energy vehicle sales reached 2.6 million, a year-on-year increase of 1.2 times, and the market penetration rate reached 21.6%.

Data show that in July, the number of recalls of new energy vehicles reached 112,400, accounting for 29.12% of the total. Among them, Ford recalled pure electric models, BYD, BMW and Kia recalled plug-in hybrid models, and Maserati recalled 48V mild hybrid models.

It is worth noting that with the gradual increase in the number of new energy vehicles, the problems of new energy vehicles not only stay in the power system, battery system and electric drive electronic control, etc., including functional design and assembly quality may become recalled. reason.

For example, the recall of Ford Mustang Mach-E is related to power system control module software and battery control module software; Kia K3 plug-in hybrid model may not meet emission standards due to unreasonable ECU data design; It is on the fixing bolt of the 48V battery.

In addition, there is a trend from hardware to software for recall reasons.

In the recall measures in the first half of 2022, a total of 11 recalls were completed through OTA remote upgrades, including 4 times for Mercedes-Benz, 6 times for Tesla, and 1 time for Toyota, mainly for upgrading the vehicle system, communication module, motor Control software, etc., allow consumers to complete vehicle recalls without leaving home.

Although OTA remote upgrade represents a higher level of intelligence, it also has certain loopholes. What consumers need to pay attention to is that some car companies use words such as "system upgrade" and "user gift package" to repair vehicles without filing with the regulatory authorities, and fail to resolve the quality of a certain model through the normal recall process. Common problem.

Safety issues such as the spontaneous combustion of the power battery of the new energy vehicle, the failure of the brake, and the failure of the electric drive and electric control have always been the focus of consumers' special attention. Since the beginning of this year, many new energy vehicle companies in the domestic market have recalled vehicles due to potential safety hazards caused by product technical defects.

It is worth noting that with the gradual increase in the number of new energy vehicles, the problems of new energy vehicles not only stay in the power system, battery system and electric drive electronic control, etc., including functional design and assembly quality may become recalled. reason.
