AutoBeta(AutoBeta.net)01/31 Report--

According to retail data released by the Federation of passengers, there are 2.989 million new energy passenger vehicles in China in 2021, an increase of 169.1% over the same period last year. Among them, the number of new energy passenger vehicles in December 2021 was 475000, an increase of 128.9 percent over the same period last year and 25.5 percent month-on-month. From the data, it is not difficult to see that even affected by the epidemic and chip shortage, new energy vehicles still shine during the year and achieved good results. However, in the context of the rapid growth of sales, the quality problems of new energy vehicles are also emerging, especially pure electric vehicles. To this end, based on the data of the third-party automobile complaint website, the automobile industry focused on the ranking of the top ten pure electric vehicle complaints in the past year.

According to the overall ranking, the Great Wall Ora good cat ranks first in the list of complaints with a total of 1569 complaints, leading a group of models on the list because of "sales fraud and publicity discrepancies." From the list, in addition to Ola good cat, most of the other models on the list are also independent models, such as Mercedes-Benz E-Star in second place, Geely Geometry EX3 Kung Fu Niu in third place, BYD Han in fourth place, Guangzhou Automotive Aion S in fifth place, and most of these models are also hot models in the market.

You must have heard a little about what happened to the Euler cat in 2021. In early November 2021, Ola Hao Cat received a large number of complaints from car owners for "secretly changing chips", which became more and more intense and was finally named by CCTV. About the course of the incident, after the owner of the Euler cat picked up the car, he accidentally found that the chip information displayed in the system information did not match the chip model claimed by Euler Automobile official Euler. In the official promotional materials of Euler Automobile, it is claimed that the Euler cat uses Qualcomm 8-core CPU chip, but the vehicle information shows that it is equipped with Intel 4-core chip. The incident triggered a large number of complaints from car owners after it was exposed online, and CCTV's financial channel also conducted a special investigation report. Finally, Euler Automobile introduced a compensation plan, promising to give car owners 10000 yuan in charging rights to be paid out in cash, the bustling Ola good cat chip fraud came to an end. Of course, there are car owners who do not approve of this compensation scheme, or will use legal means to solve the problem. For now, however, there has been a marked decline in complaints from Olla cats, and its sales continue to grow even in the context of a high number of complaints. According to the data, the cumulative sales of Euler good cats were 49900 in 2021 and about 2000 in the first half of 2021, but sales began to grow sharply in the second half of the year and exceeded 10,000 for the first time in December.

As a miniature electric vehicle owned by Changan New Energy, the Mercedes-Benz E-Star was also involved in product controversy in 2021. According to data from the quality website, due to problems such as disguised charges, failure to pick up cars, lack of mileage and power battery failures, Ben E-Star filed a total of 382 complaints in 2021, which is far less than Euler cats, but it is also ahead of many pure electric vehicles. According to previous reports concerned by the auto industry, also in November 2021, a notice on stopping taking orders for Mercedes-Benz E-Star and CS55 E-Rock cars was circulated online, which showed that after a study by Changan New Energy Marketing Service Center, it was decided to suspend the collection of orders for Mercedes-Benz E-Star and CS55 E-Rock cars. However, behind the circulation of the document. According to Changan's official website, only the latest and most expensive colorful models in the national version of the Mercedes-Benz E-Star can continue to be booked, while Xinxin, Xinyi and Xinyue versions of the three low-end old models are all stopped. To this end, many prospective owners of the Chang'an Mercedes-Benz E-Star gave feedback in the circle of friends, but they could not pick up the car for many months. even if the car arrived, they were asked to increase the price by 5000 yuan to buy a service package. if they did not buy it, they would continue to wait for the car and give it to the next one who could accept the purchase of the service package. On December 4, Changan New Energy issued the notice on further strengthening the communication and delivery of orders for the received Mercedes-Benz E-Star, which explicitly responded that the cash Mercedes-Benz E-Star has not stopped production and stopped accepting current model orders in order to avoid longer delivery waiting time.

Other autonomous models, such as the Weima EX5, are also in the top 10 of the annual pure electric complaint list, which is the only new car-building product. In the new power products, Weima EX5's product performance is not strong, but it has repeatedly attracted the attention of the industry because of quality problems. For example, there were several fires in just a few days in December 2021. In addition, what puzzles car owners even more is that Weima EX5 is exposed to be "power-locked". After upgrading the system, the mileage of Weima EX5 has been significantly reduced. For example, the same road conditions and driving environment could have driven 350km, but only less than 260km after upgrading the system. Learned from the car quality website, such complaints are not rare, which means that this is not the only one.

In addition to the above two models, such as the BMW iX3 has also been complained by car owners. It is understood that on November 17, 2021, brilliance BMW issued a notice of "technology upgrade" service activities to car owners through the official App, which informed the relevant owners that BMW found that "the vehicle's high-voltage battery unit module may be faulty" in the process of quality analysis, requiring customers to go to the dealer for battery disassembly and battery module replacement.

According to the official statement, vehicles involved in this problem will add a fault record, the vehicle will lose power when the high-voltage system is turned off, and the vehicle will glide slowly until it stops, which means that in serious cases, it may cause the vehicle to lose power and cause a traffic accident. BMW manufacturers require the relevant vehicles to go to the 4S store to disassemble the entire power battery pack and replace the defective battery modules in 10 sets of battery modules.

However, in the view of many car owners, BMW manufacturers should recall their products but call it "technology upgrade", which can not be accepted and recognized by car owners. Finally, with the expansion of market public opinion, brilliance BMW formally filed a recall plan with the regulatory authorities on December 24, 2021, recalling 1974 domestic iX3 from April 30, 2021 to August 27, 2021, to replace free power battery modules with welding defects for vehicles within the scope of the recall. It is understood that the recall solution is consistent with the previous technology upgrade plan issued by brilliance BMW, although the solution is the same, but the brilliance BMW should adopt the way of technology upgrade to express disapproval of the manufacturer's practice.

Judging from the data, the rapid growth of new energy vehicle sales reflects the recognition of the market to a certain extent, but the increase in the number of complaints also means that the products are worrying. Of course, the automotive industry has always believed that recognizing mistakes is the beginning of improvement, and that the root of consumer complaints is to solve the problem. As long as car companies can solve the problem properly, this is actually one of the ways to promote brands and products. On the contrary, denying that there is a real problem may make the result worse and may even pay a heavier price.
