In 2021, China’s passenger vehicle retail sales totaled 20.146 million units, up 4.4% year-on-year.It is worth mentioning that the domestic new energy passenger car market has always maintained a high growth trend under the environment of lack of core and repeated epidemic.In 2021, the domestic retail volume of new energy passenger vehicles was 2.989 million units, up 169.1% year on year, and the market penetration rate was 14.8%.It can be seen that the trend of new energy vehicles and traditional fuel vehicles forms a strong difference in the characteristics, to achieve the partial substitution effect of new energy vehicles on the fuel vehicle market.Accelerate the car market to new energy transformation.The growth of the overall car market has been accompanied by an increase in car-related complaints.A total of 27,018 complaints were filed in 2021, up 11.4 percent year on year, according to statistics from the Automobile Complaints Website.In addition, from the monthly statistics, the main increase in complaints or concentrated in the second half of the year.On the one hand, the overall car market tends to be stable in the second half of the year, which is conducive to sales.On the other hand, explore yue particles capture device and euler chip collective complaints.In numerous complaints, mainly related to product quality, sales disputes, after-sales service, etc.In a breakdown, 12,602 complaints related to power systems were filed, a significant increase compared with 2020.Power interruption has become one of the more prominent problems, involving the relevant brand models of Skoda, Roewe, and BAIC new Energy and so on, covering traditional fuel vehicles and pure electric vehicles.Among them, EU/EV series of BAIC new energy is the most typical.Vehicle spontaneous combustion, power suddenly disappear, battery life serious attenuation, vehicle charging failure, etc., an endless variety of patterns of failure to make users extremely upset.At the same time, it also brings security risks to their own cars and daily travel.According to the owner of the car involved, the power of the vehicle was suddenly interrupted while driving, and the cause of the disease was not eliminated after repair in the shop. The longest repair time was as long as 10 months.Another owner also said that its purchase of EX360 power battery failure, the same is in the after-sales hit a wall, parked in the maintenance station for more than 20 days to no one.It can be seen that, in addition to the hidden dangers of product quality, BaiC new energy in the after-sales treatment, there are also “old difficulties”.In addition, according to the Defective Product Management Center of the State Administration for Market Regulation, BAIC New Energy recalled a total of 31,963 EX360 and EU400 models produced from November 1, 2016 to December 21, 2018, starting from March 24, 2021.However, the EU/EV series of powertrain failure complaints, which appeared in “piles”, did not appear in the recall announcement, and the fault is indisputable fact.It is worth noting that the recall was carried out under the launch of the defect investigation by the State Administration for Market Regulation, rather than the recall plan filed by the State Administration for Market Regulation after the defect was found.In contrast, because of the CVT main line bundle terminal protection problem and lead to the vehicle may appear power interruption of the scene 580, this can take the initiative to recall the public, face the problem of dongfeng well-off enterprises, will be more responsible, but also reflects the sense of responsibility to consumers.In addition, the GENERAL Administration of Quality Supervision, Inspection and Quarantine also found that Dongfeng Nissan Qichen recalled part of 2021 Qichen D60EV and T60EV electric vehicles produced from May 8, 2021 to July 20, 2021, a total of 1,136 vehicles.Due to the insufficient welding strength of the relay components of the high-voltage distribution box in the power battery pack, the welding part of the relay will break during the driving process of the vehicle, resulting in power interruption of the vehicle and hidden safety risks.The analysis of the site’s raw data shows that power outages are a major factor in the increase in the number of powertrain complaints about quality problems.At the same time, many of them are involved in collective problems, but also shows that the product quality does exist in some aspects of defects or hidden dangers.In the face of a large number of complaints, different enterprises have also produced different ways to deal with them, including taking the initiative to attack, seeing and dismantling, and turning a blind eye.I believe we all know which way is more appropriate.Although recall system is now a line of defense, as an enterprise, it is still necessary to actively strengthen the collection and monitoring of defect clues.
