I. Overview of complaint data in the second quarter of 2018 According to the data of the domestic leading defective car product information collection platform, in the second quarter of 2018, 16449 cases of effective complaints against auto products were received, a decrease of 21.1% from the previous quarter, and still maintain a high-speed growth trend compared with the same period of last year. In the second quarter of 2017, it rose by 53.8%. According to statistics, this quarter's complaints involved a total of 770 cars belonging to 180 car brands, an increase of 27 brands and 68 cars.

Overall, the complaints in the second quarter presented the following characteristics: 1. The “aftershocks†of the collective complaints in the first quarter were still there. Although the number of complaints related to the issues decreased compared with the first quarter, they remained at a high level. In addition, some models have seen a small number of complaints, and the duration is longer, such as Dongfeng Nissan's "Central Control Screen Death" complaints, FAW-Volkswagen Golf "transmission shocks" complaints. On the one hand, the emergence of such situations reflects the increasing awareness of domestic consumers' rights protection and the broader dimension of rights protection; on the other hand, it also reflects the current demands of some domestic enterprises in the face of consumer product quality and after-sales service. At the time, the attitude and method of settlement have yet to be improved. 2. The volume of complaints in the second quarter remained high growth year-on-year. The number of complaints in the tenth quarter was more than 10,000, of which the number of complaints in April and June exceeded 5,000, but the year-on-year increase was slightly lower than the previous quarter. 3.

(II) Analysis of quarterly changes in complaints As shown in the figure, the car quality network has received more than 10,000 complaints for ten consecutive quarters. The number of quarterly complaints in the past year has shown a step-by-step growth trend. Although the volume of complaints in the second quarter has fallen back, it remains at a high level. (III) Analysis of changes in monthly complaints Specifically, the number of complaints in each month of the second quarter increased significantly year-on-year, but the growth rate was slightly lower than that in the fourth quarter of 2018, with the largest increase in April, up to 78.1%.

(6) Analysis of complaint models The focus of complaints in the second quarter of 2018 was concentrated on SUV models and compact cars, but the number of complaints has dropped significantly from the previous quarter. Affected by the “design defects†and “half-axis oil leakage†problems of GAC Toyota Camry, the volume of complaints of medium-sized vehicles increased by 10.4% in the second quarter. (VII) Analysis of the distribution of complaints In the second quarter of 2018, the complaints received by the vehicle quality network were still mainly concentrated in Guangdong, Jiangsu and Shandong provinces, and the rankings were consistent with the previous quarter. Among them, complaints from Guangdong Province and Shandong Province accounted for an increase in the previous quarter. It is worth noting that “increasing oil†is still one of the top three failures in the three regions. In addition, the number of provinces with more than 1,000 complaints increased during the quarter, and the number of complaints in Henan, Hebei, and Zhejiang provinces exceeded 1,000. The number of complaints in the three provinces was still “the increase in oilâ€.

In the top 20 typical failures in the second quarter, “oil increase†still ranked first, but 1575 complaints dropped significantly by 69.6% from the previous quarter. With the arrival of summer, the "in-vehicle odor" problem reappeared in the top 20 typical failures, and the body rust problem also increased. It is worth mentioning that in the second quarter, Dongfeng Nissan's "Central Control Screen Death" continued to increase. As a result, the number of complaints about "video system failure" increased by 16.3%. (10) Analysis of complaint types of service issues In the second quarter of 2018, the service complaints were classified into one or two other reasons and service attitudes, and the number of related complaints exceeded 1,000. Among them, the “recall plan is unreasonable†among other reasons is still the service issue with the most complaints. After comparing the countries horizontally, it is found that the highest proportion of complaints from other issues is still Japanese brands, accounting for 45.4%, which is much higher than other national brands; the national brands with the highest proportion of service attitude complaints fall into the US brands. It is worth mentioning that in the second quarter, the Korean brand became the national brand with the highest proportion of commitments, such as unfulfilled promises, accessory disputes and service charges, which is intriguing. (11) Analysis of complaint response rate As the leading information collection platform for defective automotive products in China, one of the ultimate goals of the vehicle quality network is to build a channel to coordinate the smooth resolution of disputes between manufacturers and consumers. Therefore, whether the manufacturers take consumer complaints seriously and actively solve them is an indicator that we value very much. In the second quarter of 2018, the number of manufacturers with a complaint response rate of 90% or more was 41, a decrease of 5 from the previous quarter and a decrease of 8 from the same period last year. Among them, there were 23 manufacturers with a complaint response rate of 100%, a decrease of 12 from the previous month and a decrease of 7 from the same period last year. As shown in the above table, the attitude of the listed manufacturers to actively treat consumer appeals and the degree of emphasis are worth encouraging. (12), complaint response satisfaction analysis After receiving the complaint, the manufacturer gives the corresponding solution and responds, representing the degree to which the manufacturer attaches importance to the consumer's appeal. But whether the problem is really resolved, whether the consumer is satisfied with this, the response rate can not directly draw the same number. In the second quarter of 2018, the average score of each brand satisfaction score was 2.7 points, an increase of 0.1 points from the previous quarter. There were 36 satisfaction scores and above, an increase of 6 from the previous quarter. As shown in the above table, the above-mentioned car companies' attitudes and solutions in the second quarter of 2018 have been approved by consumers. Third, the second quarter of 2018 complaints and failure analysis As mentioned above, the quality complaints in the second quarter of 2018, although mainly concentrated in the engine, body accessories and electrical and gearbox systems, but the problem of rust, abnormal steering, and abnormal braking is also worthy of attention. The following is Analysis of more typical complaints this quarter. 1. Engine complaint analysis The data shows that in the second quarter of 2018, the national brand engine failure complaints, although the proportion of independent brands is still the highest, and increased by 6 percentage points compared with the previous quarter. On the other hand, Japanese brands and American brands, the proportion of Japanese brand complaints dropped significantly, down 20% from the previous month; the US brand was just the opposite, with the proportion rising from 9% in the previous quarter to 15%. In the engine failure complaints, the problem of increased engine oil is still ranked first, but the number of related complaints has dropped significantly. As the involved enterprises gradually resolve the problem, the number of complaints will be further reduced. The engine fault light problem reappeared in the TOP5 engine failure, and the related complaints were mainly concentrated in the independent brands and the US and French brands. 2, transmission complaint analysis In the second quarter of 2018, the problem of abnormal noise in the transmission was still the most. Although there was a slight decrease of 5% in the chain, the number of complaints still exceeded 1,000. The problem of the gearbox fault light appeared again in the TOP5 gearbox failure one year later. The relevant complaints were mainly concentrated in Japanese brands and independent brands. In particular, Dongfeng Nissan’s models accounted for most of the complaints, involving the heat of Sylphy and Tiida. Sales models. 3, clutch complaint analysis According to the data of the car network, the complaints of self-owned brand clutches increased by 1 percentage point compared with the previous quarter, which is still much higher than other countries' brands. The relevant complaints are concentrated in some of the self-owned brand hot-selling SUVs, especially the abnormal noise of the clutch. The semi-clutch abnormal noise problem of a US-based joint venture brand manual transmission model reported earlier, the complaints decreased this quarter. Therefore, the proportion of US brand clutch complaints in the second quarter decreased significantly, down 7 percentage points from the previous quarter. From the point of view of complaints, the clutch failure problem has increased by a large margin, up 44.4% from the previous quarter. The complaints are mainly concentrated in the hot models of some independent brands and American brands. 4. Steering system complaint analysis The data shows that the steering system complaints in the second quarter of 2018 are still dominated by abnormal noise, and related complaints remain high. Overall, the number of complaints about the TOP5 faults in the second quarter of the system has declined. The number of complaints about the newly selected steering machine is not high, and the complaints are mainly concentrated in some of the self-owned brands, which are subject to further observation. Subdivided into countries, the proportion of self-owned brand complaints is still significantly ahead of other national brands, but it fell by 3 percentage points from the previous quarter. In contrast, the proportion of legal brands increased by 3 percentage points, and the Korean brand increased by 2 percentage points. 5, brake system complaint analysis In the second quarter of 2018, the problem of abnormal braking was still one of the main complaints of the brake system, and 451 related complaints, down 27.9% from the previous quarter. In addition, the number of complaints about soft brakes and brake failures is still over 100. Among them, more than half of the complaints about soft brakes are concentrated on the Cheetah CS10 model, which has not been properly solved. The ABS fault reappeared in the TOP5 brake complaint, and the number of complaints was nearly one hundred, mainly concentrated in some of the US hot-selling home models. From the perspective of country share, self-owned brands have increased by a large margin, accounting for 9 percentage points higher than the previous quarter, which has exceeded the total of other countries' brands. The same increase is also evident in the US brand, which accounted for a 5 percentage point increase in the previous quarter. 6. Analysis of complaints about front and rear axles and suspension systems In the complaints about the front and rear axles and suspension systems, the problem of abnormal noise of the shock absorbers is still outstanding, but the number of complaints decreased by 388 compared with the previous quarter, and the complaint situation has eased. It is worth noting that in addition to the focus on several self-owned brands selling SUV models, the shock absorber abnormal noise problem has also appeared in some car models. Specific to the country, the proportion of independent brands continued to decline, down 4 percentage points from the previous quarter, but still far surpassed other countries' brands. The number of related complaints remains high, and it can be seen that the suspension problem has become a "common problem" of the self-owned brand models. 7. Analysis of tire complaints In the second quarter of 2018, the number of complaints about tire problems increased, especially the cracking of tires. The related complaints increased by 75.8%. The reason is that Baojun 560 horse brand tire cracking has become the "culprit", and its complaints have surged more than 9 times. From the perspective of the country, the proportion of self-owned brand tires increased to 39%, further opening up the distance with other countries' brands; the Korean brand tire problem increased by 2%, and the complaints were mainly concentrated in a Korean joint venture brand. In the main sales sedan models, the main performance is tire cracking and bulging. 8. Analysis of body accessories and electrical complaints In the second quarter of 2018, the number of complaints about body accessories and electrical appliances decreased, but remained at a high level. The rust problem of the car body is still ranked first in the TOP5 fault, and the number of complaints has risen slightly. The complaints are still mainly concentrated in the self-owned brand models, which is worth pondering. With the advent of summer, the air conditioning problem once again appeared in the TOP5 fault, mainly because the air conditioning is not cooled and the cooling effect is poor. It is worth mentioning that the complaints about audio and video system failures have increased significantly from the previous quarter, up 16.3% from the previous month. The reason for the rise in complaints about audio-visual system failures is that the number of complaints about Dongfeng Nissan’s “Central Control Screen-Crash†problem has increased abnormally in the second quarter. As there are no reasonable solutions for the manufacturers, the number of complaints continues to grow, and it is hoped that relevant enterprises will be able to Pay attention to avoiding the formation of collective complaints.
