According to the national automobile production and sales data provided by the China Association of Automobile Manufacturers, the cumulative retail sales of the domestic sedan market in March 2023 were 759000 units, an increase of 15.7% month on month and a slight decrease of 0.8% year on year. During the same period, Car Quality Network received a total of 6369 valid complaints from car owners regarding sedans, an increase of 17.7% month on month and 31.2% year on year.

　　In March, among the quality issues of sedans, the "audio and video system malfunction" made a comeback, with a month on month increase of 82.6% in complaint volume, ranking first among the malfunction issues again. And the number of complaints about "dashboard cracking" also showed a significant increase month on month, with the number of complaints exceeding 600. It is worth noting that the number of complaints about "seat malfunctions" has doubled, with the increase concentrated in some domestic brand new energy vehicles. In terms of service issues, "not in line with publicity" returned to the top, with a month on month increase of about 1.2 times. In addition, the "system upgrade issue" has also experienced a doubling of the month on month growth, with most of the increase in complaints concentrated in some domestic brand models. After removing the information that the complainant voluntarily applied for withdrawal, the ranking of the top 30 sedan sales complaints in March 2023 is as follows:

　　Data Focus:

　　1. Successfully topped sales, BYD Dolphin entered the fast lane of development

　　After a wave of "two consecutive increases" in sales, BYD Dolphin finally ushered in a shining moment, with sales in March setting a new monthly sales record. According to data from the China Association of Automobile Manufacturers, from January to March this year, the cumulative sales of Dolphins reached 67951 units, a doubling growth compared to the same period last year, ranking among the top in the domestic new energy market sales list. Looking back at its sales changes over the past year, it has shown a stable upward trend overall. In the second half of 2022, it achieved six consecutive months of sales exceeding 20000 units, becoming another important sales pillar in BYD's sedan camp after Qin PLUS. Looking back at its monthly complaint performance in the past year, except for the abnormal changes in the second and third quarters of 2022, the number of dolphin complaints has been decreasing month by month since October 2022. The number of complaints in March has dropped to single digits, and the short-term reputation performance shows signs of improvement. With the new models launched at the end of 2022 entering the market, Dolphin's product strength has been strengthened, and future market performance is expected to continue to rise.

　　2. Generation bonus support for Accord is expected to achieve self breakthrough

　　As the leading player of GAC Honda, the sales of the Accord began to rebound in March, returning to the "20000 car club". From its monthly sales trend in the past year, it can be seen that after reaching its peak in 2022, the overall monthly sales of Accord have shown a downward trend. There were two turning points in sales during this period, one in December 2022 and the other in March of this year, which ended the recent "two consecutive declines" in sales and achieved a significant rebound. In contrast, the monthly complaint volume trend of Accord in the past year has been relatively stable, outperforming its old rivals GAC Toyota Camry and Dongfeng Nissan Teana, and its short-term reputation performance is worthy of recognition. Recently, it was reported that after five years, the 11th generation Accord will officially make its debut at the Shanghai Auto Show this month. Under the stimulation of the upcoming model upgrade, the monthly sales of the Accord are expected to continue to recover in the short term, and it may not be difficult to reach new highs.

　　3. Steady and steady victory for Audi A6L

　　After experiencing a peak in sales in August 2022, the sales of the Audi A6L began to decline, but there was a slight recovery after entering 2023. In March, the monthly sales of Audi A6L achieved its best performance in nearly six months after achieving four consecutive months of month on month growth. According to data from the China Association of Automobile Manufacturers, the cumulative sales of the Audi A6L in the first three months of this year were 39154 units, an increase of 52.4% compared to the same period last year, significantly leading the BMW 5 Series and Mercedes Benz E-Class, achieving a phased victory in the BBA sales competition. Similar to the sales trend, the number of complaints from the Audi A6L has recently increased month by month, but overall it is still within a normal range, with a better short-term reputation than BMW 5 Series and Mercedes Benz E-Class. In the short term, as the mid-term facelift continues to be launched on the market, the sales of the Audi A6L are expected to continue to rise. It is expected that we can maintain our current leading edge in the BBA sales competition in the future.

　　4. Sales continue to rebound, Changan Lumin maintains a "dark horse" posture

　　After entering 2023, the monthly sales of Changan Lumin have rebounded continuously, with sales returning to over 10000 vehicles in March. As a rising star in micro cars, Changan Lumin has been favored by many young consumers with its cute appearance, rich color schemes, and high-tech interior design, and its market performance has also skyrocketed. Despite experiencing a decline in sales in early 2023, the cumulative sales from January to March this year still hold a leading position in the micro car pure electric vehicle market, second only to the Wuling Hongguang MINIEV. It is worth mentioning that the monthly complaint volume of Changan Lumin in the past year has always remained in single digits, and its short-term reputation performance is commendable. However, in terms of the current micro pure electric vehicle market, with the continuous influx of new products and intensifying competition, the recently launched Geely Panda Mini may become the biggest competitor of Changan Lumin. So for Changan Lumin, how to ensure the frequency of product iteration updates and maintain market freshness will become the focus of the next stage of work
