Recently, Autogate.com has successively taken stock of the engine and transmission complaint indexes of joint venture car companies/models and autonomous car companies/models in 2021. In the last issue, we took stock of the luxury brand engine complaint index for everyone. Next, we continue to conduct an annual complaint index analysis of luxury brands/models. In this issue, we talk about the first-class transmission complaint index ranking.
From the above figure, we can see that eight of the top 10 cars in the first-class transmission complaint index are the top three BBA Germans, of which Audi is the leader, and the top three of the complaint index are the Audi series.

It should be pointed out that the BBA's Top Three Germans account for nearly 10% of sales in all vehicle market shares, and the market ownership is very large, which is one of the reasons for the high complaint index of the BBA Ashkenazi Top Three Gearboxes.
