Behind the continuous updating and iteration of the models of the joint venture brand with the development of consumer orientation, it seems to ignore the iteration and improvement of the core component engine, which has led to the continuous "problems" of the engine, and the "frequent occurrence of old diseases" in the new and old models.
In this issue, we will take stock of the engine complaint index of joint venture models.
