In recent years, the domestic automobile industry has witnessed rapid growth. However, concerns have arisen regarding the overall durability of these vehicles. Some bloggers have highlighted a prevalent issue among domestic automakers: they seem to be advancing at a breakneck pace, with durability and design standards struggling to keep up. In essence, there's a lack of thorough DFMEA (Design Failure Mode and Effects Analysis) and PFMEA (Process Failure Mode and Effects Analysis) practices.
Back in the early days, domestic cars faced several shortcomings in terms of material quality, production techniques, and quality control. For instance, the use of low-strength alloy materials led to swift wheel degradation. Subpar painting methods resulted in car paint that was prone to peeling and rusting. Moreover, there were significant issues with the manufacturing processes and quality assurance of transmissions.
Yet, with technological progress and strategic market adjustments, domestic vehicles have made remarkable strides in enhancing durability. This includes the adoption of higher-strength materials, refined painting techniques, and improved low-temperature performance of electronic systems. Despite these advancements, there's still ample room for improvement, particularly in the meticulous control of assembly process details for domestic vehicles.
