With the rapid growth of private car ownership, complaints about car maintenance are also gradually increasing. I have learned from relevant sources that there are indeed many "tricks" behind car maintenance.
In cases of maintenance complaints, the situation of shoddy goods being the most serious. According to relevant sources, most methods involve replacing the original factory's parts with a secondary factory, but they also charge the price of the original factory. For example, the problem of substandard filters, clutch accessories, and brake pads in cars is the most common. The use of these counterfeit spare parts can cause damage to the car's early machinery, and in severe cases, may result in some parts being scrapped. In other cases, car parts manufacturers have strict control, and in some roadside repair shops, they replace them with different brands of parts. This situation has also occurred in many cases.
A car has tens of thousands of components, and currently, each model of car in the market generally has several types of spare parts, including loading parts, original factory parts, manufacturer specified parts, market matching parts, and "three no" non parts. Therefore, due to differences in component quality and manufacturers, prices often vary several times. So, often the maintenance market is quite chaotic, with products such as automotive clutch parts and brake system components not clearly priced, and market prices being chaotic, making it an opportunity for some unscrupulous vendors to take advantage.
