Who is responsible for performing the secondary maintenance of a vehicle?

Secondary maintenance is a vehicle maintenance operation performed by maintenance enterprises. In addition to the primary maintenance tasks, it mainly involves inspecting and adjusting safety components that are prone to wear or deformation after a certain period of use, such as steering knuckles, steering rocker arms, brake shoes, and suspensions, as well as disassembling and inspecting tires for rotation. The mileage intervals for secondary maintenance vary among different brands and models, and should be determined based on the maintenance manual of the specific vehicle. The main contents include the following aspects: 1. Engine section: Inspect cylinder pressure or vacuum, and check for oil leaks in oil seals and the rear bearing of the crankshaft. 2. Clutch and transmission section: Check the effectiveness of the clutch and the bolts of the bottom cover, adjust the free travel of the pedal, and apply grease to the pedal shaft.
The secondary maintenance work is usually handled by professional technicians at repair shops. I typically drive my car in for a check-up every 5,000 to 10,000 kilometers. They thoroughly inspect the brake pads, tire pressure, oil condition, and minor details like loose chassis screws. If skipped, the car might break down unexpectedly—like the time I neglected a maintenance session and ended up with terrifying brake failure on the highway. Technicians use professional tools to test the drivetrain and electronic systems, while car owners only need to book an appointment and pay the fee. Authorized repair centers or 4S shops are qualified to perform these tasks, so choosing a reliable place is crucial—don’t cut corners with small workshops. In short, stick to the manual’s recommended maintenance schedule to save on hefty repair costs and ensure safety.
The responsibility for secondary vehicle maintenance falls on the certified technicians of the repair shop, who follow rigorous procedures such as measuring brake wear and checking engine performance. Technicians use diagnostic equipment to identify potential issues, replacing worn parts when necessary to ensure the vehicle meets roadworthiness standards. Owners must bring their vehicles in on time to cooperate with the process. From my experience, delayed maintenance can lead to increased repair costs due to transmission system failures. The maintenance team strictly adheres to regulations, with chassis adjustments and electrical tests being key focuses. Choosing a certified service center is crucial to avoid improper handling that could lead to subsequent risks. Regular maintenance can extend a car's lifespan, making the investment in professional services well worth it.
