For a car with 70,000 kilometers, the following maintenance should be performed: 1. Consider replacing the tires. When a car reaches over 70,000 kilometers, the tire tread is usually severely worn, and the rubber may have aged. For driving safety, it is recommended to replace the tires. 2. Replace the transmission fluid. Transmission fluid has a usage cycle and generally needs to be replaced every 2 years or 40,000 kilometers. 3. Clean the three-way catalytic converter. As the vehicle's mileage increases, carbon deposits from the engine can clog the three-way catalytic converter, leading to poor acceleration and failing emission standards. The cleaning cycle for the three-way catalytic converter is typically every 30,000 to 40,000 kilometers. It is recommended to clean it at this point. 4. Inspect the vehicle's suspension and various rubber bushings. These rubber bushings play a role in supporting and stabilizing the vehicle's engine. Over time, rubber aging can cause various noises from the chassis while driving. Therefore, it is recommended to inspect the suspension system.

Do All Cars Need Chips?

Only purely mechanical vehicles produced in the early stages do not require chips, while modern cars do need them. Extended information: The automotive chip shortage is primarily caused by multiple factors including pandemic-related shutdowns of upstream chip manufacturers, strikes at STMicroelectronics, and halted production at Southeast Asian chip assembly plants, leading to severe semiconductor shortages in the global market. Among these, the Electronic Stability Program (ESP) and the intelligent Engine Control Unit (ECO) are the two modules most affected by the automotive chip shortage. Suppliers: Currently, the main suppliers for domestic automakers are Continental AG and Bosch. Both ESP and ECO are considered 'standard equipment' in many high-end vehicle models, and numerous automakers have been impacted by the chip supply disruption.
