It is necessary to have done at a 4S shop. The advantages of 4S shop maintenance include: 1. More professional maintenance technology; 2. Better service quality; 3. More professional safety performance. Car maintenance, also known as car servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. Car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, and extend the service life. Maintenance items are divided into minor maintenance and major maintenance. Minor maintenance generally refers to the routine maintenance items performed at the manufacturer's specified time or mileage to ensure vehicle performance, mainly including oil and oil filter replacement. Major maintenance refers to the routine maintenance performed at the manufacturer's specified time or mileage, including the replacement of oil, oil filter, air filter, and fuel filter.

I've always thought it's quite necessary to get done at a 4S shop, especially when the car is still under warranty. 4S shops use genuine parts, and their technicians are trained by the manufacturer, ensuring precise alignment with the vehicle's design requirements. Although the prices are higher than those at small roadside shops, in the long run, it avoids rework issues and saves a lot of hassle. For example, with my car, after an oil change at a third-party shop three years ago, it started leaking within a month. It was only at the 4S shop that they identified the issue as an incompatible adapter. The records at 4S shops are also more comprehensive, making it easier to check maintenance history, which benefits resale value later on. Of course, for minor tasks like changing an air filter, doing it yourself is fine, but for critical maintenance like the transmission or brake system, I still trust professionals. Overall, 4S shop services are more reliable and suitable for people like me who prioritize long-term maintenance.

From a cost-saving perspective, dealerships aren't always the first choice, especially for budget-conscious young people. I often get done at chain quick-service shops where prices are lower, potentially saving over half on labor costs. For example, an oil change with three filters can be done for just 200-300 RMB at third-party shops without compromising service quality, as long as you choose certified facilities. However, dealerships have advantages like professional equipment and OEM parts, making them more capable with complex issues such as electronic system failures. For newer models or vehicles with special features, dealership technicians may better understand the required calibrations. My approach is situational: minor jobs go to local garages, major projects to dealerships. This balances cost and quality while allowing me to learn basic maintenance knowledge and avoid overspending.

I think depends on the situation. For simple tasks like changing bulbs or cabin air filters, DIY can save a trip to the dealership and extra costs. However, for complex procedures like engine diagnostics, dealerships have more professional equipment to accurately detect potential issues. They also have access to factory data, avoiding misdiagnosis. From my personal experience, when my car had an oil leak, third-party shops couldn't fix it after several attempts, and the dealership's expertise was ultimately needed. Still, when choosing a service center, consider its reputation and pricing—don't just follow the crowd.

As a family car owner, I insist on getting at 4S shops because safety comes first. If there were issues with brakes or steering while driving with kids, it would be terrifying. 4S shop technicians are experienced and can thoroughly inspect for potential hazards, unlike small repair shops that might occasionally be careless. For example, once when there was an odd smell from the AC, a small repair shop only suggested cleaning, but the 4S shop found a crack in the condenser tube and fixed it in time to avoid poisoning risks. Although it's a bit more expensive, it saves hassle and effort, and regular maintenance extends the vehicle's lifespan. I think this investment is worth it, especially for older cars or those with high mileage—reliable service can prevent major repairs.

In today's era of increasingly intelligent vehicles, servicing at 4S dealerships offers unique advantages. My car is equipped with autonomous driving assistance, and third-party shops may not understand sensor calibration, which requires specialized tools only available at 4S shops. Genuine parts also ensure compatibility, reducing compatibility issues. However, for non-core services like tire rotation, specialized chain stores can save money. Balancing costs, I recommend visiting 4S dealerships during the new car period or warranty coverage, adjusting as needed later. This maximizes cost-effectiveness while ensuring high-tech components like hybrid systems aren't improperly serviced.
