Generally not. Repair shops have limited spare parts, and if they remove components from the car, they can't replace them. Additionally, for new cars, any removed or replaced parts are easily noticeable, so you can rest assured during repairs without worry. Moreover, it would be time-consuming and labor-intensive for workshop staff to engage in such acts of stealing parts, and even if they did, the parts wouldn't fetch a high price. Precautions: Check items: Before leaving the vehicle, always check the items inside. If anything is missing, immediately inquire with the repair personnel to quickly recover them. Otherwise, once the car is driven away, it may be difficult to identify missing items later. Inspect for scratches: When picking up the car, check the exterior for any scratches, as during maintenance, workers might accidentally damage the car's paint. Additionally, before taking the car away, ensure all relevant repair procedures are completed, otherwise many shop owners might default. For example, whether payment has been made, invoices received, etc.

As a frequent car buyer, I understand your concerns. There's always that worry about dealerships tampering with new cars, but experience tells me most reputable 4S stores wouldn't dare to casually replace components like seats or navigation systems - their brand reputation is too valuable. Getting caught would mean losing customer trust and potentially facing legal consequences. When I purchase a vehicle, I always take time to meticulously inspect details: checking if the mileage is low, verifying all electronic features work properly, and looking for signs of wear on interior components. This basic verification helps ensure factory condition. Should you encounter malpractice, warranty protections allow you to file complaints. Remember, buying a car is a major decision - choosing an established dealership with good reputation reduces risks. New vehicles come with detailed factory records, making it prohibitively expensive for dealership staff to tamper with components. While vigilance is wise, excessive anxiety isn't necessary.

From the perspective of chatting with my technician friend, I've heard that cases of new car parts being secretly swapped out are extremely rare. The main revenue sources for 4S shops are sales and subsequent maintenance services. If they tamper with new car components like audio systems or tires, it's easy for customers to file complaints and trace evidence, leading to fines. New cars from the factory are well-sealed, and any modifications require professional tools and incur high time costs. As a buyer, I would check the vehicle's production date to ensure it's recent and verify that all internal configurations match the contract before taking delivery. Visiting multiple shops for comparison can also reveal discrepancies. Maintaining personal records, such as taking photos as evidence, is a good idea. Most 4S shop employees are trained and wouldn't engage in such foolish behavior, as long-term business relies on maintaining a good reputation.

Considering the overall norms of the automotive industry, I've observed the operational models of some 4S dealerships. They must adhere to the manufacturer's standardized procedures, making it nearly impossible to replace new car parts such as air conditioning or lighting systems. This would violate the warranty agreement, and if a customer complains, the 4S store would have to repair it for free and possibly compensate. Legally, this constitutes fraudulent behavior with high risks and low profits, so reputable stores wouldn't take the risk. However, there have indeed been a few small shops with chaotic management that encountered issues, which is why it's important to check their history and online reviews when choosing a store. Testing all functions on the spot and verifying the checklist when purchasing a car are effective preventive measures. Don't just focus on the exterior details; opening the car door to inspect the internal component labels can provide additional peace of mind.
