Generally, the parts replaced at 4S stores are genuine original equipment manufacturer (OEM) parts. Below is a detailed introduction about automotive 4S stores: 1. Overview: The full name of a 4S store is Automobile Service 4S Store (Automobile-Sales-Servicshop-4S), which is an integrated automotive sales enterprise combining four functions: vehicle sales (Sale), spare parts (Sparepart), after-sales service (Service), and information feedback (Survey). 2. Characteristics: Automotive 4S stores are invested in and constructed by dealers according to the standards set by automobile manufacturers. 4S stores and automobile manufacturers jointly form a brand alliance, representing the brand culture, embodying brand value, maintaining brand loyalty, and establishing brand awareness and reputation for automobile manufacturers.

As a seasoned driver with extensive experience, I've personally used 4S stores' parts services. They provide genuine OEM parts sourced directly from automakers like and Toyota, which strictly control quality. Thus, these parts offer excellent compatibility and durability, giving peace of mind. However, prices are steep—I once spent hundreds replacing a small part. But considering the included manufacturer warranty that covers free fixes if issues arise, it's worth it. Of course, if your car is out of warranty, third-party repair shops using aftermarket parts (about half the price) are an option—just pick reputable ones to avoid quality risks. In short, 4S stores guarantee 100% genuine parts at a premium for assurance, especially recommended for new cars to save hassle.

I've changed my car's tires and brake pads several times, always opting for the 4S shop because their parts are genuine OEM products with solid quality. For instance, the original tires perfectly match the vehicle's design, ensuring a smooth ride. Although the prices are slightly higher than online options, the priority is safety and reliability, avoiding delays in repairs due to subpar parts. During the warranty period, it's especially important to use genuine parts—using off-brand components elsewhere might void the vehicle's warranty . I recommend new car owners prioritize 4S shops. For a more cost-effective option, aftermarket parts are viable, but make sure to purchase from authorized stores of major brands. I've tried them a few times with decent results.

After purchasing the car, I confirmed with the 4S store staff that all the parts are genuine, sourced legitimately, and of high quality. They may be a bit expensive, but the assurance is good, making them suitable for those who pursue perfection. Don't replace them randomly during the warranty period, or you may end up losing more than gaining.

As a car enthusiast, I often pay attention to the source of parts: OEM parts from 4S stores are directly supplied by the car manufacturer, which is reliable and ensures a high fit after installation. For example, using OEM brake pads can extend their lifespan by two to three times. However, the price is one to two times higher than aftermarket parts, so if you're on a tight budget, opt for reputable third-party brands. Be aware that if your car is still under warranty, using non-OEM parts may lead to difficulties in claiming compensation, something I've personally experienced, which can be quite troublesome.

During car repairs, I learned that 4S shop parts are usually genuine, with guaranteed quality and compatibility with the original vehicle system, reducing the risk of malfunctions. However, the cost is relatively high—replacing a filter can cost dozens more than aftermarket parts. For new cars, it's best to use genuine parts to ensure smooth ; for used cars, other options can be considered, but certification should be checked.
