Is the glass replacement at a 4S shop the same as the original?

The glass replaced at a 4S shop should be the same as the original. Precautions for car repairs at 4S shops: 1. Agree on the price before repair: 4S shops do not negotiate prices, while other repair shops may allow bargaining. Before the repair, clarify the parts to be repaired, the components to be used, labor costs, and the total amount to avoid unexpected "additional charges" during the process. 2. Carefully inspect and verify the vehicle's exterior damage: Before the repair, check the vehicle's exterior with the repair shop to identify any dents or scratches to prevent "accidental damage" by workers during the repair. 3. Try to supervise the repair process: If you watch the repair, the workers may be more diligent, reducing minor damages to the car.
Last year, I had my windshield replaced at a 4S dealership, and it felt just like the original. They used genuine OEM glass parts, sourced directly from the car manufacturer, so the material and dimensions matched perfectly. The installation process was also very professional—the technician followed the standard procedure: first cleaning off the old adhesive, then applying new sealant, and using specialized equipment to press and bond it, preventing leaks or noise. The key advantage is that 4S dealerships have manufacturer certification, so if any issues arise, like glass wobbling or cracks, you can immediately claim the warranty. Of course, installation quality depends on the technician’s experience—some 4S shops work quickly but not meticulously, so it’s best to choose a reputable one. Overall, getting your windshield replaced at a 4S dealership is more reliable than at small shops, since genuine parts are paired with the original car, reducing future problems. However, it’s more expensive—whether it’s worth it depends on your budget.
Speaking of windshield replacement, I've tried it a few times at the 4S shop, and the overall results were decent. The glass itself is the same as the original factory part, with matching part numbers, and after installation, it looks as good as new. But their installation technique matters a lot: a skilled technician will thoroughly clean the window frame, apply the sealant evenly, and use an oven to cure it properly, ensuring a secure bond to avoid wind noise during rain or high-speed driving. Occasionally, a less experienced worker might overlook gaps in the sealant, leading to minor leaks. I believe the advantage of 4S shops lies in their after-sales service, such as offering a one-year warranty on the glass—if there's an issue, you can just take it back for repairs. The price might be slightly higher, but it's better than randomly choosing a roadside shop, especially since the windshield affects both safety and noise insulation. After the replacement, the driving experience feels no different, so I recommend discussing installation details with the shop beforehand.
