What are the effects of replacing the windshield at a 4S store?
2 Answers
4S stores use original factory-shipped glass, which are all vehicle-mounted parts. There are no negative effects. Here are some precautions to note after windshield replacement: 1. Avoid washing the car for three days: To prevent wind and water leaks, do not wash the car for three days, and remove the tape securing the windshield position after three days. 2. Drive smoothly: Maintain steady driving and avoid sudden braking or rapid acceleration. 3. Avoid excessively bumpy roads: Try to avoid roads with too many bumps to prevent the windshield from shifting. 4. Control speed: Keep the maximum speed below 80 km/h and avoid high-speed driving.
The most obvious feeling about replacing the windshield at a 4S shop is that it's worry-free but costs more. I had mine replaced after it was cracked by a stone. Their glass is 100% original factory parts, exactly the same as when it left the factory, with no optical distortion or thickness deviation. During installation, I saw the technician using a professional positioning bracket to secure it, and the adhesive used was original factory sealant, unlike roadside shops that just slap it on carelessly. However, the bill was indeed about 30% more expensive than at a repair shop, and you often have to wait in line for parts. After replacement, you also need to be careful not to wash the car or drive on the highway for three days to let the adhesive fully cure. It's been over two years now, with no leaks or strange noises. Once, they even fixed a small crack at the edge of the glass for free, so the higher cost is somewhat justified by the peace of mind.
