What is the situation when the production dates of the glass on a new car are inconsistent?

[DelWalker]

It is normal for the production dates of the glass on a new car to be inconsistent. The glass is assembled by the car manufacturer, and the assembly time depends on when the glass is delivered by the glass factory. The glass on a single car may be delivered by the glass factory at different times. If there is a quality issue with the glass, the inconsistent production dates can serve as valid evidence of the glass quality. Methods to determine whether the car glass has been replaced: 1. Check the glass label—original factory glass labels have the car brand logo and the glass brand logo; 2. Check the production date—normally, the production dates of all the glass on the car should be close to the vehicle's production date; 3. Check the manufacturer—by reviewing the manufacturer code on the glass, you can identify which company produced the glass; 4. Inspect the appearance—determine whether the glass has been replaced by observing the glass and its surrounding appearance.
