What is the normal difference in production dates for new car glass?
2 Answers
New car glass with a production date difference of 2-3 months is considered normal. Below are specific methods to check whether the glass has been replaced: 1. Manufacturer: The manufacturer code on the glass can indicate which company produced the glass. Generally, car manufacturers purchase glass in bulk and do not use too many brands or the same brand from different production locations. 2. Glass production date: If there is a significant difference in the production dates of each piece of glass on a car, it may indicate that the car has been refurbished or the glass was replaced later. 3. Glass label: If the car glass has been replaced, the new glass label will be noticeably different from the original factory label.
When I first bought a car, I was also curious about the difference in glass dates. Normally, the production dates of glass on a new car shouldn’t differ by more than six months. For example, if the windshield was produced in March and the side windows in August, that’s fine because the car factory needs time for assembly. A friend of mine who worked at an auto plant said it’s common for glass to come from different production batches—as long as the date codes are close to the car’s manufacturing time, it’s no issue. However, if the dates differ by a year or more, you should be wary, as the glass might have been replaced due to an accident. Before taking delivery, remember to check the date codes in the corners of each glass panel—use a small flashlight to see the numbers and dots indicating the year and month. Don’t just rely on the salesperson’s pitch; inspecting it yourself can help you avoid pitfalls. If you find anything unusual, raise the issue immediately and demand a replacement car or compensation—this way, you can enjoy your new car with peace of mind.
