How long is the warranty for car window tinting at 4S stores?
2 Answers
Currently, the general warranty period for car window tinting is five years. Under normal circumstances, as long as genuine film is used and the vehicle is operated properly after installation, the film will not bubble no matter how many years pass. The color of the film may fade after six years, which is normal, but it will definitely not bubble. Here are some precautions to note: 1. Do not open or close the car windows: Avoid operating the windows for one week after the film is applied, and extend this period appropriately in winter. 2. Avoid using rear window heating for one week: Do not use it for half a month in winter. Otherwise, issues like bubbling and wrinkling may occur. 3. Do not apply the film on rainy days: Check the weather forecast for the next few days before applying the film, and avoid applying it during continuous rainy weather.
When I got my car window film at the 4S store, the staff mentioned warranties typically last 5 to 10 years, depending on the film's brand and grade. Premium films can even offer 10-year or lifetime warranties. I recommend keeping the warranty card after installation—it usually covers manufacturing issues like bubbling, fading, or peeling, but not scratches caused by human error. Maintenance is simple: avoid ammonia-based cleaners and use a soft cloth when washing. My film still looks new after three years. A longer warranty saves hassle and money, especially with its great heat-blocking effect in summer.
