The service life of car sunshades typically ranges from 5 to 10 years, depending on the material, usage environment, and maintenance method. Sunshades made of aluminum foil composite material offer the best durability, lasting over 8 years, while those made of fabric or PVC may show signs of aging after 3 to 7 years. Prolonged exposure to outdoor sunlight and high temperatures accelerates material fading and embrittlement. In particular, mechanical components of electric sunshades (such as guide rails and springs) may become stuck or detached due to frequent operation or insufficient lubrication. It is recommended to regularly clean dust from the sunshade surface, avoid rough handling, and check the lubrication of the tracks. If the sunshade operates unevenly or the fasteners become loose, prompt repairs are necessary to prevent glass scratches or PVB interlayer degradation. Replacing a panoramic sunroof sunshade costs approximately 150 to 300 ringgit and requires professional headliner removal for installation. Proper use and maintenance can significantly enhance the sunshade's UV protection and extend its service life.
