Toyota Sienna driver's side window weatherstripping issue recurring after replacement on Toyota Sienna

Some Toyota Sienna owners report experiencing recurring issues with the driver's side window weatherstripping, even after replacement. These problems may stem from the quality of the replacement weatherstripping, as using low-quality or incompatible materials can lead to premature wear or detachment. Additionally, improper installation can cause the weatherstripping to come off when the window is rolled down. Environmental factors, such as extreme temperatures and moisture, may further contribute to the degradation of the weatherstripping. Owners are advised to check warranty coverage for recurring issues and consider consulting a professional mechanic for a thorough inspection to identify any underlying problems. Regular maintenance, including cleaning the weatherstripping and avoiding harsh chemicals, is essential for longevity. If the issue persists, it may indicate a more significant problem with the window mechanism or alignment, necessitating further repairs or adjustments.
