What Causes the Door Rattle in a Corolla Hybrid While Driving?

[ElisaLee]

Door rattle can be caused by aging door seal strips, loose door glass, loose screws in the window regulator, or insufficient tightness between the door lock post and the door lock. Below are the detailed reasons for door rattling: 1. Repeated opening and closing of the door can lead to aging of the door seal strips. Over time, this can cause deformation during operation, resulting in noise. Therefore, when opening and closing doors in daily use, it's essential to pay attention to the force applied and to maintain the door seal strips properly. Regular cleaning and inspection can help slow down the aging process of the strips; 2. Insufficient tightness between the door lock post and the door lock. This can create a significant gap between the lock post and the lock after the door is closed. Such a gap can cause considerable noise during vibrations. The solution is to adjust the position of the lock post to ensure a tight fit with the door lock. Eliminating the gap will naturally prevent vibration-related noises.
