Chrysler 300 moon roof leaking during heavy rain, suspected frame sealing issue on Chrysler 300

Some Chrysler 300 owners report experiencing moon roof leakage during heavy rain, often attributed to problems with the frame sealing. These owners have noted patterns of water seeping through the passenger side roof, with leakage increasing over time. Despite attempts to clear drain tubes, fix frame gaps, and even replace the panoramic roof frame, the issue has persisted for some. The leaks tend to occur only during heavy rain and are often localized, particularly at the passenger side rear of the vehicle. Proper maintenance is crucial, as debris buildup around the moon roof can create water dams, exacerbating the problem during heavy rains. To address these concerns, it is recommended that owners seek a professional inspection of the moon roof frame and sealing, and consider necessary repairs or replacements to ensure effective sealing. Regular maintenance of the moon roof and surrounding areas is also advised to prevent future leaks.
