Honda Civic del Sol trunk leak issue despite silicone sealant around taillights on Honda Civic del Sol

Some Honda Civic del Sol owners report experiencing trunk leaks even after applying silicone sealant around the taillights. These leaks may be caused by a damaged or worn trunk seal, allowing water to seep in. Additionally, faulty seals on the rear sail panels can lead to water accumulation or musty odors in the trunk area. Cracks in the window seal may also contribute to leaks down the c-pillars, necessitating a thorough leak test to identify any hidden issues. Furthermore, a faulty seal around the radio antenna base can be another source of water intrusion. Owners should also check for water accumulation below the interior lining or within the wall quarter panels, which could indicate drainage or vent blockages. Addressing these potential sources in conjunction with the silicone sealant can help effectively resolve trunk leak issues.
