Problem overview

Some Dodge Neon owners report experiencing water leaks into the trunk and back seats, particularly in models from 2000 to 2005. These leaks can lead to significant issues, such as water pooling in the trunk, flooding the back seat, and causing mold and mildew growth, which results in unpleasant odors. The leaks are often attributed to faulty tail light gaskets, allowing water to seep into the trunk area, as well as issues with tail light seals, bolts, and the trunk seal. Prolonged exposure to water can not only create a wet interior but also lead to rust and health hazards due to mold growth, affecting the vehicle's structural integrity. Some owners have successfully mitigated these issues by applying silicone caulking around the tail light assembly, and regular maintenance checks are recommended to prevent leaks. The average repair cost for addressing these water leaks is reported to be around $30. Promptly addressing these concerns is crucial for maintaining the vehicle's condition and safety.
