Chevrolet Impala trunk leak issue due to tail light seals on Chevrolet Impala

Some Chevrolet Impala owners report experiencing trunk leaks due to faulty tail light seals, particularly in the 2014 model year. This issue can lead to water entering the trunk area, resulting in potential damage and unpleasant odors. Owners have noted finding water in the trunk well, especially after needing access to the spare tire following incidents like a blown tire. Repairs often involve replacing the tail lamp gaskets and inspecting for any water damage or odors. In some cases, the leak may originate around the rear tail-lights in the body seam, making it challenging to identify. To diagnose the source of the leak, it is recommended to thoroughly clean the trunk and run water over the rear window and trunk lid. Replacing the gaskets with the correct OEM parts can help resolve the issue. It is advisable for owners experiencing this problem to have the tail light seals inspected and replaced as needed to prevent further complications.
