Water leaks in trunk when it rains 2004 ION?

Water leaks in the trunk of a 2004 Saturn ION can be caused by several factors, including clogged drainage channels, worn weather stripping, or damaged seals around the trunk lid. Check for debris in the drainage areas and inspect the rubber seals for cracks or deterioration. Additionally, ensure that the tail light assemblies are properly sealed, as leaks can occur there as well. If the problem persists, consider consulting a professional for a thorough inspection.
