1. Damaged Weather Stripping: The weather stripping around the trunk lid can become worn out or damaged over time, allowing water to seep into the trunk.
2. Clogged Drain Holes: There are drain holes in the bottom of the trunk to allow water to escape. If these holes become clogged, water can back up and leak into the trunk.
3. Faulty Tail Light Gaskets: The gaskets around the tail lights can also become damaged or loose, allowing water to leak into the trunk.
4. Damaged Trunk Lid: If the trunk lid itself is damaged, it may not seal properly and allow water to leak in.
5. Rust: Rust around the trunk lid or the trunk floor can create gaps that allow water to seep in.
6. Cracked or Broken Plastic Rivets: Some Buick Park Avenue models use plastic rivets to attach the weatherstripping around the trunk lid. Over time, these rivets can crack or break, allowing water to leak into the trunk.
If your Buick Park Avenue is experiencing a trunk leak, it is recommended to have it inspected by a qualified mechanic or automotive technician.
