What Causes a Mazda 5 Hatch Leak?

There are several potential causes of a hatch leak in a Mazda 5, including the following.

  • Worn / damaged weatherstripping
  • Clogged drainage holes
  • Improperly sealed hatch
  • Rust / corrosion

1. Worn or Damaged Weatherstripping

The weatherstripping around the hatch is designed to seal the hatch area and prevent water from entering the vehicle.

If the weatherstripping is worn or damaged, it can allow water to enter the hatch area and cause a leak.

2. Clogged Drainage Holes

The Mazda 5 has drain holes in the hatch area to allow water to drain out. If these drain holes are clogged, water can build up and cause a leak.

3. Improperly Sealed Hatch

If the hatch is not properly sealed when closed, it can allow water to enter the vehicle. This can be caused by a problem with the latch or the weatherstripping around the hatch.

4. Rust or Corrosion

If the hatch area is rusting or corroding, it can cause a leak.

How to Fix a Mazda 5 Hatch Leak

If you are experiencing a hatch leak in your Mazda 5, there are a few steps you can take to fix the problem.

1. Inspect the Weatherstripping

Begin by inspecting the weatherstripping around the hatch for any signs of wear or damage. If the weatherstripping is worn or damaged, it will need to be replaced.

2. Check the Drain Holes

Next, check the drain holes in the hatch area to ensure they are not clogged. If they are clogged, clear them out using a small wire or similar tool.

3. Check the Hatch Seal

Make sure the hatch is properly sealed when closed by inspecting the latch and the weatherstripping around the hatch. If there are any problems with the seal, it will need to be repaired.

4. Repair Rust or Corrosion

If the hatch area is rusting or corroding, it will need to be repaired.

Use a rust inhibitor (such as this one on Amazon) after removing loose rust with a wire brush to remove any rust, and then apply a rust-inhibiting paint to protect the area from further corrosion.

5. Test the Hatch

Once you have completed the above steps, test the hatch by filling a bucket with water and pouring it over the hatch area. If the hatch is properly sealed, the water should not leak into the vehicle.

Conclusion

A hatch leak in a Mazda 5 can be a frustrating and potentially dangerous problem.

By identifying the cause of the leak and taking the appropriate steps to fix it, you can help to protect your vehicle from water damage and ensure the hatch is properly sealed.

Use a rust inhibiting paint after removing or priming rust to prevent further rust from forming.
