1st-gen Matrix models are prone to rust at the rocker panels, rear wheel arches, and rear hatch seam areas in salt-belt regions. The rust starts from inside the rocker panel and works outward, often being severe before it becomes visible on the exterior.
Common Symptoms
- Bubbling paint on rocker panels
- Rust perforation at rear wheel arches
- Visible rust at rear hatch seams
- Rocker panels soft to the touch

How to Fix
For early rust: sand to bare metal, treat with POR-15 or Eastwood Rust Encapsulator, prime and paint. Moderate rust: cut out affected metal and weld in patch panels.
