Are rust and corrosion appearing early on Changan Karvaan body panels, especially in coastal areas like Karachi o r humid regions of Punjab?

Some owners notice rust near doors, underbody, and wheel arches. Is the vehicle missing proper anti-rust coating o r paint protection?

Yes, users in coastal Karachi and humid areas Punjab report early rusting:

Common areas: door frames, wheel arches, underbody, and rear sliding door channels.

Possible causes:

Absence of proper anti-rust undercoating.

Subpar sealing and welding joints.

Low-quality metal treatment at the manufacturing stage.

⛔ Conclusion: The van lacks proper rust-proofing for Pakistani humidity and coastal salt exposure.
