The Importance of a Car Rust Warranty

Most new vehicles come with a car rust warranty, which usually includes corrosion coverage. This coverage can vary, but generally, it provides significant protection against rust damage. There are two main types of coverage: rust perforation and surface corrosion.

Types of Rust Warranty Coverage

Rust perforation coverage typically addresses rust that has penetrated the metal. It covers the costs of repairing or replacing parts where rust has created holes. On the other hand, surface corrosion coverage deals with rust resulting from paint scratches, road salt, or other surface-level damages.

Duration and Extent of Coverage

The duration and specifics of a car rust warranty can differ greatly among manufacturers. Some manufacturers might offer rust perforation coverage for up to 7 years and surface corrosion coverage for up to 12 years. For example, Toyota and Chrysler offer comprehensive rust warranties on body panels and corrosion issues for up to 5-7 years.
