What is the Lexus corrosion warranty?
The corrosion warranty on Lexus vehicles primarily covers rust perforation on body sheet metal for six years from the date of first use, with unlimited miles. It does not cover cosmetic rust or rust that does not penetrate the metal.
In practice, this warranty is part of Lexus’s New Vehicle Limited Warranty and is designed to protect against perforation rust that compromises the structural integrity of the body. Terms can vary by model year and region, so it’s important to consult your owner’s manual or a Lexus dealer for the exact coverage that applies to your car. The warranty is generally transferable to subsequent owners and claims are processed by authorized Lexus service centers.
What the corrosion warranty covers
The following points outline the scope of the Rust-Through Limited Warranty as it pertains to body-sheet-metal perforation.
- Rust perforation (holes) in the body sheet metal caused by corrosion that penetrates through to the interior of the panel.
- Coverage duration of six years from the date of first use, with no mileage limitation within that period.
- Repair or replacement of the affected body components as determined by an authorized Lexus service center.
- Transferability to subsequent owners at no additional charge in most markets.
- Coverage is typically limited to manufacturer-installed body panels and related structural components.
In short, if rust progresses to perforation in the body panels within six years and under normal use, repairs under the warranty are available subject to the terms and region-specific conditions.
What is not covered
Not all rust issues fall under the corrosion warranty. The following exclusions commonly apply.
- Surface rust, cosmetic rust, or any rust that does not perforate the sheet metal.
- Rust caused by accidents, collisions, or external damage such as stones or debris that create openings.
- Rust resulting from improper maintenance, vehicle modification, exposure to chemicals, or abnormal environmental conditions beyond normal use.
- Rust on non-body-sheet components (for example, interior trim, non-structural parts, or non-metallic surfaces).
- Repairs or replacements not deemed necessary or not approved by an authorized Lexus service center.
Because terms can vary by year and region, always confirm these exclusions with a local Lexus dealer.
How to file a claim and transferability
Understanding the process helps owners act quickly when perforation is suspected. The following steps outline typical procedures.
- Schedule an appointment with an authorized Lexus dealer or service center to assess the issue.
- Bring proof of ownership, the vehicle’s VIN, and documentation showing the date of first use (or purchase) to establish warranty eligibility.
- Have the vehicle inspected by a Lexus technician to determine whether the rust perforation qualifies under the Rust-Through Limited Warranty.
- If approved, the dealer will repair or replace the affected body panels using appropriate OEM parts and methods.
- If ownership changes, inform the dealer to maintain warranty coverage; keep all repair records for resale purposes.
Process reliability and coverage can depend on the specific market and vehicle year, so consult your local dealer for exact steps and required documentation.
Regional variations and additional notes
Warranty terms can differ by country and model year. The following notes provide a general sense of regional differences found in many markets.
- United States: The Rust-Through Limited Warranty commonly covers perforation rust on body panels for six years from first use, with unlimited miles, and is usually transferable to subsequent owners.
- Canada and other regions: Terms may vary; check the official Lexus regional handbook or contact a local dealer for precise coverage, duration, and transferability details.
Because regional terms can differ, always verify the exact coverage with your local Lexus dealer or refer to the warranty documentation provided with your vehicle.
