The bZ4X, Toyota’s all-electric SUV, relies on a high-voltage battery pack. This article outlines current warranty terms, what is covered, and how regional differences can affect your protections as of 2025.
What the warranty covers
The following items describe the typical inclusions and exclusions under the bZ4X high-voltage battery warranty.
- Coverage for defects in materials or workmanship in the high-voltage battery pack.
- Coverage extends to related high-voltage components essential to battery operation (such as battery control electronics, inverter/charger, and cooling components) when defects are the cause.
- If a covered defect occurs during the warranty period, Toyota will repair or replace the battery or related components at no cost to the owner.
- Exclusions generally include damage from accidents, improper charging or use of non-Toyota-approved charging equipment, misuse or modification, environmental damage, cosmetic damage, and normal wear and tear.
In practice, the warranty focuses on defects rather than guaranteeing a specific capacity after years of use. Always verify the exact terms for your model year and region with a Toyota dealer or the official Toyota warranty documentation.
