What is not covered

Chevrolet excludes from the New Vehicle Limited Warranty:

  • On 2025 and later cars, damage to the battery from incompatible charging methods, or from use of an adapter that General Motors does not sell or approve.
  • On 2025 and later cars, excessive use of the main battery for non-propulsion purposes, including semi-permanent or permanent daily power provisions. GM reserves the right to curtail non-propulsion use it determines is harmful to the battery.
  • Alteration, modification or tampering with the vehicle after final assembly, including its software; installation of non-GM parts; water or fluid contamination.
  • Collision, fire, theft, freezing, vandalism, riot, explosion, or objects striking the vehicle.
  • Damage from failure to follow the recommended maintenance schedule intervals.
  • Any vehicle whose odometer has been disconnected or altered, or whose mileage cannot be determined; the warranty is void on vehicles currently or previously titled as salvaged, scrapped, junked or otherwise considered a total loss.
  • Economic loss and extra expense, including inconvenience, lodging and meals, loss of vehicle use, loss of time or pay, and storage.

Scope note

Chevrolet writes one electric-vehicle warranty booklet per model year covering its whole EV line rather than one per model, and the 2024, 2025, 2026 and 2027 editions are the ones read here; the Blazer EV is not named in any of them, and the model-specific 8-year/100,000-mile term comes from Chevrolet's own Blazer EV specification pages. The California ZEV section appears in the 2026 edition, and the two exclusions marked 2025 and later were added after the 2024 edition. The booklet delivered with a specific car is the authority for that car.
