  • The 2023 guide (March 2025 Fifth Printing) and the 2024, 2025 and 2026 guides add: for new retail sales on or after July 1, 2023 sold from a California retailer and/or to a California resident, the Warranty Start Date and mileage start no earlier than when the goods are delivered to the customer.

What is not covered

Under "Damage Caused By," Ford's guides for every model year 2021 through 2026 exclude damage caused by:

  • Accidents, collision or objects striking the vehicle, including driving through a car wash.
  • Theft, vandalism, or riot.
  • Fire or explosion.
  • Using contaminated or improper fluids.
  • Customer-applied chemicals or accidental spills.
  • Driving through water deep enough to cause water to be ingested into any component.
  • Immersion or flooding of the high voltage battery assembly.
  • Abuse or misuse of the vehicle or the high voltage battery pack, such as driving over curbs, overloading, racing, or using the vehicle as a permanent stationary power source.
  • Exceeding the load limits specified on the certification label.
  • Failing to observe and resolve vehicle warnings and indications of battery concerns within a reasonable amount of time, which the guides give as "typically 30 days."
  • Failing to complete software updates within a reasonable amount of time, which the guides give as "typically 30 days"; the 2022 through 2026 guides name these Ford Power-Up software updates.
  • The use of incompatible charging devices or methods.
  • Modifications to the high voltage battery assembly, high voltage system, or associated wiring.
  • Exposure to direct or intense heat sources outside of normal use, such as collision repairs that subject the vehicle to paint booth conditions that exceed Ford's recommendations.
  • Allowing the high voltage battery assembly to remain fully discharged, or at a near zero state of charge, for more than 14 days.
  • Repairs performed by facilities and personnel not authorized by Ford.
  • Improper vehicle storage resulting in high voltage battery damage.

Every guide also states that the New Vehicle Limited Warranty does not cover:

  • "vehicles that have ever been labeled or branded as dismantled, fire, flood, junk, rebuilt, reconstructed, or salvaged; this will void the New Vehicle Limited Warranty"
  • "vehicles that have been determined to be a total loss by an insurance company; this will void the New Vehicle Limited Warranty"

Scope note

US market, model years 2021 through 2026, from Ford's US Battery Electric Vehicle Warranty Guide for each of those years, all served from Ford's own fordservicecontent.com host; the 2021 guide is a Mustang Mach-E edition and the 2022 through 2026 guides cover the E-Transit, Mustang Mach-E and F-150 Lightning together. No 2027 guide was found on that host, so model year 2027 carries no row here. The guide delivered with a specific car is the authority for that car.
