What is not covered

Every guide from 2017 through 2027 states that the New Vehicle Limited Warranty does not cover damage or failures resulting directly from:

  • Fire, accidents or theft.
  • Abuse or negligence.
  • Misuse, for example racing or overloading.
  • Improper repairs.
  • Alteration or tampering, including installation of non-Genuine Toyota Accessories.
  • Lack of or improper maintenance, including use of fluids and fuel other than those specified in the Owner's Manual.
  • Installation of non-Genuine Toyota Parts (2017–2020); installation of parts that are not Toyota Genuine Parts (2021–2027).
  • Airborne chemicals, tree sap, road debris (including stone chips), rail dust, salt, hail, floods, wind storms, lightning and other environmental conditions.
  • Water contamination.

The 2025, 2026 and 2027 guides add two items to that list: damage that occurs as a result of abuse or misuse of the vehicle while participating in an HPDE/track event, or off-road use; and wear or damage from competitive motorsports events. The 2027 guide also adds, as the first item: neglecting to follow appropriate vehicle usage, incorrect charging procedure or use of an incompatible charging device that results in a battery capacity reduction.

Each guide's list of what the warranty also does not cover includes:

  • Gradual capacity reduction of the lithium-ion traction battery.
  • Any vehicle that has ever been issued a salvage or similar title (2017–2020), or branded as salvage, total loss, true mileage unknown or similar title (2021–2027), under any state's law, or declared a total loss or equivalent by a financial institution or insurer. This exclusion does not apply to the emission control warranties.

Scope note

US market, model years 2017 through 2027, from Toyota's warranty guides for each of those years; Toyota names the car Prius Prime in the 2017–2024 guides and Prius Plug-in Hybrid in the 2025, 2026 and 2027 guides. The guide delivered with a specific car is the authority for that car.
