Is an extended warranty worth it on a 2020 Toyota Prius?
Math is straightforward: a quality service contract runs $1,800–3,500 over 3 years. With 14 complaints on file, one major failure more than pays for it. The catch is reading the contract — many providers exclude wear items and require pre-authorization, so cheaper plans are not always better value.
