A car warranty extends from a minimal 1 year, more common 3 year and extended 5 years. While some car manufacturers have gone as far as 10 years. Crate Engine manufacturers also give warranties based on the manufacturers' and workmanship warranties.

Some companies also offer extended warranties or used car warranties for vehicles up to 12 years old. One can usually buy a warranty from an insurance company or insurance coverholder. The term extended warranty is generally misleading. Non-manufacturer based warranties are technically called motor vehicle service agreements or service contracts. In states which license service contract companies, those companies are required to not sell them as warranties.
