When it comes to extended warranties, there are two primary types: those offered by the carmakers (also known as original equipment manufacturers or OEMs) and aftermarket warranties offered by third-party vendors. An OEM would be a carmaker such as Chevrolet, Ford or Toyota. A third party would be an insurance or warranty company that isn’t directly affiliated with a car brand.
A bumper-to-bumper (sometimes called “limited”) warranty will cover most other items in the vehicle. In addition to major components under the hood, bumper-to-bumper warranties also cover things like navigation systems, power seats, onboard computers and various other electronics.
An extended warranty from an OEM will usually mimic what it offered when the vehicle was new, extending the length of the coverage and the allotted mileage. Some will throw in extra benefits such as roadside assistance.
