A car’s powertrain is made up of the parts that make it run. Such parts include the transmission, the engine, and the drivetrain (the components that get the power from the engine to the wheels and down to the ground). It is a large system that consists of many moving parts. If any part of the powertrain fails, there is less of a chance that you will actually get where you need to go. The car’s powertrain features and engine specs are vital to making the car run.

A powertrain auto warranty covers the powertrain components if they are found defective or if they are damaged within a specific time period. This means that the manufacturer will pay to have the faulty components replaced or repaired. The powertrain warranty usually has a year or mileage (whichever comes first) period of coverage and it expires when the designated period is up. This warranty generally lasts for a longer time period than other manufacturer warranties, like the bumper-to-bumper warranty.

Powertrain auto warranty coverage generally excludes parts that wear such as CV joints and boots, clutches, and other parts that have a small lifespan and need to be replaced at regular intervals or sooner depending upon how well the car is maintained or how hard it is driven.
