Depending on what is being repaired, the length of a factory warranty varies. Often a comprehensive “bumper-to-bumper” warranty covers everything outside of schedule maintenance. This is generally the shortest warranty period. Usually a longer powertrain warranty covers engine and transmission defects. Anti-corrosion protection often lasts even longer. Finally, some manufacturers offer roadside assistance for a limited time. Check your vehicles maintenance guide to determine your vehicle’s needs. New Chrysler, Dodge, Jeep, Ram, and FIAT products include a 3-year/60,000km comprehensive warranty, a 5-year/100,000km powertrain warranty (160,000km on Cummins diesel engines), and a 5-year/100,000km 24-hour roadside assistance coverage.
