A bumper-to-bumper warranty is a type of car warranty that provides comprehensive coverage for most vehicle systems between the front and rear bumpers of a car. It is also known as a comprehensive warranty or new car limited warranty. Bumper-to-bumper coverage comes standard on new vehicles along with powertrain, drivetrain, corrosion, and rust warranties. Most new cars come with either a three- or five-year bumper-to-bumper warranty that’s part of a limited vehicle service contract offered by the dealership. Bumper-to-bumper warranties cover repairs to almost all parts between a vehicle’s front and rear bumpers, including audio, communication, and entertainment systems, air conditioning and heating, and interior trims, upholstery, and seat belts. However, they do not cover wear items such as brakes, wiper blades, or tires, or periodic maintenance like oil changes or wheel alignments. Bumper-to-bumper warranties are the most comprehensive level of car warranty coverage that promises to pay for repairs to most car parts and systems in the event of a mechanical breakdown.
