Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components such as air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance such as fluid top-offs and oil changes, but a growing number of brands have separate free-maintenance provisions. Bumper-to-bumper warranties typically expire faster than powertrain warranties. Terms are typically three years or 36,000 miles, although some have terms as high as six years or 60,000 miles. Check the vehicle manufacturer’s specifications for bumper-to-bumper warranty limits.
