The 2014 Chevy Silverado came with a three-year/36,000-mile factory warranty and a five-year/100,000 mile powertrain warranty. Unfortunately, because of your vehicle’s age, the original manufacturer coverage will no longer apply.
However, if you want to protect your car against some mechanical failures, you can buy an extended warranty through a third party such as CarShield or Endurance. These companies offer warranty plans similar to your vehicle’s factory coverage, and could help you pay for things like engine malfunctions or problems with your drivetrain, brakes, transmission, or suspension.
