What Is A Bumper-To-Bumper Extended Warranty?

A bumper-to-bumper extended warranty refers to the most comprehensive, highest level of coverage that an extended car warranty provider offers. Coverage details vary by provider, but most cover the vehicle’s major mechanical and electrical systems with the exception of a short list of items excluded from coverage.

What Does A Bumper-To-Bumper Extended Warranty Cover?

Bumper-to-bumper extended warranty coverage plans generally cover the following vehicle components:

  • Audio, communication, and entertainment systems
  • Heating and air conditioning
  • Electrical (power seats, sunroofs, heated seats)
  • Powertrain components (engine, transmission, certain driveline parts)
  • Engine cooling system
  • Steering system
  • Suspension
  • Fuel injection system

Despite the name, bumper-to-bumper coverage does not cover every car repair or part. Exact coverage details differ depending on the provider, but every bumper-to-bumper warranty comes with a brief list of car parts that are excluded from coverage, including the bumpers. That’s why bumper-to-bumper extended warranty plans are more accurately referred to as “exclusionary warranties.”

Coverage Exclusions

Common exclusions to a bumper-to-bumper extended warranty are as follows:

  • Wear-and-tear items: Brake pads, rotors, drums, upholstery, seat belts, and more
  • Routine maintenance: Oil changes, tire rotations, wheel alignment, and scheduled service as
  • recommended by the manufacturer-recommended service schedule
  • Automotive glass parts: Headlights, brake lights, windows, and windshields
  • Damage: Abuse, misuse, neglect, collisions, use of improper fluids, fuels, or lubricants, acts of
  • nature, and more

Most of the items not included in bumper-to-bumper extended warranty coverage are covered by other plans such as a pre-paid maintenance plan from your car’s manufacturer’s warranty or coverage provided through your car insurance company.

Bumper-To-Bumper Vs. Powertrain Extended Warranty

There may be some confusion around the difference between the two main types of vehicle service contracts: bumper-to-bumper extended warranties and powertrain extended warranties. These plans often differ in term lengths and always differ in the level of coverage provided.

  • Bumper-to-bumper extended warranty: This comprehensive, high-level coverage protects most of your car’s parts and electronic systems and typically lasts for 3 years/36,000 miles.
  • Powertrain extended warranty: Powertrain warranties protect the most vital parts of your vehicle that deliver energy from the engine to the wheels, including the engine, transmission, drive axle, and suspension parts. Most powertrain coverage plans last around 5 years/60,000 miles.

Bumper-To-Bumper Extended Warranty Cost

Typically, bumper-to-bumper extended warranty plans cost more than powertrain warranties because of the heightened level of coverage, however this will vary depending on several factors. The cost of a bumper-to-bumper warranty will be determined by:

  • The extended warranty provider you select
  • The level of coverage you choose
  • Your vehicle’s mileage, year, make, and model

Which Bumper-To-Bumper Extended Warranty Is Best For You?

While auto brands tend to offer comprehensive extended warranties with one or two levels of coverage, third-party warranty providers usually offer variations that let you tailor the level of coverage to your particular needs. Examine all the plans a provider offers, and then see which level of coverage and length of coverage makes the most sense for the price.

Here’s a closer look at what you can get with Endurance and CARCHEX, as well as our pick for Best Value, CarShield.

    • Endurance offers a top-level exclusionary plan called Supreme. All Endurance plans include Endurance Elite Benefits, which includes perks like 24/7 roadside assistance and one year of key fob replacement coverage. (On many new vehicles, these sophisticated items can cost several hundred dollars to replace.) In addition, the membership covers up to two tire repairs or replacements per year.
    • CARCHEX offers several comprehensive plans, including the top-of-line Titanium. The Titanium plan is a true exclusionary extended warranty, similar to a bumper-to-bumper plan. This means it covers everything on the vehicle minus a short list of excluded parts. You also get benefits like roadside assistance and rental car reimbursement.
    • CarShield offers Diamond coverage that essentially duplicates what a new vehicle warranty offers. The popular provider is known for its low rates and benefits like roadside assistance and trip interruption coverage. Learn more about plans and benefits in our full CarShield review.

Look For These Must-Have Warranty Benefits

When considering an extended warranty plan, whether from the dealership or a car warranty company, make sure the plan is transferable if you sell the vehicle (most are), and look for the following benefits:

      • 24/7 roadside assistance
      • Rental car reimbursement
      • Towing coverage
      • Trip interruption service or reimbursement
      • Choice of deductible
      • Monthly payment plan

It’s also a good idea to research a company’s industry standing. Some providers, like Toco, are known for their transparent business practices and reputation for paying out customer claims.
