Manufacturers typically include a powertrain warranty with all new vehicles, but what exactly is a powertrain, and what’s protected under this type of coverage?

In this article, we’ll discuss the ins and outs of powertrain warranties, including what’s covered, how long coverage typically lasts, and which manufacturers and third-party providers offer the best powertrain plans.

When shopping for a powertrain warranty, it’s a good idea to compare prices from multiple warranty companies. We’ve narrowed down the best extended car warranty providers in the industry, and you can get free, personalized quotes from each company by clicking above.

What Does a Powertrain Warranty Cover?

A powertrain warranty covers your car’s most vital components, including the engine, transmission, and drive axle. These are the parts that deliver energy from the engine to the wheels to keep your car moving.

Powertrain components are some of the most expensive to repair or replace if they break down, so a powertrain warranty can be an economical investment for many drivers.

How Much Does a Powertrain Warranty Cost?

Each auto manufacturer includes powertrain warranty coverage at no additional cost when you purchase a new vehicle from a dealership. Many automakers also include powertrain coverage with the purchase of a certified pre-owned vehicle. However, in both cases, your powertrain warranty will eventually expire, leaving you on your own to cover potentially costly repairs.

You can lengthen your powertrain warranty with an extended warranty from your vehicle’s manufacturer or a third-party provider. With either option, there is no set price for warranty coverage. The cost of a powertrain warranty will vary from driver to driver and will depend on factors such as:

  • The vehicle you drive: If you drive a luxury car or a vehicle that has many high-tech components, it will likely cost more to cover.
  • The age and mileage of your vehicle: Older, higher-mileage vehicles are more expensive to cover because they’re more prone to breakdowns.
  • Where you purchase coverage: The cost to extend your powertrain warranty through your car manufacturer is typically more than you’d pay for an aftermarket warranty.
  • The plan you choose: Many providers offer basic powertrain plans as well as enhanced plans that cover powertrain components as well as other major vehicle systems, such as the suspension and air conditioning.
  • The deductible you choose: If you have the option to choose your deductible, picking a lower deductible will result in a higher total warranty price, and vice versa.

We requested quotes from the industry’s top warranty companies to get a better sense of average extended powertrain warranty costs. The chart below shows the cost of powertrain coverage for a 2020 Hyundai Elantra with 60,000 miles on it from our top two extended car warranty providers: Endurance and CARCHEX.

Although the exact price of coverage can vary greatly depending on the specific model of your car and number of miles on the odometer, these prices provide an idea of how much a powertrain warranty can cost.

Are Powertrain Warranties Worth It?

As mentioned, vehicles become more likely to break down as they age. Many drivers find that having powertrain protection adds peace of mind on the road, as they know they’ll be covered in the case of a major, expensive breakdown such as engine or transmission failure.

Powertrain coverage could also be well worth it for drivers who:

  • Own a vehicle with low reliability ratings
  • Own a vehicle model that is prone to engine failure or transmission issues
  • Want to finance the cost of repairs over time rather than pay a lump sum out of pocket when an unexpected repair is needed
  • Do not want bumper-to-bumper warranty coverage for high-tech systems and electronic parts

Bumper-to-Bumper vs. Powertrain Warranty

Bumper-to-bumper warranties and powertrain warranties are the two main types of vehicle service contracts. “Bumper-to-bumper” is a term used to refer to a provider’s highest level of coverage that protects the most vehicle components.

Here’s a breakdown of how bumper-to-bumper plans compare with powertrain warranties:

Bumper-to-Bumper Warranty

Powertrain Warranty

Type of Contract

Exclusionary contract: Contracts only list the parts that are not covered

Stated-component contract: Contracts list every part that is covered

Level of Coverage

High-level coverage: Comprehensive coverage that encompasses most vehicle parts, including high-tech components

Basic coverage: Less comprehensive coverage that only protects core components, not high-tech or electrical parts

Coverage Length

Shorter coverage: Most manufacturers’ bumper-to-bumper warranties last 3 years/36,000 miles

Longer coverage: Most manufacturers’ powertrain warranties last 5 years/60,000 miles

However, bumper-to-bumper and powertrain warranties are not customers’ only options. A “powertrain plus” warranty refers to a level of coverage that is a step above a powertrain warranty but that’s still less comprehensive than bumper-to-bumper coverage.

There is also a less-widely available warranty that only protects the drivetrain parts of your vehicle, or the transmission and drive axles. Often mistakenly used interchangeably, drivetrain warranty and powertrain warranty plans are different in that a powertrain warranty protects the engine whereas a drivetrain warranty does not.

How Long Does Powertrain Warranty Coverage Last?

The average length of a powertrain warranty is 5 years/60,000 miles, but some manufacturers offer powertrain protection up to 10 years/100,000 miles.

If you buy a powertrain warranty from a manufacturer, you may be able to extend your coverage up to 150,000 miles. Third-party warranty companies may offer plans up to 250,000 miles.

What Voids a Powertrain Warranty?

Your powertrain coverage could be voided if:

  • You do not keep up with your vehicle’s recommended maintenance schedule as outlined in your owner’s manual
  • Your car receives a salvage title or is declared a total loss
  • You misuse your vehicle by racing, towing an oversized load, off-roading, or other abuse
  • You incur a certain amount of severe environmental damage from an event such as a flood or fire
  • You alter or tamper with your odometer
  • You use improper fuels and fluids that compromise your powertrain’s function

Which Car Manufacturer Has the Best Powertrain Warranty?

Figuring out which automaker has the best warranty can help customers find the best powertrain protection. The three manufacturers that currently offer the longest powertrain warranty coverage are Hyundai, Mitsubishi, and Kia. These brands offer a 10-year/100,000-mile powertrain warranty on all new vehicles.

As far as luxury vehicles go, Hyundai’s Genesis brand also offers 10-year/100,000-mile powertrain warranty coverage. Genesis is the only luxury brand to offer this length of coverage. Lexus has a good powertrain protection plan in place, providing 6 years/60,000 miles of coverage.
