What is a Powertrain Warranty?

All new vehicles come with factory warranties. However, keep in mind that these manufacturer’s warranties do not cover everything that may go wrong with a car. The powertrain warranty is one of the most important warranties available, but you may be wondering exactly what does it cover. We will guide you through this thorough explanation and answer any question you may have about powertrain car warranties.

Warranties, Extended Warranties, and Powertrain Protection Plans

A warranty is a formal guarantee that the manufacturer of a product makes, promising that their product will perform in a particular way for a specific period of time. It is put into place in the event that the product doesn’t perform precisely as specified within the warranty period. If this is the case, the manufacturer will repair or replace it.

When the original manufacturer’s warranty has expired, sometimes manufacturers will choose to offer additional protection, known as an extended warranty. Think how when you buy a new Apple device, you can purchase AppleCare to protect your device once the original warranty has expired.

However, if the original manufacturer does not offer an extended warranty, there are third-party options available in the form or a protection plan or service contract. These are not called warranties because they did not come directly from the manufacturer, but rather a third-party provider.

What is the Powertrain?


To understand more about powertrain warranties, we will first detail the parts and components of the Powertrain. The components of a vehicle’s powertrain include:

  • Engine
  • Driveshaft
  • Transmission
  • Transfer Case (for four-wheel and all-wheel drive vehicles)
  • Differential
  • Internal Working Components of an Engine

Why Are the Powertrain Components so Important?

The powertrain system of a car provides and converts power to it. Keep in mind that the term “powertrain” may also apply to motorbikes, airplanes, boats, and various other pieces of machinery, which use an engine for power.

To understand your specific coverage, it is important to know what is and is not part of your car’s powertrain. In simple words, the parts or components that mechanically propel a car make up its powertrain.

The Engine


Your car’s engine is an extremely important piece of this powertrain puzzle, if not the most important. The engine burns air and fuel in order to generate power for moving your vehicle.

Keep in mind that the car engine itself, as mentioned in the powertrain warranty, is the whole engine block and it also has internal components.

The parts and components of the engine block can include:

  • Hoses
  • Sensors
  • Bolt-on Components

Internal parts and components of the engine itself can include:

  • Pistons
  • Crankshaft
  • Timing Belt
  • Gears
  • Exhaust and Intake Valves
  • Oil Pump

Keeping the engine maintained adequately with frequent oil changes is key to ensuring that your car’s powertrain warranty is valid. It is worth mentioning that modifications, neglected maintenance, and physical damage to your car may result in a powertrain warranty claim on the engine being rejected.



The differential uses rotational movement from the car’s longitudinal axis and converts it into rotational movement on your latitudinal axis (this is side-to-side), your car wheel will turn as a result. Keep in mind that a differential uses gears which mesh together in order to make this happen.

On a front-wheel drive vehicle, the front differential is often included internally inside the transmission. While on a four-wheel drive or rear-wheel drive vehicle, it is external, as is the case with a rear differential on all-wheel drive vehicles.

If the differential is built into your transmission, the maintenance will be performed at the same time as the transmission service. If it is external, be sure to change the fluid at regular intervals or have a trusted mechanic do it. If you do not, your powertrain warranty may be voided.



The transmission gets its input from a rotating crankshaft in the engine and adjusts it to seamlessly shift gears as well as change directions from forward to reverse and vice versa. Similar to the engine, its internal parts and case are generally included as part of the powertrain warranty.

While these parts are generally included, sensors and wiring (or cables) on a transmission usually are not covered. A great thing to note about the transmission is that they need infrequent maintenance. However, you have to perform it on time to make sure that your powertrain warranty remains intact.

Transfer Case

In most cases, the transfer case works by attaching itself to the car transmission and sending rotational power to your car’s front or rear differential through drive shafts. So, if your car has a transfer case, you have to change the fluid according to the car manufacturer’s recommended maintenance schedule.

Keep in mind that only those vehicles that have all-wheel or four-wheel drive have transfer cases. The function of a transfer case is to transmit power to the suitable set of wheels, rear or front, in accordance with the input the case gets from a vehicle’s settings.

Remember that any failures because of abuse or lack of proper maintenance are more likely to be denied.

Should You Buy an Extended Powertrain Warranty?

In most cases, engine coverage usually includes the following:

  • Cylinder Block and Heads
  • Oil Pan
  • Internal Parts
  • Valve Train
  • Water, Oil, and Fuel Pump
  • Fuel Injectors
  • Flywheel
  • Gaskets and Seals

Some powertrain warranties may also include coverage for items such as:

  • Hubs and Wheel Bearings
  • Axle Shafts
  • Intake Manifolds and Exhaust

How an Extended Powertrain Warranty Works

When a car owner purchases an extended powertrain warranty, they expect their car to be covered in the event that a malfunction or mechanical failure occurs. Particular coverage plans tend to offer coverage for specific things.

This is why it is extremely important that you know exactly what is and is not covered in order to avoid any potential problems and hassles when repairs have to be made.

If you have a vehicle service contract from Endurance- commonly referred to as an extended auto warranty, and require repairs, you can take your car to any repair facility of your choice, as long as the facility has ASE-certification. Before making the repairs, the auto repair facility will contact Endurance in order to report that a claim needs to be filed before repairs are made.

Once we have verified that your vehicle service contract is up to date, we pay the repair facility directly for covered repairs. Keep in mind that you would be responsible for paying the deductible, if any, that is required for your plan. The majority of plans tend to have a normal deductible of $100 while others offer $50 or even $0.

Imagine getting thousands of dollars of repairs done to your vehicle and only having to pay $100!

Benefits of Extended Powertrain Warranties

As a smart consumer, you already know that the better care you take of your car, the longer it will last. As a result, you might be diligently committed to the manufacturer’s recommended maintenance. While Endurance strongly encourages doing so, routine maintenance is just not enough to protect your car.

No matter how well a car is manufactured, whether it may be an Audi, Buick, or Cadillac, all cars eventually break down. And once your manufacturer’s warranty expires, you are left responsible for paying for repairs.

With common repairs costing hundreds or even thousands of dollars, there is no reason a driver should be driving without vehicle protection. Your factory powertrain warranty was put into place as a guarantee of manufacturer defects, and you aren’t likely to have serious issues while it is in place.

In fact, numerous automotive research sites show that your powertrain components are most likely to fail outside of the manufacturer warranty timeframe.

Outside of protecting you from the high-cost of auto repairs, a powertrain protection plan can help you in the following ways.

Protection Plans Only Increase Resale Value

A very important reason why extended warranties are popular, is that it can increase your vehicle’s resale value. When most buyers purchase a car, it is difficult to imagine selling that car. But, as time flies by, you might decide you would like to upgrade to a better and newer model.

If and when that time comes, offering a protection plan with your car from Endurance is an incredible selling point.

It not only provides the exact same protection that was so valuable to you, it also informs the potential car buyer that you maintained your car well, and opted for additional protection in the event anything breaks down.

Being able to resell your car with peace of mind for you AND the buyer is a way to not only keep your car’s resale value intact, but to even potentially increase it!

The Easiest Way to Save Money on Car Repairs
