Defining a Powertrain Warranty

A warranty covering the costs of the parts that are in charge of propelling your car mechanically is known as a powertrain warranty. The included components of this type of warranty are the engine, which will turn the driveshaft through the transmission.

Power is provided and converted to a vehicle by the powertrain system. Boats, motorbikes, airplanes, and various other pieces of machinery may also have the term powertrain applied to them, as they also use an engine to receive power. 

We believe it is vital for consumers to research and become familiar with their powertrain warranty to understand what it does and does not cover their coverage plan agreement. To better understand this type of warranty, we will first go over the components and the parts of the powertrain. Below is a list of the powertrain of a vehicle:

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

Insurance and Extended Car Warranty: The Difference

In simplified terms, extended warranties cover the maintenance of a car and any faulty components in vehicles. At the same time, insurance is used to protect your vehicle in the event an accident occurs. 

Having a warranty is like having a formal guarantee straight from the manufacturers of products, which promises that the product they made will function for a specific purpose for an estimated amount of time that has been predetermined. When a product, which in this instance will be a vehicle, does not perform in the way it was specifically designed to do after it has been purchased, a warranty will be put into place. 

There are some occurrences where, after the original warranty on a vehicle expires, the manufacturer will decide to offer the additional consumer protection, which is known as an extended warranty. 

In case you do not fully understand what we mean, compare this to the following. Imagine going out to purchase a new item and being asked if you want to buy the protection plan. Apple devices are a perfect example of AppleCare’s offer to its consumers after the product’s original warranty expiration. Suppose the original manufacturer does not provide an extended warranty. In that case, there are some options available from third-parties in the form of a vehicle service contract or a protection plan. 

Warranties can come in various forms; however, the most basic warranty available is the powertrain warranty. Your vehicle’s costlier parts are covered by the powertrain warranty, which can save you thousands of dollars. 

All About Engines

The most essential piece of equipment in the powertrain collection is the engine of a vehicle. Air and fuel are burned by the engine for power to be generated, which helps your vehicle to be able to move. As mentioned previously in the powertrain warranty, the car engine itself is the complete engine block and the internal components. 

The components and parts of the engine block could include the following:

  • Bolt-on Components
  • Hoses
  • Sensors

The components and internal parts of the engine itself could include the following:

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

To ensure that the powertrain warranty is valid for your car, you will need to keep the engine maintained properly by giving the vehicle frequent oil changes. It is important to note that physical damage, modifications, and neglected maintenance can potentially cause a powertrain warranty claim on the engine to be rejected.

Understanding Differentials

The differential uses rotational movement from the car’s longitudinal axis as it is converting it into rotational movement on the latitudinal axis, meaning that your car wheel will then turn as a result.

Gears are used by a differential as the mesh together to make this occur. The front differential is often included for a front-wheel-drive vehicle, and it is located internally inside the transmission. They are external, just as they are with rear differentials on all-wheel-drive vehicles on a rear-wheel drive or four-wheel drive.

Maintenance can be performed at the same time that the transmission is serviced if the differential has been built into the vehicle’s transmission. If it is external, just make sure that you are changing the car’s fluids at regular intervals or have a mechanic you trust to handle it. Otherwise, you may void your powertrain warranty. 

About Transmissions

The transmission is the second component for a powertrain warranty. A rotating crankshaft within the engine is how the transmission gets its input. It will seamlessly adjust for shifting gears and change the vehicle’s directions from reverse to forward interchangeably.  

As part of the powertrain warranty, the transmission’s internal components and case are typically included, just like the engine.  Most of these parts typically are included, but wiring or cables and sensors on a transmission usually are not covered. The good thing about transmissions is that they do not need to be maintained frequently. However, you do need to make sure you are performing maintenance on the transmission on time to ensure that you retain your powertrain warranty. 

Transfer Cases

A transfer case will attach itself to the car’s transmission and send rotational power to the rear or front differential of the vehicle by using the drive shafts. If you have a vehicle with a transfer case, you will need to follow the car manufacturer’s recommendations for changing the fluids on a regular schedule. 

The only vehicles that will have transfer cases are those that have either four-wheel or all-wheel drive. A transfer case aims to transmit the necessary power to a suitable set of wheels, either in the rear or front. This transmitting will be done following the settings of a vehicle and the input the case receives. Keep in mind that any failures that occur due to a lack of proper maintenance or abuse of the car will most likely cause you to get denied by your powertrain warranty.

Is Buying a Powertrain Warranty For Your Vehicle Worth it?

In the table below, we will provide you with some highlights of the repair costs for various parts of a powertrain warranty. For this example, we chose to use repair data that Repair Pal provided on a 2014 Chevrolet Malibu. 

Head Gasket Replacement for a 2014 Chevy Malibu

With Complete Car Without Complete Car
Free Approximately $942 to $1,237

Oil Pump Replacement for a 2014 Chevy Malibu

Without Complete Car With Complete Car
Approximately $494 to $941 Free


From this example above, it is easy to see how repair costs can add up. Several powertrain warranties can include coverage for items, including: 

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

How Do Extended Powertrain Warranties Work?

If a car owner decides to purchase an extended powertrain warranty, they do so with the expectation of their vehicle being covered if a malfunction or mechanical failure occurs. There are, however, specific coverage plans which will often offer coverage for only particular things. 

This is why you have to know precisely what is and what is not covered so that you can avoid running into any issues, hassles, or problems when you need to have repairs completed. If you have decided on a vehicle service contract with Complete Car, then you can take your vehicle to any repair facility, so long as it has an ASE-certification. 

The shop where you decide to make repairs will contact Complete Car before making any repairs to report to us that a claim will need to be filed before repairs are started.

Once we have verified that your vehicle service contract is up to date, we pay the repair facility directly for covered repairs. You will be responsible for any deductible costs if there are any required with your plan. Most plans will have deductibles of $100, while others have $50 or even $0 deductibles. So think of it this way, you can receive thousands of dollars worth of repairs by only paying, at most, $100!

Extended Powertrain Warranty Benefits

The smart consumer knows that the better you treat and care for your car, the longer you will have it. This often means that you may diligently commit yourself to the recommended maintenance by the manufacturer. We at Complete Car strongly encourage this being done because routine maintenance is not all that is needed to keep your car protected. 

All vehicles will break down eventually, no matter how well a car has been manufactured. After the manufacturer’s warranty expires, you will be left responsible for paying for any repairs on a vehicle. With the costs of standard repairs costing hundreds or even thousands of dollars in some instances, why would you want not to have some sort of protection for your vehicle in the form of either an extended car warranty or a powertrain warranty? 

When you have a factory powertrain warranty in place, you will not likely face any serious issues as you have a guarantee of protecting you from manufacturer defects. Several automotive research sites will show how the powertrain components are more than likely to fail outside the time frame of your manufacturer’s warranty. A powertrain warranty can help you in many ways outside of protecting consumers from the high costs auto repairs have.

Find Peace of Mind with Complete Car

It can be very stressful and scary when facing a vehicle breakdown. Not knowing what you do, if you can’t afford the repairs on your own, you may need a ride to do many things. 

The good news is that you can save yourself a lot of trouble and even money with a powertrain warranty from Complete Car. The powertrain protection plans with Complete Car include the following:

  • Tire + key fob replacements
  • Coverage terms that go up to 10 years or 150,000 miles or even more!
  • They are accepted by all ASE Certified Mechanics, not just the dealership.
  • Plans and payment options for all budgets.
  • We provide award-winning customer service when you want it.
  • We offer 24/7 Roadside Assistance, so our customers have peace of mind.
  • Claims are paid directly to the repair center.
  • A risk-free 30-day trial period guarantee.

The majority of consumers cannot deal with a situation financially in which they would have to spend hundreds or thousands of dollars on repairing their car. Even if you have the available funds to do so, most would prefer to spend that money elsewhere. 

Resale Value is Increased by Protection Plans

The main reason that extended warranties are popular is the fact that they can increase the resale value. It is often difficult to imagine selling a car that they recently purchased. However, over time your opinion may change. 

If that time comes, an incredible selling point comes from offering a powertrain warranty with Complete Car is a great selling point. It provides more than just the valuable protection you need; it also provides any potential car buyer to know that your vehicle was well maintained and that additional security was necessary if the car was to break down. 

It is so nice to know that you can sell your car later with peace of mind, and it gives potential buyers peace of mind in keeping the resale value intact and even potentially increase it. 

Use a Powertrain Warranty in Order to Save Money on Car Repairs 

The best part about having a powertrain warranty is the amount you can save due to not needing to pay out much in out of pocket expenses. Suppose your vehicle happens to qualify for more than just the powertrain components. In that case, a protection plan through Complete Car can cover all the costs of repairs, even labor and parts for the components listed below:

  • Electronic Components
