So, just what does a powertrain warranty cover? In this guide, we will discuss the ins and outs of powertrain warranties. When you have all the details, you can decide whether you need any additional protection for your vehicle.

What Is A Powertrain Warranty?

A powertrain warranty is a type of limited warranty that covers the cost of repairing or replacing parts of the powertrain, such as the engine, drivetrain, and transmission. The warranty can protect you from costly repairs, as the components of the powertrain are often the most expensive to fix.

What Does A Powertrain Warranty Cover?

A powertrain warranty covers the costs of repairs and replacement parts due to a mechanical breakdown of the powertrain (engine, drivetrain, and transmission. Conversely, a bumper-to-bumper warrant, which is the other most common type of warranty, covers more systems and components for a shorter period of time than a powertrain warranty. 

In order to have the best idea of what powertrain warranties cover, it is important to understand more about (1.) what exactly a powertrain is, and (2.) what isn’t covered in a powertrain warranty, both of which we discuss in the following sections.

What Is A Powertrain?

A car’s powertrain consists of the parts that provide the mechanical energy that moves the car forward. These components include the engine, cylinder block, transmission, driveshafts, transfer case for all-wheel and four-wheel-drive vehicles, supercharger, turbocharger, and differentials.

The powertrain also includes the internal parts of the engine, such as the crankshaft, pistons, timing belt and gears, gaskets, intake and exhaust valves, and the oil pump.

The powertrain is essential for the proper functioning of your vehicle, which has a lot of moving parts – parts that, eventually, could just decide to stop working. That’s where a powertrain warranty can be useful.

What Is Not Included In A Powertrain Warranty?

Powertrain warranties do not cover so-called “wear items” that are designed to wear and tear over time. This includes parts like the battery, clutch, wheel bearings, CV joints, and certain drive belts and fluids.

Factory Powertrain Warranty

An automotive factory warranty usually consists of a bumper-to-bumper warranty and a powertrain warranty plus some other coverages. The “powertrain limited warranty” that comes with a new vehicle covers the powertrain components for a longer period of time than the vehicle’s bumper-to-bumper factory warranty. 

How Long Does A Powertrain Warranty Last?

Powertrain warranty term lengths vary widely by provider. If you purchase a new vehicle with a powertrain warranty, some of the best manufacturers offer coverage for 10 years or 100,000 miles, whichever comes first. Other manufacturers offer 5 years/60,000 miles for their powertrain warranties, including Ford, Dodge, Chevrolet, Chrysler, Honda, Subaru, and more. Below are 11 car manufacturers ranked by their 2022 powertrain warranty length:

Powertrain System Repair Cost

Extended Powertrain Warranty

Even if you have factory powertrain coverage, it’s only a matter of time until your warranty expires, leaving you responsible for any repair bills. For many car owners, purchasing an extended warranty can provide peace of mind. When you consider the average costs of powertrain parts, that peace of mind alone might be worth it.

Can I Extend My Powertrain Warranty?

If you choose to purchase an extended car warranty, your powertrain warranty coverage will be extended for several years, though the exact coverage length will depend on your warranty plan.

Is A Powertrain Warranty Worth It?

If the protection afforded by an extended warranty provides you peace of mind, a powertrain warranty is worth it if it provides the right amount of coverage to fit your needs and budget. 

You should consider an extended powertrain warranty if you’re just looking for protection for essential components like the engine. If you want full coverage for your vehicle, an extended warranty that includes bumper-to-bumper and powertrain coverage is your best bet. On the other hand, you should consider a drivetrain warranty If you want the cheapest coverage available.

We compare the other two coverage levels with powertrain warranties in the sections below: 

Drivetrain vs. Powertrain Warranty

While a powertrain warranty covers all parts of the vehicle’s powertrain, such as the engine, drivetrain, and transmission, a drivetrain warranty only covers the drivetrain. That means that it only covers the components that are responsible for delivering power to the driving wheels, such as the:

  • Torque converter
  • Propeller shaft
  • U-joint
  • Rear-axle
  • Spool
  • Differential

In common practice, powertrain and drivetrain warranties mean the same thing, since the drivetrain is part of the powertrain. Most factory warranties include the engine in this level of coverage, which makes them powertrain warranties.

Bumper-To-Bumper vs. Powertrain Warranty

A powertrain warranty covers only the powertrain, while a bumper-to-bumper warranty covers almost every non-powertrain component from the front bumper to the rear bumper. What exactly is covered by a bumper-to-bumper warranty can differ from provider to provider, so make sure to read the fine print and exclusions.

Contrary to a powertrain warranty which usually outlines the specific components that are covered, a bumper-to-bumper warranty will include a list of exclusions. Generally, a bumper-to-bumper warranty also excludes wear items, such as tires, brake pads, and windshield wipers, and routine maintenance like oil changes and tire rotations.

Buy Powertrain Warranty

You can purchase an extended warranty directly from your automobile manufacturer or a third-party provider like Endurance, CARCHEX, or CarShield. Each option has its advantages and disadvantages, which we discuss in the sections below.

Extended Manufacturer Warranty

If you have a lot of brand loyalty and feel most comfortable signing a contract with your favorite car brand, then a manufacturer-extended powertrain warranty is probably the best choice for you. That said, manufacturer warranties usually have stricter requirements on where you are able to service your vehicle – usually, it’s only in manufacturer dealerships and service centers. You may also have to purchase your extended warranty at the time you purchase your vehicle.

Aftermarket Powertrain Warranty

Aftermarket warranty providers, on the other hand, generally let you service your vehicle at whatever in-network shop you like, giving you a lot more flexibility. Many plans also come with benefits like towing, roadside assistance, trip interruption, and rental car coverage.
