What Is A Powertrain?

The powertrain consists of the parts that essentially provide power to the wheels of your car. These components include the engine, transmission, driveshafts, transfer case for all-wheel and four-wheel drive vehicles, differentials, suspension, and constant velocity joints, as well as the internal parts of the engine, such as the crankshaft, pistons, timing belt and gears, intake and exhaust valves, and the oil pump, among other items.

The powertrain is essential for the proper functioning of your vehicle and 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 Does A Powertrain Warranty Cover?

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.

It should be noted that the powertrain warranty does not cover so-called "wear items" that are designed to wear and tear over time. This includes parts like the battery, clutch, and certain drive belts and fluids.

Powertrain Warranty Vs Drivetrain 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

Powertrain Warranty Vs Bumper-To-Bumper 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.

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 automakers may only offer 4 years/50,000 miles. Here are the top new car warranties and the length of their powertrain warranties:

New Car Warranty Powertrain
1. Hyundai 10 years/100,000 miles
2. Kia 10 years/100,000 miles
3. Genesis 10 years/100,000 miles
4. Volkswagen 6 years/72,000 miles
5. Mitsubishi 10 years/100,000 miles
6. Jaguar 5 years/60,000 miles
7. Infiniti 6 years/70,000 miles
8. Lincoln 6 years/70,000 miles
9. Tesla 8 years/mileage varies by model
10. Cadillac 6 years/70,000 miles

Once the manufacturer's powertrain warranty expires, you are responsible for the costs of repairs, unless you decide to purchase an extended 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.

Why You Might Need An Extended Warranty

For many car owners, purchasing an extended warranty can provide peace of mind. 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. When you consider the average costs of powertrain parts, that peace of mind alone might be worth it.

Powertrain Component Average Cost*
Timing Chain Replacement $1,266–$1,871
Oil Pan Replacement $728–$956
Water Pump Replacement $301–$653
Engine Control Module $919–$1,076
Transfer Case Replacement $2,466–$2,884
Transmission Mount Replacement $139–$267
Axle Shaft Replacement $485– $607
CV Joints Replacement $2,622–$2,923
Axle Seal Replacement $158–$326

If you’re just looking for protection for essential components like the engine, then you should consider an extended powertrain warranty. If you want full coverage for your vehicle, an extended warranty that includes both bumper-to-bumper and powertrain coverage is your best bet. 

Where Can You Purchase An Extended Warranty?

Extended warranties can be purchased either directly from your automobile manufacturer or from a third-party provider like Endurance, CARCHEX, or CarShield.

Each option has its advantages and disadvantages. If you have a lot of brand loyalty and feel most comfortable signing a contract with your favorite car brand, then that’s probably the best choice for you. However, manufacturer warranties usually have stricter requirements on where you can 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 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.
