When you purchase a new vehicle, it will most likely come with a manufacturer-backed powertrain warranty. But what does a powertrain warranty cover?
In this article, we’ll discuss powertrain warranty coverage in detail, including coverage, exclusions, term lengths and differences between powertrain warranties and other vehicle protections. We’ll also discuss the cost of extended powertrain warranties and whether it’s worth the investment.
We’ve reviewed the best extended car warranty companies on the market, and below, we’ll discuss the powertrain coverage plans offered by our top recommended providers.
Best Extended Car Warranty Companies
We reviewed every major warranty company for coverage, affordability and more. Here are our recommendations.
What Does a Powertrain Warranty Include?
A powertrain warranty protects the engine, transmission and drivetrain – a car’s vital components. The engine converts fuel into power, making your vehicle move. Your transmission regulates how much power goes to your wheels, so you can drive at a certain speed. The drivetrain, also called a drive axle, transfers power to the wheels.
To give you a better understanding of what a powertrain warranty covers, we’ve detailed the Honda warranty’s powertrain coverage for a 2021 Honda CR-V below.

What Does a Powertrain Warranty Not Include?
A powertrain warranty does not protect nearly as many components as a bumper-to-bumper warranty. For example, a powertrain warranty does not cover a car’s air conditioning, infotainment system or electrical system.
Other exclusions typically include:
- Normal wear-and-tear parts like brake pads
- Tires and wheels
- Damage caused by misuse or abuse
- Damage caused by a collision
- Environmental damage
- Routine maintenance
What’s the Difference Between Powertrain and Other Warranties?
The most common warranties you’ll see offered by manufacturers or third-party providers are powertrain and bumper-to-bumper warranties. Another warranty that can be confused with powertrain coverage is a drivetrain warranty. So, how do these three coverages differ?
Bumper-to-Bumper Warranty
Bumper-to-bumper coverage is commonly offered alongside powertrain coverage as part of a new car factory warranty. Also called comprehensive or exclusionary coverage, bumper-to-bumper warranties protect almost all major systems and parts of your vehicle, except for a short list of exclusions.
Typically, bumper-to-bumper warranties have shorter term limits than powertrain warranties. They can also be much more expensive when you’re purchasing extended coverage. However, bumper-to-bumper coverage goes far beyond your vehicle’s engine, transmission and drive axle, giving you the ultimate peace of mind. This protection also excludes routine maintenance, wear-and-tear parts and damage caused by outside forces.
Drivetrain Warranty
Many drivers think a vehicle’s drivetrain and powertrain are the same, but in fact, the drivetrain is a part of the powertrain. A drivetrain warranty will typically only cover your car’s torque converter, propeller shaft, universal-joint (U-joint), rear axle, spool and differential.
How Long Does a Powertrain Warranty Last?
New vehicle powertrain warranties last anywhere from 4 years/50,000 miles to 10 years/100,000 miles, depending on the manufacturer. The longest powertrain warranties on the market – lasting 10 years/100,000 miles – are currently offered by Kia, Genesis, Hyundai and Mitsubishi. Popular commuter brands like Honda and Toyota offer powertrain coverage lasting 5 years/60,000 miles.

Should You Buy a Powertrain Warranty?
After your powertrain warranty expires, an extended auto warranty can protect you from footing the bill for expensive engine, transmission and drive axle repairs. According to RepairPal, the average cost to replace an entire transmission is between $5,401 and $5,696. Thankfully, you’ll likely need to repair transmission components instead of replacing the whole system, but even minor powertrain repairs can be costly.
If you’re thinking about purchasing additional powertrain coverage, take your vehicle’s reliability and your financial situation into account. Drivers with highly reliable cars may not need to invest in extra coverage. The same is true for those who have a budget set aside for auto repairs. However, many drivers find that the peace of mind offered by an extended warranty is worth the price.
To give you a better idea of what repairs might cost to, here are some commonly reported powertrain issues and their respective costs:
| Repair | Cost |
|---|---|
| Fuel pump replacement | $638 to $837 |
| Timing belt replacement | $765 to $952 |
| Radiator replacement | $715 to $940 |
| Thermostat replacement | $270 to $326 |
| Head gasket replacement | $1,802 to $2,292 |

Manufacturer vs. Third-Party Powertrain Coverage
An extended warranty will typically be offered to you at the dealership when you purchase a new vehicle, but getting coverage from a third-party provider often gives you more flexibility when it comes to coverage, pricing and repair facility options.
Manufacturers guarantee factory-trained technicians and the use of genuine replacement parts, but their typically high-cost contracts and strict vehicle eligibility requirements may not be the right choice for you.
Cost of an Extended Powertrain Warranty
While the cost of powertrain coverage varies from manufacturer to manufacturer, we found that independent providers’ powertrain contracts cost, on average, $649 per year of coverage. Below, we’ve detailed powertrain warranty quotes from some of our top-recommended providers. These quotes were for a 2012 Chevrolet Equinox with 90,000 miles.
