EV warranty coverage
EVs come with similar factory warranty protection to gas-powered cars. EV warranty coverage typically includes the following.
Bumper-to-bumper warranty
EVs come with a basic limited warranty, or a bumper-to-bumper warranty, that covers most of the car. This warranty covers manufacturing defects, such as issues with navigation systems or power seats. These warranties usually last three years or 36,000 miles, with some lasting up to five years or 60,000 miles.
Powertrain warranty
For an EV, the powertrain warranty generally covers the drive unit, battery packs, electric motors and hybrid components. Powertrain warranties for EVs typically last at least five years or 60,000 miles.

Battery warranty
Modern EVs come with a high-voltage battery warranty for at least eight years or 100,000 miles. At a minimum, EV battery warranties must cover total failure and malfunction, such as low voltage or no charging. Some automakers also cover degradation in their battery warranties, which protects you if you have a natural loss of range and power with time and use.
EV battery warranties must cover total failure and malfunction, though some may also cover some level of degradation.
For example, Tesla guarantees that you’ll retain at least 70% of your battery capacity for at least the first eight years or 100,000 to 150,000 miles, depending on your vehicle model.

What does an EV warranty not cover?
EV warranties typically don’t cover:
Wear and tear
Like gas-powered cars, EV warranties don’t cover wear-and-tear items like tires, wiper blades and most brake components, like brake pads and rotors.
Neglect
EV batteries require regular software updates and maintenance, such as checking the battery coolant or brake fluid levels. Any issues related to neglect will not be covered under an EV warranty.
Some degradation
Most automakers will guarantee at least 70% to 75% charge retention for the first eight years or 100,000 miles, but any degradation beyond this timeline won’t be covered.

Damage, abuse or misuse
EV warranties don’t cover damage from:
- Nonstandard charging
- Nonrated towing or being improperly towed
- Collisions
- Weather
- Ignored warnings
- Unauthorized servicing or repairs
- Aftermarket parts
- Software tampering
- Battery exposure to water or flame
- Abuse or misuse
FAQ
Are EV battery warranties transferable?
EV warranties can generally be transferred to a new owner. Some automakers ask that you fill out paperwork to transfer any and all remaining factory warranties to a new owner. Other automakers may let you transfer the limited and battery warranties, but may reduce the powertrain warranty. It’s always best to check with your specific EV automaker to confirm that the warranty is transferable if you’re thinking of selling your EV eventually.
How long do EV batteries last?
EV batteries can last 10 to 20 years with proper care. If you live in the northern U.S., your battery can age faster due to frigid temperatures. In this case, it can be helpful to choose an EV manufacturer that covers degradation.

Can you buy a used EV?
You can typically buy a used EV. If you’re interested in this option, be sure to get a pre-purchase inspection that includes a thorough battery test. It’s also a good idea to run the vehicle identification number (VIN) by the automaker to ensure the factory warranty hasn’t been voided, particularly the battery warranty. You can also check Carfax for a vehicle’s accident history.
Can you get extended warranty coverage for EVs?
It’s generally harder to get extended warranty coverage for EVs than gas-powered cars. Some providers may offer bumper-to-bumper or powertrain warranties, but many of them don’t cover batteries.
Bottom line
EVs typically include a bumper-to-bumper warranty, a powertrain warranty and a separate high-voltage battery warranty from the factory. The battery warranty generally ensures that the battery pack lasts for at least eight years or 100,000 miles without major malfunction. While that may sound lengthy, it’s still worth looking into EVs with longer battery warranties, degradation protection or ideally both.
