Electric car warranty and battery warranty

Worried about the battery in your electric vehicle? You shouldn’t, there are extensive warranties in place to ensure they last for years to come

Reliability is a key for any car buyer, be that for new, used, electric, hybrid petrol or diesel vehicles. To give buyers a piece of mind, manufacturers offer their cars with warranties – a promise that if things go wrong, they’ll carry out repairs free of charge.

Warranties vary in their scope and length, but the good news is that electric vehicles are no different to conventional cars. Despite a completely different drivetrain, they come with the same generous promises that manufacturers attach to petrol and diesel models.

What is an electric car warranty like?

These differ between manufacturers. However, most split their warranty policies between the vehicle and batteries on board.

Volkswagen, for example, gives a three-year, 60,000 mile warranty on its e-Golf electric vehicle. For the same model, it also supplies an eight-year 99,360 mile high-voltage battery warranty.

The vehicle warranty covers things like manufacturer defects – say the boot hatch stops opening suddenly. It also covers the paint against manufacturer defects, and there’s a 12-year rust policy.

Specific parts covered under an dedicated electrical vehicle component warranties often include the electric motors, inverter, reduction gear, cables and charge connectors.

The lengths of warranties differs, too. Kia covers its electric vehicles under its excellent seven-year policy. The coverage includes both the vehicle and the electric drivetrain on board. So instead of a separate battery warranty, Kia’s policy covers the two.

Nissan, on the other hand, supplies a three-year/60,000 mile warranty on its new Leaf, and an eight-year/100,000 mile policy on its battery and electrical systems.

It’s important to read the terms and conditions of each policy.

What is covered in a battery warranty?

The big relief with a battery warranty is that it covers owners in case the battery performance drops significantly. All batteries degrade over time, which will have a decreasing effect on the range of the electric vehicle.

As such, manufacturers commit to repairing or replacing the battery if the deterioration falls beyond what is to be expected. This, again, differs between makes, but most limit this to around 70 to 75 per cent of the original performance. Nissan, for example, guarantees its batteries against capacity loss greater than nine bars out of 12 during its policy.

Can I get an aftermarket policy on a used electric vehicle?

Yes. A few years ago, this was difficult, but since then many aftermarket and third-party providers have moved to the sector. Warrantywise became the first aftermarket provider to cover electric vehicles and others have since moved to the sector.

To find the best deal for your electric vehicle or hybrid, it’s best to contact each of the providers and see what they can offer.
