This new warranty could underpin customer confidence in electric vehicles and hybrids.
Cover can be for a variety of periods up to 24 months, and claims can be made at the supplying dealer or almost any other, up to a limit of the vehicle purchase price.
Sean Kent, RAC director of sales at Assurant, said: "This is a very timely development with EVs and hybrids starting to appear on the used market in larger numbers and, for the first time really, outside of franchise dealer networks.
"There is massive public interest in these vehicles but used car customers tend to be quite conservative in their buying choices. The new warranty, which provides the most comprehensive level of cover we have yet offered, is designed to deliver the peace of mind needed for them to feel comfortable with moving away from petrol and diesel power.
"We believe that it could play a key part in building consumer confidence in EVs and hybrids across the market in a general sense.
The warranty covers all of the key components in the EV drivetrain and charge system with the exception of the batteries.
Kent said: "EV and hybrid manufacturers, almost uniformly, include comprehensive battery warranties, typically eight years and 100,000 miles, so our product is designed around this existing cover."
