New electric cars may be less reliable than petrol and diesel models, according to a survey.

A poll by consumer group Which? found that 31% of electric car owners reported a problem with their vehicle in its first four years.

That compared with 19% of people with petrol cars, and 29% with diesel cars.

The survey also found that faulty electric vehicles spend longer off the road – five days, compared with just three and four days for petrol and diesel cars respectively.

The survey appears to contradict the common perception that electric vehicles are more reliable than petrol or diesel cars because they have fewer moving parts.
