The original Nissan Leaf is ageing rather well. Although 12% of owners of previous-generation models reported faults, all of these were rectified for free by Nissan dealers. What’s more, all work was carried out in a day or less.
Owner’s view "This is my second electric car and I think they’re only getting better. Reliability has been excellent"
Reliability rating 96.5%
Bodywork and steering were the only troublesome areas for ZS EV owners, who told us that 13% of their cars had suffered a fault in the previous year. The cost of repairs was covered by MG in all cases, and 60% of the faulty cars were put right in less than a week.
Reliability rating 95.8%
Among e-Niro owners surveyed, only 8% reported a fault. A small percentage of these issues concerned the main battery pack and the 12-volt battery, and there were niggles with some other electrical components. All repairs were done under warranty, but more than 70% of the cars were off the road for more than a week.

Reliability rating 89.7%
The latest Leaf has been stricken by far more faults than the original model; owners told us 45% of their cars had gone wrong, with problem areas including the electric motor battery, 12-volt battery and a range of other electrical systems. Although all cars were fixed for free, 9% spent more than a week in the garage.
Reliability rating 92.6%
Zoe owners said that 24% of their cars had been troublesome, with issues affecting the air-con, bodywork, electric motor and non-motor electrics. Although 75% of the faulty cars were fixed for free, the remaining 25% left owners with bills exceeding £1500, and 25% of them spent more than a week off the road.
