A number of Leaf owners in Arizona say that the capacity of their vehicles’ lithium-ion batteries fell drastically after just a year of use, sharply limiting their driving range, the Christian Science Monitor noted.
Last year, Nissan tested the vehicles in question and declared them to be working normally. Any accelerated loss in battery capacity was attributed to the owners driving the cars more than recommended by Nissan.
That didn’t sit well with the owners. One said that after 15 months, his vehicle lost 27.5% of battery capacity. That meant his Leaf could only travel 42 miles on a single charge. That was a particular problem since his commute to work runs 45 miles.
When he returned his car to Nissan, he initially had to pay $700 in fees. After he took his case to the media, and online, Nissan issued a full refund. Similar capacity losses in Leaf batteries led to the filing of a class action lawsuit against Nissan in California last week.
Nissan officials said the complaints were confined to a small number of Leaf owners and that the repurchases were not an admission of any defect in the Leaf.
