Nissan has said it will launch a voluntarily repair service campaign for its Leaf electric vehicle to address problems of some vehicles being unable to start, according to reports.

The company has received reports from Leaf owners where the car has failed to start, and will reprogram software in the Vehicle Control Module to address incorrect diagnosis programming.

Even though the glitch has only affected a small proportion of vehicles, Nissan says all 8,000 or so Leafs made in the US and Japan are covered by the repair service. The company says that this is not a safety-related issue (hence, it’s not officially tagged as a recall) and will not cause the vehicle to stop running while being driven, just that the car may not restart once it is off.
