Nissan will be contacting the owners of certain 2013-2015 Nissan Leaf vehicles about a problem that could result in extended braking distances. According to the defect report, the relay inside the electronic brake booster could freeze in cold temperatures. If this occurs, the vehicle will illuminate the brake warning lamp and the system will set to “assist mode”. More pedal effort and increased braking distances could increase the risk of an accident.

Dealers will correct the problem by reprogramming the Intelligent Brake Control Unit software. Owners wanting more information about the problem are asked to contact Nissan customer service at 1-800-647-7261. The NHTSA campaign number is 16V-119.
