Nissan will be contacting the owners of certain 2012-2013 Infiniti M35 hybrid vehicles about a software update affecting the propulsion system. These vehicles are equipped with a power train that warns the driver in the event of a cooling system malfunction. If the warning lamp is ignored and the vehicle continues to be operated, the power train control module logic will shut off the engine to prevent damage. If the engine unexpectedly stops while driving, the brake and steering systems remain operational, however, there is an increased risk of an accident.
Dealers will reprogram the software for the hybrid control module, automatic transmission control unit and inverter. to include logic that will allow the engine to continue operating at reduced power in the event of a cooling system malfunction. Owners wanting more information about the problem are asked to contact Nissan customer service at 1-800-647-7261. The NHTSA campaign number for this recall is 16V-527.
