The fuel pressure sensors may not have been sufficiently tightened during production. As a result, the fuel pressure sensor may loosen with vehicle usage and cause a fuel leak.

Consequence: A fuel leak in the presence of an ignition source could cause a vehicle fire.

Remedy: Nissan will notify owners, and dealers will re-torque the fuel pressure sensors free of charge. The recall began on January 25, 2015. Owners may contact Nissan customer service at 1-800-647-7261.
