FUEL SYSTEM, GASOLINE28/11/2014

Nissan North America, Inc. (Nissan) is recalling certain model year 2012-2014 Nissan Juke, 2012-2013 Infiniti M56, QX56, and 2014-2015 Infiniti Q70 (V8 engine vehicles only), and QX80 vehicles. 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.

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

Fix: 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.
