Recalls

3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Fuel system Vehicle recall #14V683000 · 2014 · 133,592 vehicles

What's wrong: 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.

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

The fix: Nissan will notify owners, and dealers will re-torque the fuel pressure sensors free of charge. The recall began on January 25, 2015.

Transmission & drivetrain Vehicle recall #20V755000 · 2020 · 2,708 vehicles

What's wrong: Nissan north america, Inc. (Nissan) is recalling certain 2011-2013 Infiniti m56, 2012-2013 m35 hybrid, and 2014 q70 and q70 hybrid vehicles. These models, equipped with 2wd and with a hybrid or vk56 powertrain, have a driveshaft that May break.

Why it matters: A broken driveshaft can cause a loss of propulsion, increasing the risk of a crash, or May disable the parking brake, increasing the risk of a rollaway and injury.

The fix: Infiniti will notify owners, and dealers will replace the driveshaft, free of charge. The recall began February 5, 2021.

Why it matters: A broken driveshaft can result in a loss of drive power, or a vehicle roll away when the vehicle is in park without the parking brake applied. Both scenarios can increase the risk of a crash.

The fix: Dealers will replace the driveshaft, free of charge. Owner notification letters were mailed August 13, 2024.
