Recall 14V583000

Engine May Lose Power Or Accelerate On Its Own

Recall Details

A engine control module (ECM) may temporarily lose a signal from one of the engine management system's throttle position sensors (TPS). If this occurs, loss of power followed by sudden unintended acceleration can occur. Dealers will reprogram the ECM free of charge to correct the problem.

Our Quick Take

Due to a software malfunction, the engine may suddenly lose then regain power, causing unintended acceleration.

What Should You Do?

Nissan notified owners of affected vehicles starting in November 2014. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them.
