Certain engines were assembled with a zinc coating applied to a terminal stud bolt that is thicker than specification. This can result in a poor electrical connection that may cause stalling, difficulty starting, and damage to the engine control module. If the engine were to stall while driving, the likelihood of a crash would increase. Dealers will replace the positive battery terminal and cover to correct this concern.

Nissan Recalls 2010–2011 Sentras Due to Gap in Contact Area of Battery Terminal

RepairPal Expert Overview:
Nissan is recalling 2010–2011 Sentra models due a machining irregularity on the bolt/washer surface of the positive battery terminal cable end that causes a gap to occur in the contact area of the terminal. This may cause the engine to stop running while the vehicle is in motion at low speed with a hard or no start, which increases the risk of a crash. Dealers will replace the positive battery terminal cable end with a new one, free of charge.
