Is There a Problem with the Battery in the 2021 Nissan Sentra?
Yes, the National Highway Traffic Safety Administration (NHTSA) has logged several consumer complaints from vehicle owners regarding a battery issue in the 2021 Sentra. More specifically, the battery drains causing the vehicle to not start inconveniencing owners.
Nissan issued several technical service bulletins for this issue with the most recent, NTB21-053B on September 2, 2021. The cause of the issue is from the audio unit/infotainment system. A dealer campaign bulletin issued (Reference: PM991) on July 27, 2021 explains this issue in detail stating:
Due to a program logic concern, certain vehicles may have been manufactured with an Alliance In-Vehicle infotainment (AIVI) system software that allows the AIVI system to continue drawing current after the vehicle is shut off.”
The bulletin goes on to state that certain actions such as pressing the brake pedal after the car is shut off may cause the infotainment system to “wake up” and stay active until the vehicle is turned on again. If the vehicle isn’t started within 46 hours, the battery may completely discharge.

An owner from Puerto Rico filed a complaint on the NHTSA website stating:
“Suddenly the battery ran out on Tuesday, July 6, 2021, 18 days after I bought the car. The car did not want to start from the beeper. When I got into the car to start it, my battery was completely drained. A roadside service technician starts the car with a battery booster. On the way to the auto dealership shop, the vehicle would not accept cruise control. I arrive at the auto dealership workshop and they verify the unit. And according to them it did not duplicate any of the problems that the vehicle presented. Claiming that the charging system was fine and the battery was fine.”
