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.
Many complaints state that the battery in their 2021 Sentra drains causing the vehicle to not start.
“Car battery has died 3 times since purchase. Dealership says battery is fine. Have only owned the brand new vehicle about 8 weeks!”
“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.”
“The vehicle inexplicably drained the battery again. Monday July 12, 2021, the vehicle does not start. I take it to the dealer’s service center and they tell me there is no problem with the car or the charging system.”
“Car will not start. Unexplained battery depletion. Trunk will not close when car is not on.”

Tried to start my vehicle and would not start after several attempts car started but half of the gauges did not wotk,including gas guage. Started to drive home after a half hour trying to drive home car dies. Ran out of gas at 230 am. Had to be towed to repair shop. What a pain !
Hi i bought new 2021 nissan sentra and the battery has died just after 1 month and 3 weeks. I took to the dealership and changed it . Month later 2 front axles loses and they changed it. 1 week later the windows couldn’t open and close , then they fixed it for me. The battery has died 6 months later and changed at the same time both axles became noisy but I went to inspect to different mechanics the result was a manufacturing fault. Back to Nissan dealership they fixed it as it was under warranty. 2 years later the alternator was damaged it costed me $1600 with labor. With the battery I am keep changing yearly. This cars are really rubbish. I did try to sell it but even with very cheap no one interested.
My 2022 Nissan Sentra is having these same issues. I’ve charged it up multiple times and it immediately drains out.
I have brought my 2021 Nissan Sentra to the dealer multiple times regarding a battery issue. Now they are requesting I pay a diagnostic fee and battery replacement. I have had to get my car boosted multiple times as well.
My 2019 Nissan Sentra st keeps killing the battery. Alternator is good . Got it new in 2019
