NHTSA complaints for the 2021 Nissan Armada, grouped by the part owners named. Open a row to read what goes wrong.
Batteries drain and leave the SUV stranded, and replacing them does not always fix it. Reports describe repeated battery swaps, acid leaking from a new battery, and a stall with overheating that a dealer traced to a low-voltage battery around 34,000 miles. Another complaint describes all the screens going black and the parking sensors braking the car hard without warning, starting around 10,000 miles. That false braking later spreads to highway speeds. Sudden hard braking in traffic creates a real crash risk.
Bucking, sputtering and stalling lead the complaints. Some vehicles restart only to a rough idle and then die again. One stall happens while merging onto an interstate at night, a serious crash risk. A faulty fuel pump is the suspected cause, and the cost of a tow adds to the pump repair. Other reports describe a drained battery that keeps the vehicle from starting, and a loud engine noise while RPM swings rapidly between 1000 and 3000.
Transmissions fail outright and need full replacement. The first signs are jerking and slow acceleration, and switching to a higher fuel grade does not help. One failure comes at 100,000 miles on a vehicle described as properly maintained. Another appears shortly after a routine differential and transmission fluid service. Nissan's consumer affairs office offers no help in at least one case. Jerking and weak acceleration while driving are a safety concern.
