The 2021 Nissan Armada's complaint picture is spread thin across a small sample, but a few patterns stand out. The most-reported system is the automatic emergency braking, where multiple owners describe the system triggering unexpectedly at highway speeds with no obstacle present, causing the vehicle to brake hard without warning. On the powertrain side, owners report stalling, bucking, and rough running, sometimes after a fuel stop, along with sluggish acceleration and a jerking sensation at speed. Battery drain shows up in more than one report as well, with owners describing repeated dead batteries and one case of acid leaking from a replacement unit. The transmission and drivetrain complaints are limited to one or two reports of jerking and slow response after fluid service.
