2020 Nissan Armada Electrical System Problems

Here’s a full response you can paste into the NHTSA.gov form text box that directly answers all of the questions shown in your screenshot: ⸻ Component/System: The battery and electrical charging system on my 2020 Nissan Armada have repeatedly failed. The vehicle experiences sudden and unexplained battery drain even after regular driving. The vehicle is available for inspection upon request. Safety Risk: This issue has caused my vehicle to fail to start on at least five separate occasions over the past month. I have been stranded in public places, including with my children, and now must carry a battery jump starter at all times. This is a safety concern, especially if the failure happens at night, in a remote location, during extreme weather, or in an emergency. The vehicle cannot be trusted to start reliably, putting me and others at risk. Confirmed by Dealer or Service Center: Not yet. I have not reported this specific battery issue to the dealership yet, as I have been tracking the frequency and pattern of failures before pursuing service. However, based on research, this appears to be a recurring issue with 2020 Nissan Armadas and may relate to an electrical or alternator defect. Inspected by Manufacturer, Police, or Insurance: No. The vehicle has not yet been inspected by Nissan corporate, law enforcement, or insurance. It has not been in a crash. Warning Lamps or Symptoms: There were no dashboard alerts, warning lights, or error messages before each battery failure. The issue started about a month ago and has occurred five times since, always resolved temporarily by using a jump box. The battery appears to drain randomly when the car is off, despite recent driving.

BCI Malfunction light will occasionally come on and dealer unable to explain why and when they have its led to brake swich. Twice in two years this has also led to them replacing the Brake switch in under 40K miles. now at 53 k miles brake switch is causing issues for the third time.

What component or system failed or malfunctioned, and is it available for inspection upon request? The electrical system and battery/charging system of my 2020 Nissan Armada have repeatedly failed. The vehicle experiences unexplained battery drain, even after extended driving. The issue is ongoing and the vehicle is currently connected to a trickle charger in my garage to remain operational. I am willing to make the vehicle available for inspection upon request. How was your safety or the safety of others put at risk? This defect has caused my vehicle to become inoperable without warning, leaving me stranded multiple times, including once after work at night. I now must carry a portable jump starter at all times. This is a serious safety concern, especially if the battery failure were to occur in a remote area, during extreme weather, or in an emergency situation. I can no longer rely on my vehicle to start normally. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue has been confirmed and documented by Arlington Heights Nissan (Illinois). I have had the battery replaced twice, but the issue continues. The master mechanic at the dealership even admitted he owns the same model and uses a trickle charger himself. He stated that the root cause may be the “smart alternator” system, and the only fix they offered was to cut a wire for $300. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Yes. The vehicle has been inspected multiple times by an authorized Nissan dealership. It has not been reviewed by police or insurance, as the issue has not led to a collision, but remains an ongoing safety risk. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure? When did they first appear? There were no warning lights or dashboard alerts before each battery failure. The issue began shortly after I took delivery of it

The 2020 Nissan Armada Platinum began with a BCI Malfunction notification on the dash, as well as multiple other warning lights illuminating on the same time on the dash. As well the low windshield washer fluid light came on after just changing the oil and checking fluids in mid-June. Reservoir was filled with additional washer fluid, the notification went off, but returned 30 minutes later despite the reservoir being full. Later in the day, the gear shift would not immediately engage to allow me to put the car into drive. While sitting at a stop light in a turn lane the car was put into Park to adjust the Navigation settings. From that point, the car would not shift into any other gear to make the car operational. Panicked and blocking traffic in the road, the car was turned off in the hopes it could be turned back on and it would engage the gear shift. The Armada would not start after that point at all. I sat for ten minutes attempting to restart the car, constantly having to get out of my car to waive traffic around me, putting myself at risk of being hit. Thankfully, a local Fire Dept was coming back from a call, and stopped to assist me. They blocked traffic to my right with their fire engine, and a family member came and blocked traffic from behind me with their vehicle to keep me safer than I had been. The Firemen tried everything they could to get the car to start to get the car to safety as we contacted a tow truck. With no success after another 20 minutes, they had to get a long screwdriver from the fire engine to release the shift lock to be able to put the Armada in Neutral. It took three firemen, and a family member to be able to push the car across three lanes of traffic, with the fire engine driving alongside my right to block traffic, pushing me into a busy intersection (at one point with an 18-wheel coming at us) to make a right onto the connecting street to a gas station parking lot to await a tow to the dealership. So scary!
