The vehicle’s EV system and related electrical components appear to be malfunctioning, causing repeated “EV System Off” error messages and rendering the vehicle inoperable. The vehicle is currently at the dealership and available for inspection upon request. The defect created a significant safety risk because the vehicle became unreliable and could unexpectedly fail to operate, leaving me stranded and without dependable transportation. This placed both myself and others at risk, especially if the failure occurred while driving or in traffic. Yes, the issue has been repeatedly reproduced and confirmed by the Nissan dealership. The vehicle has been towed to the dealership approximately five times for the same or substantially similar issue, and multiple repair attempts and part replacements have been made. The vehicle has been inspected by the Nissan dealership and Nissan Consumer Affairs has been notified on multiple occasions. Repairs and diagnostics were performed between March 20, 2026 and April 10, 2026, and the same issue reoccurred again on May 19, 2026. Yes, warning messages appeared prior to the failures, specifically the “EV System Off” warning message. These symptoms first began prior to the initial repair period in March 2026 and have continued to reoccur despite repair attempts.

I am filing a safety complaint regarding my 2023 Nissan Ariya involving an apparent failure of the 12-volt battery and/or electrical system. While parked overnight in my driveway, powered off, and not plugged in nor charging, the front battery/engine compartment began sizzling, overheating, and producing smoke. The heat caused internal damage and disabled the vehicle. This created a serious fire risk because the incident occurred at my home while the vehicle was unattended and inactive and it happened without any earlier signs or warning. My battery health was checked by the repair shop at the dealership within the last 5 months. The malfunction could have caused a vehicle or house fire and endangered nearby occupants and property. The vehicle is currently at King Windward Nissan in Hawai‘i for inspection and repairs, and a Nissan Consumer Affairs case has been opened. Anecdotally, I have heard from 4 other Nissan Ariya owners in Hawai'i who have experienced similar battery failures with their Nissan Ariyas within the first two-years of purchase.

At approximately 18,500 miles, my 2023 Nissan Ariya experienced a brake system failure while driving. The vehicle exhibited abnormal braking behavior and reduced braking performance, creating a serious safety concern. I was able to safely stop the vehicle, but the failure could have resulted in an accident. The vehicle was taken to a Nissan dealership for inspection. The diagnosis revealed severe and premature wear of the rear brake pads and significant damage to the rear rotors. The dealership also recommended replacement of the entire rear brake assemblies, not just standard wear components. The total repair estimate is approximately $3,800. Safety Concern: This failure occurred at very low mileage. In an electric vehicle with regenerative braking, brake components should last significantly longer under normal conditions. The extent of damage and need for full brake assembly replacement suggests a potential mechanical or electronic defect, such as a caliper malfunction or braking system issue. This was not normal wear and tear. The failure occurred during operation and posed a direct safety risk due to compromised braking ability. Manufacturer Response: The dealership has indicated the issue may not be covered under warranty, classifying it as wear-related. However, the severity and early failure strongly indicate an underlying defect rather than routine wear. I have contacted Nissan Corporate claims for further resolution. When visually inspecting the car the rotors were irregularly worn and the brake lines had burst spilling break fluid all over the rear innner tire .

Recently I been hearing a clicking noise every time I come to a complete stop and when I take off again. It started happening recently. After I hear the click noise coming from the middle of the front of my car, the wheel feels like it’s spinning just a little bit before coming to a stop.
