Summary
The Nissan Ariya has 8 recalls, all affecting the 2023 model year, with the most serious being a steering wheel that may have a loose or missing attachment bolt, allowing the wheel to detach from the column and leave the driver with no steering control.
The remaining recalls all involve unexpected loss of drive power on 2023 vehicles. The inverter software can misdiagnose an electrical fault and shut down the drive system, cutting power to the wheels without warning. A related inverter issue involves the software incorrectly detecting a short circuit and triggering the same shutdown. On the mechanical side, O-rings inside the front electric motor can be damaged from assembly, allowing oil to leak inside the motor and push the vehicle into a fail-safe mode that cuts drive power. A separate issue with the electric motor seals can produce the same result through internal oil contamination. There is also a condition where a momentary over-current in the drive motor activates fail-safe mode and drops power to the wheels, and another where a software fault triggers fail-safe mode on its own, again without warning. In all of these cases, the vehicle can lose forward drive unexpectedly, raising the risk of a crash, particularly at highway speeds or in traffic.
