Lucid to update 2,039 Air sedans over inverter defect
Lucid will push an over-the-air software update to 2,039 Air electric sedans in the US after a defect in the Gen 4 inverter can cut drive power without warning. The action covers 2024 and 2025 Air Pure Rear-Wheel Drive vehicles built with that inverter. Lucid filed the action with the National Highway Traffic Safety Administration on May 27, and the agency acknowledged it on May 28.
Lucid Air Pure update
The software is designed to watch for signs of an impending Gen 4 inverter failure and set a diagnostic trouble code before power is lost. Lucid expects the alert to appear in the car as “Drive System Fault, Schedule Service Immediately,” and says drivers should see it at least 100 miles before any actual loss of drive power.
The company said the issue is limited to the single-motor Air Pure. Dual-motor Air models, including Touring and Grand Touring, are excluded from the action.
Gen 4 inverter fault
Lucid says vibration from the motor can travel into the inverter and affect its internal components. Over time, movement can wear the pads and contacts on the gate driver circuit board through fretting, which can interrupt internal signals and trigger a switching module failure. When that module fails, the inverter can no longer convert battery DC power into the AC current that runs the motor.
Lucid said every failure tied to this issue occurred on a Gen 4 unit, and no other inverter generation showed the fault. The company estimated that about 1.6% of the recalled population, or roughly 33 vehicles, actually carries the defect.
May 27 filing
The filing gives owners of the affected Air sedans a repair path before the problem can become a loss-of-power event. Lucid expects to push the over-the-air update around the end of June, bringing the monitoring software to the vehicles covered by the action.
For drivers in the affected group, the practical change is simple: the car is scheduled to receive software that can warn of the inverter issue before drive power drops. The update does not expand the recall beyond the 2,039 Air sedans already identified in the filing.
