Inverter May Fail and Cause a Loss of Drive Power

Affected vehicles (1)

Component / system

Defect

Lucid USA, Inc. (Lucid) is recalling certain 2024-2025 Air vehicles equipped with rear-wheel drive. The Gen 4 inverter may experience internal friction and become damaged, causing a loss of drive power.

Risk / consequence

A loss of drive power increases the risk of a crash.

Remedy

Lucid will release an over-the-air (OTA) software update to continually inspect for an inverter failure. If a failure is detected Lucid will replace the inverter, free of charge. Owner notification letters were mailed July 8, 2026. Owners may contact Lucid at 1-888-995-8243. Lucid's number for this recall is SR-26-05-0.

Chronology of events

1. March 2025

   Beginning in March 2025, Lucid became aware of inverter failures on Lucid Air Pure RWD vehicles that were used by a fleet operator. Lucid believed that these vehicles had different driving patterns and accumulated miles more quickly than non-fleet vehicles. A few months later, Lucid became aware of inverter failures on Air Pure RWD non-fleet vehicles. Lucid conducted an investigation relating to the failures and referred the issue to Lucid’s Product Safety Working Group (“PSWG”). From March 2025 to March 2026, Lucid became aware of 55 inverter failures attributable to this issue, including one that was also reported to NHTSA as a VOQ. Lucid investigated to determine the root cause of the failures and affected vehicle population, and analyzed any safety risk therefrom. Lucid’s analysis showed that all of the vehicles with the failure had Gen 4 inverters. There were no failures due to this issue on vehicles with any other generation of inverter. Lucid examined variations within the Gen 4 inverters, as some Gen 4 inverters contained epoxy while others did not. Lucid’s analysis indicated that all Gen 4 inverters could experience the failure. While Lucid was investigating the issue, Lucid evaluated whether temperature contributed to the condition. Lucid developed software-based RDU cooling optimization, though results did not show a quantifiable mitigation benefit. Ultimately, Lucid’s investigation concluded that the inverter failure was attributable to fretting of internal components inside the Gen 4 inverter. While Lucid was investigating the issue, Lucid also worked to improve detection of potential failures prior to failure by using a neighboring signal temperature deviation as a proxy. A Fleet Health Monitoring ("FHM") alert was deployed, which issued an alert to Lucid when the underlying logic was triggered. Lucid worked to enhance the robustness of the FHM detection, implemented improvements in November 2025, and also began contacting the owners of the vehicles that triggered the FHM alert to request that they bring their vehicles in for service. After making this logic change, Lucid became aware of some failures that were not detected by the FHM logic prior to failure. Lucid believes that improving the sampling rate will improve the accuracy of the FHM detection prior to failure, and Lucid is implementing the new logic. Lucid is also implementing enhanced in-vehicle owner notification. As an interim step, vehicles will have a latched warning when certain conditions are met. As a final step, Lucid is planning to deploy via an over-the air (OTA) software update more sensitive logic to trigger an in-vehicle notification that will provide a hard latched warning to drivers, requiring clearing by Lucid Service. The PSWG referred this issue to Lucid’s Product Safety Executive Council (“PSEC”). On May 6, 2026, the PSEC determined that certain MY2024-2025 Air Pure RWD vehicles equipped with a Gen 4 inverter may experience an unwarned loss of drive power and therefore decided to recall the vehicles for a safety-related defect. The PSEC determined that the risk would be mitigated by release of an OTA software update that provides an adequate warning to drivers. Vehicles that receive a warning may be brought to a Lucid Service Center for inspection and replacement of hardware with a non-Gen 4 inverter if necessary.
