    NIO recalls 686 Firefly EVs over steering sensor defect risk

    Recall announced

    NIO Auto Technology (Anhui) Co., Ltd. filed a recall plan with China's State Administration for Market Regulation defect product recall technical center to recall 686 Firefly (萤火虫) 2026-model 42kWh battery electric vehicles produced between March 20, 2026 and April 2, 2026 (recall No. S2026M0114V). Due to a manufacturing process fluctuation, the steering column torque sensor harness may interfere with the sensor rotor, which in extreme cases can cause abnormal sensor signals, illuminate the electronic steering system fault light, and lead to loss of steering assist. Regulators have received 7 related complaints, with no reports of accidents or injuries. The company will inspect the harness and rotor for interference and replace the harness free of charge where needed, and will correct the harness installation process in production; the recall implementation period runs until December 18, 2026.

    Stated objective. Eliminate the potential safety hazard (owners urged to complete the free inspection as early as possible)

    Firefly Alpha rocket lost after in-flight explosion

    Safety incident

    Firefly launched its Alpha rocket from Vandenberg Space Force Base, but an anomaly resulted in an explosion and the total loss of the vehicle before it reached space. The company stated that ground staff had cleared the pad and surrounding areas to minimize risk. The event is noted as a controversy involving the loss of the launch vehicle during flight.

    Company response

    • Remediation — Firefly

      It added that the ground staff had cleared the pad and surrounding areas in order to minimize risk and in adherence with safety protocols.

    Source excerpt

    • Firefly launched its first rocket from Vandenberg Space Force Base in California, and on board it carried a number of payloads with an intended destination of low-Earth orbit.
    • The rocket took off as planned, and seemed to be doing fairly well during the initial portion of the launch, before experiencing “an anomaly” that clearly resulted in an explosion and the total loss of the vehicle prior to reaching space.
