Chronology :

September 20th, 2022: Two Gen2 EZ10 vehicles were parked and charging at the same location. One vehicle caught fire and the other was smoking.

September 21, 2022: EasyMile initiated an investigation into the cause of the September 20, 2022 Gen2 EZ10 vehicle fire incident and the cause of the separate September 20, 2022 Gen2 EZ10 vehicle smoking incident.

September 22, 2022 to November 25, 2022: Examinations of the two Gen2 EZ10 vehicles involved in the September 20, 2022 fire and smoking incidents indicated the fire and smoke were caused by the vehicles’ 48V batteries. EasyMile communicated with NHTSA in late September and early October regarding the September 21 incidents. As a precautionary measure, and at NHTSA’s direction, EasyMile instructed the two owners of the other Gen2 EZ10 vehicles equipped with 48V batteries to disconnect the batteries from the Gen2 EZ10 vehicles and to stop using the affected batteries. During its communications with NHTSA, NHTSA verbally told EasyMile to file a 573 report. Based on the available information, EasyMile determined that the 48V batteries on the four Gen2 EZ10 vehicles may be defective. After reviewing this information, Easymile determined the potential fire risk constituted a safety-related defect.
