What should you do?
Consumers should stop using the scooters with the recalled batteries immediately and contact Sublue for a free new generation battery replacement (gray battery). Sublue will provide a battery collection kit for the consumer to return the recalled battery and will provide the replacement battery upon return of the recalled battery.
