Electric scooter sharing company Lime has pulled a number of Segway Ninebot scooters from its fleet after learning that a manufacturing defect could result in batteries “smoldering or, in some cases, catching fire.”

According to the company’s statement, it first learned of the issue in August. Working independently and with Segway, Lime created software to identify the scooters with these batteries, and deactivated them once identified. A Lime representative speaking to The Washington Post said that in an effort to be abundantly cautious, around 2,000 scooters were recalled in Los Angeles, San Diego, and Lake Tahoe.
