2017-2018 BMW C Evolution Scooters Recalled For Corroded Wiring
Corroded contacts may pose fire risk
BMW is recalling the 2017 and 2018 C Evolution electric scooter because of a risk of corroded wiring that may lead to overheating or a fire. The recall affects 116 scooters in the U.S. market.
According to recall documentation released by the U.S. National Highway Traffic Safety Administration, water splashing from the front wheel may come in contact with the 12V battery’s ground cable lug, which may lack sufficient waterproofing.
It is possible that water may wick its way along the cable, due to capillary action, and reach the plug connector on the DC/DC converter. Over time, this may cause the electrical contacts to corrode, which can lead to localized heat generation and, in extreme cases, could pose a fire risk.
BMW received a report of a thermal event on a 2020 C Evolution in another market on June 25, 2025. BMW initiated an investigation, focusing on the connection between the 12V battery and the DC/DC converter. A second thermal event, also from outside the U.S., was reported on July 16, 2025.
The investigation quickly determined the 12V connector could be susceptible to internal corrosion, but it took much longer to identify the ground cable lug on the front part of the 12V battery as the source. BMW decided to initiate recall procedures on May 7, 2026.
BMW dealers will replace segments of the main wiring harness with the ground cable lug with one with improved waterproofing. Dealers will also check for signs of corrosion in other sections of the main wiring harness, and replace them if necessary. Owners should begin receiving notices in July.

This is just another reason to never buy battery powered gimmicks especially German products!
